Changes in the phytoplankton of Lake Planetario after a restoration process
Provedor de dados: 66
Autores: Ehrenhaus,Constanza; Vigna,María Susana.
Lake Planetario is an urban recreational lake that suffered a Microcystis aeruginosa bloom in March 1999. At the same time the birds and fishes that inhabited the lake died, probably affected by microcystin, hepatotoxin that some strains of Miycrocyistis produce. The City of Buenos Aires requested Aguas Argentinas to restore the lake. Restoration tasks included treatment of sediments and pumping of water from a brackish aquifer. For one year, monthly samples were taken with a phytoplankton net, the qualitative and quantitative composition of the phytoplankton were studied, and physicochemical data were collected. The structure and composition of the phytoplankton were studied and revealed that due to the turbulence caused by the pumping of water, the...

Autores: Shepherd, Brenda; Jasper National Park; Brenda.Shepherd@pc.gc.ca; Whittington, Jesse; Banff National Park; Jesse.Whittington@pc.gc.ca.
Corridor restoration is increasingly being used to connect habitat in mountainous areas where rugged topography and increasing human activity fragment habitat. Wolves (Canis lupus) are a conservation priority because they avoid areas with high levels of human use and are ecologically important predators. We examined how corridor restoration through a golf course changes the distribution of wolves and their prey in Jasper National Park, Alberta, Canada. We followed and recorded wolf paths in the snow both within the corridor and in the surrounding landscape before and after a corridor was re-established. Track transects were used to estimate prey abundance and snow depths, and trail counters measured human activity. We compared resources on wolf paths to...

Autores: Fischer, A. Paige; School of Natural Resources and Environment, University of Michigan; apfisch@umich.edu.
Although people and organizations in the Great Lakes region, USA take seriously their role as stewards of natural resources, many lack capacity to fulfill that role in a meaningful way. Stepping into that gap, The Stewardship Network (TSN) envisions &amp;#8220;a world of empowered, connected communities caring for land and water, now and forever,&amp;#8221; and fulfills that vision through its mission to &amp;#8220;connect, equip, and mobilize people and organizations to care for land and water in their communities.&amp;#8221; TSN uses a scalable model of linked local and regional capacity building, science communication, civic engagement, and on-the-ground stewardship activities to achieve these goals. The model engages local and regional groups in an...

Although few successful examples of large-scale adaptive management applications are available to ecosystem restoration scientists and managers, examining where and how the components of an adaptive management program have been successfully implemented yields insight into what approaches have and have not worked. We document five key lessons learned during the decade-long development and implementation of the Comprehensive Everglades Restoration Plan (CERP) Collaborative Adaptive Management Program that might be useful to other adaptive management practitioners. First, legislative and regulatory authorities that require the development of an adaptive management program are necessary to maintain funding and support to set up and implement adaptive...

Weed Control as a Rationale for Restoration: The Example of Tallgrass Prairie
Provedor de dados: 7
Autores: Blumenthal, Dana M; University of Minnesota; dblumenthal@npa.ars.usda.gov; Jordan, Nicholas R; University of Minnesota; perr0128@tc.umn.edu; Svenson, Elizabeth L; University of Minnesota; esvenso1@swarthmore.edu.
The potential weed control benefits of ecological restoration are rarely cited and largely unstudied. Nevertheless, the nature of many restoration target communities, i.e., diverse, late-successional communities, suggests that restoration may control weeds and that the invasibility of plant communities may decrease with both diversity and successional age. Given the high cost of weed control in nonagricultural land, weed control benefits could be a strong incentive for restoration efforts. We examined the cumulative effects of restoration on weed populations 7 yr after tallgrass prairie restoration on a Minnesota sand plain. The numbers and biomass of volunteer weeds were compared among randomized plots with (1) no restoration, (2) prairie seed addition,...

Oyster reefs provide coastal societies with a vast array of ecosystem services, but are also destructively harvested as an economically and culturally important fishery resource, exemplifying a complex social-ecological system (SES). Historically, societal demand for oysters has led to destructive and unsustainable levels of harvest, which coupled with multiple other stressors has placed oyster reefs among the most globally imperiled coastal habitats. However, more recent studies have demonstrated that large-scale restoration is possible and that healthy oyster populations can be sustained with effective governance and stewardship. However, both of these require significant societal support or financial investment. In our study, we explored relationships...

Stream restoration often aims to enhance fisheries by improving stream conditions for target fish species. However, river restoration has a potential impact on a variety of ecosystem services. Among stakeholders, the emerging expectations about restoration attain different priorities. How well these expectations are met influences social perceptions of success or failure. Although public support for restoration is known to have a significant impact on the sustainability and overall success of restoration, social aspects are rarely considered in this context. To address these issues, we conducted a questionnaire study among the residents and fishermen of three recently restored rivers in Finland. Results indicate that both user groups highly supported the...

Resilience and Restoration of Lakes
Provedor de dados: 7
Autores: Carpenter, Stephen R; University of Wisconsin-Madison; srcarpen@wisc.edu; Cottingham, Kathryn L; ; cottingh@nceas.ucsb.edu.
Lake water quality and ecosystem services are normally maintained by several feedbacks.  Among these are nutrient retention and humic production by wetlands, nutrient retention and woody habitat production by riparian forests, food web structures that cha nnel phosphorus to consumers rather than phytoplankton, and biogeochemical mechanisms that inhibit phosphorus recycling from sediments.  In degraded lakes, these resilience mechanisms are replaced by new ones that connect lakes to larger, regional economi c and social systems.  New controls that maintain degraded lakes include runoff from agricultural and urban areas, absence of wetlands and riparian forests, and changes in lake food webs and biogeochemistry that channel phosphorus to blooms of nuisance...

Increased population sizes of Double-crested Cormorants (Phalacrocorax auritus) and small-bodied (&amp;#60;15 cm total length) yellow perch (Perca flavescens) have occurred at Lac la Biche, Alberta, Canada, since fisheries collapsed the walleye (Sander vitreus) population. A walleye restoration program was introduced in 2005, but uncertainty around the ecosystem&amp;#8217;s response to management made it difficult to evaluate program success. This study used 40 variations of Ecopath with Ecosim models representing ecosystem conditions over 200 years to test the potential for multiple attractors, i.e., possible ecosytem states, in a large lake ecosystem. Results suggest that alternate stable states, defined by walleye-dominated and cormorant-dominated...

We look to a particular social-ecological system, the restoration community in Rhode Island, USA and the rivers, wetlands, marshes, and estuaries they work to protect, to draw connections between communication, community involvement, and ecological restoration project success. Offering real-world examples drawn from interviews with 27 local, state, federal, and nonprofit restoration managers, we synthesize the mechanisms that managers found effective to argue that the communication employed by resource managers in each phase of the restoration process, in prioritization, implementation, and monitoring, and for garnering broad-based support, shapes the quality of public engagement in natural resources management, which, in turn, can impact the stakeholder,...

The Fate of Coho Salmon Nomads: The Story of an Estuarine-Rearing Strategy Promoting Resilience
Provedor de dados: 7
Autores: Koski, K V.; The Nature Conservancy Alaska Field Office, Juneau, Alaska, USA; kkoski@tnc.org.
The downstream movement of coho salmon nomads (age 0), conventionally considered surplus fry, has been an accepted characteristic of juvenile coho salmon for the past 40 to 50 yr. The fate of these nomads, however, was not known and they were assumed to perish in the ocean. Several studies and observations have recently provided new insights into the fate of nomads and the role of the stream-estuary ecotone and estuary in developing this life history strategy that promotes coho resilience. Chinook and sockeye salmon have developed the ocean-type life-history strategy to exploit the higher productivity of the estuarine environment and migrate to the ocean at age 0. Nomad coho can acclimate to brackish water, and survive and grow well in the stream-estuary...

The relevance of the boundary concept to ecological processes has been recently questioned. Humans in the post-industrial era have created novel lateral transport fluxes that have not been sufficiently considered in watershed studies. We describe patterns of land-use change within the Potomac River basin and demonstrate how these changes have blurred traditional ecosystem boundaries by increasing the movement of people, materials, and energy into and within the basin.  We argue that this expansion of ecological commerce requires new science, monitoring, and management strategies focused on large rivers and suggest that traditional geopolitical and economic boundaries for environmental decision making be appropriately revised.

Managing the Resilience of Lakes: A Multi-agent Modeling Approach
Provedor de dados: 7
Autores: Janssen, Marco A; Indiana University; maajanss@indiana.edu; Carpenter, Stephen R; University of Wisconsin-Madison; srcarpen@wisc.edu.
We demonstrate an approach for integrating social and ecological models to study ecosystem management strategies. We focus on the management of lake eutrophication. A model has been developed in which the dynamics of the lake, the learning dynamics of society, and the interactions between ecology and society are included. Analyses with the model show that active learning is important to retain the resilience of lakes. Although very low levels of phosphorus in the water will not be reached, active learning reduce the chance of catastrophic high phosphorus levels.

In the last 200 yr, more than 80% of the land in the U.S. Corn Belt agro-ecosystem has been converted from natural perennial vegetation to intensive agricultural production of row crops.  Despite research showing how re-integration of perennial vegetation, e.g., cover crops, pasture, riparian buffers, and restored wetlands, at strategic landscape positions can bolster declining regional ecosystem functions, the amount of land area devoted to row crop production in the Corn Belt continues to increase.  As this region enters a time of fast-paced and uncertain reorganization driven by the emerging bioeconomy, changes in land use will continue to take place that will impact the resilience of the Corn Belt&amp;#8217;s linked social and ecological systems for...

Demonstration Restoration Measures in Tributaries of the Vindel River Catchment

Autores: Holmqvist, Daniel; Vindel River Fishery Advisory Board; daniel.holmqvist@lycksele.se.
Some ecological restoration projects include elements of trial and error where new measures are repeatedly tried, evaluated, and modified until satisfactory results are achieved. Thereafter, the resulting methods may be applied on larger scales. A difficult step is judging whether developed &amp;#8220;best-practice&amp;#8221; methods have become reasonably ecologically functional or whether further experimentation &amp;#8220;demonstration&amp;#8221; methods can lead to yet better results.

Ecologists have developed terminology to distinguish ecosystems based on the degree of human alteration. To this end, ecosystems can be characterized as &amp;#8220;novel ecosystems,&amp;#8221; &amp;#8220;impacted ecosystems,&amp;#8221; or &amp;#8220;designed ecosystems,&amp;#8221; depending on the role of human management in ecosystem development and effects on ecosystem properties.

Management actions to protect endangered species and conserve ecosystem function may not always be in precise alignment.  Efforts to recover the California Ridgway&amp;#8217;s Rail (Rallus obsoletus obsoletus; hereafter, California rail), a federally and state-listed species, and restoration of tidal marsh ecosystems in the San Francisco Bay estuary provide a prime example of habitat restoration that has conflicted with species conservation.  On the brink of extinction from habitat loss and degradation, and non-native predators in the 1990s, California rail populations responded positively to introduction of a non-native plant, Atlantic cordgrass (Spartina alterniflora).  California rail populations were in substantial decline when the non-native Spartina...

We investigated vegetation responses in terms of canopy, ground-layer diversity, and ecological species groups using two restoration treatments at two degraded oak barren and savanna sites in central Wisconsin, USA. The two restoration models tested were (1) process-only, which reintroduced fire in the form of prescribed burning, and (2) structural manipulation, which used prescribed burning following selective timber removal. Both methods have been widely promoted, debated, and investigated in the fire-prone ecosystems of western North America, but they have not been studied in midwestern ecosystems. Vegetation was monitored in permanent quadrats prior to and following treatment applications. All treatment responses were compared against trends at control...

Resilience, Flexibility and Adaptive Management - - Antidotes for Spurious Certitude?
Provedor de dados: 7
Autores: Gunderson, Lance; Emory University; lgunder@emory.edu.
In many cases, a predicate of adaptive environmental assessment and management (AEAM) has been a search for flexibility in management institutions, or for resilience in the ecological system prior to structuring actions that are designed for learning. Many of the observed impediments to AEAM occur when there is little or no resilience in the ecological components (e.g., when there is fear of an ecosystem shift to an unwanted stability domain), or when there is a lack of flexibility in the extant power relationships among stakeholders. In these cases, a pragmatic solution is to seek to restore resilience or flexibility rather than to pursue a course of broad-scale, active adaptive management. Restoration of resilience and flexibility may occur through novel...

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.

The Apalachicola Bay, Florida, eastern oyster (Crassostrea virginica) industry has annually produced about 10% of the U.S. oyster harvest. Today&amp;#8217;s simple individual-operator, hand-tonging, small-vessel fishery is remarkably similar to the one that began in the 1800s. Unprecedented attention is currently being given to the status of oyster resources in Apalachicola Bay because this fishery has become central to the decision making related to multistate water disputes in the southeastern United States, as well as millions of dollars in funding for restoration programs related to the Deepwater Horizon oil spill. The oyster fishery collapsed in 2012, leading to large economic losses and community concerns over the current and future status of oyster...

Since the mid-20th century, Mediterranean lagoons have been affected by eutrophication, leading to significant changes in primary producers. In the early 2000s, management actions have been implemented to reduce nutrient inputs with the aim to achieve a good ecological status as requested by the EU water framework directive. As a result of these actions, a sharp decline in nutrient loads has been recorded in several lagoons leading to an oligotrophication of the water column. The analyses of a long-term data set (1998-2015) of 21 polyhaline and euhaline lagoons with contrasting trophic status allowed us to infer a general scheme for the changes in macrophyte assemblages during the oligotrophication process. Placing hypertrophic and oligotrophic conditions...

Oyster reefs are among the most threatened marine habitats globally. In Europe, oyster reefs have been extirpated from most locations within their historical range. Active restoration of the native oyster (Ostrea edulis) in Europe has grown substantially in recent years. In sharing experiences between oyster restoration projects in Europe at the Native Oyster Restoration Alliance conference, NORA2, in Edinburgh in May 2019, it became apparent that a number of similar barriers are experienced. This study identified the top 40 questions, which, if answered, would have the greatest influence on the policy and practice of oyster restoration in Europe. Initially 71 people were consulted across 28 institutions and 11 European countries to generate 194 questions....

The growing awareness of the negative impacts of the degradation of the water quality in coastal lagoons because of eutrophication has resulted in public action aiming at the reduction of the nutrient loadings into these lagoons. Hence, some of these coastal lagoons are currently undergoing ecological restoration and have shown a clear improvement of their water quality linked to decreasing phytoplankton biomass in the last 10 years. However, the response of the benthic macrophytes appears more complex, particularly by showing non-linear behaviour. By using complementary approaches including statistical analyses of long-term observations (1998-2015) and in situ measurements, this thesis aims to describe the dynamics of the macrophytes in space and time and...

The European flat oyster (Ostrea edulis) is an ecosystem engineer that provides important biogenic reef habitat with associated ecosystem functions and services. Most stocks have been commercially exploited and degraded; some are functionally extinct. Ecological restoration now aims to recover these degraded, damaged or destroyed ecosystems. Availability of seed oysters and substrate for successful larval recruitment has been identified as a major limiting factor for restoration projects in Europe. In substrate‐limited areas, restoration approaches have to involve the restoration of suitable substrates. The present study provides an evaluation of such potential substrate types. Various categories were investigated through hatchery and/or field experiments:...

Rapport de mission International Conference on Shellfish Restoration, 2011, Stirling (Ecosse)
Provedor de dados: 5
Autores: Mazurie, Joseph.
The 14th International Conference on Shellfish Restoration (ICSR) comes this year to the United Kingdom for the first time in its 26 years history. The conference will be held at the University of Stirling in the heart of Scotland and its title and theme will be “Shellfish: our undervalued resource”. The theme of the conference, “Shellfish: our undervalued resource”, reflects the UK perception of shellfish as something that is good to eat, often in upmarket restaurants. Shellfish fisheries and aquaculture are indeed a very important part of the UK economy; shellfish reefs however form an ecosystem that provides myriad benefits (“ecosystem services”) many of which have been lost through acute fishing pressures, disease, pollution and other factors. On a...

Mining impacts will affect local populations to different degrees. Impacts range from removal of habitats and possible energy sources to pollution and smaller-scale alterations in local habitats that, depending on the degree of disturbance, can lead to extinction of local communities. While there is a shortage or even lack of studies investigating impacts that resemble those caused by actual mining activity, the information available on the potential long-lasting impacts of seabed mining emphasise the need for effective environmental management plans. These plans should include efforts to mitigate deep-sea mining impact such as avoidance, minimisation and potentially restoration actions, to maintain or encourage reinstatement of a resilient ecosystem.

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...

Autores: Andersson, Andreas J.; Venn, Alexander A.; Pendleton, Linwood; Brathwaite, Angelique; Camp, Emma; Cooley, Sarah; Gedhill, Dwight; Koch, Marguerite; Maliki, Samir; Manfrino, Carrie.
The Caribbean and Western Atlantic region hosts one of the world’s most diverse geopolitical regions and a unique marine biota distinct from tropical seas in the Pacific and Indian Oceans. While this region varies in human population density, GDP and wealth, coral reefs, and their associated ecosystem services, are central to people’s livelihoods. Unfortunately, the region’s reefs have experienced extensive degradation over the last several decades. This degradation has been attributed to a combination of disease, overfishing, and multiple pressures from other human activities. Furthermore, the Caribbean region has experienced rapid ocean warming and acidification as a result of climate change that will continue and accelerate throughout the 21st century....

ABSTRACT Tree establishment in pasture areas can be inhibited, at least in part, by exotic grasses allelopathy and this can represent an important limitation by changing the patterns of both germination and seedling growth of tree species. This study aims to evaluate the allelopathic potential of Urochloa brizantha and U. decumbens on germination, growth and metabolism of Guazuma ulmifolia seedlings. We performed bioassays evaluating the effect of the crude ethanol extract and semipurified fractions (hexane fraction, ethyl acetate fraction and ethanol-water fraction) of U. brizantha and U. decumbens using completely randomized design, with four concentrations (0, 250, 500, 1,000 mg L-1) and four replications. The variables analyzed were germination...

Factors Influencing Private Landowner  Restoration Investment Decisions in Coastal Louisiana
Provedor de dados: 31
Autores: Dedah,   Cheikhna O.; Kazmierczak,   Richard F., Jr.; Keithly,   Walter R., Jr.
Coastal wetland loss has been a major problem in Louisiana, exceeding 1.2 million acres over the last century alone. Although federal, state, and local efforts have attempted to combat this loss from a public perspective, little has been done to encourage private landowners to maintain and protect their coastal lands.  This paper investigates the factors that influence private landowners to invest in coastal wetland restoration and maintenance activities in Louisiana.  We surveyed private coastal landowners to determine their general socioeconomic characteristics, attitudes toward risks, attitudes toward wetland conservation, current uses of landholdings, and previous investments in wetland restoration and maintenance projects. Using this survey data, an...

AN ECONOMIC ASSESSMENT OF WETLAND MITIGATION IN NORTHWEST MINNESOTA
Provedor de dados: 31
Autores: Sip,   Robert L.; Leitch,   Jay A.; Meyer,   Aaron J.
The economic efficiency of wetland mitigation in Minnesota's Red River Valley was examined using the Minnesota Routine Assessment Method on ten wetland case studies to rate the functions of impacted and replacement wetlands.  Secondary sources were used to assign dollar values to wetland functions of impacted and replacement wetlands.  Mitigation costs for projects ranged from $279 to $4,171 per acre.  Estimated annual social values ranged from $207 to $1,027 per acre for impacted wetlands and from $268 to $927 per acre for replacement wetlands.  Social values of replacement wetlands exceeded the social value of impacted wetlands in seven cases. Values of replacement wetlands were 1.8 to 4 times greater than the values of impacted wetlands due to 2-to-1...

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

Autores: Mactaggart,   Barbara; Bauer,   Johannes; Goldney,   David; Rawson,   Andrew.
This paper addresses some implications our limited understanding of the swampy meadow landform has on agricultural production and sustainable water management. The ecological and hydrological consequences of current water management practices have lead to a revaluation of natural approaches as an alternative to instream engineering solutions. One such approach would be the restoration/rehabilitation of the swampy meadow. These landforms act as buffering agents for floods and droughts, allow for the re-hydration of the floodplains, and have further positive effects on enhancing biodiversity and improving agricultural productivity outcomes. In this paper we examine the many confusing terms used to label the swampy meadow and postulate that this confusion,...

Response of vegetation to sheep dung addition in a degraded Cerrado area
Provedor de dados: 91
Autores: Teixeira,Danilo S.; Rezende,Andreia A.; Lannes,Luciola S.
ABSTRACT Cerrado is the second largest biome in Brazil and is classified as a biodiversity hotspot. The establishment of hydroelectric power stations in Brazil originated degraded areas due to the removal of soil for construction of dams, in which native vegetation sometimes fails to reestablish due to the bad soil conditions. Sheep excrete most of the nutrients they ingest, such as phosphorus, calcium, potassium and nitrogen. This study aimed at investigating whether sheep dung contributes to the improvement of soil quality and stimulates the process of ecological succession in areas affected by the construction of the hydroelectric power station of Ilha Solteira. Four areas were selected, located at the Experimental Farm of Unesp Ilha Solteira/SP, and...

The reconstitution of soil fertility is essential in the process of pasture restoring, liming being the first action to be taken in this direction. The liming recommendation for pastures needs more technical information as the application method and rate. A field experiment was carried out to evaluate the liming and fertilization practices to restore a degraded Brachiaria decumbens pasture. The following factors were studied: liming method (incorporated in soil by disking or not); level of base saturation (40, 50 or 80%) and lime type (55, 70 or 90 of ECC). Liming and fertilization (NPK and micronutrients) increased both the forage yield and its root system, these being more evident in the second year, even using the same rates of lime and fertilizer used...

Provedor de dados: 39
Autores: Brandes,Arno Fritz das Neves; Albuquerque,Rafael Perpetuo; Moraes,Luiz Fernando Duarte de; Barros,Cláudia Franca.
ABSTRACT The tree Piptadenia gonoachantha is widely used in forestry and in forest restoration projects, which require methods for evaluating tree growth. Long-term studies are necessary to determine patterns and detect changes in species growth rhythms. Tree ring analysis provides a precise method for determining age and documenting long-term growth trends in tropical tree species. The present study evaluated the periodicity of tree ring formation and radial growth dynamics of P. gonoachantha from a population of known age in the Poço das Antas Biological Reserve. Two radii from six trees were sampled using non-destructive methods. Tree rings were counted and measured to estimate age and to calculate diametric increment. All samples had 16 tree rings,...

Breeding system and pollination of Pleroma trichopodum DC. (Melastomataceae): a potential species for the restoration of Atlantic Forest in southern Brazil
Provedor de dados: 39
Autores: Malucelli,Tiago Simões; Maia,Fabiano Rodrigo; Varassin,Isabela Galarda.
ABSTRACT Plant-pollinator interactions and their reproductive implications are of central importance to the organization of plant populations and communities in restoration areas. We studied the breeding system and flower visitors of Pleroma trichopodum, a pioneer species of the Atlantic Forest. We attempted to answer three questions: (1) Is P. trichopodum dependent on pollinators and mates for reproduction? (2) What are the pollinators of P. trichopodum? (3) Do tree flower-density and flowering-tree density of P. trichopodum enhance the visitation rate of focal trees and their flowers? We tested the breeding system through pollination treatments. We performed focal observations on 10 trees and analyzed the relationship between tree and flower visitation...

ABSTRACT This paper records the first report of Megastigmus transvaalensis Hussey (Hymenoptera: Torymidae) in Brazilian peppertree, Schinus terebinthifolius Raddi (Anacardiaceae) drupes in Sorocaba, state of São Paulo, Brazil. This wasp is an invasive species and was found damaging S. terebinthifolius drupes in urban areas (35.0±15.8%), natural forests (21.5±10.2%) and restoration areas (15.8±8.4%). The bio-ecology and damage caused by M. transvaalensis in the S. terebinthifolius drupes warrants further study focused upon the management of this phytophagous wasp. Megastigmus transvaalensis has a potential to be disseminated throughout Brazil and is posing a threat to the natural regeneration of S. terebinthifolius in the native forests and restoration...

Restoration of Atlantic Forests is receiving increasing attention because of its role in both biodiversity conservation and carbon sequestration for global climate change mitigation. This study was carried out in an Atlantic Forest restoration project in the south-central region of São Paulo State - Brazil to develop allometric equations to estimate tree biomass of indigenous tree species in mixed plantations. Above and below-ground biomass (AGB and BGB, respectively), stem diameter (DBH: diameter at 1.3 m height), tree height (H: total height) and specific wood density (WD) were measured for 60 trees of 19 species. Different biomass equations (linear and nonlinear-transformed) were adjusted to estimate AGB and BGB as a function of DBH, H and WD. For...

The role of avian frugivores on germination and potential seed dispersal of the Brazilian Pepper Schinus terebinthifolius
Provedor de dados: 49
Autores: D'Avila,Graziele; Gomes-Jr,Antonio; Canary,Ana Carolina; Bugoni,Leandro.
Frugivorous birds play a key role in seed dispersal and establishment of a range of plant species, including invasive weeds, such as the Brazilian Pepper Schinus terebinthifolius. The potential of seed dispersal of Schinus by birds with varied feeding behaviours was studied through seed-viability tests and germination experiments using seeds obtained from birds in the field and birds kept in captivity. It was found that seeds collected after gut passage in five bird species in the field had higher proportion of germination as well as higher germination rates compared to the control seeds. Viability of seeds ingested by the Blue-and-yellow Tanager Thraupis bonariensis, which mandibulates seeds before ingesting, was significantly lower than control seeds,...

Establishing Acacia salicina under dry Mediterranean conditions: The effects of nursery fertilization and tree shelters on a mid-term experiment with saline irrigation
Provedor de dados: 118
Autores: Oliet,Juan A; Planelles,Rosa; Artero,Francisco; Domingo-Santos,Juan M.
The restoration of dry lands in the Mediterranean is a challenging task because harsh abiotic conditions hamper the counteraction of feed-back degradation processes. Active restoration through planting must be performed to deter this process. In this study, we tested the influence of mineral nutrition in the nursery (two formulations of controlled release fertilizer at two rates each) and tree protection after planting (by using tube shelters) on the nine-year performance of Acacia salicina irrigated with low-quality (saline) water. The overall survival at the end of the study period was 58.2%, with the electrical conductivity of the soil saturation extract reaching 5.4 dSm-1 after nine years. The survival and growth (in height) were greater for seedlings...
