Acceso, uso y conservación del recurso bosque, por mujeres en San Isidro Buen Suceso, Tlaxcala.
Provedor de dados: 32
Autores: Romo Evaristo, Marisol.
En la actualidad la situación de degradación de los recursos naturales, en especial el recurso bosque, ocasiona la pérdida tanto de identidad de la población que dependen de estos recursos, como de la misma flora y fauna del lugar, además que la introducción de la tecnología moderna y las formas de producción añadidos con el consumismo, han favorecido la destrucción del ambiente natural, siendo la sociedad humana una de las principales causas de dicha degradación. Aunado a ello, desde los 80s, se enfatizó que las mujeres fueron las principales víctimas del deterioro ambiental, además de catalogarlas como adaptadas para soportar catástrofes como las sequias, y se consideraban víctimas del deterioro ambiental, de los procesos científicos y de desarrollo mal...

Variación ecológica, morfológica y química: atributos clave para el aprovechamiento y conservación de Jatropha sp.
Provedor de dados: 32
Autores: Hernández Nicolás, Nancy Yazmin.
En México se consignan 45 especies para el género Jatropha (Euphorbiaceae). La Reserva de las Biosfera de Tehuacán-Cuicatlán concentra riqueza genética y endemismo para este género, que proporciona alimento, medicina y energía a los habitantes, pero falta información sobre la distribución, ecología y aprovechamiento de las especies. Esta tesis se organizó en tres capítulos. En el primero se precisaron taxonómicamente las especies de Jatropha, se diferenciaron las Unidades Ambientales (UA) en las que habitan, se valoró el estado de conservación de sus hábitats y se calificó la vulnerabilidad de sus poblaciones; en el segundo capítulo, se verificó la variación morfológica intra e interespecífica; y,  en el último, se caracterizó el aprovechamiento...

Análisis de la variación infraespecífica de Vanilla insignis Ames bajo el enfoque de recursos genéticos.
Provedor de dados: 32
Autores: Hernández Silva, Néstor.
En la actualidad los efectos negativos de las interacciones bióticas y abióticas dentro del cultivo de Vanilla planifolia han devastado plantaciones de este recurso en todo el mundo. La generación de estrategias para su conservación y mejoramiento requiere del conocimiento de la variación que el género Vanilla alberga. Vanilla insignis es una especie silvestre genéticamente relacionada, con características agronómicas sobresalientes dentro del pool genético secundario de V. planifolia, particularmente en la resistencia a factores climáticos y patógenos. Por tal razón, se planteó conocer la variación infraespecífica de V. insignis por medio de la caracterización morfológica y molecular de poblaciones de V. insignis del estado de Quintana Roo, México.

El programa de pago de servicio ambiental hidrológico (PSAH) como una estrategia de conservación de recursos naturales y sensibilización ambiental de la región Izta-Popo
Provedor de dados: 32
Autores: Martínez Cruz, Diego Armando.
Los bosques de la región Izta-Popo del estado de Puebla son importantes para mantener los procesos del ciclo hidrológico, del cual depende el abastecimiento de agua para las comunidades locales y para la ciudad de Puebla. Para evitar la pérdida y deterioro de estos bosques en la región, la Comisión Nacional Forestal (CONAFOR) ha ejecutado desde hace 5 años el programa de Pago por Servicios Hidrológicos (PSAH). Si se toma en cuenta que el éxito de cualquier estrategia de conservación depende en gran medida de su aprobación por parte de las comunidades poseedoras de los recursos, el conocer la percepción y actitudes respecto a temas de conservación dará elementos para revisar la pertinencia, limitaciones y efectos positivos del programa en la región. En este...

Provedor de dados: 32
Autores: Ramírez Jaspeado, Araceli.
El maíz es el cultivo más importante de México cuya superficie de siembra es de 8 millones de hectáreas con un rendimiento promedio de 3 ton/ha. Su aprovechamiento involucra los granos, tallos, espigas, raíces, olote y brácteas (“hoja para tamal”) utilizados para diversos propósitos en la alimentación humana, animal, medicinal e industrial. Se ha considerado que la principal forma de consumo del maíz es a través de la tortilla, donde, alrededor de 12.3 millones de toneladas de maíz se consumen en esta forma. En este sentido, los maíces mejorados han sido esenciales para dicho propósito, sin embargo, el uso de los maíces nativos o criollos, también ha sido de gran importancia ya que son un reservorio de la variabilidad genética y han sido la base de la...

In recent years, few if any community conserved areas (CCAs) in the Pacific island region have been regarded as being successful. However, as success is rarely defined, what constitutes &amp;#8220;success&amp;#8221; is not clear. This paper reports an investigation into the way &amp;#8220;outsiders&amp;#8221; perceive success in Pacific island CCAs. An exploratory survey revealed six umbrella themes of success: the locus of control; local benefits; resource aspects; management; external stakeholder involvement; and sustainability. Multivariate analysis distinguished two groups, a Big picture group and a Locally focused group. These differ in how they define success, as well as their organizational alignment. The Big picture group, largely from funder...

There is consensus that payments for biodiversity services are a promising conservation tool, yet the implementation of applied schemes has been lagging behind. This paper explores some reasons why potential biodiversity buyers may hesitate. It describes the case of an unsuccessful attempt to establish a community conservation concession in the village of Setulang (East Kalimantan, Indonesia) to safeguard a biologically valuable area from predatory logging. Potential biodiversity donors did not engage in this payments-for-environmental-services scheme mainly because of their limited time horizon and uneasiness about the conditionality principle. Other complicating factors included overlapping land claims, and the diagnosis of the externality at hand. We...

Increasingly, the world is becoming socioeconomically and environmentally connected, but many studies have focused on human-environment interactions within a particular area. Although some studies have considered the impacts of external factors, there is little research on multiple reciprocal socioeconomic and environmental interactions between a focal area and other areas. Here we address this important knowledge gap by applying the new integrated framework of telecouplings (socioeconomic and environmental interactions between two or more areas over distances). Results show that even a protected area - i.e., the Wolong Nature Reserve for giant pandas in southwest China - has multiple telecoupling processes with the rest of the world; these include panda...

Natural resource agencies worldwide must develop species recovery plans that specify threats, propose targets required for recovery, and evaluate the extent to which habitat alteration and restoration may influence species decline and recovery. To evaluate the impacts of proposed habitat alterations on species of conservation concern, standardized protocols may be adopted even when supporting data are scarce. For example, a habitat matrix was developed by the National Marine Fisheries Service (NMFS) to guide consultations under the Endangered Species Act for actions that may affect the functioning of the freshwater habitat used by several federally listed salmonid species. The habitat matrix has also been advocated as a tool for recovery planning by...

Priority Areas for Establishing National Forests in the Brazilian Amazon
Provedor de dados: 7
Brazil will benefit if it gains control of its vast Amazonian timber resources. Without immediate planning, the fate of much of the Amazon will be decided by predatory and largely unregulated timber interests. Logging in the Amazon is a transient process of natural resource mining. Older logging frontiers are being exhausted of timber resources and will face severe wood shortages within 5 yr. The Brazilian government can avoid the continued repetition of this process in frontier areas by establishing a network of National Forests (Florestas Nacionais or Flonas) to stabilize the timber industry and simultaneously protect large tracts of forest. Flonas currently comprise less than 2% of the Brazilian Amazon (83,000 km2). If all these forests were used for...

The term socio-ecological production landscapes (SEPLs) has recently gained currency in conservation circles because of a recognized need to look beyond protected areas to the management of human-influenced landscapes and ecosystems. We have drawn on a variety of case studies from Asia and other parts of the world to understand the underlying driving forces that have led to the need for greater awareness and sustainable management of SEPLs. We have analyzed the drivers of these changes from socio-political, legal, economic, and socio-cultural perspectives. The analysis shows that SEPLs contribute to local, national, and global economies, and their production and harvesting processes are subject to external demands and pressures. Policy makers should...

Nature vs. Nurture: the Making of the Montado Ecosystem
Provedor de dados: 7
The southern Iberian Peninsula is dominated by a savannah-like ecosystem, the montado, which is a typically Mediterranean cultural adaptation to generally poor productive areas. Montados are exploited for three main uses: forestry, agriculture, and extensive grazing, in proportions that vary according to local conditions (more or less productive land) and historical circumstances. Because these ecosystems occur over a large geographic area (they occupy some 6 million ha), biodiversity would be expected to vary among montados. However, differences in management practices may also influence species distribution. In this paper, we investigate differences in plant and bird species diversity among 60 montados distributed all across southern Portugal. The...

Monitoring the influence of human actions on flagship species is an important part of conserving biodiversity, because the information gained is crucial for the development and adaptation of conservation management plans. On the Masoala Peninsula in Madagascar, we are monitoring the two largest prosimian species, Eulemur fulvus albifrons and Varecia variegata rubra, at disturbed and undisturbed forest sites to determine if extraction of forest resources has a significant impact on the population viability of these species. To test the sensitivity of lemur species to routine extraction of natural resources by local villagers, we compared population demography and density for both species across six study sites, using a new census technique. Three of the...

The Palouse region of southeastern Washington State and an adjacent portion of northern Idaho is a working landscape dominated by agricultural production, with less than 1% of the original bunchgrass prairie remaining.  Government agencies and conservation groups have begun efforts to conserve Palouse prairie remnants, but they lack critical information about attitudes and perceptions among local landowners toward biological conservation.  Knowledge about the location and condition of native biological communities also remains sparse.  Using a bioregional approach, we integrated data collected through biological surveys and social interviews to investigate relationships between biologically and socially meaningful aspects of the landscape.  We combined GIS...

This article addresses the question, to what extent and under which conditions nontimber forest product (NTFP) trade leads to both livelihood improvement and forest conservation. We based the analysis on a standardized expert-judgment assessment of the livelihood and environmental outcomes of 55 cases of NTFP trade from Asia, Africa, and Latin America. The results show that NTFP trade benefits several components of peoples' livelihoods, but may increase inequality between households. Involvement of women in the production-to-consumption system (PCS) tends to have a positive impact on intrahousehold equity. In 80% of the cases, the commercial production of NTFPs does not enable people to make financial investments to increase quality and quantity of...

Commercialization of non-timber forest products (NTFPs) has been widely promoted as a means of sustainably developing tropical forest resources, in a way that promotes forest conservation while supporting rural livelihoods. However, in practice, NTFP commercialization has often failed to deliver the expected benefits. Progress in analyzing the causes of such failure has been hindered by the lack of a suitable framework for the analysis of NTFP case studies, and by the lack of predictive theory. We address these needs by developing a probabilistic model based on a livelihood framework, enabling the impact of NTFP commercialization on livelihoods to be predicted. The framework considers five types of capital asset needed to support livelihoods: natural,...

At a global scale, aquatic ecosystems are being altered by human activities at a greater rate than at any other time in history. In recent years, grassroots efforts have generated interest in the restoration of degraded or destroyed aquatic habitats, especially small wetlands and streams where such projects are feasible with local resources. We present ecological management lessons learned from 17 years of monitoring the fish community response to the channel relocation and reach-level restoration of Juday Creek, a 3rd-order tributary of the St. Joseph River in Indiana, USA. The project was designed to increase habitat complexity, reverse the effects of accumulated fine sediment (&amp;#60; 2 mm diameter), and mitigate for the impacts of a new golf course...

As a response to widespread concern about the state of marine ecosystems and the perceived failure of existing policies, many organizations are developing market-based instruments that promote sustainability. Eco-standards such as shopping guides, eco-labels, and stewardship certifications are now commonplace. However, in many cultures dietary guidelines have existed for thousands of years, and anthropologists have argued that such dietary rules emerged to reduce environmental impacts by encouraging exploitation of productive species, increasing ecological efficiency, or decreasing harvest of apex predators. We explored some of the environmental consequences for marine and aquatic systems of one of the more familiar ancient dietary traditions, keeping...

As a follow-up to the observations of Charles Robertson from 1884 to 1916, we revisited the Carlinville, Illinois, area between 18 August 1970 and 13 September1972 to sample and identify bee species (Hymenoptera: Apoidea). We concentrated on collecting nonparasitic bees (and excluded Apis and Bombus) visiting 24 plant species that bloomed at various times of the year, and upon which Charles Robertson found many bee species. For example, we collected most intensively on spring-blooming Claytonia virginica and fall-blooming Aster pilosus, upon which Robertson reported 58 and 90 bee visitors, respectively. Bees were also collected on an opportunistic basis at some other plants. We updated the species names used by Robertson for revisions and synonymies. This...

Are Direct Payments for Environmental Services Spelling Doom for Sustainable Forest Management in the Tropics?
Provedor de dados: 7
Autores: Wunder, Sven; Center for International Forestry Research; s.wunder@cgiar.org.
Over the past several decades, significant donor funding has been directed to sustainable forest management in the tropics, in the hope of combining forest conservation with economic gains through sustainable use. To date, this approach has produced only modest results in terms of changed silvicultural and land-use practices in this area. Direct payments for environmental services (PES) have been suggested as a promising alternative but still remain widely untested in the tropics. This paper first provides a conceptual assessment of PES, comparing the main features of this practice with those of other conservation instruments. Second, the paper discusses a series of critical questions that have been raised about both the environmental and livelihood...

Faced with fiscal constraints and enormous population pressures, 80% of Chinese nature reserves have employed ecotourism as a support and development strategy. Assessing the actual effects of ecotourism at a nature reserve that has a relatively long history of ecotourism development experience may be instructive for other reserves. Therefore, we take Changbai Mountain Biosphere Reserve (CMBR) in northeastern China as a case study, for it is one of the pioneers in embracing ecotourism in China. Personal interviews and informal group discussions were employed to understand local residents&amp;#8217; attitudes toward conservation. Factors affecting their attitudes were then analyzed using logistic regression. Results indicate that attitudes held by most...

Relationships between humans and nature take multiple forms. This is a fundamental issue in conservation but one that is often neglected, leading to poor conservation outcomes. It is thus imperative that we come to understand better the complex relationships between humans and nature. To do so, we need to examine &amp;#8220;nature&amp;#8221; and the often assumed dichotomy between humans and nature. We conducted a qualitative social research inquiry to explore the societal relationships with nature in the Cape Horn Biosphere Reserve in Chile. From the results, we developed a framework that illustrates how different &amp;#8220;natures&amp;#8221; are created in the three-way relationship among the individual, society, and the physical world.

Causes and Extent of Declines among Native North American Invertebrate Pollinators: Detection, Evidence, and Consequences
Provedor de dados: 7
Autores: Cane, James H; USDA-ARS; jcane@biology.usu.edu; Tepedino, Vincent J; USDA-ARS; andrena@biology.usu.edu.
Ecosystem health and agricultural wealth in North America depend on a particular invertebrate fauna to deliver pollination services. Extensive losses in pollinator guilds and communities can disrupt ecosystem integrity, a circumstance that today forces most farmers to rely on honey bees for much fruit and seed production. Are North America's invertebrate pollinator faunas already widely diminished or currently threatened by human activities? How would we know, what are the spatiotemporal scales for detection, and which anthropogenic factors are responsible? Answers to these questions were considered by participants in a workshop sponsored by the National Center for Ecological Analysis and Synthesis in October of 1999, and these questions form the nucleus...

Conservation in densely settled biodiversity hotspots often requires setting up reserve networks that maintain sufficient contiguous habitat to support viable species populations. Because it is difficult to secure landholder compliance with a tightly constrained reserve network design, attention has shifted to voluntary incentive mechanisms, such as purchase of conservation easements by reverse auction or through a fixed-price offer.  These mechanisms carry potential advantages of transparency, simplicity, and low cost. However, uncoordinated individual response to these incentives has been assumed incompatible with the conservation goal of viability, which depends on contiguous habitat and biodiversity representation. We model such incentives for southern...

Over the past 40 years, Nepal has become renowned for its community-based forestry policies, initiatives, and institutions, characterized by local autonomy in decisions about forest management and use and a gradual shift toward more inclusive national policy processes. In recent years, the government, international nongovernmental organizations (NGOs), donors, and some civil society organizations have instigated policy and piloting initiatives for an international climate change mitigation scheme known as &amp;#8220;reducing emissions from deforestation and forest degradation and enhancement of forest carbon stocks in developing countries&amp;#8221; (REDD+).

Despite their dual importance in the assessment of endangered/threatened species, there have been few attempts to integrate traditional ecological knowledge (TEK) and evolutionary biology knowledge (EBK) at the population level. We contrasted long-term aboriginal TEK with previously obtained EBK in the context of seasonal migratory habits and population biology of a salmonid fish, brook charr, (Salvelinus fontinalis) inhabiting a large, remote postglacial lake. Compilation of TEK spanning four decades involved analytical workshops, semidirective interviews, and collaborative fieldwork with local aboriginal informants and fishing guides. We found that TEK complemented EBK of brook charr by providing concordant and additional information about (1) population...

Scale is a concept that transcends disciplinary boundaries. In ecology and geography, scale is usually defined in terms of spatial and temporal dimensions. Sociological scale also incorporates space and time, but adds ideas about representation and organization. Although spatial and temporal location determine the context for social and ecological dynamics, social-ecological interactions can create dynamic feedback loops in which humans both influence and are influenced by ecosystem processes. We hypothesize that many of the problems encountered by societies in managing natural resources arise because of a mismatch between the scale of management and the scale(s) of the ecological  processes being managed. We use examples from southern Africa and the...

Wild meat is critical for the food security and income of millions of people, especially for poor rural households. Its role as a primary source of macronutrients worldwide has been recognized, but there have been few attempts to evaluate the contribution of bushmeat consumption to micronutrient intake. This is so particularly in the context of nutritional transitions induced by modernization and globalization. Here, we calculated the role of bushmeat as a source of micronutrients in the diets of urban and peri-urban inhabitants within the Tres Fronteras (Peru, Brazil, Colombia) region in the Amazon. We gathered food intake data from 35 households using 3-day 24-h food recalls combined with food weighing. Additionally, we interviewed 105 households on food...

Intact migratory routes are critical for the stability of forest-dwelling, neotropical, migratory bird populations, and mortality along migratory pathways may be significant. Yet we know almost nothing about the geography of available stopovers or the possible migratory pathways that connect optimal stopovers. We undertake a spatial analysis of stopover habitat availability and then model potential migratory pathways between optimal stopovers in the eastern United States. Using models of fixed orientation and fixed nightly flight distance between stopovers during spring migration, we explore whether a simple endogenous migratory program is sufficient to ensure successful migration across the modern landscape.  Our model runs suggest that the modern...

Autores: Pittock, Jamie; Australian National University; jamie.pittock@anu.edu.au.
Even in the absence of climate change, freshwater ecosystems and the resources they provide for people are under great pressure because of increasing demand for water and declines in water quality. The imminent onset of climate change will exacerbate these impacts, placing even greater pressure on already stressed resources and regions. A plethora of national climate change policies have been adopted that emphasize structural adjustment in the energy sector and increasing carbon sinks. To date, most public debate on water has focused on the direct impacts of climate change on hydrology. However, there is growing evidence that climate change policies themselves may have substantial additional and negative impacts on freshwater resources and ecosystems and...

Invasive species (IS) threaten biodiversity and ecosystem functioning. To achieve landscape-scale reductions in IS and the associated gains for biodiversity, IS control efforts must be expanded across private lands. Enhancing IS control across private lands requires an understanding of the factors that motivate residents to engage or prohibit residents from engaging in efforts to control IS. Drawing from the collective interest model and literature, we sought to understand how a wide range of interpersonal, intrapersonal, and contextual factors might influence resident action around combating the invasive tree albizia (Falcataria moluccana), in the Puna District of Hawai&amp;#699;i.

Interlocking panarchies in multi-use boreal forests in Sweden
Provedor de dados: 7
This paper uses northern Sweden as a case study of a multi-use social-ecological system, in which forestry and reindeer husbandry interact as different land use forms in the same area. We aim to describe the timeline of main events that have influenced resource use in northern Sweden, that is, to attempt a historical profiling of the system, and to discuss these trends in the system in terms of adaptive cycles and resilience. The study shows that key political decisions have created strong path dependencies and a situation in which forestry today is characterized by low flexibility and low resilience due to the highly optimized harvesting of tree resources. Since forestry is the overwhelmingly strongest actor, trends in forestry from the mid-19th century...

It is just not fair: the Endangered Species Act in the United States and Ontario
Provedor de dados: 7
Autores: Olive, Andrea; University of Toronto; andrea.olive@utoronto.ca.
The United States and the Canadian province of Ontario have enacted endangered species laws that regulate private land. The rationale for this is that the vast majority of endangered species in the two countries rely on private lands for survival. However, from a landowner perspective the law is deemed unfair. This paper presents analysis from 141 interviews with landowners in three U.S. states and Ontario. In recognition of distributive justice claims, both the U.S. government and the Ontario government have enacted programs aimed at increasing financial incentives for participation and compliance with the law. However, the law is still perceived as unfair. The central argument of this paper is that future amendments and new policies for endangered...

We review characteristics of birds in boreal forests in the context of their ecological sustainability under both natural and anthropogenic disturbances. We identify the underlying ecological factors associated with boreal bird populations and their variability, review the interactions between boreal bird populations and disturbance, and describe some tools on how boreal bird populations may be conserved in the future. The boreal system has historically been an area with extensive disturbance such as fire, insect outbreaks, and wind. In addition, the boreal system is vulnerable to global climate change as well as increasing pressure on forest and water resources. Current knowledge indicates that birds play an important role in boreal forests, and...

Evaluation, the process of assessing the effectiveness of programs and activities, has gained increasing attention in the conservation sector as programs seek to account for investments, measure their impacts, and adapt interventions to improve future outcomes.    We conducted a country-wide evaluation of terrestrial-based conservation programs in Samoa. Though rarely applied, the benefit of evaluating multiple projects at once is that it highlights factors which are persistent and influential across the entire conservation sector. We found mixed success in achieving goals among conservation programs; yet this result is surrounded by uncertainty because of the quality of existing evidence on project outcomes.  We explore the role of different components of...

Within the boreal zone, there are about 50 native mammalian herbivore species that belong to the orders Artiodactyla, Rodentia, and Lagomorpha. Of these species, 31 occur in the Nearctic and 24  in the Palaearctic. Only six species occur in both regions. Species of the family Cervidae have probably been, and still are, the most important group for man, as they provide both meat and hides. Pelts from squirrels, muskrats, and hares were commercially harvested at the beginning of the century, but have less value today. The semi-domestic reindeer in the Palaearctic produces meat and hides on a commercial basis. It is also used for milking, to a limited extent, as is the semi-domestic moose in Russia. The Siberian musk deer is used for its musk and is raised in...

We applied an integrative framework to illuminate and discuss the complexities of exurbanization in Macon County, North Carolina.  The case of Macon County, North Carolina, highlights the complexity involved in addressing issues of exurbanization in the Southern Appalachian region. Exurbanization, the process by which urban residents move into rural areas in search of unique natural amenities and idealized lifestyles, can often have a dramatic impact on the local economy, culture, and environment. Within Macon County, complex debates and tensions among multiple stakeholders struggle to address local residential development. How can better problem definition benefit rural communities in addressing exurbanization pressures and effects? We asserted that a key...

Current ecological, economic, and social conditions present unique challenges to natural resource managers seeking to maintain the resilience of disturbance-dependent ecosystems, such as oak (Quercus spp.) forests.  Oak-dominated ecosystems throughout the U.S. have historically been perpetuated through periodic disturbance, such as fire, but more recently show decline given shifting disturbance regimes associated with human land management decisions.  We characterized the state of the social-ecological oak forest ecosystem in the midwestern U.S. through the perspectives of 32 natural resource professionals.  Data from interviews with these change agents provided an integrative understanding of key system components, cross-scale interactions, dependencies,...

Exploring the Role of Private Wildlife Ranching as a Conservation Tool in South Africa: Stakeholder Perspectives
Provedor de dados: 7
Autores: Cousins, Jenny A; University of Manchester; Jenny.Cousins@postgrad.manchester.ac.uk; Sadler, Jon P; University of Birmingham;; Evans, James; University of Manchester;.
Rich in biological diversity, South Africa&amp;#8217;s natural habitats are internationally recognized as a conservation priority. Biodiversity loss continues, however, and limited scope to enlarge the state-protected areas, combined with funding shortages for public parks, means that conservationists are increasingly turning to private landowners for solutions. The recent boom in privately owned wildlife ranches in South Africa has the potential to contribute to conservation in South Africa. This paper explores the benefits, limitations, and challenges of private wildlife ranching as a tool for conservation in South Africa through interviews with key stakeholders working within conservation and wildlife ranching, and through case studies of threatened...

Conserving wildlife while simultaneously meeting the resource needs of a growing human population is a major sustainability challenge. As such, using combined social and environmental perspectives to understand how people and wildlife are interlinked, together with the mechanisms that may weaken or strengthen those linkages, is of utmost importance. However, such integrated information is lacking. To help fill this information gap, we describe an integrated coupled human and natural systems (CHANS) approach for analyzing the patterns, causes, and consequences of changes in wildlife population and habitat, human population and land use, and their interactions. Using this approach, we synthesize research in two sites, Wolong Nature Reserve in China and...

We reviewed construct validity in perception-based methods assessing status and/or trend of forest condition as applied in 19 empirical studies that evaluated the conservation impact of popular participation in forest management. Perception-based methods focus on eliciting peoples&amp;#8217; assessment of the status and/or trend in forest condition or indicators of forest condition through interviews, surveys, or participatory rural appraisal techniques. We found that individual studies generally did not attend to the issue of construct validity in relation to each particular approach to perception-based assessment of status and/or trend in forest condition. Furthermore, the studies provided very little documentation of the construct validity of the...

Fluctuations in population size can have a profound impact on effective population size and the maintenance of genetic variation within a population. A number of tests based on microsatellite data have been developed for the detection of bottleneck events in a population's past. In this paper, we search for signs of a bottleneck in microsatellite data on the Scandinavian lynx (Lynx lynx) population. This population was hunted to the brink of extinction, with fewer than 100 animals (one estimate was as low as 30 individuals) remaining in the late 1920s. Protection allowed recovery of the population, which currently numbers about 2000 adults. Despite this pronounced demographic bottleneck (more than 95% of the population was killed), we could find no...

The role of game mammals as bushmeat In the Caatinga, northeast Brazil
Provedor de dados: 7
Although the use of wild mammals as a source of food has been better studied in tropical forest environments, their importance as a source of protein for human communities in semiarid environments is little known. In the latter, the availability of wild animal meat is limited in comparison to other environments. In the semiarid regions of northeastern Brazil, hunting wild mammals for their meat is traditional, playing a crucial role in the livelihoods and food security of various rural and urban communities, especially during the annual drought seasons. In this study, we investigated the role of wild mammals as bushmeat in 10 communities within the Caatinga biome in northeast Brazil. We used key-informant interviews, household surveys, and questionnaires...

Over the past decade, various strategies have emerged to address critical habitat losses through agricultural expansion. The promotion of shade-grown, premium-priced coffee has been highlighted as one alternative. Our research, based on interviews with farmers in Chiapas, disputes some of the assumptions made by shade coffee campaigners. Results revealed a predisposition to converting forest to shade coffee production due to the socioeconomic challenges farmers face and the potential for increasing incomes. To ensure that their well-being is improved at the same time as reducing environmental impacts, there is clearly a need to provide more detailed information on who is responsible for enforcing certification criteria and how this should take place.

North American Dipteran Pollinators: Assessing Their Value and Conservation Status
Provedor de dados: 7
Autores: Kearns, Carol Ann; University of Colorado at Boulder; kearnsca@rtt.colorado.edu.
Recent attention to pollinator declines has focused largely on bees and vertebrates. However, few pollination systems are obligate, and pollinators that complement the role of bees may respond differently to environmental disturbance. The conservation status of North American fly pollinators remains undocumented. In this paper, methods for monitoring shifts in dipteran pollinator abundance are discussed. The need for further basic research into pollination by flies is addressed, and the significance of dipteran conservation is considered.

Leadership is often assumed, intuitively, to be an important driver of sustainable development. To understand how leadership is conceptualized and analyzed in the environmental sciences and to discover what this research says about leadership outcomes, we conducted a review of environmental leadership research over the last 10 years. We found that much of the environmental leadership literature focuses on a few key individuals and desirable leadership competencies. The literature also reports that leadership is one of the most important of a number of factors contributing to effective environmental governance. Only a subset of the literature highlights interacting sources of leadership, disaggregates leadership outcomes, or evaluates leadership processes...

There are many recommendations for environmental management practices to adopt more holistic or systems-based approaches and to strengthen stakeholder participation. However, management practices do not always match or achieve these ideals. We explore why theory may not be reflected by practice by exploring experiences of projects seeking to implement the ecosystem approach, a concept that entails participatory holistic management. A qualitative inductive approach was used to understand the processes, achievements, and challenges faced by 16 projects across the British Isles. Many projects made significant progress toward their goals, yet failed to achieve fully participatory holistic management. Many of the challenges that contributed to this failure can...

Autores: Ricketts, Taylor; World Wildlife Fund; taylor.ricketts@wwfus.org; Imhoff, Marc; NASA's Goddard Space Flight Center; mimhoff@LTPmail.gsfc.nasa.gov.
Urbanization and agriculture are two of the most important threats to biodiversity worldwide. The intensities of these land-use phenomena, however, as well as levels of biodiversity itself, differ widely among regions. Thus, there is a need to develop a quick but rigorous method of identifying where high levels of human threats and biodiversity coincide. These areas are clear priorities for biodiversity conservation. In this study, we combine distribution data for eight major plant and animal taxa (comprising over 20,000 species) with remotely sensed measures of urban and agricultural land use to assess conservation priorities among 76 terrestrial ecoregions in North America. We combine the species data into overall indices of richness and endemism. We...

Emerging infectious diseases are a growing concern in wildlife conservation. Documenting outbreak patterns and determining the ecological drivers of transmission risk are fundamental to predicting disease spread and assessing potential impacts on population viability. However, evaluating disease in wildlife populations requires expansive surveillance networks that often do not exist in remote and developing areas. Here, we describe the results of a community-based research initiative conducted in collaboration with indigenous harvesters, the Inuit, in response to a new series of Avian Cholera outbreaks affecting Common Eiders (Somateria mollissima) and other comingling species in the Canadian Arctic. Avian Cholera is a virulent disease of birds caused by...

Despite heavy pressure and disturbance, state property regimes have stemmed deforestation within protected areas of the West Mengo region of Uganda for over 50 yr. In this manuscript, we reconstruct the process of creation and maintenance of forest reserve boundaries in the West Mengo region of Uganda to identify why these boundaries have largely remained stable over the long term under conditions in which they may be predicted to fail. The dramatic boundary stability in West Mengo we attribute to key aspects of institutional design and enforcement of boundaries.

Wild harvesting has taken place over millennia in Africa. However urbanization and cash economies have effectively altered harvesting from being cultural, traditional, and subsistence activities that are part of a rural norm, to being a subculture of commonly illicit activities located primarily within the urban, cash-based, informal economy. This paper focuses on Cape Town, South Africa where high levels of poverty and extensive population growth have led to a rapidly growing informal industry based on the cultural, subsistence, and entrepreneurial harvesting and consumption of products obtained from the local natural environment.  Through a process of literature reviews, database analysis, and key informant interviews, a compendium of harvested species...

Conservation and Unscripted Development:  Proximity to Park Associated with Development and Financial Diversity
Provedor de dados: 7
Autores: Baird, Timothy D.; Virginia Tech; tbaird@vt.edu.
Decades of research on the social dynamics of biodiversity conservation has shown that parks and protected areas have added hardship to rural communities throughout much of the developing world.  Nonetheless, some recent studies have found evidence of poverty alleviation near protected areas.  To build on these conflicting accounts, I use a comparative, mixed-methods design to examine opportunistic, unplanned, i.e., unscripted, development in indigenous communities near Tarangire National Park (TNP) in northern Tanzania.  I ask the questions: (1) How is proximity to TNP related to community-level infrastructural development?  (2) How has the process of development changed over time? and (3) How is proximity to TNP related to infrastructure-related social...

Conservation biology and environmental anthropology are disciplines that are both concerned with the identification and preservation of diversity, in one case biological and in the other cultural. Both conservation biology and the study of traditional ecoloigcal knowledge function at the nexus of the social and natural worlds, yet historically there have been major impediments to integrating the two. Here we identify linguistic, cultural, and epistemological barriers between the two disciplines. We argue that the two disciplines are uniquely positioned to inform each other and to provide critical insights and new perspectives on the way these sciences are practiced. We conclude by synthesizing common themes found in conservation success stories, and by...

The reintroduction of large mammals is often considered a priority conservation action in highly industrialized countries in which many of these species have been depleted. However, species reintroduction after decades of absence may involve important risks for human activities and ecological communities, such as favoring the spread of diseases. An example of a potentially troublesome reintroduction is the wild boar, which may act as a reservoir of diseases, e.g., classical swine fever, and cause high economic losses, and has become a species of concern in several European countries for both ecological and recreational reasons. Failure to prevent the disease consequences of species restoration can negate its conservation benefits. Here we evaluated the...

Members of the public participate in scientific research in many different contexts, stemming from traditions as varied as participatory action research and citizen science. Particularly in conservation and natural resource management contexts, where research often addresses complex social&amp;#8211;ecological questions, the emphasis on and nature of this participation can significantly affect both the way that projects are designed and the outcomes that projects achieve. We review and integrate recent work in these and other fields, which has converged such that we propose the term public participation in scientific research (PPSR) to discuss initiatives from diverse fields and traditions.

Habitat Fragmentation and Native Bees: a Premature Verdict?
Provedor de dados: 7
Autores: Cane, James H; USDA-ARS; jcane@biology.usu.edu.
Few studies directly address the consequences of habitat fragmentation for communities of pollinating insects, particularly for the key pollinator group, bees (Hymenoptera: Apiformes). Bees typically live in habitats where nesting substrates and bloom are patchily distributed and spatially dissociated. Bee studies have all defined habitat fragments as remnant patches of floral hosts or forests, overlooking the nesting needs of bees. Several authors conclude that habitat fragmentation is broadly deleterious, but their own data show that some native species proliferate in sampled fragments. Other studies report greater densities and comparable diversities of native bees at flowers in some fragment size classes relative to undisrupted habitats, but find...

Systematic planning for biodiversity conservation is being conducted at scales ranging from global to national to regional. The prevailing planning paradigm is to identify the minimum land allocations needed to reach specified conservation targets or maximize the amount of conservation accomplished under an area or budget constraint. We propose a more general formulation for setting conservation priorities that involves goal setting, assessing the current conservation system, developing a scenario of future biodiversity given the current conservation system, and allocating available conservation funds to alter that scenario so as to maximize future biodiversity. Under this new formulation for setting conservation priorities, the value of a site depends on...

Forest Landscape Restoration (FLR) involves the ecological restoration of degraded forest landscapes, with the aim of benefiting both biodiversity and human well-being. We first identify four fundamental principles of FLR, based on previous definitions. We then critically evaluate the application of these principles in practice, based on the experience gained during an international, collaborative research project conducted in six dry forest landscapes of Latin America. Research highlighted the potential for FLR; tree species of high socioeconomic value were identified in all study areas, and strong dependence of local communities on forest resources was widely encountered, particularly for fuelwood. We demonstrated that FLR can be achieved through both...

Many protected areas (PAs) have followed the conventional and exclusionary approach applied at Yellowstone in 1872. As such, many parks have failed to fully integrate other important factors, such as social, cultural, and political issues. In some cases, this has triggered adverse social impacts on local communities, disrupting their traditional ways of living and limiting their control of and access to natural resources. Such an outcome can undermine protection policies through conflicts between park managers and local communities. The success of conservation strategies through protected areas may lie in the ability of managers to reconcile biodiversity conservation goals with social and economic issues and to promote greater compliance of local...

In the drylands of northern Kenya, as elsewhere in Africa, traditional pastoralist social-ecological systems are undergoing profound transformations. Diminishing resource availability, changing social values and governance systems, and new resource management institutions challenge the capacity of communities for effective common pool resource management.  Individuals&amp;#8217; values and environmental perceptions play a substantial role in decision making regarding resource use and management. Additionally, social capital within communities can influence cooperative and adaptive resource management. We studied five Laikipia Maasai communities in Kenya, which share a common natural environment, history, and political organization.  We surveyed...

Effects of disturbances generated by different management strategies on the vegetation strata of Nothofagus antarctica forests of Chubut, Argentina
Provedor de dados: 67
Autores: Gönc,Romina L.; Casaux,Ricardo J.; Szulkin-Dolhatz,Daniel.
Nothofagus antarctica is a species of the Andean-Patagonian forest with a wide distribution from the north of Neuquén to Tierra del Fuego. Although the N. antarctica forests are of great economic importance for the region, they are intensely affected nowadays by human activities such as grazing, firewood extraction, conversion into pastures and the replacement by coniferous plantations. These activities produce changes in the N. antarctica forest, mainly by the alteration of its original structure affecting the performance of the ecosystem as a whole, resulting in the loss of biodiversity. Since July 2008 up to May 2010 in the northwest of Chubut, Patagonia, we analyzed the effect of disturbances associated with different management strategies on species...

Invasive alien species management in Patagonia, Argentina: Prioritization, achievements and science-policy integration challenges identified by the National Parks Administration: Invasive alien species are a threat to biodiversity. Management options encompass prevention, early detection, eradication, control, exclusion and even"no action." More technical information is needed to achieve complex management actions successfully. In addition, managers and researchers address the problem with different approaches. Managers seek to prioritize management actions, and for researchers, these species are an opportunity to study basic and/or theoretical aspects, but not always applied to management. However, the management strategies offer a unique opportunity for...

Space use by wild Greater Rhea (Rhea americana) in a relict grassland of central Argentina during the non-breeding season
Provedor de dados: 68
Autores: Juan,Ernesto E.; Bazzano,Gisela; Navarro,Joaquín L.; Martella,Mónica B.
To determine movement patterns and home range of wild Greater Rhea (Rhea americana), two subadult males were radio-tracked during the non-breeding season in a relict grassland of San Luis Province, Argentina. The average home range was 452.8 ha, the average daily distance travelled was 1.08 km/day, and the maximum distance from the capture/release site was 13.66 km. Rheas showed differences in habitat types used throughout the day. Grasslands were more frequently used early in the morning and late in the afternoon, whereas cultivated pastures (Medicago sativa) were used at noon. Although data is considered preliminary due to the small sample size, the importance of this study is here emphasized because it provides the first records of the spatial ecology...

First record of breeding of the Ornate Hawk-Eagle (Spizaetus ornatus) in Southern Brazil
Provedor de dados: 68
Autores: Joenck,Cristian M; Zilio,Felipe; de Mendonça-Lima,André.
We provide the first record of breeding of the Ornate Hawk-Eagle (Spizaetus ornatus) for southern Brazil. In September 2005 a nest was found inside the reservoir of the Barra Grande Hydroelectric Power Station, northern Rio Grande do Sul. On the nest there was a nestling around two months old. Based in prey remains collected on the nest, birds were the main item in diet. This is an endangered species in the Atlantic Rain Forest biome in Brazil and the presence of the nest and nestling offer evidence of reproduction in Southern Brazil.

Mortality and injuries of Olrog's Gull (Larus atlanticus) individuals associated with sport fishing activities in Mar Chiquita coastal lagoon, Buenos Aires Province
Provedor de dados: 68
Autores: Berón,M. Paula; Favero,Marco.
The Olrog's Gull (Larus atlanticus) is an endemic species of the Atlantic coasts of southern South America and is considered vulnerable to extinction. Olrog's Gull individuals of different age classes die in Mar Chiquita coastal lagoon, Buenos Aires Province, while interacting with sport fisheries. Due to its restricted distributional range and their scarce populations, a slight increase in mortality rates may easily affect populations of this species by altering survival rates of all or particular age classes. The evaluation of this impact and the proposal of mitigation measures (also comprising an educational component) are essential for the conservation of this species in non-breeding grounds.

THE ALPINE LIFE ZONE UNDER GLOBAL CHANGE
Provedor de dados: 73
Autores: Körner,Christian.
Nearly forty percent of mankind depend in one way or another on mountain ecosystems. Local ecosystem services are slope stability, water yield, agricultural products or recreational value. Continental scale influences include drinking water supply, ground water recharging, irrigation water, hydroelectric power, flood control, traffic routes etc. In this paper I review evidence of alpine ecosystem responses to global change. It is emphasized that soil conservation is the centerpiece of any consideration of sustainable land use in alpine terrain. Complete vegetation cover of high biological diversity is essential to protect soils and secure `ecosystem services' in upland systems. It is illustrated that this is not necessarily in conflict with land use and...

We report the genetic structure, relatedness and mating structure of a population of the endangered giant anteater Myrmecophaga tridactyla Linnaeus, 1758 in the Emas National Park, Brazil, based on variability at five microsatellite loci. Additionally, we addressed the hypothesis that the M. tridactyla population studied has low levels of polymorphism and high levels of inbreeding and relatedness and that animals with overlapping home range are highly related. All five microsatellite loci displayed low levels of polymorphism and of expected and observed heterozygosity. The low level of polymorphism and high inbreeding showed by the population studied may be the outcome of high mortality and reduction in population size due to recurrent fire events in the...

Abstract The pampas deer (Ozotoceros bezoarticus) is close to being classified as ‘globally threatened’, with the largest population occurring in the Brazilian Pantanal. Since capture is stressful to these animals, non-invasive sampling methods such as the use of feces can provide reliable sources of DNA. The aim of this study was to use fecal samples to evaluate the genetic variability of the Brazilian Pantanal population of pampas deer. Six heterologous microsatellite markers were used to screen 142 stool specimens. Seventy-four deer were identified, of which 50 adults were used to determine the genetic characteristics of the population. The Pantanal population showed high genetic diversity (mean number of alleles per locus = 11.5, expected...

The complete mitochondrial genome of the brown brocket deer Mazama gouazoubira and a set of polymorphic microsatellite markers were identified by 454-pyrosequencing. De novo genome assembly recovered 98% of the mitochondrial genome with a mean coverage of 9-fold. The mitogenome consisted of 16,356 base pairs that included 13 protein-coding genes, two ribosomal subunit genes, 22 transfer RNAs and the control region, as found in other deer. The genetic divergence between the mitogenome described here and a previously published report was ∼0.5%, with the control region and ND5 gene showing the highest intraspecific variation. Seven polymorphic loci were characterized using 15 unrelated individuals; there was moderate genetic variation across most loci (mean...

Abstract The Morato's Digger Toad, Proceratophrys moratoi, is a critically endangered toad species with a marked population decline in southern Brazilian Cerrado. Despite this, new populations are being discovered, primarily in the northern part of the distribution range, which raises a number of questions with regard to the conservation status of the species. The present study analyzed the genetic diversity of the species based on microsatellite markers. Our findings permitted the identification of two distinct management units. We found profound genetic structuring between the southern populations, on the left margin of the Tietê River, and all other populations. A marked reduction was observed in the contemporary gene flow among the central populations...

Brazilian naturalized goat breeds are adapted to the semiarid conditions prevalent in the Northeast region of the country (which has the largest Brazilian goat heard) and represent an as yet uninvestigated source of genetic diversity. Currently, imported goat breeds are crossed with Brazilian naturalized goat breeds, endangering the genetic potential of the naturalized breeds. We used 11 microsatellite markers to determine the genetic diversity among imported (non-naturalized) dairy Alpine and Saanen goats and naturalized Brazilian Moxotó goats. We genotyped 292 goats from three herds (one private, one from the University of Minas Gerais and the Moxotó conservation herd from Embrapa Caprinos) and found that the general heterozygosity was 0.6952 for Alpine,...

Autores: Arruda,Cinthya Cristina Bulhões; Beasley,Colin Robert; Vallinoto,Marcelo; Marques-Silva,Nelane do Socorro; Tagliaro,Claudia Helena.
Four Brazilian populations of Anomalocardia brasiliana were tested for mutual genetic homogeneity, using data from 123 sequences of the mtDNA cytochrome oxidase c subunit I gene. A total of 36 haplotypes were identified, those shared being H3 (Canela Island, Prainha and Acupe) and both H5 and H9 (Prainha and Acupe). Haplotype diversity values were high, except for the Camurupim population, whereas nucleotide values were low in all the populations, except for that of Acupe. Only the Prainha population showed a deviation from neutrality and the SSD test did not reject the demographic expansion hypothesis. Fst values showed that the Prainha and Acupe populations represent a single stock, whereas in both the Canela Island and Camurupim stocks, population...

Knowledge of the genetic structure and diversity of natural populations is important in developing strategies for in situ and ex situ conservation. We used eight microsatellite loci to estimate genetic structure and investigate within and between population genetic variation in eleven Brazilian wild rice (Oryza glumaepatula) populations. The study showed the following genetic diversity parameters: average number of 3.1 alleles per locus; 77.3% polymorphic loci; 0.091 observed heterozygosity and 0.393 gene diversity. F-statistics detected by microsatellite loci were: F ST = 0.491 (and R ST = 0.608), F IS = 0.780 and F IT = 0.888. No population was in Hardy-Weinberg equilibrium. The estimated apparent outcrossing rate (0.143) indicated a predominance of...

Twelve microsatellite loci previously developed in the tropical tree Cariniana estrellensis were genetically characterized in Cariniana legalis. Polymorphisms were assessed in 28 C. legalis individuals found between the Pardo and Mogi-Guaçu River basins in the state of São Paulo, Brazil. Of the 12 loci, 10 were polymorphic and exhibited Mendelian inheritance. The allelic richness at each locus ranged from 2-11, with an average of 7 alleles per locus, and the expected heterozygosity ranged from 0.07-0.88. These loci showed a high probability of paternity exclusion. The characteristics of these heterologous microsatellite markers indicate that they are suitable tools for investigating questions concerning population genetics in C. legalis.

Genetic diversity and population structure of Vriesea reitzii (Bromeliaceae), a species from the Southern Brazilian Highlands
Provedor de dados: 74
Autores: Soares,Luis Eduardo; Goetze,Márcia; Zanella,Camila M.; Bered,Fernanda.
Abstract The Southern Brazilian Highlands are composed by a mosaic of Mixed Ombrophilous Forest (MOF) and grassland formations, an interesting landscape for the study of population structure. We analyzed the genetic diversity within and among populations of the MOF-endemic bromeliad Vriesea reitzii by genotyping seven nuclear microsatellite loci in 187 individuals from six populations. We characterized levels of genetic diversity and assessed the genetic structure among populations. Vriesea reitzii populations showed high levels of genetic variation (number of alleles 28 - 43, allelic richness 3.589 - 5.531) and moderate levels of genetic differentiation (FST = 0.123, RST = 0.096). The high levels of genetic diversity may be explained by species...

Abstract Marine turtle hybridization is usually sporadic and involves reports of only a few individuals; however, Brazilian populations have high hybridization rates. Here we investigated the presence of hybrids in morphologically identified immature hawksbills (Eretmochelys imbricata) along the South Western Atlantic (SWA). We sequenced one mitochondrial (D-Loop) and three nuclear DNA (RAG1, RAG2, and CMOS) markers to better understand the patterns and characteristics of hybrids. We identified 22 hybrids (n = 270), 11 of them at the extreme South of the SWA. Uruguay had the highest hybrid frequency in the SWA (~37.5%) followed by southern Brazil with 30%. These are common areas for loggerheads (Caretta caretta) but uncommon for hawksbills, and these...

Autores: Rodrigues-Filho,Luis Fernando da Silva; Rocha,Tainá Carreira da; Rêgo,Péricles Sena do; Schneider,Horacio; Sampaio,Iracilda; Vallinoto,Marcelo.
The ongoing decline in abundance and diversity of shark stocks, primarily due to uncontrolled fishery exploitation, is a worldwide problem. An additional problem for the development of conservation and management programmes is the identification of species diversity within a given area, given the morphological similarities among shark species, and the typical disembarkation of processed carcasses which are almost impossible to differentiate. The main aim of the present study was to identify those shark species being exploited off northern Brazil, by using the 12S-16S molecular marker. For this, DNA sequences were obtained from 122 specimens collected on the docks and the fish market in Bragança, in the Brazilian state of Pará. We identified at least 11...

Autores: Presti,Flavia T.; Oliveira-Marques,Adriana R.; Caparroz,Renato; Biondo,Cibele; Miyaki,Cristina Y.
Cross-amplification was tested and variability in microsatellite primers (designed for Neotropical parrots) compared, in five macaw species, viz., three endangered blue macaws (Cyanopsitta spixii [extinct in the wild], Anodorhynchus leari [endangered] and Anodorhynchus hyacinthinus [vulnerable]), and two unthreatened red macaws (Ara chloropterus and Ara macao). Among the primers tested, 84.6% successfully amplified products in C. spixii, 83.3% in A. leari, 76.4% in A. hyacinthinus, 78.6% in A. chloropterus and 71.4% in A. macao. The mean expected heterozygosity estimated for each species, and based on loci analyzed in all the five, ranged from 0.33 (A. hyacinthinus) to 0.85 (A. macao). As expected, the results revealed lower levels of genetic variability...

Parapiptadenia rigida is a tropical early secondary succession tree characteristic of the Tropical Atlantic Rainforest. This species is of great ecological importance in the recovery of degraded areas. In this study we investigated the variability and population genetic structure of eight populations of P. rigida. Five AFLP primer combinations were used in a sample of 159 individuals representing these eight populations, rendering a total of 126 polymorphic fragments. The averages of percentage of polymorphic loci, gene diversity, and Shannon index were 60.45%, 0.217, and 0.322, respectively. A significant correlation between the population genetic variability and the population sizes was observed. The genetic variability within populations (72.20%) was...

Genetic structure of red-handed howler monkey populations in the fragmented landscape of Eastern Brazilian Amazonia
Provedor de dados: 74
Autores: Bastos,Heitor B.; Gonçalves,Evonnildo C.; Ferrari,Stephen F.; Silva,Artur; Schneider,Maria Paula C.
We genotyped 15 microsatellite loci in order to evaluate the effects of habitat fragmentation, caused by flooding of the Tucuruí reservoir, on the genetic structure of Alouatta belzebul in eastern Amazonia. The analysis included two populations sampled in 1984, representing both margins of the Tocantins river, and three populations sampled 18 years later. Minimal differences in the diversity levels between present-day (Ho = 0.62-0.69 and A R = 6.07-7.21) and pre-flooding (Ho = 0.60-0.62 and A R = 6.27-6.77) populations indicated there was no significant loss of genetic variability, possibly because of successful management strategies applied during the flooding. The changes observed were limited to shifts in the composition of alleles, which presumably...

Comparative analysis of the complete chloroplast genomes from six Neotropical species of Myrteae (Myrtaceae)
Provedor de dados: 74
Autores: Rodrigues,Nureyev F.; Balbinott,Natalia; Paim,Igor; Guzman,Frank; Margis,Rogerio.
Abstract Myrteae is the largest and most diverse tribe within Myrtaceae and represents the majority of its diversity in the Neotropics. Members of Myrteae hold ecological importance in tropical biomes for the provision of food sources for many animal species. Thus, due to its several roles, a growing interest has been addressed to this group. In this study, we report the sequencing and de novo assembly of the complete chloroplast (cp) genomes of six Myrteae species: Eugenia brasiliensis, E. pyriformis, E. nitida, Myrcianthes pungens, Plinia edulis and Psidium cattleianum. We characterized genome structure, gene content, and identified SSRs to detect variation within Neotropical Myrteae. The six newly sequenced plastomes exhibit a typical quadripartite...

Population structure analysis of Pimelodus maculatus (Pisces, Siluriformes) from the Tietê and Paranapanema Rivers (Brazil)
Provedor de dados: 74
Autores: Almeida,Fernanda Simões de; Sodré,Leda Maria Koelblinger; Contel,Eucleia Primo Betioli.
Pimelodus maculatus populations from the Tietê and Paranapanema rivers were sampled and had their genetic structure analyzed by using RAPD markers, with the aim of contributing to future conservation studies. The proportion of polymorphic loci was greater than 50% in the populations of both rivers. Genetic diversity data showed that, in spite of its nine hydroelectric plants, the Tietê river population was genetically homogeneous, whereas the Paranapanema river population was structured. This might be due to the presence of high waterfalls distributed all along its course. These data may serve as indicators for future conservation studies on the Tietê and Paranapanema rivers.

Abstract The dusky grouper, Epinephelus marginatus, is a well-known and widespread marine fish assessed as endangered by the International Union for the Conservation of Nature. Analyzing the genetic diversity of this species is, therefore, of utmost importance and necessary for conservation purposes. Microsatellites are molecular tools with advantages that are ideal for population analyses. This study provides the first set of species-specific microsatellite loci for E. marginatus that can be applied when assessing both intra- and interpopulation genetic variation. Twenty microsatellite loci were isolated and characterized for the dusky grouper by genotyping 20 individuals obtained from the North Eastern Atlantic Ocean (n = 4) and from the South Western...

Provedor de dados: 74
Autores: Brandão,José Henrique S. G.; Rodrigues,Nureyev F.; Eguiluz,Maria; Guzman,Frank; Margis,Rogerio.
Abstract Araucaria angustifolia is endemic to southern Brazil. Known as Brazilian pine, A. angustifolia is the only native conifer species with economic and social relevance in this country. Due to massive exploitation, it has suffered a significant population decline and currently is classified as critically endangered. This encouraged the scientific community to investigate genetic features in Brazilian pine to increase resources for management and preservation. In this work, RNA-Seq data was used to determine the complete nucleotide sequence of the A. angustifolia chloroplast genome (cpDNA). The cpDNA is 146,203 bp in length and contains 122 genes, including 80 protein-coding genes, 5 ribosomal RNA genes, and 37 tRNA genes. Coding regions comprise...

Estimating dispersal and gene flow in the neotropical freshwater turtle Hydromedusa maximiliani (Chelidae) by combining ecological and genetic methods
Provedor de dados: 74
Autores: Souza,Franco L.; Cunha,Anderson F.; Oliveira,Marcos A.; Pereira,Gonçalo A.G.; Reis,Sérgio F. dos.
Hydromedusa maximiliani is a vulnerable neotropical freshwater turtle endemic to mountainous regions of the Atlantic rainforest in southeastern Brazil. Random amplified polymorphic DNA (RAPD) was used to estimate the gene flow and dispersal for individuals inhabiting rivers and streams within a drainage. Nine primers generated 27 scoreable bands, of which 9 (33%) were polymorphic and produced 12 RAPD phenotypes. The gene flow estimates (Nm) among turtles inhabiting different rivers and streams were variable, ranging from 0.09 to 3.00 (mean: 0.60). For some loci, the rates of gene flow could offset population differentiation (Nm &gt; 1), whereas for others random genetic drift could result in population divergence (Nm &lt; 1). Since the genetic variation of...

Linkage disequilibrium and past effective population size in native Tunisian cattle
Provedor de dados: 74
Autores: Jemaa,Slim Ben; Thamri,Nejia; Mnara,Sofiane; Rebours,Emmanuelle; Rocha,Dominique; Boussaha,Mekki.
Abstract To carry out effective genome-wide association studies, information about linkage disequilibrium (LD) is essential. Here, we used medium-density SNP chips to provide estimates of LD in native Tunisian cattle. The two measures of LD that were used, mean r2 and D’, decreased from 0.26 to 0.05 and from 0.73 to 0.40, respectively, when the distance between markers increased from less than 20 Kb to 200 Kb. The decay in LD over physical distance occurred at a faster rate than that reported for European and other indigenous breeds, and reached background levels at less than 500 Kb distance. This is consistent with the absence of strong selective pressure within the Tunisian population and suggests that, in order to be effective, any potential genome-wide...

Temporary storage of jussara palm seeds: effects of time, temperature and pulp on germination and vigor
Provedor de dados: 75
Autores: Martins,Cibele C.; Bovi,Marilene L. A.; Nakagawa,João; Godoy Júnior,Gentil.
Seeds of jussara palm (Euterpe edulis Mart.) are recalcitrant, presenting low longevity, high sensitivity to dehydration and to low temperatures of storage. Temperature conditions for temporary preservation of those seeds, with and without pulp, were studied. Mature fruits were harvested from 24 plants belonging to the palm collection of the Instituto Agronômico (IAC) located at Ubatuba, São Paulo State, Brazil, and taken in moisture-proof containers to the Universidade Estadual de São Paulo, in Botucatu, São Paulo State. Half of the fruits were shelled and the seeds stored, with and without pulp, in sealed plastic bags (20 µm thick) maintained in chambers with temperatures of 5; 10; 15 and 20-30ºC. Samples for the quality tests were taken at 0; 3; 6; 9...

Autores: Silva,Luana Cristina R da; Azevedo,Alcinei M; Pedrosa,Carlos E; Andrade Júnior,Valter C; Valadares,Nermy R; Araújo,Vanessa V de; Ferreira,Evander A.
ABSTRACT The selection of kale genotypes more resistant to dehydration is important, since this product is marketed fresh and characterized as perishable. For the post-harvest study, the adjustment of regression models is useful. However, when there are many treatments, it is difficult to identify the superior one through the graphical representation of the curves. In this sense, the model identity test groups the curves establishing genotypes that have statistically similar behavior. Thus, we aimed to select kale accesses for post-harvest dehydration using the model identity test. The accumulated loss of fresh matter of 22 kale genotypaes was evaluated, being 19 of the germplasm bank of the UFVJM and three commercial cultivars (COM). The model identity...

Quality of mini tomatoes harvested at two maturity stages and kept chilled in three packages
Provedor de dados: 75
Autores: Caron,Vanessa C; Tessmer,Magda A; Mello,Simone C; Jacomino,Angelo P.
The economic importance of small tomato fruits has been increased considerably due to the significant levels of lycopene and sugars. However, to achieve these compounds, the harvest is limited to a ripening stage demanded by consumers, which could reduce this marked period. Harvesting at an early stage and use of conservation techniques are desirable to amplify the marketing period. The aim of this study was to evaluate the quality of small tomato fruits, Sweet Grape cultivar, harvested at two stages of ripening (light red and red), kept in three types of package (perforated PET, PEBD 30 μ and Vegetal Pack 18 μ) at a temperature of 20±1ºC and a relative humidity (RH) of 85±5% during 20 days. During this period, gas composition inside the packaging (O2, CO2...

Climate and land-use changes effects on the distribution of a regional endemism: Melanophryniscus sanmartini (Amphibia, Bufonidae)
Provedor de dados: 76
Autores: Rosenstock,Nicole; Toranza,Carolina; Brazeiro,Alejandro.
ABSTRACT Amphibians are the most threatened vertebrate group according to the IUCN. Land-use and land cover change (LULCC) and climate change (CC) are two of the main factors related to declining amphibian populations. Given the vulnerability of threatened and rare species, the study of their response to these impacts is a conservation priority. The aim of this work was to analyze the combined impact of LULCC and CC on the regionally endemic species Melanophryniscus sanmartini Klappenbach, 1968. This species is currently categorized as near threatened by the IUCN, and previous studies suggest negative effects of projected changes in climate. Using maximum entropy methods we modeled the effects of CC on the current and mid-century distribution of M....

Autores: Dias,Rafael A; Gonçalves,Maycon S. S; Bastazini,Vinicius A. G.
The only breeding record of Spartonoica maluroides (d'Orbigny &amp;amp; Lafresnaye, 1837) for Brazil is based on the observation of a fledgling in southern Rio Grande do Sul in January 1976. On 7 December 2005 we discovered a nest containing three nestlings at the southeastern end of Lagoa Pequena, municipality of Pelotas, Rio Grande do Sul. The nest was concealed at the base of a cavity in a Spartina densiflora (Poaceae) tussock located at the edge of a saltmarsh. The nest was built of fine pieces of dead Scirpus olneyi (Cyperaceae) and S. densiflora leaves firmly interlaced to the internal leaves of the tussock. Live leaves of S. densiflora lining the cavity comprised a substantial part of the nest's architecture, forming most of its upper lateral walls...

Nestedness of stream insects in Subtropical region: importance of inter-annual temporal scale
Provedor de dados: 76
Autores: Hepp,Luiz U.; Milesi,Silvia V.; Nava,Diane; Restello,Rozane M.
ABSTRACT Stream insects use in different ways the stream habitats which affect patterns of species occurrence on stream. The nestedness is one of these patterns being an ecological mechanism that generates beta diversity. In this study, we verify the effects of temporal environmental variations on nestedness patterns of Chironomidae assemblages on subtropical streams. We collected chironomid larvae during winter and summer during three years (2010, 2011 and 2012) in Brazilian Subtropical low-order streams (Erechim, state of Rio Grande do Sul, Brazil). We measured environmental variables in each stream. To assess if assemblages will show nested patterns intra- and interannual we used a NODF metric. We observed nestedness only in one year, this pattern was...

Several factors, such as hunting and the pet trade, are responsible for the worldwide decline of wildlife populations. In addition, fatal collisions with vehicles on highways have also taken one of the largest tolls. This study aimed to quantify the richness and abundance of vertebrate roadkill along highway MS-080 in Mato Grosso do Sul, Central-West Brazil. We compare the amount of roadkill to the distance between cities, moon phases and the flow of vehicles on the highway. Samples were collected weekly between March and September 2011, totaling 257 individuals, belonging to 32 families and 52 species, resulting in an index of 0.13 individuals hit/km. Birds were the most frequently hit taxa, followed by mammals. The most affected species was Cariama...

ABSTRACT Knickzones are originated from basaltic outcroppings, present runs, riffles and pools and are highly influenced by flood pulses, which maintain their natural dynamic. However, the construction of hydroelectric power plants alters or eliminate the dynamism of this area and can affect the resident fauna that may be dependent on it. The aim of this study was to evaluate the organization of a knickzone’s ichthyofauna considering the influence of seasonality and connectivity of habitats. The study was performed in a knickzone located in the Sapucaí-Mirim River, Southeast Brazil. We sampled four rocky pools connected to the river and three isolated pools, during rainy and dry conditions. The analysis of the two factors (connectivity and seasonality) and...

ABSTRACT Tropical streams feature high variety of habitats and environmental gradients, which reflect on the greater richness of aquatic insects. In this way, we evaluate if the diversity of aquatic insects of prey and predator categories is influenced by the type of substrates or by longitudinal portions in Cerrado streams. Our hypothesis is that prey and predator diversity will be determined by the type of substrate, assuming that the substrate serves as a source for foraging and / or refuge. In addition, the folhiço substrate will present greater abundance and richness due to the availability of shelter and food provided by this type of substrate. There will be differences in prey and predator composition among substrates, since some species have...

Provedor de dados: 14
Autores: EMBRAPA. Centro de Pesquisa Agropecuária do Trópico Semi-Árido.
Um experimento conduzido nos anos agricolas de 1982 a 1985, no campo experimental de manejo da Caatinga, EMBRAPA-CPATSA, avaliou-se tres sistemas de captacao de agua de chuva "in situ", metodos: Guimaraes Duque, CP-Mexico e Sulcos e Camalhoes, em curva de nivel, comparando-os com o sistema tradicional de preparo do solo e plantio, em covas e no plano. O delineamento foi em blocos ao acaso com oito repeticoes, instalado em escala operacional. As condicoes climaticas influenciaram ao nivel de 1,0% de probabilidade sobre a produtividade do caupi, e a interacao clima x tratamento foi significativa ao nivel de 5,0% de probabilidade. Nos anos de precipitacoes pluviometricas espaco-temporais irregulares, fato comum na regiao semi-arida brasileira, os metodos...

A Caatinga é o único bioma de distribuição exclusivamente brasileira, o que significa que grande parte do patrimônio biológico desse ecossistema não é encontrada em nenhum outro lugar do mundo. Porém, essa posição única entre os biomas brasileiros não foi suficiente para garantir a Caatinga o status que merece. A Caatinga é um dos biomas brasileiros mais alterados pelas atividades humanas, com mais de 45% de sua área alterada, sendo ultrapassado apenas pela Mata Atlântica e o Cerrado (Capobianco, 2002; Casteletti e cols., 2004). Em um estudo realizado recentemente, sobre a vegetação e uso do solo, verificou-se que a área de cobertura vegetal da Caatinga é de 518.635 Km2, equivalendo a 62,69% de remanescentes (MMA, 2008). Como conseqüência da degradação...

Princípios de agroecologia no manejo das pastagens nativas do Pantanal.
Provedor de dados: 14
Autores: SANTOS, S. A.; CRISPIM, S. M. A.; COMASTRI FILHO, J. A.; CARDOSO, E. L.
O manejo sustentável das pastagens nativas do Pantanal deve seguir os princípios da agroecologia, onde são considerados as inter-relações entre os diversos elementos do agroecossistema. De maneira geral, um agroecossistema é sustentável quando maximiza o potencial produtivo dos ecossistemas, mantendo a produtividade ao longo do tempo, com a utilização mínima de insumos externos (suplementos alimentares, fertilizantes, antibióticos, etc.), sem degradar os recursos naturais renováveis. No entanto, para se ter uma visão holística do sistema, há a necessidade de muitas observações e conhecimentos (pesquisas interativas) sobre as reais necessidades das plantas e animais. Segundo Primavezi (1999), o manejo das pastagens é uma arte e exige muito bom senso e...

Erosao e praticas conservacionistas nos cerrados.
Provedor de dados: 14
Autores: DEDECEK, R. A.
Uma agricultura intensiva e permanente depende muito do equilibrio entre perdas e ganhos de nutrientes. Os ganhos sao representados pela adubacoes quimicas e organicas e incorporacao da resteva, e as perdas, pelo cultivos, lixiviacao, volatilizacao e erosao. A erosao nao e seletiva quimicamente, nao produzindo concentracoes diversificadas de nutrientes entre o sedimento e o solo que o formou (tabela 1). A selecao ocorre no maior arraste da materia organica e das particulas mais finas do solo, que sao as armazenadoras dos nutrientes. Os menores teores de nutrientes no tratamento solo descoberto devem-se ao fato de que este recebeu apenas adubacao corretiva de P e K, alem da calagem, em 1977, tendo sido mantido sem vegetacao desde entao e preparado todos...

Sugestões de uso e manejo dos solos do Assentamento Taquaral, Corumbá - MS.
Provedor de dados: 14
Autores: CARDOSO, E. L.; OLIVEIRA, H. de.
A implantação de Projetos de Assentamentos Rurais nas terras não inundáveis ao redor de Corumbá e Ladário fez com que a agricultura passasse a fazer parte das atividades econômicas desses municípios. No entanto, a atividade agrícola nestas terras encontra severas limitações à obtenção de elevadas produtividades, decorrentes principalmente da deficiência de água para as plantas, determinada pelo expressivo período seco que ocorre na região. No Assentamento Taquaral, esta limitação é acentuada pela predominância de solos com textura argilosa a muito argilosa, determinando: drenagem imperfeita e pouca permeabilidade, fazendo com que o solo permaneça encharcado por muito tempo durante o período chuvoso; dificuldade de mecanização, devido a elevada plasticidade...

Os cavalos introduzidos no Pantanal pelos conquistadores durante a epoca da colonizacao, encontraram na regiao condicoes ambientais propicias para sua multiplicacao. Como consequencia dos processos adaptativos e da selecao natural por mais de dois seculos e com pouca ou nenhuma interferencia antropica, surgiu um tipo adaptado ao meio. Com o desenvolvimento da pecuaria na regiao, o cavalo Pantaneiro constituiu-se num fator de importancia economica e social, tornando-se imprescindivel em trabalhos de gado e no transporte regional. No final do seculo XIX, a raca entrou em declinio principalmente devido a doenca conhecida como Peste das cadeiras e, posteriormente, outras ameacas como cruzamentos indiscriminados com outras racas e, mais recentemente a Anemia...

Aves migratórias ocorrentes no Pantanal: caracterização e conservação.

Periodicamente o Brasil é visitado por milhares de aves que realizam movimentos sazonais da América do Norte para a América do Sul e vice-versa (Sick 1983, Morrison et al. 1989, Chesser 1994). Dentre as aves que visitam o território nacional, destacam-se aquelas que migram com a proximidade do inverno boreal (Antas 1994). Os migrantes vêm ao Brasil à procura de locais de invernada, onde encontram alimentação farta, propiciando-lhes a continuidade do seu ciclo de vida (Telino Jr. et al. 2003). Estas aves apresentam extraordinária capacidade de percorrer longas distâncias (Hayman et al. 1986; Antas 1989; Morrison et al. 1989; Sick 1983, 1997; Azevedo Jr. et al. 2002, Alerstan et al. 2003).

Autores: FREITAS, M. B. de; CHOUDHURY, E. N.; FARIA, C. M. B. de.
Este trabalho constituiu-se de três experimentos conduzidos por vários anos na zona fisiográfica do Agreste de pernambuco, com o objetivo de encontrar práticas de manejo e conservação de solo que proporcionassem melhores resultados ao cultivo do tomate em condições de sequeiro. O primeiro experimento continha os seguintes tratamentos: 1. Solo lavrado e com cultivo contínuo; 2. Solo lavrado e com rotação bienal; 3. Solo não lavrado e com rotação bienal. A rotação era formada do cultivo de tomate em um ano e da leguminosa feijão-de-porco em outro ano. No solo lavrada e em cultivo contínuo de tomate, ocorreram as maiores perdas de solo e a menor produtividade do tomateiro. Maior controle da erosão e maior produtividade foram obtidos no solo não lavrado e em...

Assessing the relationships between phylogenetic and functional singularities in sharks (Chondrichthyes)
Provedor de dados: 5
Autores: Cachera, Marie; Le Loc'H, Francois.
The relationships between diversity and ecosystem functioning have become a major focus of science. A crucial issue is to estimate functional diversity, as it is intended to impact ecosystem dynamics and stability. However, depending on the ecosystem, it may be challenging or even impossible to directly measure ecological functions and thus functional diversity. Phylogenetic diversity was recently under consideration as a proxy for functional diversity. Phylogenetic diversity is indeed supposed to match functional diversity if functions are conservative traits along evolution. However, in case of adaptive radiation and/or evolutive convergence, a mismatch may appear between species phylogenetic and functional singularities. Using highly threatened taxa,...

An adaptable toolkit to assess commercial fishery costs and benefits related to marine protected area network design
Provedor de dados: 5
Autores: Daigle, Rémi M.; Monaco, Cristian; Elgin, Ashley K.
Around the world, governments are establishing Marine Protected Area (MPA) networks to meet their commitments to the United Nations Convention on Biological Diversity. MPAs are often used in an effort to conserve biodiversity and manage fisheries stocks. However, their efficacy and effect on fisheries yields remain unclear. We conducted a case-study on the economic impact of different MPA network design strategies on the Atlantic cod (Gadus morhua) fisheries in Canada. The open-source R package that we developed to analyze this case study can be customized to conduct similar analyses for other systems. We used a spatially-explicit individual-based model of population growth and dispersal coupled with a fisheries management and harvesting component. We...

Autores: Stier, Anna; De Carvalho, William D.; Rostain, Stephen; Catzeflis, Francois; Claessens, Olivier; Dewynter, Mael; Mckey, Doyle; Mustin, Karen; Palisse, Marianne; De Thoisy, Benoit.
The Amazonian savannas of French Guiana are rare and of high ecological and cultural value but are also highly threatened. They are socioecological systems that have been coconstructed by humans and nature and today form mosaic landscapes along the country's coast. From pre-Columbian raised fields through colonial and Creole uses to contemporary uses, they have been largely shaped and modified by human activities. They are currently threatened by changes in fire regimes, agricultural practices, invasive species, and infrastructure development. Less than 3% are protected, despite their importance for several endangered animal and plant species. A shift is required in the way we think about their conservation to create a new strategy that would be completely...

Aim Identifying the multifaceted biodiversity hotspots for marine mammals and their spatial overlap with human threats at the global scale. Location World-wide. Methods We compiled a functional trait database for 121 species of marine mammals characterized by 14 functional traits grouped into five categories. We estimated marine mammal species richness (SR) as well as functional (FD) and phylogenetic diversity (PD) per grid cell (1° × 1°) using the FRic index (a measure of trait diversity as the volume of functional space occupied by the species present in an assemblage) and the PD index (the amount of evolutionary history represented by a set of species), respectively. Finally, we assessed the spatial congruence of these three facets of biodiversity...

The Paris Conference of Parties (COP21) agreement renewed momentum for action against climate change, creating the space for solutions for conservation of the ocean addressing two of its largest threats: climate change and ocean acidification (CCOA). Recent arguments that ocean policies disregard a mature conservation research field and that protected areas cannot address climate change may be oversimplistic at this time when dynamic solutions for the management of changing oceans are needed. We propose a novel approach, based on spatial meta-analysis of climate impact models, to improve the positioning of marine protected areas to limit CCOA impacts. We do this by estimating the vulnerability of ocean ecosystems to CCOA in a spatially explicit manner and...

Banning is not enough: The complexities of oceanic shark management by tuna regional fisheries management organizations
Provedor de dados: 5
Autores: Travassos Tolotti, Mariana; Filmalter, John David; Bach, Pascal; Travassos, Paulo; Seret, Bernard; Dagorn, Laurent.
Recently, declining populations of several pelagic shark species have led to global conservation concerns surrounding this group. As a result, a series of species-specific banning measures have been implemented by Regional Fishery Management Organizations (RFMOs) in charge of tuna fisheries, which include retention bans, finning bans and trading bans. There are both positive and negative aspects to most management measures, but generally, the positive aspects outweigh the negatives, ensuring the measure is beneficial to the resource and its users in the long term. Banning measures are a good first step towards the conservation of pelagic shark species, especially since they improve conservation awareness among fishers, managers and the public. Measures...

Autores: De Wit, Rutger; Leruste, Amandine; Le Fur, Ines; Maki Sy, Mariam; Bec, Beatrice; Ouisse, Vincent; Derolez, Valerie; Rey-valette, Hélène.
By the end of the 20th century, many of the coastal lagoons along the French Mediterranean coast showed insufficient water quality and degraded ecosystem states due to anthropogenic impacts. Among these, nutrient over-enrichment, resulting in eutrophication, has been a major concern. The EU Water Framework Directive (WFD) has initiated public action to improve their water quality and ecosystem state using an approach rooted in restoration ecology. Here we analyze how this has been applied for the coastal lagoons in South France, considering eutrophication as an example of ecosystem degradation and oligotrophication as the corresponding trajectory for ecological restoration of the eutrophied coastal lagoons. Oligotrophication trajectories, initiated by the...

Historique de la raréfaction des poissons marins (incidence des activités de pêche sur les poissons dans les eaux marines d'Arcachon du 18eme siècle a nos jours)
Provedor de dados: 5
Autores: Quero, Jean-claude; Cendrero, Orestes.
Au 18ème siècle, dans la moitié sud du golfe de Gascogne, caractérisée par un plateau continental plus étroit, le bassin d'Arcachon, vaste lagune ouverte sur la mer, était considéré par Le Masson du Parc (1727) comme "un des plus poissonneux que l'on puisse voir". L'auteur écrivait que de "mémoire d'homme" le niveau des captures n'avait pas sensiblement diminué. Environ 500 marins péchaient presque exclusivement dans le Bassin à la saison chaude. La moitié d'entre eux sortaient en mer capturer du poisson à la saison froide, les autres récoltant les coquillages dans la lagune. Des données postnapoléoniennes montrent d'après l'importance de sa population maritime, que le Bassin était la pêcherie la plus importante de la côte Atlantique française tout au...

Ce rapport fait état d'une étude réalisée au laboratoire de Génétique et Pathologie de l'IFREMER dans le cadre de l'analyse d'épisodes de mortalité anormale survenue en écloserie privée de crevettes pénéides. Plusieurs hypothèses ont été avancées. La présence de Vibrio harveyi a amené à constituer une collection de 40 souches à partir desquelles une identification bactériologique a été effectuée. Elle montre en effet une dominance de souches appartenant à un groupe homogène de Vibrio harveyi. La technique de ribotypage (digestion d'ADN génomique, transfert de Southem-blot et hybridation avec une sonde spécifique) est alors mise en place. Plusieurs difficultés techniques ont ralenti l'analyse et n'ont donc pas permis d'avoir des résultats assez avancés pour...

Towards an Autonomous Pelagic Observatory: Experiences from Monitoring Fish Communities around Drifting FADs
Provedor de dados: 5
Autores: Brehmer, Patrice; Sancho, Gorka; Trygonis, Vasilis; Itano, David; Dalen, John; Fuchs, Ariel; Faraj, Abdelmalek; Taquet, Marc.
This work presents a methodological synthesis for the in situ monitoring of fish aggregating devices (FADs) using a combination of optical, echosounder and SCUBA observations conducted in the vicinity of drifting FADs. The acoustic methods allowed, according to the devices used, the description of the spatial organisation and dynamics of biotic scattering layers, individual fishes, schools, shoals and mammals, while visual, photographic and video observations permitted species identification within a range of 0 to ~ 25 m. Based on these results, we elaborate on the interest to combine acoustic and visual methods, and present an autonomous instrumented drifting buoy for remotely monitoring fish diversity and abundance in the pelagic ecosystems.

The PCNA from Thermococcus fumicolans functionally interacts with DNA polymerase delta
Provedor de dados: 5
Autores: Henneke, Ghislaine; Raffin, Jean-paul; Ferrari, Elena; Jonsson, Zophonías; Dietrich, Jacques; Hubscher, Ulrich.
We have cloned the gene encoding proliferating cell nuclear antigen (PCNA) from the hyperthermophilic euryarchaeote Thermococcus fumicolans (Tfu). Tfu PCNA contains 250 amino acids with a calculated M-r of 28,000 and is 26% identical to human PCNA. Next, Tfu PCNA was overexpressed in Escherichia coli and it showed an apparent molecular mass of 33.5 kDa. The purified Tfu PCNA was tested first with recombinant Tfu DNA polymerase I (Tfu pol) and second with calf thymus DNA polymerase delta (pol delta). When tested with the homologous Tfu pol on bacteriophage lambda DNA, large amounts of Tfu PCNA were required to obtain two- to threefold stimulation. Surprisingly, however, Tfu PCNA was much more efficient than human PCNA in stimulating calf thymus pol delta....

Spatio-temporal patterns in demersal elasmobranchs from trawl surveys in the eastern English Channel (1988-2008)
Provedor de dados: 5
Autores: Martin, Corinne; Vaz, Sandrine; Ellis, J. R.; Coppin, Franck; Le Roy, Didier; Carpentier, Andre.
Elasmobranchs have life-history characteristics that make them more vulnerable to fishing than many teleost fish. As commercial landings data are usually not sufficient for the monitoring and assessment of elasmobranchs, fisheries-independent data, geostatistics and Geographic Information Systems were used to investigate the spatio-temporal patterns of sharks (6 species), skates (9 species) and stingray in the eastern English Channel. Temporal trends in relative abundance and distributions of total-length frequencies were investigated using data collected over 21 yr from an annual survey using a Grande Ouverture Verticale (GOV) trawl. Temporal trends in relative abundance were examined qualitatively in relation to the reported conservation status for the...

Autores: Bruno, John F.; Saumweber, Whitley; Crowder, Larry B.; Pendleton, Linwood; Roady, Stephen E.; Rouleau, Tracy; Sakashita, Miyoko.
The United States has been at the forefront of marine resource stewardship since the 1970s when Federal officials began to implement a series of national policies aimed at the conservation and management of public trust resources in the ocean. Beginning with the establishment of the National Oceanic and Atmospheric Administration in 1970, soon followed by several pieces of landmark legislation, this era marked the start of a continuing effort to integrate ecosystem science with marine resource management. Among the most important bipartisan legacies of this effort has been the steady expansion of marine managed areas in U.S. coastal and ocean waters. This legacy is being challenged as the Trump Administration considers whether to alter or eliminate the...

Using genetics to inform restoration and predict resilience in declining populations of a keystone marine sponge
Provedor de dados: 5
Autores: Griffiths, Sarah M.; Taylor-cox, Evelyn D.; Behringer, Donald C.; Butler, Mark J.; Preziosi, Richard F.
Genetic tools can have a key role in informing conservation management of declining populations. Genetic diversity is an important determinant of population fitness and resilience, and can require careful management to ensure sufficient variation is present. In addition, population genetics data reveal patterns of connectivity and gene flow between locations, enabling mangers to predict recovery and resilience, identify areas of local adaptation, and generate restoration plans. Here, we demonstrate a conservation genetics approach to inform restoration and management of the loggerhead sponge (Spheciospongia vesparium) in the Florida Keys, USA. This species is a dominant, habitat-forming component of marine ecosystems in the Caribbean region, but in Florida...

Changes in the genetic structure of Atlantic salmon populations over four decades reveal substantial impacts of stocking and potential resiliency
Provedor de dados: 5
Autores: Perrier, Charles; Guyomard, Rene; Bagliniere, Jean-luc; Nikolic, Natacha; Evanno, Guillaume.
While the stocking of captive-bred fish has been occurring for decades and has had substantial immediate genetic and evolutionary impacts on wild populations, its long-term consequences have only been weakly investigated. Here, we conducted a spatiotemporal analysis of 1428 Atlantic salmon sampled from 1965 to 2006 in 25 populations throughout France to investigate the influence of stocking on the neutral genetic structure in wild Atlantic salmon (Salmo salar) populations. On the basis of the analysis of 11 microsatellite loci, we found that the overall genetic structure among populations dramatically decreased over the period studied. Admixture rates among populations were highly variable, ranging from a nearly undetectable contribution from donor stocks...

Modeling of degraded reefs in Leyte Gulf, Philippines in the face of climate change and human-induced disturbances
Provedor de dados: 5
Autores: Tan, Barron Cedric; Anticamara, Jonathan; Villanueva, Ching-maria.
Philippine reefs are mega-diverse but, to date, few ecosystem models have been developed to understand their dynamics and functioning. This study assessed the status of reefs in 12 municipalities of Leyte Gulf, Philippines. It is an important fishing ground experiencing degradation and impacts of super-typhoons—the strongest one was Haiyan (local name: Yolanda). Empirical and literature data were used to develop Ecopath (trophic) models and Ecosim simulations to evaluate the impacts of reduction and increase in productivity on the Leyte Gulf Reef (LGR) ecosystem. Results showed that the LGR’s ecosystem is in a degraded state—dominated by small-medium herbivores and carnivores, with most productivity immediately returned to detritus. In addition, a...

Submarine canyons are major geomorphic features of continental margins around the world. Several recent multidisciplinary projects focused on the study of canyons have considerably increased our understanding of their ecological role, the goods, and services they provide to human populations, and the impacts that human activities have on their overall ecological condition. Pressures from human activities include fishing, dumping of land-based mine tailings, and oil and gas extraction. Moreover, hydrodynamic processes of canyons enhance the down-canyon transport of litter. The effects of climate change may modify the intensity of currents. This potential hydrographic change is predicted to impact the structure and functioning of canyon communities as well...

Coral reefs host hundreds of thousands of animal species that are increasingly threatened by anthropogenic disturbances. These animals host microbial communities at their surface, playing crucial roles for their fitness. However, the diversity of such microbiomes is mostly described in a few coral species and still poorly defined in other invertebrates and vertebrates. Given the diversity of animal microbiomes, and the diversity of host species inhabiting coral reefs, the contribution of such microbiomes to the total microbial diversity of coral reefs could be important, yet potentially vulnerable to the loss of animal species. Analysis of the surface microbiome from 74 taxa, including teleost fishes, hard and soft corals, crustaceans, echinoderms,...

High species richness and unique composition of the tanaidacean communities associated with five areas in the Pacific polymetallic nodule fields
Provedor de dados: 5
Autores: Błażewicz, Magdalena; Jóźwiak, Piotr; Menot, Lenaick; Pabis, Krzysztof.
The benthic fauna associated with polymetallic nodule fields is scarcely studied. Studies on species richness and distribution patterns are indispensable for the conservation of the abyssal ecosystem and for the development of management strategies for sustained commercial activities in the future. Here, we analysed the distribution patterns and diversity of tanaidacean communities associated with four International Seabed Authority licenced areas (BGR, IOM, GSR, Ifremer) located in the Clarion-Clipperton Fracture Zone (North-East equatorial Pacific) and the one Area of Particular Environmental Interests (APEI3). The study was based on 34 box core samples collected at depths ranging from 4,200 to 5,000 m. Altogether, 98 species (446 individuals) were...

Genetic Characterization of Cupped Oyster Resources in Europe Using Informative Single Nucleotide Polymorphism (SNP) Panels
Provedor de dados: 5
Autores: Lapegue, Sylvie; Heurtebise, Serge; Cornette, Florence; Guichoux, Erwan; Gagnaire, Pierre-alexandre.
The Pacific oyster, Crassostrea gigas, was voluntarily introduced from Japan and British Columbia into Europe in the early 1970s, mainly to replace the Portuguese oyster, Crassostrea angulata, in the French shellfish industry, following a severe disease outbreak. Since then, the two species have been in contact in southern Europe and, therefore, have the potential to exchange genes. Recent evolutionary genomic works have provided empirical evidence that C. gigas and C. angulata exhibit partial reproductive isolation. Although hybridization occurs in nature, the rate of interspecific gene flow varies across the genome, resulting in highly heterogeneous genome divergence. Taking this biological property into account is important to characterize genetic...

Autores: Eymard, Sylvie.
Critical steps of the process of horse mackerel surimi manufacturing were identified. This led to propose technical and chemical solutions in order to limit development of lipid oxidation reactions. In this way, analytical methods of lipids and lipid oxidation compounds were adapted to the studied products. A method to determine hydroperoxyde concentrations was developed. The front face fluorescence technique was tested to evaluate the degree of surimi alteration. Lipid oxidation kinetics were determined during horse mackerel storage on ice or at 17°C. The formation of lipid oxidation products was followed during manufacturing and horse mackerel surimi frozen storage. The impact of raw material freshness on the development of lipid oxidation during surimi...

Sex, size and timing: Sampling design for reliable population genetics analyses using microsatellite data
Provedor de dados: 5
Autores: Dubois, Quentin; Lebigre, Christophe; Schtickzelle, Nicolas; Turlure, Camille.
Population genetics is used in a wide variety of fields such as ecology and biodiversity conservation. How estimated genetic characteristics of natural populations can be influenced by the sampling design has been a long-standing concern. Multiple simulation and empirical studies illustrated the influence of both sample size and polymorphism of markers. However, our review of studies on butterfly population genetics indicates no consensus on sample size for the estimation of genetic diversity or differentiation. Furthermore, other aspects of sampling design (sex ratio and timing of sampling) were not addressed and their potential impact on genetic parameter estimates rarely explored. Using a large empirical dataset (with spatial and temporal replicates)...

Fish wariness is a more sensitive indicator to changes in fishing pressure than abundance, length or biomass
Provedor de dados: 5
Autores: Goetze, Jordan S.; Januchowski-hartley, Fraser A.; Claudet, Joachim; Langlois, Tim J.; Wilson, Shaun K.; Jupiter, Stacy D.
Identifying the most sensitive indicators to changes in fishing pressure is important for accurately detecting impacts. Biomass is thought to be more sensitive than abundance and length, while the wariness of fishes is emerging as a new metric. Periodically harvested closures (PHCs) that involve the opening and closing of an area to fishing are the most common form of fisheries management in the western Pacific. The opening of PHCs to fishing provides a unique opportunity to compare the sensitivity of metrics, such as abundance, length, biomass and wariness, to changes in fishing pressure. Diver-operated stereo video (stereo-DOV) provides data on fish behavior (using a proxy for wariness, minimum approach distance) simultaneous to abundance and length...

Shellfish farming and coastal zone management (CZM) development in the Marennes-Oleron Bay and Charentais Sounds (Charente Maritime, France): A review of recent developments
Provedor de dados: 5
Autores: Goulletquer, Philippe; Le Moine, Olivier.
France is currently one of the leading shellfish production countries in Europe, harvesting more than 150,000 metric tons of the Pacific cupped oyster (Crassostrea gigas) and 60,000 tons of mussels (Mytilus edulis and M. galloprocincialis) each year. Among rearing areas, the Charentais Sounds and the Marennes-Oleron Bay rank first in Europe, with an annual production of 40,000 and 15,000 tons of oysters and mussels respectively. More than a third of French production is marketed from the Marennes-Oleron area. As natural C. gigas and M. edulis spatfall is limited to the Atlantic coast, the Marennes-Oleron Bay and the Charentais Sounds play a critical role nationally, representing more than half of French oyster and mussel spat production. The stocking...

Linking life-history traits, spatial distribution and abundance of two species of lugworms to bait collection: A case study for sustainable management plan
Provedor de dados: 5
Autores: De Cubber, Lola; Lefebvre, Sebastien; Fisseau, Charline; Cornille, Vincent; Gaudron, Sylvie Marylene.
Arenicola spp. are marine benthic polychaetes dug for bait by anglers. Without regulation, this activity can lead to the decrease of lugworms' population meanwhile affecting the physical characteristics of the beach and the biodiversity. Here, we identified through morphology and genetics two species of lugworms, Arenicola marina and A. defodiens, within a Marine Protected Area of the Eastern English Channel (France). For each species, abundance and spatial distribution were assessed using a stratified random sampling and interpolation at four studied sites, as well as some life-history traits. These data were compared to lugworms' collection data to estimate its sustainability and to provide potential management measures. At one site, A. marina was...

Coral reefs are under threat and innovative management strategies are urgently required. However, discoveries from innovative fields of coral reef research are rarely transposed in practical conservation actions. This is mainly due to the difficulties in knowledge exchange between scientists and conservation stakeholders. The ManaCo consortium (http://manaco.ird.nc/) is an international network federating conservation stakeholders and researchers in a common effort to preserve the coral reefs. The focus is on using modern tools to build a bridge between indigenous knowledge and scientific innovation.

Autores: Robinet, Tony; Feunteun, Eric; Keith, Philippe; Marquet, Gérard; Olivier, Jean-michel; Reveillac, Elodie; Valade, Pierre.
Anguillid eels were sampled from permanent rivers in the Reunion and Mauritius islands, western Indian Ocean, with a standardized electrofishing method. A. marmorata was very dominant, corresponding to 91.7 and 90.7% of all the eels collected in Reunion and Mauritius, respectively. Three other species (A. mossambica, A. bicolor bicolor and A. nebulosa labiata) were also present in both islands. A. marmorata showed a strong altitudinal gradient of densities from the lower to upper zones, especially in the younger stages (TL &lt; 250 mm), while A. mossambica was only found in the upper zones and A. bicolor bicolor occurred only in the lower zones (A. nebulosa labiata was rare).

Large-scale genetic panmixia in the blue shark (     Prionace glauca     ): a single worldwide population, or a genetic lag-time effect of the “grey zone” of differentiation?
Provedor de dados: 5
Autores: Bailleul, Diane; Mackenzie, Alicia; Sacchi, Olivier; Poisson, Francois; Bierne, Nicolas; Arnaud-haond, Sophie.
The blue shark Prionace glauca, among the most common and widely studied pelagic sharks, is a top predator, exhibiting the widest distribution range. However, little is known about its population structure and spatial dynamics. With an estimated removal of 10 to 20 million individuals per year by fisheries, the species is classified as “Near Threatened” by International Union for Conservation of Nature. We lack the knowledge to forecast the long-term consequences of such a huge removal on this top predator itself and on its trophic network. The genetic analysis of more than 200 samples collected at broad scale (from Mediterranean Sea, North Atlantic and Pacific Oceans) using mtDNA and nine microsatellite markers allowed to detect signatures of genetic...

Motivation Traits are increasingly being used to quantify global biodiversity patterns, with trait databases growing in size and number, across diverse taxa. Despite growing interest in a trait-based approach to the biodiversity of the deep sea, where the impacts of human activities (including seabed mining) accelerate, there is no single repository for species traits for deep-sea chemosynthesis-based ecosystems, including hydrothermal vents. Using an international, collaborative approach, we have compiled the first global-scale trait database for deep-sea hydrothermal-vent fauna - sFDvent (sDiv-funded trait database for the Functional Diversity of vents). We formed a funded working group to select traits appropriate to: (a) capture the performance of vent...

Nature-Based Tourism Elicits a Phenotypic Shift in the Coping Abilities of Fish
Provedor de dados: 5

Nature-based tourism is gaining extensive popularity, increasing the intensity and frequency of human-wildlife contacts. As a consequence, behavioral and physiological alterations were observed in most exposed animals. However, while the majority of these studies investigated the effects of punctual exposure to tourists, the consequences of constant exposition to humans in the wild remains overlooked. This is an important gap considering the exponential interest for recreational outdoor activities. To infer long-term effects of intensive tourism, we capitalized on Odontostilbe pequira, a short-lived sedentary Tetra fish who spends its life close to humans, on which it feeds on dead skin. Hence, those fish are constantly exposed to tourists throughout their...

Understanding variations in habitat use through time contributes to identification of habitats critical for species survival. Here we used passive acoustic telemetry to examine the residency and site fidelity patterns of the reef manta ray Mobula alfredi at Lady Elliot Island (LEI), a key aggregation site in eastern Australia. Six acoustic receivers were moored around LEI between 2009 and 2012, and 34 acoustic transmitters were deployed on manta rays. All tagged animals returned to this site within their recording period, with some individuals visiting the area for up to 23 consecutive days. Using a set of mixed effect models, we analysed the hourly visitation patterns of manta rays in relation to temporal and environmental variables. Diel phase and sea...

Human activities induce direct or indirect selection pressure on natural population and may ultimately affect population’s integrity. While numerous conservation programs aimed to minimize human‐induced genomic variation, human‐induced environmental variation may generate epigenomic variation potentially affecting fitness through phenotypic modifications. Major questions remain pertaining to how much epigenomic variation arises from environmental heterogeneity, whether this variation can persist throughout life, and whether it can be transmitted across generations. We performed whole genome bisulfite sequencing (WGBS) on the sperm of genetically indistinguishable hatchery and wild born migrating adults of Coho salmon (Oncorhynchus kisutch) from two...

Genomics and telemetry suggest a role for migration harshness in determining overwintering habitat choice, but not gene flow, in anadromous Arctic Char
Provedor de dados: 5
Autores: Moore, Jean-sebastien; Harris, Les N.; Le Luyer, Jeremy; Sutherland, Ben J. G.; Rougemont, Quentin; Tallman, Ross F.; Fisk, Aaron T.; Bernatchez, Louis.
Migration is a ubiquitous life history trait with profound evolutionary and ecological consequences. Recent developments in telemetry and genomics, when combined, can bring significant insights on the migratory ecology of non-model organisms in the wild. Here, we used this integrative approach to document dispersal, gene flow and potential for local adaptation in anadromous Arctic Char from six rivers in the Canadian Arctic. Acoustic telemetry data from 124 tracked individuals indicated asymmetric dispersal, with a large proportion of fish (72%) tagged in three different rivers migrating up the same short river in the fall. Population genomics data from 6,136 SNP markers revealed weak, albeit significant, population differentiation (average pairwise FST =...

Autores: Murgier, Juliette; Mclean, Matthew; Maire, Anthony; Mouillot, David; Loiseau, Nicolas; Munoz, François; Violle, Cyrille; Auber, Arnaud.
Functionally distinct species (i.e. species with unique trait combinations in the community) can support important ecological roles and contribute disproportionately to ecosystem functioning. Yet, how functionally distinct species have responded to recent climate change and human exploitation has been widely overlooked. Here, using ecological traits and long-term fish data in the North Sea, we identified functionally distinct and functionally common species, and evaluated their spatial andtemporaldynamics in relation to environmental variables and fishing pressure. Functionally distinct specieswere characterized by late sexualmaturity, few, large offspring, and high parental care,many being sharks and skates that play critical roles in structuring food...

Morphometric Differentiation of Two Nigerian Fish Species (Oreochromis niloticus and Lates niloticus) Using Principal Components and Discriminant Analysis
Provedor de dados: 77
Autores: Yakubu,A; Okunsebor,S. A.
Morphological differences between two close fish populations were investigated in Doma Dam, north central Nigeria using principal component and discriminant analyses. The purpose was to identify the two species correctly and assign them into distinct genetic groups. To achieve this, seven morphometric measurements (body weight, standard length, total length, head length, body depth, dorsal fin length and caudal fin length) were made on each of the studied 252 fish specimens (153 Oreochromis niloticus and 99 Lates niloticus). The analysis of variance showed that significantly (P&lt;0.05) higher values were recorded for Lates niloticus in all the body traits examined, except dorsal fin length. From the principal component analysis, the differences between...

Morphometric characteristics and seasonal proximity to water of the Cypriot bluntnosed viper Macrovipera lebetina lebetina (Linnaeus, 1758)
Provedor de dados: 80
Autores: Jestrzemski,Daniel; Kuzyakova,Irina.
Abstract  Background: The blunt-nosed viper Macrovipera lebetina (Linnaeus, 1758) is a medically important snake species in the Middle East. Its nominate subspecies Macrovipera l. lebetina is confined to Cyprus, where it is the only dangerously venomous snake species and heavily pursued. Despite the viper's large size, data on its body mass and sex-specific morphological differences are scarce. It is commonly believed that M. l. lebetina prefers freshwater proximity during summer. Hence, we aimed at investigating M. l. lebetina sex-specific morphological differences and its possible attraction to freshwater bodies in late summer.  Methods: Morphometric characteristics, proximity to water and conservation status of M. l. lebetina were investigated in Paphos...

Collection records of Gyldenstolpia planaltensis (Avila-Pires, 1972) (Rodentia, Cricetidae) suggest the local extinction of the species
Provedor de dados: 81
Autores: Bezerra,Alexandra M. R.
The genus Gyldenstolpia was recently described and includes two species, G. fronto and G. planaltensis, both very rare. Gyldenstolpia planaltensis had records in only two localities in the central-western Brazil and is endemic to the Cerrado biome. A new locality is added to G. planaltensis, extending its distribution, and was obtained from a specimen housed in a museum collection. Summarized data on the distribution, ecology and natural history of G. planaltensis denotes that this species can be already extinct or committed to extinction because of habitat conversion and habitat loss.

Bats of Saint Martin, French West Indies/Sint Maarten, Netherlands Antilles
Provedor de dados: 81
Autores: Genoways,Hugh H.; Pedersen,Scott C.; Larsen,Peter A.; Kwiecinski,Gary G.; Huebschman,Jeffrey J.
Six species of bats have been previously reported from the Antillean island of Saint Martin/Sint Maarten- Artibeus jamaicensis, Brachyphylla cavernarum, Molossus molossus, Tadarida brasiliensis, Noctilio leporinus, and Myotis nigricans nesopolus. Our field research reported herein documents an additional three species of bats from the island for the first time- Monophyllus plethodon, Ardops nichollsi, and Natalus stramineus. Re-examination of the single voucher of Myotis nigricans nesopolus has led us to exclude this species from the fauna of Saint Martin/Sint Maarten. Based on our field research and the study of specimens housed in museum collections, we present information on the eight species of bats that we have documented as occurring on Saint...

On a collision course: the vulnerability of bats to roadkills in Brazil
Provedor de dados: 81
Autores: Novaes,Roberto Leonan M; Laurindo,Rafael S; Dornas,Rubem A. P; Esbérard,Carlos Eduardo L; Bueno,Cecília.
In Brazil, studies on roadkills are recent and usually restricted to lists of species found at some road stretch. Among mammals, medium- and large-sized species have received greater attention. The present study aimed at presenting the first list of bat roadkills in Brazil, including comments on the traits that may cause roadkills. We recorded 415 deaths from 44 species of seven families in all Brazilian biomes. We did not observe a relationship between body size or type of flight with the number of bat-vehicle collisions. Frugivore was the trophic guild most victimized, possibly due to greater natural abundance, foraging in low height airspace, and capacity to make long-distance movements. The elevated number of species recorded indicates that these roads...

A preliminary revision of knowledge status of felids in Argentina
Provedor de dados: 81
Autores: Lucherini,Mauro; Soler,Lucía; Luengos Vidal,Estela.
Argentina is the host of 10 wild felids (28% of the world total). Although the Cat Specialist Group Action Plan has classified the conservation status of Argentine cats as relatively good, the ranking was based on a largely incomplete database for at least 80% of the species. Here we review the current status of knowledge and research effort of Argentine cats, compare it with their distribution, habitat association and conservation status and provide guidelines for their future research. Between 1990 and 2000, cat research has received increasing attention in Argentina. Twenty-four projects have been carried out, but only 13 studies are still in progress. A rank of research priority has been calculated for each felid and ecoregion. Our analysis showed that...

Autores: Oliveira,Roniel F; Hannibal,Wellington.
We evaluated the effect of patch attributes on the richness of medium- and large-sized mammals in semi-deciduous forest patches in the southern of Goiás state, Brazil. We surveyed 14 semi-deciduous for­est patches (35 to 869 ha) from January to December 2015. Medium- and large-sized mammal were sampled through direct observation, tracks, feces and burrows. In each semi-deciduous forest patch, we measured total area and core area (in hectare), degree of isolation (in meters) and connectivity (patches connected to riparian forest versus isolated patches). We recorded 22 species of medium- and large-sized mammals. Species richness was positively related to the core area of the patches. Patch size had a significant influence on species richness showing that...

Lonchophylla bokermanni is known from three localities in the southern portion of the Serra do Espinhaço, all located in the Cerrado of Minas Gerais. Based on recent material from two localities in the Caatinga of Bahia, northeastern Brazil, we report the species occurrence in the northern portion of Serra do Espinhaço. These new records extend the species distribution by more than 840 km and represent the first records of L. bokermanni in the Caatinga biome. The localities we report here are under severe anthropic pres­sure, and this distribution extension should not inhibit conservation efforts for the species.

Autores: Utteridge, T.M.A.; Edwards, P.J.
The highest mountains in South-East Asia are in the Sudirman range of Indonesian New Guinea; the highest is Mt Jaya which rises to 4 884 m and is still partly glaciated. The geological history of the region has left it rich in mineral deposits and the alpine area is currently being mined for copper. In 1997 a project was initiated by the Royal Botanic Gardens, Kew, in conjunction with the mining companies Rio Tinto and PT-Freeport Indonesia, to study the region’s flora. An introduction to the region, including geology, glaciation and past exploration will be given, as well as the history and objectives of the Kew project. During the project, Kew made several collaborative expeditions to the area, as well as a database of all historical collections from Mt...

Provedor de dados: 16
Autores: Barcelona, J.F.; Pelser, P.B.; Cajano, M.O.
A new small-flowered species of Philippine Rafflesia from Mt Banahaw in Luzon is described. Rafflesia banahaw is the seventh endemic species of Rafflesia found in the Philippines. It resembles R. baletei, but is different in, amongst other characters, having more confluent wart ornamentations, more numerous and densely packed processes on the disk, and more numerous, slightly immersed anthers. In addition, R. banahaw has glabrous ramenta which are grouped in dense clusters on the inside of the diaphragm and are more or less solitary on the inside of the perigone tube, whereas the ramenta of R. baletei are pubescent and distributed more uniformly.

Malleefowl conservation in New South Wales: a review
Provedor de dados: 16
Autores: Priddel, D.; Wheeler, R.
Together with land clearance, grazing by stock and inappropriate fire regimes, predation by the introduced European red fox Vulpes vulpes (Linnaeus, 1758) has decimated populations of malleefowl Leipoa ocellata Gould, 1840. The decline of the malleefowl has been most pronounced in New South Wales, where foxes prey so heavily on malleefowl that adult mortality exceeds recruitment of young into the breeding population. Although young malleefowl are particularly vulnerable to foxes, subadults and adults are also taken. Within New South Wales, heavy predation by foxes occurs both in the remnants of native vegetation within agricultural lands and in the large tracts of mallee that lie further inland. Foxes appear to be the prime cause of malleefowl mortality...

Individual, local and subspecific variation in female Hermann’s tortoise (Testudo hermanni) reproductive characters
Provedor de dados: 16
Autores: Longepierre, S.; Grenot, C.; Hailey, A.
We studied reproductive characters of a population of the tortoise Testudo h. hermanni in the Plaine des Maures (Var), and compared these to another population in southern France and to T. h. boettgeri in Greece. Clutch characters, which are measures of total reproductive investment, showed no differences between subspecies or sites after body size correction by ANCOVA. Egg characters, which measure the division of this investment among offspring, did vary significantly among both subspecies and sites after correcting for body mass. The presence of such local variation should discourage relocation of the threatened T. h. hermanni even between populations of the same subspecies.

A new species of Hymenostegia (Detarieae, Caesalpinioideae, Leguminosae) is described from Cameroon. Hymenostegia viridiflora has previously been confused with the type species of the genus, H. floribunda, but differs from it in having pale green to greenish yellow instead of lemon yellow petals, a broader upper part of the stipule, more numerous reddish veins on the white bracteoles and generally more numerous and narrower leaflets. As a consequence, the geographic range of true H. floribunda no longer includes Cameroon. Hymenostegia viridiflora is assessed as Vulnerable according to the criteria of IUCN.

Autores: Chow, Barbara A.
CHOW, Barbara A., 1997. Biological and management aspects of a Caribbean mangal: West Harbour, Jamaica. Studies Nat. Hist. Caribbean Region 73, Amsterdam, 1997: 1-22. Observations are given for the first time of West Harbour, a pristine south-coast Jamaican mangal. West Harbour is shown to be a diverse and extensive mangal (22.5 km²) with a high degree of representativeness with respect to mangrove community types. The classical mangrove zonation is evident, a fringing seaward almost mono-specific Rhizophora fronting backswamp basin Avicennia. Mangrove community types are varied; overwash, fringe, basin and scrub Rhizophora, and basin and scrub Avicennia. A broad scale survey recorded a total of 45 plant and 183 macrofaunal components of the biota which...

The National Malleefowl Recovery Plan: a framework for conserving the species across Australia
Provedor de dados: 16
Autores: Benshemesh, J.
The malleefowl Leipoa ocellata Gould, 1840, has declined substantially since European settlement of Australia just over 200 years ago. The species is now vulnerable and is threatened by the loss and degradation of suitable habitat by grazing, fire, and clearing, by the insidious effects of fragmentation of their populations that has resulted from clearing, and by predation by introduced foxes. Accordingly, a National Malleefowl Recovery Plan is being prepared to outline actions that are needed to both secure the species and provide the information necessary for effective management. Conserving malleefowl will require improved management throughout its range and on a diversity of land tenures. Improving habitat quality is crucial and may be achieved by...

Autores: Nijman, V.; Shepherd, C.R.
In 1973 the Convention in International Trade in Endangered Species of Wild Fauna and Flora (CITES) was called to life as to regulate the international wildlife trade, and to prevent species becoming (economically and biologically) extinct. The trade in freshwater turtles and tortoises in Asia is so huge that it threatens the survival of many species. In 2006 and 2007, during three surveys at Chatuchak market in Bangkok, Thailand, we recorded a significant trade in non-native CITES-listed freshwater turtles and tortoises to be used as pets. We documented a total of 688 individuals of 19 species from different regions of the world, many of which are globally threatened with extinction. Most commonly recorded were three species of tortoise from Madagascar...

A conservation genetic study of Rafflesia speciosa (Rafflesiaceae): patterns of genetic diversity and differentiation within and between islands
Provedor de dados: 16
Autores: Pelser, P.B.; Nickrent, D.L.; Barcelona, J.F.
Rafflesia speciosa is a threatened endo-holoparasitic species. It has several populations in the Central Panay Mountain Range (CPMR) of Panay island and a single population on Negros Island. Because R. speciosa is the only Philippine species of the genus that is not endemic to an individual island, it is a suitable species for improving our understanding of the factors underlying the high island endemism of Philippine Rafflesia. For this purpose and to inform the conservation management of R. speciosa, patterns of genetic diversity and differentiation were studied using 15 microsatellite loci and samples from nine populations. None of these populations shows evidence of inbreeding and R. speciosa has similar levels of heterozygosity as generally observed...

To date, a total of 288 species from 96 genera were identified from the limestone areas in Perlis and Padawan-Bau, Sarawak, of which many of these are restricted to limestone habitat and either endemic to Perlis or to Sarawak. Knowledge and data obtained from the field observation over the past 8 years leads us to report that at least 15 species endemic to limestone has become rare in the wild in Perlis, Bau and Padawan Sarawak. This was mainly attributed by: i) lack of emphasis by the government on understanding and protecting biodiversity in this kind of habitat; ii) lack of scientists willing to do research in dangerous and disaster prone limestone habitat; and iii) lack of knowledge and awareness among local communities on the importance of conserving...

Effects of habitat disturbance and hunting on the density and the biomass of the endemic Hose’s leaf monkey Presbytis hosei (Thomas, 1889) (Mammalia: Primates: Cercopithecidae) in east Borneo
Provedor de dados: 16
Autores: Nijman, Vincent.
Hose’s leaf monkey Presbytis hosei is endemic to Borneo and occurs only in tall forest. In recent decades Borneo has lost a large part of its forest cover, mostly in low-lying coastal regions. Large intact tracts of forest remain in the interior, but these are by and large inhabited by tribes that subsist in part by hunting. The combined effects of habitat disturbance and hunting on the densities and biomass of Hose’s leaf monkey were studied in Kayan Mentarang National Park in Borneo’s far interior. Over four months, data on densities and hunting were collected by transect walks in four forest types. Hose’s leaf monkeys were hunted to deter crop-raiding, for their meat, and to obtain bezoar stones (visceral secretions used in traditional medicine). Hose’s...

The occurrence of Digitivalva arnicella in the Netherlands: rediscovery and conservation (Lepidoptera: Plutellidae: Acrolepiinae)  Digitivalva arnicella (Heyden, 1863), previously only known from two localities before 1902, has been rediscovered in eight localities in the northern part of the Netherlands (province of Drenthe) on its host Arnica montana. On the basis of leafmines, found in old herbarium collections, it can be concluded that the species was once widespread within the range of its host in the northern and eastern parts of the Netherlands and has apparently been overlooked by entomologists since. D. arnicella is a much endangered species in the Netherlands, because of the dramatic decline of its host. Two of the eight discovered populations...

Megapodes: an action plan for their conservation 1995 - 1999, a collaborative effort of members of the Megapode Specialist Group and the World Pheasant Association, was published in 1995. It summarizes the conservation status of all megapode taxa and indicates the needs of those species under threat. The Action Plan was intended to be a stimulus for conservation orientated studies and to generate funds more easily.   An overview is given of studies (1990 - present) in which these threatened taxa were involved. The status of these and other taxa are reassessed according to the finalized IUCN threat categories (which supercede the Mace-Lande threat categories originally used in the Action Plan) as a preparation for the megapode action plan 2000 - 2004.

Recent changes in distribution of dragonflies in Switzerland (Odonata)   In 1998 the Swiss Centre for the Cartography of Fauna (CSCF) initiated ‘Odonata 2000’. This project aimed at testing a method for periodical reassessment of Red Lists in Switzerland. The study was carried out on Odonata and consisted of the resampling of known localities of threatened species and the sampling of new localities. Based on the number of sites where a given species has been found in the periods 1970-1998 and 1999-2000, trends were calculated for each species. The results show that since 1994 three species have disappeared from Switzerland, nine species have declined, two species have increased and 64 species have remained stable.

Butterflies for the new millennium: mapping butterfly distributions in Britain (Lepidoptera)   Butterflies for the New Millennium is the largest and most comprehensive survey of butterfly distribution ever undertaken in Britain and Ireland. The number of contributing recorders, the coverage achieved and the number and quality of distribution records generated far exceed those available for any other invertebrate taxon. The data thus provide a unique insight into the effects of habitat degradation and climate change on a high profile insect group. The results of the first five years of the survey (1995-1999) have been analysed to assess broad-scale distribution changes over the past two decades and the past two centuries. In both time periods, the British...

Shelters such as leaf nests, tree holes or vegetation tangles play a crucial role in the life of many nocturnal mammals. While information about characteristics and availability of these resources may help in conservation planning, nest use gives an indication about a species’ social organisation. The northern giant mouse lemur (Mirza zaza) is threatened by habitat loss within its restricted range. Our aim was to examine nest site preferences of M. zaza and to explore the species’ social organisation by examining sleeping site aggregation size and genetic relatedness within and between such aggregations.

Unexpected diversity of slow lorises (Nycticebus spp.) within the Javan pet trade: implications for slow loris taxonomy
Provedor de dados: 16
Autores: Nekaris, K.A.I.; Jaffe, S.
Since the 1950s, Sundaland (Borneo, Java, Sumatra and their surrounding islands) was thought to be inhabited by a single slow loris species, the greater slow loris Nycticebus coucang. Early taxonomies as well as recent morphological and genetic studies, however, point to at least three species native to this region: N. coucang, N. menagensis, and N. javanicus. In the light of this taxonomy, all Sundaland slow lorises, previously considered Least Threatened, have been listed as Vulnerable or Endangered. Of particular concern is the fact that slow lorises are the most common protected primate species in the rampant Southeast Asian pet trade, resulting in their recent transferral to CITES Appendix I precluding all international commercial trade.

What we don’t know about megapodes
Provedor de dados: 16
Autores: Jones, D.N.
While the growth in megapode studies has been extraordinary, much remains to be done. Further work is especially crucial if the many conservation projects that are planned and underway are to be based on a sound and reliable base of understanding. Thus, the ten projects proposed here are not directly conservation-orientated. Rather, they are aimed at elucidating aspects and issues that are needed for a more complete understanding of these remarkable birds. In particular, a plea is made for high quality natural history and for cultural sensitivity and awareness.

Orchid bee fauna (Hymenoptera: Apidae: Euglossina) of Atlantic Forest fragments inside an urban area in southeastern Brazil
Provedor de dados: 82
Autores: Nemésio,André; Silveira,Fernando A.
Male orchid bees were collected by chemical baiting in four forest fragments in parks of the city of Belo Horizonte, Minas Gerais, southeastern Brazil. One thousand three hundred and twenty-five males belonging to 14 species were captured within one year. The capture data were compared through correlation tests. The data suggest that abundance of orchid bees tend to increase with fragment size, although no correlation between species richness and fragment size was obtained. The results presented herein suggest that forest fragments in a large city may be of importance concerning conservation of orchid-bee faunas.

Biogeographic notes on rare species of Euglossina (Hymenoptera: Apidae: Apini) occurring in the Brazilian Atlantic Rain Forest
Provedor de dados: 82
Autores: Nemésio,André; Silveira,Fernando A.
The significance of specimens of rare species of Euglossina collected recently is discussed in terms of elucidating their biogeography and conservation status. Particularly, two new records are presented for the state of Minas Gerais, which considerably increase the known geographic range of the species they represent. These are a male of Eufriesea aeneiventris (Mocsáry), last recorded in 1943, which was attracted to methyl salicylate at the Parque Estadual do Rio Doce, and a male of Eulaema seabrai collected on flowers in the urban area of Sabará. This is also the first record for this species in the state.

Edge effects on the orchid-bee fauna (Hymenoptera: Apidae) at a large remnant of Atlantic Rain Forest in southeastern Brazil
Provedor de dados: 82
Autores: Nemésio,André; Silveira,Fernando A.
Male orchid bees were sampled with chemical baits monthly from July 1999 to April 2000 at six sites situated at different distances from the forest edge (0 to 4,000 m) at Parque Estadual do Rio Doce, the largest remnant of Atlantic Forest in the state of Minas Gerais, southeastern Brazil. The main goal of this study was to assess the abundance, richness, and the community structure of the orchid-bee fauna at different distances from the edge. In all, 1,183 males from 20 species were collected. Only minor and insignificant variation in richness and abundance were observed among the sites. Two dominant species, Euglossa analis Westwood (Hymenoptera: Apidae) and Eulaema cingulata (Fabricius) (Hymenoptera: Apidae), showed strongly opposing habitat...

Diversity of bees and their floral resources at altitudinal areas in the Southern Espinhaço Range, Minas Gerais, Brazil
Provedor de dados: 82
Autores: Araújo,Vinícius A.; Antonini,Yasmine; Araújo,Ana P.A.
The Southern Espinhaço Range consists of large areas covered by quartzitic or metaliferous tropical altitudinal fields. The Espinhaço Range ecosystems are endangered by anthropic high impacts, particularly due to mining and urbanization. We conducted a one-year inventory of the bee flora and fauna at the quartzitic Ouro Branco Mountains and a two-year survey of the metaliferous Ouro Preto fields. The samples were collected twice a month, from 8:00 am to 5:00 pm. The bees (677) belonged to 91 species, five families. The family Apidae was the richest and most abundant, followed by the Halictidae and Megachilidae. The bees visited 46 flowering plant species; the most visited plants were the Asteraceae (n = 220), the Malpighiaceae (n = 95), the Melastomataceae...

Diversity and distribution of orchid bees (Hymenoptera: Apidae) with a revised checklist of species
Provedor de dados: 82
Autores: Nemésio,André; Silveira,Fernando A.
The aim of this study was to investigate the diversity and distribution patterns of orchid bees (Euglossina). Cluster and correlation analyses were applied to data extracted from 28 orchid-bee surveys throughout the Neotropical Region. The 28 sampling sites were grouped in three main biogeographic areas that roughly correspond to the Amazonian Basin, the Atlantic Forest and Central America. These three regions, as well as subregions within each of them, correspond approximately to biogeographic components identified through phylogeny-based analyses for other bees and organisms. The Amazonian Forest as a whole has the richest fauna and the highest levels of endemism. The Atlantic Forest, on the other hand, showed the poorest fauna and the lowest levels of...

Forest fragments with larger core areas better sustain diverse orchid bee faunas (Hymenoptera: Apidae: Euglossina)
Provedor de dados: 82
Autores: Nemésio,André; Silveira,Fernando A.
Male orchid bees were attracted to chemical baits and collected in nine Atlantic Forest fragments in southeastern Brazil. Fragments differed in size and shape. Three additional sites were also sampled in a nearby large fragment. Three hypothetical core areas of each fragment were measured as the total area minus an area of 50, 100, and 200-m-wide perimeter. Abundance and richness were not correlated with either fragment size or ratio area/perimeter, but were positively correlated with the size of core areas. These results suggest that orchid bee conservation requires the preservation of the fragments with the largest possible core areas. Neither size nor shape alone (area/perimeter ratio) seemed to be good indicators of the value of a given fragment for...

Provedor de dados: 83
Autores: Carmo,Wanessa P. D.; Fávaro,Luís Fernando; Coelho,Rui.
ABSTRACT Age and growth studies are fundamental to successful fisheries management. Zapteryx brevirostris (Müller &amp; Henle, 1841) is distributed off the Brazilian continental shelf and this species is assessed as “Vulnerable” in the Red List of the International Union for the Conservation of Nature (IUCN). Thus, the objective of this study was to present previously unknown information about the age and growth of Z. brevirostris that can be used for its management, conservation, and fisheries. A total of 162 specimens were sampled, with total lengths (TL) varying between 35.7 cm and 56 cm. The vertebrae were embedded in resin, sectioned in cuts with 0.5 mm thickness and the growth bands of the vertebrae were read under a light microscope. In the studied...

Microsatellite variation and population genetic structure of a neotropical endangered Bryconinae species Brycon insignis Steindachner, 1877: implications for its conservation and sustainable management
Provedor de dados: 83
Autores: Matsumoto,Cristianne Kayoko; Hilsdorf,Alexandre Wagner Silva.
Piabanha (Brycon insignis) is a freshwater fish species from the drainages in Southeastern Brazil. During the 1950s, it was an important economic and food resource for local populations, but dramatic and continuous environmental degradation seriously jeopardized the B. insignis populations in the region. Microsatellite markers were used to assess the genetic structure of wild populations of B. insignis and compare the genetic variability and integrity of the wild populations with a captive population. Samples of DNA from 208 specimens from geographically isolated populations were analyzed. Population genetic structure was investigated using F ST, R ST estimates as well as AMOVA. All five loci used in this study were polymorphic with observed heterozygosity...

ABSTRACT Brycon nattereri is an endangered Neotropical fish reported along conserved stretches of the upper Paraná, Tocantins and São Francisco rivers. Populations of this species have been very rare in some Paraná River sub basins. This study analyzes the genetic diversity and population structure of B. nattereri in a restricted area of occurrence recently identified in upper Paraná River basin. Seven microsatellite loci and 497 bp of D-Loop mitochondrial region were examined in 92 individuals from four points along the area of occurrence. Both molecular markers indicated a single population distributed along a stretch of the river approximately 80 km long. Although some of the data suggest an ancient bottleneck, current levels of genetic diversity (H  E...

Reefs, mangroves and seagrass biotopes often occur in close association, forming a complex and highly productive ecosystem that provide significant ecologic and economic goods and services. Different anthropogenic disturbances are increasingly affecting these tropical coastal habitats leading to growing conservation concern. In this field-based study, we used a visual census technique (belt transects 50 m x 2 m) to investigate the interactions between fishes and microhabitats at the Mamanguape Mangrove-Reef system, NE Brazil. Overall, 144 belt transects were performed from October 2007 to September 2008 to assess the structure of the fish assemblage. Fish trophic groups and life stage (juveniles and adults) were recorded according to literature, the...

Autores: Bordignon,Carolina Rodrigues; Casatti,Lilian; Pérez-Mayorga,María Angélica; Teresa,Fabrício Barreto; Brejão,Gabriel Lourenço.
The functional structure of communities is commonly measured by the variability in functional traits, which may demonstrate complementarity or redundancy patterns. In this study, we tested the influence of environmental variables on the functional structure of fish assemblages in Amazonian streams within a deforestation gradient. We calculated six ecomorphological traits related to habitat use from each fish species, and used them to calculate the net relatedness index (NRI) and the nearest taxon index (NTI). The set of species that used the habitat differently (complementary or overdispersed assemblages) occurred in sites with a greater proportion of forests. The set of species that used the habitat in a similar way (redundant or clustered assemblages)...

A cave population of Isbrueckerichthys alipionis (Gosline, 1947) in the Upper Ribeira karst area, southeastern Brazil (Siluriformes: Loricariidae)
Provedor de dados: 83
Autores: Trajano,Eleonora; Secutti,Sandro; Pereira,Edson H. L.; Reis,Roberto E.
A cave population of the armored catfish Isbrueckerichthys alipionis is reported from the Santana Cave, in the rio Betari watershed, Upper Ribeira karst area, Iporanga, São Paulo State, southeastern Brazil. The cave population was compared to an epigean population of I. alipionis and no significant differences where found in morphology or degree of pigmentation. As the cave population is known for at least 30 years and is apparently isolated from epigean streams, it is classified as troglophilic. The discovery of this troglophilic species in the Santana Cave is an additional strong argument for the conservation of that cave.

This paper presents the results of the first analysis of the natural diet of Hippocampus reidi, one of the most sought after seahorse species in the international aquarium trade. Its main goals were to investigate food items and prey categories consumed by the species, and to discuss feeding strategy and inter and intra-individual components of niche breadth. Data were gathered from October 2005 to September 2006 at the Mamanguape estuary, State of Paraíba, NE Brazil. Food items from seahorses anaesthetized with clove oil were obtained by using a modified version of the flushing method, and were counted and identified to the lowest possible taxonomic level. Specimens were marked and had their height, sex, life and reproductive stage recorded, and then...

Autores: Vaini,Jussara Oliveira; Grisolia,Alexéia Barufatti; Prado,Fernanda Dotti do; Porto-Foresti,Fábio.
Hybrids of the species Pseudoplatystoma corruscansvs.Pseudoplatystoma reticulatum are extensively traded because they are more docile and precocious compared to their parents. This study aimed to identify the occurrence of hybrid 'Surubim' in rivers of the State of Mato Grosso do Sul, applying molecular techniques. Pseudoplatystoma corruscans, Pseudoplatystoma reticulatum and hybrid 'Surubim' were detected using multiplex PCR and PCR-RFLP in RAG2, GLOBIN, EF1α, 18S rRNA nuclear genes, and mitochondrial 16S rRNA gene. The results revealed the presence of F1 hybrids in rivers and the occurrence of genetic introgression, evidenced by the Post-F1 hybrids. Furthermore, discrepancies between the morphological and genetic identification were observed,...

Autores: Suzuki,Fábio Mineo; Pires,Lucas Vilela; Pompeu,Paulo Santos.
The objective of this study was to evaluate the passage of fish eggs and larvae through the Funil, Itutinga and Camargos Reservoirs, located in the upper Rio Grande basin, Minas Gerais, Brazil. Samples were taken downstream and upstream of the dams using a conical ichthyoplankton net and were collected every two weeks, twice per sampling day, between November 2008 and March 2009. Although eggs and larvae were abundant immediately upstream of the reservoirs, no ichthyoplankton were captured immediately downstream of the dams, possibly indicating that eggs and larvae do not pass through the reservoirs. The arrival of ichthyoplankton in the reservoirs without its effective passage downstream makes the survival of these eggs and larvae unlikely. Furthermore,...

ABSTRACT Mylesinus paucisquamatus is a threatened fish endemic to the rio Tocantins basin, with little information about its natural history. Using monitoring data obtained between 1998 and 2009, we investigated the spatial distribution, feeding and reproduction of this species in a long stretch of the middle-upper rio Tocantins. Eighty-one individuals were captured over a decade of intensive sampling. In addition, we recorded the species in only 13 out of 35 sites, particularly in the Tocantins and Paranã rivers. Most individuals were captured alone, while the remaining formed small groups. These results indicate that this fish is rheophilic and rare. We recorded seasonal variation in fish abundance, with higher values during the dry season, indicating...

Movement of Cichla species (Cichlidae) in a Venezuelan floodplain river
Provedor de dados: 83
Autores: Hoeinghaus,David J.; Layman,Craig A.; Arrington,D. Albrey; Winemiller,Kirk O.
In their native habitats of black- and clear-water Neotropical rivers, large predatory cichlids of the genus Cichla are an important food and recreational resource. Understanding patterns of movement for these species is necessary for effective management and conservation; however, no information is available on movement in natural fluvial populations. Therefore, we initiated a cooperative mark-recapture program with local sport-fishing groups to evaluate movement of Cichla in the Cinaruco River, Venezuela and to promote conservation awareness. Between January 1999 and May 2003, we tagged 2,224 individuals of three species of Cichla (C. temensis, C. orinocensis, and C. intermedia) with uniquely numbered floy tags. Over 52 months, 2.8% of the tagged fishes...

This paper provides a case study of a threatened seahorse species, Hippocampus reidi, highlighting the importance of using ecological information to assist conservation and management initiatives. Underwater visual sighting data (50 x 2m transect) gathered along the NE, SE and S portions of the Brazilian coast revealed an unequal distribution across localities, perhaps related to harvesting pressure, and a mean density of 0.026 ind.m-2. Our findings suggest some restricted spatial use by H. reidi, which was consistent with its estimated home range, and with re-sighting of specimens. Reproduction was recorded year-round, however productive peaks may exist. Components of habitat structure mostly used as anchoring points were mangrove plants, macroalgae,...

Deficient downstream passage through fish ladders: the case of Peixe Angical Dam, Tocantins River, Brazil
Provedor de dados: 83
Autores: Pelicice,Fernando Mayer; Agostinho,Carlos Sérgio.
Downstream passage through fish ladders and other facilities remains largely uninvestigated in South America. In view of this concern, we monitored ascending and descending fish movements through the fish ladder at Peixe Angical Dam, upper Tocantins River, Brazil, between September 2009 and August 2010. To investigate the extent of downstream passage, the fish fauna was sampled monthly (i) at sites upstream and downstream from the dam and (ii) inside the ladder. To distinguish between ascending and descending movements, the fish ladder remained open (permanent water flow), but a screen blocked the complete passage of fish in both directions. The results of the study indicated that the ladder restricts fish movements in both directions. Few species were...

Trophic ecology of Arapaima in Guyana: giant omnivores in Neotropical floodplains
Provedor de dados: 83
Autores: Watson,L. Cynthia; Stewart,Donald J.; Teece,Mark A.
Using stable nitrogen and carbon isotope signatures, we investigated the trophic ecology and identified potential prey fish groups supporting the giant Arapaima within floodplain lakes of the Essequibo River basin in southwestern Guyana. Morphological descriptions of feeding structures and digestive tract are presented together with preliminary data on Arapaima diets. Stable isotope results suggest that algivorous/detritivorous and omnivorous fishes contributed most to Arapaima biomass, and generally, that was consistent with what is known about Arapaima diets. Stable nitrogen isotope ratios for piscivorous fishes in these lakes were higher than nitrogen isotope ratios for Arapaima, indicating that piscivorous fishes are unlikely to constitute a major...

Provedor de dados: 83
Autores: Paiz,Leonardo M.; Baumgärtner,Lucas; Graça,Weferson J. da; Margarido,Vladimir P.; Pavanelli,Carla S.
ABSTRACT We provide cytogenetic data for the threatened species Gymnogeophagus setequedas, and the first record of that species collected in the Iguaçu River, within the Iguaçu National Park’s area of environmental preservation, which is an unexpected occurrence for that species. We verified a diploid number of 2n = 48 chromosomes (4sm + 24st + 20a) and the presence of heterochromatin in centromeric and pericentromeric regions, which are conserved characters in the Geophagini. The multiple nucleolar organizer regions observed in G. setequedas are considered to be apomorphic characters in the Geophagini, whereas the simple 5S rDNA cistrons located interstitially on the long arm of subtelocentric chromosomes represent a plesiomorphic character. Because G....

Fish passages in South America: an overview of studied facilities and research effort
Provedor de dados: 83
Autores: Lira,Nibelle A.; Pompeu,Paulo S.; Agostinho,Carlos S.; Agostinho,Angelo A.; Arcifa,Marlene Sofia; Pelicice,Fernando M.
ABSTRACT River regulation has fragmented fluvial ecosystems in South America, affecting fish migration and dispersion dynamics. In response, authorities have installed fish passage facilities (FPF) to mitigate impacts. However, little is known about the geographical distribution of these facilities, and no synthesis of the research effort applied to understanding their functioning and limitations exists. To address this issue, our study gathered the available scientific literature about fishways in South America to provide an overview of studied FPF and associated research effort. We found 80 studies that investigated 25 FPF, mostly ladders installed in the upper reaches of large rivers, particularly in the Paraná River Basin. One important finding is that...

Population size and survivorship for juvenile lemon sharks (Negaprion brevirostris) on their nursery grounds at a marine protected area in Brazil
Provedor de dados: 83
Autores: Freitas,Renato Hajenius Aché de; Rosa,Ricardo S.; Wetherbee,Bradley M.; Gruber,Samuel H.
Sharks face a number of obstacles for surviving their first several years of life and many species occupy nursery areas. Although estimates of survival, particularly for young age classes, are essential for assessing, monitoring and effectively managing animal populations, there have been relatively few calculations of survival within shark populations and even fewer estimates based on direct methods for sharks on their nursery grounds. We used tag-recapture methods to estimate the population size and survival of juvenile lemon sharks (Negaprion brevirostris) on their nursery grounds at Atol das Rocas, a marine protected area in Brazil. Sharks were sampled from1999 to 2003. Population size estimates ranged from 12 to 100 juvenile sharks and survival...

Autores: del Monte-Luna,Pablo; Castro-Aguirre,José Luis; Brook,Barry W.; de la Cruz-Agüero,José; Cruz-Escalona,Víctor Hugo.
All species of sawfish are listed by the International Union for the Conservation of Nature (IUCN) as endangered or critically endangered. In fact, the smalltooth sawfish Pristis pectinata, and the largetooth sawfish Pristis pristis, have been declared to be regionally and locally extinct from the US Atlantic coast and the Gulf of California, Mexico, respectively, likely due to overfishing. However, here we dispute these claims by illustrating how lack of existence of a given species within a region can be misconstrued as evidence for extinction.

Autores: Garcia-Trejo,Fernando; Hurtado-Gonzalez,Silvia Laura; Soto-Zarazúa,Genaro; Alatorre-Jacome,Oscar; Rico-García,Enrique; Gutiérrez-Yurrita,Pedro Joaquín.
Studies on the biological aspects of fish typically focus on species that currently have commercial value, causing species that lack such market value to be ignored. This is the case of several freshwater fish, specifically of several members of the Goodeidae family. In the State of Querétaro there are several species of this family characterized for being viviparous and having distinctive sexual dimorphism that may have commercial potential. The subject of this study is Girardinichthys multiradiatus, a viviparous fish endemic to the upper-half of the Lerma River basin. The lack of knowledge regarding its biology and ecology has prevented the development of guidelines to manage its habitat and to preserve its population. The objective was to determine the...

Relationships between water transparency and abundance of Cynodontidae species in the Bananal floodplain, Mato Grosso, Brazil
Provedor de dados: 83
Autores: Melo,Cesar Enrique de; Lima,Jane Dilvana; Silva,Eliete Francisca da.
The Cerrado in the Central Brazil is currently one of the most threatened ecosystems in the world. As a result, the aquatic habitats in this biome also undergo great impacts. Alterations related to land-use change increase sediment loadings in rivers, streams and lakes, resulting in sedimentation and decrease in water transparency. Water transparency determines underwater visibility conditions, and as a consequence fish assemblages respond to spatial and temporal changes in this variable. This work aimed to examine the influence of transparency on the abundance and distribution of Cynodontidae species, a visually oriented predatory fish group. Fish sampling was conducted in 15 sites located between Mortes and Araguaia rivers in the Bananal floodplain, Mato...

The troglobitic electric fish Eigenmannia vicentespelaea, endemic to a single cave-system and included in the Brazilian Red List of Threatened Fauna, was studied in relation to population densities and habitat. For comparison, we used the epigean species, E. trilineata. We verify if the population densities recorded for E. vicentespelaea follow the pattern observed for other subterranean fishes; if there are seasonal fluctuations in these densities and which environmental variables explain the densities variation. We estimated abundances and population densities during three consecutive dry seasons concomitant with habitat description and physicochemical variables measurements. For E. vicentespelaea: in six stream reaches in the São Vicente II cave. For E....

Autores: Bockmann,Flávio A.; Castro,Ricardo M. C.
Rhamdiopsis krugi, a new troglobitic heptapterid catfish, is described from the caves of Chapada Diamantina, State of Bahia, northeastern Brazil. This species, although frequently cited in the scientific literature along the last seventeen years, remained undescribed largely due to its uncertain phylogenetic affinities. The generic assignment of R. krugi was clouded largely by its high number of unusual morphological features (some related to cave life), for instance: absence of eyes and body pigmentation; presence of a widely exposed pseudotympanum; posterior border of the anterior branch and anterior margin of the arborescent portion of the posterior branch of the transverse process of fourth vertebra joined; dorsal hypural plate commonly with seven...

Tamaño, estructura y distribución estacional de poblaciones de aves acuáticas en el fiordo Ultima Esperanza y Canal Señoret, Región de Magallanes
Provedor de dados: 20
Autores: Guineo, Oscar; Garay, Gladys; Mutschke, Erika; Ríos, Carlos.
Between September 2001 and September 2002, Ultima Esperanza fjord and Señoret Channel were surveyed, sailing from Puerto Natales. Information on abundance, structure and distribution of aquatic and land birds observed during the sail is presented. We found 30 species of aquatic birds and 3 land birds.: 1 In Danger, 3 Vulnerables and 1 Insufficiently known. Our analysis shows that these fjords contained one of the biggest winter abundance of birds of the region and is a nesting area for many species. Furthermore, we proposed that the fjord constitute a core area for aquatic birds in summer when fresh water lagoons and ponds get dry. Finally, we make special reference to the need to implement a management plan in the area.

Autores: Torres, G.M.
Las playas arenosas son ambientes rigurosos donde los patrones comunitarios de macrofauna han sido relacionados con el tamaño de grano de arena, pendiente de la playa y procesos de ola/swash. Las relaciones entre la abundancia/diversidad de la macrofauna y morfodinámica de las playas micromareales de alta energía abiertas al mar dan pie a pensar un incremento de la abundancia/densidad desde playas con arena gruesa y fuerte pendiente hasta playas planas con arena fina y pendiente suave. Sin embargo, estas predicciones no han sido adecuadamente evaluadas cuando se trata de playas de baja energía protegidas, a pesar de que este tipo de playas es frecuente en la costa.

Between June and October 2002, six field assistants covered the Colombian Caribbean seashore gathering morphological, biotic and socio-cultural information, by direct observations and interviews with the local communities and authorities. From 1,650 km of Caribbean seashore, 181 beaches (730 km), are visited by one or all sea turtle species to nest or feed in surrounding grounds. Species distribution varied along the different regions of the Colombian Caribbean; however, there was a tendency of some species for specific ecosystems. Green turtles (Chelonia mydas) were most often found in the central Guajira, where sea grasses are most abundant, and hawksbills (E retmochelys imbricata) were most abundant on the coral reefs areas around San Bernardo, Rosario,...

Plan de acción nacional para la conservación de condrictios en las pesquerías uruguayas. (PAN - Condrictios Uruguay)
Provedor de dados: 20
Autores: Domingo, A.; Forselledo, R.; Miller, P.; Passadore, C.
Durante las últimas décadas se ha observado un incremento de la captura (descartada y retenida) de condrictios en las pesquerías artesanales e industriales, conjuntamente con un rápido crecimiento de las pesquerías no reguladas, lo cual ha ocasionado una disminución en muchas poblaciones de este grupo de peces en todos los mares del mundo. La sobrepesca y los elevados niveles de mortalidad ocasionados por la captura incidental, asi como la degradación y contaminación de áreas costeras donde se ubican las zonas de alimentación, reproducción y cría para muchas especies de condrictios, han colocado a este grupo de peces en una situación difícil. Estos hechos, combinados con el bajo potencial reproductivo y la estrategia de vida de la mayoría de las especies...

Incentives affecting biodiversity conservation and sustainable use: the case of land use options in Namibia
Provedor de dados: 20
Autores: Ashley, C.
Namibia is the most arid country south of the Sahara, with an economy fundamentally reliant on natural resources. The most scarce resource is water, and the main economic sectors are mining, fishing, agriculture, and wildlife-based tourism. The majority of the population live in rural areas, dependent on a wide range of natural resources. Sustainable use and conservation of biodiversity are therefore essential for the future. The question is how to achieve it? One key strategy is to assess -- and where necessary redesign -- economic incentives affecting use of natural resources. This paper illustrates the role of economic incentives in influencing the use of land-based renewable natural resources (RNR). It identify incentives which are being, or need to...

Autores: Kalil Filho, Antonio Nascim; Sousa, Valderês Aparecida de; Marzollo, Luiz Gustavo; Hirano, Elcio.
Imbuya (Ocotea porosa Nees et Martius ex. Nees, Lauraceae) is a species menaced of extinction. In 2003, Embrapa Florestas began a program for its conservation exsitu collecting germplasm at Colombo, Bocaiuva – Paraná state, Canoinhas and Caçador – Santa Catarina state, Brazil. Seeds were immersed in sulphuric acid 70% against dormancy of tegument. Low germination index were obtained, varying from 9,70% to 18,19% (june-october, 2003) due to the sulphuric acid. Inversely, seeds from Bocaiuva and Caçador not submitted to the treatment with sulphuric acid presented germination of 47% and 71%, respectively for these localities. Germination along this period increased from the 6th to the 7th month after sown. Beginning of germination occurred until 200 days...

Provedor de dados: 84
Autores: Faria,Luciene; Carrara,Lucas A.; Garcia,Frederico I.; Rodrigues,Marcos.
Chestnut-Capped Foliage-Gleaner (Hylocryptus rectirostris) is a Neotropical ovenbird species (Furnariidae) endemic to gallery forests of the Cerrado region of central Brazil. While it is not considered globally threatened, the degree of habitat loss occurring throughout much of its known distribution may warrant its inclusion on red lists beyond just the state of Sao Paulo. The primary objective of this study is to evaluate the conservation status of Chestnut-Capped Foliage-Gleaner according to those criteria adopted by the IUCN. Results of censuses conducted in the Serra do Cipó National Park were used to estimate the entire population size of the Chestnut-Capped Foliage-Gleaner and refine our understanding of its actual geographic distribution.

Abstract. The amphibian fauna of the state of Rio de Janeiro, in southeatern Brazil, is characterized by high species richness and rates of endemism, and is still insufficiently known. A first list of amphibian species with occurrence in the state was published in 2004 and reported 166 taxa, but since then many new records, descriptions of new taxa, and revalidations and synonymizations of species have consistently improved the knowledge about the state’s amphibian biodiversity. Thus, a review and update of that list was deemed necessary. We herein present an updated and commented list of amphibian species occurring in the state of Rio de Janeiro based on a survey of the literature. We recorded the occurrence of a total of 201 species of amphibians (197...

Habitat structure and their influence in lizard’s presence
Provedor de dados: 84
Autores: Cosendey,Beatriz Nunes; Rocha,Carlos Frederico Duarte da; Menezes,Vanderlaine Amaral de.
Abstract Many species are declining due to environmental and physical changes in their habitats. Such disturbs alter the availability of micro-habitats and influences the presence of lizards, being even worse for threatened and endemic species. Glaucomastix littoralis is a teiid species restricted to four restingas areas of Brazil. The understanding about the use and preferences of micro-habitats by the species and the consequents effects of substrate loss is important to prevent local extinctions. This study took place in restingas of Maricá, Jurubatiba and Grussaí, in Rio de Janeiro State. We sampled the vegetation of all areas, to access differences between the physical structures, and recorded the individuals sighted and the micro-habitat they were in,...

Abstract Forest fragments in urban areas have many habitat resources that frogs use for refuge, reproduction and growth. Knowledge of an anuran assembly is the first step towards understanding the importance of these forest fragments in areas highly threatened by anthropogenic actions. We sampled anurans during the day and night from November 2012 to August 2013 through visual and acoustic surveys. We found 333 individuals belonging to 19 species. The highest richness and abundance were recorded in January whereas the lowest richness and abundance were recorded in June. Most species were found in open areas. Our results highlight the importance of well-studied urban fragments for the anuran community. The conservation of these habitats may ensure the...

Why biogeographical hypotheses need a well supported phylogenetic framework: a conceptual evaluation
Provedor de dados: 84
Autores: Santos,Charles Morphy D.; Amorim,Dalton S.
A growing number of biogeographical methods have attempted to describe formal means of reconstructing the biogeographical history of the organisms. Whatever the biogeographical method, however, the source of systematic information has to be well worked out. Taxonomic noise is sometimes a true impediment to properly deal with the complexity of life in its three-dimensional aspects, the threefold parallelism represented by form, space and time. This paper argues that historical systematics is a necessary basis for a historical biogeography. Organismal phylogenies or at least hypotheses of monophyly should be taken as the basis for the study of distribution patterns. Whenever a non-monophyletic taxon is misleadingly taken as monophyletic, erroneous...

First survey of the ants (Hymenoptera, Formicidae) of Piauí: filling a major knowledge gap about ant diversity in Brazil
Provedor de dados: 84
Autores: Jory,Tainara Thais; Feitosa,Rodrigo Machado.
Abstract Piauí, a Brazilian Northeast state, has been considered one of the most important regions for the presence of new taxa in ants globally, especially considering the ecosystems’ diversity formed by the transition of the three biomes in the state, the Cerrado, Caatinga and the Atlantic Forest. Despite the recent increase in studies of ant diversity in the Neotropical region, Piauí still represents a major knowledge gap regarding its ant fauna. Therefore, this study aimed to increase the knowledge about the ant fauna of the state by generating a list of species with data obtained from the literature, online repositories and collection expeditions to the Serra da Capivara and Serra das Confusões National Parks. A total of 152 species in 52 genera and...

This work was carried out with the main objective of sampling the herpetofauna of a Cerrado site in the state of Piauí, Brazil, that is influenced by neighboring biomes and one of the least known regions of the domain. The herpetofauna of the different habitats present at Estação Ecológica de Uruçuí-Una (EEUU) was sampled intensively during three campaigns (two during the wet season and one during the dry season). We recorded 90 species, 64 reptiles and 26 anurans, a high local richness when compared to other well-sampled localities of the Cerrado. The rarefaction curve for both anurans and lizards shows that the observed richness is close to real and the richness estimators indicate that undetected species should be added with higher sampling effort....

Patterns of geographic distribution and conservation of the open-habitat avifauna of southeastern Brazilian mountaintops (campos rupestres and campos de altitude)
Provedor de dados: 84
Autores: Vasconcelos,Marcelo Ferreira de; Rodrigues,Marcos.
Montane open-habitats of southeastern Brazil are represented by the campos rupestres (principally in the Espinhaço Range) and by the campos de altitude (in the Serra do Mar and Serra da Mantiqueira). In spite of the occurrence of endemic species in both vegetation types, an analysis and synthesis of their bird communities have never been conducted. In this paper, we present an avifaunal survey of these areas, describe patterns of geographic distribution, and comment on the conservation of those open-habitats and their avifauna. A total of 231 bird species was recorded in the open-habitats of southeastern Brazilian mountaintops. In the campos rupestres, 205 species were recorded, while in the campos de altitude, the total was 123 species. Five patterns of...

Autores: Campos,Tatiana de; Cunha,Marcia Oliveira da; Sousa,Adna Cristina Barbosa de; Teixeira,Renata Beltrão; Raposo,Andrea; Sebbenn,Alexandre Magno; Wadt,Lucia Helena de Oliveira.
The objective of this work was to estimate the mating system parameters of a andiroba (Carapa guianensis) population using microsatellite markers and the mixed and correlated mating models. Twelve open‑pollinated progeny arrays of 15 individuals were sampled in an area with C. guianensis estimated density of 25.7 trees per hectare. Overall, the species has a mixed reproductive system, with a predominance of outcrossing. The multilocus outcrossing rate (t m = 0.862) was significantly lower than the unity, indicating that self‑pollination occurred. The rate of biparental inbreeding was substantial (t m ‑ t s = 0.134) and significantly different from zero. The correlation of selfing within progenies was high (r s = 0.635), indicating variation in the...

Conservation of 'Pedro Sato' guavas under treatment with 1-methylcyclopropene
Provedor de dados: 86
Autores: Bassetto,Eliane; Jacomino,Angelo Pedro; Pinheiro,Ana Luiza.
The search for techniques that extend shelf life of guava (Psidium guajava) fruits, and reduce its postharvest losses is desirable. The objective of this work was to evaluate the effects of concentrations of competitive ethylene antagonist 1-methylcyclopropene (1-MCP) on conservation of 'Pedro Sato' guava fruits. Treatments consisted of 0, 100, 300 or 900 nL L-1 of 1-MCP for 3 hours followed by storage at 25ºC, and 10ºC with 90±5% RH. The application of 900 nL L-1 1-MCP for 3 hours was efficient in delaying loss of skin color, and in keeping fruit firmness at both storage temperatures. The 300 nL L-1 of 1-MCP concentration was efficient in delaying skin color loss only when fruits were stored at 10ºC. The effect of 1-MCP was quite significant on the...

Autores: Scocchi,AM; Mroginski,LA.
Studies on in vitro storage of Melia azedarach -"paradise tree"- under slow-growth conditions were carried out to develop an efficient protocol for the conservation of the genetic diversity of the crop. The response to different growth retardation treatments was examined using clone E. In vitro cultures of apical meristem-tips (0.2-0.3 mm in length) could be effectively maintained for 12 months at 4ºC on ¼ MS basal medium supplemented with 0.5 µM BA. Shoot proliferation was observed on 67 % of the recovered apical meristem-tips, after 12 months at 4ºC. Rooting of the regenerated shoots was achieved by reculturing them on MS + 17.5 µM IBA, during 4 days and subsequently transferred to MS medium lacking growth-regulators for 30 days.

Demand-Side Factors in Optimal Land Conservation Choice
Provedor de dados: 31
Autores: Ando,   Amy Whritenour; Shah,   Payal.
The dominant paradigm of conservation-reserve planning in economics is to optimize the provision of physical conservation benefits (measured in units like species protected) given a budget constraint. Large-scale biology-based priority setting implies that the value we place on biodiversity and ecosystem function is not affected by human proximity to that natural capital. There is significant evidence, however, that human willingness to pay (WTP) for conservation declines with distance (e.g. Loomis 2000) – a phenomenon we refer to as “spatial value decay”. This paper begins a new strand of the conservation planning literature that takes demand-side factors – the location of people in the landscape and the degree to which their willingness to pay for an...

A note on the performance measure of conservation auctions
Provedor de dados: 31
Autores: Latacz-Lohmann,   Uwe; Schilizzi,   Steven.
We argue that previous assessments of discriminatory-price conservation auctions may have systematically overestimated their performance relative to uniform-payment schemes due to an inappropriate counterfactual comparison. We demonstrate that the cost curve (and not the bid curve) is the relevant supply curve when a uniform payment is offered and provide a theoretically rigorous counterfactual based on that insight. We estimate that the performance of BushTender may have been overrated by more than 50%.

Economic Comparison of Commodity and Conservation Program Benefits: An Example from the Mississippi Delta
Provedor de dados: 31
Autores: Anderson,   John D.; Parkhurst,   Gregory M.
Changes to commodity programs in the 2002 Farm Bill increased the value of crop base acreages on which decoupled payments are received.  The bill also expanded the availability of key conservation programs.  This paper compares the value of payments from commodity programs (along with continued crop production) to the easement payment (and recreational lease revenue) available under the Wetland Reserve Program.  A net present value model using risk-adjusted returns is employed in the analysis for Mississippi delta cropland containing rice, cotton, and soybean base.  Sensitivity analysis is conducted on some of the key variables affecting the decision.

Supply-side Policies to Conserve Biodiversity and Save the Orangutan from Oil Palm Expansion: An Economic Assessment
Provedor de dados: 31
Autores: Tisdell,   Clement A.; Swarna Nantha,   Hemanath.
Tropical forests are biodiversity-rich but are dwindling at a rapid rate, not only in Southeast Asia but elsewhere also. The result is a loss of natural ecosystems, a reduction in carbon sequestration, and increasing global extinction of wild species, including iconic species. While several developments contribute to the destruction of tropical forests, the main threat comes from their clearing for the purpose of agricultural production, for example in the Amazon Basin for the expansion of the beef industry and soya bean cultivation. In Borneo and Sumatra, the principal threat to tropical forests comes from the expansion of oil palm (Elaeis guineensis) cultivation. This is expected to result in significant biodiversity loss and is a danger to the...

How can we evaluate conservation auctions? Three Possible methods
Provedor de dados: 31
Autores: Schilizzi,   Steven.
By design, tenders are used when costs are unknown. But if costs are unknown, how can we evaluate the tenders, when their evaluation involves measuring their cost-effectiveness? We identify three approaches: theoretical, empirical and experimental. We first use experimental data to compare the efficiency of each approach, then apply the most efficient one to field data from the Scottish fishing vessel decommissioning program. We estimate the potential errors one would make in using a less efficient approach. In this case, we demonstrate a novel use of controlled lab experiments for interpreting field data and evaluating policy effectiveness.

FARMER EDUCATION AND ADOPTION OF SLASH AND BURN AGRICULTURE
Provedor de dados: 31
Autores: Schuck,   Eric C.; Nganje,   William E.; Yantio,   Debazou; Aquach,   Emmanuel.
Education can play a critical role in moving farmers in developing countries away from environmentally harmful slash and burn agriculture.  The present research examines the extent to which extension education can promote adoption of cropping systems other than slash and burn.  Choice of cropping system by farmers in Cameroon, whether slash and burn, multiple crops, or mono-cropping, is modeled as a function of farm size, farmer educational level, and visits by extension personnel.  Results indicate that higher visitation rates by extension personnel reduce not only the likelihood of farmers choosing slash and burn agriculture, but also promotes movement into mono-cropping.  Since mono-cropping represents a move toward export-oriented agriculture in...

CONSERVATION OF ENDANGERED SPECIES: CAN INCENTIVES WORK FOR PRIVATE LANDOWNERS?
Provedor de dados: 31
Autores: Langpap,   Christian.
It has been argued that the traditional regulatory approach of the Endangered Species Act, based on land-use restrictions, has failed to protect endangered species on private land. In response, there has been a call for the use of incentives to complement this regulatory approach. This paper examines the potential of incentives programs to elicit conservation-oriented management choices from landowners. Data obtained from a survey of non-industrial private forest owners in Oregon and Washington is used to examine the effectiveness of various incentives. The results indicate that incentives, in particular compensation and assurances, can be effective in increasing the conservation effort provided by landowners. The results also suggest that conservation...

Measuring the Cost-effectiveness of Conservation Auctions Relative to Alternate Policy Mechanisms
Provedor de dados: 31
Autores: White,   Benedict; Burton,   Michael P.
The principle motivation for using price-discriminating conservation auctions is that they are expected to be significantly more cost-effective than fixed-price mechanisms.  This paper measures cost effectiveness for tenders from two rounds of the Auction for Landscape Recovery in Western Australia relative to counterfactual fixed-price mechanisms.  If we assume that the bid equals the compliance cost, the auction gives a significant cost saving over fixed-price mechanisms.  If instead we assume that bids include an element of rent, fixed-price mechanisms can be more cost effective than the auction.  The significance of these results is that a fixed price scheme may achieve a similar level of cost effectiveness to a conservation auction, when one or more...

Green Giving: An Analysis of Contributions to Major U.S. Environmental Groups
Provedor de dados: 31
Autores: Richer,   Jerrell.
Data are compiled from the tax records of 29 major environmental organizations for the period 1980-1994 to identify factors that influence voluntary contributions. I examine the effects of organizational characteristics, such as fundraising expenditures and alternative sources of revenue, along with the impact of general economic conditions and the political climate. I find that government grants to the organizations had a positive and statistically significant impact on voluntary contributions rather than a crowding out effect. Contributions were price inelastic, where the price is defined as the effective cost to the donor of achieving a one-dollar increase in the provision of program services. Resources devoted to fundraising had a strong and positive...

Knowledge of Birds and Willingness to Pay for their Conservation: An Australian Case Study
Provedor de dados: 31
Autores: Wilson,   Clevo; Tisdell,   Clement A.
This case study concentrates on the extent of knowledge of members of the Australian public of Australia’s tropical bird species and their willingness to pay for their conservation.  In order to place this issue in context, it first provides background information on the status of Australian bird species, focusing attention on species that occur in tropical Australia.  Then, using survey results, this study considers the hypothesis that the public’s relative support for the conservation of different bird species depends on its comparative knowledge of their existence and status.  Based on experimental results from a sample of residents of Brisbane, Queensland (Australia), it is found that their knowledge of bird species that occur exclusively in the...

Of Experts, Politicians and Beasts: Setting Priorities in Farm Animal Conservation Choices
Provedor de dados: 31
Autores: Fadlaoui,   Aziz; Roosen,   Jutta; Baret,   Philippe V.
We consider the choice of farm animal breeds for conservation programmes. Based on an analysis of past decisions in EU member countries to enter breeds into the conservation programmes of rural development plans and based on the results of an expert survey among breed societies and scientists, we find an inconsistency in the valuation of breed characteristics. Policy makers seem to be less concerned about considering true extinction risk and diversity and more about cultural values and about means to benefit a larger number of farmers for raising rare breeds.

Evaluating conservation auctions with limited information: the policy maker’s predicament
Provedor de dados: 31
Autores: Schilizzi,   Steven; Latacz-Lohmann,   Uwe.
Buying environmental services from private landholders using tendering mechanisms are usually subject to a budget constraint. Auction theory has mostly focused on target-constrained auctions and is less well developed for this type of auction. This paper examines a theoretical model specifically developed for budget-constrained tenders and assesses its capacity to predict tendering performance under information limitations typical of those found in field applications. But this assessment cannot be done without complementing the model with controlled laboratory experiments. Subject to their external validity, we find that the model is able to make the correct policy recommendation when comparing the tender to an equivalent fixed price scheme, even when the...

Input Use and Conservation Investments among Farm Households in Rwanda: Patterns and Determinants
Provedor de dados: 31
Autores: Clay,   Daniel C.; Kelly,   Valerie A.; Mpyisi,   Edson; Reardon,   Thomas.
One of the Government of Rwanda’s key post-war policy objectives has been to increase agricultural productivity and ensure food security by promoting a transition from semi-subsistence production and marketing practices to intensive production and highly commercialized agricultural markets. The government wants farmers to increase land and labor productivity through the use of modern inputs, thereby generating substantial surpluses which can be sold to pay for inputs and generate increases in farm incomes.

ASSESSING CHANGES IN SOIL EROSION RATES: A MARKOV CHAIN ANALYSIS
Provedor de dados: 31
Autores: Skaggs,   Rhonda K.; Ghosh,   Soumen.
Markov chain analysis (one-step and long-run) is applied to the National Resources Inventory (NRI) database to evaluate changes in wind-based soil erosion rates over time.  The research compares changes in soil erosion rates between NRI sample sites with and without applied conservation practices for a random sample of Great Plains counties.  No significant differences between sites are found for half of the counties evaluated.  The effectiveness and efficiency of conservation policies are thus questioned in light of these research results.

The Rio Grande has headwaters in Colorado, flows through New Mexico, and serves as the United States.–Mexico border in Texas, emptying into the Gulf of Mexico. Snow melt in Colorado and northern New Mexico constitutes the water river supply for New Mexico and the El Paso region, whereas summer monsoonal flow from the Rio Conchos in Mexico and tributaries, including the Pecos River, provides the Rio Grande flow for southern Texas. The region is mostly semiarid with frequent long-term drought periods but is also characterized by a substantial irrigated agriculture sector and a rapidly growing population. International treaties and interstate compacts provide the rules for allocation of Rio Grande waters between the United States and Mexico and among...

Household Level Financial Incentives to Adoption of Conservation Agricultural Technologies in Africa
Provedor de dados: 31
Autores: Haggblade,   Steven; Tembo,   Gelson; Donovan,   Cynthia.
Although several studies have been conducted to determine the viability of conservation agriculture in Sub-Saharan Africa, almost all such studies are fragmented – often country specific – and with undue emphasis on output effects. However, assessment of the attractiveness of these technologies in Sub-Saharan Africa requires a detailed case-by-case comparison of changes in output and input costs and benefits. This paper reviews a set of responses known collectively as “conservation” or “sustainable” agriculture. Though definitions vary, these technologies typically involve agricultural management practices that prevent degradation of soil and water resources and thereby permit sustainable farm productivity without environmental degradation.

SOME IMPACTS OF ARIZONA DEPARTMENT OF ENVIRONMENTAL QUALITY (ADEQ) ENFORCEMENT IN THE DAIRY INDUSTRY IN MARICOPA COUNTY, ARIZONA
Provedor de dados: 31
Autores: Hemmer,   Ronald.
Although water quality is a valid purpose for watershed projects under the PL83-566 Watershed Protection and Flood Prevention Act, historically very few water quality projects have ever been implemented in Arizona.  This is largely due to the difficulty in measuring "non-controversial" monetary benefits associated with positive water quality impacts and to policy biased in favor of those projects with a higher monetary benefit-cost ratio.  These reasons, among others, has prompted NRCS field economists to seek alternate methods to measure project benefits and costs. While the direct measurement of water quality benefits would be the preferable method to use, IMPLAN, through regional economic impact analysis, provides a way of measuring another category of...

Demographic and Management Factors Affecting the Perceived Benefit of Winter Cover Crops in the Southeast
Provedor de dados: 31
Autores: Bergtold,   Jason S.; Duffy,   Patricia A.; Hite,   Diane; Raper,   Randy L.
The inclusion of cover crops in cropping systems brings both direct and indirect costs and benefits. Farmers will adopt and continue to utilize cover crops in their production systems as long as the perceived benefit of using cover crops (e.g. increased yield, higher profits, and improved soil productivity) is positive.  The perceived benefits, while partially based on actual changes, may be influenced by demographic, economic and management factors. The purpose of this paper is to examine the demographic and management factors affecting the perceived benefit, in terms of improved crop yield, of using winter annual cover crops. A tobit model is estimated using survey data of Alabama farmers examining cover crop use and management. The model examines the...

This paper provides an overview of concepts of sustainable agriculture and possible methods of attaining sustainability of agricultural yields and production. Reasons are given as to why modern industrialised agriculture might be less sustainable in terms of yields than traditional agriculture. The question of whether organic agriculture is likely to be more sustainable than non-organic agriculture is considered as well as organic agriculture’s likely impact on wild biodiversity. The impact of the development of agriculture on wild biodiversity is assessed because some environmentalists see the conservation of wild biodiversity as an important ingredient of sustainable development. However, there is a policy conflict between conservationist groups. Some...

The Cost-Effectiveness of Conservation Payments
Provedor de dados: 31
Autores: Ferraro,   Paul J.; Simpson,   R. David.
Intact ecosystems provide important global services. Many valuable ecosystems are located in low-income countries in which citizens are not in a position to provide global public goods gratis. To address this problem, international conservation and development donors have been making substantial investments in habitat conservation. Among the more common conservation schemes are interventions aimed at encouraging commercial activities that produce ecosystem services as joint products. We argue that it would be more cost-effective to pay for conservation performance directly. We use a simple yet general model to establish three conclusions. First, the overall cost of conservation is least when direct payments are employed. Second, the donor will generally...

Impact of Natural Resource Conservation Policies on Household Consumption Around Zambian National Parks

Autores: Tembo,   Gelson; Bandyopadhyay,   Sushenjit; Pavy,   Jean-Michel.
Key Policy Points - Game Management Areas (GMAs) in Zambia aim to combine nature conservation with economic empowerment of rural households and communities. - We find evidence of consumption gains from living in GMAs and from participating in natural resource management through Community-Resource Boards (CRBs) and Village Action Groups (VAGs). - However, these benefits are unevenly distributed. Only GMAs with limited alternative livelihoods (Bangweulu and South Luangwa) exhibit significant consumption benefits. Also, the benefits accrue mainly to the relatively well off while the poor do not gain even if they participate. - Resources from ZAWA to CRBs seldom reach the VAGs. Richer, more educated community members participate at CRB or higher level while...

The Precautionary Principle Revisited: Its Interpretations and their Conservation Consequences
Provedor de dados: 31
Autores: Tisdell,   Clement A.
The precautionary principle was included in 1992 in the Rio Declaration on Environmental and Development and is a part of important international agreements and documents, for example, the Convention on Biological Diversity. Yet the interpretation of this principle is not straightforward as a guide for environmental policy – a variety of interpretations are possible. This paper identifies and examines various economic versions of the principle. Furthermore, it shows that different economic versions of the principle can give rise to conflicting policy recommendations for resource conservation. In addition, it demonstrates that applications of the principle do not always favour (natural) resource conservation (for example, biodiversity conservation) although...

USDA defines beginning farmers and ranchers as those who have operated a farm or ranch for 10 years or less either as a sole operator or with others who have operated a farm or ranch for 10 years or less. Beginning farmers tend to be younger than established farmers and to operate smaller farms or ranches, some of which may provide no annual production. Beginning farmers often face obstacles getting started, including high startup costs and limited availability of land. USDA—through the Farm Service Agency and the Natural Resources Conservation Service—provides loans and conservation assistance to beginning farmers and ranchers. This report draws on data from annual surveys and the Census of Agriculture to provide policymakers with a better understanding...

IMPACTS OF INCORPORATING LAND EXCHANGES BETWEEN FORESTRY AND AGRICULTURE IN SECTOR MODELS
Provedor de dados: 31
Autores: Alig,   Ralph J.; Adams,   Darius M.; McCarl,   Bruce A.
The forest and agriculture sectors are linked by having a portion of their land bases suitable for use in either sector.  A substantial part of the southern land base is suitable for either forestry or agriculture use, with most of forestation on U.S. agriculture land in the South.  We examine how land exchanges between forestry and agriculture are influenced by specific federal conservation and farm support policies, including changes in the Conservation Reserve Program.  Reallocation of land is a significant part of the sectors' responses to the policies, along with intensification of timber management on existing southern forests.

This paper discusses land occupation and natural resources utilization, and analyses the forest conservation paradox (desire/barriers) experienced by small farmers of Alto Moju region, in the Amazon. This paradox is marked by a lack of land tenure regularization, the role of timber as a tradable asset saved for hard times, and low level of organization amongst local families. To proceed with the analysis, the authors used qualitative research methods (semi-directive interviews and participant observation), which favored the farmers’ representations regarding the use of natural resources and the social reproduction of families. From examining the land occupation history and the zoning with key actors, the authors conclude that the social reproduction of...

Farmers' Rights and Protection of Traditional Agricultural Knowledge
Provedor de dados: 31
Autores: Brush,   Stephen B.
Although achieving in situ conservation is possible without changing farmers’ customary management of crops as common pool resources, an alternative approach is to negotiate a bioprospecting contract with providers of the resource that involves direct payment and royalties. This bioprospecting mechanism implies a change in the customary treatment of crop genetic resources as common pool goods and is in line with national ownership mandated by the Convention on Biological Diversity (CBD). This paper questions the value of bioprospecting for protecting traditional agricultural knowledge and argues for a common pool approach. It examines the nature of crop genetic resources and farmers’ knowledge about them, and it analyzes the nature of the ‘common heritage’...

The Orangutan-oil Palm Conflict: Economic Constraints and Opportunities for Conservation
Provedor de dados: 31
Autores: Swarna Nantha,   Hemanath; Tisdell,   Clement A.
The future of the orangutan (Pongo spp.) is far from secure despite the species’ high profile and media attention. The traditional threat to the orangutan has been widespread logging, but the continuing conversion of remaining habitat for oil palm (Elaeis guineensis) cultivation is hastening its extinction in the wild. This situation is driven by a robust global market for palm oil as a vegetable oil and biofuel. In tackling this conservation problem, therefore, economic factors cannot be overlooked. This article analyses these factors and how they curtail effective orangutan conservation. Of significance are the high opportunity costs of orangutan conservation and market failures associated with the public-goods nature of the orangutan’s forest habitat....

The production of biofuels has been supported by many conservationists and environmentalists on the grounds that it reduces greenhouse gas emissions and is a renewable energy substitute for non-renewable fossil fuels, mainly oil. More recently the domestic production of biofuels (and the domestic supply of other forms of alternative energy) have been welcomed by several nations as ways to reduce their oil imports and increase their energy self-sufficiency, as for example, has happened in the United States. India also which is very dependent on oil imports has also begun to produce biofuels in Kerala and elsewhere. However, doubts have been raised about the effectiveness of biofuel use as a means to reduce the accumulation of greenhouse gases and elementary...

Monitoring of compliance in Australian conservation contracts
Provedor de dados: 31
Autores: Crowe,   Bronwyn; White,   Benedict; Pannell,   David J.; Lindner,   Robert K.
Government and non-government conservation agencies have long-term goals and objectives to provide environmental services, such as conserving the biodiversity of Australian native vegetation. In addition to national parks and reserves, private lands are often included in conservation programs to achieve these objectives. Formal contracts are entered into between the private landholder and the conservation agency to provide environmental services, or more commonly to provide inputs that are likely to lead to environmental services. The paper examines the costs and benefits of monitoring these conservation contracts when biodiversity change is stochastic.

Conservation of the Proboscis Monkey and the Orangutan in Borneo: Comparative Issues and Economic Considerations
Provedor de dados: 31
Autores: Tisdell,   Clement A.; Swarna Nantha,   Hemanath.
Concentrating on their presence in Borneo, the ecology and conservation of two large Southeast Asian primates, the orangutan Pongo pymaeus and the proboscis monkey Nasalis larvatus are reviewed. The former species occurs only in Borneo and Sumatra and the latter only in Borneo. The comparative threats facing these two endangered primates and their approximate numbers in the wild are put into perspective. The long-term survival of both species is adversely affected by the degradation and conversion of their suitable forest habitat by logging and agriculture, the occurrence of hunting, poaching and forest fires. The effectiveness of measures to conserve these species are discussed and evaluated from the standpoint of economics. It is concluded that informed...

Conservation impediments and incentives – progressing the understanding of linkages between the adoption of conservation practices and the motivational orientation of graziers in the tropical savannas
Provedor de dados: 31
Autores: Gregg,   Daniel; Greiner,   Romy.
The adoption of conservation practices is a complex matter – rural landholders consider a wide variety of factors and characteristics when deciding whether to adopt a conservation practice. To confound the issue, recent research has suggested that the goals of landholders affect the adoption of conservation practices by creating a subjective consideration of the relative importance of impediments and effectiveness of incentives in the adoption decision. In this research we describe an empirical link between graziers’ goals and their perceptions of the relative importance of impediments and the effectiveness of incentives in the adoption of conservation practices. The research was carried out in the tropical savannas region of Australia where pastoral...

Wetlands and Agriculture: Private Interests and Public Benefits
Provedor de dados: 31
Autores: Heimlich,   Ralph E.; Wiebe,   Keith D.; Claassen,   Roger; Gadsby,   Dwight M.; House,   Robert M.
Society has recently increased the value it places on the services that wetlands provide, including water quality improvements, flood control, wildlife habitat, and recreation. However, owners of wetlands are often unable to profit from these services because the benefits created are freely enjoyed by many. This report examines differences between public and private incentives regarding wetlands. Federal wetland policy has shifted in recent decades--from encouraging wetland conversion to encouraging wetland protection and restoration--in an effort to balance public and private objectives. The report assesses the need for continued wetlands protection policies as the United States approaches achieving the goal of no net loss of wetlands.

Farmer Preferences for Milpa Diversity and Genetically Modified Maize in Mexico:  A Latent Class Approach
Provedor de dados: 31
Autores: Birol,   Ekin; Villalba,   Eric Rayn; Smale,   Melinda.
Maize, the second most globally important staple crop after wheat, originated in Mexico, where it is typically grown as part of a set of associated crops and practices called the milpa system. This ancient mode of production is practiced today in ways that vary by cultural context and agro-environment. Milpas generate private economic value, in terms of food security, diet quality and livelihoods, for the two-million farm households who manage them. Furthermore, milpas generate public economic value by conserving agrobiodiversity, especially that of maize landraces, which have the potential to contribute unique traits needed by plant breeders for future crop improvement. In this way, milpas contribute to global food security in maize. However, the...

Farmers' Willingness to Grow Cover Crops:  Examining the Economic Factors of Adoption in Alabama
Provedor de dados: 31
Autores: Bergtold,   Jason S.; Fewell,   Jason E.; Duffy,   Patricia A.
The inclusion of cover crops in cropping systems brings both direct and indirect costs and benefits. The literature has shown that cover crops can improve soil conservation and productivity, potentially improving cash crop yields and decreasing cash crop production costs. Farmers will adopt cover crops if the net economic benefit of utilizing them is positive. This study examines farmers’ willingness to grow cover crops as a soil conservation practice and to examine the socio-economic factors affecting their decision. Survey data collected in 2007-8 from Alabama farmers about cover crop adoption and management is utilized to estimate a cover crop adoption model.

Coordination and Strategic Behaviour in Landscape Auctions
Provedor de dados: 31
Autores: Valle,   Haydn; Capon,   Timothy; Harris,   Michael; Reeson,   Andrew.
Designing a conservation auction where bidders know the ecological value of their land poses challenges for policy makers because bidders will tend to increase their asking price. This is known as strategic behaviour, and it is particularly prevalent in sequential auction settings. The tender process ceases to be competitive when strategic behaviour occurs, eroding the efficiency advantages of an auction. To overcome this problem, contract options can be designed such that early winners are restricted in their efforts to strategically manipulate auction outcomes. Simply offering multi-period contracts could achieve this goal if participants need to wait for their contracts to expire before they can change their asking price. This idea was tested in a...

Wildlife-based Tourism and Increased Tourist Support for Nature Conservation Financially and Otherwise: Evidence from Sea Turtle Ecotourism at Mon Repos
Provedor de dados: 31
Autores: Tisdell,   Clement A.; Wilson,   Clevo.
Arguments of most conservationists supporting ecotourism have been based upon the views that it is environmentally friendly as a resource-use and that receipts from it can counter demands to use the natural resources involved for more extractive economic purposes.  But wildlife-based ecotourism can also have positive impacts in itself on the willingness of tourists to pay for wildlife conservation, strengthen the pro-conservation attitudes of tourists and foster personal actions by them which contribute to wildlife conservation.  These aspects are explored in this article on the basis of a survey of tourists visiting Mon Repos Beach near Bundaberg, Queensland for the purpose of watching marine turtles.  The results enable several of the conservation...

An Economic Evaluation of Conservation Farming Practices for the Central West of NSW
Provedor de dados: 31
Autores: Farrell,   Terence C.
Economic benefits that arise from conservation farming practices need to be assessed over several years to account for improvements in soil structure and nutrient levels. A gross margin model was used to assess benefits over the eight-year period 1999-2006 for 12 regions in the central west of NSW. The annual benefits from improved soil structure ranged from $2.46 to $12.82 per hectare (ha). A reduction in tractor power produced annual savings in the range of $0.60 to $4.05 per ha. The cost of soil compaction by livestock grazing on crop areas ranged from $3.41 to $14.90 per ha. The break-even time to pay back costs for the conversion of machinery for no-till seeding was two to three seasons.

An Analysis of the Effects of Uncertainty and Irreversibility on Farmer Participation in the Conservation Reserve Program
Provedor de dados: 31
Autores: Isik,   Murat; Yang,   Wanhong.
A real options model is developed to examine the determinants of farmer participation in the Conservation Reserve Program (CRP). This study contributes to the literature by developing a framework for ex post analysis of  uncertainty and irreversibility. It extends the applications of real options models to analyze farmer participation in the CRP. The model incorporates land and owner attributes, and determines whether uncertainty and irreversibility affect the probability of participation. Option values play a significant role in farmer decisions to retire land by reducing the probability of participation. These results have implications for the design and implementation of conservation programs.

Incentives for Residential Water Conservation: Water Price, Revenue, and Consumer Equity in Florida
Provedor de dados: 31
Autores: Rawls,   Colin; Borisova,   Tatiana; Berg,   Sanford; Burkhardt,   Jeffrey.
Economic theory suggests that price incentives can be used to encourage water conservation in residential consumers.  Conservation water rates are designed to send price signals that encourage households to reduce discretionary water use in the long term. However, it is not always clear that conservation rates effectively provide meaningful incentives. Utilities themselves may also not have strong incentives to implement conservation rates. If conservation rates have a negative impact on revenue, or if they lead to increased revenue variability, utilities may have a disincentive to use them.  In addition, block pricing structures (where unit water rate increases with water usage) may be inequitable, in the sense that the “revenue burden” is borne...

Autores: Boisvert,   Valerie.
Building on ongoing research, this paper aims at suggesting alternative ways to conventional IPR systems to promote local varieties and related knowledge in developing countries. Many attempts to protect genetic diversity and local knowledge through IPR are in jeopardy because of misunderstanding on the terms of the debate and misrepresentation of the claims and interests of the various stakeholders. The paper then suggests that to improve rural livelihood conditions and promote genetic diversity conservation, it would be more efficient and satisfactory for the parties involved to build on local perceptions of foodstuff production and associated knowledge. It is easier and more feasible to stress the importance of a given know-how in the processing of...

Predicting the performance of conservation tenders when information on bidders's costs is limited
Provedor de dados: 31
Autores: Schilizzi,   Steven; Latacz-Lohmann,   Uwe.
Buying environmental services from private landholders using tendering mechanisms are usually subject to a budget constraint. Auction theory has mostly focused on target-constrained auctions and is not well developed for this type of auction. This paper examines the predictive capacity of a simple model developed for budget-constrained tenders, already used to design new conservation programs, by submitting it to controlled lab experiments. We study the capacity of the model to predict both experimental bids and the performance of the auction institution, based on the kind of limited information typically available to a conservation agency. We conclude there exists an optimal level of information on bidders’ costs, neither too large nor to small, making...

Comparative Public Support for Conserving Reptile Species is High: Australian Evidence and its Implications
Provedor de dados: 31
Autores: Tisdell,   Clement A.; Wilson,   Clevo; Swarna Nantha,   Hemanath.
This paper investigates factors influencing the public’s support for conservation of tropical reptile species in a focal group drawing on Australian data and an experiment involving a sample of the Australian public. The influences of the likeability of the species, their degree of endangerment, ethical considerations as well as knowledge are examined and found to be important. Likeability is found to be much less important than the existing literature suggests. This is highlighted by comparing the likeability of the focal group of reptiles with that for a group of birds and a group of mammals with differences in willingness to pay for their conservation.

Frankincense from Boswellia papyrifera forest (BPF) is a traded non timber forest product (NTFP) used in pharmaceutical, food, cosmetic and chemical industries. However, the resource in northeastern Africa is under continuous degradation and requires conservation measures. Data from a discrete choice contingent valuation study are used to assess the factors influencing rural households’ willingness to pay (WTP) and willingness to contribute labor (WTCL) for BPF conservation in Ethiopia. The standard probit, bivariate probit and interval data models were used for modeling respondents’ WTP and WTCL. We found household income as the most important factor affecting WTP whereas number of household labor is the most important factor affecting WTCL. Mean lower...

The Role of Cost-Share Rates and Prices on the Size of Conservation Investments in EQIP
Provedor de dados: 31
Autores: Hand,   Michael S.; Nickerson,   Cynthia J.
Per-unit costs for conservation investments in the Environmental Quality Incentives Program (EQIP) are determined by market prices for conservation practices and payment cost-share rates. This study examines the relative importance of these factors in determining the size of the most common conservation investment in EQIP. Results suggest that per unit costs have a significant but inelastic impact on the size of conservation investment; as expected, higher per-unit costs are associated with smaller investments. This effect is largely due to variation in market prices of conservation practices for the majority of farmers. However, cost-share rates may play a role for some limited resource farmers.

Intrafirm Effects on Water Conservation in Agriculture
Provedor de dados: 31
Autores: Moreno,   Georgina.
Conservation technology adoption behavior is frequently analyzed at the smallest unit of production to capture important heterogeneity among adopters. Conclusions about firm-level decisions are drawn from these microunit outcomes.  However, there may be significant intrafirm interactions that create a dependence among the microunits.  This paper tests and quantifies these effects. Using a unique dataset of agricultural water use in California, this paper finds significant differences in water price elasticities of conservation technology adoption between the standard model and models that accounts for the intrafirm interactions.

Lamington National Park in Queensland, Australia is noted for its rainforest and is part of the World Heritage listed property but prior to this work, no systematic study has been done of the importance of birds to its visitors.  This study is based on data from survey forms handed to visitors at an important site in the park and completed by visitors following their visit.  It yielded 622 useable responses.  These enabled us to establish the comparative importance of birds as an attraction to this site for this sample of visitors.  Furthermore, logit regression is used to target analysis and to identify factors that increase the likelihood of a visitor saying that birds are an important attraction.  In addition, the relative importance to visitors of...

What role does knowledge of wildlife play in providing support for species' conservation
Provedor de dados: 31
Autores: Wilson,   Clevo; Tisdell,   Clement A.
Conservation of biodiversity is a complex issue. Apart from the creation of nature reserves, there is a plethora of other factors that are part of this complex web.  One such factor is the public knowledge of species. Since public funding is imperative for the conservation of species and creation of reserves for them it is important to determine the public’s awareness of species and their knowledge about them. In the absence of such awareness and knowledge, it is possible that the public may misallocate their support. In other words, resources may be provided for species that do not need support urgently.  We show how availability of balanced information about species helps the public to make rational decisions and to allocate support (e.g. monetary) to...

Tax Rules, Land Development, and Open Space
Provedor de dados: 31
Autores: Simpson,   R. David.
Concern about "open space" is growing. Conservation advocates worry that private land use decision-makers preserve too little open space. Yet private land developers are deciding on their own to preserve open space in new developments because it provides amenities to purchasers of lots. Moreover, tax provisions provide incentives for preserving more open space than would be privately optimal. Many jurisdictions have adopted "use-value assessment" standards granting favorable tax treatment to lands maintained in open space. Also, donations of open space can be deducted from income in computing tax liabilities. Both factors may be empirically important, although tax deductibility may have larger conservation effects than does use-value assessment. These...

This paper discusses regulation of rural land-use and compensation, both of which appear to have become more common but also more disputed. The implications of contemporary theories in relation to this matter are examined. Coverage includes the applicability of new welfare economics, the relevance of the neoclassical theory of politics, and the implications of contemporary theories of social conflict resolution and communication. Examining case studies of Swiss and Australian regulation of the use of rural properties and the ensuing conflicts, it is found that many decisions reflect a mixture of these elements. Rarely, if ever, are social decisions in this area made solely on the basis of welfare economics, for instance social cost-benefit analysis. Only...

Points out that sustainability as such does not provide a clearcut guide to policy. First one has to decide what is to be sustained. If this is agreed, it must be in an operational from. However, difficulties may still emerge since opinions may differ about how to achieve. This is illustrated by differences in the views of economists about how sustainable development is to be achieved. Orthodox economists stress the importance of the accumulation of man-made capital to achieve this end whereas neo-Malthusians stress the importance of conserving natural resource and environmental capital. Both take an anthropocentric point of view. For political reasons the neo-Malthusian has had little support but it may eventually turn out to be correct. Economics is...

Exactly how would farm commodity and conservation payments be combined? What difference would it make for environmental gain and farm income support? This report approaches the questions in two ways. First, spending patterns in existing commodity and conservation programs are analyzed to determine the extent to which producers who are currently receiving commodity payments also receive conservation payments.

The paper examines the joint adoption of conservation tillage, crop rotations, and soil testing by small and limited-resource farmers in the Southeast. The objectives are to determine the potential eligibility of small farmers for the Conservation Security Program, examine socioeconomic factors affecting adoption, and assess the interdependence between adopting different conservation practices. Results indicate that conservation management, ethnicity, and farm characteristics affect practice adoption. Of the producers surveyed in the study, 7% meet Conservation Security Program eligibility requirements, while the other 93% have less than a 20% likelihood of adopting the needed practices to qualify.

Monitoring of Compliance in Western Australian Conservation Contracts
Provedor de dados: 31
Autores: Crowe,   Bronwyn; White,   Benedict; Pannell,   David J.
Contracting with private landholders for labor towards production of environmental services (payment for actions) or the environmental services themselves (payment for outcomes) is reliant on the environmental organization’s ability to monitor and assess the environmental outcomes provided. Inaccurate and costly assessment reduces the cost effectiveness of the contract. Different assessment technologies will have different impacts on the cost effectiveness and optimal contracting choice of the environmental organization. The paper compares the influence of field assessment by a local expert, and remote assessment via satellite imagery, on the optimal contracting decision for the Western Australian wheat belt.

Demographic and Management Factors Affecting the Adoption and Perceived Yield Benefit of Winter Cover Crops in the Southeast
Provedor de dados: 31
Autores: Bergtold,   Jason S.; Duffy,   Patricia A.; Hite,   Diane; Raper,   Randy L.
The inclusion of cover crops in cropping systems brings direct and indirect costs and benefits. Farmers will adopt and utilize cover crops as long as the perceived benefit of using them is positive. This paper examines the demographic and management factors affecting the adoption and perceived benefit (in terms of improved crop yield) of using winter annual cover crops. A double selectivity model of cover crop adoption and perceived yield gain was estimated using survey data of Alabama farmers examining cover crop use and management.  Results may help in understanding factors shaping farmers’ perceptions, adoption, and retention of cover crops.

Autores: Tisdell,   Clement A.; Wilson,   Clevo; Swarna Nantha,   Hemanath.
Five species of reptiles present in tropical Australia are considered in this study. These are the hawksbill turtle (Eretmochelys imbricata); the northern long-necked turtle (Chelodina rugosa); the taipan snake (Oxyuranus scutellatus); the freshwater crocodile (Crocodylus johnstoni); and the saltwater crocodile (Crocodylus porosus).  Background information is provided on the ecological status of each of these species and after outlining their human use (including commercial use) and management in Australia, an experimental survey method is introduced and results from its application are reported and analysed. The survey method involves two serial surveys of a sample of 204 Brisbane (Australia) residents. The first survey is based on the initial knowledge...

Integrating Stakeholder Input into Water Policy Development and Analysis
Provedor de dados: 31
Autores: Guerrero,   Bridget L.; Amosson,   Stephen H.; Almas,   Lal K.
Agricultural water use is becoming an issue in much of the South due to population growth. Results of projects evaluating the impacts of conservation strategies aimed at reallocating or extending the life of water supplies are being met with great skepticism by stakeholder groups. In order to gain acceptance of results, it is essential that stakeholder groups be involved from the beginning in the identification of potential water conservation strategies and be kept informed throughout the project. The objective of this paper is to review previous attempts at involving stakeholders and the methodology currently being employed in the Ogallala Aquifer Project.

Risk-Adjusted Comparison of Conservation Reserve Program Payments Versus Production Payments for a Corn-Soybean Farmer
Provedor de dados: 31
Autores: Ibendahl,   Gregory A.
Conservation reserve program (CRP) payments amount to several billion dollars annually.  Payments are allocated to both remove land from production and to help farmers pay for conservation improvements.  However, research examining whether farmers increase their utility with CRPs is limited.  This paper uses simulation analysis and certainty equivalents to compare farming income to payments under the CRP.  Farming income is a combination of crop production and government payments as specified in the 2002 Farm Bill.  This analysis focuses on farms in three different counties in Kentucky.  Results indicate that CRPs are good choices for many farmers.

Private Decisions and Public Goods: Trade-Offs in the Conservation Programs in the New Farm Bill: Discussion
Provedor de dados: 31
Autores: Davis,   Todd D.
The 2002 Farm Bill creates several opportunities for landowners to adopt management practices that protect and improve soil and water quality.  Landowners considering enrollment in conservation programs must compare the monetary and nonmonetary costs and benefits from removing land from production agriculture.  The overall purpose of this invited paper session was to improve the understanding of the factors affecting a landowner’s decision to enroll in conservation programs.  Papers addressed the environmental benefits of conservation programs and compared the returns to enrolling in conservation programs to the returns from production agriculture.

Tropical inselbergs: habitat types, adaptive strategies and diversity patterns
Provedor de dados: 88
Autores: Porembski,Stefan.
Inselbergs are isolated rock outcrops that rise abruptly above the surrounding plains. Granitic and gneissic inselbergs are geologically and geomorphologically old and occur throughout a broad spectrum of climatic zones. They form microclimatically and edaphically dry growth sites that support a highly specialized vegetation. Based on physiognomic criteria a number of habitat types can be distinguished that are widespread on inselbergs (e.g. ephemeral flush vegetation, monocotyledonous mats, rock pools). Three hot spots of global inselberg plant diversity can be identified which are both rich in species and endemics: a) southeastern Brazil, b) Madagascar and c) southwestern Australia.

Nós e as plantas: ontem e hoje
Provedor de dados: 88
Autores: SALATINO,ANTONIO.
Áreas verdes, ruas e praças arborizadas em locais urbanos são características que apenas recentemente adquiriram relevância no mundo ocidental. Parece que os habitantes antigos das cidades não valorizavam uma estreita proximidade com plantas. Neste artigo, sugere-se que isso é uma conseqüência de uma ruptura entre o homem e a natureza, que ocorreu na emergência da tradição judaico-cristã na história da civilização ocidental. A ausência de laços entre natureza e cristianismo é evidente na ausência de árvores, jardins e outros aspectos representativos da natureza em torno de templos cristãos. O cristianismo também representou o fim da mitologia, um processo que conduziu ao desenvolvimento do pensamento racional, favorecendo assim o desenvolvimento da...

(In vitro culture at low temperature and ex vitro acclimatization of Vriesea inflata an ornamental bromeliad). In vitro culture by seeds is a technique for preservation of threatened species because it may provide a large number of plants with genetic diversity. The bromeliad Vriesea inflata (Wawra) Wawra, an ornamental bromeliad, is extensively and illegally collected from the nature and must be preserved. It is possible to form plant threatened collections in vitro by reducing the temperature of culture, while occupying little space, with the consequent reduction of maintenance costs. This work evaluated the influence of temperature on in vitro growth and morphology of plants of V. inflata, with the aim of establishing a slow growth-rate and analyzing...

Abstract The Atlantic Forest of South America is one of the most degraded tropical forests and the cultivation of sugarcane is considered one of the main causes. In humid forests termites stand out with regard to their abundance and functional importance. The present study aimed to compare termite assemblages of fragments of the Atlantic Forest with that of the sugarcane matrices that surround them. Collections were performed in two sugarcane plantations in Northeast Brazil. In each plantation a fragment of Atlantic Forest and an adjacent sugarcane field were sampled using a standardized termite sampling protocol. A total of 39 species and 302 encounters were recorded. Species richness, relative abundance and composition differed significantly between...

Rediscovery of the putatively extinct ant species Simopelta minima (Brandão) (Hymenoptera, Formicidae), with a discussion on rarity and conservation status of ant species
Provedor de dados: 92
Autores: Brandão,Carlos Roberto Ferreira; Feitosa,Rodrigo Machado; Schmidt,Fernando Augusto; Solar,Ricardo Ribeiro de Castro.
Simopelta minima (Brandão, 1989) was originally described based on four workers collected in soil samples from a small cocoa plantation in Ilhéus, state of Bahia, northeastern Brazil. In the subsequent years after the description, this cocoa plantation was eliminated and the species was then considered extinct by the Brazilian environmental institutions. The recent rediscovery of S. minima workers in subterranean pitfall trap samples from Viçosa, state of Minas Gerais, southeastern Brazil, over 1.000 km distant from type locality, suggests that the rarity and vulnerability status of some ant species may be explained by insufficient sampling of adequate microhabitats, in time and space.

Effects of changes in the riparian forest on the butterfly community (Insecta: Lepidoptera) in Cerrado areas
Provedor de dados: 92
Autores: Cabette,Helena S.R.; Souza,Jaqueline R.; Shimano,Yulie; Juen,Leandro.
ABSTRACT Preserved riparian vegetation usually has greater environmental complexity than the riparian vegetation modified by human actions. These systems may have a greater availability and diversity of food resources for the species. Our objective was to evaluate the effect of changes on the structure of the riparian forest on species richness, beta diversity and composition of butterfly species in the Cerrado of Mato Grosso. We tested the hypotheses that: (i) higher species richness and (ii) beta diversity would be recorded in more preserved environments; and (iii) species composition would be more homogeneous in disturbed habitats. For hypothesis testing, the riparian vegetation of eight streams were sampled in four periods of the year in a fixed...

ABSTRACT  This study aimed to evaluate the postharvest quality evolution of gamma-irradiated ‘Tahiti’ limes. Shiny, olivegreen fruits with coarse skin (56 cm equatorial diameter) harvested in commercial orchars and processed in commercial packing house line were used. In a preliminary assay, fruits harvested in April 2011 were exposed to a gamma radiation range from 0 to 750 Gy. The 250 and 750 Gy doses negatively affected skin quality and pulp of exposed fruits. For this reason, new assays were carried out using lower doses to irradiate fruits harvested in July 2011 (off-season) and January 2012 (regular harvest period). Fruit harvested in both periods were selected and exposed to radiation doses of 0, 50, 100, 150, and 200 Gy. All irradiations occurred...

Hancornia speciosa Gomes is a fruit tree native from Brazil that belongs to Apocinaceae family, and is popularly known as Mangabeira. Its fruits are widely consumed raw or processed as fruit jam, juices and ice creams, which have made it a target of intense exploitation. The extractive activities and intense human activity on the environment of natural occurrence of H. speciosa has caused genetic erosion in the species and little is known about the ecology or genetic structure of natural populations. The objective of this research was the evaluation of the genetic diversity and genetic structure of H. speciosa var. speciosa. The genetic variability was assessed using 11 allozyme loci with a sample of 164 individuals distributed in six natural populations...

Autores: Silva,Tanismare Tatiana de Almeida; Guimarães,Renato Mendes; Pinho,Édila Vilela de Resende Von; Abreu,Luciana Aparecida de Souza.
The establishment of citrus orchards with rootstocks from seed with a low physiological quality has been a recurring problem. Low quality seeds directly affect both the final stand and the time required for seedling production. The irregular maturation of fruits, seed recalcitrance, and the high incidence of fungi, make long term storage difficult, even at low temperatures. This study evaluated the storage potential and the use of fungicide treatments on 'Swingle' citrumelo seeds extracted from fruits collected at two maturation stages, green or ripe. The seeds were subjected to a thermal treatment, treated with Derosal, Thiram or Tecto+Captan fungicides, packaged in impermeable polyethylene bags and stored in a cold chamber for nine months. Every three...

Autores: Al-Razi,Hassan; Maria,Marjan; Muzaffar,Sabir Bin.
ABSTRACT Primates are in imminent risk of extinction due to different types of anthropogenic activities. Mortality due to road accidents and electrocution from power lines are among the major direct anthropogenic threats to the survival of primates. We collected primate mortality data from 2015 to 2017 at Lawachara National Park and Satchari National Park in northeastern Bangladesh. We recorded 27 fatalities in five species of primates caused by road accidents (n = 15) and electrocution (n = 12). Most mortality records were for Trachypithecus phayrei (Blyth, 1847) (n = 8) while the lowest recorded mortality was for Macaca mulatta (Zimmermann, 1780) (n = 3). Ninety percent of primates in Bangladesh are threatened and populations are gradually declining. Our...

Quantitative study of Trichodina heterodentata (Ciliophora: Mobilia) infrapopulations infesting tadpoles of a Brazilian endemic toad Rhinella pombali (Anura: Bufonidae)
Provedor de dados: 103
Autores: Fernandes,Noemi M.; Sartini,Bianca; Dias,Roberto J. P.; D'Agosto,Marta.
In this work we investigated the quantitative aspects of the relationship between Rhinella pombali (Baldissera, Caramaschi &amp;amp; Haddad, 2004) tadpoles and their trichodinid ectoparasites. Specimens were collected from a small stream located at an agricultural area between rainforest fragments in southeastern Brazil. A total of 80 tadpoles were investigated. Trichodina heterodentata Duncan, 1977 was the only trichodinid ciliate species recovered. All tadpoles were naturally infested by T. heterodentata with a mean intensity of 695.14 ± 33.33 trichodinid ciliates per tadpole. A positive correlation was observed between the intensity of the infestation and tadpole weight. Intensity of infestation did not significantly influence mean trichodinid diameter...

Downstream passage of fish larvae and eggs through a small-sized reservoir, Mucuri river, Brazil
Provedor de dados: 103
Autores: Pompeu,Paulo S.; Nogueira,Lorena B.; Godinho,Hugo P.; Martinez,Carlos B.
In South America, one important symptom of the failure of fish passages to sustain fish migratory recruitment is the inability of eggs and larvae to reach the nurseries. This is especially so when the breeding areas are located upstream of a reservoir, and the floodplain is downstream of the dam. Therefore, the transport of fish larvae and eggs across reservoir barriers is a key factor in the development of effective conservation strategies. In this paper, we evaluate the potential for migratory fish larvae and egg transportation across a small size reservoir in eastern Brazil. We sampled fish daily between 15th October 2002 and 15th February 2003 (spawning period) in the Mucuri River, immediately upstream of the reservoir and downstream of the Santa Clara...

Autores: Mouga,Denise M.D.S.; Krug,Cristiane.
This study evaluated the bee community and their associated melliferous plants in the northern region of the state of Santa Catarina, Brazil in order to ascertain the diversity and floral interactions of the local Apidae. Twelve samplings were conducted (April 2006 to March 2007) in transects, where nets were used to capture bees directly from their flowers. Voucher specimens for both bees and plants were deposited at UNIVILLE. Diversity and equitability indexes were calculated. Our sampling effort resulted in a total of 934 bees in 72 genera and five families. Forty-four plant species belonging to 19 families were visited. A dominant family in Southern Brazil, Asteraceae, was visited most often (50% of the taxa). Nearly 20% of the plants were visited by...

Autores: Rocha,Carlos F. D.; Siqueira,Carla da C.; Ariani,Cristina V.
Liolaemus lutzae Mertens, 1938 is a critically endangered lizard endemic to the restinga habitat of the state of Rio de Janeiro. We surveyed 25 restinga habitats in order to locate remaining populations, evaluate the status of the species, and determine the nature of local habitat degradation. We found remnant populations of L. lutzae in 18 restinga habitats of six municipalities. The conservation status of each population varied between areas: the population of Grumari, in Rio de Janeiro municipality, is the most preserved and the population of Praia do Forte, in Cabo Frio, is the most disturbed. No L. lutzae were found in Niterói municipality. The most destructive type of habitat degradation identified was the removal of beach vegetation associated with...

Composition of bat assemblages (Mammalia: Chiroptera) in tropical riparian forests
Provedor de dados: 103
Autores: Lourenço,Elizabete Captivo; Gomes,Luiz Antonio Costa; Pinheiro,Michele da Costa; Patrício,Priscilla Maria Peixoto; Famadas,Kátia Maria.
Various studies have focused on the richness and abundance of bats in tropical forests and how the composition of these forests affects bat assemblages, but there are few studies on the relationship of bats with riparian forests. The aim of this study was to ascertain the differences among bat assemblages of three riparian forest areas of the Tinguá region, state of Rio de Janeiro, Brazil. These areas were: I) an agricultural area (Takume); II) a reforested area in primary succession (Canavarro); and III) an area with late secondary vegetation (Tinguá Biological Reserve). Assessments of bat species composition in these areas may shed light on how anthropogenic modifications in riparian forests can influence local bat assemblages. Bats were captured with...

Redescription of Ventania avellanedae (Stylommatophora: Odontostomidae), a land snail endemic to the Ventania Mountain System, Argentina
Provedor de dados: 103
Autores: Pizá,Julia; Cazzaniga,Néstor J.; Ghezzi,Natalia S.
ABSTRACT Although the presence of apertural folds and lamellae is the most recognizable character of the Odontostomidae, some species lack them, mostly in Anctus Martens, 1860, Bahiensis Jousseaume, 1877 and Moricandia Pilsbry &amp; Vanatta, 1898. Eudioptus avellanedae Doering, 1881 - a slender odontostomid species that lacks even the slightest trace of folds or lamellae in its shell aperture - was however transferred to Odontostomus by Pilsbry in 1902 on the basis of its building forward of the aperture-margins. It is currently placed in its own monotypic subgenus, Cyclodontina (Ventania) Parodiz, 1940, on the basis of about the same argument. In this paper we redescribe its shell morphology and, for the first time, describe the internal anatomy of the...

ABSTRACT Leptopanchax opalescens (Myers, 1942) is a small seasonal killifish endemic to coastal drainages in the state of Rio de Janeiro, Brazil. Leptopanchax opalescens was recaptured in temporary open vegetation pools (22°42.35’S, 43°41.59’W) in the hydrographic basin of the Guandu River, state of Rio de Janeiro, Brazil, after eight years without records. Information on habitat and population parameters (Capture per unit area (CPUA), size, sex ratio and length-weight relationship (LWR)) are given to provide subsidies for the conservation of this species. Specimens were captured during the rainy season (January-April 2020) in shallow pools (mean depth = 21 ± 12 s.d. cm), with relatively acidic pH (5.2 ± 0.8) and low concentrations of dissolved oxygen (3.5...

Autores: Maia-Carneiro,Thiago; Dorigo,Thiago A.; Almeida-Gomes,Mauricio; Van Sluys,Monique; Rocha,Carlos F.D.
We analyzed the feeding habits, microhabitat use, and daily activity period of the anuran species Cycloramphus brasiliensis (Steindachner, 1864), endemic to the Atlantic Rainforest biome. The only previous studies on this species focused on the systematics and new altitudinal records. This study was conducted in a large forest remnant located in the municipalities of Guapimirim and Cachoeiras de Macacu. We captured frogs through visual encounter surveys and recorded the frequency of microhabitat types used by them, and the time of capture. Diet was analyzed in terms of number, volume and frequency of occurrence of items. Individuals of C. brasiliensis occurred in association with fast-moving rocky portions of clear freshwater rivers, indicating a...

Provedor de dados: 103
Autores: Magrini,Mariana J; Freitas,André V. L; Uehara-Prado,Marcio.
The Brazilian Atlantic Forest is currently reduced to about 12% of its original range. Among the components that make up its great diversity, there are species with the potential to be bioindicators, which can be very important for conservation-oriented studies. This study compares the species composition, abundance and sex ratio of terrestrial isopods in sites that show different anthropogenic disturbance histories and are located within four reserves in the Atlantic Forest of southwestern Brazil. Our study explores these crustaceans as indicators of anthropogenic disturbance. The influence of one of the following factors was explored in each protected area: 1) history of vegetation harvesting, 2) trail management, 3) Eucalyptus planting, and 4) edge...

Influence of artificial lights on the orientation of hatchlings of Eretmochelys imbricata in Pernambuco, Brazil
Provedor de dados: 103
Autores: Simões,Thyara Noely; Silva,Arley Candido da; Moura,Carina Carneiro de Melo.
ABSTRACT Sea turtle hatchlings, in natural abiotic conditions, emerge from their nests at night and go directly to the sea, following the moonlight’s reflection in the ocean. Increased human activities such as tourism and artificial lights on the coasts, however, have interfered with the ability of sea turtle neonates to find their correct destination, negatively affecting their survival rates. Here we endeavored to assess the influence of artificial lights on the hatchlings of the sea turtle Eretmochelys imbricata (Linnaeus, 1766) in the south coast of the state of Pernambuco, Brazil. To that end, 10 experiments were conducted with 15 hatchlings/test subjects. Five experiments took place in artificially illuminated areas and five in non-illuminated areas....

Provedor de dados: 103
Autores: Hurtado,Natalí; Arias,Edith; Pacheco,Víctor.
Mimon koepckeae Gardner &amp;amp; Patton, 1972 is a poorly-known bat species, with only three known specimens, including the holotype. Its distribution is restricted to the type locality in Ayacucho Department, Peru, and surroundings. This species has been synonymized with M. crenulatum by some authors. Based on a new specimen of M. koepckeae collected from Santuario Nacional Pampa Hermosa, Junin Department, Peru, we provide an extensive morphological comparison with M. crenulatum (Geoffroy St.-Hilaire, 1803), Mimom bennettii (Gray, 1838), and Mimon cozumelae Goldman, 1914, concluding that M. koepckeae is a valid species. As a result the distribution range of the species is extended 160 km north of the type locality. In addition, we characterize the...

Temporal and spatial investments in the protected area network of a megadiverse country
Provedor de dados: 103
Autores: Cabral,Rodolfo; Brito,Daniel.
Protected area networks are the cornerstone strategy for biodiversity conservation worldwide. They are efficient even in the face of human pressures. Brazil is a megadiverse country and for this reason it should not be left out of discussions on biodiversity conservation. Here we present a temporal and spatial analysis of the historical national investments in the country's protected area network. We compare this investment in the light of international biodiversity agreements (e.g., CBD), and evaluate trends and biases in the establishment of protected areas. We obtained the following data from a database maintained by the Brazilian government: the number of protected areas, the dates when they were established, their size and category (strict protection...

Effects of habitat and landscape characteristics on medium and large mammal species richness and composition in northern Uruguay
Provedor de dados: 103
Autores: Andrade-Núñez,María José; Aide,T. Mitchell.
The increasing world population and demand for food and other products has accelerated the conversion of natural habitats into agricultural lands, plantations and urban areas. Changes in habitat and landscape characteristics due to land-use change can have a significant effect on species presence, abundance, and distribution. Multi-scale approaches have been used to determine the proper spatial scales at which species and communities are responding to habitat transformation. In this context, we evaluated medium and large mammal species richness and composition in gallery forest (n = 10), grassland (n = 10), and exotic tree plantation (n = 10) in a region where grasslands have been converted into exotic tree plantations. We quantified mammal species...

Provedor de dados: 103
Autores: Araujo,Helder Farias Pereira de; Rodrigues,Roberta Costa.
Even though the caatinga has been identified as an important area of endemism for South American birds, few studies have been conducted on the distribution, evolution and ecology of birds in this biome. Understanding how habitats contribute to maintain the regional bird diversity is extremely important. In this study, carried out in the backwoods of the state of Alagoas, we present a rapid survey of a caatinga area and discuss the composition of the avifauna in different habitats. From the record of 105 species, we estimated a local richness of 120 (± 5) species. Among the areas surveyed, the dense caatinga shrub areas contributed with more than 42% of the species, holding most of the forest-dependent birds. The open field areas and the vegetation patches...

Provedor de dados: 103
Autores: Cabral,Márcia M. M.; Zuanon,Jansen; de Mattos,Gália E.; Rosas,Fernando C. W.
This study aimed to identify the diet of giant otters, Pteronura brasiliensis (Zimmermann, 1780) in the Balbina reservoir (01º55'S, 59º29'W), to compare it with literature data on the diet of giant otters from non-dammed areas, and to verify the effects of the seasonal changes in water levels on the feeding habits of Balbina otters. A total of 254 feces samples were collected and identified according to the lowest possible taxonomic level. Teleostei fish were present in 100% of the samples; two samples also presented monkey fur (n = 1) and sloth fur (n = 1), suggesting that the diet of P. brasiliensis, in the reservoir, is almost exclusively based on fish. Ten fish families were identified in our samples, six of which were exclusive to the Balbina Lake...

Previous studies have demonstrated that river-based surveys can provide an inexpensive source of information for neotropical zoologists, yet little information is available to inform the application of this technique for the long term monitoring of neotropical turtle species. We aimed to fill this gap by presenting an assessment of data collected during 333 river surveys over 50 months along rivers in a newly protected area in the Peruvian Amazon. A total of 14,138 basking Podocnemis unifilis Troschel, 1848 were recorded during 13,510 km of river-based surveys. We used generalized additive models (GAMs) to explore the influence of a series of abiotic and seasonal variables on the recorded abundances at two temporal scales: monthly and per trip. Our...

Provedor de dados: 103
Autores: Zortéa,Marlon; Brito,Bernardo F. A. de.
The thin-spined porcupine Chaetomys subspinosus (Olfers, 1818) is a species endemic to the extremely disturbed and fragmented Brazilian Atlantic forest. Little is known about its natural history. We analyzed the preferences of porcupine diurnal roost and home range, based on one relocated adult male that was radio-monitored during 1999. The individual was captured in the urban zone of Santa Teresa, Brazil, and relocated to a forest reserve 6 km from the capture site. The thin-spined porcupine feeds only on leaves. It prefers intermediate forest stratum (6-15 m of height) for roosting during daytime, generally using inclined branches with a diameter of 2 to 5 cm. Most observations indicated a prehensile tail position. Home range was relatively large (15.81...

Humpback whale Megaptera novaeangliae (Cetartiodactyla: Balaenopteridae) group sizes in line transect ship surveys: An evaluation of observer errors
Provedor de dados: 103
Autores: Bortolotto,Guilherme A.; Danilewicz,Daniel; Andriolo,Artur; Zerbini,Alexandre N.
ABSTRACT Accurate estimates of group sizes through line transect sampling methods are important to correctly ascertain the abundance of animals that occur in groups. Since the average observed group size is a component of the distance sampling formula, bias in these data leads to biased abundance estimates. This study aimed to evaluate the potential errors in group size estimation during line transect ship surveys to estimate abundances of the humpback whale, Megaptera novaeangliae (Borowski 1781). In a research cruise along the Brazilian coast, an experiment to collect group size information was conducted from two different sighting platforms on the same vessel. Group sizes were recorded by primary observers at first sighting (PO1) and, in some cases,...

Morphological measurements and body indices for Cuban Creole goats and their crossbreds
Provedor de dados: 96
Autores: Chacón,Edilberto; Macedo,Fernando; Velázquez,Francisco; Paiva,Samuel Rezende; Pineda,Eliecer; McManus,Concepta.
In this work, linear body measures were taken and production indices calculated for 100 Cuban Creole goats and 100 crossbred goats in order to aid in the characterization of animal genetic resources in Cuba. Low variation was found for all indices of the Creole goats, showing homogeneity between the groups of animals studied. Most of the functional indices are related to the milk biotype which is in agreement the possible origin of the breed from animals of the Iberian Peninsula and Canary Islands. The crossbreds were more varied, mostly due to undesigned disorganized crossing. These data may help in identifying a commercial niche for the breed and contribute to in situ conservation of the Cuban Creole goat.

Provedor de dados: 96
Autores: Oliveira,Ana Paula Ferreira de; Carvalho,José Herculano de; Miretti,Marcos Mateo; Lara,Maria Aparecida Cassiano; Contel,Eucleia Primo Betioli.
The objective of this study was to describe the genetic diversity and structure of the largest Pé-duro population by assessing variation at ten autosomal microsatellite (STR) loci and mitochondrial DNA (mtDNA) sequences. The mean expected heterozygosity was 0.755, the mean observed heterozygosity was 0.600 and significant inbreeding coefficient (Fis) and deviations from the Hardy-Weinberg equilibrium in most of analyzed loci demonstrate the impact of inbreeding and homozygosis on this population. A more in-depth genetic analysis could be achieved by expanding the STR list. The analysis of mtDNA provided evidence of ancestral African taurine haplotypes in Pé-duro and excluded maternal Zebuine introgression. In this report, the main Pé-duro population is...

Ecological theory and values in the determination of conservation goals: examples from temperate regions of Germany, United States of America, and Chile
Provedor de dados: 97
Autores: Jax,Kurt; Rozzi,Ricardo.
The definition of conservation goals is a complex task, which involves both ecological sciences and social values. A brief history of conservation strategies in Germany (protection of cultural landscapes), United States (wilderness ideal), and southern Chile (preservation paradigm and the more recent interest in ecotourism) illustrates a broad range of conservation goals. To encompass such an array of conservation dimensions and goals, the ecosystem approach adopted by the Conference of the Parties of the Convention on Biological Diversity represents a good approach. However, to become effective, this kind of approach requires clarifying and agreeing upon basic concepts, such as ecosystem. To serve that purpose, we present a scheme that considers the...

Persistence of Dromiciops gliroides in landscapes dominated by Pinus radiata plantations
Provedor de dados: 97
Autores: Uribe,Sandra V.; Chiappe,Romina G.; Estades,Cristián F.
Abstract  Background  Monitos del monte (Dromiciops gliroides) are old-growth forest specialists and, thus, believed to be very sensitive to habitat transformation, although some recent studies show some level of plasticity of their habitat selection patterns.  Findings  In this note we report on records of D. gliroides living in a very modified environment, composed mostly by industrial pine plantations and small fragments of Nothofagus spp. forests and we report the extension of the northernmost limit of its currently known distribution.  Conclusions  Although highly reliant on native vegetation, Dromiciops gliroides has been able to persist in industrial forest landscapes dominated by pine plantations.

Presence of the red jollytail, Brachygalaxias bullocki (Regan, 1908) (Galaxiformes: Galaxiidae), in freshwater forested wetlands from Chile
Provedor de dados: 97
Autores: Correa-Araneda,Francisco; De Los Ríos,Patricio; Habit,Evelyn.
BACKGROUND: Brachygalaxias bullocki (Regan, 1908) is a small-sized freshwater fish species (41 to 46 mm) and endemic to Chile. Its biology has still various knowledge gaps, and its distribution range has been reduced in the last decade due to human intervention. FINDINGS: In this article, for the first time, its presence in forested wetlands of Chile (38°52' to 39°02' S) is documented. The presence of this species in these ecosystems is restricted to wetlands with permanent water regime and depths ranging from 15.7 to 83.5 cm. CONCLUSIONS: The physicochemical habitat conditions show important seasonal variations, suggesting that B. bullocki is resistant to a wide range of temperatures, as well as different levels of dissolved oxygen and conductivity.

Oak canopy arthropod communities: which factors shape its structure?
Provedor de dados: 97
Autores: Valencia-Cuevas,Leticia; Tovar-Sánchez,Efraín.
Canopy of forest ecosystems has been recognized as a habitat that supports a wide variety of plants, vertebrates, invertebrates, and microbes. Within the invertebrate group, arthropods are characterized by their great abundance, diversity, and functional importance. Particularly in temperate forests, species of the genus Quercus (oaks) are one of the most important tree canopy groups, for its diversity and dominance. Different studies have shown that the oak canopy contains a high diversity of arthropods suggesting their importance as habitat for this group of organisms. In this review, we investigated the factors that determine the establishment, organization, and maintenance of arthropod communities in the oak canopy. In general, it was found that there...

Differentiation of Xenarthra (Mammalia) species through the identification of their fecal bile acid patterns: An ecological tool
Provedor de dados: 97
Autores: ARAUJO,M. SOLEDAD; CIUCCIO,MARIANO; CAZON,ADA V; CASANAVE,EMMA B.
The analysis of feces is a fundamental tool for field work, especially to identify the presence of certain species in an area. Fecal bile acids and their relative concentration follow patterns that are species-specific, and can be characterized by Thin Layer Chromatography (TLC). This technique has been used for differentiating feces of several mammal species; however it has never been used for Xenarthra species. In this work, 96 feces of Xenarthra species were analyzed by TLC to determine the bile acid pattern. The species were: Zaedyus pichiy (n = 10), Chaetophractus vellerosus (n = 5), Chaetophractus villosus (n = 57), Dasypus kybridus (n = 4), Priodontes maximus (n = 2), Tamanduá tetradactyla (n = 14) and Myrmecophaga tridactyla (n = 4).

Differential effects of habitat fragmentation on birds and mammals in Valdivian temperate rainforests
Provedor de dados: 97
Autores: KELT,DOUGLAS A.
Four recent studies on Chilean vertebrates underscore the very different effects that habitat fragmentation may have under different conditions. In southern Chile, birds exhibited significant species-area relationships, whereas the more depauperate small mammal community did not. The avifauna of highly isolated rainforest remnants in Fray Jorge National Park (IV Región) presented steeper species-area relations than those in southern Chile, reminiscent of land-bridge islands after faunal relaxation. The small mammal results were unexpected but may reflect the reduced vagility and immigration potential of this group. Additionally, the inter-remnant matrix habitat may support large populations of only some species, allowing them to capitalize on resources...

Evaluating taxonomic homogenization of freshwater fish assemblages in Chile
Provedor de dados: 97
Autores: Vargas,Pamela V; Arismendi,Ivan; Gomez-Uchida,Daniel.
BACKGROUND: Pervasive introductions of non-native taxa are behind processes of homogenization of various types affecting the global flora and fauna. Chile's freshwater ecosystems encompass a diverse and highly endemic fish fauna that might be sensitive to the introduction of non-native species, an ongoing process that started two centuries ago, but has to date received little attention. Using historical (native) and present-day (native and non-native) presence-absence data sets of compositional similarity, our goal was twofold: (1) evaluate patterns of taxonomic homogenization at various spatial scales and (2) identify clusters of widely versus narrowly distributed species to assess their relative role in compositional changes. We expect that non-native...

Diet of the American mink Mustela vison and its potential impact on the native fauna of Navarino Island, Cape Horn Biosphere Reserve, Chile
Provedor de dados: 97
Autores: SCHÜTTLER,ELKE; CÁRCAMO,JAIME; ROZZI,RICARDO.
Invasive exotic species of mammalian predators represent a major cause of vertebrate animal extinctions on islands, particularly those that lack native mammalian carnivores. In 2001, the American mink (Mustela vison) was recorded for the first time on Navarino Island, in the Cape Horn Biosphere Reserve (55° S) in Chile, representing the southernmost population of mink worldwide. In order to assess its potential impact on native fauna, we studied its diet on Navarino Island, as part of an integrative management program on invasive species. Over a three-year period (2005-2007) we collected 512 scats in semi-aquatic habitats: marine coasts, riparian and lake shores. Overall, the main prey was mammals (37 % biomass), and birds (36 %), followed by fish (24 %)....

Long-term monitoring of coastal ecosystems at Las Cruces, Chile: Defining baselines to build ecological literacy in a world of change
Provedor de dados: 97
Autores: NAVARRETE,SERGIO A; GELCICH,STEFAN; CASTILLA,JUAN C.
Marine coastal habitats are being increasingly impacted by human activities. In addition, there are dramatic climatic disruptions that could generate important and irreversible shifts in coastal ecosystems. Long-term monitoring plays a fundamental and irreplaceable role to establish general baselines from which we can better address current and future impacts and distinguish between natural and anthropogenic changes and fluctuations. Here we highlight how over 25 years of monitoring the coastal marine ecosystem within the no-take marine protected area of Las Cruces has provided critical information to understand ecological baselines and build the necessary ecological literacy for marine management and conservation. We argue that this understanding can only...

The economic and environmental impact of trade in forest reserve obligations: a simulation analysis of options for dealing with habitat heterogeneity
Provedor de dados: 123
Autores: Chomitz,Kenneth M.; Thomas,Timothy S.; Brandão,Antônio Salazar P.
A tradeable development rights (TDR) program focusing on biodiversity conservation faces a crucial problem: defining which areas of habitat should be considered equivalent. Restricting the trading scope to a narrow area could boost the range of biodiversity conserved but could increase the opportunity cost of conservation. The issue is relevant to Brazil, where TDR-like policies are emerging. Long-standing laws require each rural property to maintain a legal forest reserve (reserva legal) of at least 20%, but emerging policies allow some tradeability of this obligation. This paper uses a simple, spatially explicit model to simulate a hypothetical state-level program. We find that wider trading scopes drastically reduce landholder costs of complying with...

Autores: Durigan,Giselda; Siqueira,Marinez Ferreira de; Franco,Geraldo Antonio Daher Correa.
Patches of natural vegetation remaining in landscapes occupied by man are continuously under threat due to the edge effects and also to land use types around these remnants. The most frequent threats and land use types in the vicinity of 81 Cerrado (tropical savanna type) fragments in the State of São Paulo, Brazil, were analyzed in order to verify if the frequency of every type of disturbance to the natural ecosystem depends on the neighboring land use. The hypothesis of the study assumes that environmental threats are correlated with land use around protected areas. From the 81 areas, the most frequent human-induced land cover types around the Cerrado remnants were: pasture (recorded in 78% of the areas), sugarcane plantations (26%), roads (19%), annual...

Zeyheria montana, an endemic species of the Bignoniaceae family from the Brazilian Cerrado's known for its anti-cancer properties, is widely used as imuno stimulant in the popular medicine and its therapeutic activity must be validated by scientific data. The objective of this work was to evaluate the genetic variability of eight plant populations collected within the state of São Paulo, Brazil, via Random Amplification of Polymorphic DNA (RAPD) used as molecular markers. After an optimized protocol for the amplification reaction, nine selected primers generated 105 reproducible bands, indicating up to 60% polymorphism. Analysis of molecular variance (AMOVA) revealed higher genetic variation within populations (84.03%) than among populations (15.97%). The...

Autores: Silveira,Luís Cláudio Paterno; Berti Filho,Evoneo; Pierre,Leonardo Santa Rosa; Peres,Fernanda Salles Cunha; Louzada,Julio Neil Cassa.
Onion is the third most grown vegetable crop in São Paulo state, Brazil. Organic onion farming is expected to increase in the state due to the increasing demand. Pest management in organic onion farming is based on plant extracts with insecticide effects. However, the efficacy of such plant extracts has not been proved yet, and it was observed that they do negatively affect natural enemies. Plants surrounding onion fields, and that are attractive to natural enemies, may be a good option to farmers, since they may lead to increased diversity of arthropod species and, consequently, the natural control of pest populations. This study deals with the effect of marigold plants as a resource plant to natural enemies in onion fields. The experiment was set in a...

Autores: Silva,Ana Veruska Cruz da; Freire,Karla Cristina Santos; Lédo,Ana da Silva; Rabbani,Allívia Rouse Carregosa.
Usually known as jenipapo, Genipa americana L. is a Rubiaceae Brazilian native species. It is an important species in the restoration of Brazilian riparian forests and is one of the most promising fruit trees for sustainable harvesting programs. In this study we provide the first data on the genetic diversity and structure of a Jenipapo Germplasm Bank using inter simple sequence repeat (ISSR) markers. We evaluated 160 accessions from wild populations, and the data generated from 12 ISSR primers were used to determine genetic variability via a model-based Bayesian procedure (Structure) and molecular variance analysis. In addition, Shannon index, genetic diversity and Jaccard coefficients were estimated. A total of 12 primers were used, which generated 123...

Autores: Bertoluci,Jaime; Brassaloti,Ricardo Augusto; Ribeiro Júnior,José Wagner; Vilela,Vívian Maria de Faria Nasser; Sawakuchi,Henrique Oliveira.
Neotropical forests show high anuran species richness, but some Brazilian forest formations, like cerradão, semideciduous forests and restingas, remain poorly known. The composition of anuran species were determined for four forest sites belonging to different biomes in southeastern Brazil, based on two complementary techniques (visual encounter survey and survey on breeding sites), both applied simultaneously. A total of 60 anuran species belonging to eight families was recorded. Species richness and levels of endemism were higher in the Atlantic rainforest site. Sites located in the Cerrado domain were more alike than those located in the Atlantic Forest Domain. Similarity in anuran species composition was negatively correlated to the geographical...

Autores: Pérez-Molphe-Balch,Eugenio; Santos-Díaz,María del Socorro; Ramírez-Malagón,Rafael; Ochoa-Alejo,Neftalí.
Cacti species are plants that are well adapted to growing in arid and semiarid regions where the main problem is water availability. Cacti have developed a series of adaptations to cope with water scarcity, such as reduced leaf surface via morphological modifications including spines, cereous cuticles, extended root systems and stem tissue modifications to increase water storage, and crassulacean acid metabolism to reduce transpiration and water loss. Furthermore, seeds of these plants very often exhibit dormancy, a phenomenon that helps to prevent germination when the availability of water is reduced. In general, cactus species exhibit a low growth rate that makes their rapid propagation difficult. Cacti are much appreciated as ornamental plants due to...

Although traditional rice germplasm in northeastern Thailand is only a small portion comparing to modern popular varieties, they are still grown throughout the region. Those traditional varieties grown in the lower part of the region are mostly non-glutinous varieties, while those grown in the upper part are glutinous ones. The existence of these traditional varieties in the region is not only because of growing for sale, but also due to some special reason, such as, believes in their medicinal and nutritional properties, culture and ancestor’s believes. The main objective of this study is to preserve traditional rice varieties for farmers, with the strategic goal of protecting rice germplasm from losses. The experiments were conducted at Sakon Nakhon Rice...

Stingless bees were collected between 1984 and 1990 in continuous forest, forest fragments and cleared areas 90 Km north of Manaus, Amazonas, Brazil. Several methods were employed. a total of 54 species of 21 genera were collected including two undescribed species of Plebeia Schwarz, 1938. The most abundant genera were Trigona Jurine, 1807; Melipona Illiger, 1806; Partamona Schwarz, 1939 and Tetragona Lepeletier, 1825. The most abundant species were Trigona crassipes (Fabricius, 1793) and T. fulviventris Guérin, 1835. Fruit fly traps baited with fragrances for euglossine bees showed to be an useful method for stingless bee collection too. The study area showed a great richness in relation to other regions of the world. However the density of nests found...

Occurrence of Conepatus chinga (Molina) (Mammalia, Carnivora, Mustelidae) and other terrestrial mammals in the Serra do Mar, Paraná, Brazil
Provedor de dados: 104
Autores: Cáceres,Nilton C.
In this paper 19 additional mammalian species are reported in the Atlantic forest of the Paranean Serra do Mar, southern Brazil, including threatened and rare species. These findings resulted from a one-year field research in the western slope of the Serra do Mar, Piraquara municipality, with additional review of reports about mammal distribution in the region. Preliminarily mammal richness in the region is round 54 species, but this number could be higher with more systematic surveys, particularly with regards to bats. The occurrence of the hog-nosed skunk, Conepatus chinga (Molina, 1782), is reported for the first time in the eastern portion of Paraná, a State vastly deforested during the last century in Brazil.

Do captive-born greater rheas Rhea americana Linnaeus (Rheiformes, Rheidae) remember antipredator training?
Provedor de dados: 104
Autores: Azevedo,Cristiano S. de; Young,Robert J.
The antipredator training is a powerful tool now being used to help the reintroduced animals to recognise and escape from their predators. Testing the memory capacity of the animals after antipredator training is important to evaluate if the application of the training is worthwhile. A group of 15 captive-born greater rheas was studied at Belo Horizonte Zoo. Eight birds were antipredator trained and seven birds were not. After the end of the antipredator training sessions, we run four memory tests at 40, 55, 70 and 88 days after training was completed. The memory tests consisted of showing a predator model to the rheas and recording their behavioural responses. It was measured the capacity of antipredator information storage, the influence of the group...

Autores: Soares,Ana Hermínia B.; Araujo,Alexandre F. B. de.
This article examines the results of the introduction into Praia das Neves, state of Espírito Santo, Brazil, of Liolaemus lutzae Mertens, 1938, a lizard species threatened with extinction. Since there are few studies that evaluate how species establish and adapt to new environments, it is useful to assess to what extent the introduction of a critically endangered species into an area similar to where it originally occurred can help reduce its decline in number of individuals and avoid its possible extinction. This study presents the first results of an ongoing monitoring survey set up after the experimental introduction. We analyze how the introduced population uses space and food and we compare these characteristics to that of the original population at...

The Brazilian fish fauna is still poorly known with respect to its diversity and conservation status, particularly of freshwater species. Human activities and population growth are rapidly impacting this fauna to an unchecked extent, so that many fish species are presently threatened. Also, some areas have been so critically altered that their fish fauna can no longer be properly inventoried. There is an urgent need to evaluate the conservation status of Brazilian fish species, since none are presently listed as endangered by federal legislation. Based on a literature search and a survey directed to the Neotropical ichthyologists, we present an unofficial list including a total of 78 threatened fish species (12 elasmobranchs and 66 actinopterygians).

Aves de três remanescentes florestais do norte do Estado do Paraná, sul do Brasil, com sugestões para a conservação e manejo
Provedor de dados: 104
Autores: Bornschein,Marcos Ricardo; Reinert,Bianca Luiza.
One hundred eighty species in a preliminary inventory were identified. From these, 166 were in an area of 832.5 ha (Mata São Francisco State Park), 84 in another of 9.7 ha (Manoel Júlio de Almeida Municipal Forest) and 99 in the third remnant, briefly sampled, of 218 ha (Mata São Paulo). Comparing these numbers to inventories of nearby sites was considered that the larger area is poor in number of bird species, and believe this to be mainly due to the high degree of environmental degradation. Was considered that the smaller area is rich in birds, but its proximity (375 meters) to the third remnant certainly exeits strong influence.

The reintroductions of captive-born greater rheas have been tried but without success; since the individuals reintroduced were killed by predators. Captive-born animals that have been isolated from predators for many generations can lose their predator recognition abilities. To enhance the survival rates of the reintroduced animals, researchers are now using antipredator training techniques. We studied the response of 15 zoo-borne greater rheas to antipredator training. The animals were divided into three groups: two test groups and one control group. We ran 15 antipredator tests and four control testes with each group....

Autores: Branco,Joaquim Olinto.
On the Brazilian coast, those species nest sympatrically, from the islands of Espírito Santo State to Santa Catarina State. From 1999 to 2002 a sampling program was implanted with the objectives of studying the breeding of S. hirundinacea and S. eurygnatha along Santa Catarina coast. The size of colonies in number of couples, reproduction strategy, length, width, weight and the volume of the eggs, as well as bill length and weight of the nestlings were determined. S. hirundinacea youth weight/length relationship was estimated and the reproductive success of the terns colonies was also determined.

Provedor de dados: 36
Autores: FERREIRA,Gisele Cassundé; STURARO,Marcelo J.; PELOSO,Pedro L. Vieira.
ABSTRACT Amazonia harbors the largest and most diverse tropical forest in the world, but knowledge about the species diversity of the region is still far from ideal. Given this low level of faunal and floral knowledge, we present an annotated list of the species of amphibians and reptiles found in Floresta Nacional do Pau-Rosa (FNPR), along the Rio Paraconi, municipality of Maués, state of Amazonas, Brazil. Herpetofauna of the FNPR was sampled with pitfall traps, active search and occasional encounters from February 18 to March 28, 2009. A total of 270 specimens were collected, representing 39 species of amphibians and 24 species of reptiles. At least seven of the species collected at FNPR represented, at the time, unnamed taxa (four of which have now been...

Habitat use, fruit consumption, and population density of the black-headed night monkey, Aotus nigriceps, in southeastern Peru
Provedor de dados: 36
Autores: HELENBROOK,William. D.; WILKINSON,Madison L.; SUAREZ,Jessica A.
ABSTRACT The black-headed night monkey, Aotus nigriceps, has one of the largest distribution ranges of the 11 night monkey species found across Central and South America. Yet, only three studies have focused on their ecology, describing considerable variation in habitat, group composition, and population density. Therefore, we analyzed habitat use, group composition, population density, and diet of 14 groups at two field sites in southeastern Peru. All sampled groups were found in secondary tropical rainforest, often dominated by native bamboo species. Half of the observed sleeping sites were in bamboo stands, though groups also emerged from cane thickets and lianas. This contrasts with other Aotus studies which have found groups living in tree cavities...

Provedor de dados: 36
Autores: MIYAHIRA,Igor Christo; MANSUR,Maria Cristina Dreher; PIMPÃO,Daniel Mansur; COUCEIRO,Sheyla Regina Marques; SANTOS,Sonia Barbosa dos.
ABSTRACT Diplodon granosus was one of the first freshwater mussels to be described for South America. However, the status of the species was confusing for a long time, receiving different taxonomic treatments. In this paper, we redescribe the shell, with new data on the soft parts and information on the distribution and conservation of D. granosus, a rarely recorded species. The shell is thin, not inflated; the macrosculpture is composed only by granules that cover the whole shell, not forming bars; the microsculpture comprises short spikes. In the soft parts we highlight the few, weak and irregularly distributed lamellar connections of the outer demibranch and some features of the stomach, such as the distally enlarged minor typhlosole. There are records...

ABSTRACT The Amazon Basin is a center of diversity of Gossypium barbadense and the strategy for conservation of this genetic resource depends on the knowledge of the diversity maintained in Amazonas State. During two expeditions, in 2012 and 2014, plants were collected in ten municipalities in the state of Amazonas, in the central Brazilian Amazon region. The molecular diversity was estimated by SSR markers for 50 samples collected in 2012. The morphological diversity of 24 plants collected in 2014 was assessed ex situ and compared to that of 50 plants of the same and other cotton varieties from other Brazilian states. Most of plants evaluated in situ in Amazonas had purple petioles and veins (82%), associated to medicinal use, and kidney seeds (78%). The...

ABSTRACT This is the first study to investigate mercury (Hg) contamination in felid species in the Brazilian Amazon. We collected 26 fur samples from wild felids of four species (Puma concolor, Panthera onca, Leopardus pardalis and Leopardus wiedii) occurring in the Mamirauá and Amanã sustainable development reserves, in the state of Amazonas. Samples were from museum specimens, except for five P. onca samples collected from free-living individuals. Total Hg concentrations ranged from 0.12 to 48.1 µg g-1. Concentrations of Hg did not differ significantly between museum specimens and live individuals of P. onca, but varied significantly among species, with significantly higher concentrations for P. onca and L. pardalis, which could be related to factors...

Record of the rare Caribbean mud eel, Pythonichthys sanguineus (Heterenchelyidae, Anguilliformes), in the region of the Amazon Reef
Provedor de dados: 36
Autores: ROTUNDO,Matheus Marcos; MACHADO,Leonardo; OLIVEIRA,Claudio; SANTOS,Wagner César Rosa dos; MARCENIUK,Alexandre Pires.
ABSTRACT As they spend most of their time buried in the substrate and are not a fishery resource, heterenchelyids are seldom seen. These eels are characterized by their greatly reduced eyes, which are covered by semi-transparent skin, the absence of a pectoral fin or lateral line, and no pores on the head or body. Pythonichthys sanguineus is a particularly poorly-known species, with only eight scientific records from Cuba, Puerto Rico, Colombia, Venezuela, Guyana, and Suriname. The present study is based on six adult specimens of P. sanguineus captured by vessels of the shrimp trawling fleet along the northern Brazilian coast, in the vicinity of the Amazon Reef. We provide meristic, morphometric and DNA barcoding data. These findings provide insights into...

Provedor de dados: 37
Autores: BARRIENTOS-MUÑOZ,KARLA G.; RAMÍREZ-GALLEGO,CRISTIAN; PÁEZ,VIVIAN.
The olive ridley (Lepidochelys olivacea) is the most common sea turtle to nest in Colombia. El Valle beach is considered the most important nesting beach for this species in South America. Intensive direct capture of nesting females and egg poaching for consumption and local commercial purposes has been a common practice for years. We conducted an analysis of the nesting ecology of the olive ridley on El Valle beach in the northern Pacific of Colombia in 2008. A total of 164 clutches were transferred to an artificial hatchery for protection. The peak of nesting occurred from the second half of August until the end of September, accounting for 64.6 % of all nests. Along the beach, the section most frequently used was Section 3, with 26 % of the nests. The...

MORPHOLOGY AND CONSERVATION OF THE MESOAMERICAN SLIDER (Trachemys venusta, EMYDIDAE) FROM THE ATRATO RIVER BASIN, COLOMBIA
Provedor de dados: 37
Autores: CEBALLOS,CLAUDIA P.; BRAND,WILLIAM A.
The phylogenetic relationships of the Mesoamerican Slider, Trachemys venusta, that inhabits the Atrato River basin of Colombia have been controversial as three different names have been proposed during the last 12 years: T. v. venusta, T. v. uhrigi, and T. ornate venusta. Using a group of sliders that was confiscated by the regional authority we compared the morphology of T. venusta distributed in the Atrato River with the morphology of the subspecies putatively distributed in Colombia. We found that the Colombian Mesoamerican slider has an overall smaller size, different plastral inter-scute seam formula, and different head, carapace and plastron coloration patterns. In addition, we also report the poor health condition of these individuals that have...

BALANCING CONSERVATION NEEDS WITH USES OF RIVER ECOSYSTEMS
Provedor de dados: 37
Autores: SABATER,SERGI; ELOSEGI,ARTURO.
Rivers are among the most diverse and threatened ecosystems on the Earth, but their conservation is a requisite for sustainable development. Conservation must consider both the structure and the functioning of the elements (usually species), as well as of their ecosystem. Therefore, successful river conservation must go beyond protecting species to protecting entire ecosystems and the processes that give each ecosystem its special characteristics. River conservation has to meet the legitimate aspirations of human populations for clean, readily available supply of water, without compromising the water needs of ecosystems and nature. Therefore, it is essential to take a landscape perspective that incorporates processes occurring in the riverine riparian...

ABSTRACT Shrimp trawling directly impacts target species and non-target species, altering micro-habitats and marine trophic webs. Thus, the objective of the present research was to analyze the feeding habits of Paralonchurus brasiliensis as a tool to evaluate the impact of trawling on the food chains in marine environments, in the South Atlantic of Brazil. One thousand and nineteen stomachs of P. brasiliensis were dissected after being captured as bycatch of shrimp Xiphopenaeus kroyeri, in Penha, on the north central coast of Santa Catarina, Brazil. The number of stomachs was enough to describe the feeding habits of P. brasiliensis, characterizing it as a carnivorous species and predominantly invertivorous. They also revealed that this species has a...

Provedor de dados: 37
Autores: Jiménez-Morera,Ivon; García,Néstor.
ABSTRACT Attalea nucífera is a threatened palm endemic to the Magdalena River basin in Colombia. In the past its seeds were consumed by the inhabitants of the town of Guaduas, Cundinamarca, although currently its use is less frequent. To assess the productive potential of this palm, we studied its phenology, biometric parameters, and fruit productivity in a forest relict in Guaduas. Field work was carried out between April 2016 and March 2017. The reproductive cycle of this species lasted approximately 12 and a half months from bud to fruit ripening. Although bud production occurred throughout the year, it increased during periods of greatest rainfall. Flowering peaks occurred towards the end of the rainy season and fruits ripened towards the period of low...

Autores: Jacobi,Claudia Maria; Carmo,Flávio Fonseca do.
Rock outcrops play an important role in enhancing plant diversity in montane ecosystems. Ironstone outcrops (cangas) are among the lithotypes less known and most threatened in SE Brazil, due to mining activities. Besides species composition, a key feature to promote their conservation and restoration is the knowledge of the community prevalent life-forms, pollination and seed dispersal syndromes. The analyses were done based on published floristic surveys of cangas in SE Brazil. A total of 353 species of angiosperms (70 families) were assigned to one of the two predominant physiognomies (open areas and forest islands) on ironstone outcrops. Sixteen families responded for 70% of all species. Compared to Raunkiaer's spectrum, phanerophytes were over- and...

Autores: Silva,Bruna Gonçalves da; Castello,Ana Carolina Devides; Koch,Ingrid; Silva,Wesley Rodrigues.
ABSTRACT Although impacts generated by gaps can affect vegetation, few studies have addressed these impacts in the Atlantic Forest. Our aim was to investigate the effects of pathways of varying widths on vegetation structure and composition, considering dispersal syndromes, diversity, life forms, successional categories and threatened and exotic species occurrence in the Atlantic Forest. We studied three pathways with widths of 2, 10 and 20 m, intersecting a protected area in southeastern Brazil. To assess edge effects, plots were established adjacent to paths (edge) and 35 m from the edge (neighborhood), and in a control area without pathways. Wider pathways (10 and 20 m) exhibited reduced tree height and diameter, high liana density, exotic species, and...

Serra do Cipó has attracted the interest of many researchers over the years because of its unique characteristics, particularly the fact that the site represents the transition between Cerrado and Atlantic Forest. The study area of Serra do Cipó is located along a gallery forest "córrego Três Pontinhas," at 19°16'00" S and 43°32'49" W and an altitude of 1,188 m. The objective of this study was to survey the Division Bryophyta in a gallery forest within the National Park of Serra do Cipo, Minas Gerais. Collections were made during the months of November 2009 and July 2011. We found 15 families, 26 genera, 43 species, and 4 varieties of mosses. The families with the largest number of species were Leucobryaceae (10), Sematophyllaceae (9), and Calymperaceae...

ABSTRACTFire can change the species composition, diversity, and structure of savanna vegetation, thus altering growth and mortality rates. Such changes in the woody vegetation of burned savanna forest were evaluated over four years in comparison to unburned savanna forest. All woody plants with a diameter at breast height &gt; 10 cm were measured in 100 permanent plots. Six months later, 38 of these plots were burned. Three and a half years later, all surviving individuals were re-sampled. Species richness, diversity, and the number of individuals did not change in the burned plots, although they had significantly higher (p &lt; 0.05) increases in basal area and mortality rates (5.1% year-1) than the unburned plots (3.0% year-1).Tachigali vulgarishad the...

Autores: Endres Júnior,Delio; Sasamori,Márcio Hisayuki; Schmitt,Jairo Lizandro; Droste,Annette.
ABSTRACT Biotic and abiotic factors, such as luminosity, temperature, air humidity, and herbivory, can affect the establishment of reintroduced plants in natural habitats. This study evaluated the effects of these factors on the survival and growth of Cattleya intermedia plants reintroduced into a forest fragment in South Brazil. Plants of C. intermedia were obtained from in vitro seed germination in asymbiotic culture. Eighty-eight plants were reintroduced at both the forest edge and forest interior. Plants with greater shoot heights and number of leaves and pseudobulbs suffered more damage from herbivores at the edge. There were no significant differences in morphometric parameters between damaged and non-damaged plants in the interior. Tenthecoris...

Conservation of species-rich subtropical grasslands: traditional management vs. legal conservation requirements in primary and secondary grasslands
Provedor de dados: 39
Autores: Torchelsen,Fábio Piccin; Cordero,Rodrigo León; Overbeck,Gerhard Ernst.
ABSTRACT Land-use change is the main cause of biodiversity losses, and for grasslands includes changes in management. The last 10 years has seen afforestation of traditionally grazed grasslands increase considerably in the understudied Serra do Sudeste region of the Brazilian Pampa, turning the region into a mosaic of tree plantations, natural ecosystems (partly in conservation areas without grazing management) and other land uses. We evaluated grassland plant community structure and composition in conservation areas considering two distinct types of land-use history and compared them to grasslands under traditional management. The study was carried out at 58 sites. Per site, three plots were established to sample the plant composition of the herbaceous...

Autores: Sühs,Rafael Barbizan; Hoeltgebaum,Marcia Patricia; Nuernberg-Silva,Anelise; Fiaschi,Pedro; Neckel-Oliveira,Selvino; Peroni,Nivaldo.
ABSTRACT Upper montane ecosystems in Brazil are little known, and their structural and functional aspects poorly understood. Our goals were to describe tree species diversity and community structure, and to characterize tree species in relation to their ecological traits, phytogeographic history and conservation status in an upper montane araucaria forest remnant. A total of 26 species belonging to 18 families were found in a 1-hectare permanent plot. The tree community mainly comprised trees with diameters of less than 20 cm and heights of between 6.5 and 9.5 m. Drimys angustifolia and Myrceugenia regnelliana had the highest importance values. Most species were shade tolerant while most individuals were pioneers. Most species and individuals presented...

ABSTRACT Understanding the genetic structure and diversity of plants is fundamental to their conservation and permits their sustainable use by local communities. The genus Maytenus (Celastraceae) is composed of plants possessing pharmacological and antioxidant properties. However, the genetic and economic properties of the species M. dasyclada, a typical species of Araucaria forests in Brazil and Uruguay, have been little studied. In this work, the genetic structure and diversity of natural populations of M. dasyclada located in unprotected and preserved forest remnants were investigated using RAPD and isozymes markers. The results demonstrated that in areas of preservation, populations of M. dasyclada possess a relatively high degree of polymorphism and...

Autores: Machado,Letícia S.; Gonzatti,Felipe; Windisch,Paulo G.
ABSTRACT Community structure and spatial distribution of epiphytic ferns in swamp forest remnants along the coastal plain of the state of Rio Grande do Sul were analyzed. A total of 440 trees were sampled in fifty-seven 10 x 10 m plots. Each phorophyte was divided into five ecological zones (strata), where all species of epiphytic ferns were recorded. A total of 34 species representing 18 genera in six families were recorded. Polypodiaceae was the most represented family with 17 species, and Microgramma vacciniifolia had the highest epiphytic importance value. Characteristic holoepiphyte was the predominant ecological category, representing 70 % of the species. Ordination analysis showed a gradual change in floristic composition between ecological zones...

Autores: Furtado,Samyra Gomes; Menini Neto,Luiz.
ABSTRACT Only a few studies regarding vascular epiphytes have been conducted in mixed ombrophilous forests (MOF) in Serra da Mantiqueira, a mountainous environment in the Brazilian Atlantic Forest, where the relationships of epiphytic flora with other physiognomies are unknown. This study aimed to survey the epiphytes of a MOF remnant located in Serra da Mantiqueira, and to analyze the floristic relationships with ombrophilous forests of the Southern and Southeastern regions of Brazil. The checklist was compared with 51 other areas composed of ombrophilous forests and/or ecotones with other physiognomies using UPGMA (with Sørensen index), and canonical correspondence analysis (CCA). We recorded 138 species, and Orchidaceae and Polypodiaceae were the...

(Taxithelium juruense (Broth.) Broth. (Pylaisiadelphaceae) an endangered Brazilian endemic, with notes on the genus Taxithelium in Brazil). Since its original description, several collections of this species were reported in different states of Brazil. During a revision of the genus, it was confirmed that the geographic range of this species is restricted to the state of Acre, all other reports being based on misidentifications due mostly to the highly polymorphic nature of Taxithelium planum (Brid.) Mitt. Here, we present a more detailed study of T. juruense with characters that will help to distinguish it from T. planum. The misidentifications have obscured the real conservation status of this species, which should be endangered (EN). Key and...

Autores: Fagundes,Bruna Saviatto; Poersch,Maria Augusta; Santos,Jaqueline dos; Gaglioti,André Luiz; Labiak,Paulo Henrique; Muschner,Valeria Cunha.
ABSTRACT Dicksonia sellowiana is the only species of the genus occurring in Brazil. Its distribution is restricted to humid areas of the Atlantic Forest biome. The distribution pattern of biodiversity in this biome is known to have been influenced by historical and environmental factors, although the pattern for ferns remains unknown. This study is first to describe the genetic structure of D. sellowiana along the latitudinal gradient of the Atlantic Forest biome. We use microsatellite markers to estimate genetic diversity and structure for 267 individuals representing 14 populations of D. sellowiana from the Atlantic Forest. The results (Ho, He, Fst, Fis, distance genetic) support the hypothesis of a pattern of biodiversity discontinuity. We found greater...

ABSTRACT Although a species’ sexual system may influence the genetic diversity of its populations in their natural environment, there have been few such studies involving indigenous species of the Atlantic Forest. Here we study Myrsine coriacea, a dioecious tree widely used in reforestation programs despite a lack of information about its natural interpopulation genetic variation. To address this knowledge gap, intra- and interpopulation genetic diversity were measured for male and female individuals of ten natural populations using ISSR markers. Greater intrapopulation genetic diversity indicated interpopulation gene flow, regardless of isolation and distance between populations. Multivariate analyses detected significant differences in genetic diversity...

Temporal changes in species composition, diversity, and woody vegetation structure of savannas in the Cerrado-Amazon transition zone
Provedor de dados: 39
Autores: Maracahipes-Santos,Leonardo; Santos,Josias Oliveira dos; Reis,Simone Matias; Lenza,Eddie.
ABSTRACT Vegetation in the transition between tropical forest and savanna is hyperdynamic and there is evidence that in the absence of fire, forest advances over savanna. Between 2008 and 2013 we evaluated changes in species composition and diversity and in the structure of the woody vegetation of savanna physiognomies in the transition between the Cerrado and Amazon biomes that were fire free for 11 years. The physiognomies form a gradient from savanna woodland (Typical Cerrado - TC), to low woodland (Dense Cerrado - DC), to woodland (locally called Cerradão - CO). We hypothesise that: 1) the more open physiognomies (TC and DC) are more dynamic compared to the closed physiognomy (CO); and 2) in the absence of fire vegetation tends to become more forested....

Autores: Faria,Allan Laid Alkimim; Carvalho-Silva,Micheline; Costa,Denise Pinheiro da; Câmara,Paulo Eduardo Aguiar Saraiva.
Trindade is a Brazilian oceanic island located about 1,200 Km east of the Brazilian coast (between 20º 31' 30" S, 29º 19' 30'' W). The island originated from the abissal zone about 3 million years ago, has a maximum altitude of 620 meters and an area of 9.28 Km². Even though the fanerogamic flora is known, there were virtually no data on the bryophyte flora. Four expeditions to the island were carried out during two years and approximately 431 specimens collected. This work presents the Bryoflora of this island, which comprises 32 species, including 20 species of liverworts distributed among six families; the most speciose being Lejeuneaceae with 11 species and Frullaniaceae with four. There are also 11 species of mosses distributed among eight families,...

Autores: Moreira,Marina Muniz; Barberena,Felipe Fajardo Villela Antolin; Lopes,Rosana Conrado.
Orchidaceae is one of the largest and most diverse plant families in the world. The number of floristic studies of this family in Rio de Janeiro state, Brazil, has increased significantly in recent years. However, only a few such studies have been conducted in areas of restinga vegetation and none of those have examined the similarity, in terms of orchid diversity, among such areas. The present study sought to improve our knowledge of the Orchidaceae diversity occurring in Grumari restinga, as well to compare the diversity of orchids among Grumari and other restinga areas using cluster analysis. We found 15 genera and 19 species. Cluster analysis demonstrated that restingas located on islands are considerably different from those on the mainland, and no...

Few studies address the ecology of herbs of Cerrado grasslands, which are ecosystems where the long dry season, high temperatures, insolation, fire and invasive grasses greatly influencing germination and the establishment of plants. We assessed germination of 13 species of Poaceae from Cerrado grasslands under nursery conditions or in germination chambers, the latter with i) recently collected seeds and seeds after six months storage, ii) under constant and alternating temperatures, and iii) in the presence and absence of light. Germinability, mean germination time (MGT) and required light were quantified to elucidate factors involved in successful germination. Germinability was low for most grasses, probably because of low seed viability. For most...

Twelve years of “Astro” in Sergipe State: in search of harmony between the manatee and the local waterside communities - doi: 10.4025/actascibiolsci.v34i4.10158
Provedor de dados: 3
Autores: Foppel, Ernesto Frederico da Costa; Instituto Mamíferos Aquáticos; Ferrari, Stephen Francis.
The Antillean manatee (Trichechus manatus) is the most threatened aquatic mammal in Brazil. It was considered to be extinct in Sergipe until 1998, when a re-introduced animal (Astro) arrived. Given plans for the re-introduction of more animals, a survey was conducted of the waterside communities of the animal’s home range, on the southern coast of Sergipe. Between March and November, 2009, 27 people were interviewed in 12 communities, using a 14-item questionnaire. All the interviewees knew Astro and were familiar with his behaviour. The primary source of tension between the animal and the community is its habit of approaching vessels and, in particular, fishing equipment. Some fishermen reported that he takes fish from their nets. While most local...

Bird community as an indicator of biodiversity: results from quantitative surveys in Brazil
Provedor de dados: 42
Autores: VIELLIARD,JACQUES M. E.
This short review presents the results obtained in several localities of Brazil on the composition of forest bird communities. Data were collected since the late 80's, after we introduced a new methodology of quantitative survey, based on acoustic identification and unlimited-radius point census. Although these data are still scattered, they show uniquely precise and coherently comparative patterns of composition of forest bird communities. Our methodology has the advantage of being absolutely non-disturbing, highly efficient in the field and immediately processed. Results confirm that the structure of a bird community is a good indicator of biodiversity, particularly useful where biodiversity is high. Many of these data are available only in unpublished...

ABSTRACT The food base in the subterranean environment consists mainly of allochthonous materials. In this environment the resources are distributed generally in a heterogeneous dispersed way and the distribution of resources and their availability determine where the terrestrial invertebrates will reside, which is important for understanding ecological relationships and to establish conservation strategies. Thus, we tested how the complexity of substrates influences the richness and composition of the subterranean terrestrial invertebrates in the Presidente Olegário karst area, southeastern Brazil. We carried out collections in six caves during both dry and wet seasons, using combined collection methods. We observed different distributions in relation to...

Abstract: Amazonia has been a focus of interest since the early days of biogeography as an intrinsically complex and extremely diverse region. This region comprises an intricate mosaic that includes diverse types of forest formations, flooded environments and open vegetation. Increased knowledge about the distribution of species in Amazonia has led to the recognition of complex biogeographic patterns. The confrontation of these biogeographic patterns with information on the geological and climatic history of the region has generated several hypotheses dedicated to explain the origin of the biological diversity. Genomic information, coupled with knowledge of Earth’s history, especially the evolution of the Amazonian landscape, presents fascinating...

The aim of this study was to test the effect of different temperatures on the germination of M. violaceus. Three treatments were conducted: a constant temperature of 25ºC, a 20-35ºC alternating temperature, both inside germination chamber, and an alternating temperature under room temperature (mean temperature ranged from 25-37ºC). The final seed germination rates at the alternating temperature treatments were not significantly different (65% in the seed germinator and 62.5% at room condition). However, both treatments with alternating temperatures had significantly higher germination rates compared to the treatment kept at...

Flower morphology, nectar features, and hummingbird visitation to Palicourea crocea (Rubiaceae) in the Upper Paraná River floodplain, Brazil
Provedor de dados: 42
Autores: Mendonça,Luciana B.; Anjos,Luiz dos.
We investigated flower morphology, nectar features, and hummingbird visitation to Palicourea crocea (Rubiaceae), a common ornithophilous shrub found in the riparian forest understory in the Upper Paraná River floodplain, Brazil. Flowers are distylous and the style-stamen dimorphism is accompanied by other intermorph dimorphisms in corolla length, anther length, and stigma lobe length and form. We did not observe strict reciprocity in the positioning of stigma and anthers between floral morphs. Flowering occurred during the rainy season, October to December. Nectar standing crop per flowerwas relatively constant throughout the day, which apparently resulted in hummingbirds visiting the plant throughout the day. Energetic content of the nectar in each flower...

Provedor de dados: 42
Autores: LICARIÃO,MORGANA R.; BEZERRA,DANDARA M.M.; ALVES,RÔMULO R.N.
Birds are one of the animals most widely used by humans and are highly valued as pets. The present work reports the use of wild birds as pets in the city of Campina Grande, Paraíba State (PB), Brazil. The owners' choice and perceptions of the species ecology was assessed as well. The methodology employed included unstructured and semi-structured interviews, guided tours and direct observations. A total of 26 bird species distributed among ten families and four orders were identified. The most frequently encountered order was Passeriformes (76.9%), with a predominance of the family Emberizidae (34.6%). The specimens kept as pets were principally obtained in public markets or between the breeders themselves. The popularity of birds as pets, compounded by the...

Biodiversity of Coreoidea and Pentatomidae (Heteroptera) from Atlantic forest protected areas. Insights into their conservation.
Provedor de dados: 42
Autores: DELLAPÉ,GIMENA; COLPO,KARINE D.; MELO,MARÍA C.; MONTEMAYOR,SARA I.; DELLAPÉ,PABLO M.
ABSTRACT Although the majority of threatened species are likely to be tropical insects, knowledge of the diversity, ecological role and impact of insect biodiversity loss on ecosystem processes is very limited. Specimens belonging to four families of Heteroptera: Pentatomidae, Coreidae, Alydidae and Rhopalidae, were collected from a protected area in the Paraná Forest, the largest ecoregion of the Atlantic Forest, in Argentina. The assemblages were characterized and the biodiversity estimated, and they were compared with the assemblages found in five other protected areas in the Brazilian Atlantic Forest. In our study area, Pentatomidae had the greatest richness and diversity; Coreidae was the second most diverse family, with highest sampling deficit,...

Species richness and relative abundance of birds in natural and anthropogenic fragments of Brazilian Atlantic forest
Provedor de dados: 42
Autores: Anjos,Luiz dos.
Bird communities were studied in two types of fragmented habitat of Atlantic forest in the State of Paraná, southern Brazil; one consisted of forest fragments that were created as a result of human activities (forest remnants), the other consisted of a set of naturally occurring forest fragments (forest patches). Using quantitative data obtained by the point counts method in 3 forest patches and 3 forest remnants during one year, species richness and relative abundance were compared in those habitats, considering species groups according to their general feeding habits. Insectivores, omnivores, and frugivores presented similar general tendencies in both habitats (decrease of species number with decreasing size and increasing isolation of forest fragment)....

Are eucalypts Brazil's friend or foe? An entomological viewpoint
Provedor de dados: 44
Autores: Majer,Jonathan D.; Recher,Harry F.
Vast areas of Brazil are being planted to Eucalyptus in order to provide renewable sources of timber, charcoal and cellulose. Although the rapid growth and productivity of various Eucalyptus species undoubtedly relaxes the pressure on logging of native forests, there are ecological costs. Firstly, some eucalypt species are vulnerable to pest outbreaks. A large number of native Lepidoptera, Coleoptera and leaf-cutting ants (Atta spp.), some of which have become pests, have been found on eucalypts growing in Brazil. Probably, the diverse myrtaceous flora of South America supports a fauna that can adapt to the introduced Eucalyptus species. Secondly, the leaf litter produced under Eucalyptus plantations differs substantially from that of native forests both...

Is the Murciano-Granadina a single goat breed? A molecular genetics approach
Provedor de dados: 45
Autores: Martínez,A.M.; Vega-Pla,J.L.; León,J.M.; Camacho,M.E.; Delgado,J.V.; Ribeiro,M.N.
The population structure of the Murciano-Granadina breed was determined using 25 microsatellites from 266 goats of seven populations. The results of the genetic differentiation analysis showed that it is possible to differentiate the Murciana and Granadina populations even though a low F ST value (0.0432) had been obtained. Individuals could be assigned to their populations with a success rate of more than 80%. Bayesian-based clustering analysis of allele frequencies and multivariate analysis revealed that Murciana and Granadina populations were grouped in different clusters since K=3. The results demonstrate that Murciana and Granadina are still two different genetic groups included into Murciano-Granadina denomination. There is the opportunity to the...

Autores: Tortorella,R.D.; Modesto,M.R.; Neves,J.P.; Ramos,A.F.
ABSTRACT Two experiments were conducted aiming to evaluate the effects of two ovulatory inducers (Exp.1) and equine chorionic gonadotropin (eCG; Exp.2) on follicular and luteal dynamics in a fixed-time AI (FTAI) protocol in locally adapted Curraleiro Pé-Duro cows. In Exp. 1 multiparous cows (n=12) received an intravaginal device containing 1g of progesterone (P4) for 8 days and 2mg of estradiol benzoate (EB) intramuscularly (IM) at device insertion (Day 0). At device removal (Day 8) 0.150mg of Sodium D-Cloprostenol was administered IM and the cows were randomly assigned to receive 1mg of EB (EB8) or 1mg of estradiol cypionate (EC8) IM, or to not receive any ovulatory inducer (Control). All the animals participated in all treatments (crossover). The...

Autores: Ramalho,Werther Pereira; Andrade,Murilo Sousa; Matos,Lucicléia Railene Assis de; Vieira,Lisandro Juno Soares.
Despite the historical knowledge on amphibians of the Purus River basin, basic information on assemblages is fragmented, with gaps in knowledge existing at various scales, which limits conservation strategies. This study provides information on the composition, richness and abundance of the amphibian fauna in varzea environments and floating meadows of the oxbow lakes of the Middle Purus River between the Boca do Acre and Pauiní municipalities, Amazonas, Brazil. We sampled six oxbow lakes using forty-seven 200-meter transects, distributed among the "floating meadows," "high varzea" and "low varzea," from April to January 2014. We recorded 59 species, with the family Hylidae being predominant. This amphibian fauna represents approximately 19% of the species...

Endemic angiosperms in Bahia Coastal Forests, Brazil: an update using a newly delimited area
Provedor de dados: 49
Autores: Ostroski,Piera; Saiter,Felipe Zamborlini; Amorim,André Márcio; Fiaschi,Pedro.
Abstract: The forest along the coast of Bahia state, in northeastern Brazil, has been acknowledged as an area of endemism for several groups of organisms. The first study concerning endemic angiosperm species in this region, through which 395 taxa were registered, was conducted 15 years ago. However, this number is probably underrated. In this article, we present an updated checklist of angiosperm taxa in Bahia Coastal Forests (BCF) based on geographic distribution data available from the Brazilian Plant List (Flora do Brasil 2020). The records were checked in herbaria, recent taxonomic literature, and, when necessary, reviewed by experts. The final checklist consists of 547 taxa endemic to BCF, distributed in 69 families, with seven endemic genera:...

Abstract: Demersal fishery resources are abundant on continental shelves, on the tropical and subtropical coasts, making up a significant part of the marine environment. Marine demersal fishery resources are captured by various fishing methods, often unsustainably, which has led to the depletion of their stocks. In order to inventory the marine demersal ichthyofauna on the Southern Brazilian coast, as well as their conservation status and distribution, this study analyzed the composition and frequency of occurrence of fish captured by pair trawling in 117 fishery fleet landings based in the State of São Paulo between 2005 and 2012. The ichthyofauna consisted of 245 species (81 families, 32 orders and 2 classes). Among the species, 50 species were...

A review on macrobenthic trophic relationships along subtropical sandy shores in southernmost Brazil
Provedor de dados: 49
Autores: Pinotti,Raphael Mathias; Minasi,Diogo Marroni; Colling,Leonir André; Bemvenuti,Carlos Emílio.
Main trophic relationships that occur along the exposed sandy shores in southernmost Brazil (∼33° S) are established taking into account several biological compartments operating at morphodynamically distinct environments. Beaches are predominantly of the intermediate type but some stretches of coastline are truly dissipative (Cassino Beach) or tending-to-reflective (Concheiros Beach), presenting thus diverse biological compartments and inhabitant macrobenthic assemblages. Dense concentrations of the surf-zone diatom Asterionellopsis glacialis are responsible - at least for the intermediate shorelines - for the most year-round primary production, sustaining several consumers up to tertiary level. Among them, bivalves Amarilladesma mactroides, Donax...

Abstract: Cloud forest ecosystems contain unique flora and fauna characterized by high levels of richness and endemism. However, this ecosystem is one of the most threatened because of land-use changes stemming from anthropogenic activities. Therefore, biological inventories are necessary to adequately assess the effects of land-use changes on species now and in the future. In this study, we conducted an inventory of plants and terrestrial vertebrates (amphibians, reptiles, birds, and mammals) in three fragments of cloud forest in southwestern Mexico. Field work was carried out for 15 days per biological group during distinct time periods (2005-2008). Conventional methods of species capture and observation were employed to record species. Recorded species...

Little is known about the ichthyofauna from South American coastal plain, specially concerning the Mata Atlântica (Atlantic Forest) rivers and streams, as there are regions little explored which may have non-described or rare species. An example is the Parque das Neblinas, a Natural Patrimony Private Reserve (RPPN) in the Bertioga municipality, São Paulo state, where no ichthyofaunal study had been done before. The park's hydrography is made up by the rio Itatinga with its various tributary streams, which flow into the Itapanhaú river basin. Nine sites were sampled using sieves, seines and gill nets; 1,086 specimens of seven species, three orders and five families were captured.

Provedor de dados: 49
Autores: Araujo,Cybele de Oliveira; Condez,Thais Helena; Bovo,Rafael Parelli; Centeno,Fernanda da Cruz; Luiz,Amom Mendes.
The herpetofauna of São Paulo State, Brazil, can be characterized as the most well-known in the country. However, despite the large number of studies in this area, there are still many sampling gaps within biomes such as the Atlantic Forest that are considered global conservation priorities due to the high rate of endemism and human disturbance. As a result of political and historical pressure, this biome has been reduced to less than 12% of its original extent and, despite its importance for global biodiversity conservation, only a small percentage of its original vegetation cover (1%) has some form of legal protection. This is the case of the Parque Estadual Turístico do Alto Ribeira (PETAR) which, together with the Parque Estadual de Intervales, Parque...

Abstract The Northeastern Atlantic Forest (NAF) has a historic of intense habitat loss and fragmentation. In this context, knowledge of the species from forest remnants is urgently needed and represents a key tool for future studies and conservation strategies. Here, we present the floristic inventory of ferns and lycophytes from the Private Natural Heritage Reserve - RPPN Pedra D'Antas, located in a NAF area. The study area associated with the RPPN Frei Caneca is the Serra do Urubu, which is a hotspot for the diversity of several biological groups in the NAF. We recorded 74 fern species, distributed in 17 families and 46 genera. The most diverse families were Pteridaceae (17 species), Polypodiaceae (14 spp.), Dryopteridaceae (nine spp.) and...

Autores: Thiele,Sabrina Campos; Milcharek,Oscar; Santos,Fábio Luis dos; Kaminski,Lucas Augusto.
This paper presents a list of species of butterflies (Lepidoptera: Hesperioidea and Papilionoidea) sampled in Porto Mauá municipality (27°34’S, 28°40’W), Rio Grande do Sul State, Brazil. Sampling was carried out monthly between March 2008 and March 2009. After 204 net-hours of sampling effort, a total of 1,993 individuals from 253 species were recorded. With a single additional expedition, eight new species were added, reaching a total of 261 species recorded in the region of Porto Mauá. These new reports and the species accumulation curves may indicate a much richer fauna. The distribution of richness among butterfly families is compared with other inventories in seasonal semi-deciduous forest areas in the Atlantic Forest. We also discuss the importance...

Expanding the knowledge about the occurrence of anurans in the highest amphibian diversity area of Atlantic Forest: Parque Estadual da Serra do Mar, São Paulo, Brazil
Provedor de dados: 49
Autores: Silva,Fernando Rodrigues da; Lyra,Mariana Lúcio; Haddad,Célio Fernando Baptista; Rossa-Feres,Denise de Cerqueira.
Abstract The vegetation cover in the Atlantic Forest has been converted to human use or degraded by human activities, which declined the vegetation to 16% of its original extent. Although several protected areas have been created in this Neotropical biome over the past decades, our knowledge of the amphibian species within these areas is still far from adequate. Here, we present lists of anuran species from three different areas of Parque Estadual da Serra do Mar: núcleos Curucutu, Santa Virgínia and São Sebastião. To survey anuran species, we visited six sampling units (two ponds, two streams and two trails inside forest fragments) in each locality. Samplings were accomplished from December 2014 to February 2015, December 2015 to February 2016 and...

Provedor de dados: 49
Autores: Castro,Isai Jorge de; Michalski,Fernanda.
The varzea forests of the estuary of the Amazon River cover 25,000 km2within the states of Pará and Amapá. The mammals of those forests, especially bats, are still poorly known. Hence, the present study aimed at inventorying the bat species from three localities of a varzea forest in the estuary of the Amazon River. Between November and December 2013, we selected 18 sampling sites in the mouths of three tributaries of the Amazon River: the rivers Ajuruxí, Maracá, and Mazagão. We set up ten mist nets (12 x 3 m) along a 150-m linear transect in each sampling site, in a total sampling effort of 38,888 m2.h. We captured 403 individual bats of 40 species and five families. We recorded the families: Phyllostomidae (n = 31 species), Emballonuridae (n = 6...

Phanerogamic flora and phytogeography of the Cloud Dwarf Forests of Ibitipoca State Park, Minas Gerais, Brazil
Provedor de dados: 49
Autores: Moreira,Breno; Carvalho,Fabrício Alvim; Menini Neto,Luiz; Salimena,Fátima Regina Gonçalves.
Abstract: This study was developed in Ibitipoca State Park (ISP), a mountainous massif that stands out in the Serra da Mantiqueira, in the Southeastern Region of Brazil. The vegetation is represented by a phytophysiognomic mosaic where areas of campos rupestres interspersed with cloud dwarf forests predominate, at altitudes of 1100 to 1700 m.s.m. The cloud dwarf forests exist in narrow altitude belts on the mountain peaks, immersed in a layer of clouds. They form a peculiar landscape high in the mountains by the short stature of the arboreal elements and richness of lichens and bryophytes, which develop under constant condensation of humidity, low temperatures, and frequent winds. The objective of the present work was to determine the floristic composition...

Autores: Fracasso,Hélio Augusto Alves; Branco,Joaquim Olinto; Barbieri,Edison.
Cabot's Terns Thalasseus acuflavidus (Latham, 1737) are widely distributed along the Atlantic coast of South America from the Caribbean Islands (12º S) to the region of Porto Deseado, Argentina (46º S). Daily observations were conducted on the Cardos Island during 2003, 2005 and 2006 to determine timing and nesting success, and the reproductive biology of the Cabot's Terns nesting there. The first adults arrived at the colony from 22 April to 15 May during the three years recorded; a total of 144 nests were recorded in 2003, 174 in 2005 and 50 in 2006. Observed incubation time was 24.1 ± 0.35 days, and mean egg size was 5.15 ± 0.02 cm in length and 34.30 ± 0.25 g in weight. Hatching success was lowest in 2003 and highest in 2006, with natural causes (such...

Provedor de dados: 49
Autores: Romero,Renato de Mei; Ceneviva-Bastos,Mônica; Baviera,Gustavo Henrique; Casatti,Lilian.
We evaluated qualitatively and quantitatively the community structure of aquatic insects (Ephemeroptera, Plecoptera, and Trichoptera) in 19 streams in areas of Cerrado in the Paraguay, Paraná, and São Francisco river basins. The number of genera and taxonomic composition were compared at spatial (at the hydrographic basins level) and conservation levels (more preserved and less preserved areas). The influence of spatial and environmental factors in richness and abundance was also evaluated. The geographical distribution of Grumicha, Coryphorus, and Austrotinodes was expanded. The highest Trichoptera richness was found in the São Francisco river basin (F = 5,602, p = 0,004) and a higher number of Ephemeroptera genera occurred in the relatively less...

Vanilla bahiana Hoehne (Orchidaceae): studies on fruit development and new perspectives into crop improvement for the Vanilla planifolia group
Provedor de dados: 49
Autores: Nascimento,Tailane Alves do; Furtado,Maura da Silva Costa; Pereira,Wanderson Cunha; Barberena,Felipe Fajardo Villela Antolin.
Abstract: Vanilla is the most well-known and economically important genus of Orchidaceae in the world. Vanilla bahiana is restricted to Brazil and its conservation status was recently assessed as ‘Endangered’. The species is phylogenetically closely related to V. planifolia, whose pods are the main natural source of vanillin. The primary desirable traits for vanilla production are high fruit set and great resistance to abiotic stress. High temperatures (&gt; 32ºC) and heavy rain favor fungal infection, and thus are indirectly responsible for fruit drop by V. planifolia in cultivation. The aim of the present study was to follow the process of pod ripening of V. bahiana in a restinga fragment in an Environmental Protection Area of Bahia State, and to...

Abstract: Human-modified landscapes (HMLs) are composed by small, isolated and defaunated forest fragments, which are surrounded by agricultural and urban areas. Information on species that thrives in these HMLs is essential to direct conservation strategies in local and regional scales. Since HMLs are dominant in the Atlantic Forest, we aimed to assess the mammalian diversity in a HML in southeastern Brazil and to propose conservation strategies. We collected data of terrestrial (small-, medium- and large-sized) and volant mammals in three small forest fragments (10, 14 and 26 ha) and adjacent areas, between 2003 and 2016, using complementary methods: active search, camera trapping, live-traps, mist nets and occasional records (i.e., roadkills).

Wild vertebrate roadkill in the Chapada dos Veadeiros National Park, Central Brazil
Provedor de dados: 49
Autores: Braz,Vívian da Silva; França,Frederico Gustavo Rodrigues.
Chapada dos Veadeiros National Park is one of the most important protected areas of the Brazilian Cerrado and is inhabited by diverse species, but the area has seldom been studied. From 2006 to 2008, we studied the impact of roads on wild vertebrates by recording roadkill on the two main roads located in the vicinity of the park. Of 824 killed vertebrates belonging to 138 species that were recorded, the species that were found most often in each vertebrate group were the Schneider's toad (Rhinella schneideri), the grassland sparrow (Ammodramus humeralis), the yellow-toothed cavy (Galea flavidens), and the marbled lancehead (Bothrops marmoratus). The roadkill rate was 0.096 animals km-1. Vertebrate mortality was significantly higher during the wet season....

Drosophilids (Insecta, Diptera) of the Paranã Valley: eight new records for the Cerrado biome
Provedor de dados: 49
Autores: Mata,Renata Alves da; Roque,Francisco; Tidon,Rosana.
The Paranã Valley, located in the Central Brazil Plateau, within the domain of the Cerrado biome, is frequently cited as a center of endemism and diversity. Nonetheless, this region is poorly known, mainly considering its invertebrate fauna. Here, drosophilid flies were used as biological tools to contribute to a broader inventory, whose goals were mapping the Cerrado biodiversity and identifying areas to be conserved. Three previously unsampled areas in the Paranã Valley were sampled. Amongst the 12,297 specimens collected 45 species were identified, which represents 50% of the drosophilid species previously recorded in the Cerrado. Moreover, this sampling presented eight new occurrences for the biome (Drosophila annulosa, D. calloptera, D. papei, D....

Birds at Santa Bárbara Ecological Station, one of the last Cerrado remnants in the state of São Paulo, Brazil
Provedor de dados: 49
Autores: Lucindo,Anderson da Silva; Antunes,Alexsander Zamorano; Kanashiro,Marina Mitsue; Dias,Manoel Martins.
In the state of São Paulo, southeastern Brazil, the phytophysiognomy known as Cerrado takes less than 1% of its original cover. Thus, the establishment and management of protected areas are essential to save a significant sample of biodiversity of this environment in the region. The Santa Bárbara Ecological Station is one of the largest protected areas in São Paulo, and one of the few ones to cover a mosaic with most of the vegetation types of Cerrado. This article aims to increase the knowledge of avifauna in the reserve, showing new bird records and evaluating the association of species to their physiognomies. We carried out surveys from 2008 to 2013, which resulted in the record of 226 species, or 246 when in regard to Willis &amp; Oniki’s works (1981,...

Knowledge on arthropod assemblages in the Brazilian semideciduous dry forest (caatinga) is scarce, despite the increasing exposure to degradation due to human activities such as logging and intensive agriculture. We performed a short-term survey on the diversity of scorpions in two types of caatinga (hipoxerophytic and hiperxerophytic) in Pernambuco State, Northeastern Brazil. A combination of active collection and pitfall traps was used to sample soil scorpions. Six species belonging to two families were registered: Bothriurus asper, Bothriurus rochai (Bothriuridae), Tityus stigmurus, Tityus pusillus, Rhopalurus rochai and Ananteris franckei (Buthidae).

Abstract: This paper presents a study of the hunting activities on Xerente Indigenous Land (XIL) in the Brazilian Cerrado. We used data from a Hunting Monitoring Program from eight villages to evaluate the effects of village age, distance from village to town and season (wet and dry) on the composition of hunted species, animals and biomass killed and availability of preferred game-species. We also assessed for any indication of fauna depletion around the villages. Distance from village to town and season were the only variables which affected composition. Preferred species occured more often in villages closer to the town. However, these villages present strong indications of local game-species depletion. The hunters' great capacity for spatial movement...

Abstract: Wild and domestic animals and their by-products are important ingredients in the preparation of medicines traditionally used in folk medicine, present in various human cultures since antiquity. However, the decline in the number of species in neotropical regions as a result of hunting for various purposes, including food, medicine and magico-religious use, has placed some species - especially endemic species - at risk of extinction. In this context, the present study aimed to identify the wild vertebrate species used in folk medicine in five communities in the region surrounding the Serra do Conduru State Park (PESC), Bahia, Brazil. Forty-five hunter-farmers were interviewed, citing 23 species, from which 17 raw materials are extracted for...

Autores: Brocardo,Carlos Rodrigo; Rodarte,Raisa; Bueno,Rafael da Silveira; Culot,Laurence; Galetti,Mauro.
The Atlantic Forest is one of the most studied Brazilian biomes in relation to its mammalian fauna. However, there is still a series of gaps of knowledge about the distribution and persistence of some of these species which prevents taking adequate conservation measures to better protect the mammals. In order to make the inventory of the non-volant mammalian fauna of the Carlos Botelho State Park (SP), we compiled data of camera trapping, diurnal census, track records, pitfall and live trapping collected over 8 years (2004-2012). We registered a total of 53 species, of which 12 are regionally threatened and one is an exotic species (Lepus europaeus), including the presence of most mammal species expected for the Paranapiacaba Forest Continuum. The high...

Microsatellite markers previously developed for Pitcairnia albiflos Herb. and Pitcairnia geysksii L.B.Sm. were used in cross-amplification tests of five other Bromeliaceae species. Ten (76.9%) out of the 13 evaluated pair of primers had positive results for some of the species tested. The number of polymorphic alleles ranged between two and four in most species. Ho values ranged between zero, in Pitcairnia flammea Lindl. (PaA05), Aechmea ramosa Mart ex Schult &amp;amp; Schult and Billbergia horrida Regel (PaC05), and one in Billbergia euphemiae E. Morren (PaA05, PaA10, PaC05 and PaD07). This study showed that microsatellite markers developed for P. albiflos and P. geysksii effectively amplified the DNA samples of Pitcairnia flammea, Aechmea nudicaulis (L.)...

Abstract This paper presents a checklist of the reef fish fauna of the Anchieta Island State Park, a no-take zone in which no extractive activities are allowed, in Ubatuba, Southeastern Brazil. Data was obtained between 2011 and 2013, mainly through underwater observations with snorkelling and SCUBA, and secondarily using scientific fishing (trawling). Published and unpublished data were also verified and compiled. A total of 103 reef fish species, distributed in 78 genus and 50 families was recorded. Haemulidae was the richest family (n=7 species), followed by Epinephelidae (n=6), Pomacentridae, Carangidae and Tetraodontidae (n= 4 each). Haemulon was also the most speciose genera (n=5), followed by Stegastes, Acanthurus and Mycteroperca (n=3 each)....

Genetic diversity in Mexican wild populations of the Great Curassow (Crax rubra)
Provedor de dados: 49
Autores: Morales-Contreras,Jonathan; Escalante,Patricia; Matías-Ferrer,Noemí.
Abstract The Great Curassow (Crax rubra) is a Neotropical bird with a wide distribution; it is classified under different threat categories and is listed as a vulnerable species by the IUCN. The Official Mexican Standard, the NOM-059-SEMARNAT-2010, indicates that the Great Curassow is a threatened species, and the subspecies Crax rubra griscomi, which is restricted to the island of Cozumel, is classified as critically endangered. Habitat loss and fragmentation, hunting, overexploitation, and illegal trade are among the main factors that have placed the bird at an endangered status. The objective of the present study was to determine the genetic structure and variation of the species within the Mexican populations of Crax rubra by using three mitochondrial...

Provedor de dados: 49
Autores: Frota,Augusto; Deprá,Gabriel de Carvalho; Petenucci,Letícia Machado; Graça,Weferson Júnio da.
Abstract We compiled data on fish fauna of the Ivaí River basin from recent specialised literature, standardised sampling and records of species deposited in fish collections. There were 118 fish species of eight orders and 29 families. Of these, 100 species are autochthonous (84.8%), 13, allochthonous (11.0%) and five, exotic (4.2%). The main causes for the occurrence of non-native species are escapes from aquaculture, introduction for fishing purposes and the construction of the Itaipu hydroelectric plant. The predominance of small and medium-sized Characiformes and Siluriformes, including 13 species new to science, accounts for approximately 11.0% of all species and 13.0% of all native species. About 10.2% of all species and 12.0% of all native species...

Autores: Lemos,Helena Lara; Pinto,José Roberto Rodrigues; Mews,Henrique Augusto; Lenza,Eddie.
We described and compared the floristic composition, richness, species diversity and structure of the tree-shrub component in pairs of Typical Cerrado (Cerrado Típico) and rocky outcrop Cerrado (Cerrado Rupestre) in two localities in Tocantins State. In each locality, we set up 10 plots of 20 × 50 m at a site, the Cerrado Típico and other Cerrado Rupestre, and sampled the individuals with Db30cm ≥ 5 cm. The rocky outcrop Cerrado did not present any trend towards lower richness and basal area compared to the Cerrado on deep soil. Few species occurred across the four sites and only two important species (Anacardium occidentale and Qualea parviflora) in the four vegetation structure were common to both environments assessed. Furthermore, the occurrence of...

Amphibians and reptiles from a highly diverse area of the Caatinga domain: composition and conservation implications
Provedor de dados: 49
Autores: Loebmann,Daniel; Haddad,Célio Fernando Baptista.
We surveyed the herpetofauna from the Complex of Planalto da Ibiapaba (CPI), CE, Brazil, during two years, using five sampling methods and information available in the literature. The amphibians are represented by 38 species distributed into nine families. The reptiles found summed 84 species, distributed into 25 families. Most amphibians collected exhibited wide occurrence along CPI, where we recorded 24 species (63.2%), which occurred at least in 60% of the sampled environments. Reptiles showed a different pattern, since 52 species (62.6%) had a restricted distribution (up to two environments). Sixteen species out of 25 considered as rare in CPI are restricted to relict moist forests. We also applied a rarity-vulnerability index to determine the most...

Abstract Heliconius nattereri C. Felder &amp; R. Felder, 1865 is an enigmatic and rarely collected species. Because of severe habitat reduction, the species is currently listed as endangered. We here report the confirmation of a northernmost population. This collection and further observations reported here add two more known localites to the distribution of the species. Two of the three confirmed locations are in protected areas. We worry that the northern population may be at great risk because it is not formally protected. We urge conservation efforts to preserve the local forests where the species is found.

Abstract The Bare-faced Curassow Crax fasciolata (Cracidae:Cracinae) is a vulnerable species that was classified as critically endangered by the São Paulo State -Brazil, in 2008. Specialists recommended "searches for areas where there may be a few remaining populations and protection of the last remaining semideciduous forest in the State". Protected areas were investigated in the Cerrado and semideciduous forest in São Paulo State by camera trapping to evaluate the presence of the Bare-faced Curassow. Eight protected areas in Cerrado biome were investigated, but the Bare-faced Curassows was recorded only at Furnas do Bom Jesus State Park (2,069 ha), São Paulo State despite the large sampling effort in larger protected areas such as the Santa Bárbara...

Effects of riparian vegetation on the structure of the marginal aquatic habitat and the associated fish assemblage in a tropical Brazilian reservoir
Provedor de dados: 49
Autores: Beltrão,Gabriel de Barros Moreira; Medeiros,Elvio Sergio Figueredo; Ramos,Robson Tamar da Costa.
Riparian zones represent areas of strong biological, physical and chemical interaction between terrestrial and aquatic ecosystems. These areas are usually typified by high diversity of fauna, flora and environmental processes. The present study evaluates the littoral habitat structure and its fish fauna related to associations between presence and absence of natural riparian vegetal cover, in a reservoir in northeastern Brazil. Sampling was performed on marginal areas where riparian vegetation was present and where it had been removed for the plantation of sugar cane. For each type of marginal area three replicate sites were sampled during the wet season. Data on the habitat structure (submerged elements and substrate composition), fish and water quality...

Predator-prey interaction between two threatened species in a Brazilian hotspot
Provedor de dados: 49
Autores: Canale,Gustavo Rodrigues; Bernardo,Christine Steiner São.
Conflicts in conservation may arise if two or more threatened species are involved in prey-predator interaction. Predators may have a profound effect on small prey populations, thus conservation actions must consider inter-specific interactions involving threatened species. Here we report nest predation events on a wild population of the Endangered red-billed curassow Crax blumenbachii Spix, 1825 by a group of the Critically Endangered yellow-breasted capuchin monkeys Sapajus xanthosternosWied-Neuwied, 1820 in the Brazilian Atlantic Forest. This is the first study to report egg predation of an threatened gamebird by an threatened primate. We recommend that systematic conservation planning for these threatened species consider interactions, especially...

Provedor de dados: 53
Autores: Bron,Ilana Urbano; Jacomino,Angelo Pedro; Pinheiro,Ana Luiza.
The 1-methylcyclopropene (1-MCP) has been used to extent postharvest life of various species. Generally, 1-MCP effectiveness decreases when applied in fruits at advanced ripening stages. The aim of this work was to verify the influence of ripening stages on some physical and chemical attributes of 'Golden' papaya treated with 1-MCP. Papayas were harvested at five ripening stages and treated with 100 nL L-1 of 1-MCP during 12 hours at 23ºC. Fruit skin color and pulp firmness were daily analyzed while soluble solids, titratable acidity and ascorbic acid were evaluated when fruit reached the consumption firmness (20 N). 1-MCP delayed firmness loss during fruit ripening of all ripening stages. The use of 1-MCP prejudices the softening of fruit harvested at...

Marmosets (Callithrix spp.) have been introduced widely in areas within Rio de Janeiro state assigned for the reintroduction of the endangered golden lion tamarin (Leontopithecus rosalia). The objetives of this study were to estimate the marmoset (CM) population in two fragments with reintroduced golden lion tamarin to quantify the association and characterize the interactions between species. The CM population density (0,09 ind/ha) was higher than that of the golden lion tamarin (0,06 ind/ha). The mean association index between tamarins and marmosets varied among groups and seasons (winter=62% and summer=35%). During the winter, competition resulted in increases in territorial and foraging behavior when associated with marmosets. Evidence of benefits...

Autores: Pinheiro,Hudson Tercio; Martins,Agnaldo Silva; Gasparini,João Luiz.
Visual records, radio interviews and onboard observations of the fishing activities during a 58 days scientific expedition to Trindade Island and the Martin Vaz Archipelago were obtained from February to April 2007. The regular activities of four different fisheries were observed: pelagic longline, bottom line, trolling and handline. These fisheries caused mortality of at least seven species with some level threat, according to the International Union for Conservation of Nature list. The establishment of specific restriction norms for hook-and-line activities around the oceanic islands was seen as an alternative for the conservation of the ichthyofauna of the region. Satellite monitoring to track the fishery vessels could be established through the...

In vitro culture of Vriesea gigantea and Vriesea philippocoburgii: two vulnerable bromeliads native to Southern Brazil
Provedor de dados: 52
Autores: Droste,Annette; Silva,Anelise Machado da; Matos,Adriana Vieira; Almeida,Júlia Winck de.
Micropropagation studies were carried out using the seeds for establishing an in vitro culture of Vriesea gigantea and Vriesea philippocoburgii. Germination rate of V. gigantea was higher than of V. philippocoburgii. Plantlets of V. philippocoburgii gave rise to many adventitious shoots when cultivated in Knudson basal medium. In contrast, for V. gigantea, a higher salts-concentration was needed, so that the number of shoots was increased by Murashige and Skoog medium. Addition of activated charcoal and naphthaleneacetic acid in regeneration medium allowed the growth of shoots and the formation of roots, confirming the success of in vitro culture. The differences in expression of the genotypes reinforce the need of more research in order to set up the...

The importance and protection of mangrove ecosystems has been recognized in Brazilian Federal law since 1965. Being protected in law, however, has not always guaranteed their protection in practice. Mangroves are found in coastal and estuarine locations, which are prime real estate for the growth of cities, ports and other economic activities important for Brazilian development. In this mini-review we introduce what mangroves are and why they are so important. We give a brief overview of the microbial diversity found in mangrove sediments and then focus on diversity studies from Brazilian mangroves. We highlight the breadth and depth of knowledge about mangrove microbial communities gained from studying Brazilian mangroves. We report on the exciting...

ABSTRACT: Cryopreservation of testicular tissue enables the maintenance of reproductive capacity in different animal species, and contributes to the formation of gene banks for endangered species. The spermatogonia present in the testes can be grown in vitro and the sperm obtained can be used in artificial breeding programs. This review aimed to describe the main techniques of testicular cryopreservation, the main cryoprotectants used, as well as the progress made in different animal species thus far. In the last decade, significant progress has been made in obtaining viable and functional germ cells from testicular tissue. However, more research is needed to better establish protocols that can be used in clinical practice with various species.

ABSTRACT: Brycon orbignyanus, popularly known in Brazil as piracanjuba, is a fish with great economic value but whose natural population drastically decreased in number during the last years. In this context, genetic variability studies of natural stocks and in restocking programs are fundamental for the adoption of conservation measures. Current analysis verifies the cross-amplification of heterologous primers in B. orbignyanus. Fifty-two primers of the species Brycon opalinus, Brycon hilarii, Brycon insignis, Prochilodus sp., Piaractus mesopotamicus, Colossoma macropomum and Oreochromis niloticus were tested. Primers with the best reproducibility were applied to a sample of 20 individuals and the genetic parameters were calculated. Nine primers provided...

Provedor de dados: 65
Autores: Zhang,Zhenguo; Zhou,Jun.
ABSTRACT:  Biodiversity plays a key role in human welfare by providing agricultural, economic, and health benefits. However, following the industrial revolution, the rapid expansion of the human population and subsequent economic activities have caused a dramatic loss in global biodiversity, resulting in significant disturbances to ecosystems and our own living conditions. Accordingly, the conservation of biodiversity has become one of the most important challenges for humanity. The vast numbers of plants, animals, and microorganisms, the enormous genetic diversity of these species and the different ecosystems to which these organisms belong are all part of a biologically diverse planet. A substantial proportion of the world’s biodiversity has been...

The purpose of this paper was to study the storage of the residue from the extraction of cassava starch without the use of storage technologies, through chemical evaluation, pH values, temperature, development of microorganisms and mycotoxins. A randomized block design was used with eight treatments (different storage periods: 0, 3, 6, 9, 12, 15, 18 and 21 days) and five replications. There was a significant difference for DM content, as a function of days in storage. The chemical composition of the residue from the extraction of cassava starch did not changed throughout the storage period. A negative linear effect was obtained for the pH values, which decreased with days in storage. There was significance of the storage period only for the fungus and...

Adventitious shoots from nodule cluster cultures of Vriesea reitzii: an endemic and endangered bromeliad from atlantic forest
Provedor de dados: 65
Autores: Rech Filho,Arlindo; Vesco,Lírio Luiz Dal; Guerra,Miguel Pedro.
The Atlantic Forest is a biome with megadiversity and a number of bromeliads take part of it. This is the case of Vriesea reitzii, an endemic bromeliad threatened with extinction. Tissue culture techniques are valuable tools for the mass propagation of bromeliads, thus reducing pressure in the natural habitat. The aim of the present work was to establish an in vitro protocol based on the induction and proliferation of nodule cluster cultures of this species. Plantlets maintained in MS liquid culture medium plus NAA (2µM) and BAP (4µM) had the basal regions of leaves excised and then inoculated in gelled with agar (7g L-1) MS culture medium plus with Dicamba (2.5; 5; 10; 20 e 30µM) and Kin (2µM) or free of plant growth regulators. Nodule cluster cultures...

ABSTRACT:  Brycon gouldingi is a species of neotropical fish of socioeconomic and environmental importance in the Tocantins-Araguaia Basin. Genetic studies on this species are still limited, making it difficult to evaluate the population structure and genetic diversity in natural and captive stocks. Here, we aimed to evaluate the transferability of heterologous microsatellite primers in B. gouldingi. A total of 30 primers for eight species were evaluated: Brycon hilarii, Brycon opalinus, Brycon cephalus, Brycon orbignyanus, Prochilodus lineatus, Prochilodus argenteus, Piaractus mesopotamicus, and Colossoma macropomum. The primers that showed the best amplification patterns were applied to 20 specimens of B. gouldingi, and their genetic parameters were...
