A QUESTÃO AMBIENTAL: FLORESTAS E BIODIVERSIDADE
Provedor de dados: 25
Autores: Bertolino, Maria Lúcia.
This work has as objective to argue the environmental question concerning the conservation of the forests and biodiversity. One major issue in this question is that the Brazilian forest sector contributes with an important parcel for the Brazilian economy, generates products for direct consumption or for exportation, generates taxes and jobs for the population and, still, bring positive and negative consequences in the conservation and preservation of both renewable and not renewable natural resources. The forest economy has been, historically, responsible for one of the five largest positive commercial balances of the country and still it supplies 85% of all the products of forest origin found in the national market, therefore, alleviating the pressure on...

Avifauna em florestas tropicais fragmentadas: indicadores da sustentabilidade em Usinas Hidrelétricas
Provedor de dados: 25
Autores: Andrade, Fabiano Timóteo de; Fisch, Simey Thury Vieira; Fortes Neto, Paulo; Batista, Getulio Teixeira.
As florestas tropicais brasileiras em especial a floresta Atlântica e Amazônica foram e continuam sendo alvos constantes de diversas ações antrópicas humanas, que ocasionaram a redução de seus territórios ou ainda sua total fragmentação. Um dos dados mais alarmantes é a perda de sua biodiversidade, que em muitas situações sequer foi conhecida, o que demanda a preocupação com a manutenção sustentável, de forma que várias espécies ainda possam sobreviver. Através de levantamentos na literatura especializada com o tema “o uso de biondicadores na qualidade ambiental em florestas tropicais”, foram elencados os mais utilizados para esse tipo de avaliação com enfoque na avifauna, uma vez que a mesma responde positiva ou negativamente a qualquer fator que altere...

Diversity Of Saprotrophic Anamorphic Ascomycetes From Native Forests In Argentina: An Updated Revi
Provedor de dados: 66
Autores: Allegrucci,Natalia; Cabello,Marta N; Arambarri,Angélica M.
Eight regions of native forests have been recognized in Argentina: Chaco forest, Misiones rain forest, Tucumán-Bolivia forest (Yunga), Andean-Patagonian forest, "Monte", "Espinal", fluvial forests of the Paraguay, Paraná and Uruguay rivers, and "Talares" in the Pampean region. We reviewed the available data concerning biodiversity of saprotrophic microfungi (anamorphic Ascomycota) in those native forests from Argentina, from the earliest collections, done by Spegazzini, to present. Among the above mentioned regions most studies on saprotrophic microfungi concentrates on the Andean-Patagonian forest, the fluvial forests of the Paraguay, Paraná and Uruguay rivers and the "Talares", in the Pampean region. There are only a few records of fungal species in...

Ecosystem service trade-offs and land use among smallholder farmers in eastern Paraguay
Provedor de dados: 7
Autores: Grossman, Jake J.; University of Minnesota: Twin Cities, Department of Ecology, Evolution, and Behavior; gross679@umn.edu.
The trade-off between economically critical provisioning services and environmentally sustaining supporting services often seems absolute. Yet, when land use is inefficient, managers may be able to increase provision of both economically and ecologically sustaining services. To explore such sustainable "win-win" outcomes, I present a model of predicted trade-offs of provisioning and supporting services on smallholder farms in eastern Paraguay. The spatially implicit model simulates smallholder parcels as mosaics of subsistence agriculture, cattle pasture, eucalyptus plantations, and/or natural forest cover, and predicts provisioning and supporting service supply depending on the relative abundance of each land-use type per parcel. I represent provisioning...

Biodiversity conservation continues to be a challenging task for societies worldwide. We undertook a resilience assessment to address the following question: What are the ramifications of social-ecological system dynamics for biodiversity governance of a nationally significant landscape? Resilience assessment offers promise for guiding response strategies, potentially enabling consideration of ecological, social, economic, and governance influences on biodiversity-related activities. Most resilience assessments have, however, struggled to effectively incorporate governance influences. We applied a modified version of the Resilience Alliance workbook approach to explicitly address governance influences at each stage of an assessment of internationally...

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.

China is undergoing economic growth and expansion to a free market economy at a scale and pace that are unprecedented in human history. This is placing great pressure on the country&amp;#8217;s environment and cultural diversity. This paper examines a number of case histories in China, focusing on the culturally varied and ecologically diverse southwest region of the country. We show how developments in recent Chinese history have devalued and in some cases eliminated indigenous knowledge and practices in the quest to strengthen the centralized state. Despite these changes, more than 30 ethnic minorities live in southwest China. For generations these peoples have maintained landscapes through traditional land use and cultural practices. This indigenous...

This paper uses the spatial analysis tools DIVA and FloraMap to identify potential areas for the in situ conservation of a set of 10 forage species. We introduce the idea of roadside verges as conservation areas and discuss the risks and opportunities of two potential scenarios for conservation. These are the introduction of mass reservoirs outside of the original areas of collection and conservation inside the area of origin. Four potential areas for in situ conservation in Latin America are identified. Although more detailed studies using remote sensing, soil information, and field reconnaissance will be necessary for a final assessment of the suggested areas as field conservation sites, we discuss the possibilities of establishing low-maintenance...

Autores: Theobald, David; Colorado State University/The Nature Conservancy; davet@nrel.colostate.edu; Hobbs, N. Thompson; Colorado State University/Colorado Division of Wildlife; nthobbs@nrel.colostate.edu.
Planning activities by local government often seek to identify areas of land that offer particularly high value for conserving biotic resources. Because private land is being developed rapidly, there is heightened concern about identifying these areas. Although general principles on setting priorities for habitat protection are emerging, substantial ambiguity remains about how to implement these principles. Here, we offer a general modeling framework for evaluating how planning alternatives could affect Critical Habitat. The framework contains four components: stakeholder involvement, spatial modeling of Critical Habitat and development patterns, analysis of alternative scenarios, and evaluation and monitoring. We illustrate this approach using a case...

Ecologists and practitioners have conventionally used forest plots or transects for monitoring changes in attributes of forest condition over time. However, given the difficulty in collecting such data, conservation practitioners frequently rely on the judgment of foresters and forest users for evaluating changes. These methods are rarely compared. We use a dataset of 53 forests in five countries to compare assessments of forest change from forest plots, and forester and user evaluations of changes in forest density. We find that user assessments of changes in tree density are strongly and significantly related to assessments of change derived from statistical analyses of randomly distributed forest plots. User assessments of change in density at the...

The need to reduce human impacts on ecosystems creates pressure for adequate response, but the rush to solutions fosters the oversimplification of such notions as sustainable development and ecosystem health. Hence, it favors the tendency to ignore the complexity of natural systems. In this paper, after a brief analysis of the use and abuse of the notion of ecosystem health, we address the problem of a sound definition of ecosystem integrity, critically review the different methodological and conceptual approaches to the management of natural resources, and sketch the practical implications stemming from their implementation. We show thatthere are merits and  limitations in different definitions of ecosystem integrity, for each acknowledges different...

Based on an extensive review of the literature, and broad consultation with experts, we have assessed the sensitivity of Bornean vertebrates to the direct and indirect effects of timber harvest. Well-implemented selective logging has a relatively limited direct impact on wildlife populations: few species appear quite sensitive, some benefit, some decline. However, current management practices in Indonesian Borneo generally cause a decline in wildlife populations. Guidelines for sustainable forest management are primarily focused on trees, with few specific recommendations on how to sustainably manage wildlife populations in timber concessions. Based on our findings, we provide extensive wildlife management guidelines, pointing out the importance of...

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...

The landscape of Mengsong, southwest China, was biologically diverse until recently due to historical biogeographical processes overlain by the swidden-cultivation practices of the Hani who migrated there several centuries ago.  Our research sought to understand how the Hani adjusted their livelihoods to new policies, markets, and technologies, and the consequences for biodiversity conservation.  We combined landscape, plot, and household surveys, interviews, and reviews of secondary documents, to reconstruct the major changes and responses to challenges in the social&amp;#8211;ecological system over previous decades.  Significant changes from closed to open canopy of secondary-forest vegetation took place between 1965&amp;#8211;1993 and from open-canopy...

The effects of land abandonment on biodiversity have received considerable attention by scholars, but results are far from conclusive. Different cultural traditions of scientists seem to underlie the contrasting ways in which land abandonment is understood. Although the forest transition (FT) framework considers land abandonment as an opportunity for biodiversity conservation, European landscape ecologists characterize it as a threat. We use insights from both traditions to analyze the effects of land abandonment on landscape and biodiversity in a mountain area of metropolitan Barcelona. We do so through an in-depth historical case study covering a period of 160 years. A set of landscape metrics was applied to land-cover maps derived from cadastral...

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. We further...

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...

The distribution of functional traits within and across spatiotemporal scales has been used to quantify and infer the relative resilience across ecosystems. We use explicit spatial modeling to evaluate within- and cross-scale redundancy in headwater streams, an ecosystem type with a hierarchical and dendritic network structure. We assessed the cross-scale distribution of functional feeding groups of benthic invertebrates in Swedish headwater streams during two seasons. We evaluated functional metrics, i.e., Shannon diversity, richness, and evenness, and the degree of redundancy within and across modeled spatial scales for individual feeding groups. We also estimated the correlates of environmental versus spatial factors of both functional composition and...

Since the Convention on Biological Diversity in 1992, biodiversity has become an important topic for scientific research. Much of this research is focused on measuring and mapping the current state of biodiversity, in terms of which species are present at which places and in which abundance, and making extrapolations and future projections, that is, determining the trends. Biodiversity databases are crucial components of these activities because they store information about biodiversity and make it digitally available. Useful biodiversity databases require data that are reliable, standardized, and fit for up-scaling. This paper uses material from the EBONE-project (European Biodiversity Observation Network) to illustrate how biodiversity databases are...

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...

Food supply and food distribution have been and are important issues in the global political arena. The recent emergence of biofuel policies has increased the influence of the policy arena on agricultural production. In this paper we show the regional impact of changes in the European Common Agricultural Policy and biofuel policy. Shifting trade patterns, changes in agricultural production, and expansion of agricultural area or intensification of agriculture result in changes in land use and land use emissions. Higher prices for agricultural crops on the world market together with changing production raise agricultural income. Brazil is the region the most affected. The results show that arrangements or policies will be needed to avoid negative impacts in...

We investigated and compared management practices for dealing with uncertainty in agroecosystem dynamics in two cases of smallholder farming in different parts of the world: northeast Tanzania and east-central Sweden. Qualitative research methods were applied to map farmers' practices related to agroecosystem management. The practices are clustered according to a framework of ecosystem services relevant for agricultural production and discussed using a theoretical model of ecosystem dynamics. Almost half of the identified practices were found to be similar in both cases, with similar approaches for adjusting to and dealing with local variability and disturbance.

Will community monitoring assist in delivering just and equitable REDD+? We assessed whether local communities can effectively estimate carbon stocks in some of the world&amp;#8217;s most carbon rich forests, using simple field protocols, and we reviewed whether community monitoring exists in current REDD+ pilots. We obtained similar results for forest carbon when measured by communities and professional foresters in 289 vegetation plots in Southeast Asia. Most REDD+ monitoring schemes, however, contain no community involvement. To close the gulf between United Nations Framework Convention on Climate Change texts on involving communities and field implementation realities, we propose greater embedding of community monitoring within national REDD+ pilot...

Among the strategies to promote sustainable tropical forest development around the world, the Federal Extractive Reserve System of Brazil is widely cited as an exemplary model. It is designed to protect rubber tapper communities, their forests, and their livelihoods while preventing deforestation and conserving biodiversity. In response to changing markets and policies, rubber tappers in the Chico Mendes Extractive Reserve have recently diversified production to include market agriculture and cattle production, precipitating deforestation in the reserve, with the implication of increased ecological degradation compared to the extraction of nontimber forest products (NTFPs). Our remote sensing and forest inventory analyses yield different insights about the...

Autores: Bhar, Rod; Ottawa-Carleton Institute of Biology; rbhar@ccs.carleton.ca; Fahrig, Lenore; Carleton University; lfahrig@ccs.carleton.ca.
Maintenance of woody borders surrounding crop fields is desirable for biodiversity conservation. However, for crop pest management, the desirability of woody borders depends on the trade-off between their effects at the local field scale and the landscape scale. At the local scale, woody borders can reduce pest populations by increasing predation rates, but they can also increase pest populations by providing complementary habitats and reducing movement rate of pests out of crop fields. At the regional scale, woody borders can reduce pest populations by reducing colonization of newly planted crop fields. Our objective was to develop guidelines for maximizing pest control while maintaining woody borders in the landscape. We wished to determine the...

Most assessments of resilience have been focused on local conditions. Studies focused on the relationship between humanity and environmental degradation are rare, and are rarely comprehensive. We investigated multiple social-ecological factors for 100 countries around the globe in relation to the percentage of invasions and extinctions within each country. These 100 countries contain approximately 87% of the world&amp;#8217;s population, produce 43% of the world&amp;#8217;s per capita gross domestic product (GDP), and take up 74% of the earth&amp;#8217;s total land area.

Biodiversity payments have become an increasingly proposed tool to promote conservation measures. An unexplored issue concerns the potential role of fiscal transfers between the state and infra-national authorities potentially as direct financial incentives for biodiversity conservation. We explore how protected areas can be taken into account in a redistributive fiscal transfer system between the state and local authorities, i.e., municipalities. Different simulations were made in the Mediterranean region of southern France, a major biodiversity hotspot subject to increasing threats.

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.

Biodiversity is of crucial importance for ecosystem functioning and human well-being. Using quantitative projections of changes in land use and climate from the four Millennium Ecosystem Assessment (MA) scenarios, we project that reduction of habitat by year 2050 will result in a loss of global vascular plant diversity ranging from 7&amp;#8211;24% relative to 1995, after populations have reached equilibrium with the reduced habitat. This range includes both the impact of different scenarios and uncertainty in the SAR relationship. Biomes projected to lose the most species are warm mixed forest, savannahs, shrub, tropical forest, and tropical woodlands. In the 2000&amp;#8211;2050 period, land-use change contributes more on a global scale to species...

We explore the thesis that stochasticity in successional-disturbance systems can be an agent of species extinction. The analysis uses a simple model of patch dynamics for seral stages in an idealized landscape; each seral stage is assumed to support a specialist biota. The landscape as a whole is characterized by a mean patch birth rate, mean patch size, and mean lifetime for each patch type. Stochasticity takes three forms: (1) patch stochasticity is randomness in the birth times and sizes of individual patches, (2) landscape stochasticity is variation in the annual means of birth rate and size, and (3) turnover mode is whether a patch is eliminated by disturbance or by successional change. Analytical and numerical analyses of the model suggest that...

With the increasing need to reduce greenhouse gas concentrations, afforestation and reforestation (A/R) projects are being implemented under the Kyoto Clean Development Mechanism (CDM) and under the voluntary carbon (C) market. The specific objective of A/R C projects is to enhance terrestrial sinks. They could also provide low-income communities in developing countries with a source of revenue, as well as a number of ecological and social services. However, feasibility issues have hindered implementation of A/R CDMs. We propose enrichment planting (EP) in old fallow using high-value native timber species as a land-use alternative and a small-scale C projects opportunity. We present EP in the context of ongoing work in a poor indigenous community in...

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...

Humans depend on services provided by ecosystems, and how services are affected by climate change is increasingly studied. Few studies, however, address changes likely to affect services from seminatural ecosystems. We analyzed ecosystem goods and services in natural and seminatural systems, specifically how they are expected to change as a result of projected climate change during the 21st century. We selected terrestrial and freshwater systems in northernmost Europe, where climate is anticipated to change more than the global average, and identified likely changes in ecosystem services and their societal consequences. We did this by assembling experts from ecology, social science, and cultural geography in workshops, and we also performed a literature...

Philosophy of ecology has been slow to become established as an area of philosophical interest, but it is now receiving considerable attention. This area holds great promise for the advancement of both ecology and the philosophy of science. Insights from the philosophy of science can advance ecology in a number of ways. For example, philosophy can assist with the development of improved models of ecological hypothesis testing and theory choice. Philosophy can also help ecologists understand the role and limitations of mathematical models in ecology. On the other side, philosophy of science will be advanced by having ecological case studies as part of the stock of examples. Ecological case studies can shed light on old philosophical topics as well as raise...

Ecosystem services are essential for human well-being, but the links between ecosystem services and human well-being are complex, diverse, context-dependent, and complicated by the need to consider different spatial and temporal scales to assess them properly. We present the results of a study in the rural community of Sistelo in northern Portugal that formed part of the Portugal Millennium Ecosystem Assessment. The main purpose of our study was to assess the linkages between human well-being and ecosystem services at the local level, as perceived by the community. We used a range of tools that included participatory rural appraisal and rapid rural appraisal as well as other field methods such as direct observation, familiarization and participation in...

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...

Indigenous and rural communities have developed strategies aimed at supporting their livelihoods and protecting biodiversity. Motivational factors underlying these local conservation strategies, however, are still a largely neglected topic. We aimed to enrich the conceptualization of community-based conservation by exploring trigger events and motivations that induce local people to be engaged in practical institutional arrangements for successful natural resource management and biodiversity conservation. By examining the history and development of three community conservation initiatives in Brazil, Mexico, and Bolivia, we have illustrated and discussed two main ways of understanding community-based conservation from the interaction between extrinsic and...

Serious methodological and policy hurdles constrain effective natural resource management that alleviates poverty while protecting environmental services in tropical watersheds. We review the development of an approach that integrates biodiversity conservation with agroforestry development through the active involvement of communities and their local governments near the Kitanglad Range Natural Park in the Manupali watershed, central Mindanao, the Philippines. Agroforestry innovations were developed to suit the biophysical and socioeconomic conditions of the buffer zone. These included practices for tree farming and conservation farming for annual cropping on slopes. Institutional innovations improved resource management, resulting in an effective social...

International environmental organizations have an increasing commitment to the development of conservation programs in high-diversity regions where indigenous communities maintain customary rights to their lands and seas. A major challenge that these programs face is the alignment of international conservation values with those of the indigenous communities whose cooperation and support are vital. International environmental organizations are focused on biodiversity conservation, but local communities often have a different range of concerns and interests, only some of which relate to biodiversity. One solution to this problem involves adoption of a cultural landscape approach as the ethical and organizational foundation of the conservation program. In our...

We examined bird diversity in relation to land use and socioeconomic indicators in Leipzig, Germany. We used neighborhood diversity (ND) and bivariate correlation to show that the potential to experience biodiversity in a city is associated with population density, household income, unemployment, and urban green space. People living in urban districts with high socioeconomic status experience the highest species richness around their homes, whereas lower social status increases the chance of living in species-poor neighborhoods. High-status districts are located along forests, parks, and rivers that have a high quantity and quality of green space. However, green space in general does not guarantee high bird diversity. We conclude that bird diversity...

Forest degradation is broadly defined as a reduction in the capacity of a forest to produce ecosystem services such as carbon storage and wood products as a result of anthropogenic and environmental changes. The main causes of degradation include unsustainable logging, agriculture, invasive species, fire, fuelwood gathering, and livestock grazing. Forest degradation is widespread and has become an important consideration in global policy processes that deal with biodiversity, climate change, and forest management. There is, however, no generally recognized way to identify a degraded forest because perceptions of forest degradation vary depending on the cause, the particular goods or services of interest, and the temporal and spatial scales considered....

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...

Accelerating environmental change is perhaps the greatest challenge for natural resource management; successful strategies need to be effective for decades to come. Our objective is to identify opportunities that new environmental conditions may provide for conservation, restoration, and resource use in a globally recognized biodiversity hotspot in southwestern Australia. We describe a variety of changes to key taxonomic groups and system-scale characteristics as a consequence of environmental change (climate and land use), and outline strategies for conserving and restoring important ecological and agricultural characteristics. Opportunities for conservation and economic adaptation are substantial because of gradients in rainfall, temperature, and land...

There is an increasing emphasis on the restoration of ecosystem services as well as of biodiversity, especially where restoration projects are planned at a landscape scale. This increase in the diversity of restoration aims has a number of conceptual and practical implications for the way that restoration projects are monitored and evaluated. Landscape-scale projects require monitoring of not only ecosystem services and biodiversity but also of ecosystem processes since these can underpin both. Using the experiences gained at a landscape-scale wetland restoration project in the UK, we discuss a number of issues that need to be considered, including the choice of metrics for monitoring ecosystem services and the difficulties of assessing the interactions...

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...

Autores: Rigoldi,Maria Pia; Rapposelli,Emma; De Giorgio,Donato; Resta,Paolo; Porceddu,Andrea.
Background Sweet-seeded domesticated almonds were brought to the Mediterranean Basin from central Asia about 4000 years ago. In Italy, most of the almonds produced are cultivated in the southern part of the country. Local populations of the tree in Sardinia are largely seed-derived and mostly self-incompatible, so have developed extensive genetic diversity. The need to protect biodiversity has prompted a revived interest in local genetic materials in almond. Two Italian collections have been established, one in Sardinia and the other in Apulia. These collections were the focus of the present evaluation of genetic diversity. Results Eleven SSRs (microsatellites) were used for fingerprinting. The Sardinian germplasm was highly polymorphic, revealing a mean...

The tip of the South American cone is one of the most interesting Subantarctic areas, both biogeographically and ecologically. Nonetheless, knowledge of the area's biodiversity, in particular that of the subtidal marine habitats, remains poor. Therefore, in 2004, a biodiversity research project was carried out as a part of the cruise Cimar-10 Fjords, organized and supported by the Chilean National Oceanographic Committee (CONA). The results of the subtidal marine mollusk surveys are presented herein. The samples were collected aboard the Agor 60 "Vidal Gormaz" in winter 2004. The study area covered the northern Chilean Patagonia from Seno de Relocanví (41°31'S) to Boca del Guafo (43°49'S), on the continental shelf from 22 to 353 m depth. The Mollusca were...

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...

The effect of chilling on seed germination of placea species (Asparagales: Amaryllidaceae), an endemic genus to central Chile
Provedor de dados: 73
Autores: Guerrero,Pablo C; Sandoval,Ana C; León-Lobos,Pedro.
The effect of chilling on germination was examined for six Placea species, a genus in the Amaryllidaceae endemic to the Andes and Coastal Range of central Chile. Based on their natural environment, we hypothesized that low temperatures would be important for germination in theses species. We addressed two questions (i) do Placea seeds require chilling for seed germination? (ii) if they required chilling, does thermal history before chilling affect their responsivity to chilling? At 4ºC seeds of all species germinated faster and to a higher level than at 25ºC. After 28 days, when seeds held at 25ºC were moved to 4ºC, germination increased significantly, however at the end of the assay, their germination was still lower than those seeds initially at 4ºC....

Cytogenetic studies in fishes of the genera Hassar, Platydoras and Opsodoras (Doradidae, Siluriformes) from Jarí and Xingú Rivers, Brazil
Provedor de dados: 74
Autores: Milhomem,Susana Suely Rodrigues; Souza,Augusto Cesar Paes de; Nascimento,Aline Lira do; Carvalho Jr.,Jaime Ribeiro; Feldberg,Eliana; Pieczarka,Julio Cesar; Nagamachi,Cleusa Yoshiko.
We studied the karyotypes of Hassar cf. orestis and an undescribed Hassar species from the Jarí River and Opsodoras ternetzi, H. orestis and Platydoras cf. costatus from the Xingú River, all with 2n = 58. Constitutive heterochromatin is located in the centromere in most metacentric pairs; in some chromosomes this banding is not present, or it is located on the whole chromosome arm or in the distal regions. The NOR is located on a single biarmed pair at a distal region of the short arm in H. cf. orestis, H. orestis and P. cf. costatus at a distal region of the long arm in O. ternetzi and at a proximal region of the long arm in the Hassar species. In all species (except for Hassar sp.) the CMA3 analysis revealed a rich G-C region coincident with the NOR....

Chromosomal diversity in three species of electric fish (Apteronotidae, Gymnotiformes) from the Amazon Basin
Provedor de dados: 74
Autores: Silva,Fernando Henrique Ramos; Pieczarka,Julio Cesar; Cardoso,Adauto Lima; Silva,Patrícia Corrêa da; Oliveira,Jonas Alves de; Nagamachi,Cleusa Yoshiko.
Cytogenetic studies were carried out on samples of Parapteronotus hasemani, Sternarchogiton preto and Sternarchorhamphus muelleri (Apteronotidae, Gymnotiformes) from the Amazon basin. The first two species exhibited both a 2n = 52 karyotype, but differed in their karyotypic formulae, distribution of constitutive heterochromatin, and chromosomal location of the NOR. The third species, Sternarchorhamphus muelleri, was found to have a 2n = 32 karyotype. In all three species the DAPI and chromomycin A3 staining results were consistent with the C-banding results and nucleolar organizer region (NOR) localization. The 18S rDNA probe confirmed that there was only one pair of ribosomal DNA cistron bearers per species. The telomeric probe did not reveal interstitial...

Exploiting a wheat EST database to assess genetic diversity
Provedor de dados: 74
Autores: Karakas,Ozge; Gurel,Filiz; Uncuoglu,Ahu Altinkut.
Expressed sequence tag (EST) markers have been used to assess variety and genetic diversity in wheat (Triticum aestivum). In this study, 1549 ESTs from wheat infested with yellow rust were used to examine the genetic diversity of six susceptible and resistant wheat cultivars. The aim of using these cultivars was to improve the competitiveness of public wheat breeding programs through the intensive use of modern, particularly marker-assisted, selection technologies. The F2 individuals derived from cultivar crosses were screened for resistance to yellow rust at the seedling stage in greenhouses and adult stage in the field to identify DNA markers genetically linked to resistance. Five hundred and sixty ESTs were assembled into 136 contigs and 989 singletons....

Variation in extragenic repetitive DNA sequences in Pseudomonas syringae and potential use of modified REP primers in the identification of closely related isolates
Provedor de dados: 74
Autores: Çepni,Elif; Gürel,Filiz.
In this study, Pseudomonas syringe pathovars isolated from olive, tomato and bean were identified by species-specific PCR and their genetic diversity was assessed by repetitive extragenic palindromic (REP)-PCR. Reverse universal primers for REP-PCR were designed by using the bases of A, T, G or C at the positions of 1, 4 and 11 to identify additional polymorphism in the banding patterns. Binding of the primers to different annealing sites in the genome revealed additional fingerprint patterns in eight isolates of P. savastanoi pv. savastanoi and two isolates of P. syringae pv. tomato. The use of four different bases in the primer sequences did not affect the PCR reproducibility and was very efficient in revealing intra-pathovar diversity, particularly in...

Native plant species with economic value from Minas Gerais and Goiás: a discussion on the currentness of the data recovered by the French naturalist Auguste de Saint-Hilaire
Provedor de dados: 75
Autores: Mügge,Fernanda LB; Paula-Souza,Juliana; Melo,Jean C; Brandão,Maria GL.
ABSTRACT Given the increasing anthropic threats faced by natural ecosystems all around the world, this work holds an important role by recovering primary information of the Brazilian biodiversity. In this study we discuss data collected at a time when the native vegetation in Brazil was still preserved, and the use of plants was primarily made from species of autoctone flora. Those areas were visited by European naturalists in the 19th century, including the French Auguste de Saint-Hilaire, who described the use of numerous native species. The possibility of current economic use of some species cited by him in the 19th century is discussed.

Многолетние трансформации планктона в гиперсолёном Бакальском озере (Крым) при колебаниях солёности.
Provedor de dados: 13
Autores: Загородняя, Ю. А.; Батогова, Е. А.; Шадрин, Н. В.
Изложены результаты исследования планктона в гиперсолёном Бакальском озере в период с 2000 по 2007 гг. Его солёность в эти годы резко менялась, из гиперсолёного оно превращалось в морское и затем возвращалось к гипергалинному состоянию. Такие изменения солёности приводили к полной смене фауны (галофильные виды замещались морскими и наоборот), при этом менялась структура продукционного процесса. В 2000 – 2002 гг., несмотря на высокую численность, фитопланктон играл незначительную роль в общей первичной продукции, в то время как продукция кладофоровых матов была на 1 – 2 порядка выше. В 2004 – 2005 гг. кладофоровые маты отсутствовали в озере и первичная продукция, в основном, создавалась фитопланктоном. В 2006 - 2007 гг. вода в озере была прозрачной,...

Provedor de dados: 13
Autores: Мазлумян, С. А.; Болтачева, Н. А.; Колесникова, Е. А.
Приведены данные о развитии макрозообентоса на глубине 1 – 10 м  в бухте Лисьей (юго-восточное побережье Крыма, Черное море) в 1998 г. и проведено сравнение разнообразия бентоса в 1973 и 1998 гг. Отмечены существенные изменения в его таксономической структуре. Средняя численность и биомасса видов сообщества Chamelea gallina возросли примерно в 20 раз. При оценке видового разнообразия применены экологические индесы Шеннона, Симпсона, Пиелу, Маргалефа, Берджер-Паркер, а также метод сравнения к-доминантных кривых. Полученные результаты свидетельствуют об уменьшении разнообразия сообщества в 1998 г., по сравнению с 1973 г. Высказывается предположение о том, что происходящая в сообществе Chamelea gallina перестройка отчасти является результатом некоторого...

Autores: Шульман, Г. Е.; Токарев, Ю. Н.
На материалах проводимых в ИнБЮМ НАН Украины исследований рассмотрены многочисленные аспекты функционального биоразноообразия морской биоты – видовое, внутривидовое (популяционное), внутрипопуляционное (организменное), суборганизменное (тканевое, отчасти клеточное и молекулярное), а также его пространственные и временные аспекты. Показано, что направления эволюционного развития, определяющие биологический прогресс, обеспечиваются альтернативными метаболическими стратегиями, формирующими сложную гамму видового разнообразия. Проанализированы различные проявления функционального биоразноообразия, позволяющие понять: как сформировалась видовая, популяционная и внутрипопуляционная структура биоты, как осуществляется взаимодействие друг с другом компонентов...

Результаты многолетних исследований ИнБЮМ НАН Украины по биоразнообразию основных звеньев биоты Черного моря (на шельфе Крымского п-ова) позволяют считать, что пик деградации морской биоты, наибольшего обеднения ее видового богатства пришелся на период с конца 1980-х до середины 1990-х годов. После 1995 - 1998 гг. стали регистрироваться признаки оздоровления экосистем, которые затрагивают все звенья как пелагических, так и донных сообществ. Улучшение состояния биоты и увеличение числа встречаемых видов на крымском шельфе и даже в Севастопольских бухтах продолжаются до настоящего времени.

Seasonal variation in natural populations of Drosophila spp. (Diptera) in two woodlands in the State of São Paulo, Brazil
Provedor de dados: 76
Autores: Torres,Felipe Rafael; Madi-Ravazzi,Lilian.
The composition and the seasonality of the natural populations of Drosophila species in relation to the climatic variables temperature and rainfall were analyzed from September 1998 through October 1999 by monthly collections, in two woodlands in the Northwest of the State of São Paulo, Brazil. The diversity dominance component curves were inclined, reflecting low diversity and high dominance of few species. Among the 25 species recorded, Drosophila sturtevanti Duda, 1927 was the most frequent and abundant. On the opposite to data in literature, D. paranaensis Barros, 1950 abundance and frequency were greater than those from D. mercatorum Patterson &amp;amp; Wheeler, 1942. A positive correlation between abundance and rainfall was observed for D. nebulosa...

Assemblages of drosophilids (Diptera, Drosophilidae) in mangrove forests: community ecology and species diversity
Provedor de dados: 76
Autores: Schmitz,Hermes J.; Hofmann,Paulo R. P.; Valente,Vera L. S.
Brazilian fauna of drosophilids has been researched in various ecosystems, but those in mangrove forests remain overlooked in Brazil and elsewhere. The present study attempts to characterise the assemblages of drosophilids of this environment, based on 28 collections taken in three mangrove areas in Santa Catarina Island, southern Brazil. The three mangroves surveyed were different in their surroundings, which varied from highly urbanised areas to conservation areas with natural vegetation. Overall, 69 species were collected, and no remarkable difference was detected in species composition and abundances or in the richness, evenness and heterogeneity between sites. The species abundance distribution observed fitted to a theoretical lognormal distribution...

Comparative analysis of tidepool fish species composition on tropical coastal rocky reefs at State of Ceará, Brazil
Provedor de dados: 76
Autores: Cunha,Edna A.; Carvalho,Roberto A. A.; Monteiro-Neto,Cassiano; Moraes,Luiz Eduardo S.; Araújo,Maria Elisabeth.
This study compared tidepool fish assemblages within and among habitats at Iparana and Pecém beaches, State of Ceará, Northeast Brazil, using visual census techniques. A total of 8,914 fishes, representing 25 families and 43 species were recorded. The most abundant taxon was Sparisoma spp, followed by Haemulon parra (Desmarest, 1823), Acanthurus chirurgus (Bloch, 1787) and Abudefduf saxatilis (Linnaeus, 1758). Haemulidae was the most abundant family in number of individuals, followed by Scaridae, Acanthuridae and Pomacentridae. Within- and between- site differences in species assemblages probably reflected environmental discontinuities and more localized features, such as pool isolation episodes, or environmental complexity, both acting isolated or...

ABSTRACT Richness estimators (Jackknife 1, Bootstrap, Chao 1 and ACE) were used to relate zooplankton species richness with amount of water collected per sample and number of samples throughout the year for the limnetic region of Sapucai River compartment of Furnas reservoir, state of Minas Gerais, Brazil. Seven 100 L samples were collected in sequence using a motor pump, and seven 70 L samples were collected in sequence using a plankton net (68 μm mesh size) in vertical hauls, to totalize 450 L, in three stations of the reservoir. Twelve monthly samplings were carried out over a year. The assessment of richness was made by analyzing the asymptotic behavior of the estimator curves. The samplings reached the asymptote from 350 L of collection with trawls...

Environmental assessment in tropical streams by using abundance-biomass curves and W index in fish assemblages
Provedor de dados: 76
Autores: Mise,Fábio T.; Message,Hugo J.; Pagotto,João P. A.; Goulart,Erivelto.
ABSTRACT We investigated the fish fauna response to different environmental conditions of urban (three) and rural (seven) streams through biomass/abundance curves and W index of environmental stress. Negative values of W indicate some level of stress, while positive values suggest environments with lower stress. Dissolved oxygen, marginal erosion (both left and right margins), mesohabitat diversity, and percentage of canopy cover were measured to characterize the 10 streams analysed around Maringá city, Southern Brazil. Fish were sampled by electrofishing, then identified and weighed. Results showed negative values of W to the urban streams and positive to the rural. Urban streams showed a tendency to have assemblages of fish with lower biomass and greater...

Autores: Oliveira,Augusto; Callisto,Marcos.
The objective of this study was to evaluate benthic macroinvertebrate communities as bioindicators of water quality in five streams located in the "Reserva Particular do Patrimônio Natural" (RPPN) Mata Samuel de Paula and its surroundings, in the municipality of Nova Lima near the city of Belo Horizonte, Minas Gerais State, southeastern Brazil. This region has been strongly modified by human activities including mining and urbanization. Samples were collected in the field every three months between August 2004 and November 2005, totaling six samplings in the rainy and dry seasons. This assessment identified one area ecologically altered while the other sampling sites were found to be minimally disturbed systems, with well-preserved ecological conditions....

Provedor de dados: 76
Autores: Yamazaki,Lúcia; Vindica,Vanessa F.; Brescovit,Antonio D.; Marques,Marinez I.; Battirola,Leandro D.
ABSTRACT Spiders are generalist predators and present a high diversity of capturing and foraging, as well as considerable species richness in tropical habitats. Although, generally, not presenting specific relations to the host plant, they can be influenced by its phenology, structure and resource availability. So, this study analyzed temporal variation on the structure and composition of Araneae assemblage in Callisthene fasciculata (Spr.) Mart. (Vochysiaceae) canopies, in an area of monodominant vegetation, in the periods of high water, receding water, dry season and rising water in Pantanal of Mato Grosso, Brazil. The collection was performed on 24 individuals of C. fasciculata, six in each seasonal period, in 2010 and 2011, making use of canopy fogging...

Autores: QUEIROZ, J. A. L. de; MOCHIUTTI, S.
O açaizeiro (Euterpe oleracea, Mart.) é uma palmeira que ocorre nas florestas de várzea do estuário amazônico e em áreas úmidas de terra-firme, chamadas de grotas. Nas várzeas do estuário amazônico, os açaizeiros apresentam grandes densidades e trouçeiras com elevado número de estirpes, convivendo em harmonia com as demais espécies que ocorrem na floresta. Neste ambiente a produção de frutos é boa e ocorre naturalmente durante o ando todo, sendo que em alguns meses há produção de muitos frutos e em outros meses produção de poucos frutos, o que resulta em grande oscilação em seu preço.

A Amazônia na economia natural do conhecimento.
Provedor de dados: 14
Autores: LOPES, M. A.
A Amazônia é, de longe, o melhor estudo de caso para inserção do Brasil na economia natural do conhecimento. Primeiro, porque precisamos estar mais preparados a argumentar de forma mais inteligente e assertiva com aqueles que insistem que o Brasil deve se responsabilizar sozinho, e de graça, por uma enorme fatia da proteção ambiental do planeta. Segundo, porque já vemos emergir no mundo uma nova economia de base biológica, em segmentos vitais como a agricultura, a saúde, e as indústrias química, de materiais e de energia. E a biodiversidade, a maior riqueza da Amazônia , é matéria-prima essencial para o futuro dessa bioeconomia.

O monitoramento de mamíferos em fazendas é relevante tanto para a conservação da biodiversidade quanto para a geração de ações de sustentabilidade em áreas de fruticultura. Por exemplo, mamíferos carnívoros predando roedores, podem atuar no controle de pragas agrícolas. Por isso determinar quais espécies são encontradas em fazendas e em áreas de vegetação natural permite identificar as espécies e caracterizar as comunidades. Atualmente, estamos enfrentando uma crise ambiental em precedentes, a sexta extinção em massa da biodiversidade. Estima-se que a perda de espécies em um curto período de tempo equivale a processos de extinção ocorridos há milhões de anos, onde se propõe um novo período geológico: o Antropoceno, a era da humanidade. Grande parte dessas...

Autores: CAMARGO, N. F. de; AGUIAR, L. M. de S.
ABSTRACT: The Cerrado is one of the richest and most threatened biome in the world and its ecosystem Seasonally dry forest is the one that suffers most antropic pressure. It's important that conservation of The Paranã River Valley increases because it presents a greater amount of dry forest in the Cerrado. According to data compilation from literature, 120 mammal species, 179 bird species, 109 reptile species and 44 amphibian species were registered in Paranã-Pirineus corridor counties. Few studies were made about this region fauna and it's hard to estimate the precise diversity at Paranã River Valley. However, the species richness presented here shows how important this ecosystem is for the fauna´s maintenance. For that, this data compilation about...

Charting new ?sustainable agricultural pathways? in Brazil.
Provedor de dados: 14
Autores: LOPES, M. A.
Brazil is a large country spanning several climatic zones. Its bountiful supplies of fresh water, abundant solar radiation and rich biodiversity have enabled it to become one of the world?s largest producers of food, feed, fibers and renewable fuels. But it is not these natural endowments alone that put Brazil decisively on this pathway: it is also the country?s advanced capacity in technology development, put to use over decades. Now, that same capacity is being directed towards a sustainable future. Charting new ?sustainable agricultural pathways? will revitalize Brazil?s landscape and serve as a model for countries facing similar challenges across the planet?s tropical belt.

Efeitos da fragmentação sobre a diversidade de saturniidae (Lepidoptera) em isolados naturais e antrópicos de Cerrado.
Provedor de dados: 14
Autores: CAMARGO, A. J. A. de; SCHMIDT, K.
Uma das questões mais importantes sobre a perda da diversidade biológica no Cerrado é o processo recente e acelerado de fragmentação. O objetivo deste trabalho foi investigar os efeitos da fragmentação de hábitats sobre a diversidade taxonômica de Saturniidae em isolados naturais e antrópicos no Cerrado. Os trabalhos de campo foram conduzidos em dois conjuntos de Cerrado, cada um com três fragmentos. O primeiro, ao Sul de Rondônia (Vilhena e Pimenta Bueno com fragmentos naturais), e o segundo, em três áreas em Catalão, GO (fragmentos antrópicos). As coletas foram realizadas com armadilhas luminosas contendo lâmpadas mistas de 250 watts. Foram registrados 232 indivíduos de 33 espécies nos fragmentos naturais e 602 indivíduos de 40 espécies nos antrópicos....

Autores: Gooday, Andrew J.; Holzmann, Maria; Caulle, Clemence; Goineau, Aurelie; Jones, Daniel Ob; Kamenskaya, Olga; Simon-lledo, Erik; Weber, Alexandra A. -t.; Pawlowski, Jan.
We describe Aschemonella monile Gooday and Holzmann sp. nov. from the Clarion-Clipperton Zone (CCZ, abyssal eastern equatorial Pacific), a region characterized by commercially significant concentrations of polymetallic nodules. The new species is the most abundant xenophyophore (giant agglutinated foraminifera) in our main sampling area (12-14 degrees N; 116 degrees 30'-117 degrees 26'W). Additional specimens originate from the central CCZ, and from a third area, similar to 900 km NW of the main area, where A. monile numerically dominates the megabenthos in photographic surveys of the seafloor (average densities 1.54 individuals/m(2); peak densities &gt; 3 individuals/m(2)). Aschemonella monile is much larger (&gt;= 7 cm in length) than previously...

Peripatric speciation drives diversification and distributional pattern of reef Hermit Crabs (Decapoda: Diogenidae: Calcinus)
Provedor de dados: 5
Autores: Malay, Maria Celia (machel) D.; Paulay, Gustav.
The diversity on coral reefs has long captivated observers. We examine the mechanisms of speciation, role of ecology in speciation, and patterns of species distribution in a typical reef-associated clade-the diverse and colorful Calcinus hermit crabs-to address the origin of tropical marine diversity. We sequenced COI, 16S, and H3 gene regions for similar to 90% of 56 putative species, including nine undescribed, "cryptic" taxa, and mapped their distributions. Speciation in Calcinus is largely peripatric at remote locations. Allopatric species pairs are younger than sympatric ones, and molecular clock analyses suggest that &gt; 2 million years are needed for secondary sympatry. Substantial niche conservatism is evident within clades, as well as a few major...

Fishing destabilizes the biomass flow in the marine size spectrum
Provedor de dados: 5
Autores: Rochet, Marie-joelle; Benoit, E.
Fishing impacts on marine food webs are predicted by simulations of a size spectrum community model. In this model, predation is determined by predator and prey size and abundance, and drives predator growth and prey mortality. Fishing amplifies temporal oscillations in the biomass flow. Oscillations appear at lower fishing intensity and have wider amplitude when fishing is selective (removes a narrow size range) and/or when large fish are targeted, than when fishing is more balanced (catching a larger size range) or when small fish are targeted. A novel index of size diversity is developed, and is shown to be sensitive to both fishing intensity and selectivity. To avoid unstable food web dynamics with potential harmful consequences for fisheries, limiting...

Fishing effects on the diversity dynamics of demersal fish communities. Comparative analysis of the role of the interactions between specices in the Bay of Biscay and in the Gulf of Lion (France).
Provedor de dados: 5
Autores: Blanchard, Fabian.
This work deals with the fishing effects on the diversity dynamics of demersal fish communities, focusing on the biotic interactions. Multispecies indices were used in order to characterise the demersal fish community dynamics of the Bay of Biscay and of the Gulf of Lions. These are the diversity indices, the temporal variability of the total biomass and of the slope of the number size spectra and the slope of the species-area curves (spatial segregation). The data were provided by yearly bottom trawl surveys EVHOE, CHALIST and MEDITS carried out in these two areas since 1983 by IFREMER for stock assessment. The differences between areas are related to a fishing index (mean value of the annual landings of demersal fish per surface area). Other areas are...

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...

Efforts to conserve biodiversity comprise a patchwork of international goals, national-level plans, and local interventions that, overall, are failing. We discuss the potential utility of applying the mitigation hierarchy, widely used during economic development activities, to all negative human impacts on biodiversity. Evaluating all biodiversity losses and gains through the mitigation hierarchy could help prioritize consideration of conservation goals and drive the empirical evaluation of conservation investments through the explicit consideration of counterfactual trends and ecosystem dynamics across scales. We explore the challenges in using this framework to achieve global conservation goals, including operationalization and monitoring and compliance,...

Rebuilding fish communities: the ghost of fisheries past and the virtue of patience
Provedor de dados: 5
Autores: Collie, Jeremy; Rochet, Marie-joelle; Bell, Richard.
The ecosystem approach to management requires the status of individual species to be considered in a community context. We conducted a comparative ecosystem analysis of the Georges Bank and North Sea fish communities to determine the extent to which biological diversity is restored when fishing pressure is reduced. First, fishing mortality estimates were combined to quantify the community-level intensity and selectivity of fishing pressure. Second, standardized bottom-trawl survey data were used to investigate the temporal trends in community metrics. Third, a size-based, multispecies model (LeMans) was simulated to test the response of community metrics to both hypothetical and observed changes in fishing pressure in the two communities. These temperate...

Les observations de poissons tropicaux et le réchauffement des eaux dans l’Atlantique européen
Provedor de dados: 5
Autores: Quero, Jean-claude; Du Buit, Marie-henriette; Vayne, Jean-jacques.
A recapitulation of the records of tropical fishes from European Atlantic waters shows that 67.6 % were fishes caught from the upper slope, between approximately 200 and 600 m; 19.8 % were fishes caught from the continental shelf; and 13.5 % were specimens caught from the middle slope, between 700 and 1 300 m. Since 1963, the upper slope species have made regular northward range extensions off of south Portugal to north-western Ireland (about 55 degrees 30' N), more and less rapidly, about 30 years for Cyttopsis roseus and only 6 years for Sphoeroides pachygaster. The continental shelf species, observed from 1969 but mostly from 1981, have a northward range to south-eastern Ireland (about 52 degrees N), but 65.2 % of them have been caught off the south of...

Planktonic populations were sampled over a 4 week period in the NW Mediterranean, at a site subject to little vertical advection during the Dynaproc 2 cruise in 2004. The characteristics of the phytoplankton, the tintinnid community and the zooplankton have recently been described in detail. Based on these studies, we compared the characteristics of 3 well-circumscribed assemblages of different trophic levels: Ceratium of the phytoplankton, herbivorous tintinnids of the microzooplankton, and large (&gt; 500 mu m) omnivorous and carnivorous copepods of the metazoan zooplankton. In all three groups, diversity as H' or species richness, was less variable than concentration of organisms. Plotting time against species accumulation, the curves approached plateau...

Reef-building species are recognized as having an important ecological role and as generally enhancing the diversity of benthic organisms in marine habitats. However, although these ecosystem engineers have a facilitating role for some species, they may exclude or compete with others. The honeycomb worm Sabellaria alveolata (Linnaeus, 1767) is an important foundation species, commonly found from northwest Ireland to northern Mauritania, whose reef structures increase the physical complexity of the marine benthos, supporting high levels of biodiversity. Local patterns and regional differences in taxonomic and functional diversity were examined in honeycomb worm reefs from 10 sites along the northeastern Atlantic to explore variation in diversity across...

Autores: Moritz, Charlotte; Levesque, Melanie; Gravel, Dominique; Vaz, Sandrine; Archambault, Diane; Archambault, Philippe.
Correlative habitat models using relationships between marine organisms and their surrounding environment can be used to predict species distribution, and the results can assist management of human activities sharing the marine space (e.g. fisheries, MPAs, tourism). Here, epi-benthic megafauna was sampled at 755 stations in the Lower Estuary and Northern Gulf of St. Lawrence (EGSL) each summer between 2006 and 2009. We combined various types of multivariate analyses to 1) describe the structure and spatial distribution of benthic communities, 2) analyse the relationship between these communities and environmental parameters, and subsequently 3) build a community distribution model to predict the spatial distribution of the communities, creating community...

Soil Health Changes Over a 25-Year Chronosequence From Forest to Plantations in Rubber Tree (Hevea brasiliensis) Landscapes in Southern Côte d'Ivoire: Do Earthworms Play a Role?
Provedor de dados: 5
Autores: Tondoh, Jérôme E.; Dimobe, Kangbéni; Guéi, Arnauth M.; Adahe, Léontine; Baidai, Yannick; N'Dri, Julien K.; Forkuor, Gerald.
The agro-ecological drawbacks of the spread of rubber tree plantations in Côte d'Ivoire since the 1990's are obvious even though they have not been properly investigated. They consist of biodiversity loss, land degradation and food insecurity, which have extended into the existing cocoa-led degraded areas whose rehabilitation have unfortunately not started. This situation increases not only the threat on soil health status but also undermines the capability of soils to deliver ecosystem services that are key to sustainable agricultural production. The current study took advantage of a chronosequence in rubber tree landscapes to assess soil health deterioration in general and possibly earthworm-mediated role in soil health changes. The hypothesis...

Coastal populations of maritime countries in eastern Africa rely on fish as a primary source of protein, but baseline information on the abundance of fish communities on these coastlines is often lacking. We used baited remote underwater video stations to compare the abundance and diversity of reef fishes targeted by fishing at two sites in southern Mozambique, one at Lighthouse Reef within the Bazaruto Archipelago National Park and the other to the south at San Sebastian Reef on the San Sebastian Peninsula. Fish that are known targets of fisheries (mostly small-scale and artisanal) had an abundance that was almost three-times greater at San Sebastian Reef (80.22 ind. h–1 [SE 18.00]) than at Lighthouse Reef (29.70 ind. h–1 [SE 8.91]). Similarly, there was...

Scenario analyses have been used in multiple science-policy assessments to better understand complex plausible futures. Scenario archetype approaches are based on the fact that many future scenarios have similar underlying storylines, assumptions, and trends in drivers of change, which allows for grouping of scenarios into typologies, or archetypes, facilitating comparisons between a large range of studies. The use of scenario archetypes in environmental assessments foregrounds important policy questions and can be used to codesign interventions tackling future sustainability issues. Recently, scenario archetypes were used in four regional assessments and one ongoing global assessment within the Intergovernmental Science-Policy Platform for Biodiversity...

Meiofauna assemblages of the Condor Seamount (North-East Atlantic Ocean) and adjacent deep-sea sediments
Provedor de dados: 5
Autores: Zeppilli, Daniela; Bongiorni, Lucia; Cattaneo, Antonio; Danovaro, Roberto; Santos, R.
Seamounts are currently considered hotspots of biodiversity and biomass for macro- and megabenthic taxa, but knowledge of meiofauna is still limited. Studies have revealed the existence of highly diverse meiofauna assemblages; however most data are mainly qualitative or focused only on specific groups, thus preventing comparisons among seamounts and with other deep-sea areas. This study, conducted on Condor Seamount (Azores, North-East Atlantic Ocean), describes variation in abundance, biomass, community structure and biodiversity of benthic meiofauna from five sites located on the Condor Seamount: and one site away from the seamount. While the summit of the seamount hosted the highest alpha biodiversity, the flanks and the bases showed a rich meiofauna...

Impact of climatic and anthropogenic changes on living resources in the Bay of Biscaye
Provedor de dados: 5
Autores: Goulletquer, Philippe.
Fisheries and aquaculture are of major importance to the coastal communities throughout the Bay of Biscaye. Almost half of French fishermen rely on catches from the Bay which achieve and estimated first sale value of more than €525m annually. Moreover, emblematic species such as eels have an additional economic as weil as social value for coastal communities. Similarly, the main French shellfish rearing areas are located within the Bay of Biscaye. They contribute predominantly to the yearly spat (mussel &amp; oyster) recruitment, used to sustain the entire French shellfish industry. These activities have a direct impact on ecosystem functioning and biodiversity. Meanwhile, drastic environmental changes have been reported over the last 30 years, including a...

Despite bycatch of elasmobranch (sharks and rays) being a major concern in most fisheries worldwide, there is a lack of knowledge on their spatio-temporal species distribution, biology (life stage and sex-ratios), as well as their at-haulback mortality rate. Observer data from the French and Spanish tropical purse-seine tuna fisheries operating in the Eastern Atlantic and Western Indian Oceans between 2005 and 2017 were analysed to investigate elasmobranch bycatch. Data included 24 elasmobranchs species and distribution patterns of catch per unit of effort (CPUE) by species and sex-ratio were found to vary with life stages, areas, seasons and fishing modes. In general, higher catches were found in FAD-associated sets (&gt;40%) than free tuna school sets...

The great variety of geological and hydrological conditions in the deep sea generates many different habitats. Some are only recently explored, although their true extent and geographical coverage are still not fully established. Both continental margins and mid-oceanic seafloors are much more complex ecologically, geologically, chemically and hydrodynamically than originally thought. As a result, fundamental patterns of species distribution first observed and explained in the context of relatively monotonous slopes and abyssal plains must now be re-evaluated in the light of this newly recognized habitat heterogeneity. Based on a global database of nematode genus composition, collected as part of the Census of Marine Life, we show that macrohabitat...

Bioindicators assess the mangroves ecological state according to the types of pressures but they differ with the ecosystem’s specificities. We investigated benthic meiofauna diversity and structure within the low human-impacted mangroves in French Guiana (South America) in response to sediment variables with various distances to the main city. Contaminant’s concentrations differed among the stations, but they remained below toxicity guidelines. Meiofauna structure (Foraminifera, Kinorhyncha, Nematoda) however varied accordingly. Nematode’s identification brought details on the sediment’s quality. The opportunistic genus Paraethmolaimus (Jensen, 1994) strongly correlated to the higher concentrations of Hg, Pb. Anoxic sediments were marked by organic...

Environmental DNA (eDNA) analysis is a revolutionary method to monitor marine biodiversity from animal DNA traces. Examining the capacity of eDNA to provide accurate biodiversity measures in species‐rich ecosystems such as coral reefs is a prerequisite for their application in long‐term monitoring. Here, we surveyed two Colombian tropical marine reefs, the island of Providencia and Gayraca Bay near Santa Marta, using eDNA and underwater visual census (UVC) methods. We collected a large quantity of surface water (30 L per filter) above the reefs and applied a metabarcoding protocol using three different primer sets targeting the 12S mitochondrial DNA, which are specific to the vertebrates Actinopterygii and Elasmobranchii. By assigning eDNA sequences to...

Ability of taxonomic diversity indices to discriminate coastal lagoon environments based on macrophyte communities
Provedor de dados: 5
Autores: Mouillot, David; Gaillard, Sylvain; Aliaume, Catherine; Verlaque, Marc; Belsher, Thomas; Troussellier, Marc; Chi, Thang.
Lagoons are highly productive areas representing more than 50% of the coastline area in Languedoc-Roussillon (South of France, Mediterranean sea). These lagoons are very different in their environmental conditions, human influences, eutrophication levels and aquaculture intensity. Based on macrophyte communities associated with soft substrates, two indices of taxonomic diversity (the "average taxonomic distinctness" (Delta(+)) and the "variation in taxonomic distinctness" (Lambda(+))) were used to discriminate four of these lagoons (Thau, Salse-Leucate, Bages-Sigean and Mauguio). Bages-Sigean presented a significant higher average taxonomic distinctness (p &lt; 0.05) and Salse-Leucate had a significant higher variation in taxonomic distinctness (p &lt;...

Conservation of marine habitats under multiple human uses. Methods, objectives and constraints to optimize a Marine Protected Areas network in the eastern English Channel
Provedor de dados: 5
Autores: Delavenne, Juliette.
The eastern English Channel is a significant economic area that supports a number of human-based activities, such as tourism and recreational activities, international ports and shipping, and the extraction of both living and mineral resources. In addition, the region supports a number of important marine biological features and large habitat diversity. Marine Protected Areas (MPAs) are increasingly used as a management tool to foster a sustainable exploitation of marine resources in an ecosystem based management framework. All European countries have a legal obligation to develop MPA networks in their national waters. However, there has to date been only limited attempts to coordinate the design and positioning of such networks at an international level...

Meiofauna Community in Soft Sediments at TAG and Snake Pit Hydrothermal Vent Fields
Provedor de dados: 5
Autores: Spedicato, Adriana; Sánchez, Nuria; Pastor, Lucie; Menot, Lenaick; Zeppilli, Daniela.
The risk assessment of seafloor massive sulfide (SMS) mining on meiobenthic organisms, specifically on soft-sediment meiofauna, is impeded by a lack of knowledge on the biology and ecology of these communities. In this study, we investigated sediment samples taken in proximity of active vents at Trans-Atlantic Geotraverse (TAG) and Snake Pit, two hydrothermal vent fields of the Mid-Atlantic Ridge, in order to explore metazoan meiofauna, particularly nematode community, and its relation to organic carbon, total nitrogen, total sulfur, and dissolved oxygen. Organic carbon and nitrogen contents were low at both sites. High concentrations of total sulfur and low oxygen penetration were found at Snake Pit compared to TAG. Snake Pit showed approximately four...

Autores: Dubois, Stanislas; Derian, Francois; Caisey, Xavier; Rigolet, Carinne; Caprais, Jean-claude; Thiebaut, Eric.
We used existing bathymetric data to study the macrofauna of a geophysical pockmark field restricted to a benthic habitat engineered by the tubiculous amphipod Haploops nirae in South Brittany (France). Stations inside and outside pockmarks of different morphometric characteristics (location, size, depression depth) were sampled for macrofauna and environmental parameters (sediment characteristics, organic matter, chl a, hydrogen sulfide and methane concentrations). Diversity indices showed higher species richness inside pockmarks, especially for species with medium to high abundances. Most sediment cores showed low methane but high hydrogen sulfide concentrations. We hypothesised that after eruption, the remaining residual methane from pockmark sediments...

Trawling activities are considered to be one of the main sources of disturbance to the seabed worldwide. We aimed to disentangle the dominance of environmental variations and trawling intensity in order to explain the distribution of diversity patterns over 152 sampling sites in the French trawl fishing-ground, the Grande Vasière. Using a towed underwater video device, we identified 39 taxa to the finest taxonomic level possible, which were clustered according to their vulnerability to trawling disturbance based on functional traits. Using generalized linear models, we investigated whether the density distribution of each vulnerability group was sensitive to trawling intensity and habitat characteristics. Our analyses revealed a structuring effect of depth...

Contextual data collected concurrently with molecular samples are critical to the use of metagenomics in the fields of marine biodiversity, bioinformatics and biotechnology. We present here Marine Microbial Biodiversity, Bioinformatics and Biotechnology (M2B3) standards for "Reporting" and "Serving" data. The M2B3 Reporting Standard (1) describes minimal mandatory and recommended contextual information for a marine microbial sample obtained in the epipelagic zone, (2) includes meaningful information for researchers in the oceanographic, biodiversity and molecular disciplines, and (3) can easily be adopted by any marine laboratory with minimum sampling resources. The M2B3 Service Standard defines a software interface through which these data can be...

Terrestrial and marine biodiversity provides the basis for both ecosystems functioning and numerous commodities or services that underpin human well-being. From several decades, alarming trends have been reported worldwide for both biodiversity and ecosystem services. Therefore the sustainable management of biodiversity requires a double viewpoint balancing ecological conservation with the welfare of human societies. Understanding the underlying trade-offs, synergies and interactions imposes the development of interdisciplinary researches and methods. In that respect, bio-economic or ecological economic modeling is likely to play a major role. The present paper intends to elicit the key features, strengths and challenges of bio-economic approaches...

Reconciling food security, economic development and biodiversity conservation is a key challenge, especially in the face of the demographic transition characterizing many countries in the world. Fisheries and marine ecosystems constitute a difficult application of this bio-economic challenge. Many experts and scientists advocate an ecosystem approach to manage marine socio-ecosystems for their sustainability and resilience. However, the ways by which to operationalize ecosystem-based fisheries management (EBFM) remain poorly specified. We propose a specific methodological framework-viability modelling-to do so. We show how viability modelling can be applied using four contrasted case-studies: two small-scale fisheries in South America and Pacific and two...

Assessing spatial and temporal variability of phytoplankton communities' composition in the Iroise Sea ecosystem (Brittany, France): A 3D modeling approach: Part 2: Linking summer mesoscale distribution of phenotypic diversity to hydrodynamism
Provedor de dados: 5
Autores: Cadier, Mathilde; Sourisseau, Marc; Gorgues, Thomas; Edwards, Christopher A.; Memery, Laurent.
Tidal front ecosystems are especially dynamic environments usually characterized by high phytoplankton biomass and high primary production. However, the description of functional microbial diversity occurring in these regions remains only partially documented. In this article, we use a numerical model, simulating a large number of phytoplankton phenotypes to explore the three-dimensional spatial patterns of phytoplankton abundance and diversity in the Iroise Sea (western Brittany). Our results suggest that, in boreal summer, a seasonally marked tidal front shapes the phytoplankton species richness. A diversity maximum is found in the surface mixed layer located slightly west of the tidal front (i.e., not strictly co-localized with high biomass...

Studies on the distribution of scleractinian corals in the Bay of Biscay were relatively numerous during the nineteenth and the first half of the twentieth century. Yet, recent reports are scattered, sometimes unpublished, and therefore knowledge about the current coral occurrence in the area is limited. This study aims at compiling the available historical and more recently collected information on the occurrence of scleractinian corals in the Bay of Biscay. Data from two recent cruises are included and compared with previous explored coral sites from as early as 1830 up to 1995. A database of 347 records including 34 described species of scleractinians highlights that the slope of the Bay of Biscay is an important habitat for scleractinians. This could...

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...

Macrofauna are an abundant and diverse component of abyssal benthic communities and are likely to be heavily impacted by polymetallic nodule mining in the Clarion-Clipperton Zone (CCZ). In 2012, the International Seabed Authority (ISA) used available benthic biodiversity data and environmental proxies to establish nine no-mining areas, called Areas of Particular Environmental Interest (APEIs) in the CCZ. The APEIs were intended as a representative system of protected areas to safeguard biodiversity and ecosystem function across the region from mining impacts. Since 2012, a number of research programs have collected additional ecological baseline data from the CCZ. We assemble and analyze macrofaunal biodiversity data sets from eight studies, focusing on...

Deep-sea areas characterized by the presence of polymetallic nodules are getting increased attention due to their potential commercial and strategic interest for metals such as nickel, copper and cobalt. The polymetallic nodules occur in areas beyond national jurisdiction, regulated by the International Seabed Authority (ISA). Under exploration contracts, contractors have the obligation to determine the environmental baseline in the exploration areas. Despite a large number of scientific cruises to the central east Pacific Ocean, few published data on the macrofaunal biodiversity and community structure are available for the abyssal fields of the Clarion-Clipperton Fracture Zone (CCFZ).

The main objective of this pilot study, conducted in June 2015 in the Can Gio Mangrove Biosphere Reserve (Can Gio MBR, Viet Nam), was to develop an interdisciplinary approach to assess some key services provided by reforested mangroves subject to external pressures and varying management policies. We focused on the abundance of viruses, bacteria, endo-and epi-and macrofauna and the diversity of crabs in the mangrove and the exploitation of its resources. The main social finding was that the local inhabitants are aware of the levels of protection of the different zones within the Can Gio MBR and respect them. The core and the buffer zones seem to present a similar ecological status. Genotyping showed a low level of crab diversity although there were many...

Whale falls are important environments contributing to biodiversity, connectivity and evolutionary novelty in deep-sea ecosystem. Notwithstanding, most of this knowledge is based in studies from NE Pacific basin. Interestingly, the only known natural whale fall on the SW Atlantic has faunal composition affinities with carcasses from other deep-ocean basins. In this carcass, annelid worms belonging to Hesionidae are abundant and species-rich, and include some shared species with NE Pacific Ocean. Here we evaluate the diversity of Hesionidae on the SW Atlantic using new information of implanted whale bones and explore whether some species have interbasin distribution or if they represent cryptic species in different basins. We described, using morphological...

Biodiversity–Ecosystem Functioning (BEF) approach to further understanding aquaculture–environment interactions with application to bivalve culture and benthic ecosystems
Provedor de dados: 5
Autores: Lacoste, Elise; Mckindsey, Christopher W.; Archambault, Philippe.
Coastal benthic ecosystems may be impacted by numerous human activities, including aquaculture, which continues to expand rapidly. Indeed, today aquaculture worldwide provides more biomass for human consumption than do wild fisheries. This rapid development raises questions about the interactions the practice has with the surrounding environment. In order to design strategies of sustainable ecosystem exploitation and marine spatial planning, a better understanding of coastal ecosystem functioning is needed so that tools to quantify impacts of human activities, including aquaculture, may be developed. To achieve this goal, some possible directions proposed are integrated studies leading to new concepts, model development based on these concepts and...

Autores: Levrel, Harold; Kerbiriou, Christian; Couvet, Denis; Weber, Jacques.
Sustainability is said to be the science of integration, be it integration of scale, discipline or of stakeholders' interests. One way to integrate such diverse elements is to develop sustainable development indicators. Numerous national and international organizations have attempted to develop such indicators, among which interaction indicators are of critical importance because they enable us to link up human activities, ecological dynamics, and social goals. Among the various ways to develop such indicators, the most common ones are the pressure-state-response (PSR) indicators, as well as others coming from this framework. With realistic methodology one shall observe how PSR indicators might appear as an operational tool to face rapid social and...

Numerical structure and the organisation of food webs within macrozoobenthic communities has been assessed in the European waters (Svalbard, Barents Sea, Baltic Sea, North Sea, Atlantic Ocean and the Mediterranean Sea) to address the interactions between biodiversity and ecosystem functioning. Abundance and classical species diversity indices (S, H', J) of macrofaunal communities were related to principal attributes of food webs (relative trophic level and food chain length, FCL) that were determined from carbon and nitrogen stable isotope values. Structure of marine macrobenthos varies substantially at a geographical scale; total abundance ranges from 63 ind. m(-2) to 34,517 ind. m(-2), species richness varies from 3 to 166 and the Shannon-Weaver...

Cold-water coral ecosystems have been identified as vulnerable, but quantitative data on their conservation status is very limited. The Marine Strategy Framework Directive (MSFD) is the tool implemented by the European Union’s Integrated Maritime Policy to achieve Good Environmental Status (GES) of marine waters by 2020. In this context, the aim of this study was to evaluate the Ecological Status of benthic habitats in Cassidaigne canyon, focusing in particular on cold-water coral habitats dominated by Madrepora oculata. Data were collected during the Videocor1 cruise (2017). Videos and photos collected during eight dives of the H-ROV Ariane were used to reconstruct, in 3-dimensions, the areas where cnidarians have settled in the canyon. A total of 33 3D...

Ocean Sampling Day was initiated by the EU-funded Micro B3 (Marine Microbial Biodiversity, Bioinformatics, Biotechnology) project to obtain a snapshot of the marine microbial biodiversity and function of the world's oceans. It is a simultaneous global mega-sequencing campaign aiming to generate the largest standardized microbial data set in a single day. This will be achievable only through the coordinated efforts of an Ocean Sampling Day Consortium, supportive partnerships and networks between sites. This commentary outlines the establishment, function and aims of the Consortium and describes our vision for a sustainable study of marine microbial communities and their embedded functional traits.

Dynamics of benthic copepods and other meiofauna in the benthic boundary layer of the deep NW Mediterranean Sea
Provedor de dados: 5
Autores: Guidi-guilvard, L. D.; Thistle, D.; Khripounoff, Alexis; Gasparini, S.
A continuous high-resolution time-series survey of the hyperbenthic community and local environmental conditions was conducted in the benthic boundary layer (BBL) of the DYFAMED-BENTHOS station (43 degrees 24.61'N, 7 degrees 51.67'E at 2347 in depth in the NW Mediterranean) between January 1996 and April 1998 using bottom-moored sediment traps and a current meter. Sediment traps were set 4 m above the bottom. Hyperbenthos was collected as 'swimmers', i.e. those organisms that are alive when they enter the traps but are not part of the particle flux. Identification of these organisms showed that similar to 90%, were meiobenthic, Copepods dominated and comprised on average 75%, of total swimmers. They were followed by nauplii (12%), annelids (7.8%),...

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...

Combining the Biocean database for deep-sea benthic data with the online Ocean Biogeographic Information System
Provedor de dados: 5
Autores: Fabri, Marie-claire; Galeron, Joelle; Larour, Michel; Maudire, Gilbert.
The Biocean database was designed to collate the extremely large volume of data collected from different deep-sea ecosystem studies conducted by Ifremer's department of 'Environnement Profond' (Deep-Sea Environment). This database comes in a 6-application package: 2 of them are used on research vessels to collect operational data, whereas the others are used to link with a core database back on land. The latter are used to: (1) manage taxonomic nomenclature, (2) monitor the identification of faunal collections, (3) fill in chemical analyses results or measurement data files and (4) add or extract data from the database. Biocean was designed to facilitate ecosystem studies in the deep sea. It represents an important new resource for deep-sea ecologists and...

To account for progress towards conservation targets, monitoring systems should capture not only information on biodiversity but also knowledge on the dynamics of ecological processes and the related effects on human well-being. Protected areas represent complex social-ecological systems with strong human-nature interactions. They are able to provide relevant information about how global and local scale drivers (e.g., climate change, land use change) impact biodiversity and ecosystem services. Here we develop a framework that uses an ecosystem-focused approach to support managers in identifying essential variables in an integrated and scalable approach. We advocate that this approach can complement current essential variable developments, by allowing...

Coût d’opportunité versus coût du maintien des potentialités écologiques : deux indicateurs économiques pour mesurer les coûts de l’érosion de la biodiversité
Provedor de dados: 5
Autores: Levrel, Harold; Hay, Julien; Bas, Adeline; Gastineau, Pascal; Pioch, Sylvain.
The cost of ecosystem services degradation is a major topic as underlined by the TEEB program (The Economics of Ecosystems and Biodiversity), which proposed an assessment of the costs of policy inaction in the field of biodiversity conservation. In the same vein, the report of the French Centre for Strategic Analysis on the Economic Approach to Biodiversity and Ecosystem Services turns its attention to the value of ecosystem services, suggesting some elements that could help measure the cost of biodiversity degradation. There is however some confusion regarding the notion of cost. Thus, in the case of TEEB the proposed cost assessment translates into monetary terms the loss of potential profits from ecological services. Yet, another way of assessing these...

The high species richness, coupled with high proportion of endemism, makes the Mediterranean one of the world’s ‘biodiversity hotspots’. However, the continuous increase in fisheries in the last few decades has led to the overexploitation of their main commercial stocks. Using fishery-independent data collected under the framework of the MEDITS trawl surveys carried out over the last 20 years, we study the demersal fish diversity pattern in the Mediterranean at a large spatial and temporal scale to determine whether it is being affected by the general fishing overexploitation of the demersal resources. The detected diversity trends are compared with the spatio-temporal variation in bottom trawl fishing effort in the Mediterranean. Our results show a...

Despite representing one of the largest biomes on earth, biodiversity of the deep seafloor is still poorly known. Environmental DNA metabarcoding offers prospects for fast inventories and surveys, yet requires standardized sampling approaches and careful choice of environmental substrate. Here, we aimed to optimize the genetic assessment of prokaryote (16S), protistan (18S V4), and metazoan (18S V1–V2, COI) communities, by evaluating sampling strategies for sediment and aboveground water, deployed simultaneously at one deep-sea site. For sediment, while size-class sorting through sieving had no significant effect on total detected alpha diversity and resolved similar taxonomic compositions at the phylum level for all markers studied, it effectively...

Plankton are the base of marine food webs, essential to sustaining fisheries and other marine life. Continuous Plankton Recorders (CPRs) have sampled plankton for decades in both hemispheres and several regional seas. CPR research has been integral to advancing understanding of plankton dynamics and informing policy and management decisions. We describe how the CPR can contribute to global plankton diversity monitoring, being cost-effective over large scales and providing taxonomically resolved data. At OceanObs09 an integrated network of regional CPR surveys was envisaged and in 2011 the existing surveys formed the Global Alliance of CPR Surveys (GACS). GAGS first focused on strengthening the dataset by identifying and documenting CPR best practices,...

Ecoviability for small-scale fisheries in the context of food security constraints
Provedor de dados: 5
Autores: Cisse, Abdoul; Doyen, L.; Blanchard, Fabian; Bene, Christophe; Pereau, J. -c.
This paper applies a stochastic viability approach to a tropical small-scale fishery, offering a theoretical and empirical example of ecosystem-based fishery management approach that accounts for food security. The model integrates multi-species, multi-fleet and uncertainty as well as profitability, food production, and demographic growth. It is calibrated over the period 2006–2010 using monthly catch and effort data from the French Guiana's coastal fishery, involving thirteen species and four fleets. Using projections at the horizon 2040, different management strategies and scenarios are compared from a viability viewpoint, thus accounting for biodiversity preservation, fleet profitability and food security. The analysis shows that under certain...

Questions How does plant community diversity influence variation in plant biomass? There are two competing hypotheses: the ‘biomass‐ratio hypothesis’, where biomass is influenced by the abundance and traits of the most dominant species, and the ‘diversity hypothesis’, where the diversity of organisms influences biomass through mechanisms such as niche complementarity. However, no studies have tested which one of these two hypotheses better explains the variation in plant biomass in the forest understorey. Location Temperate deciduous forests in Northern France. Methods For the forest understorey, we assessed species diversity and biomass as well as soil and light conditions in 133 forest plots of 100m² each. Using mixed‐effect models and after controlling...

Autores: Quero, Jean-claude; Dubuit, Marie-henriette; Vayne, Jean-jacques.
A recapitulation of the records of tropical fishes from European Atlantic waters shows that 67.6 % were fishes caught from the upper slope, between approximately 200 and 600 m; 19.8 % were fishes caught from the continental shelf; and 13.5 % were specimens caught from the middle slope, between 700 and 1 300 m. Since 1963, the upper slope species have made regular northward range extensions off of south Portugal to north-western Ireland (about 55 degrees 30' N), more and less rapidly, about 30 years for Cyttopsis roseus and only 6 years for Sphoeroides pachygaster. The continental shelf species, observed from 1969 but mostly from 1981, have a northward range to south-eastern Ireland (about 52 degrees N), but 65.2 % of them have been caught off the south of...

Meiofauna sampling in the proximity of Syd-Hällsö Island (Strömstad, Sweden) revealed a new species of Kinorhyncha from the Skagerrak. The species, Setaphyes elenae sp. nov., is distinguished from its congeners by the arrangement of the middorsal cuticular specializations (it has shortened, distally rounded middorsal processes on segments 1 and 9 and middorsal elevations throughout segments 2–8), as well as by the presence of paired laterodorsal setae on segments 3, 5, 7 and 9 and ventromedial setae on segments 3, 5 and 7 in both males and females. The finding of a new species from the northeastern Atlantic Ocean, provides new valuable information for the recently established genus in the Allomalorhagida.

The European Union requested the H2020 HERA project which aims at setting priorities in research on environment, climate and health, to identify relevant research needs regarding Covid-19. The emergence and spread of SARS-CoV-2 appears to be related to urbanization, habitat destruction, live animal trade, intensive livestock farming and global travel. The contribution of climate and air pollution requires additional studies. Importantly, the severity of COVID-19 depends on the interactions between the viral infection, ageing and chronic diseases such as metabolic, respiratory and cardiovascular diseases and...

Exopolysaccharides produced by marine bacteria and their applications as glycosaminoglycan-like molecules
Provedor de dados: 5
Autores: Delbarre-ladrat, Christine; Sinquin, Corinne; Lebellenger, Lou; Zykwinska, Agata; Colliec-jouault, Sylvia.
Although polysaccharides are ubiquitous and the most abundant renewable bio-components, their studies, covered by the glycochemistry and glycobiology fields, remain a challenge due to their high molecular diversity and complexity. Polysaccharides are industrially used in food products; human therapeutics fall into a more recent research field and pharmaceutical industry is looking for more and more molecules with enhanced activities. Glycosaminoglycans (GAGs) found in animal tissues play a critical role in cellular physiological and pathological processes as they bind many cellular components. Therefore, they present a great potential for the design and preparation of therapeutic drugs. On the other hand, microorganisms producing exopolysaccharides (EPS)...

Autores: De Casamajor, Marie-noelle; Lalanne, Yann.
During recent decades, works on rocky shore biodiversity have been multiplied in the southern part of the Bay of Biscay and more precisely on intertidal and subtidal area were communities present a great interest. Necessity of conservation of coastal habitats and their communities and a growing pressure on coastal environments explain awareness of services provided by these ecosystems. Those communities are very sensitive to water quality change. Moreover, since the beginning of the XXI century various European directives require a good ecological status of coastal waters and conservation of their communities : Water Framework Directive (WFD), Marine Strategy Framework Directive (MSFD) and conservation of habitats with Directive Habitat Fauna and Flora...

Can fish morphology determine its diet?
Provedor de dados: 5
Autores: Chambord, Sophie; Villanueva, Ching-maria; Ernande, Bruno; Lefebvre, Sébastien.
Biodiversity is a concept that covers a lot of issues that can elucidate diversity-related functional roles to understand ecological ecosystem functioning. Biodiversity can shape ecosystem structure and functioning especially if we focus on predator-prey interactions. Moreover, the mechanisms governing prey-predator relationships will shape the emergent food web structure just as individuals’ characteristics determine the emergent demographic structure of a population. We determined the trophic ecology of fish species in the eastern English Channel by combining gut-content and geomorphometric analyses. We inferred the mechanisms of resource utilisation by Atlantic seabass and plaice by coupling measured geomorphometric determinants of prey-predator...

Knowledge for Society. How to limit impacts on marine biodiversity ?
Provedor de dados: 5
Autores: Goulletquer, Philippe.
At the present time, it has been determined that the average fish consumption per inhabitant should double by the year 2030, as it did between 1973 and 2003. Hence, what should we do to better preserve (if not increase) fish stocks that are constantly decreasing? How should aquaculture be considered? Can it meet this growing demand, and if so, what will be its environmental impact? How could developing countries ask aquaculture companies to take care of the extra costs linked to a sustainable aquaculture production?

Atlas of modern dinoflagellate cyst distributions in the Black Sea Corridor: From Aegean to Aral Seas, including Marmara, Black, Azov and Caspian Seas
Provedor de dados: 5
Autores: Mudie, Peta J.; Marret, Fabienne; Mertens, Kenneth; Shumilovskikh, Lyudmila; Leroy, Suzanne A. G.
We present the first comprehensive taxonomic and environmental study of dinoflagellate cysts in 185 surface sediment samples from the Black Sea Corridor (BSC) which is a series of marine basins extending from the Aegean to the Aral Seas (including Marmara, Black, Azov and Caspian Seas). For decades, these low-salinity, semi-enclosed or endorheic basins have experienced large-scale changes because of intensive agriculture and industrialisation, with consequent eutrophication and increased algal blooms. The BSC atlas data provide a baseline for improved understanding of linkages between surface water conditions and dinoflagellate cyst (dinocyst) distribution, diversity and morphological variations. By cross-reference to dinocyst occurrences in sediment cores...

Autores: Cepeda, Diego; Pardos, Fernando; Sánchez, Nuria.
Two new kinorhynch species from Puerto Rico (Greater Antilles) and Barbados (Lesser Antilles) are described herein from Dr R. P. Higgins unexamined Caribbean meiofaunal samples, which have been stored in the Smithsonian Institution collections. The species from Puerto Rico, Cristaphyes cornifrons sp. nov., belongs to the class Allomalorhagida, whereas the species from Barbados, Echinoderes barbadensis sp. nov., belongs to the class Cyclorhagida. Cristaphyes cornifrons sp. nov. is easily distinguished from most of its congeners by the presence of lateral terminal spines and the absence of male, sexually dimorphic, ventromedial tubes on segment 2, as only other two species of the genus lack these features. Of these, C. cornifrons sp. nov. may be easily...

Circulation patterns in the North Atlantic Ocean have changed and re-organized multiple times over millions of years, influencing the biodiversity, distribution, and connectivity patterns of deep-sea species and ecosystems. In this study, we review the effects of the water mass properties (temperature, salinity, food supply, carbonate chemistry, and oxygen) on deep-sea benthic megafauna (from species to community level) and discussed in future scenarios of climate change. We focus on the key oceanic controls on deep-sea megafauna biodiversity and biogeography patterns. We place particular attention on cold-water corals and sponges, as these are ecosystem-engineering organisms that constitute vulnerable marine ecosystems (VME) with high associated...

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...

Trajectoires d’évolution des communautés phytoplanctoniques au cours du processus de restauration écologique des milieux lagunaires méditerranéens
Provedor de dados: 5
Autores: Leruste, Amandine.
Located at the interface between marine and continental systems, coastal lagoons are among the most diverse and productive ecosystems. These semi-enclosed ecosystems are very vulnerable to nutrient enrichment. In the Languedoc-Roussillon region, anthropogenic pressures have profoundly damaged the coastal lagoons, especially those belonging to the Palavasian complex close to Montpellier. The latter lagoons have been affected by high nutrient loadings from the sewage treatment plant of the Montpellier agglomeration. This resulted in a trophic gradient among the eight lagoons in the complex, from mesotrophy to hypertrophy, with altered primary producer communities by favoring the predominance of the phytoplankton compartment.The phytoplankton responds very...

A co-modelling process of social and natural dynamics on the isle of Ouessant: Sheep, turf and bikes
Provedor de dados: 5
Autores: Rouan, Mathias; Kerbiriou, Christian; Levrel, Harold; Etienne, M.
An interdisciplinary team has applied the multi-agent system formalism to study shrub encroachment in the Biosphere Reserve on the isle of Ouessant. The main goals were (1) to understand vegetation dynamics, and (2) to represent how main agents, or actors view the dynamics of natural resources in relation to their own living practices. The management strategies established for each type of stakeholders were formalised and the impact of these strategies on biodiversity was analyzed at various temporal and spatial scales. Following a short description of the model, three aspects of the modelling process are discussed in more detail: the use of the chough (Pyrrhocorax pyrrhocorax) population as a representative variable for the interactions between...

At present there is no consistent approach for the definition of Good Environmental Status (GES) and targets in the Mediterranean Sea, especially for Biodiversity Descriptors, according to the Article 12 of the Marine Strategy Framework Directive (MSFD). The use of plankton indicators in the Mediterranean Sea refers mostly to pelagic habitats in coastal waters and to case studies connected with environmental pressures, e.g. in the Adriatic, Aegean etc. The aim of this review is to study the existing biodiversity indicators for different plankton groups in order to compare GES definitions for the Biodiversity Descriptor and identify the relevant gaps and priority needs to improve coherence for the MSFD implementation across the Mediterranean.

The Gulf of California (GC) is a semi-closed sea in the Tropical Eastern Pacific and is recognised as a highly diverse marine ecosystem. Despite this status, this region is still poorly studied in comparison to other marine hotspots. To start filling this gap, we attempt to provide a global overview of reef-fish diversity around the numerous islands of the region. We evaluated species richness, the abundance and biomass, and the functional diversity of the fish assemblages for the major islands of the GC. We first highlight that the southwestern part of the central GC is the hotspot of reef-fishes diversity within the GC, in terms of species richness, functional diversity, and fish abundance. We then found out an important functional divergence between...

IndiSeas (“Indicators for the Seas”) is a collaborative international working group that was established in 2005 to evaluate the status of exploited marine ecosystems using a suite of indicators in a comparative framework. An initial shortlist of seven ecological indicators was selected to quantify the effects of fishing on the broader ecosystem using several criteria (i.e., ecological meaning, sensitivity to fishing, data availability, management objectives and public awareness). The suite comprised: (i) the inverse coefficient of variation of total biomass of surveyed species, (ii) mean fish length in the surveyed community, (iii) mean maximum life span of surveyed fish species, (iv) proportion of predatory fish in the surveyed community, (v) proportion...

Quand les politiques environnementales attisent les tensions interculturelles en Guyane française
Provedor de dados: 5

This paper shows, from three perspectives, how the environmental policies in French Guiana, trying to deal with the local cultural diversity, tend to ethnicize social relations. The Guiana Amazonian Park, which seems to be a reaffirmation of the state’s presence in the southern French Guiana, experiments modes of governance which increase interethnic competition. The implementation of the Nagoya Protocol on Access to Genetic Resources and the Fair and Equitable Sharing of Benefits Arising from their Utilization has introduced a difference between different categories of the population : some of them must be consulted whereas the others mustn’t. Finally, people from immigration are a blind-spot of these policies. Migrants do not have any facility to access...

Xenophyophores, giant, fragile, agglutinated foraminifera (protists), are major constituents of the abyssal megafauna in the equatorial Pacific Clarion-Clipperton Zone (Ca), a region where seabed mining of polymetallic nodules may occur in the future. As part of a baseline study of benthic communities We made extensive collections of xenophyophores in two areas (UK-1 and OMS) licensed for exploration by the International Seabed Authority. Based on test morphology, we distinguished 36 morphospecies (34 new to science) among 130 specimens. Twenty of these morphospecies yielded 184 DNA sequences, a 14-fold increase in genetic data for xenophyophores that confirms their high diversity in the eastern Ca. A further 15 morphospecies (8 new to science) were...

Integration of shellfish farming activies in three French coastal environments : Mont Saint-Michel Bay, Gulf of Morbihan, and Marennes-Oleron Bay
Provedor de dados: 5
Autores: Mazurie, Joseph; Le Mao, Patrick; Camus, Patrick; Bacher, Cedric; Goulletquer, Philippe.
Integration of shellfish farming along the French shoreline (around 5500 km) has been progressive, as marine bivalve culture is a traditional activity in our country. The history of mussel culture relates that the "bouchot" technique (intertidal culture on wooden poles, producing annually around 60,000 tons) was developed as early as the XIIIth century, by a refugee attempting to capture birds by sticking branches of brushwood along the shore. The European flat oyster, Ostrea edulis, already appreciated at the Roman period, was first cultivated in France after Victor Coste introduced the technique of spat collection at the end of the XIXth century. The Pacific cupped oyster, genus Crassostrea, now the most-cultivated in France (around 120,000 tons marketed...

On March 11th, 2011 the Mw 9.0 2011 Tohoku-Oki earthquake resulted in a tsunami which caused major devastation in coastal areas. Along the Japanese NE coast, tsunami waves reached maximum run-ups of 40 m, and travelled kilometers inland. Whereas devastation was clearly visible on land, underwater impact is much more difficult to assess. Here, we report unexpected results obtained during a research cruise targeting the seafloor off Shimokita (NE Japan), shortly (five months) after the disaster. The geography of the studied area is characterized by smooth coastline and a gradually descending shelf slope. Although high-energy tsunami waves caused major sediment reworking in shallow-water environments, investigated shelf ecosystems were characterized by...

Habitat dynamics interacting with species dispersal abilities could generate gradients in species diversity and prevalence of species traits when the latter are associated with species dispersal potential. Using a process‐based model of diversification constrained by a dispersal parameter, we simulated the interplay between reef habitat dynamics during the past 140 million years and dispersal, shaping lineage diversification history and assemblage composition globally. The emerging patterns from the simulations were compared to current prevalence of species traits related to dispersal for 6315 tropical reef fish species. We found a significant spatial congruence between the prevalence of simulated low dispersal values and areas with a large proportion of...

Determining whether many functionally complementary species or only a subset of key species are necessary to maintain ecosystem functioning and services is a critical question in community ecology and biodiversity conservation. Identifying such key species remains challenging, especially in the tropics where many species co-occur and can potentially support the same or different processes. Here, we developed a new community-wide scan CWS) approach, analogous to the genome-wide scan, to identify fish species that significantly contribute, beyond the socio-environmental and species richness effects, to the biomass and coral cover on Indo-Pacific reefs. We found that only a limited set of species (51 out of approx. 400, = approx. 13%), belonging to various...

Autores: Ginigini, Joape; Lecellier, Gael J.; Nicolas, Mael; Nour, Mohammed; Hnawia, Edouard; Lebouvier, Nicolas; Herbette, Gaetan; Lockhart, Peter; Raharivelomanana, Phila.
Background: Different parts of the tree Calophyllum inophyllum L. (nuts, leaves, roots, bark, fruits, nut oil and resin) are used as traditional medicines and cosmetics in most of the Pacific Islands. The oil efficiency as a natural cure and in traditional cosmetics has been largely described throughout the South Pacific, which led us to investigate C. inophyllum's chemical and genetic diversity. A correlative study of the nut resin and leaf DNA from three distinct archipelagos in the South Pacific was carried out in order to identify diversity patterns in C. inophyllum across the South Pacific. Methods: Calophyllum inophyllum plants were sampled from French Polynesia, New Caledonia and Fiji. We extracted tamanu oil (nut oil) resin for chemo-diversity...

The Gulf of Maine biogeographical information system project: developing a spatial data management framework in support of OBIS
Provedor de dados: 5
Autores: Tsontos, Vm; Kiefer, Da.
Central to the development of an inventory of marine life and improved conceptual understanding of the mechanisms that dynamically shape species distribution patterns is the implementation of strategies aimed at enhancing assimilation and access to existing biogeographical information. Using the Internet as a medium, the Gulf of Maine Biogeographic Information System (GMBIS) project provides a framework and a set of reusable tools for the integration, visualization, analysis and dissemination of diverse types of biogeographical and oceanographic information. End-to-end viability of this approach is demonstrated in the context of a series of scientific storylines and a pilot application for the Gulf of Maine (GoM), a well-studied ecosystem that has been...

Marine fauna of hard substrata of the Cleaver bank and Dogger bank
Provedor de dados: 16
Autores: Schrieken, N.; Gittenberger, A.; Coolen, J.W.P.; Lengkeek, W.
As most of the sea bottom in the Dutch part of the North Sea consists of sand, marine fauna that live in association with hard substrates are rarely monitored. We report here on the results of a species inventory in June 2011 done by scuba-diving while focusing on a wreck on the Dogger Bank and on rocky bottoms on the Cleaver Bank. This resulted in various new records of species for the Dutch part of the North Sea. This result appeared for a large part linked to the added value of monitoring with scuba-divers. It is therefore concluded that scuba-divers should be used in addition to the more traditional  monitoring methods in which dredges and grabs are used, if one aims at getting an accurate view of the biodiversity present in marine regions like the...

A Miocene perspective on the evolution of the Amazonian biota
Provedor de dados: 16
Autores: Wesselingh, F.P.; Salo, J.A.
Between c. 23 and 8 Ma, western Amazonia was occupied by the vast Pebas long-lived lake/wetland system. The Pebas system had a variety of influences over the evolution of Miocene and modern Amazonian biota; it formed a barrier for the exchange of terrestrial biota, a pathway for the transition of marine biota into freshwater Amazonian environments, and formed the stage of remarkable radiations of endemic molluscs and ostracods. The lithological variation of the Pebas Formation has furthermore enhanced edaphic heterogeneity in western Amazonia, sustaining present-day high terrestrial diversity in the region.

The number of described species on the planet is about 1.9 million, with ca. 17,000 new species described annually, mostly from the tropics. However, taxonomy is usually described as a science in crisis, lacking manpower and funding, a politically acknowledged problem known as the Taxonomic Impediment. Using data from the Fauna Europaea database and the Zoological Record, we show that contrary to general belief, developed and heavily-studied parts of the world are important reservoirs of unknown species. In Europe, new species of multicellular terrestrial and freshwater animals are being discovered and named at an unprecedented rate: since the 1950s, more than 770 new species are on average described each year from Europe, which add to the 125,000...

New Scleractinian corals (Cnidaria: Anthozoa) from Sabah, North Borneo. Description of one new genus and eight new species, with notes on their taxonomy and ecology
Provedor de dados: 16
Autores: Ditlev, H.
Eight new species and one new genus of Scleractinian corals from Darvel Bay, North-western Borneo are described and illustrated. Enigmopora darveliensis, Acropora ridzwani, Lithophyllon ranjiti, Pectinia crassa, Mycedium spina, Plerogyra multilobata, Plerogyra diabolotus, and Plerogyra cauliformis. The evolutionary and distributional significance of the species is discussed. Borneo’s unique equatorial location and stable geological history are held responsible for its high diversity of corals with a number of unique species. The morphology of Enigmopora darveliensis is discussed and compared to other supposedly primitive extant corals. The endemic status of most of the Plerogyra species, with their unusually large polyps, is due to their narrow ecological...

A re-appraisal of Harknessia (Diaporthales), and the introduction of Harknessiaceae fam. nov.
Provedor de dados: 16
Autores: Crous, P.W.; Summerell, B.A.; Shivas, R.G.; Carnegie, A.J.; Groenewald, J.Z.
Harknessiaceae is introduced as a new family in the ascomycete order Diaporthales to accommodate species of Harknessia with their Wuestneia-like teleomorphs. The family is distinguished by having pycnidial conidiomata with brown, furfuraceous margins, brown conidia with hyaline, tube-like basal appendages, longitudinal striations, and rhexolytic secession. Six species occurring on Eucalyptus are newly introduced, namely H. australiensis, H. ellipsoidea, H. pseudohawaiiensis, and H. ravenstreetina from Australia, H. kleinzeeina from South Africa, and H. viterboensis from Italy. Epitypes are designated for H. spermatoidea and H. weresubiae, both also occurring on Eucalyptus. Members of Harknessia are commonly associated with leaf spots, but also occur as...

Community ecology of tropical forest snails: 30 years after Solem
Provedor de dados: 16
Autores: Schilthuizen, M.
Since Solem’s provocative claim in the early 1980s that land snails in tropical forests are neither abundant nor diverse, at least 30 quantitative-ecological papers on tropical land snail communities have appeared. Jointly, these papers have shown that site diversity is, in fact, high in tropical forests; often more than 100 species have been recorded per site, which is somewhat more than normally found at sites in higher latitudes. At the same time, however, point diversities (which usually range between 10 and 30 species per quadrat) appear to be no different from the ones recorded for temperate localities, which suggests that the number of ways in which syntopic resource space can be subdivided among different land snail species has an upper limit that...

Mucormycosis usually presents as a progressive infection with significant angio-invasion. Mucormycosis due to Mucor irregularis (formerly Rhizomucor variabilis var. variabilis), however, is exceptional in causing chronic cutaneous infection in immunocompetent humans, ultimately leading to severe morbidity if left untreated. More than 90 % of the cases known to date were reported from Asia, mainly from China. The nearest neighbour of M. irregularis is the saprobic species M. hiemalis. The aim of this study was to evaluate the taxonomic position, epidemiology, and intra- and inter-species diversity of M. irregularis based on 21 strains (clinical n = 17) by multilocus analysis using ITS, LSU, RPB1 and RPB2 genes, compared to results of cluster analysis with...

Biodiversity on the marginal coral reefs of South Africa: What does the future hold?
Provedor de dados: 16
Autores: Schleyer, M.H.; Celliers, L.
Southern African coral communities form a continuum from the more typical, accretive reefs in the tropics of Mozambique to the marginal, southernmost African distribution of this fauna in KwaZulu- Natal. While the latter are limited in size, they are gaining increasing attention as they provide a model for the study of many of the stresses to which these valuable systems are globally being subjected. Soft coral cover, comprising relatively few species, exceeds that of scleractinians over much of the southern reefs, and the coral communities attain a high biodiversity at this latitude on the East African coast. A long-term monitoring programme has revealed small yet significant changes in community structure on the reefs in recent years, concurrent with...

How many hydrozoan species are there?
Provedor de dados: 16
Autores: Schuchert, P.
A list of all living hydrozoan species was compiled and analysed. The number of supposedly valid species was found to be around 3200. Considerable uncertainties exist due to the possibly high number of invalid nominal species. The total number of existing hydrozoan species cannot be estimated because the accumulation curve for new species shows no sign of convergence. Only in the Thecata, Narcomedusae and Trachymedusae is an estimate of the maximal number feasible. However, application of new methods, notably a molecular systematic approach, could drastically alter these predictions.

Novel fungi from an ancient niche: cercosporoid and related sexual morphs on ferns
Provedor de dados: 16
Autores: Guatimosim, E.; Schwartsburd, P.B.; Barreto, R.W.; Crous, P.W.
The fern flora of the world (Pteridophyta) has direct evolutionary links with the earliest vascular plants that appeared in the late Devonian. Knowing the mycobiota associated to this group of plants is critical for a full understanding of the Fungi. Nevertheless, perhaps because of the minor economic significance of ferns, this niche remains relatively neglected by mycologists. Cercosporoid fungi represent a large assemblage of fungi belonging to the Mycosphaerellaceae and Teratosphaeriaceae (Ascomycota) having cercospora-like asexual morphs. They are well-known pathogens of many important crops, occurring on a wide host range. Here, the results of a taxonomic study of cercosporoid fungi collected on ferns in Brazil are presented. Specimens were obtained...

Species from Entoloma subg. Entoloma are commonly recorded from both the Northern and Southern Hemispheres and, according to literature, most of them have at least Nearctic-Palearctic distributions. However, these records are based on morphological analysis, and studies relating morphology, molecular data and geographical distribution have not been reported. In this study, we used phylogenetic species recognition criteria through gene genealogical concordance (based on nuclear ITS, LSU, rpb2 and mitochondrial SSU) to answer specific questions considering species limits in Entoloma subg.

Species of Leucadendron, Leucospermum and Protea (Proteaceae) are in high demand for the international floriculture market due to their brightly coloured and textured flowers or bracts. Fungal pathogens, however, create a serious problem in cultivating flawless blooms. The aim of the present study was to characterise several of these pathogens using morphology, culture characteristics, and DNA sequence data of the rRNA-ITS and LSU genes. In some cases additional genes such as TEF 1-α and CHS were also sequenced. Based on the results of this study, several novel species and genera are described. Brunneosphaerella leaf blight is shown to be caused by three species, namely B. jonkershoekensis on Protea repens, B. nitidae sp. nov. on Protea nitida and B....

The order Mucorales comprises predominantly fast-growing saprotrophic fungi, some of which are used for the fermentation of foodstuffs but it also includes species known to cause infections in patients with severe immune or metabolic impairments. To inventory biodiversity in Mucorales ITS barcodes of 668 strains in 203 taxa were generated covering more than two thirds of the recognised species. Using the ITS sequences, Molecular Operational Taxonomic Units were defined by a similarity threshold of 99 %. An LSU sequence was generated for each unit as well. Analysis of the LSU sequences revealed that conventional phenotypic classifications of the Mucoraceae are highly artificial. The LSU- and ITS-based trees suggest that characters, such as rhizoids and...

Autores: Silva, M.; Barreto, R.W.; Pereira, O.L.; Freitas, N.M.; Groenewald, J.Z.; Crous, P.W.
Although the genus Pseudocercospora has a worldwide distribution, it is especially diverse in tropical and subtropical countries. Species of this genus are associated with a wide range of plant species, including several economically relevant hosts. Preliminary studies of cercosporoid fungi from Brazil allocated most taxa to Cercospora, but with the progressive refinement of the taxonomy of cercosporoid fungi, many species were relocated to or described in Pseudocercospora. Initially, species identification relied mostly on morphological features, and thus no cultures were preserved for later phylogenetic comparisons. In this study, a total of 27 Pseudocercospora spp. were collected, cultured, and subjected to a multigene analysis. Four genomic regions...

Autores: Bakhshi, M.; Arzanlou, M.; Babai-ahari, A.; Groenewald, J.Z.; Braun, U.; Crous, P.W.
The genus Cercospora includes many important plant pathogenic fungi associated with leaf spot diseases on a wide range of hosts. The mainland of Iran covers various climatic regions with a great biodiversity of vascular plants, and a correspondingly high diversity of cercosporoid fungi. However, most of the cercosporoid species found to date have been identified on the basis of morphological characteristics and there are no cultures that support these identifications. In this study the Consolidated Species Concept was applied to differentiate Cercospora species collected from Iran. A total of 161 Cercospora isolates recovered from 74 host species in northern Iran were studied by molecular phylogenetic analysis. Our results revealed a rich diversity of...

Ecological relevance of shipwrecks in the North Sea
Provedor de dados: 16
Autores: Lengkeek, W.; Coolen, J.W.P.; Gittenberger, A.; Schrieken, N.
This paper reports on observations made during wreck dive expeditions in 2010-2012, in order to investigate the ecological relevance of shipwrecks on the Dutch Continental Shelf (dcs). Shipwrecks are biodiversity hotspots. The number of species recorded on shipwrecks is similar to the number of species found in soft bottoms of the entire dcs. The soft substrates, however, represent a vastly larger habitat on the dcs than the shipwrecks. Amongst many other taxa, juvenile and large Atlantic cod, linear skeleton shrimp, goldsinny wrasses and leopard spotted gobies were found in the shipwreck habitats. The presence of these important species and their absence from many other habitats, illustrate that shipwrecks function as key habitats, nurseries, and refugia...

Notes on the genus Mama Belokobylskij (Hymenoptera: Braconidae: Euphorinae), and on the use of monotype taxa
Provedor de dados: 16
Autores: Simbolotti, G.; Villemant, C.; Achterberg, C. van.
The genus Mama Belokobylskij, 2000 (Braconidae; Euphorinae) is re-assessed and the type species is compared with three similar species: Microctonus cephalicus Provancher, 1886, Microctonus reclinator Ruthe, 1856, and Euphorus spiniscapus Muesebeck, 1936. The results are discussed in relation to the use of taxa based on one specimen (“monotype taxa”). Problems concerning our knowledge of important groups of Euphorinae are outlined. The context of the peculiarly tangled taxonomical situation, which this paper deals with, is considered to be widespread in parasitoid taxonomy, and should be borne in mind in current studies of parasitoid biodiversity assessment.

The phylogenetic position of the solitary zoanthid genus Sphenopus (Cnidaria: Hexacorallia)
Provedor de dados: 16
Autores: Reimer, J.D.; Lin, M.; Fujii, T.
The zoanthid genus Sphenopus (Cnidaria: Anthozoa: Zoantharia), like many other brachycnemic zoanthids, is found in shallow subtropical and tropical waters, but is uniquely unitary (solitary, monostomatous), azooxanthellate, and free-living. With sparse knowledge of its phylogenetic position, this study examines the phylogenetic position of Sphenopus within the family Sphenopidae utilizing specimens from southern Taiwan and Brunei collected in 1999-2011, and furthermore analyzes the evolution of its unique character set via ancestral state reconstruction analyses. Phylogenetic analyses surprisingly show Sphenopus to be phylogenetically positioned within the genus Palythoa, which is colonial (polystomatous), zooxanthellate, and attached to solid substrate....

Autores: Voogd, N.J. de; Cleary, D.F.R.; Hoeksema, B.W.; Noor, A.; Soest, R.W.M. van.
Sponge assemblages were investigated in the Spermonde Archipelago, southwestern Sulawesi, Indonesia. In this study spatial patterns of sponge similarity among sites were significantly related to remotely sensed environmental variables, the degree of human settlement and depth, but not to the distance between sites. Both oviparous and viviparous species groups responded to similar environmental constraints, and differences in similarity were unrelated to the distance between sites. The degree of human settlement, however, was significantly related to variation in the composition of viviparous, but not oviparous species. Our results demonstrate, most importantly, the utility of remotely sensed data in predicting the spatial turnover of diverse species...

Autores: Fox, R.; Warren, M.; Harding, P.; Asher, J.; Jeffcoate, G.; Jeffcoate, S.
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...

The Parotoplana jondelii species-group (Platyhelminthes: Proseriata): a microturbellarian radiation in the Mediterranean
Provedor de dados: 16
Autores: Delogu, V.; Curini-Galletti, M.
Seven new Parotoplana species (Proseriata: Otoplanidae) from the Mediterranean, belonging to the P. jondelii complex, are described. They are characterized by the presence of numerous (14-22) copulatory spines. These are characteristically broad, and arranged in a girdle around the distal portion of the ejaculatory duct. In most species, dorsal and ventral spines are distinctly different from the rest of the spines of the girdle. This morphology of the copulatory spines is apomorphic for the genus Parotoplana, and supports a close relationship among these species. The new species (P. axi sp. n., P. crassispina sp. n., P. carthagoensis sp. n., P. gracilispina sp. n., P. ichnusae sp. n., P. obtusispina sp. n., P. pulchrispina sp. n.) are distinguished by...

Zoantharia (Cnidaria: Anthozoa: Hexacorallia) of the South China Sea and Gulf of Thailand: a species list based on past reports and new photographic records
Provedor de dados: 16
Autores: Reimer, J.D.; Wee, H.B.; Put, A.; Hoeksema, B.W.
This study is the first review of Zoantharia species in the South China Sea and Gulf of Thailand. In addition to past literature records, new field observations are added from previously unexamined countries and regions. In total 16 species are listed, 15 of which belong to suborder Brachycnemina, and only one to suborder Macrocnemina. Two species are undescribed. The lack of Macrocnemina species is not likely indicative of a low diversity of this suborder in the South China Sea and Gulf of Thailand, but instead of an absence of research below shallow subtidal depths. As the majority of the new records from this study were randomly compiled by researchers who are not experts of Zoantharia, specific surveys by experts are needed in these two marine regions....

The Amazonian rainforest is arguably the most species-rich terrestrial ecosystem in the world, yet the timing of the origin and  volutionary causes of this diversity are a matter of debate. We review the geologic and phylogenetic evidence from Amazonia and compare it with uplift records from the Andes. This uplift and its effect on regional climate fundamentally changed the Amazonian landscape by reconfiguring drainage patterns and creating a vast influx of sediments into the basin. On this “Andean” substrate, a region-wide edaphic mosaic developed that became extremely rich in species, particularly in Western Amazonia. We show that Andean uplift was crucial for the evolution of Amazonian landscapes and ecosystems, and that current biodiversity patterns...

A biosystematic basis for pelagic biodiversity
Provedor de dados: 16
Autores: Spoel, S. van der.
Biodiversity can be considered to be a human appreciation of the biological entity diversity. Diversity can be expressed numerically on the basis of taxa found, but it can also be expressed as the contribution of a specimen to the diversity, for which a formula is proposed. Diversity is the sum of the taxonomic or numerical diversity, and the ecological, genetical, historical, and phylogenetic diversity. Moreover, each group, or larger taxon, has its own characteristic diversity. These types of diversity are considered separately. One formula is tentatively proposed to calculate the overall diversity. Diversity in nature is variable, which is demonstrated in a diagram for comparison with societyinduced diversity changes. Diversity in the pelagic fluctuates...

Unforeseen importance of historical collections as baselines to determine biotic change of coral reefs: the Saba Bank case

Botanical and zoological collections may serve as archives for historical ecological research on the effects of global change and human impact on coral reef biota. Museum collections may harbour old specimens of reef-dwelling species that have become locally extinct. Such collections also help to determine whether early records of invasive species can be obtained from times when they were not yet recognized as such. A case study (2006) involving Saba Bank, Caribbean Netherlands (former Netherlands Antilles), suggests that the coral reef fauna here may have become impoverished when compared with data obtained during an earlier expedition in 1972. However, the 1972 sampling may have been incomplete, as it was performed by professional divers who were not...

High diversity and morphological convergence among melanised fungi from rock formations in the Central Mountain System of Spain
Provedor de dados: 16
Autores: Ruibal, C.; Platas, G.; Bills, G.F.
Melanised fungi were isolated from rock surfaces in the Central Mountain System of Spain. Two hundred sixty six isolates were recovered from four geologically and topographically distinct sites. Microsatellite-primed PCR techniques were used to group isolates into genotypes assumed to represent species. One hundred and sixty three genotypes were characterised from the four sites. Only five genotypes were common to two or more sites. Morphological and molecular data were used to characterise and identify representative strains, but morphology rarely provided a definitive identification due to the scarce differentiation of the fungal structures or the apparent novelty of the isolates. Vegetative states of fungi prevailed in culture and in many cases could...

A survey of the endophagous insects fauna associated to Asteraceae capitula was carried out from 2000 to 2002 in eight cerrado sensu stricto sites located in the Brazilian state of São Paulo. Sixty-four endophagous species of Diptera and Lepidoptera were recorded from 49 asteracean host plants. Approximately half of the species were obtained from a single locality, with a large proportion emerging from a single sample (unicates). Thirty percent of the species were singletons (i.e. only one individual was recorded). The large proportion of rare species suggests a high species turnover among localities. Lepidopteran species were recorded on more host species than dipterans, confirming their more polyphagous food habit, also observed in other Brazilian biomes...

Barcoding lepidoptera: current situation and perspectives on the usefulness of a contentious technique
Provedor de dados: 82
Autores: Silva-Brandão,Karina L; Lyra,Mariana L; Freitas,André V L.
Faced by a growing need of identification and delimitation of new and established cryptic species that are being lost at an increasing rate, taxonomists can now more than ever take advantage of an enormous variety of new molecular and computational tools. At this moment they should be open to all new available technologies in the so called "technology-driven revolution" in systematics. The use of the "DNA barcode" has been discussed by those applying successfully this approach to identify and diagnose species and by those who believe that the flaws in the use of this molecular marker are as many as to negate the worth of its employment. For insects of the order Lepidoptera neither side seems totally correct orwrong, and although many groups of...

Autores: Toni,Daniela C. de; Gottschalk,Marco S.; Cordeiro,Juliana; Hofmann,Paulo P.R.; Valente,Vera L.S.
A study of the community dynamics of Drosophilidae was carried out in six insular communities and two others on the mainland. Seasonal collections were carried out throughout two years in Santa Catarina State, southern of Brazil. The diversity index calculations show high values when compared with temperate climate communities. The sites on the mainland (Serra do Tabuleiro) presented the highest diversity, which was measured by the Diversity Index (H'). These sites are covered by primary Atlantic Forest and theoretically should have a higher variation of ecological niches. A dendogram showing the similarity between the communities, calculated by Morisita Index, points to a level of similarity equal to 60% for all communities. In this diagram, we can see...

Distribution and Habitat in Mexico of Dactylopius Costa (Hemiptera: Dactylopiidae) and their Cacti Hosts (Cactaceae: Opuntioideae)
Provedor de dados: 82
Autores: Chávez-Moreno,CK; Tecante,A; Casas,A; Claps,LE.
The distribution pattern of species of the genus Dactylopius Costa in Mexico was analyzed in relation to the distribution of their host plants (subfamily Opuntioideae) to evaluate the specificity of the insect-host association. The distribution of Dactylopius currently recognized is narrower than that of its hosts and probably is not representative. Therefore, a broader distribution of the Dactylopius species in correspondence with those of their hosts was hypothesized. Insects and their hosts were collected and georeferenced in 14 states of Mexico from 2005 to 2007. The distribution areas, maps, and habitat characteristics of Dactylopius, Opuntia sensu stricto, Nopalea and Cylindropuntia were determined on the basis of field collections and examination of...

The aim of this study is to explain the effect of soil use on ant communities. We tested the hypothesis that there was a decrease in ant species richness and a change in the species composition at habitats with more intense soil use. We collected ants using sardine baits, subterranean traps and direct sampling at four habitats with different soil use (secundary forest, Acacia forestry, initial stage of succession and mixed crops). The ant species richness did not decrease with intensity of soil use. In successional habitat the species numbers collected using sardine baits and subterranean traps were...

Autores: Schmitz,Hermes J.; Valente,Vera L.S.; Hofmann,Paulo R.P.
Assemblages of drosophilids have been characterised in several environments of the Brazilian territory, like the Atlantic Rain Forest, urban areas, cerrados, the Amazon Forest, and others. The present survey is the first attempt to characterise the fauna of Drosophilidae in mangrove forests, an environment typical of tropical coasts worldwide. Twenty-eight samples were collected from the three main mangrove forests of Santa Catarina Island, southern Brazil, using banana-baited traps hung in trees. Samples were taken in January (summer), April (autumn), July (winter) and October (spring) between July 2002 and July 2005. In total, 82,942 specimens of drosophilids were caught, belonging to 69 species of six genera - Amiota Loew, Drosophila Fallén, Leucophenga...

Autores: Morais,José W de; Oliveira,Viviane dos S; Dambros,Cristian de S; Tapia-Coral,Sandra C; Acioli,Agno N S.
The mesofauna has an important function in the soil and it is represented mainly by Acari Oribatida and Collembola. We report the first data on the density and diversity of the soil mesofauna in Benjamin Constant, Amazonas State, Brazil. The following systems were evaluated: primary forest, secondary forest, agroforestry system, cultivated areas and pastures. A total of 101 samples were collected 100 m apart from each other and specimens were collected by using Berlese-Tullgren method. The highest density was registered in secondary forest (29,776 specimens.m-2). Acari Oribatida was the dominant group (7.072 specimens.m-2) in the pasture, suggesting that mites show higher capacity of adaptation to disturbed environments and/or due to the presence of...

Autores: Reis,Roberto E.
ABSTRACT A taxonomic revision of Eurycheilichthys is provided, and seven new species are described in addition to the two previously known species in this genus: E. pantherinus from the upper rio Uruguay, and E. limulus from the upper rio Jacuí. The genus is diagnosed based on the uniquely derived presence of seven branched pectoral-fin rays, and on the possession of reduced filamentous gill rakers in the oral surface of the hyobranchial skeleton, and presence of a distinct fleshy flap along the posterodorsal margin of the pectoral-fin spine in adult males. The seven new species are described from tributaries to the rio Taquari basin, itself a tributary to the rio Jacuí in Rio Grande do Sul State, southern Brazil. The new species are diagnosed based on...

A new species of sand-dwelling catfish, with a phylogenetic diagnosis of Pygidianops Myers (Siluriformes: Trichomycteridae: Glanapteryginae)
Provedor de dados: 83
Autores: Pinna,Mário C. C. de; Kirovsky,Alexandre L.
A new species of sand-dwelling catfish genus Pygidianops, P. amphioxus, is described from the Negro and lower Amazon basins. The new species differs from its three congeners in the elongate eel-like body, the short barbels, and the small caudal fin, continuous with the body, among other traits of internal anatomy. The absence of anal fin further distinguishes P. amphioxus from all other Pygidianops species except P. magoi and the presence of eyes from all except P. cuao. The new Pygidianops seems to be the sister species to P. magoi, the two species sharing a unique mesethmoid with a dorsally-bent tip lacking cornua, and a produced articular process in the palatine for the articulation with the neurocranium. Pygidianops amphioxus is a permanent and...

Provedor de dados: 83
Autores: Martins,Fernanda O.; Langeani,Francisco.
ABSTRACT Our analyses showed that the type series of Hisonotus notatus , type species of the genus, is mixed, composed by two different species. Based on that, we redescribe H. notatus with the designation of a lectotype, restricting the species to rio São João drainage and other small coastal drainages running to the Baía de Guanabara and to the Baía de Sepetiba in Rio de Janeiro State. We also describe a new species of Hisonotus from drainages of the rio Paraíba do Sul, Lagoa Feia, rio Macaé, and coastal rivers of Espírito Santo State, from rio Itabapoana to rio Doce basin. These two species are sister-taxa and can be distinguished by the number of plates in the mid-dorsal series.

Miniature catfishes of the genus Gelanoglanis (Siluriformes: Auchenipteridae): monophyly and the description of a new species from the upper rio Tapajós basin, Brazil
Provedor de dados: 83
Autores: Calegari,Bárbara B.; Reis,Roberto E.; Vari,Richard P.
Previously proposed synapomorphies for the genus Gelanoglanis of the catfish family Auchenipteridae are evaluated and four additional features involving the relationship between the mesethmoid and premaxilla, the very fleshy anterior portion of the snout, the lack of ossification of the second through fourth infraorbitals, and the incomplete poring of the lateral line are hypothesized as synapomorphic for the members of the genus. A new species of Gelanoglanis is described based on a series of specimens collected in the rio Teles Pires, a tributary of the rio Tapajós in the southern reaches of the Amazon basin. The new species demonstrates a number of features unusual within Gelanoglanis including a fontanel bordered by the frontals, a particularly...

ABSTRACT The Brazilian North coast is one of the world’s most important shrimp fishery grounds, with a total area of approximately 223,000 km2. However, the available data on the diversity of fish caught by the region’s industrial trawler fleet are limited to the commercially-valuable species. This lacuna in the data on the region’s marine fish fauna is worrying, both for the management of stocks and the conservation of the local biodiversity. The present study was based on a comprehensive inventory of the teleost fishes captured by the industrial outrigger trawling operations off the North coast of Brazil. This inventory recorded 201 species belonging to 64 families and 20 orders, and revealed a unique fauna, characterized by 17 endemic species, and a...

Phylogenetic relationships of the species of Acestridium Haseman, 1911 (Siluriformes: Loricariidae)
Provedor de dados: 83
Autores: Rodriguez,Mónica S.; Delapieve,Maria Laura S.; Reis,Roberto E.
A phylogeny of the species of the loricariid genus Acestridium and relevant outgroups is presented based on a parsimony analysis of 52 unweighted and unordered morphological characters. Acestridium is diagnosed as monophyletic based on the possession of the 17 exclusive synapomorphies. Two primary trees were found, and the strict consensus among those alternative trees resulted in the following relationships: ((A. dichromum + A. triplax)(A. gymnogaster + A. scutatum + (A. discus (A. colombiensis + A. martini)))). Acestridium was found to be sister to Niobichthys with this clade subsequently the sister-group to Oxyropsis + Hypoptopoma.

Autores: Chuctaya,Junior; Bührnheim,Cristina M.; Malabarba,Luiz R.
ABSTRACT Specimens historically identified as Odontostilbe microcephala from the upper rio Paraná and Andean piedmont tributaries of the río Paraguay are reviewed and split in three species. We found that the distribution of O. microcephala is restricted to the Andean slope of the río Paraguay basin. The species is distinguished from congeners with subterminal mouth by the elongate body, usually 10-12 gill rakers on upper branch and smaller horizontal orbital diameter (24.6-32.8 % HL, mean 28.7%). Specimens from upper rio Paraná constitute two new species, diagnosed from other Cheirodontinae by the presence of mesopterygoid teeth, grouped on median portion and forming a continuous row. The new species are distinguished from each other by having...

Provedor de dados: 83
Autores: Carvalho,Tiago P.; Albert,James S.
We redescribe Iracema caiana, a monotypic genus of the gymnotiform electric fish family Rhamphichthyidae. Iracema is known only from the type series (holotype and three paratypes) collected from the rio Jauaperi, affluent to the rio Negro in the Amazon basin, and was never collected again. Previous morphological studies were limited to features of external morphology. To study the osteology of Iracema we examined two specimens of different sizes using high-resolution x-ray computed tomography, a non-invasive and non-destructive technique to visualize internal anatomical structures. We describe and illustrate the osteology of Iracema caiana, and present data on morphometrics and external morphology. Contrary to previous hypotheses we propose that Iracema is...

Autores: Bitencourt,Jamille de Araújo; Affonso,Paulo Roberto Antunes de Mello; Giuliano-Caetano,Lucia; Dias,Ana Lucia.
Few chromosomal reports are available for the endemic fish fauna from coastal basins in northeastern Brazil, and regional biodiversity remains partially or completely unknown. This is particularly true for Loricariidae, the most diverse family of armored catfishes. In the present work, allopatric populations of Hypostomus cf. wuchereri (Siluriformes: Loricariidae) from two basins in Bahia (northeastern Brazil) were cytogenetically analyzed. Both populations shared 2n = 76 chromosomes, a karyotype formula of 10m+18sm+48st/a (FN = 104) and single terminal GC-rich NORs on the second metacentric pair. Nevertheless, microstructural differences were detected by C-banding, fluorochrome staining and chromosomal digestion with restriction enzymes (Alu I, Bam HI,...

ABSTRACT Studies on the diversity, taxonomy, phylogeny, and biogeography of Neotropical Fishes have thrived over the twenty years that have elapsed since the first symposium on their phylogeny and classification in Porto Alegre, Brazil. Here, we review recent advances in the study of Neotropical fishes and assess the known diversity of freshwater species in that region. 6,255 valid freshwater species have been discovered in the Neotropics so far, and we estimate that over 9,000 species will be known when the inventory is complete. We also summarize the events of the second Symposium on Phylogeny and Classification of Neotropical Fishes that took place last year in Londrina, Brazil. Along with invited talks on the biodiversity of all major groups of...

Movements through a fish ladder: temporal patterns and motivations to move upstream
Provedor de dados: 83
Autores: Agostinho,Carlos Sérgio; Pereira,Celiana Ribeiro; Oliveira,Rafael José de; Freitas,Iriene Siqueira; Marques,Elineide Eugênio.
Fish passages are constructed with the aim of reestablishing connectivity between critical habitats, in order to sustain those species that move over a large area during their lives. The upstream movements of most of the known migratory species are made for purposes of reproduction (adults) or dispersal (juveniles). The present study was conducted at the ladder constructed at Lajeado Dam (Luis Eduardo Magalhães Hydroelectric Power), on the Tocantins River. The objective was to assess whether there is a temporal pattern in the abundance of fish below the dam and in the ladder, that correlates with their breeding seasons. Additionally, it was examined whether reproduction is the predominant motivation of the shoals of fish that ascend the ladder. Samples...

A new species of Gymnotus (Gymnotiformes: Gymnotidae) from the Fitzcarrald Arch of southeastern Peru
Provedor de dados: 83
Autores: Maxime,Emmanuel L.; Albert,James S.
Herein Gymnotus chaviro is described from the Alto Yuruá (upper rio Juruá) of southeastern Peru, where it is locally abundant in terra firme streams and floodplain oxbow lakes, and occurs sympatrically and syntopically with the type species of the genus G. carapo. The new species is diagnosed by a unique combination of morphometric, meristic, and osteological traits, and a characteristic color pattern in which the dark band-pairs are unbranched and incompletely separated, and the pale inter-bands rarely reach to the dorsal mid-line on the anterior half of the body, being crescent-shaped in abdominal area. Gymnotus chaviro is a member of the G. carapo species group, with which it shares the presence of two pores in the dorsolateral portion of the...

Historical biogeography of fishes from coastal basins of Maranhão State, northeastern Brazil
Provedor de dados: 83
Autores: Abreu,João Marcelo S.; Craig,Jack M.; Albert,James S.; Piorski,Nivaldo M.
ABSTRACT The Amazonian ichthyofauna is one of the most diverse in the world, yet fishes from the adjacent coastal basins of Maranhão State in Northeastern Brazil remain poorly known. We use phylogeographic, community phylogenetic and phylogenetic beta diversity methods to study the biogeographic history of fishes from the coastal basins of Maranhão State. We report a total of 160 fish species from the basins of the Maranhão region, representing a 93% increase over results of previous studies. All the fish species assemblages from Maranhão are polyphyletic, with only a few putative sister species pairs inhabiting the region. The modern watershed divides among Maranhão basins do not form substantial barriers to dispersal for freshwater fish species, and are...

A new species of Tetragonopterus (Characiformes: Characidae) from Central Amazon lowlands, Brazil
Provedor de dados: 83
Autores: Urbanski,Bruna Q.; Melo,Bruno F.; Silva,Gabriel S. C.; Benine,Ricardo C.
ABSTRACT A new species of Tetragonopterus is described from lowland rivers of Central Amazon. It differs from congeners by having a vertically-oriented patch of dark pigmentation limited to posterior portion of the caudal peduncle and by bearing five thin and sharp teeth on dentary, along with other morphometric and meristic features. We hypothesize that the new taxon belongs to the herein named “Tetragonopterus anostomus clade” that includes T. anostomus, T. denticulatus, T. kuluene, and T. juruena.

Autores: Manzotti,Angelo Rodrigo; Ceneviva-Bastos,Mônica; Teresa,Fabrício Barreto; Casatti,Lilian.
ABSTRACT Habitat homogenization has been a major impact in stream ecosystems, and it is considered one of the main drivers of biotic homogenization as well, leading to the loss of water quality and fish diversity. In this study, we added artificial woody structures and leaf packs in physically impacted streams to test if the additions can improve habitat complexity and change the taxonomic and functional structure of fish communities. The experiment was done in eight streams impacted by siltation, deforestation, and habitat homogeneization, inserted in an agricultural landscape from the Upper Paraná River Basin, and lasted 112 days. The provision of artificial microhabitats increased instream habitat diversity by creating patches of organic matter...

A new genus of Neotropical rheophilic catfishes, with four new species (Teleostei: Siluriformes: Pseudopimelodidae)
Provedor de dados: 83
Autores: Shibatta,Oscar Akio; Vari,Richard P.
ABSTRACT Rhyacoglanis, a new genus of the South American freshwater catfish family Pseudopimelodidae is described from cis-Andean portions of the continent. Rhyacoglanis is distinguished from other genera of the family by three synapomorphies: presence of a light blotch on the cheek; a connection between the middle of the dark caudal-fin stripe and the dark caudal-peduncle pigmentation; and 30-35 total vertebrae. Species of Rhyacoglanis are rheophilic and strongly associated with rapids and other swift-flowing waters. A phylogenetic analysis based on 41 morphological characters yields a hypothesis of monophyly of the Pseudopimelodidae and Rhyacoglanis. Pimelodus pulcher Boulenger, 1887, from the western Amazon basin is designated as type-species of the new...

A history of the biogeography of Amazonian fishes
Provedor de dados: 83
Autores: Dagosta,Fernando C. P.; Pinna,Mário C. C. de.
ABSTRACT The history of knowledge about Amazonian biogeography is as rich as its fish community, and a fascinating theme of study in itself. Several current paradigms and controversies about Amazonian fish biogeography are rooted in principles dating from the second half of the 18th to the first half of the 19th centuries. The present work establishes a relationship between current biogeographical ideas and their old predecessors, on the basis of a chronologically-oriented historical continuity analysis. The advent of evolutionary theory has not contributed significantly to a transformation of the knowledge on the biogeography of Amazonian fishes. On the other hand, the two main schools of biogeographical thought (dispersalist and vicariant) had major...

Autores: Júlio Júnior,Horácio Ferreira; Tós,Claudenice Dei; Agostinho,Ângelo Antonio; Pavanelli,Carla Simone.
Based on long-term studies in the upper rio Paraná basin, in addition to a broad review of literature and other information, we were able to identify 33 species of native fishes in the lower rio Paraná basin that successfully colonized the upper rio Paraná after Itaipu impoundment, that flooded the natural geographic barrier constituted by the Sete Quedas Falls. These species belong to six Orders, encompassing two of Myliobatiformes, six of Characiformes, 17 of Siluriformes, six of Gymnotiformes, one of Perciformes, and one of Pleuronectiformes. Extensive remarks regarding each species, including their influence upon the native assemblage, in addition to comments on other non-indigenous species, are also provided. We conclude that, in spite of its...

Reproduction of two loricariid species in a confined river and implications for environmental impacts of dams
Provedor de dados: 83
Autores: De Fries,Lucas; Rosa,Gilberto da; Silva,José Pezzi da; Vilella,Fábio Silveira; Becker,Fernando Gertum.
ABSTRACT Fish reproduction in floodplain rivers is often linked to flow regime and with the inundation of floodplain habitats. However, in confined rivers, where floodplains are absent, the relation between reproduction and flow can in comparison be expected to be distinct. In this study, we describe the reproductive life-history of Hemiancistrus fuliginosus and Hypostomus isbrueckeri in a confined river and discuss its differences relative to floodplain loricariids and also the implications for effects of dam construction and flow regulation. We found the reproductive peak of both species occurred during lowering waters, just after maximum river flow, in contrast to floodplain species that tend to spawn during rising waters. The studied species presented...

Autores: Agostinho,Carlos Sérgio; Agostinho,Angelo Antônio; Pelicice,Fernando; Almeida,Deusimar Augusto de; Marques,Elineide Eugênio.
Although dozens of fish ladders have been constructed at dams of Brazilian reservoirs, there are few studies evaluating their efficiency as a tool for the conservation of Neotropical ichthyofauna, especially for migratory species. Therefore, the present study evaluated the selectivity of the species that entered and ascended the fish ladder located next to Lajeado Dam (Luis Eduardo Magalhães Hydroelectric Power Plant) on the Tocantins River. Samples were taken monthly from November, 2002 through October, 2003, in the resting pools of the ladder, using cast nets, and in the downstream stretch, using gillnets. The selectivity of the ladder in attracting fish was evaluated by comparing the occurrence, relative abundance, dominance and the congruence of...

Autores: Craig,Jack M.; Carvalho,Tiago P.; Chakrabarty,Prosanta; Derouen,Valerie; Ortega,Hernán; Petry,Paulo; Reis,Roberto E.; Tagliacollo,Victor A.; Albert,James S.
ABSTRACT Here we explore the use of community phylogenetics as a tool to document patterns of biodiversity in the Fitzcarrald region, a remote area in Southwestern Amazonia. For these analyses, we subdivide the region into basin-wide assemblages encompassing the headwaters of four Amazonian tributaries (Urubamba, Yuruá, Purús and Las Piedras basins), and habitat types: river channels, terra firme (non-floodplain) streams, and floodplain lakes. We present a robust, well-documented collection of fishes from the region including 272 species collected from 132 field sites over 63 field days and four years, comprising the most extensive collection of fishes from this region to date. We conduct a preliminary community phylogenetic analysis based on this...

A new species of Glaphyropoma: the first subterranean copionodontine catfish and the first occurrence of opercular odontodes in the subfamily (Siluriformes: Trichomycteridae)
Provedor de dados: 83
Autores: Bichuette,Maria Elina; Pinna,Mario César Cardoso de; Trajano,Eleonora.
A new species of the rare copionodontine genus Glaphyropoma is described from subterranean waters in the Diamantina Plateau, Bahia State, central northeastern Brazil. This is the first troglomorphic species in the subfamily Copionodontinae. It is distinguished from all other copionodontines by the presence of opercular odontodes, and further distinguished from its only congener, G. rodriguesi, by the reduction of dark integumentary pigmentation. The new species shares the single synapomorphy previously proposed for Glaphyropoma, the marked narrowing of the first hypobranchial and indirect character evidence also supports its inclusion in the genus. The presence of opercular odontodes in the new species, in combination with a reviewed hypothesis of sister...

Renewable natural resources (RNR) are a major source of socio-economic development potential in all developing countries, if they can be conserved, developed and sustainably exploited. For strategic conservation and sustainable exploitation strategies to be implemented, a knowledge of biodiversity at various levels within these RNR has to be investigated and documented in an internationally accepted manner, and preferably as close as possible to the habitat of the resources. However, human and material resources available in developing countries are currently neither sufficiently trained nor sufficient to undertake the appropriate studies. Meanwhile, various forces continue to deplete RNR and their inherent biodiversity. An attractive approach towards...

Biodiversity is a holistic concept which encompasses what the scientific literature describes as inter-specific diversity (diversity between species), intra-specific diversity (genetic diversity) and diversity of ecosystems. As a support of life, the preservation of biodiversity in terrestrial and marine habitats is of primary importance for the ecological balance of the Earth. Moreover, it is essential for human beings whose lifestyle depends on nature. The value of biodiversity lies with the opportunities provided to mankind to adapt to a changing environment. Concerning specifically the seas and oceans that constitute ¾ of the planet and 90% of the biosphere, there is a renewed ‘ecological awareness’ at the global level on the need to preserve marine...

Biodiversity of Estuarine Fish Faunas in West Africa
Provedor de dados: 20
Autores: Baran, E.
In West Africa (between Ivory Coast and Sénégal), estuarine environments vary from lagoons to high discharge rivers to inverse hypersaline estuaries. This results in a high diversity of estuarine fish species, with an important turnover and a core of ubiquitous species. The species richness of a given estuary depends on the combination of hydrological factors (marine or freshwater dominance) and biogeography (continental biogeographic regions). The catch rate is higher in lagoons and inverse estuaries than in normal estuaries, which can be explained by the predominance of small juveniles in the latter. Clupeids are the most abundant fishes all over the region, but different systems have different dominant species. Assessing the functioning of West-African...

Autores: Vega, M.; Rueda, M.; Valencia T., M.
La sensibilidad del medio ecológico Antártico obliga a conocer los diferentes niveles de contaminación de origen convencional y nuclear, con el fin de establecer posibles acciones tendientes a impedir que futuros accidentes e incidentes atenten contra sus ecosistemas. La evaluación de la concentración de Cs-137, como radionucleído gamma radiante, en agua, suelos y plantas, permite establecer la movilidad de este isótopo, considerando entre los más importantes elementos de contaminación originadas en los procesos de fisión nuclear. Se tomaron muestras de los tres medios anotados anteriormente, se las analizaron luego mediante espectroscopía gamma, encontrándose que en agua y en vegetales, los niveles de Cs-137 están por debajo de los límites de detección,...

Provedor de dados: 20
Autores: Aggrey-Fynn, J.; Sackey-Mensah, R.
The diversity and relative species abundance of fisheries resources were studied from Winneba to Cape Coast on the central coast of Ghana during December 2007 to May 2009. Samples of organisms were collected at random from beach seine landings during the study period. The fishes were counted and identified to the family and species levels. Ecological indices such as Shannon-Wiener diversity index, equitability and Sørenson’s similarity index were used to analyse the data. Specimens from Winneba, Saltpond and Cape Coast comprise 56 species belonging to 30 families. Carangidae, Haemulidae, Clupeidae and Sciaenidae were some of the families, where key species occurred during the study. The relative abundance of key organisms in the beach seine landings...

Autores: Entsua-Mensah, M.; Ofori-Danson, P.K.; Koranteng, K.A.
Coastal lagoons form an integral part of marine fisheries and provide important spawning and nursery grounds for many fish species. The economic contributions of lagoon fisheries have not been given adequate consideration by fisheries authorities. Ghana's 550-km coastline includes over 90lagoons. These lagoons and their wetlands provide valuable products and services, which include supporting the fisheries, absorbing floodwaters and protecting biodiversity. They also serve as roosting, nesting and feeding sites for many species of birds. Through the support of the World Bank and the Global Environmental Facility, Ghana has designated five coastal wetland areas as Ramsar sites due to their importance as fishing areas and as roosting, nesting and feeding...

International conferences, environmental campaigns and scientific studies have all advocated precautionary measures and remedies. 2. Humanity must take account of the amount of pressure the Earth can stand, and adopt lifestyles and development methods that respect nature’s limitations, without necessarily having to forgo the benefits of modem technologies. 3. Biosphere reserves are designed to respond to this dilemma. Their effectiveness hinges on synergy between scientists, conservation and development groups, management authorities and local communities. Such requirements are confirmed by the principles of...

The coastline of the island of Mauritius is 322 km long and is almost completely surrounded by fringing coral reefs enclosing a lagoon area totaling 243 km. The volcanic nature of the island's origin, the existence of coral reefs and the access to the lagoons of more than 50 rivers and rivulets, determine the diversity of the coastal habitats, flora and fauna. The island has several sandy beaches, protected bays and calm lagoons - factors that have favoured a prosperous tourism industry. Economically, the coastal zone is by far the most valuable segment of the Mauritian territory. Located here are the tourist facilities, secondary residences, ports, fisheries infrastructure and public beaches. Figure 3 gives the changes in coastal land distribution from...

Renewable natural resources constitute major sources for socioeconomic development of all developing countries, if they can be con-served, developed and sustainably exploited. For its strategic conservation and sustainable exploitation, biodiversity has to be investigated and documented at various levels and in an internationally accepted manner. However, the human and material resources available in the developing countries are insufficient to under-take the necessary studies, while various forces continue to degrade or erode biodiversity; The obvious solution is through collaboration in research and training.

The Case of South Africa

Autores: Wynberg, R.; Grundy, I.
South Africa is in general a dry country, where the vegetation cover is determined by its low mean annual rainfall. As a result most of the country is covered by dry savanna woodland or woodland scrub. Midgley et al (1997) define forests as being closed-canopy plant communities comprising mainly woody plants more than 5m tall and maintain that within this definition patches of forest occur within almost all southern African biomes. Most natural evergreen forests are found in areas of higher rainfall, however, in a narrow broken belt along the southern and eastern seaboard, and in the country’s mountainous regions towards the eastern borders with Swaziland and Mozambique (Figure1) (Low and Rebelo, 1996). Estimates of the area covered by closed canopy...

Tropical forest ecosystems have multiple functions and therefore are great significance for the well-being of people. It is widely acknowledged that forests and trees simultaneously provide a wide range of socio-economic and environmental benefits and values to humankind. They deserve conservation and wise use for the benefit of rural people who are dependent on these forests and for the benefit of humanity in general. Unfortunately, the use of tropical forests has been undertaken with little care about their potential to fulfil many functions and also about their future.

The Status and Interconnections of Selected Environmental Issues in the Global Coastal Zones: Problem of Increasing Vulnerability
Provedor de dados: 20
Autores: Shi, H.; Singh, A.; Foresman, T.; Fosnight, E.A.
This study focuses on assessing the state of population distribution, land cover distribution, biodiversity hotspots and protected areas in global coastal zones. The coastal zone is defined as land within 100 km of the coastline. This study attempts to answer such questions as: how crowded are the coastal zones, what is the pattern of land cover distribution in these areas, how many of these areas are designated as protected areas, and what is the state of the biodiversity hotspots. This study uses globally consistent and comprehensive geo-spatial data sets based on remote sensing and other sources. The application of modern Geographic Information System (GIS) layering methods and consistent data sets has made it possible to identify and quantify selected...

State of Biodiversity: Western Cape Province, South Africa Mammals
Provedor de dados: 20
Autores: Lloyd, P.H.
The Western Cape Province (W.C.P.) of South Africa, one of nine provinces forming the country, is generally regarded in South African terms as being “poor” with respect to the number of its mammals when compared to the other eight provinces. This misconception has its origin in the fact that the Western Cape, essentially a winter rainfall region, lies adjacent to one of the richest spots in the world in terms of mammalian diversity, namely the summer rainfall region of the rest of South Africa. In fact only when compared with the rest of our own country can the Western Cape be regarded as having a “poor” mammofauna in terms of biodiversity. However, some of the other Western Cape vertebrate and many of the invertebrate groups do reflect higher levels of...

Détermination fractale des types de cotes basée sur les systèmes d’informations géographiques : cas de la Tunisie
Provedor de dados: 20
Autores: Bel Hassen, M.; Azizi, M.
Les dimensions fractales des côtes tunisiennes ont été déterminées en utilisant les techniques spatiales fournies par les systèmes d’informations géographiques, en se basant sur une cartographie au 1 :100000 du trait côte. La dimension fractale des côtes tunisiennes est estimée à 1,0805. Une segmentation des côtes en trois parties (nord, est et sud) a permis de mettre en évidence une décroissance de la dimension fractale du nord vers le sud, indiquant que la complexité de la côte décroît vers les faibles latitudes. De nombreuses conséquences découlent de ces résultats, applicables à des stratégies d’échantillonnage, comme à la compréhension de l’écologie et  l’interprétation de la distribution des espèces et les modèles de biodiversité.

consumption needs of the population, it remains difficult to assure the continuity of national resources or to provide for protection of nature. The Convention of Biological Diversity has identified the need for Parties to integrate biodiversity with other sectors of the economy and civil society. Given that EIA is the only instrument available to ensure that consideration is accorded to environmental aspects in economic development plans, it is important that EIA should fully incorporate biodiversity considerations, to ensure that natural resources are taken into account in the development process.

Mangrove ecosystems on the coast of Cameroon are valuable both for their contributions to local livelihoods and the globally important biodiversity that they contain. However, these areas are threatened by a number of development pressures as well as unsustainable management and harvesting practices of the local communities living there. This project aims to strengthen protection and reduce degradation in these areas by supporting inter-sectoral co-ordination and collaboration (within an agreed national framework) and by helping local communities to redirect local economic activities towards activities that both improve their livelihoods as well as assist with the conservation of globally important biodiversity found in these areas.

Biodiversity, Trade, And The Fishing Sector Case Study: West Africa

Autores: Stone, C.D.; Downes, D.; de Fontaubert, A.C.
In 1997, IUCN-The World Conservation Union, with the financial support of the German Federal Ministry for Economic Co-operation and Development, initiated a project to examine the relationship between the Convention on Biological Diversity (CBD) and the rules of international trade–those administered by the World Trade Organisation (WTO), in particular. The project was motivated by a widely shared concern that the aims of the CBD, which are essentially to conserve and equitably distribute the benefits of the environment, might be undermined by the WTO, which aims at the liberalisation of trade. Liberalised trade has the potential to integrate economies, regionally and globally, in mutually beneficial ways. But some observers are concerned that it may do so...

Biodiversity and sustainable management of a tropical wetland lake ecosystem: A case study of Lake Kanyaboli, Kenya
Provedor de dados: 20
Autores: Rasowo, J.O.; Abila, R.; Manyala, J.
Lake Kanyaboli and the surrounding Yala swamp wetland has been recognized as an important biodiversity hotspot. Recent population genetic and phylogenetic studies confirm the evolutionary importance of Lake Kanyaboli (Kenya) in preserving the cichlid fish fauna of Lake Victoria. The adjoining Yala swamp harbours the endangered swamp antelope Sitatunga (Tragecephalus spekii) and several papyrus endemic birds. The lake and adjoining swamp play a critical role in the livelihood of the local communities who heavily depend on the wetland resources. Current ongoing large scale land use changes within the swamp threaten the ecological integrity and functioning of this highly dynamic wetland ecosystem. It is therefore imperative that proper management and...

Autores: Mironga, John Momanyi.
The paper presents data collected in an assessment of effects of water hyacinth infestation on phytoplankton productivity in Lake Naivasha, Kenya. A summary of the status of control and strategies for the future is given. The ecological effects of water hyacinth, Eichhornia Crassipes, on Lake Naivasha have received little attention compared to the large body of work available on the weed’s socioeconomic impact on the country’s water ways and methods for its removal. This study was conducted to determine if water hyacinth infestation in Lake Naivasha affects phytoplankton productivity. Several sampling stations were set up in the lake at sites where the floating mats of the weed were present and sites where the weed was absent. Phytoplankton chlorophyll-a...

The marine biodiversity of the western Indian Ocean and its biogeography: How much do we know?
Provedor de dados: 20
Autores: Richmond, M.D.
Prior to the 1960s the biota of the western Indian Ocean inshore marine habitats received scant attention from taxonomists resulting in a poorly known flora and fauna. Fortunately, over the last 40 years there have been considerable developments in the study of marine biodiversity in this region, both from regional scientists and by those based at institutions in Europe and elsewhere. This paper reviews the current status of taxonomic knowledge of the marine biodiversity of the western Indian Ocean, focusing on the macroflora and macrofauna of the intertidal and shallow subtidal environments. The taxonomy of many of the smaller and particularly the softer-bodied invertebrate taxa remains a challenge to specialists, and as a result these taxa continue to be...

This paper investigates the question of what influence human beings have had on biodiversity in the region of KwaZulu-Natal in South Africa. A historical analysis has been made of human impact on local ecosystems and species accompanied by statistics on the reduction of habitats and systems caused by urbanisation, cultivation, silviculture and state dams. The major causes of biodiversity loss are identified as being habitat destruction or modification and extractive utilisation. The most important problem is that the government of South Africa does not have an effective environmental management system to ensure wise decision-making. The result has been sectoral ministries empowered with the dual role of both exploiting and preserving natural resources. In...

A Simple Non-Parametric Gis Model For Predicting Species Distribution: Endemic Birds In Bioko Island
Provedor de dados: 20
Autores: Fa, J.E.; Lenton, S.M.; Del Val, J.P.
Species mapping is a useful conservation tool for predicting patterns of biological diversity, or identifying geographical areas of conservation significance. Mapping can also improve our understanding of the appropriateness of habitat areas for individual species. We developed a new model, PREDICT, for mapping habitat suitability of plant and animal species from incomplete field survey data. PREDICT is a statistical program written for use within a GIS (geographic information system). It produces images and statistics that assess the potential of unstudied areas for wildlife for which presence/absence data and basic habitat information are available. Suitability for a target species is determined within surveyed and non-surveyed squares by a form of...

El análisis de largo plazo de las pesquerías costeras de Uruguay sugiere que el estado de  los principales recursos es preocupante. Esto puede deberse a múltiples causas (sobrepesca, polución, causas naturales), a lo cual se suman fallas en el diseño (e.g. información de base insuficiente) o en la implementación de las normativas vigentes (e.g. fiscalización), así como a la ausencia de un enfoque integrado. Este libro plantea estrategias para el desarrollo e implementación del Manejo Ecosistémico de Pesquerías (MEP) costeras de Uruguay. En este contexto, se hace especial énfasis en la identificación de Áreas Marinas Protegidas (AMPs) como herramientas de manejo pesquero y conservación de la biodiversidad de la costa uruguaya.

Autores: Ngoile, M.
Coral reef ecosystems are under increasing natural and anthropogenic pressures, despite their ecological significance and economic importance to mankind. The majority of land based activities and direct human use are borne by these shallow water areas, which interface between land masses and the open oceans. The objective of this paper is to give an overview of the value of coral reef ecosystems and the anthropogenic threats imposed on them, as well as to examine the interactions of coral reef ecological linkages to other coastal and marine habitats and the future of coral reef ecosystems. It is suggested that management measures for the preservation of reef systems must link coastal and marine systems, pay attention to socio-economic factors as well as...

In the recent past, there has been talk about the forest as a future challenge and as a consequence of sustainable development. Regarding biodiversity in the Democratic Republic of Congo (DRC), the forest issue comes up not only as recognition for its rich and complex forest cover, but also to show that it is from these forest biological resources that the population derives its basic economic needs, notably products from gathering, hunting, construction materials, medicinal plants, firewood, wine and cola nuts, etc.

Autores: Diarra, Bassirou.
La pêche au Sénégal joue un rôle économique et social très important par une contribution globale de près de 11% du PIB primaire et 2,3% du PIB total. Elle occupe de façon directe et indirecte environ 600 000 personnes, soit près de 17% de la population active selon la DP M. Cependant ces dernières décennies, les études ont montré que le secteur traverse une crise aiguë se traduisant par une raréfaction croissante des ressources, notamment les espèces nobles qui ont une forte valeur commerciale. Cette crise est due entre autres à une surexploitation de ces ressources qui est le résultat d’un manque de maîtrise de l’effort de pêche surtout pour les pêcheries artisanales (80% des débarquements et plus de 60% des approvisionnements des industries de la place)...

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: Van den Bergh, E.; Huiskes, A.; Criel, B.; Meire, P.
The tidal marshes along the Scheldt estuary are rather unique in Europe, because they still exist along the complete salinity gradient. Key ecological factors for the vegetation are salinity, tidal regime and current and historical management. A general portrait with the most characterising plant species as well as a succession scheme are presented for salt, brackish and fresh tidal marshes separately, because they have few plant species and vegetation types in common. Tidal regime changes as a combined effect of sea level rise and the channel deepening in the Westerscheldt. This affects the marsh vegetation. Biodiversity patterns and factors affecting the distribution of species on the tidal marshes are discussed for plants, gastropodes, arthropodes and...

It is important to have a statistically robust forest information data base which can be updated and can provide long-term information. National Forest Inventories (NFI) provide one of the best large-scale sources of information, and therefore are a cornerstone of forest policies. The scopes of NFIs, which are the primary source of data for national and large-area assessments, has been broadened to include new variables to meet increasing information requirements. This paper describes the history, methodology and guidance of Spanish NFI and international requirements. The current objectives are determined by analysing future perspectives and possible direction of future assessments. These objectives include harmonization of NFI, open data source and to...

The success in the process of restoration and maintenance of the dynamics of an ecosystem is highly dependent on the capacity of species to promote interspecific interactions among the various life forms. These interactions create a favorable environment for the ecological restoration of degraded ecosystems. Thus, by review the literature, the objective of this study is to report the contribution and use of different animal groups in carrying out ecological restoration projects in Brazil. The fruit-eating birds and mammals and also other animals such as reptiles, fish and insects have been highlighted as tools to aid environmental ecological restoration projects. Techniques for attracting animals and consequent arrival of seedlings in a degraded ecosystem...

ABSTRACT Deforestation has negative impacts on diversity and community patterns of several taxa. In the eastern Amazon, where much deforestation is predicted for the coming years, forests patches may be essential to maintain the local biodiversity. Despite increasing concerns about the conservation of threatened areas, few studies have been performed to analyze the communities of diversified groups, such as insects, in the eastern Amazon. Here, we investigated species diversity and community structure of fruit-feeding butterflies, a well-known bioindicator group, in a threatened remnant of an eastern Amazonian forest located on Maranhão Island, northeastern Brazil. Fruit-feeding butterflies were sampled monthly for one year. Diversity and evenness indices,...

Due to a suggestion that human areas add species to beta-diversity, we verified that up to 79 species now present have perhaps "invaded" with human activity (and 10 others are likely to invade), a total similar to that for lost species. However, lost species are often rare and invading species often widespread, resulting in exchange of "Picassos for Coca-Cola bottles." Furthermore, gains exceed losses only when large biological reserves are present, as in the...

A new species of Corydoras Lacépède (Siluriformes: Callichthyidae) from the Rio Tapajós basin and its phylogenetic implications
Provedor de dados: 84
Autores: Espíndola,Vinicius C.; Spencer,Marcelo R.S.; Rocha,Leandro R.; Britto,Marcelo R.
A new species of Corydoras is described from tributaries of the rio Arinos, rio Teles Pires and rio Preto, all in the rio Tapajós basin. The new species is a member of a group that includes 36 species with spots on the body. Within this group, the new species can be readily distinguished by having a smaller dorsal-fin spine than the first three subsequent soft dorsal-fin rays; pectoral, pelvic and anal fins hyaline; dorsal-fin interradial membrane hyaline; rounded spots on trunk restricted to dorsolateral body plates and dorsal portion of ventrolateral body plates, not reaching the base of pelvic and anal fins. The new species can be further distinguished from Corydoras xinguensis by having spots with diffuse edges, and from all other species of spotted...

Autores: Tosetto,Everton Giachini; Neumann-Leitão,Sigrid; Nogueira Júnior,Miodeli.
Abstract Specimens of Pegantha laevis H.B. Bigelow, 1909 and Pegantha triloba Haeckel, 1879 were found in oceanic waters off the northern Brazilian coast. The former species is clearly distinct due to the thickness and shape of peripheral channels, while the latter is recognized mainly due to the exumbrellar furrows and long otoporpae. This study represents the first actual record of P. laevis inside the Brazilian Economic Exclusive zone, since previous reports were far away from the coast, and clarifies the presence of P. triloba off Brazil.

ADVANCES ON DIPTEROLOGY IN THE 21 ST CENTURY AND EXTINCTION RATES
Provedor de dados: 84
Autores: SANTOS,DAUBIAN; SAMPRONHA,STEPHANIE; SANTOS,CHARLES MORPHY DIAS.
ABSTRACT At least one million extant insect species have been described on Earth, of which 150,000 belong to the megadiverse order Diptera. We here synthesize data from the last 15 years of taxonomic work in Diptera, mapping the world taxonomic productivity in the order. Our data shows an increasing importance of China and Brazil in taxonomic production, along with other traditional centres such as the USA and Europe. We correlate our database with estimates of extinction rates to determine the amount of basic taxonomic research still necessary to have the description of the fly diversity before extinction. Due to the growing recent extinction rates, it is unlikely that we will be able to entirely describe unknown fly diversity before their demise. Even...

Soil macrofauna under integrated crop-livestock systems in a Brazilian Cerrado Ferralsol
Provedor de dados: 86
Autores: Marchão,Robélio Leandro; Lavelle,Patrick; Celini,Leonide; Balbino,Luiz Carlos; Vilela,Lourival; Becquer,Thierry.
The objective of this work was to assess the effects of integrated crop-livestock systems, associated with two tillage and two fertilization regimes, on the abundance and diversity of the soil macrofauna. Four different management systems were studied: continuous pasture (mixed grass); continuous crop; two crop-livestock rotations (crop/pasture and pasture/crop); and native Cerrado as a control. Macrofauna was sampled using a modified Tropical Soil Biology and Fertility method, and all individuals were counted and identified at the morphospecies level for each plot. A total of 194 morphospecies were found, distributed among 30 groups, and the most representative in decreasing order of density were: Isoptera, Coleoptera larvae, Formicidae, Oligochaeta,...

Why should we care about soil fauna?
Provedor de dados: 86
Autores: Anderson,Jonathan Michael.
The reasons why we care about soil fauna are related to their intrinsic, utilitarian and functional values. The intrinsic values embrace aesthetic or moral reasons for conserving below-ground biodiversity. Unfortunately, the protection of soil invertebrates has rarely been a criterion for avoiding changes in land use and management. Utilitarian, or direct use values, have been investigated more extensively for fungi, bacteria and marine invertebrates than for soil fauna. However, some traditional remedies, novel enzymes and pharmaceutical compounds have been derived from earthworms, termites and other groups, and gut symbionts may provide microbial strains with interesting properties for biotechnology. The functional importance of soil invertebrates in...

An important study in species of the genus Eupatorium, that inhabits other parts of the world, was conducted in the search for new molecules with pharmacological activities, thus showing that it is a potential source of novel secondary metabolites. We reviewed the number of Eupatorium species that have been described in the State of Michoacan, and that can be available for harvesting, to make a phytochemical screening. It was found that 69 Eupatorium spp are growing in 69% of the Michoacan territory. Within this group there are ten species used in Mexican traditional medicine. It was evident the difficulty in taxonomic classifying these species since several Eupatorium spp have synonyms. It appeared that the number of native members should be reduced in...

Autores: Sanchirico,   James N.
Over 300 natural scientists in 53 nations are taking part in the Census of Marine Life (CoML) to investigate what lived, what lives, and what will live in the oceans. The CoML is a scientific experiment that is exploring the limits of ocean science. The paper discusses the potential applications of CoML research and the mechanisms by which the potential benefits can be measured and preserved. I recommend developing and integrating policy advisory committees with the natural science activities to both maximize the benefits of the research and to avoid unintended consequences.

A Spatial-Intertemporal Model for Tropical Forest Management Applied to Khao Yai National Park, Thailand
Provedor de dados: 31
Autores: Albers,   Heidi J.
This paper discusses the application of a spatial-intertemporal model for tropical forest management to Khao Yai National Park in Thailand. This type of model, especially the spatial components, finds different optimal land allocations than do traditional models at empirically relevant levels of benefits. The spatial analysis here suggests that most of this park can be best used as a preserved area and also provides support for expanding the park into an adjacent unpopulated area. The analysis demonstrates that the park's benefits to regional agriculture and villagers are large enough that preservation can proceed without international support, and that local people, as a group, have incentives to maintain most of the area as preserved land. Although the...

Spatially explicit farming system modelling for an efficient agri-environmental policy design
Provedor de dados: 31
Autores: Havlik,   Petr; Bamiére,   Laure; Jacquet,   Florence; Millet,   Guy.
A mathematical programming model is developed and associated to a spatial pattern index (Ripley L-function) to analyse the optimal reserve design and implementation for the Little Bustard conservation in Plaine de Niort. The model structure corresponds to three spatial levels, fields, farm and landscape. Simple in terms of area representation it is detailed in term of farm behaviour and spatially explicit. The model is applied in a normative and in a positive way. The major findings of the normative approach relate to the trade-offs between the reserve pattern and its cost. It was found that the environmentally optimal reserve, which is randomly dispersed across the zone, is the most costly one. Within the positive approach, it is illustrated that the...

Where the rubber hits the road: Biodiversity conservation incentives in theory and practice
Provedor de dados: 31
Autores: Coggan,   Anthea; Whitten,   Stuart M.; Bennett,   Jeffrey W.
The lack of appropriate incentives through conventional markets is a major cause of deterioration of biodiversity on private land. In response, governments often intervene through changing the incentives faced by landholders. There are, however, potentially many ways that the incentives to private landholders could encourage improved conservation of native vegetation on private lands. These policies and incentives leverage change in different ways and are suited to differing opportunities and objectives and incur different costs. Our goal in this paper is to provide some guidance to support incentive selection and design decisions. We initially develop a framework for incentive decision, design and implementation. The framework is supported and illustrated...

Combining revealed and stated preference methods to assess the private value of agrobiodiversity in Hungarian home gardens
Provedor de dados: 31
Autores: Birol,   Ekin; Kontoleon,   Andreas; Smale,   Melinda.
Hungarian home gardens are small-scale farms managed by farm households using traditional management practices and family labor. They generate private benefits for farmers by enhancing diet quality and providing food when costs of transacting in local markets are high. Home gardens also generate public benefits for society by supporting long-term productivity advances in agriculture. In this paper, we estimate the private value to farmers of agrobiodiversity in home gardens. Building on the approach presented in EPTD Discussion Paper 117 (2004), we combine a stated preference approach (a choice experiment model) and a revealed preference approach (a discrete-choice, farm household model). Both models are based on random utility theory. To combine the...

RESOURCE EXPLOITATION, BIODIVERSITY AND ECOLOGICAL EVENTS
Provedor de dados: 31
Autores: Tsur,   Yacov; Zemel,   Amos.
We study the management of a natural resource that supports ecosystems as well as human needs.  The reduction in the resource base poses a threat of occurrence of catastrophic ecological events, such as the sudden collapse of the natural habitat, that lead to severe loss of biodiversity.  The event occurrence conditions involve uncertainty of various types, and the distinction among these types affects the optimal exploitation policies.  When uncertainty is due to our ignorance of some aspects of the underlying ecology, the isolated equilibrium states characterizing optimal exploitation for many renewable resource problems become equilibrium intervals, giving rise to hysteresis phenomena.  Events triggered by genuinely stochastic environmental conditions...

Towards a cost-effectiveness analysis of the measurement of biodiversity indicators
Provedor de dados: 31
Autores: Targetti,   Stefano; Viaggi,   Davide; Cuming,   David.
A comprehensive quantification of biodiversity in farming systems would require a very significant amount of work (and funds) even for a small area. Therefore, biodiversity indicators are needed to solve the problem of the measurement feasibility. Even though the issue of cost and effectiveness is central for the evaluation of the indicators, only the latter is discussed in detail in the scientific literature. This work presents a cost analysis based on the direct gathering of records from a farm-scale biodiversity survey (EU-FP7, BioBio - “Indicators for biodiversity in organic and low-input farming systems”) where the analysis of costs is part of the project. It is a simple method for comparing different indicators by their ratio of cost/effectiveness....

Private Research and Public Goods: Implications of Biotechnology for Biodiversity
Provedor de dados: 31

The pattern of crop genetic diversity has changed over the past two centuries with the modernization of agriculture, accelerating with the advent of the green revolution. Since the green revolution, the locus of agricultural research has shifted from the public to the private sector. The growing importance of the private sector in agricultural R&amp;D is changing the types of crop technologies that are developed and the ways they are delivered to farmers. The spread of transgenic crops will influence crop genetic diversity, but their implications for the availability of plant genetic resources and the resilience of agricultural ecosystems are not entirely clear. Transgenic crops may increase or decrease crop genetic diversity, depending on how they are...

Property rights of landholders in non-captive wildlife and prospects for conservation
Provedor de dados: 31
Autores: Tisdell,   Clement A.
In order to reduce the rate of human-induced biodiversity loss of wild species, it has become increasingly important to stem this loss on private and tribal lands and to find effective policies to do this.  Some writers believe that granting landholders commercial property rights in wildlife might be effective in dealing with this matter and result in the sustainable use of wildlife.  This paper explores this view using economic theory.  In doing so, it takes into account the total economic valuation concept.  While granting of commercial property rights is found to be effective for conserving some species, it is predicted to be a complete failure as a means of conserving other species.  In addition, particular attention is given to the economics of the...

Valuation of Linkages between Climate Change, Biodiversity and Productivity of European Agro-Ecosystems
Provedor de dados: 31
Autores: Palatnik,   Ruslana Rachel; Nunes,   Paulo A.L.D.
It is clear that climate change involves changes in temperature and precipitation and therefore directly affects land productivity. However, this is not the only channel for climatic change to affect agro-systems. Biodiversity is subject to climatic fluctuations and in turn may alter land productivity too. Firstly, biodiversity is an input into agro-ecosystems. Secondly, biodiversity supports the functioning of these systems (e.g. the balancing of the nutrient cycle). Thirdly, agro-systems also host important wildlife species which, though not always, play a functional role in land productivity, nonetheless constitute important sources of landscape amenities. The present paper illustrates a unique attempt to economically assess this additional effect...

Investments in Biodiversity Prospecting and Incentives for Conservation
Provedor de dados: 31
Autores: Sedjo,   Roger A.; Simpson,   R. David.
There is considerable interest in biodiversity prospecting (the search for valuable new products from natural sources) as a conservation strategy. In an earlier paper, we have argued that the value of the marginal species (and, by extension, the incentives for the conservation of the habitat on which it is found) is small. In this paper, we show that investments in biodiversity prospecting are unlikely to increase incentives for conservation by much. If the value of the marginal species were appreciable, researchers ought already to have made investments to exploit it. If it is not, it is doubtful that additional investments will generate any substantial increase. It is important to be clear about our findings: we are not saying that none of the myriad...

The Value of Backyard Biodiversity in New Zealand
Provedor de dados: 31
Autores: Parminter,   Terry G.; Kaval,   Pamela; Yao,   Richard T.; Scrimgeour,   Frank G.
New Zealand's biodiversity consists of over 80,000 types of native plants, animals and fungi, a considerable number of which are indigenous and located on private property. To preserve and enhance native biodiversity and discourage activities that may deplete it, economic values can be calculated which can, in turn, guide the use of policy tools, such as incentives, that can be used. This can support behavioural changes by encouraging individual self-interest to coincide with social interest. In this project, we used the contingent valuation, choice modelling and well-being approaches to estimate native biodiversity values for Wellington residents. In this paper, we present a summary of our initial results.

Sustainable Agriculture

Autores: Tisdell,   Clement A.
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...

Biodiversity measurement is necessary to evaluate conservation alternatives and understand how to maximize biodiversity returns on conservation budgets. In the economics literature, most studies focus on species level diversity. Existing measures based on species' pairwise genetic differences do not perform optimally. This paper develops two new biodiversity measures within the same genetic framework. An axiomatic diagnosis for this class of measures is proposed and four biodiversity measures are then compared. Though the axiomatic comparison points towards a single "best" measure, it also indicates that the choice of measure should be dependent on the conservation problem at hand.

Exploring the cost effectiveness of land conservation auctions and payment policies
Provedor de dados: 31
Autores: Connor,   Jeffery D.; Ward,   John R.; Bryan,   Brett.
This article evaluates the cost-effectiveness of the Catchment Care Australian conservation auction. It provides evidence of auction cost effectiveness, and estimates cost savings from two discrete components: (i) the opportunity cost revelation incentive provided by the auction mechanism, and (ii) the improved environmental targeting capacity that results from development of a scientifically based environmental benefits assessment capacity. Results show that there are potentially very large returns associated with the latter component that have been overlooked in the literature. Additionally, transaction costs involved with administering the case study conservation auction and the prior non-auction payment policy are compared. We find that the...

Multifunctional Agriculture: A Framework and Policy Design
Provedor de dados: 31
Autores: Lankoski,   Jussi E.; Ollikainen,   Markku.
We study the multifunctional character of agriculture in a model of endogenous input use and land allocation augmented by biodiversity, landscape amenity, and nutrient runoff. While biodiversity and landscape amenities represent the public good aspects of agriculture, nutrient runoff represents its negative externalities. We show that the private use of fertilizer input is higher and the size of buffer strips lower than the socially optimal solution requires. Also the socially optimal land allocation differs from the private solution due to the valuation of landscape diversity and runoff damages. The optimal policy is to use a differentiated fertilizer tax and a differentiated buffer strip subsidy and to determine their levels by the equality between the...

Valuing Ecosystem Diversity in South East Queensland: A Life Satisfaction Approach
Provedor de dados: 31
Autores: Ambrey,   Christopher L.; Fleming,   Christopher M.
The life satisfaction approach has recently emerged as a new technique in the suite of options available to non-market valuation practitioners. This paper examines the influence of ecosystem diversity on the life satisfaction of residents of South East Queensland, Australia. It is found that, on average, a respondent is willing-to-pay approximately AUD$20,000 in household income per annum to obtain a one-unit improvement in ecosystem diversity. This result indicates that the life satisfaction effects of improvements in ecosystem diversity are substantial, and greater than the welfare effects implied by studies using more conventional non-market valuation techniques.

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...

Autores: Chiabai,   Aline; Travisi,   Chiara M.; Ding,   Helen; Markandya,   Anil; Nunes,   Paulo A.L.D.
By using ad hoc value transfer protocols, this paper offers a methodological contribution and provides accurate per hectare estimates of the economic value of some selected ecosystem services for all forest biomes in the world, identified following the Millennium Ecosystem Assessment taxonomy MEA. The research also estimates potential total economic losses from policy inaction in year 2050. Final results show that total losses are significant. The total figure is €78 billion, the greatest losses coming from North America and Mexico, followed by Africa, Russia and some Asiatic countries. Most of this loss is attributable to provisioning services and carbon sequestration, while only a minor part is due to loss of cultural services. In terms of biomes the...

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...

The voracious appetites of public versus private property: a view of intellectual property and biodiversity from legal pluralism
Provedor de dados: 31
Autores: Wiber,   Melanie G.
In an opening vignette to an otherwise insightful article, Carol M. Rose (2003) compares people who hold intellectual property rights to poor villagers in India. They put effort and time into developing small but productive properties, only to have the wild tiger or rogue elephant of the public domain trample them or eat them up. In extreme cases, IP "villages" are abandoned and left to "the jungle" of public property. But Rose neglects another part of the story, and that is that the villagers are also hungry, and while they do not directly consume tigers, they do consume the environment a tiger needs to survive. This paper argues, from the perspective of legal pluralism, that both private and public properties are voracious. In recent western...

Autores: Roeder,   Norbert; Lederbogen,   Dirk; Trautner,   Juergen; Bergamini,   Ariel; Stofer,   Silvia; Scheidegger,   Christoph.
The following paper assesses the impact of different policy options on the land use and associated biodiversity values of jointly organized low intensity grazing systems (‘Allmende’) in Southern Bavaria. We use an integrated economic and ecological modelling approach to compare the results of the scenarios with a reference situation that reflects the Common Agricultural Policy prior to the Fischler Reform. The economic sub model is based on single farms which alter their land use in response to economic stimuli. Within the economic part, key factors like the farm’s endowment with machinery, quota and buildings but also the farmer’s attitude are regarded. Within the rule based ecological sub model we analyze three main parameters: (a) protected habitats...

Agricultural Sustainability and the Introduction of Genetically Modified Organisms (GMOs)
Provedor de dados: 31
Autores: Tisdell,   Clement A.
In order to cater for the predicted growth in global population and aspirations for increased living standards, the world needs to increase substantially its level of agricultural production and sustain agriculture’s increased productivity. New technologies may enable this to occur but they also bring with them increased sustainability problems. There are many complex dimensions to achieving agricultural sustainability such as deciding on what agricultural attributes are worth sustaining and considering what trade-offs in objectives are required. These issues are discussed from a conceptual point of view. It is also shown using economic theory that market-based agriculture limits the opportunity for individual farmers to adopt sustainable agricultural...

Economics, Ecology and GMOs: Sustainability, Precaution and Related Issues
Provedor de dados: 31
Autores: Tisdell,   Clement A.
Ecological, evolutionary and economic issues involved in introducing genetically modified organisms (GMOs), mainly in agriculture, are discussed. The ecological and evolutionary impacts identified hamper (economic) valuation of GMOs and their biosafety regulation and creates difficulties for planning for sustainable development. Assessment of the desirability of releasing GMOs is difficult because of lack of communal agreement about the risks involved, about how much precaution should be exercised given collective risks, and disagreement on the appropriate social criterion to apply. Changes in legal liability are not always economic and cannot eliminate the social conflict generated by GMOs. The economics of developing and marketing GMOs is explored,...

Marginality and Restoration of Olive Plantations in Andalusia
Provedor de dados: 31
Autores: Arriaza Balmón,   Manuel; Guzman,   Jose R.; Nekhay,   Olexandr; Gomez-Limon,   Jose Antonio.
This paper presents the first results of the initial stages of a three years research project on optimization of the use of agricultural lands subject to risk of abandonment. After devising a physical marginality index for olive cultivation based on soil quality and slope, we estimate an approximate area of 200,000 hectares of marginal olive plantations in Andalusia. The risk of abandonment of these farmlands increases with the decoupling of the CAP subsidies and with the socio-economic characteristics of the production. The probable abandonment of these areas implies the negative consequences of wild forestation. We present some actions to minimize the negative effects of this process, being the use of grass cover and hedgerows, on an initial qualitative...

Economics, Ecology and the Development and Use of GMOs: General Considerations and Biosafety Issues
Provedor de dados: 31
Autores: Tisdell,   Clement A.
This article outlines both ecological and socioeconomic issues involved in the development and use of GMOs. It’s argued that while initially new GMOs add to the global stock of biodiversity, in the long-term they result in a decline in biodiversity. Various mechanisms that bring about this decline in genetic diversity are identified. It is suggested that due to evolutionary forces, the desirable genetic properties of some GMO may be eroded in the long-term. They are unlikely to be sustained in their ecological effectiveness forever. The economics of developing and marketing of GMOs is given particular attention. When their development is left to private enterprise, it is found that the economics of developing and marketing GMOs favours large enterprises as...

Discusses generally why humans should bother to conserve sea turtles. In doing so, it considers both economic and non-economic reasons and outlines threats to the existence of sea turtles and ways in which tourism may either contribute to the conservation or decline of their populations. Turtle-based ecotourism at Mon Repos in southern Queensland is described. As a result of a survey conducted by the authors, it is shown that turtle-based ecotourism at Mon Repos has positive social (indirect) consequences for the conservation of sea turtles. Furthermore, it is argued that ecotourism operations at Mon Repos have positive direct impacts on the sustainability of populations of sea turtles. However, using a simple model, it is demonstrated that this impact is...

Establishing a benefits transfer database for biosecurity decision making an indigenous biodiversity
Provedor de dados: 31
Autores: Bell,   Brian A.; Cudby,   Charlotte; Yap,   Michael.
An imbalance of quantitative information on pest and disease impacts hampers biosecurity decision-making; there is relatively good information about impacts on industry, but relatively poor information about how society values the impacts on indigenous biodiversity. A benefits transfer process based on a database of choice experiments could help to redress this imbalance. This paper: briefly reviews four choice experiments that will be the foundation of a database; reviews benefit transfer literature; and sets out framework ideas for a Decision Support System (DSS), which will incorporate biodiversity values via a process for benefit transfer to facilitate more informed biosecurity decisions.

Néhány évtizeddel ezelőtt a vidék és a mezőgazdaság fő feladata az volt, hogy elegendő mennyiségű és megfelelő minőségű élelmiszert és ipari alapanyagot állítson elő, hatékonyan foglalkoztatva a vidéki népesség jelentős hányadát. Később felmerült, hogy csökkenteni kellene az agrárium okozta környezeti terhelést, elsősorban a vegyszerfelhasználást minimalizálva. Ebből a törekvésből fejlődött ki a ma már az egész fejlett világban sikeres biotermesztés, ökológiai gazdálkodás. A század- és ezredfordulón azonban új, sokkal diverzifikáltabb igények is megjelentek; a klímaváltozást előidéző gázok kibocsátás-csökkentésétől a helyi termékek fogyasztásáig, az élelmiszer-biztonságtól a szegény országok megsegítéséig.

Impacts of Population and Income Growth Rates on Threatened Mammals and Birds
Provedor de dados: 31
Autores: Pandit,   Ram; Laband,   David N.
Per capita income and human population levels in a country have direct influences on its environmental outcomes. Countries with same level of income may have different rate of income growth and vice versa, suggesting that the influence of the rate of income growth on environmental outcomes could be different than that of income level. Similarly, the rate of population growth might have different impact in addition to the impacts of sheer number of population. We explore this empirical question using country-level data on threatened species published by IUCN for the year 2007. Controlling for other factors, our model estimates the influences of the rate of population and income growth on threatened mammals and birds across 113 continental countries. The...

Most advances have been made in the major millet crops, sorghum and pearl millet, as compared to finger millet and other minor millet crops, which in many ways dependent on local markets for seed purposes. In this study, we have analyzed the evolving interactions between formal systems related to the delivery of modern varieties and informal systems for maintaining traditional seeds in the semi-arid regions of India. It is evident that in these marginal environments, crop and variety use decisions, and the crop biodiversity levels take place within the context of local seed markets and a national seed industry.

Bioeconomic Analysis of Aquaculture's Impact on Wild Stocks and Biodiversity
Provedor de dados: 31
Autores: Tisdell,   Clement A.
Anderson theorizes that development of the aquaculture of a species of fish (also captured in an open-access fishery) favours the conservation of its wild stocks, if competitive market conditions prevail. However, this theory is shown to be subject to significant limitations. While this is less so within his model, it is particularly so in an extended one outlined here. The extended model allows for the possibility that aquaculture development can impact negatively on wild stocks thereby shifting the supply curve of the capture fishery, or raise the demand for the fish species subject both to aquaculture and capture. Such development can threaten wild stocks and their biodiversity. While aquaculture development could in principle have no impact on the...

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...

The Farmers' Plea to Environmentalists

Autores: Avery,   Dennis T.
This paper critically examines linkages between alternative farming practices and environmental quality. Environmental impacts of high-yield farming are contrasted to those of low-yield farming. Traditional low-yield farming systems, while being promoted by environmental groups, have resulted in massive famine, higher cancer rates, soil erosion, and losses in wildlife habitat. Organic farming and other low-yield systems are land intensive and invade marginal farmland, thereby destroying wildlife habitat and biodiversity. Low-yield farming has not and cannot produce enough food to meet the food needs of the world’s population. By contrast, high-yield farming minimizes land use for food production and increase the availability of land for wildlife habitat...

This paper presents an optimal control model to analyze reforestations with two different species, including commercial values, carbon sequestration and biodiversity or scenic values. We solve the model qualitatively with general functions and discuss the implications of partial or total internalization of environmental values, showing that internalizing only carbon sequestration may have negative impacts on biodiversity-scenic values. To evaluate the practical relevance, we compare reforestations in the South-west of Spain with cork-oaks (a slow growing native species) and with eucalyptus (a fast growing alien species). We do the analysis with two different carbon crediting methods: the Carbon Flow Method and the Ton Year Accounting Method. With the...

Lamington National Park in Queensland, Australia is noted for its rainforest and is part of Australia’s fourteen World Heritage listed properties but no systematic study has been done of the importance of birds to its visitors.  This study rectifies this situation.  It is based on data from survey forms handed to visitors at an important site in this park and completed by visitors following their visit.  This yielded 622 useable replies.  These enabled us to establish the comparative importance of birds as an attraction to this site. Furthermore, logit regression is used to analyze 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 various...

In this paper we present a systematic attempt to assess economic value of climate change impact on forest ecosystems and human welfare. In the present study, climate change impacts are downscaled to the different European countries, which in turn constitute the elements of our analysis. First, we anchor the valuation exercise in the Millennium Ecosystem Assessment (MEA) Approach and therefore the link between the different forest ecosystem goods and services, including provisioning, regulating and cultural services, human well-being and climate change. Second, climate change is operationalized by exploring the different storylines developed by the International Panel on Climate Change (IPCC) and applied, downscaled, for each of the European countries under...

We develop a general framework for multifunctional agriculture, which includes not only public goods but also rural viability as a non-public good item. We contribute to the literature in two ways. First, we demonstrate how the broader definition of multifunctional agriculture differs from the agri-environmental multifunctionality, and how agri-environmental policy should be reformed to include these aspects. We show that rural viability entails adjusting fertilizer tax and buffer strip subsidy below their first-best Pigouvian levels to reflect the direct and indirect employment effects of agricultural production. Moreover, we show that when non-agricultural land use is present, an additional, non-agricultural instrument is needed to adjust the amount of...

The hidden economy surrounding the medicinal plant trade in South Africa is estimated to be worth approximately $60 to $100 billion per annum. There is increasing focus on the role that these resources play in the process of sustainable development. By combining Local Economic Development (LED), incentive structures and resource management systems strategies in the Eastern Cape, biodiversity degradation can be potentially decreased in line with community development goals. Qualitative data comparisons are used to assess the extent of the success of this holistic approach to development using the Umthathi Africulture Project as a case study.

A Global Land Use and Biomass Approach to Reduce Greenhouse Gas Emissions, Fossil Fuel Use and to Preserve Biodiversity
Provedor de dados: 31
Autores: Riedacker,   Arthur.
As average growth consumptions per capita and world population will continue to grow, the promotion of sustainable developments during the next half a century implies to take into account environmental aspects, local potentialities and futures changes in population as well climatic, economic and social factors. At the global level, land and fossil fuel availability per capita, capacity of absorption of greenhouse gas emissions are considered the most important environmental factors. Whereas at local levels are to be considered preservation or improvement of soil fertility, of water regimes, of quality of air, soil and water. Biodiversity must be taken into account at both levels to cope also with climate change. But as underlined by IPCC lead authors, up...

Biodiversity Valuation in Developing Countries: A Focus on Small Island Developing States (SIDS)
Provedor de dados: 31
Autores: Teelucksingh,   Sonja S.; Nunes,   Paulo A.L.D.
The Millennium Development Goals explicitly recognise “sustainable development” as a target. A step towards this is a greater understanding of the significant role of biodiversity in rural communities of developing countries who depend most on the ecosystem goods and services and who as a result may suffer most from its continued degradation. Understanding the input of biodiversity in developing countries to the provision of the ecosystem goods and services (EGS) that are essential to their human well-being is seen as a significant first step in sustainable development, and environmental valuation is a necessary tool for achieving this objective. However, valuing biodiversity in a developing country context can be an intricate affair. While economic...

Spatially explicit farming system modelling for an efficient agri-environmental policy design
Provedor de dados: 31
Autores: Havlik,   Petr; Bamiére,   Laure; Jacquet,   Florence; Millet,   Guy.
A mathematical programming model is developed and associated to a spatial pattern index (Ripley L function) to analyse the optimal reserve design and implementation for the Little Bustard conservation in Plaine de Niort. The model structure corresponds to three spatial levels, fields, farm and landscape. Simple in terms of area representation, it is detailed in terms of farm behaviour and spatially explicit. The model is applied in a normative and in a positive way. The major findings of the normative approach relate to the trade-offs between the reserve pattern and its cost. It was found that the environmentally optimal reserve, which is randomly dispersed across the zone, is the most costly one. Within the positive approach, it is illustrated that the...

Allocating Conservation Resources under the Endangered Species Act
Provedor de dados: 31
Autores: Langpap,   Christian; Kerkvliet,   Joe.
The necessity to develop a priority system to guide the allocation of resources to the conservation of endangered species is widely recognized. The economic theory of biodiversity has established a framework to do so, and has identified priority criteria that should be considered when making conservation decisions. This paper uses a random effects ordered probit model of endangered species recovery to simulate the effects of reallocating conservation funds among species listed under the Endangered Species Act according to these criteria. Our results suggest that if the goal of conservation policy is to preserve a diverse set of species, reallocating conservation funds according to criteria identified by economic theory would yield an improvement over...

The Effect of Market Development On-farm Conservation of Diversity of African Leafy Vegetables around Nairobi
Provedor de dados: 31
Autores: Irungu,   C.; Mburu,   John G.; Maundu,   P.; Grum,   Mikkel; Hoeschle-Zeledon,   I.
Production and marketing of African Leafy Vegetables (ALVs) has increasingly become important in areas surrounding Nairobi. This is mainly due to Nairobians' realization of their nutritional value. ALVs are particularly rich in mineral nutrients and vitamins that are useful in the management of ailments including HIV/AIDS. In addition, these vegetables remain extremely important for overcoming food insecurity and alleviating poverty among the rural and urban populations as they are relatively affordable. Alongside these private uses, ALVs also have a public value which includes maintenance of traditions and culture, and contribution to sustainable development, specifically in the conservation of biodiversity alongside other ecosystem benefits. Despite this...

Opportunity Costs of Providing Crop Diversity in Organic and Conventional Farming: Would Targeted Environmental Policies Make Economic Sense?
Provedor de dados: 31
Autores: Sipilainen,   Timo; Huhtala,   Anni.
Targeted environmental policies for farmlands may improve the cost-efficiency of conservation programs if one can identify the farms that produce public goods, or environmental outputs, with the least cost. We derive shadow values of producing crop diversity on conventional and organic crop farms to examine their opportunity costs of conservation. Non-parametric distance functions are estimated by applying data envelopment analysis to a sample of Finnish crop farms for the period 1994 – 2002. Our results show that there is variation in the shadow values between farms and the technologies adopted. The extent of cost heterogeneity and farms’ potential for specialization in the production of environmental outputs determine whether voluntary programs such as...

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...

Linking biodiversity, land-use and incomes at the farm level: an interdisciplinary modelling approach
Provedor de dados: 31
Autores: Acs,   Szvetlana; Dallimer,   Martin; Hanley,   Nick; Gaston,   Kevin J.; Armsworth,   Paul R.
Recent decades have witnessed substantial losses in biodiversity in Europe, partly driven by the ecological changes associated with intensification of agricultural production. These changes have particularly affected biodiversity in marginal areas, such as the uplands in UK, since habitat change has been greater than in lowland zones. Livestock farming is the main land use in these areas, and economic viability of farmers substantially relies on income coming from agricultural subsidies and agrienvironmental payments. The production decisions have an effect on biodiversity, although the precise links are subject of much debate. To assess the effects of policy changes on farm incomes and biodiversity, we developed ecological-economic models for three...

Agri-Environmental Policies When the Spatial Pattern of Biodiversity Reserves Matters
Provedor de dados: 31
Autores: Bamiére,   Laure; David,   Maia; Vermont,   Bruno.
The aim of this paper is to compare different policy instruments for cost-effective habitat conservation on agricultural lands, when the desired spatial pattern of reserves is a random mosaic. We use a spatially explicit mathematical programming model which studies the farmers' behavior as profit maximizers under technical and administrative constraints. Facing different policy measures, each farmer chooses its land-use at the field level, which determines the landscape at the regional level. A spatial pattern index (Ripley L function) is then associated to the obtained landscape, indicating on the degree of dispersion of the reserve. We compare a subsidy per hectare of reserve with an auction scheme and an agglomeration malus. We find that the auction is...

A Bioeconomic Analysis of the Duration of Conservation Contracts
Provedor de dados: 31
Autores: Crowe,   Bronwyn; White,   Benedict.
Conservation and restoration of native vegetation is often a gradual process which may require many years to transform an ecosystem from one vegetative state to a target ecosystem. This process is stochastic, with some changes potentially irreversible. In contrast, contracts with landholders to undertake conservation measures on their property are typically for less than ten years and often make no contingencies for re-contracting at the end of the contract period. The risk to land holders and conservation agencies of contracts not being renewed and the consequent potential loss of previous investment means including covenants in conservation contracts may be attractive to both parties. A model is developed to empirically examine the optimal dynamic...

Sustainability: The Economic Bottom Line
Provedor de dados: 31
Autores: Tisdell,   Clement A.
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...

Do Farmers Internalise External Impacts of Pesticides in Production?
Provedor de dados: 31
Autores: Skevas,   Theodoros; Stefanou,   Spiro E.; Oude Lansink,   Alfons G.J.M.
In modern agriculture, pesticides feature so prominently in growers’ arsenal to reduce crop damage caused by various pests and diseases. But their indiscriminate use can harm human health and the environment and, eventually, impact agricultural productivity negatively. In an era of an increasing public awareness on the external effects of pesticides, the EU is trying to update its pesticide policy by establishing tax and levy schemes. An important question is whether the external impacts of pesticides are also affecting the farmers’ production environment. A damage abatement specification is used consisting of a potential output function and a damage abatement function. The damage abatement function considers both high and low toxicity pesticides, and...

Modelling Synergies and Scope Economies between Farm Enterprises and Ecosystem Outputs in the Agricultural Sector in England and Wales
Provedor de dados: 31
Autores: Fleming,   Euan M.; Hadley,   David; Holloway,   Garth J.
Interest has been growing in the nature of synergies in agroecosystems, prompted in part by growing concerns about the effects of environmental degradation on agricultural productivity and interrelations between agricultural outputs and ecosystem outputs. Most productivity analyses focus on technology, technical inefficiency and scale effects on productivity; yet scope economies derived from synergies can also have substantial effects that are likely to increase in the future. Scope economies take on special importance when farms diversify to halt declining biodiversity and other forms of environmental degradation. We present results of an empirical case study based on panel data on farms in England and Wales. A stochastic input distance function is...

RESOURCE EXPLOITATION, BIODIVERSITY LOSS AND ECOLOGICAL EVENTS
Provedor de dados: 31
Autores: Tsur,   Yacov; Zemel,   Amos.
We study the management of a natural resource that supports ecosystems as well as human needs.   The reduction in the resource base introduces a threat of occurrence of catastrophic ecological events, such as the sudden collapse of the national habitat that lead to severe loss of biodiversity.  The event occurrence conditions involve uncertainty of various types, and the distinction among these types affects the optimal exploitation policies.  When uncertainty is due to our ignorance of some aspects of the underlying ecology, the isolated equilibrium states characterizing optimal exploitation for many renewable resource problems become equilibrium intervals.  Events triggered by genuinely stochastic environmental conditions maintain the structure of...

Biosecurity incursion response decisions require timely, high quality information involving science and economics. The value of the impact on indigenous biodiversity is a key aspect of the economics typically involving cost-benefit analysis. The hypothetical incursion of Biosecurity New Zealand’s top priority weed hydrilla (Hydrilla verticillata) in a typical New Zealand lake (Lake Rotoroa otherwise known as Hamilton Lake) elicits dollar values of impacts on indigenous biodiversity in a freshwater environment. Using the stated preference tool, Choice Modelling, the experimental design was maximised for efficiency of Willingness to Pay (WTP) estimation.

Definitions of Biodiversity and Measures of Its Value
Provedor de dados: 31
Autores: Simpson,   R. David.
The destruction of natural habitats has prompted concerns about the loss of biological diversity. Regrettably, however, there is no consensus among either biologists or economists on the most meaningful measures of biodiversity. Fundamentally different definitions are useful in asking fundamentally different questions. Considerable attention has been given to the value of diversity in search models. A measure of "aggregate variability" is appropriate to such models. Values derived from search models tend to be well behaved; they exhibit diminishing returns in diversity. In contrast, a definition of diversity as "relative abundance" is more appropriate to more complex objective functions. Values derived in these models are not necessarily well behaved. The...

Linking Policies for Biodiversity Conservation with Advances in Behavioral Economics
Provedor de dados: 31
Autores: Tisdell,   Clement A.
Global biodiversity loss and its consequences for human welfare and sustainable development have become major concerns.  Economists have, therefore, given increasing attention to the policy issues involved in the management of genetic resources.  To do so, they often apply empirical methods developed in behavioral and experimental economics to estimate economic values placed on genetic resources.  This trend away from almost exclusive dependence on axiomatic methods is welcomed.  However, major valuation methods used in behavioral economics raise new scientific challenges. Possibly the most important of these include deficiencies in the knowledge of the public (and researchers) about genetic resources, implications for the formation of values of supplying...

Farmer management of production risk on degraded lands: the role of wheat genetic diversity in Tigray Region, Ethiopia
Provedor de dados: 31
Autores: Di Falco,   Salvatore; Chavas,   Jean-Paul; Smale,   Melinda.
This paper investigates the effects of wheat genetic diversity and land degradation on risk and agricultural productivity in less favored production environments of a developing agricultural economy. Drawing production data from household survey conducted in the highlands of Ethiopia, we estimate a stochastic production function to evaluate the effects of variety richness, land degradation, and their interaction on the mean and the variance of wheat yield. Ethiopia is a centre of diversity for durum wheat and farmers manage complex variety mixtures on multiple plots. Econometric evidence shows that variety richness increases farm productivity. Variety richness also reduces yield variability but only for high levels of genetic diversity. Simulations with...

An Investigation into the Net Benefits of Revegetating Agricultural Land with Indigenous Species in the Dryland Section of the Goulburn-Broken Catchment Area
Provedor de dados: 31
Autores: Trapnell,   Lindsay N.
Benefits ascribed to the revegetation of farming landscapes include enhancement of biodiversity, reduction in the advance of dryland salinity, sequestration of greenhouse gases, control of soil erosion, greater protection of agricultural activities from adverse weather conditions and an improved aesthetic value of rural lands. In this paper, economic analyses were performed to determine the net benefits to landholders of carrying out revegetation. Where the net benefits were insufficient to allow reasonable returns to be earned on the investment of marginal capital, an assessment was made of the amount and type of assistance that would be necessary to encourage landholders to adopt this improved system of land management.

Recent decades have witnessed substantial losses in biodiversity in Europe, principally driven by the ecological changes associated with intensification of agricultural production. These changes especially affected the biodiversity in the marginal areas, such as the uplands in UK, since the habitat change was greater than in lowland zones. Livestock farming is the main land use in these areas, and economic viability of these farmers substantially relies on income coming from agricultural subsidies and different agri-environmental payments. The production decisions are influenced by these incentives and those have a subsequent effect on biodiversity. In order to address the problem of economic viability of farmers together with its impact on biodiversity...

Multifunctionality: Environment versus Rural Viability in Social Optima
Provedor de dados: 31
Autores: Ollikainen,   Markku; Lankoski,   Jussi E.
We examine policy implications of including rural viability to the notion of multifunctional agriculture. We assume that rural viability refers predominantly to the number of people living in rural areas to keep the infrastructure and living conditions at good state for a good life. The economic core of viability is employment in agriculture and agriculture serving sectors. Viability benefits are modelled with the help of a viability valuation function. We demonstrate that rural viability entails adjusting fertilizer tax and buffer strip subsidy below their environmental first-best Pigouvian levels to reflect the direct and indirect employment effects of agricultural production. Moreover, when non-agricultural land use is present, an additional,...

The spatial pattern of landscape reconstruction makes a substantial difference to environmental outcomes. We develop a spatially explicit bio-economic model that optimises the reconstruction of a heavily cleared landscape through revegetation. The model determines the spatial priorities for revegetation that minimises economic costs subject to achieving particular improvements in habitat for 29 woodland-dependent bird species. The study focuses on the Avoca catchment (330 thousand ha) in North-Central Victoria. Our model incorporates spatial pattern and heterogeneity of existing and reconstructed vegetation types. The revegetation priorities are identified as being: sites in the vicinity of existing remnants, riparian areas, and parts of the landscape with...

An experiment involving 204 residents of Brisbane, Australia is outlined and the results are reported and analysed. Two consecutive surveys of the respondents provide data about their stated knowledge of 23 wildlife species present in tropical Australia, many of which exclusively occur there. In addition, these surveys provide data about the willingness of respondents to pay for the conservation of those species belonging to three taxa: reptiles, mammals, and birds. The respondents’ stated knowledge of the species is compared with their willingness to pay for species’ conservation, and relevant inferences are drawn. When the respondents’ knowledge of the species is experimentally increased in a balanced way, it is found to result in more dispersion...

Valuation of Biodiversity for Use in New Product Research in a Model of Sequential Search
Provedor de dados: 31
Autores: Simpson,   R. David; Sedjo,   Roger A.
We develop a model of search in which a researcher chooses the size of sequential batches of samples to test. While earlier work has considered similar questions, the contribution of this paper is to use the search model to place a value on the marginal research opportunity. The valuation of such opportunities may be of little interest or relevance in many of the contexts in which search models are employed, but we apply our analysis to an area of considerable societal interest: the valuation of biological diversity for use in new product research. While data from which to make inferences are limited, we find that, using plausible estimates of relevant parameters, the value of biodiversity in these applications is negligible.

An analytical framework is proposed for analysis of environmental good production by farmers in the case of price uncertainty.  Environmental good production contracted by means of agri-environmental agreements is treated as a risk less option in the farmer's production activities portfolio.  Efficient frontiers were generated using mathematical programming farm level models of suckler cow farms in Monts du Cantal, in France.  It was demonstrated that for a DARA risk averse farmer: 1) the agreement payment level is not without impact on the farming intensity on parcels not subscribed under the corresponding argi-environmental programme, 2) a lump sum payment matters under uncertainty, 3) the overall impact of the lump sum payment on environmental good...

The paper investigates the value of biodiversity as it relates to the productive value of services provided by an ecosystem. It analyzes how the value of an ecosystem can be "greater than the sum of its parts." First, it proposes a general measure of the value of biodiversity. Second, this measure is decomposed into four components, reflecting the role of complementarity, scale, convexity, and catalytic effects. This provides new information on the sources and determinants of biodiversity value. Third, the paper examines the role of uncertainty. In this context, the role of risk and of downside-risk exposure and their effects on the value of biodiversity are explored. This provides useful insights on how management and policy decisions can affect the value...

ABSTRACT Intensive land use can affect macrofaunal biodiversity, which is a property that can be used as a soil quality indicator. This study evaluated the abundance and diversity of soil macrofauna and its relation to soil chemical and physical properties in five land use systems (LUS) in the eastern region of Santa Catarina. The following LUS were studied: native forest (NF), eucalyptus plantations (EP), perennial pasture (PP), integrated crop-livestock (ICL), and no-tillage cropping (NT). The macrofauna was quantified in 0.25 × 0.25 m monoliths and sampled in the 0.00-0.20 m layer in the summer (Jan/2012) and winter (Jul/2012). For each LUS, nine points were sampled, distributed in a 30 × 30 m sampling grid. After screening the edaphic macrofauna...

Autores: Nogueira,Leandro Ribeiro; Silva,Cristiane Figueira da; Pereira,Marcos Gervasio; Gaia-Gomes,João Henrique; Silva,Eliane Maria Ribeiro da.
ABSTRACT The removal of original vegetation for crops and pasture production and then followed by natural regeneration is a standard practice in the Atlantic Forest, which has produced patches with different degrees of degradation and regeneration across the landscape. The aim of this study was to evaluate the effects of replacement of native forest by pasture and natural regeneration of vegetation on soil and on soil organic matter (SOM) dynamics in the dry and rainy season in an Atlantic Forest fragment in Passa Vinte, Minas Gerais (MG), Brazil. Soil samples were collected in the rainy and dry season, at a depth of 0.00-0.05 m. The variables determined were total organic carbon (TOC) and particle-size fractions of SOM [particulate organic carbon (POC)...

Provedor de dados: 92
Autores: Souza,Heitor Bruno de Araújo; Alves,Wagner de França; Vasconcellos,Alexandre.
Termites are abundant organisms in tropical ecosystems and strongly influence the litter decomposition and soil formation. Despite their importance, few studies about their assemblage structures have been made in Brazilian Atlantic Forest fragments, especially in the area located north of the São Francisco River. This study aims to analyze the assemblage composition of five Atlantic Forest fragments located in the northern biome limit along the Brazilian coast. A standardized sampling protocol of termites was applied in each fragment. Thirty-three termite species belonging to twenty genera and three families were found in the forest fragments. The wood-feeder group was dominant both concerning to species richness and number of encounters in all areas. In...

Autores: Harada,L. M.; Araújo,I. S.; Overal,W. L.; Silva,F. A. B.
Abstract In order to evaluate the impact of oil palm cultivation on dung beetles in the eastern Brazilian Amazon, comparisons were made of communities in oil palm plantations and native forest. Pitfall traps baited with human feces were buried to soil level in plantations and surrounding forests. Fifty traps were used in each type of vegetation, placed at 50 m intervals along five transects. Dung beetle communities in oil palm plantations have lower species richness (18 spp.) than in surrounding tropical rainforest (48 spp.), as well as altered species composition. Total abundance of individuals was not significantly different between the two habitats, but species composition was greatly different. Species evenness was greater in the forest. Forest...

Autores: Gomes,Diego S.; Elizalde,Luciana; Queiroz,Jarbas M.
Parasitoids of the endangered leafcutter ant Atta robusta Borgmeier in urban and natural areas. Hosts of parasitoids in urban areas may suffer from a double threat of habitat destruction by urbanization and parasitism pressure. Moreover, the parasitoids themselves might be at risk if they are specialists. Here, we studied whether Atta robusta (Hymenoptera, Formicidae), which is on the red list of Brazilian threatened species, suffers from higher parasitism pressure in an urban area compared to a natural one. In addition, we determined whether their specialist parasitoids, Eibesfeldtphora breviloba and Myrmosicarius exrobusta (Diptera, Phoridae), are in risk and evaluated whether they are influenced by habitat structure, temperature, humidity, ant traffic,...

Autores: Silveira,Orlando Tobias; Silva,Suzanna de Sousa; Pereira,Jorge Luis Gavina; Tavares,Ingrid da Silva.
Polistine wasps are important in Neotropical ecosystems due to their ubiquity and diversity. Inventories have not adequately considered spatial attributes of collected specimens. Spatial data on biodiversity are important for study and mitigation of anthropogenic impacts over natural ecosystems and for protecting species. We described and analyzed local-scale spatial patterns of collecting records of wasp species, as well as spatial variation of diversity descriptors in a 2500-hectare area of an Amazon forest in Brazil. Rare species comprised the largest fraction of the fauna. Close range spatial effects were detected for most of the more common species, with clustering of presence-data at short distances. Larger spatial lag effects could also be...

ABSTRACTThis study reviewed the data on the Brazilian Ephemeroptera, based on the studies published before July, 2013, estimated the number of species still to be described, and identified which regions of the country have been the subject of least research. More than half the species are known from the description of only one developmental stage, with imagoes being described more frequently than nymphs. The Brazilian Northeast is the region with the weakest database. Body size affected description rates, with a strong tendency for the larger species to be described first. The estimated number of unknown Brazilian species was accentuated by the fact that so few species have been described so far. The steep slope of the asymptote and the considerable...

Despite the speciose fauna of gall-inducing insects in the Neotropical region, little is known about their taxonomy. On the other hand, gall morphotypes associated with host species have been extensively used as a surrogate of the inducer species worldwide. This study reviewed the described gall midges and their galls to test the generalization on the use of gall morphotypes as surrogates of gall midge species in the Brazilian fauna. We compiled taxonomic and biological data for 196 gall midge species recorded on 128 host plant species. Ninety two percent of those species were monophagous, inducing galls on a single host plant species, whereas only 5.6% species were oligophagous, inducing galls on more than one congeneric host plant species.

ABSTRACT Moncini is the tribe of Hesperiidae that comprises the greatest diversity of small, brown, hard to identify skippers. The group is peculiarly classified as having many monotypic genera, thus offering low informative value to its systematics. This study presents a review of the genus Gallio Evans, 1955, a genus formerly recognized as monotypic, and describes three new species, Gallio imperatriz sp. nov. from Maranhão, Brazil, Gallio furtadoi sp. nov. from Mato Grosso, Brazil and Gallio eti sp. nov. from Madre de Díos, Peru and Acre, Brazil (type locality). A lectotype for Vehilius carasta Schaus, 1902 is designated. Gallio is therefore redescribed and illustrations and diagnosis to its species are provided.

ABSTRACT Filling gaps in species distributions is instrumental to increase our understanding of natural environments and underpin efficient conservation policies. For many hyperdiverse groups, this knowledge is hampered by insufficient taxonomic information. Herein we provide 415 new distribution records for the parasitic wasp subfamily Cryptinae (Hymenoptera, Ichneumonidae) in the Neotropical region, based on examination of material from 20 biological collections worldwide. Records span across 227 sites in 24 countries and territories, and represent 175 species from 53 genera. Of these, 102 represent new country records for 74 species. A distinct "road pattern" was detected in the records, at least within Brazil, where 50.2% of the records fall within 10...

ABSTRACT The invasive white ginger lily (Hedichium coronarium - J. Köenig, 1783) simplifies the trait composition of an insect assemblage in the littoral zone of a Savanna reservoir. Invasive plants are believed to shift the trait composition of aquatic insects dwelling in banks of lentic ecosystems. In this study, we analyzed the relationship between the presence of the invasive white ginger lily (H. coronarium) and the functional trait indices of the aquatic insect assemblage in the littoral zone of a tropical reservoir. We sampled aquatic insects on the invaded and non-invaded banks of the reservoir and then analyzed the insect trait indices by estimating the Functional Dispersion (FDis), Functional Evenness (FEve) and the Functional Divergence (FDiv),...

Ephemeroptera exhibits great diversity among bodies of freshwater in the Atlantic Forest, a biome that is suffering from massive human impact. Within this context, the creation of conservation units using biological information is more recommended than economic, cultural, or political criteria. The distribution pattern of 76 Ephemeroptera species was analyzed using the biogeographical methods Parsimony Analysis of Endemicity and Network Analysis Method in order to infer relevant areas for conservation of the mayfly community in Espírito Santo. The results obtained from both analyses were largely congruent, and pointed out four relevant areas for conservation: two in...

Autores: Souza,Rosa C. C. L. de; Trindade,Denise C.; Decco,Juber de; Lima,Tania A.; Silva,Edson P.
A reference inventory of prehistoric marine mollusks from the Rio das Ostras region was created based on an excavation carried out at the Sambaqui da Tarioba shellmound. Patterns of richness and biogeography were studied, and the representativeness of bivalve and gastropod diversities found at this archaeological site were inferred. A total of 47 taxa belonging to 28 families, most of which from unconsolidated substrates, was identified. The shellmound species composition does not differ from the present-day composition. All recorded species are characteristic of a wide transition zone between the south of the states of Espírito Santo (21°S) and Rio Grande do Sul (32°S). Thus, the data show little evidence of evolution in the composition, richness,and...

Revolutionary thoughts on taxonomy: declarations of independence and interdependence
Provedor de dados: 103
Autores: Wheeler,Quentin D.
Credible biological research depends on accurate species identifications, reliable scientific names, and an evolutionary context provided by a phylogeny or phylogenetic classification. The emphasis on such taxonomic services has detracted from the fundamental taxonomic research necessary to create and sustain such knowledge systems. A taxonomic declaration of independence is presented, emphasizing the unique mission, goals, and needs of taxonomists and taxonomic (collection-based) institutions and the non-experimental yet scientifically rigorous epistemology of taxonomy. At the same time taxonomic interdependence is declared. Questions pursued by taxonomists are planetary in scale and can only be answered given international collaboration and coordination...

Does urbanization have positive or negative effects on Crab spider (Araneae: Thomisidae) diversity?
Provedor de dados: 103
Autores: Argañaraz,Carina I.; Gleiser,Raquel M.
ABSTRACT Urbanization has a great impact on the diversity of living organisms. Spiders, for example, have been shown to respond negatively (some orb weaving species) and positively (ground dwelling species) to urbanization. The effects of urbanization on crab spiders (Thomisidae) (sit-and-wait predators that generally ambush their prey on flowers and leaves) are not sufficiently known. This paper describes the Thomisidae community that inhabits green patches in a temperate Neotropical city, Cordoba, Argentina, and its surroundings, and ascertains whether there are differences in species richness, abundance and composition between urban and exurban sites. Samples were collected from 30 sites during the summer and spring of 2013 and 2014, using the...

Species richness and community composition of sphingid moths (Lepidoptera: Sphingidae) along an elevational gradient in southeast Peru
Provedor de dados: 103
Autores: Sublett,Clayton A.; Cook,Jerry L.; Janovec,John P.
ABSTRACT A clear low-elevation skewed unimodal richness pattern is presented for hawkmoths in Southeast Peru. Several hypotheses offer plausible explanations for such a distribution. The effects of water-energy dynamics are partially supported by a strong correlation between temperature and species richness at higher elevations. Further, hypotheses of plant diversity influences on hawkmoth ranges are supported by species richness peaking in transitional habitats. Sphingid subfamilies do not appear to be influenced by habitat type or elevational factors, such as temperature. This may make subfamily analysis a poor means of characterizing sphingid community composition unless study sites vary in the level of disturbance. This study documents 134 species in...

ABSTRACT Studies that address biodiversity and its supporting mechanisms in different ecosystems are fundamental to understanding the relationships between species and the prevailing environmental conditions within each habitat type. This study presents information on the phenology of Promestosoma boggianii (Silvestri, 1898) and its association with seasonal flood and dry events in a floodplain of Mato Grosso’s northern Pantanal region, Brazil. Sampling was carried out in three areas located between the Bento Gomes and Cuiabá rivers, on the Porto Cercado Road, Poconé-MT. Each sample area was composed of two treatments: (I) floodable habitats and (NI) non-floodable habitats. Three quadrats (10 x 10 m) were established within each treatment, with sampling...

Autores: Couto,Alane A.V.O.; Albuquerque,Auristela C.; Vasconcellos,Alexandre; Castro,Cibele C.
ABSTRACT We compared the termite assemblages of different ecosystems in a humidity gradient. Three areas were sampled: (i) a humid montane forest; (ii) a hillside forest where shaded coffee (Coffea arabica Linnaeus, 1753) is cultivated; (iii) a seasonally dry forest (Caatinga). Active collection protocols were employed in each area during the dry and rainy seasons. The species were grouped according to their habitats and feeding habits. A total of 45 termite species belonging to 20 genera and three families were encountered. The termite fauna of the Caatinga was as rich and abundant as that of the humid forest areas, but it was distinct from it in species composition. Most termite species encountered in the montane forest were also found in the...

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...

Provedor de dados: 96
Autores: Antunes,Karine Vieira; Machado,Théa Mírian Medeiros; Serão,Nicola Vergara Lopes; Guimarães,Simone Eliza Facione; Paiva,Samuel Rezende.
The genetic diversity was analyzed among spotted paca (Agouti paca) from three commercial flocks located in Brazil. As the genome of this species is unknown, the RAPD-PCR technique was used. Ten primers generated sixty polymorphic bands. The among and within population genetic variability estimated by analysis of molecular variance (AMOVA) was 12.55 and 87.45%, respectively. The shortest Nei distance value was 11.76% among the Carangola (CG) and São Francisco do Glória (SF) populations. This value can be explained by the exchange of reproduction males and females between the two geographically close breeding sites. The analysis of principal components showed well defined and structured groups aggregating animals according their population of origin, with...

Characterization of biological types of cattle: indicator traits offertility in beef cows
Provedor de dados: 96
Autores: Cushman,R.A.; Allan,M.F.; Kuehn,L.A.
Genetic diversity among breeds of cattle allows producers to select animals for specific environments or market conditions. Reproductive efficiency is a multi-component trait that is largely influenced by environmental influences such as health and nutritional status; however, there are clearly genetic components to reproductive efficiency, and breed differences in a number of indicator traits associated with fertility and cow productivity have been identified. Historical indicators of fertility include scrotal circumference, age at puberty, and postpartum interval. Both age at puberty and postpartum interval are laborious traits to collect in heifers and cows because they require many days of detection of behavioral estrus. In recent years, the addition...

ABSTRACT In this study, we investigated the differentiation of five different chicken ecotypes - Center, North, South, West, and East - of Saudi Arabia using discriminate analysis. The analysis was based on nine important morphological and phenotypic traits: body color, beak color, earlobe color, eye color, shank color, comb color, comb type, comb size, and feather distribution. There was a strong significant relationship between the phenotype and effect of geographic height in terms of comb type and earlobe color in males as well as body, beak, eye, and shank color. In particular, the comb type and earlobe color differentiated the ecotypes of males. Among the females, the beak, earlobe, eye, shank color, and feather distribution had more differentiating...

Breeds in danger of extintion and biodiversity
Provedor de dados: 96
Autores: Blasco,A.
Some arguments currently used to support breed conservation are examined. The central point is that we cannot conserve all breeds because we do not have financial resources enough to keep everything (mainly in developing countries) and in many cases we do not have special reasons to conserve breeds. A breed is a human product and it should not be confused with specie. A breed can be generated or transformed. We can create synthetic breeds with the best characteristics of several breeds. Selection is not exhausting genetic variability (there are several experiments showing that), and genetic variability within breeds is large. We need reasons to keep breeds in danger in extinction. A breed is a tool, and we can decide to keep it when it is useful because it...

Metallophytes in Latin America: a remarkable biological and genetic resource scarcely known and studied in the region
Provedor de dados: 97
Autores: GINOCCHIO,ROSANNA; BAKER,ALAN J.M.
In Latin America, metallic ores are abundant and diverse. However, few metal-tolerant and metal hyperaccumulator plants have been reported in the region in comparison with other areas of the world. This may be largely explained by the scarcity of scientific studies of the native vegetation growing on natural mineralized or metal-contaminated areas and the unfrequent use of biogeochemical prospecting techniques by the local mining industry, rather than the proven absence of these plants. Latin America is, however, an area where metal-tolerant and hyperaccumulator plants (metallophytes) should be found, not only because of the wealth of ore deposits and associated metal polluted areas, but also due to its high and unique plant diversity. If plant formations...

Changes in tree species richness, stand structure and soil properties in a successional chronosequence in northern Chiloé Island, Chile
Provedor de dados: 97
Autores: ARAVENA,JUAN C.; CARMONA,MARTÍN R.; PÉREZ,CECILIA A.; ARMESTO,JUAN J.
We studied a chronosequence of forest fragments in northern Chiloé Island, southern Chile, with the aim of assessing ecosystem recovery patterns following anthropogenic disturbance. Hypotheses regarding successional trends in tree species richness, the replacement of shade-intolerant by shade-tolerant species, and the impact of disturbance on soil properties were evaluated in nine forest stands. The chronosequence encompassed two early (minimum stand age &lt;15 years), three mid-successional (30-60 years), three late-successional (129-134 years), and one old-growth stand (ca. 200 years). Stand ages were estimated by coring a minimum of 30 canopy trees in each stand. Early and mid-successional stands showed evidence of human disturbance by fire of moderate...

Marine photosynthetic eukaryotes in polar systems: Unveiling phytoplankton diversity and composition in Antarctic waters
Provedor de dados: 97
Autores: DE LA IGLESIA,RODRIGO; TREFAULT,NICOLE.
Antarctic waters are a particular marine environment mainly due to the strong seasonal variations that various parameters are subject to, like light availability and temperature. As in all oceanographic regions, food webs are sustained by photosynthetic microorganisms, which in the case of Antarctic environments seem to be strongly dominated by its eukaryote component. Assessing the ecological role of photosynthetic microbial eukaryotes requires a basic knowledge of their diversity and community composition. This review integrates the available information regarding this component of Antarctic phytoplankton as a way to unveil its diversity and how they respond to the strong changes that occur in this environment. Although several studies indicate the...

Aleuas uruguayensis Carbonell (Orthoptera, Acrididae, Copiocerinae): novel occurrence in the Paranaense biogeographic province
Provedor de dados: 99
Autores: Taffarel,Alberto; Castillo,Elio R. D.; Acuña,Fernando N.; Krauczuk,Ernesto; Marangoni,Federico; Martí,Dardo A.
The Neotropical genus Aleuas Stål 1878 is constituted by nine recognized species, distributed in South America. This genus is closely related to Adimantus Stål 1878, Zygoclistron Rehn 1905 and Episcopotettix Rehn 1903 (Copiocerinae). Only four species of Aleuas have been reported in Argentina, covering different phytogeographical provinces: A. gracilis Stål 1878, A. lineatus Stål 1878, A. paranensis Carbonell 2008 and A. vitticollis Stål 1878. In this contribution we provide novel records for A. uruguayensis and illustrate the geographic distribution of the species. This work extends the known distribution range of the species as well as it contributes to the general knowledge on the Orthoptera diversity in Argentina.

Autores: Jaramillo,Paula Marcela Duque; Guimarães,Amanda Azarias; Florentino,Ligiane Aparecida; Silva,Karina Barroso; Nóbrega,Rafaela Simão Abrahão; Moreira,Fatima Maria de Souza.
Cowpea (Vigna unguiculata) is an important grain-producing legume that can forego nitrogen fertilization by establishing an efficient symbiosis with nitrogen-fixing bacteria. Although inoculating strains have already been selected for this species, little is known about the genotypic and symbiotic diversity of native rhizobia. Recently, Bradyrhizobium has been shown to be the genus most frequently trapped by cowpea in agricultural soils of the Amazon region. We investigated the genetic and symbiotic diversity of 148 bacterial strains with different phenotypic and cultural properties isolated from the nodules of the trap species cowpea, which was inoculated with samples from soils under agroforestry systems from the western Amazon. Sixty non-nodulating...

Autores: Baretta,Dilmar; Brown,George Gardner; James,Samuel Wooster; Cardoso,Elke Jurandy Bran Nogueira.
Araucaria angustifolia, also known as the Paraná Pine is an endangered tree species in Brazil and little is known of the diversity of soil invertebrates inhabiting these forests. Therefore, the present study was set up to evaluate the biomass and diversity of earthworms in natural and reforested Araucaria plots, impacted or not by fire, and to identify the most efficient earthworm collection method. Four study areas included: native forest with Araucaria (NF); Araucaria reforestation (R); Araucaria reforestation submitted to an accidental fire (RF); and native grass pasture with native Araucaria and submitted to an intense accidental fire (NPF). Five soil samples containing the earthworm community were taken in a 0.3 ha area in each of the forest sites,...

Spore density and root colonization by arbuscular mycorrhizal fungi in preserved or disturbed Araucaria angustifolia (Bert.) O. Ktze. ecosystems
Provedor de dados: 63
Autores: Moreira,Milene; Baretta,Dilmar; Tsai,Siu Mui; Cardoso,Elke Jurandy Bran Nogueira.
Araucaria angustifolia (Bert.) O. Ktze., a native forest tree from Brazil, is under extinction risk. This tree depends on arbuscular mycorrhizal fungi for growth and development, especially in tropical low-P soils but, despite being a conifer, Araucaria does not form ectomycorrhiza, but only the arbuscular endomycorrhiza. This study aimed at surveying data on the spore density and root colonization (CR) by arbuscular mycorrhizal fungi (AMF) in Araucaria angustifolia forest ecosystems, in order to discriminate natural, implemented, and anthropic action-impacted ecosystems, by means of Canonical Discriminant Analysis (CDA). Three ecosystems representative of the Campos do Jordão (SP, Brazil) region were selected: 1. a native forest (FN); 2. a replanted...

The knowledge of insect biodiversity in natural areas of Argentina is limited, and termites are among the understudied taxa. In order to assess the diversity of Isoptera in some protected areas of the country, termite sampling within three National Parks of the Northeast region of Argentina was developed during 1995-1999. The results presented in this paper correspond to the Chaco National Park (Province of Chaco), Iguassu National Park (Province of Misiones) and Mburucuya National Park (Province of Corrientes). Among the four termite families recorded from Argentina, the family Termitidae was the best represented at the three sampled areas. The recorded genera (15) were: Rugitermes Holmgren and Tauritermes Krishna (Kalotermitidae), Heterotermes Frogatt...

Noteworthy bird records at Lagoa Santa, southeastern Brazil
Provedor de dados: 104
Autores: Rodrigues,Marcos.
Lagoa Santa, a small town in southeastern Brazil where naturalist Peter Lund lived, is regarded nowadays as an important historical site for the biological sciences. From 1847 to 1855, J.T.

Padrões de abundância, riqueza e diversidade de moluscos bivalves na plataforma continental ao largo de Ubatuba, São Paulo, Brasil: uma comparação metodológica
Provedor de dados: 104
Autores: Soares-Gomes,Abílio; Pires-Vanin,Ana Maria Setubal.
The diversity and richness patterns of bivalve molluscs were studied on the continental shelf of Ubatuba (23º38'S, 45º14'W and 23º25'S, 44º51'W) between 15-120 metres depth. The samples were taken with a rectangular dredge and a beam trawl. The results showed higher values of richness, diversity and evenness for inner shelf (from coast to nearly 50 m depth) and greater values of abundance for outer shelf (from 50 to around 120 m depth). This pattern might be due to the higher instability of the inner shelf, which is influenced by the seasonal intrusion of the South Atlantic Central Water (SACW) and the occurrence of cold fronts. Sanders' rarefation curves, distribution and abundance curves and DIMO model were used and the results compared. The Qinghong's...

Autores: Feres,Reinaldo J.F.; Rossa-Feres,Denise de C.; Daud,Rodrigo D.; Santos,Rodrigo S.
The mites of three rubber tree cultures (Cedral, Pindorama and Taquaritinga) in order to determine the abundance of populations, the richness, the diversity and the degree of similarity among the communities was studied. Twenty one species were found, five of which were common to the three cultures. The richness and the abundance were greatest at the beginning of the dry season. The composition of communities differed probably as consequence of the kind of neighboring vegetation to each area, and because of the acaricid pulverization on the culture of Taquaritinga, reductng the richness of mite species in that area. The influence of neighboring vegetation can be shown by the occurrence of Iphiseiodes zuluagui Denmark &amp;amp; Muma, 1972, a common species...

The understanding of the distribution and richness patterns of species is very important in ecology. Also, for the Cerrado region, this is very important and urgent, because of the strong pressure for new areas designated for agriculture. In five areas of the Cerrado, an exploratory study was carried out on the diversity, evenness and similarity of moth species. Moths were captured in a white sheet hung vertically and illuminated by a 250 Watt mercury vapor lamp. The alpha diversity was calculated using the Shannon-Wiener index (H') and the Simpson index (γ). The beta diversity was examined for all sampled localities and estimated by Wittaker's measure. The Sörensen and Jaccard indexes were used to calculate similarity. A total of 11130 individuals, 1064...

Autores: Vasconcelos,Heraldo L.; Araújo,Bruna B.; Mayhé-Nunes,Antonio J.
Fungus-growing ants (tribe Attini) are characteristic elements of the New World fauna. However, there is little information on the patterns of diversity, abundance, and distribution of attine species in their native ecosystems, especially for the so-called "lower" genera of the tribe. A survey of attine ant nests (excluding Atta Fabricus, 1804 and Acromyrmex Mayr, 1865) was conducted in a variety of savanna and forest habitats of the Cerrado biome near Uberlândia, Brazil. In total, 314 nests from 21 species of nine genera were found. Trachymyrmex Forel, 1893 was the most diverse genus with 10 species. Eighteen species were found in the savannas, including Mycetagroicus cerradensis Brandão &amp;amp; Mayhé-Nunes, 2001, a species from a recently-described...

Studies on the communities of galling insects and their host plants were performed in three "cerrado" physiognomies that occur in Minas Gerais: "campo sujo", "cerrado" sensu strictu, and "cerradão". Galls and host plants were collected along transects in a total of 3,000 herbs, 300 shrubs and 135 trees in each physiognomy. Ninety two species of galling insects (morphotypes) on 62 host plant species of 28 families were found. The highest galling insect richness was observed in the "cerrado". Approximately 75.0% of galling insects belonged to the Cecidomyiidae (Diptera). The highest gall frequency was found on leaves (58.70%) of the host plants, and was glabrous (83.70%). Most gall shape were elliptic (30.43%). A low similarity in galling insect species was...

This study reports the mite fauna associated with Tabebuia roseo-alba, a native and ornamental tree, determining the abundance and seasonal occurrence of species and the diversity of the community. Twenty three species were found belonging to 11 families, 10 of predatory habits and five phytophagous. The food habits of the eight remaining species are not known. Besides the great richness, the diversity was small, as consequence of the dominance of Lorryia formosa Cooreman, 1958 and Aculus sp., the most abundant species. These species occurred in the same microhabitat but with seasonal segregation: L. formosa was the most abundant in the dry season, while Aculus sp. occurred only in the rainy season. In August, when the plant lost its leaves, the following...

Autores: RAMOS-PASTRANA,Yardany; CÓRDOBA-SUAREZ,Eric; WOLFF,Marta.
ABSTRACT Blepharicnema splendens is a dipteran with occurrence restricted to the Neotropical Andean mountain forests from 1,400 to 2,500 masl. We surveyed the species using Van Someren-Rydon traps with decaying fish as bait in four sites (veredas) in the Eastern Cordillera, in the Municipality of Florencia, Caquetá, Colombia. A total of 221 individuals were collected in the four localities. The Vereda Las Brisas had the highest abundance, with 104 specimens (45.4%), followed by El Vergel, 76 (33.2%), Tarqui, 46 (20.1%) and Los Lirios, 2 (0.9%). The record of this species in the mountainous ecosystems of the Department of Caquetá expands the known distribution of B. splendens and adds to the incipient knowledge on the diversity of Diptera in this region.

ABSTRACT Termites of the Nasutitermes genus are considered one of the main urban and agroforestry pests in Brazil, where the main method of control is the application of pesticides. The uso of entomopathogenic fungi to reduce the population of this plague in the environment could be use as an alternative. The goal of this study was to evaluate the virulence of isolates native Amazonian fungi belonging to the Tolypocladium endophyticum, Metarhizium anisopliae and Metarhizium marquandii species for the control of Nasutitermes sp. The strains of T. endophyticum (4.439), M. anisopliae (4.443) and M. marquandii (4.472) with their respective isolation codes, were evaluated using suspensions at concentrations of 105, 106, 107 and 108 conidia/mL against the...

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 Several scientific reasons support continuing bird collection in Colombia, a megadiverse country with modest science financing. Despite the recognized value of biological collections for the rigorous study of biodiversity, there is scarce information on the monetary costs of specimens. We present results for three expeditions conducted in Santander (municipalities of Cimitarra, El Carmen de Chucurí, and Santa Barbara), Colombia, during 2018 to collect bird voucher specimens, quantifying the costs of obtaining such material. After a sampling effort of 1290 mist net hours and occasional collection using an airgun, we collected 300 bird voucher specimens, representing 117 species from 30 families. Such collection represents one of the largest series...

SPATIAL RICHNESS PATTERNS OF SOFT-BOTTOM FISH IN THE COLOMBIAN CARIBBEAN CONTINENTAL SHELF AND SLOPE
Provedor de dados: 37
Autores: GARCÍA.,Camilo B.
ABSTRACT This study presents a spatial analysis of species richness of soft-bottom bony and cartilaginous fish species in the Colombian Caribbean. The dataset consisted of 625 species distributed among 15651 georeferenced occurrences. The global richness completeness analysis suggests that the list is close to completion but that probably more species await being registered at greater depths. In spatial terms, our knowledge of fish richness remains incomplete as none of the spatial units, in which the general area was divided reached 100 % completeness and few reached 70 % or higher completeness probably due to the incidence of numerous rare species. The Guajira, Palomino, Tayrona and Golfo de Salamanca zones, displayed the highest observed and predicted...

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: Fonseca,Bárbara Medeiros; Feijó,Lidia Mendes; Mendonça-Galvão,Luciana de.
ABSTRACT This study evaluated soft-bodied benthic algae from seven streams located in protected areas of central Brazil (Parque Nacional de Brasília, Parque Nacional da Chapada dos Veadeiros and Parque Estadual de Terra Ronca), and related them to abiotic factors. We addressed the following questions: A) how algal community structure in Cerrado streams is influenced by the marked seasonality typical of the region; and B) how karst geology influences algal communities in Parque Estadual de Terra Ronca, as compared to streams in other Cerrado areas. Samples were collected between 2012 and 2013 from a single site in each stream, and upstream and downstream of caves present in Parque Estadual de Terra Ronca. Altogether, 159 taxa were recorded. Algal community...

Autores: Quaresma,Adriano C.; Piedade,Maria Teresa F.; Feitosa,Yuri Oliveira; Wittmann,Florian; Steege,Hans ter.
ABSTRACT Research focusing on assemblages of vascular epiphytes in the Amazon are scarce. This is especially true for Amazonian floodplain forests, for which only two previous studies have been published. We compared composition, richness and structure of epiphyte assemblages in white-water and black-water floodplains (várzea and igapó) in Central Amazonia in order to close knowledge gaps concerning the distribution and richness of epiphytes. We established sixteen 25x25 m plots in each forest type, and counted and identified all species of vascular epiphytes occurring on trees with a diameter at breast height (DBH) ≥10 cm. We observed a clear distinction in epiphytic species composition (r2=0.83, p=0.001) and diversity (t=3.24, P=0.003) between the two...

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...

Autores: Gasper,André Luís de; Stehmann,João Renato; Roque,Nádia; Bigio,Narcísio C.; Sartori,Ângela Lúcia Bagnatori; Grittz,Guilherme Salgado.
ABSTRACT Herbaria represent irreplaceable repositories of biodiversity and are used to answer questions about conservation, ecology, systematics, and other sciences. In this sense, we characterize the infrastructure, human resources, and idiosyncrasies of Brazilian herbaria. To achieve this goal, curators were sent a structured and standardized questionnaire to gather information about herbaria. The Brazilian Herbaria Network listed 216 active herbaria in the year 2018, of which 139 answered the questionnaire. These herbaria hold 6,741,469 samples in their collections and more than 39,000 type samples. Most herbaria are in federal universities (40.28 %). Only 24 % of the curators considered that their herbarium is valued by their institutions and 52 %...

ABSTRACT Litter production in forest ecosystems is a major indicator of primary productivity because litter helps incorporate carbon and nutrients from plants into the soil and is directly involved in plant-soil interactions. To our knowledge, few studies have investigated the relationship between species diversity and ecosystem processes in subtropical forest fragments. In this work, we determined forest structural parameters and assessed seasonal leaf litter input, leaf decomposition rate, litter quality and soil characteristics in two subtropical Atlantic Forest fragments. Litter production was greater in the native fragment with the higher species diversity (FN1). The two native fragments (FN1 and FN2) differed in basal area, volume and dominance in...

Weedy and secundary palm species in central amazonian forest Fragments
Provedor de dados: 39
Autores: Scariot,Aldicir.
Forest fragmentation may affect the abundance and distribution of organisms. Some species populations decrease being eventually driven to local extinction while other species may experience population increase. In a survey of the composition and abundance of secondary and weedy palms in eight forest fragments (three of 1-, three of 10- and two of 100-ha), in three sites (Dimona, Porto Alegre and Esteio) in central Amazonia, five native palm species which do not occur in the continuous forest were identified. Three were secondary species (Astrocaryum acaule Mart., Bactris maraja Mart. var. maraja and Bactris sp), one weedy (Lepidocaryum tenue Mart.), and one of unknown status (B. oligocarpa Barb. Rodr. &amp;amp; Trail). The highest abundance was found in...

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....

Galling insects are bioindicators of environmental quality in a Conservation Unit
Provedor de dados: 39
Autores: Santana,André Portugal; Isaias,Rosy Mary dos Santos.
Galls are well distributed across the World and among plant families. Their diversity can support the status of conservation of an area as an urban park, once inventories are presented. These inventories also help to understand the morphological patterns of the galls, based on their most common shape, color, host botanical families, inducers and galled organs. This study is about an inventory of galls at Parque Estadual Serra Verde, Brazil. This conservation unit is an urban park strongly anthropized in a transition area of Cerrado and Mata Atlântica. Galls from four different trails were observed, and collected monthly during one year. The terminology morphospecies was used to distinguish the galls because the identification of the inducers were not...

Several ecological hypotheses try to explain geographical patterns in biodiversity. The Metabolic Theory of Ecology (MTE) predicts that temperature is the main determinant of richness patterns for ectothermic organisms and that the relationship between richness (lnS) and temperature (1/kT) is a linear relationship with angular coefficient (b) near -0.65. This study tested the MTE for continental zooplankton diversity in 63 lakes in Brazil. Copepoda, Cladocera and Rotifera, as well as the three groups combined, showed different patterns from that predicted by MTE, with b values equal to 0.871, 0.516, 0.720 and 0.901, respectively. Temperature explains 12.7% of the richness of Copepoda, 5.3% of Cladocera, 6.7% of Rotifera, and 11.4% of all zooplankton groups...

Engineering biodiversity as a model for the species conservation
Provedor de dados: 42
Autores: RECH,ELIBIO L.
Abstract: Early humans have domesticated plant and animal species based on ancient empirical concepts (Darwin 1868, 1876). In 1886, Mendel established a new paradigm of hereditary laws (Mendel 1866, 1870, 1950) based on genotypic and phenotypic traits of cross-compatible species, establishing a complex breeding technology that is currently utilized for the development of most food and livestock-derived products. Recently, studies on deciphering the double-helical structure (Watson and Crick 1953a, b) and how to restrict DNA (Arber 2012) have established the foundation of recombinant DNA technology. A new era is paving the way for genetic manipulation of important traits among all the kingdom’s organisms, allowing for the development of innovative and...

Abstract  Amazonian biodiversity is increasingly threatened due to the weakening of policies for combating deforestation, especially in Brazil. Loss of animal and plant species, many not yet known to science, is just one among many negative consequences of Amazon deforestation. Deforestation affects indigenous communities, riverside as well as urban populations, and even planetary health. Amazonia has a prominent role in regulating the Earth’s climate, with forest loss contributing to rising regional and global temperatures and intensification of extreme weather events. These climatic conditions are important drivers of emerging infectious diseases, and activities associated with deforestation contribute to the spread of disease vectors. This review...

Autores: LAVOREL,SANDRA; LEBRETON,JEAN-DOMINIQUE; MAHO,YVON LE.
Abstract: In the present context of concerns for biodiversity, the French Academy of Sciences produced in 2017 a report entitled “Mechanisms of adaptation of biodiversity to climate change and their limits”. We briefly review here the production process and structure of the report, and summarize its conclusions and recommendations. The conclusions emphasize the role of habitat fragmentation in the expected impact of climate change on biodiversity, in particular for organisms with limited dispersal abilities, and the disparities in species responses which must be taken to understand the future of species assemblages (“communities”) under different scenarios of climate change. The recommendations cover the organization of biodiversity research and monitoring...

Land use drives change in amazonian tree species
Provedor de dados: 42
Autores: VIEIRA,IMA CÉLIA G.
Abstract: The Amazonian rainforest has been subjected to exceptionally high rates of land use change (LUC), primarily for pasture. We present here an analysis of the impact of LUC on trees from studies made in Pará state. LUC results in drastic declines in native species richness, changes species composition and impacts community resilience and ecosystem services provided by the Amazonian rainforest. Given that secondary forests are expanding in Amazonia we argue that this regrowth forest should be taken into account when planning conservation in this region.

Fishes of the Amazon: diversity and beyond
Provedor de dados: 42
Autores: VAL,ADALBERTO LUIS.
Abstract: The Amazon basin houses a particular group of freshwater organisms, whose study tells the geological history of the region, how biological diversity was shaped, how it is maintained, and what it hides. The fish of the Amazon is represented by more than 3,000 known species distributed from the basal groups up to the more specialized ones. This species richness hides a diversity of adaptations that are dispersed at all levels of the biological organization. In this summary of the conference delivered at the Brazil-France Bilateral Symposium, held in Manaus in 2018, we describe two aspects of the hidden world of adaptive diversity: adaptations to changes in dissolved oxygen and the abilities of the Rio Negro fish to face acidic and ion-poor waters...

Provedor de dados: 42
Autores: SILVA,GLÁUCIA ALVES E; SIQUEIRA,JOSÉ O.; STÜRMER,SIDNEY L.; MOREIRA,FATIMA M.S.
ABSTRACT Arbuscular mycorrhizal fungi provide several ecosystem services, including increase in plant growth and nutrition. The occurrence, richness, and structure of arbuscular mycorrhizal fungi communities are influenced by human activities, which may affect the functional benefits of these components of the soil biota. In this study, 13 arbuscular mycorrhizal fungi isolates originating from soils with different land uses in the Alto Solimões-Amazon region were evaluated regarding their effect on growth, nutrition, and cowpea yield in controlled conditions using two soils. Comparisons with reference isolates and a mixture of isolates were also performed. Fungal isolates exhibited a wide variability associated with colonization, sporulation, production of...

Sandy beaches: state of the art of nematode ecology
Provedor de dados: 42
Autores: MARIA,TATIANA F.; VANAVERBEKE,JAN; VANREUSEL,ANN; ESTEVES,ANDRÉ M.
ABSTRACT In this review, we summarize existing knowledge of the ecology of sandy-beach nematodes, in relation to spatial distribution, food webs, pollution and climate change. We attempt to discuss spatial scale patterns (macro-, meso- and microscale) according to their degree of importance in structuring sandy-beach nematode assemblages. This review will provide a substantial background on current knowledge of sandy-beach nematodes, and can be used as a starting point to delineate further investigations in this field. Over decades, sandy beaches have been the scene of studies focusing on community and population ecology, both related to morphodynamic models. The combination of physical factors (e.g. grain size, tidal exposure) and biological interactions...

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...

Autores: FIGUEIREDO,GUILHERME DE T.; STORTI,LUIS FERNANDO; LOURENÇO-DE-MORAES,RICARDO; SHIBATTA,OSCAR A.; ANJOS,LUIZ DOS.
Abstract: Environmental heterogeneity is a factor which can help explain the higher local species richness. The objective of this study was to test if richness and composition of anurans species are related to available microhabitats and landscape type of sampled sites. We assume that a higher number of microhabitats increase environmental heterogeneity and this, in turn, affects species richness of amphibians. We performed the study in the Mesophytic Semideciduous Forest, a vegetation type within Atlantic Forest Domain. Between October 2010 and February 2011, we sampled 23 water bodies located in the agricultural, forest, and urban landscapes. The species richness was determined using survey at breeding sites methodology, and the availability of...

The use of microsatellite markers in Neotropical studies of wild birds: a literature review
Provedor de dados: 42
Autores: MOURA,RENAN F.; DAWSON,DEBORAH A.; NOGUEIRA,DENISE M.
ABSTRACT Despite extensive habitat fragmentation, the Neotropical region possesses 30% of the world´s bird species. Microsatellites have remained one of the most popular genetic markers and have been used in ecological and conservation studies since the 1990’s. We conducted a literature review comparing the number of papers published from January 1990 to July 2015 that used microsatellite markers for studies of wild birds in the Neotropical region, USA and some European countries. We assigned the articles to three categories of studies: population genetics, animal behavior/kinship analysis and the development of species-specific bird microsatellite markers. We also compared the studies in the Neotropics that used heterologous versus species-specific...

This study aimed to develop a Geographic Information System (GIS), for storage of information and geographic location of apiaries in eight counties in western Paraná; study the local flora; the land used; and the honey productivity in the harvest of 2010 in two of these areas: Marechal Cândido Rondon and Santa Helena. In order to do so we used the software SPRING, delimiting a radius of action of bees of three kilometers around the apiaries. We interviewed and registered 126 beekeepers with 383 apiaries. By using the images we selected areas with greater and lower overlap of hives in Marechal Cândido Rondon (144 and 44 hives, respectively) and Santa Helena (165 and 40 hives, respectively), in a three kilometers radius, selecting 15 colonies in each area,...

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...

Insect taxonomy in species-rich countries: the way forward?
Provedor de dados: 44
Autores: Mound,Laurence A.
There are two extremes in taxonomic behavior - publishing quickly as new taxa become available, and waiting a lifetime in the hope of publishing results that cannot be faulted. Neither of these extremes meets the needs of contemporary biologists in furthering our understanding of the evolution and maintenance of biological diversity. Part of the reason for these extremes is our failure to define suitable objectives for taxonomy. Instead of emphasising the units of biological diversity, we should concentrate on investigating patterns, structural, biological, ecological, temporal, and geographical, because it is these patterns that will generate novel ideas about the evolutionary history of organisms, and that will be most likely to be of interest to the...

Provedor de dados: 49
Autores: Penariol,Leiza; Bicudo,Hermione Elly Melara de Campos; Madi-Ravazzi,Lilian.
The use of open or closed traps in order to standardize the drosophilid collection is still a matter of discussion among researchers. In this paper, comparative data of drosophilid collections, using open and closed traps are presented. The collections were made monthly, during one year, in one fragment of a semidecidual forest located in the São Paulo State, Brazil. The efficiency of the traps was evaluated by the use of community descriptors: population abundance and richness and diversity of species. Closed traps were more efficient than the open ones in relation to the population abundance and the species richness, indicating their adequacy for standardization of drosophilid collection in studies of biodiversity and seasonality.

In this study we have attempted to answer whether there is correspondence between aquatic macroinvertebrate communities and the typological classification of white and clean-water streams in western Amazonia lowlands. We worked within two distinct hydrographic basins: Moa River catchment (clear-water streams) and Azul River catchment (white-water streams) in Serra do Divisor National Park, Acre State, Brazil, sampling 10 streams in each basin. A total of 2,952 individuals were collected, distributed among 134 taxa. Our results show that macroinvertebrate communities, at genus as well as family level, are in concordance to a priori classifications that distinguish between white and clear water streams. The main implication of our results for biomonitoring...

In southeastern Brazil, the remnant Cerrado areas have suffered intense destruction, and presently less than 2% of Cerrado natural vegetation remain in São Paulo state. Virtually no detailed study on Cerrado snakes was carried out in this region. The Itirapina region has one of the last well preserved remnants of open cerrado in São Paulo state. Our purpose in this work was the study of natural history and composition of the Cerrado snakes of Itirapina region. We performed an extensive field sampling combining six sampling methods in Estação Ecológica de Itirapina...

Abstract: We present here an embracing freshwater fish inventory of the Parque Nacional dos Lençóis Maranhenses and adjacent areas, reporting 49 fish species, 33 of which were identified accurately at the species level, representing ten orders and 25 fish families that range from obligate freshwater to estuarine organisms. This number of species is much larger than two previous studies for the park, each reporting just 12 and 33 fishes occurring on freshwater environments. Among the 49 freshwater species recorded in this study, 14 are new records for the Parque Nacional dos Lençóis Maranhenses, and just one corresponds to an introduced species. Some of the 14 new records in the Parque Nacional dos Lençóis Maranhenses, cited above, as well as some of the 16...

Autores: Silva-Junior,Luiz Constantino; Santos,Sérgio Ricardo; Macedo,Márcio Chagas; Nunan,Gustavo Wilson; Vianna,Marcelo.
Abstract: A total of 1,471 specimens of 16 species of flatfishes (Pleuronectiformes) were caught during 48 sampling campaigns between July 2005 and June 2007 at ten stations in Guanabara Bay, Rio de Janeiro, Brazil. Paralichthyidae was the dominant family, with Etropus crossotus as the dominant species. The outer stations, especially those on the western side of the lower estuary, were distinguished as a result of their higher abundance of flatfishes and number of species. The spatial distribution of E. crossotus and its population structure indicate that this species is an estuarine resident despite the apparent reduction in its area of occupation within the estuarine complex. Among the other species, nine were classified as marine stragglers (Achirus...

Cerambycidae (Insecta: Coleoptera) of the Parque Natural Municipal de Porto Velho, Rondônia, Western Amazon, Brazil
Provedor de dados: 49
Autores: Souza,Diego de Santana; Silva,Alexandre de Almeida e.
Cerambycidae is one of the largest families of beetles and it is estimated that there are about 25,000 species of longhorned beetles in the world. However, little is known about the distribution of many species in some regions, including the Amazon. The longhorned beetles are indispensable in the ecological chain, contributing mostly to the recycling of dead wood in forest. The present study is an inventory of the Cerambycidae of the Parque Natural Municipal de Porto Velho, Rondônia, Brazil. Insects were sampled from June 2008 to May 2009 using Malaise and light traps. A total of 61 species were identified, of which 33 are new records for Rondônia and one for Amazon region, i.e., Anisopodus melzeri Gilmour, 1965.

The Middle Jaguaribe River region is a poorly sampled area in the Caatingas domain, located in the eastern Ceará State, northeastern Brazil. The Brazilian government agencies considered this region as a priority area for conservation and inventories. In order to fill this biodiversity knowledge gap, we conducted a ten-day rapid inventory of the anuran fauna from April 11 to 20, 2014, surveying different physiognomies of the region. We recorded 19 anuran species belonging to five families: Bufonidae (2), Hylidae (5), Leptodactylidae (9), Microhylidae (2) and Odontophrynidae (1). Most inventories of Caatinga amphibians published to date have been conducted inside protected areas and/or of high altitude (mesic areas known as "brejos de altitude"). The list we...

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...

Abstract: The knowledge about the richness and distribution of Brazilian dragonflies is still being unveiled. Over the years, inventories, reviews, and descriptions have been made. These contributions, apart from the taxonomic value, also provide valuable data on the occurrence of species and their distributions, which are rarely accompanied by notes about natural history and behavior. Keeping this legacy in mind, we collected dragonflies between 2011 and 2019 in Minas Gerais state, which resulted in the registration of 90 species, 41 genera and 11 families. Our results also increase distribution data, an important tool for conservation actions, and provide additional information about habitat and biology of species.

Abstract Treehopper assemblages were sampled in four semi-arid areas of caatinga in Northeast Brazil during the rainy seasons of 2016 and 2017, using three different capture methods. The areas are located in two Ecoregions of the Caatinga: “Depressão Sertaneja Setentrional” (Northern Sertaneja Depression) and “Planalto da Borborema” (Borborema Plateau). A total of 2,394 individuals of 43 species were sampled, corresponding to approximately 87% of the mean estimated species richness for all four areas. The species richness varied among the areas from 14 to 21, while the abundance of individuals ranged from 129 to 1860. Eighteen species were shared among areas, of which only Enchenopa eunicea, Sundarion sp. 1, Ceresa vitulus and Erosne parvula occurred in...

Synopsis of the knowledge on the Brazilian aplacophorans (Mollusca: Caudofoveata &amp;amp; Solenogastres)
Provedor de dados: 49
Autores: Passos,Flávio Dias; Miranda,Marcel Sabino; Corrêa,Paulo Vinicius Ferraz.
Abstract: Aplacophorans are well known as exclusively marine benthic molluscs with a vermiform body covered by aragonitic sclerites (also called spicules), whose species are widely distributed from the sublittoral down to the abyss. Currently, only nine species are known from Brazil (one Solenogastres and eight Caudofoveata), but these very few records are no longer a reflection of an existing low diversity. Sampling in deep waters has been conducted recently in oil-rich areas of the Brazilian coast, and the museum collections have now many aplacophoran lots. There is a need to learn about and/or install some microscopical facilities in Brazilian institutions, to form expertise for the investigations on these generally small animals. With studies on...

DNA barcoding and traditional taxonomy unified through Integrative Taxonomy: a view that challenges the debate questioning both methodologies
Provedor de dados: 49
Autores: Pires,Amanda Ciprandi; Marinoni,Luciane.
The taxonomic crisis, emphasized in recent years, is marked by the lack of popularity (lack of interest in taxonomy) and financial incentives to study biodiversity. This situation, coupled with the issues involved with the necessity of knowing many yet undiscovered species, has meant that new technologies, including the use of DNA, have emerged to revitalize taxonomy. Part of the scientific community, however, has rejected the use of these innovative ideas. DNA barcoding has especially been the target of numerous criticisms regarding its application, as opposed to the use of morphology. This paper aims to highlight the inconsistency of the debate involving DNA versus morphology, since there is a proposal for the integration of traditional taxonomy and DNA...

Autores: Aidar,M.P.M.; Martinez,C.A.; Costa,A.C.; Costa,P.M.F.; Dietrich,S.M.C.; Buckeridge,M.S.
Plants grown in elevated CO2 environments may exhibit photosynthetic acclimation or down regulation, which is characterised by reduced rates of photosynthesis. In most cases of CO2-induced photosynthetic acclimation, the reduced rates of photosynthesis were still higher than those detected in plants growing at ambient CO2 concentrations. In this work we present a study on the behaviour of seedlings of Hymenaea courbaril, a late secondary/climax species that is one of the most important trees in mature tropical forests of the Americas. After germination, the seedling of H. courbaril increases its rate of growth due to the mobilisation of massive amounts of a storage cell wall polysaccharide (xyloglucan) from its cotyledons. In our experiments, germinated...

Autores: Martinelli,Luiz Antonio; Filoso,Solange.
Brazil has a unique position in the world. It is one of the few countries that can be one of the most important producers of food, fiber and biofuel and at the same time maintain its mega biodiversity endowment and vital ecosystems services properly running. This is a challenge that only can be achieved by recognizing the importance of agribusiness sector to the Brazilian economy, but also that ecosystems have limits and we should not endless expand agriculture in the name of "development". Ecosystem services have to be recognized also as a "development" to be kept for the next generations. Agriculture only exists where ecosystems are able to maintain its basic functioning. Therefore, a well preserved nature it is the most precious asset of agriculture.

The main aim of this study was to assess the diversity of four stream algal divisions (Cyanobacteria, Chlorophyta, Ochrophyta and Rhodophyta) by comparing results obtained with taxonomic distinctness index and diversity patterns of previous studies. The data were obtained from a study made in 1000 stream segments in North American biomes. The taxonomic arrangement of the taxa was created from species to division level in order to obtain the taxonomic tree, which is used in taxonomic distinctness index. The results of taxonomic distinctness index showed that stream macroalgal diversity was different from that commonly found. Herein, Ochrophyta was the division with the highest diversity, whereas in previous studies Chlorophyta has been in the first...

Autores: Gomes,Diego Ferreira; Sanches,Nathalie Aparecida Oliveira; Sahm,Lucas Henrique; Gorni,Guilherme Rossi.
Abstract Oligochaeta is one of the most common and abundant taxon in continental aquatic fauna. However, knowledge of their distribution in Brazilian ecosystems is still incomplete and fragmented. Thus, the aim of this study was to develop an inventory of aquatic oligochaetes in the Extractive Reserve of Lake Cuniã in the State of Rondônia, Brazil. Collections of data were performed during the dry (August 2015) and rainy seasons (February 2016). The sediment samples were collected near the lakeside region using the kick sampling method and a kick-net sampler (mesh size of 0.25mm). This paper provides a catalog with 12 taxon from a total of 383 specimens, distributed into two families: Naididae (95.08%) and Opistocystidae (4.92%). The Pristininae subfamily...

BIOTA/FAPESP, Brazil's model program for assessing global biodiversity
Provedor de dados: 49
Autores: Staley,James T.
Brazils state of São Paulo ranks among the few governments that has recognized the importance of biodiversity. It has successfully launched Biota as part of its FAPESP program in biology. The Biota program has been in operation for three years now, long enough to pose questions about its promise. The questions I will try to address here are: What attributes of the Biota progam have allowed it to succeed where others have failed? Can the Biota program serve as a global model for biodiversity efforts?

Provedor de dados: 50
Autores: Londoño-Cruz,Edgardo.
ABSTRACT Holothurians correspond to 20-25 % of all known species of echinoderms. In the Colombian Pacific, 34 species have been recorded, of which 11 have been recorded on Gorgona Island. This is the first report of the lion’s paw sea-cucumber Euapta godeffroyi on the island. The specimen was collected by scuba diving in the subtidal coralline patch known locally as El Arrecifito del Muelle, at a depth of approximately 2 m. It was about 80 cm long and between 2 and 3 cm in diameter. The ossicles of the body wall basically correspond to anchors and anchor plates; the latter have tiny ramifications at the base of the central axis. The present report fills a gap in the distribution of this species for the Tropical Eastern Pacific.

LA CLASE CAUDOFOVEATA (MOLLUSCA) EN EL MAR CARIBE COLOMBIANO*
Provedor de dados: 50
Autores: Gracia C.,Adriana; Fontalvo,Erlenis; Gámez,Luis Carlos.
Five classes of marine mollusks, including Gastropoda, Bivalvia, Cephalopoda, Scaphopoda, and Polyplacophora, have been recorded inhabiting the Colombian Caribbean Sea. Other classes with a basal position within the phylum such as Caudofoveata and Solenogastres have remained overlooked, as a result of their body shape (worm-like with no shell), small sizes (Caudofoveata 1.5 to 140 mm length), and limited taxonomic information for identifications. The presence of Caudofoveata species on the continental margin of the Colombian Caribbean Sea was evidenced through several studies conducted by Invemar between 2007 and 2012. Samples were collected from localities between Gulf of Morrosquillo and La Guajira, in a bathymetrical range from 3 to 1010 m depth. These...

Sugarcane is an important agricultural product of Brazil, with a total production of more than 500 million tons. Knowledge of the bacterial community associated with agricultural crops and the soil status is a decisive step towards understanding how microorganisms influence crop productivity. However, most studies aim to isolate endophytic or rhizosphere bacteria associated with the plant by culture-dependent approaches. Culture-independent approaches allow a more comprehensive view of entire bacterial communities in the environment. In the present study, we have used this approach to assess the bacterial community in the rhizosphere soil of sugarcane at different times and under different nitrogen fertilization conditions. At the high taxonomic level, few...

The diversity of aquatic Hyphomycetes in South America
Provedor de dados: 58
Autores: Schoenlein-Crusius,Iracema Helena; Grandi,Rosely Ana Piccolo.
Aquatic Hyphomycetes, also named Ingoldian or freshwater fungi, constitute a group of anamorphic fungi that are typically aquatic, producing tetraradiate, sigmoid or spherical conidia on submerged plant debris (leaf litter, petioles, bark, etc.). Mainly occurring in lotic systems, these fungi are considered to be one of the most active groups of organisms in the decomposition of leaf litter, and play a crucial role in the trophic chain. In South America, aquatic Hyphomycetes are mentioned for Argentina, Brazil, Chile, Ecuador, Peru and Venezuela, totalizing the report of about 90 species. Almost all studies are taxonomical, some with proper drawings and complete descriptions, but no keys have been provided yet, nor there is a specific culture collection...

Illumina-based analysis of endophytic bacterial diversity of tree peony (Paeonia Sect. Moutan) roots and leaves
Provedor de dados: 58
Autores: Yang,Ruixian; Liu,Ping; Ye,Wenyu.
ABSTRACT Diverse communities of bacteria inhabit plant tissues and those bacteria play a crucial role for plant health and growth. Tree peony (Paeonia Sect. Moutan) is known for its excellent ornamental and medicinal values as Chinese traditional plant, but little is known about its associated bacterial community under natural conditions. To examine how endophytic bacteria in tree peony vary across tissues and cultivars, PCR-based Illumina was applied to reveal the diversity of endophytic bacteria in tree peony. A total of 149,842 sequences and 21,463 operational taxonomic units (OTUs) were obtained. The OTU abundance of roots was higher than leaves across other three cultivars except for ‘Kinkaku’ and ‘Luoyanghong’. The community was composed of five...

Autores: Akhtar,Nasrin; Ghauri,Muhammad A.; Iqbal,Aamira; Anwar,Munir A.; Akhtar,Kalsoom.
Culturable bacterial biodiversity and industrial importance of the isolates indigenous to Khewra salt mine, Pakistan was assessed. PCR Amplification of 16S rDNA of isolates was carried out by using universal primers FD1 and rP1and products were sequenced commercially. These gene sequences were compared with other gene sequences in the GenBank databases to find the closely related sequences. The alignment of these sequences with sequences available from GenBank database was carried out to construct a phylogenetic tree for these bacteria. These genes were deposited to GenBank and accession numbers were obtained. Most of the isolates belonged to different species of genus Bacillus, sharing 92-99% 16S rDNA identity with the respective type strain. Other...

Microbial diversity in Brazilian mangrove sediments: a mini review
Provedor de dados: 58
Autores: Ghizelini,Angela Michelato; Mendonça-Hagler,Leda Cristina Santana; Macrae,Andrew.
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...

Halophiles are excellent sources of enzymes that are not only salt stable but also can withstand and carry out reactions efficiently under extreme conditions. The aim of the study was to isolate and study the diversity among halophilic bacteria producing enzymes of industrial value. Screening of halophiles from various saline habitats of India led to isolation of 108 halophilic bacteria producing industrially important hydrolases (amylases, lipases and proteases). Characterization of 21 potential isolates by morphological, biochemical and 16S rRNA gene analysis found them related to Marinobacter, Virgibacillus, Halobacillus, Geomicrobium, Chromohalobacter, Oceanobacillus, Bacillus, Halomonas and Staphylococcus genera. They belonged to moderately halophilic...

Provedor de dados: 58
Autores: Li,Shi Lin; Lin,Qiang; Li,Xin Ran; Xu,Hui; Yang,Yun Xi; Qiao,Dai Rong; Cao,Yi.
Microbial lipids, which are also known as single cell oils (SCO), are produced by oleaginous microorganisms including oleaginous bacteria, yeast, fungus and algae through converting carbohydrates into lipids under certain conditions. Due to its unique environment having extremely low temperature and anoxia, the Tibetan Plateau is amongst the regions with numerous rare ecotypes such as arid desert, salt marsh, alpine permafrost, hot spring, and lawn. By using a rapid, convenient screening method, we identified 31 strains of oleaginous microorganisms from different habitats in the Tibetan Plateau, which include wetlands, lawn, hot spring, alpine permafrost, and saline-alkali soil. Molecular identity analysis showed that they belong to 15 different species, 7...

From ecosystems to human welfare: the role and conservation of biodiversity
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...
