Collaborative Monitoring of Production and Costs of Timber Harvest Operations in the Brazilian Amazon
Provedor de dados: 7
Autores: Pokorny, Benno; University of Freiburg; benno.pokorny@waldbau.uni-freiburg.de.
Timber companies and policy makers in the Brazilian Amazon urgently need financial information on forest management. Results from a few experiments, case studies, and surveys have been groundbreaking, but are insufficient. A strategic partnership between timber companies and research organizations is needed to generate additional information. This paper presents a tool for monitoring production and costs of forest operations to facilitate such collaboration. The tool provides useful information for companies and, at the same time, generates reliable data for research. Selected results are presented on production, capacity, and costs to demonstrate the usefulness of the information that can be generated. These results are based on the first 2 years of...

In this article, we discuss how to monitor the structural and functional attributes of old growth, as well as its associated plant communities and wildlife, both to determine the possible need for treatment and to assess post-treatment progress toward desired conditions. Monitoring can be used to detect conditions (or agents) that threaten existing old growth and also to document indicators of healthy, functioning old-growth systems.

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...

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...

Every day, the challenges to achieving conservation grow.  Threats to species, habitats, and ecosystems multiply and intensify.  The conservation community has invested decades of resources and hard work to reduce or eliminate these threats.  However, it struggles to demonstrate that its efforts are having an impact. In recent years, conservation project managers, teams, and organizations have found themselves under increasing pressure to demonstrate measurable impacts that can be attributed to their actions.  To do so, they need to answer three important questions: (1) Are we achieving our desired impact?; (2) Have we selected the best interventions to achieve our desired impact?; and (3) Are we executing our interventions in the best possible manner?  We...

The Challenge of Collecting and Using Environmental Monitoring Data
Provedor de dados: 7
Autores: Biber, Eric; University of California, Berkeley; ebiber@law.berkeley.edu.
The monitoring of ambient environmental conditions is essential to environmental management and regulation. However, effective monitoring is subject to a range of institutional, political, and legal constraints, constraints that are a product of the need for monitoring to be continuous, long lived, and well matched to the resources being studied. Political pressure or myopia, conflicting agency goals, the need for institutional autonomy, or a reluctance of agency scientists to pursue monitoring all may make it difficult for ambient monitoring to be effectively undertaken. Even if effective monitoring data is gathered, it may not be used in decision making. The inevitable residual uncertainty in monitoring data allows stakeholders to contest the use of...

Insights into integrating cumulative effects and collaborative co-management for migratory tundra caribou herds in the Northwest Territories, Canada
Provedor de dados: 7
Autores: Gunn, Anne; ; gunnan@telus.net; Russell, Don; ; don.russell@ec.gc.ca; Greig, Lorne; ESSA Technologies Ltd.; lgreig@essa.com.
Globally, many migratory mammals are facing threats. In northern Canada, large annual ranges expose migratory caribou to an array of human activities, including industrial exploration and development. Recognition that responses to human activities can accumulate for caribou is long-standing, but is heightened by recent declines in caribou abundance. For example, since the mid-1990s, the Bathurst herd has declined by approximately 90%, leading to severe harvest restrictions. More mines are being proposed and developed across the herd&amp;#8217;s annual range, raising questions about cumulative effects. Despite progress on assessment techniques, aboriginal groups are expressing strong concerns and frustration about gaps in responsibilities for who should...

Natural Length Scales of Ecological Systems: Applications at Community and Ecosystem Levels
Provedor de dados: 7
Autores: Johnson, Craig R; ; craig.johnson@utas.edu.au.
The characteristic, or natural, length scales of a spatially dynamic ecological landscape are the spatial scales at which the deterministic trends in the dynamic are most sharply in focus. Given recent development of techniques to determine the characteristic length scales (CLSs) of real ecological systems, I explore the potential for using CLSs to address three important and vexing issues in applied ecology, viz. (i) determining the optimum scales to monitor ecological systems, (ii) interpreting change in ecological communities, and (iii) ascertaining connectivity between species in complex ecologies. In summarizing the concept of characteristic length scales as system-level scaling thresholds, I emphasize that the primary CLS is, by definition, the...

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...

Over the past decade, &amp;#8220;Payments for Environmental Services&amp;#8221; (PES) have received a great deal of attention as a natural-resource management approach. We propose a revised definition and framework for PES implementation that focuses on the use of positive incentives as the philosophy behind PES and conditionality as the method for influencing behaviors. We note the importance of additionality of PES interventions to justify their value in a wider context. Finally, we highlight the need to understand the local institutional context in terms of the characteristics of buyers, sellers, and their relationship for implementation to be effective. Our framework acts as a platform to begin examining how the variety of options for structuring PES...

Adaptive Ecosystem Management in the Pacific Northwest: a Case Study from Coastal Oregon
Provedor de dados: 7
Autores: Gray, Andrew N; U.S. Forest Service Pacific Northwest Research Station; agray01@fs.fed.us.
Adaptive ecosystem management has been adopted as a goal for decision making by several of the land management and regulatory agencies of the U.S. government. One of the first attempts to implement ecosystem management was undertaken on the federally managed forests of the Pacific Northwest in 1994. In addition to a network of reserve areas intended to restore habitat for late-successional terrestrial and aquatic species, "adaptive management areas" (AMAs) were established. These AMAs were intended to be focal areas for implementing innovative methods of ecological conservation and restoration and meeting economic and social goals. This paper analyzes the primary ecological, social, and institutional issues of concern to one AMA in the Coast Range in...

Around the world, the decreasing health of coral reef ecosystems has highlighted the need to better understand the processes of reef degradation. The development of more sensitive tools, which complement traditional methods of monitoring coral reefs, may reveal earlier signs of degradation and provide an opportunity for pre-emptive responses. We identify new, sensitive metrics of ecosystem processes and benthic composition that allow us to quantify subtle, yet destabilizing, changes in the ecosystem state of an inshore coral reef on the Great Barrier Reef. Following severe climatic disturbances over the period 2011-2012, the herbivorous reef fish community of the reef did not change in terms of biomass or functional groups present. However, fish-based...

How to Track Adaptation to Climate Change: A Typology of Approaches for National-Level Application

Jody; UCLA Fielding School of Public Health ; jody.heymann@ph.ucla.edu.
The need to track climate change adaptation progress is being increasingly recognized but our ability to do the tracking is constrained by the complex nature of adaptation and the absence of measurable outcomes or indicators by which to judge if and how adaptation is occurring. We developed a typology of approaches by which climate change adaptation can be tracked globally at a national level. On the one hand, outcome-based approaches directly measure adaptation progress and effectiveness with reference to avoided climate change impacts. However, given that full exposure to climate change impacts will not happen for decades, alternative approaches focus on developing indicators or proxies by which adaptation can be monitored. These include systematic...

Conflict and indecision are hallmarks of environmental policy formulation. Some argue that the requisite information and certainty fall short of scientific standards for decision making; others argue that science is not the issue and that indecisiveness reflects a lack of political willpower. One of the most difficult aspects of translating science into policy is scientific uncertainty. Whereas scientists are familiar with uncertainty and complexity, the public and policy makers often seek certainty and deterministic solutions. We assert that environmental policy is most effective if scientific uncertainty is incorporated into a rigorous decision-theoretic framework as knowledge, not ignorance. The policies that best utilize scientific findings are defined...

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...

The governance outcomes of natural resource co-management have been neither systematically monitored nor rigorously assessed. We identified system attributes and key variables that could form the basis for monitoring the governance dimension of adaptive co-management. A methodology for collaboratively monitoring these system attributes and key variables was tested in four localities in South Africa.  Our results suggest that creating the conditions that facilitate self-organization, and particularly cross-scale institutional linkages, is the major challenge facing attempts to initiate adaptive co-management. Factors requiring greater attention include community perceptions of support from outside agencies, access to long-term funding for adaptive decision...

Estimation of alluvial recharge in the semiarid
Provedor de dados: 70
Autores: Andrade,Tafnes S.; Montenegro,Suzana M. G. L.; Montenegro,Abelardo A. de A.; Rodrigues,Diogo F. B.
In areas where there is irrigated agriculture, the recuperation of water reserves in alluvial aquifers may occur preferentially due to precipitation. Recharging can be evaluated from variation information of water depth measured in piezometers or observation wells. Thus, the aim of this research is to study the recharge in the alluvial aquifer formed by the Mimoso temporary stream in the semiarid region of Pernambuco (PE), Brazil, using the method of the fluctuation of the water level. This system is typical on the Brazilian Northeast semiarid region, using groundwater for domestic supply and for irrigation on small scale agriculture. Monthly potentiometric levels and rainfall data were used. The selected period for the study, from January 2002 to October...

Two evident peaks during the cold (February) and warm (July–August) periods were revealed, which was connected with differences in development level and phytoplankton vertical distribution, which were stipulated in turn, by water hydrostructure peculiarities in the natural stratification layers. “Winter” bioluminescence maximum in the surface layer was stipulated by the development of C. fusus; P. divergens; P. oblongum mainly, with the cells volume, maximal in the year. The second one, located in the thermocline layer and lower, was formed, mainly, at the expense of C. fusus...

A 3-year survey was made of several biological markers in mussels (Mytilus edulis) exposed in situ to the oil that came ashore after the wreck of the "Erika" tanker on the Brittany (France) coast in December 1999. The mussel response was assessed using a set of 7 biomarkers, most of them related to the metabolism of organic contaminants. After a series of validation tests, data was evaluated for only 5 biomarkers: acety1cholinesterase (AChE), glutathione S-transferase (GST), catalase (CAT), malondialdehyde (MDA) and deoxyribonucleic acid (DNA) adducts. No significant reductions in GST or CAT levels were observed, levels of DNA adducts and MDA were high during the 6 months immediately following the accident and levels of AChE were significantly lower during...

Developing enduring capacity to monitor ocean life requires investing in people and their institutions to build infrastructure, ownership, and long-term support networks. International initiatives can enhance access to scientific data, tools and methodologies, and develop local expertise to use them, but without ongoing engagement may fail to have lasting benefit. Linking capacity development and technology transfer to sustained ocean monitoring is a win-win proposition. Trained local experts will benefit from joining global communities of experts who are building the comprehensive Global Ocean Observing System (GOOS). This two-way exchange will benefit scientists and policy makers in developing and developed countries. The first step toward the GOOS is...

Marine protected areas and artificial reefs: A review of the interactions between management and scientific studies
Provedor de dados: 5
Autores: Claudet, Joachim; Pelletier, Dominique.
Inshore marine areas host key habitats for the biological cycle of many marine populations, but are subject to strong anthropogenic pressure. Uses of inshore areas are multiple and often give rise to conflicting interests. In this context. marine protected areas (MPAs) and artificial reefs (ARs) are increasingly regarded as interesting management measures, in that they contribute to ecosystem conservation, fisheries sustainability, and because they can be helpful in zoning coastal areas in order to reduce conflicts between users. Beyond these expected benefits, it is important to appraise whether MPAs and ARs meet managers' objectives. This review focuses on the interaction between ecological sciences and management in the purpose of establishing or...

Etude des mortalités ostréicoles de l'hiver 1998/1999 en Baie des Veys. Caractérisation et analyse temporelle des dessalures observées sur les parcs conchylicoles de la baie de Veys depuis 1996.
Provedor de dados: 5
Autores: Ropert, Michel; Kopp, Joel.
The Shellfish Laboratory of Normandy (LCN : Laboratoire Conchylicole de Normandie) observed unusual hydrologic anomalies associated with important oyster mortalities during the winter of 1999. These anomalies were described as sudden salinity variations during the lidal cycle, particularly on the rising tide. Starting in 1996 a multi-parameter probe was used to monitor salinity, temperature and depth every 10 to 20 minutes in the inter-tidal zone. Alter data processing and filtering, two criteria concerning low salinity were chosen : amplitude and duration. Application of a cumulative function (Ibanez et al., 1993) to this time series data treatment showed the 3 year trend (1996-1999). Salinity variation data and climatic data were used in a multivariate...

Underwater video techniques for observing coastal marine biodiversity: A review of sixty years of publications (1952–2012)
Provedor de dados: 5
Autores: Mallet, Delphine; Pelletier, Dominique.
Underwater video techniques are increasingly used in marine ecology studies. Technological progress regarding video cameras, sensors (such as sounders), battery life and information storage make these techniques now accessible to a majority of users. However, diver-based underwater visual censuses, and catch and effort data, remain the most commonly used for observing coastal biodiversity and species. In this paper, we review the underwater video techniques that have been developed since the 1950s to investigate and/or monitor coastal biodiversity. Techniques such as remote underwater video, whether baited or not, diver-operated video and towed video are described, along with corresponding applications in the field. We then analyse the complementary of...

The Mytilos project was carried during the last 3 years (2004-2006) in order to evaluate the level of chemical contamination along the coasts of the western basin of the Mediterranean Sea. Active mussel watch consisted of caged (12 weeks) Mytilus galloprovincialis at 123 stations along the Mediterranean coasts of Spain, France, Italy, North Tunisia, Algeria and Morocco. Results indicated total PAHs levels in the range 22-106 mu g/kg dry weight. All large towns or industrial areas from all countries of the basin were affected. Analysis of the origin of contamination demonstrated mainly a pyrolytic origin except in some areas such as Maddalena, Napoli, Alger, and Cornigliano (Genova). Statistical analysis of the PAHs accumulation data enabled the...

Evaluation of FluoroProbe® performance for the phytoplankton-based assessment of the ecological status of Mediterranean coastal lagoons
Provedor de dados: 5
Autores: Garrido, Marie; Cecchi, Philippe; Malet, Nathalie; Bec, Beatrice; Torre, Franck; Pasqualini, Vanina.
The European Water Framework Directive and several other legislations worldwide have selected phytoplankton for monitoring the ecological status of surface waters. This assessment is a complicated task in coastal lagoons due to their intrinsic variability, prompting moves to use real-time measurements. Here, we tested the ability of the submersible spectrofluorometer FluoroProbe® to accurately estimate the phytoplankton biomass and to efficiently discriminate spectral groups in Mediterranean coastal lagoons, by using sub-surface water samples (n = 107) collected at Biguglia lagoon (Corsica) in different environmental situations (salinity and trophic state) from March 2012 to December 2014. We compared the estimates of biomass and phytoplankton group...

Background  Over the last decade, inventorying and monitoring of marine biodiversity has significantly benefited from the active engagement of volunteers. Although several Citizen Science projects concern tropical reef ecosystems worldwide, none of the existing initiatives has yet specifically focused on their Mediterranean equivalents. Mediterranean coralline reefs, known as “coralligenous”, are bioherms primarily built by calcifying rhodophytes on hard substrates under dim-light conditions; they are considered hotspots of biodiversity and are extremely popular among divers due to their complex structure, conspicuous biological wealth and high aesthetic value. Nevertheless, data on their distribution, structure and conservation status is lacking for...

Autores: Dreves, Luc.
A nuclear power plant is set up at Flamanville (Channel; West coast of the Cotentin). For monitoring studies, one species (or a group of species) has been chosen in each major unit for a reference population dynamics study. Hard bottoms are covered by several species of barnacles. These species present different temperature affinities, and have reached here an equilibrium stage. The recruitment period of Balanus balanoides, the main species, has been determined. A relationship is established between the wintry temperature and the numerical importance of its spring recruitment.

Control of the repeatability of high frequency multibeam echosounder backscatter by using natural reference areas
Provedor de dados: 5
Autores: Roche, Marc; Degrendele, Koen; Vrignaud, Christophe; Loyer, Sophie; Le Bas, Tim; Augustin, Jean-marie; Lurton, Xavier.
The increased use of backscatter measurements in time series for environmental monitoring necessitates the comparability of individual results. With the current lack of pre-calibrated multibeam echosounder systems for absolute backscatter measurement, a pragmatic solution is the use of natural reference areas for ensuring regular assessment of the backscatter measurement repeatability. This method mainly relies on the assumption of a sufficiently stable reference area regarding its backscatter signature. The aptitude of a natural area to provide a stable and uniform backscatter response must be carefully considered and demonstrated by a sufficiently long time-series of measurements. Furthermore, this approach requires a strict control of the acquisition...

Scientific interest in deep-water marine resources has increased dramatically over the last 10-20 years as management bodies have sought advice on how to manage deep-water fisheries and protect deep-water ecosystems. The strengths and weaknesses of the management and monitoring of deep-water stocks, fisheries, and ecosystems in various areas of the world are described, with the objective of informing the EU FP7 DEEPFISHMAN project so that it can fulfill its primary aim, which is to develop strategic options for a short-and long-term management and monitoring ecosystem-based framework for the northeast Atlantic. To provide a baseline, the current monitoring and management regime in the northeast Atlantic is reviewed, followed by a brief description of the...

No more reason for ignoring gelatinous zooplankton in ecosystem assessment and marine management: Concrete cost-effective methodology during routine fishery trawl surveys
Provedor de dados: 5
Autores: Aubert, A.; Antajan, Elvire; Lynam, C.; Pitois, S.; Pliru, A.; Vaz, Sandrine; Thibault, D.
Gelatinous zooplankton, including cnidarians, ctenophores, and tunicates (appendicularians, pyrosomes, salps and doliolids), are often overlooked by scientific studies, ecosystem assessments and at a management level. Despite the important economic consequences that they can have on human activities and on the marine foodweb, arguments often related to the costs of monitoring or their coordination, or simply negligence, have resulted in the absence of relevant monitoring programs. A cost-effective protocol has been applied on trawling from existing fishery surveys conducted by national laboratories in England and France. The testing phase has successfully demonstrated the adequacy of such a tool to sample macro- and mega-zooplankton gelatinous organisms in...

New applications of hydroacoustic methods for monitoring shallow water aquatic ecosystems: the case of mussel culture grounds
Provedor de dados: 5
Autores: Brehmer, Patrice; Gerlotto, François; Guillard, Joelle; Sanguinede, Fabien; Guennegan, Yvon; Buestel, Dominique.
The development of acoustics tools and methods for monitoring anthropized ecosystems represents a new field for the application of acoustics. Monitoring such an environment was not possible with single vertical echo sounders, due to the fact that the artificial structures and the natural targets were not distinguishable. Monitoring data were collected along the French Mediterranean coastline, during five short surveys of mussel culture longline areas. Both the Reson Seabat 6012 multibeam sonar (455 kHz) and the Simrad SR 240 omnidirectional sonar (23.75 kHz) were used for target detection. The former tools allow accurate allocation of the different types of echoes to artefacts, fish schools and scattered fish. The school characteristics collected included...

A bloom of the toxic dinoflagellate Alexandrium tamarense was observed for the first time in Thau iagoon between November and December 1998. Maximum cell concentrations detected in shellfish farming areas (85 000 Cells/1) were high enough to make mussels and clams unsuitable for human consumption (max. 850 ug. STX eq.100 g'1) while toxic levels in oysters did not exceed, or even reach, the international public health threshold established for PSP toxins.  This event, new to French Mediterranean waters, was investigated by both local and national veterinary services and by the Ifremer teams involved in the National Monitoring Network for Phytoplankton and Phycotoxines (Réphy). The chronological and operational description of the event was compared with data...

High resolution mass spectrometry for quantitative analysis and untargeted screening of algal toxins in mussels and passive samplers
Provedor de dados: 5
Autores: Zendong, Suzie Zita; Mccarron, Pearse; Herrenknecht, Christine; Sibat, Manoella; Amzil, Zouher; Cole, Richard B.; Hess, Philipp.
Measurement of marine algal toxins has traditionally focussed on shellfish monitoring while, over the last decade, passive sampling has been introduced as a complementary tool for exploratory studies. Since 2011, liquid chromatography-tandem mass spectrometry (LC-MS/MS) has been adopted as the EU reference method (No.15/2011) for detection and quantitation of lipophilic toxins. Traditional LC-MS approaches have been based on low-resolution mass spectrometry (LRMS), however, advances in instrument platforms have led to a heightened interest in the use of high-resolution mass spectrometry (HRMS) for toxin detection. This work describes the use of HRMS in combination with passive sampling as a progressive approach to marine algal toxin surveys. Experiments...

This paper aims at collating and reviewing all data collected using the ESCA (Ecological Status of Coralligenous Assemblages) index from 2009 to 2018 during different local applications, in order to evaluate at large spatial scale its effectiveness and temporal variability. To this scope, the large-scale response of ESCA to anthropogenic disturbance was tested comparing ESCA values calculated at 42 sites of the Western Mediterranean Sea with the anthropization index. Moreover, the sensitivity of ESCA to punctual human disturbance and the robustness of the index across the natural space and time variability were evaluated. The large spatial scale study showed significant correlation between ESCA and the anthropization index, while very low correlation was...

Development of sequence characterized amplified region markers from intersimple sequence repeat fingerprints for the molecular detection of toxic phytoplankton Alexandrium catenella (Dinophyceae) and pseudo-Nitzschia pseudodelicatissima (Bacillariophyceae) from French coastal waters
Provedor de dados: 5
Autores: Bornet, Benjamin; Antoine, Elisabeth; Francoise, Sylvaine; Marcaillou-le Baut, Claire.
Harmful algal blooms are a serious threat to shellfish farming and human health all over the world. The monitoring of harmful algae in coastal waters originally involved morphological identification through microscopic examinations, which was often difficult unless performed by specialists and even then often did not permit identification of toxic species. More recently, specific molecular markers have been used to identify specific phytoplankton species or strains. Here we report on the use of the intersimple sequence repeat (ISSR) technique to develop specific sequence characterized amplified region markers (SCAR) and to identify with these tools two toxic species in French coastal waters, the diatom Pseudo-nitzschia pseudodelicatissima (Hasle) Hasle and...

This document describes and harmonizes detection methods of diarrheic (DSP) and paralytic (PSP) phycotoxins, for the laboratories of the Direction of Coastal Environment of IFREMER, which work in the framework of the French Phytoplankton and Phycotoxins Monitoring Network. These toxins, produced by a few phytoplankton species which regularly occur in sea water, accumulate in shellfish, which become toxic. Analysis is performed on an extract of digestive gland (DSP), or of total flesh (PSP), of shellfish. The described methods are meuse-tests, which are, at the present time, the only methods available to be used in the framework of a monitoring network. The method for diarrheic toxins is not standardized, with a threshold adapted for monitoring purposes. At...

Marine litter within the European Marine Strategy Framework Directive
Provedor de dados: 5
Autores: Galgani, Francois; Hanke, Georg; Werner, S.; De Vrees, L.
There have been numerous anthropogenic-driven changes to our planet in the last half-century. One of the most evident changes is the ubiquity and abundance of litter in the marine environment. The EU Marine Strategy Framework Directive (MSFD, 2008/56/EC) establishes a framework within which EU Member States shall take action to achieve or maintain good environmental status (GES) of their marine waters by 2020. GES is based on 11 qualitative descriptors as listed in Annex I of the MSFD. Descriptor 10 (D 10) concerns marine litter. As a follow-up to the related Commission Decision on criteria and methodological standards (2010/477/EU) in which 56 indicators for the achievement of GES are proposed, the EC Directorate-General for the Environment, on the...

Indices for assessing coral reef fish biodiversity: the need for a change in habits
Provedor de dados: 5
Autores: Loiseau, Nicolas; Gaertner, Jean-claude.
We present the first representative and quantified overview of the indices used worldwide for assessing the biodiversity of coral reef fishes. On this basis, we discuss the suitability and drawbacks of the indices most widely used in the assessment of coral fish biodiversity. An extensive and systematic survey of the literature focused on coral reef fish biodiversity was conducted from 1990 up to the present. We found that the multicomponent aspect of biodiversity, which is considered as a key feature of biodiversity for numerous terrestrial and marine ecosystems, has been poorly taken into account in coral reef fish studies. Species richness is still strongly dominant while other diversity components, such as functional diversity, are underestimated even...

Whilst both plastic production and inputs at sea have increased since the 1950s, several modelling studies predict a further increase in the coming years in these respective quantities. We compiled scientific literature on trends in marine litter, consisting largely of plastic and microplastics in the ocean, understanding that monitoring programs or assessments for these aspects are varied, frequently focusing on limited components of the marine environment in different locations, and covering a wide spectrum of marine litter types, with limited standardization. Here we discuss how trends in the amounts of litter in the marine environment can be compared with the information provided by models. Increasing amounts of plastic are found in some regions,...

Water quality criteria and monitoring for marine mollusc culture : the French experience
Provedor de dados: 5
Autores: Heral, Maurice; Berthome, Jean-paul.
The impact of the main parameters of water quality which act on the life history of molluscs are presented. Two types of parameters are examined: the first are the physical-chemical parameters as temperature, salinity, turbidity, oxygen concentrations. They can be modified by perturbations directly related to human activities such as management of physical operations, e.g. constructions of dams, dredging for channels or for extraction of materials. Particular attention is given to inputs of nutrients with as consequences eutrophication and depletion of oxygen causing anoxie conditions. Attention will he focussed on some phytoplankton species like Gyrodinium aurelum which can cause mortalities in mollusc shellfish. The action of the main pollutants...

Development of a biologically based environmental quality standard from a long-term benthic monitoring programme in the North Sea
Provedor de dados: 5
Autores: Brown, Ar; Shillabeer, N.
The paper describes the derivation and effectiveness of a benthic macrofauna environmental quality standard (EQS). The EQS is derived from a continuing, long-term (24 years) monitoring programme, designed to determine the effect of mining effluent discharged into coastal waters off the NE coast of England. The area under study is at the Cleveland Potash mine at Boulby. Benthic monitoring began there in 1970 and live years of baseline data were gathered before discharge commenced in 1974. During the course of the monitoring programme (1970-1993) annual surveys have been completed at the discharge point and at more distant reference sites. The complete data set includes results from over 1000 benthic grab samples. The effect of the discharge is clearly...

Autores: Gohin, Francis; Saulquin, Bertrand; Oger-jeanneret, Helene; Lozac' H, L; Lampert, Luis; Lefebvre, Alain; Riou, Philippe; Bruchon, F.
The application of the new Water Framework Directive (WFD) of the European Union will require a dense and frequent monitoring of chlorophyll-a near the coast. Not counting the transitional water bodies located in the vicinity of estuaries, not less than seventy four coastal water bodies have to be monitored along the coast of the French Atlantic continental shelf and the English Channel. All the available data have to be gathered to implement a comprehensive monitoring scheme. To this purpose, we evaluate the capacity of ocean colour imagery to complete the conventional in situ data set collected in coastal networks. Satellite-derived chlorophyll-a concentration is obtained by the application of a coastal Look-Up-Table to water-leaving radiance of the...

Autores: Belin, Catherine.
Different ways are explored for presenting 12 years of data on phytoplankton species and toxins in shellfish collected along the French coast and within the framework of the French Phytoplankton Monitoring Network. The advantages and difficulties of aggregating data in different dimensions are discussed. For example, graphs appear suitable only for restricted areas, while mapping is necessary for results on regional or larger scales. Within each of these broad categories, considerable care is required when identifying the appropriate type of information and presentation.

Microplastics in Seawater: Recommendations from the Marine Strategy Framework Directive Implementation Process
Provedor de dados: 5
Autores: Gago, Jesus; Galgani, Francois; Maes, Thomas; Thompson, Richard C.
Microplastic litter is a pervasive pollutant present in marine systems across the globe. The legacy of microplastics pollution in the marine environment today may remain for years to come due to the persistence of these materials. Microplastics are emerging contaminants of potential concern and as yet there are few recognized approaches for monitoring. In 2008, the EU Marine Strategy Framework Directive (MSFD, 2008/56/EC) included microplastics as an aspect to be measured. Here we outline the approach as discussed by the European Union expert group on marine litter, the technical Subgroup on Marine litter (TSG-ML), with a focus on the implementation of monitoring microplastics in seawater in European seas. It is concluded that harmonization and coherence...

Incentive effect of joint and several liability in fishery cooperatives on regulatory compliance
Provedor de dados: 5
Autores: Bellanger, Manuel; Holland, Daniel S.; Anderson, Christopher M.; Guyader, Olivier.
Cooperative‐based catch share systems can be implemented such that the members of the same fishery cooperative are jointly and severally liable for not exceeding collectively assigned fishing rights. In practice, this means that a regulator can take away catch privileges from an entire cooperative that overruns its collective quota, effectively creating a penalty much larger than what could be recovered with an individual fine. Fishery cooperatives then typically implement their own internal compliance regime that includes monitoring and penalties. This article first reviews compliance practice in cooperative‐based catch share systems by examining the commonalities and differences in the way compliance regimes are structured (observation and reporting...

Metabarcoding on planktonic larval stages: an efficient approach for detecting and investigating life cycle dynamics of benthic aliens
Provedor de dados: 5
Autores: Couton, Marjorie; Comtet, Thierry; Le Cam, Sabrina; Corre, Erwan; Viard, Frédérique.
High-throughput sequencing (HTS) technologies offer new promise to support surveillance programs targeting marine non-indigenous species (NIS). Metabarcoding might surpass traditional monitoring methods, for example through its ability to detect rare species, a key feature in early detection of NIS. Another interest of this approach is the identification of organisms difficult to identify based on morphology only (e.g., early developmental stages), making it relevant in the context of management programs. Because many marine benthic NIS have a biphasic benthopelagic life cycle, targeting their pelagic larval stages in zooplankton may allow early detection and assessment of their establishment and potential spread. We illustrate this approach with an...

Coastal zones inventory by high resolution satellites
Provedor de dados: 5
Autores: Loubersac, Lionel.
The development of tools for assessing impacts on coastal environments is a reality. These impact assessments need both baseline and monitoring studies. Satellite remote sensing data would be useful for coastal inventories (baselines) and monitoring if high spatial and temporal resolutions are yield compatible. An overview of the various sensors that could be used is presented. The constraints linked to the different resolutions are exposed. An example based on Spot simulated data and trends are developed.

Dynamics of an estuarine ecosystem - The Chesapeake Bay experience: Statistical approaches and water quality patterns
Provedor de dados: 5
Autores: Alden, Rw.
A long-term water quality monitoring program has been established in the Virginian waters of the Chesapeake Bay. To date, over eight years of data have been analyzed to characterize spatio-temporal patterns and long-term trends in water quality. Complementary multivariate statistical procedures were employed to define spatial and seasonal patterns, while a series of non-parametric trend analyses were used for determining overall, site-specific, and season-specific long-term trends for water quality variables in the tributaries and mainstem of the Bay. Particular attention was focused on determining the effect of river flow on the trends, because flow rates in some of the tributaries have changed dramatically since the beginning of the monitoring program....

The common mussel Mytilus galloprovincialis was selected as unique biomonitor species to implement a regional monitoring programme, the CIESM Mediterranean Mussel Watch (MMW), in the Mediterranean and Black Seas. As of today, and upon standardization of the methodological approach, the MMW Network has been able to quantify Cs-137 levels in mussels from 60 coastal stations and to produce the first distribution map of this artificial radionuclide at the scale of the entire Mediterranean and Black Seas. While: measured Cs-137 levels were found to be very low (usually &lt;1 Bq kg(-1) wet wt) Cs-137 activity concentrations in the Black Sea and North Aegean Sea were up to two orders of magnitude higher than those in the western Mediterranean Basin. Such effects,...

Surveillance du milieu marin et protection santiaire des coquillages
Provedor de dados: 5
Autores: Renault, Tristan.
Shellfish farming is a major economic activity in the European Union, France being one of the main producing countries. Regulations were introduced to meet society's current expectations in terms of food safety at the fishing, farming and harvesting stages, as weil as during processing and marketing. Toxic algae, pathogens or pollutants may contaminate shellfish products during production and harvesting, partly because of the particular environ mental conditions in which these animais are grown. Monitoring programmes were thus deve/oped to detect the presence of biological and chemical contaminants in coastal waters and in shellfish, and to monitor the food safety of the latter.

Notes on survey-based spatial indicators for monitoring fish populations
Provedor de dados: 5
Autores: Woillez, Mathieu; Rivoirard, Jacques; Petitgas, Pierre.
This paper presents the spatial indicators used in the European project FISBOAT. These are statistics intended to capture spatial patterns of fish populations, using fish density data collected during scientific surveys. To handle diffuse population limits, indicators are designed not to depend on arbitrary delineation of the domain. They characterize the location (centre of gravity and spatial patches), occupation of space (inertia, isotropy, positive area, spreading area and equivalent area) and microstructure. Collocation between different populations is summarized by a global index of collocation. These spatial indicators have the potential to be used in a monitoring system to detect changes in spatial distribution. They could be helpful for relating...

Exploring Environmental DNA (eDNA) to Assess Biodiversity of Hard Substratum Faunal Communities on the Lucky Strike Vent Field (Mid-Atlantic Ridge) and Investigate Recolonization Dynamics After an Induced Disturbance
Provedor de dados: 5
Autores: Cowart, Dominique; Matabos, Marjolaine; Brandt, Miriam; Marticorena, Julien; Sarrazin, Jozee.
Deep ocean hydrothermal vent ecosystems face physical disturbances from naturally occurring volcanic and tectonic activities and are at increasing risk of mineral resource exploitation, raising concerns about the resilience of endemic biological communities. Following destructive events, efficient and rapidly applicable surveys of organisms are required to monitor the state, evolution and a possible return of these ecosystems to their original baseline status. In this study, we explored the environmental DNA (eDNA) approach as a tool (1) to assess biodiversity of benthic communities associated with deep-sea hard substrata and (2) tracked the recolonization dynamics of benthic invertebrate communities living on the Montségur edifice within the Lucky Strike...

Background Applying non-target analysis (NTA) in regulatory environmental monitoring remains challenging—instead of having exploratory questions, regulators usually already have specific questions related to environmental protection aims. Additionally, data analysis can seem overwhelming because of the large data volumes and many steps required. This work aimed to establish an open in silico workflow to identify environmental chemical unknowns via retrospective NTA within the scope of a pre-existing Swiss environmental monitoring campaign focusing on industrial chemicals. The research question addressed immediate regulatory priorities: identify pollutants with industrial point sources occurring at the highest intensities over two time points. Samples from...

Autores: Littaye-mariette, Anne; Mazurie, Joseph.
Since 1989, an homogeneous Crassostrea gigas oyster stock has been distributed once a year on several rearing sites in Brittany (3 populations per site). The main quantitative and qualitative growth descriptors, which reflect water quality effects during the monitoring period, are estimated at the end of each year. The 1989-1992 analysis prompted us to describe various growth responses correlated to biotops: oyster production in open areas influenced by oceanic waters was fairly constant in quality, including size and Polydora sp. infestation. In contrast, oysters in estuarine areas, partly affected by eutrophication (e.g., Aber Benoît, Pen Bé), or with a low carrying capacity, were characterized by weight and Polydora sp. infestation heterogeneity. These...

Autores: Weimerskirch, Henri; Delord, Karine; Barbraud, Christophe; Le Bouard, Fabrice; Ryan, Peter G.; Fretwell, Peter; Marteau, Cedric.
Today albatrosses are threatened worldwide, especially by fishing activities, and many populations are currently in decline. Albatrosses breeding at the French Southern Territories in the south-western Indian Ocean, on the Crozet, Kerguelen and Saint-Paul–Amsterdam island archipelagos, are monitored regularly. This monitoring has been based on a sample of species and sites, and there was a need for an assessment of the population trends for all species at each site. During the past 3 years most populations have been surveyed, allowing an assessment of the trends of albatrosses breeding at the archipelagos of the French Southern Territories over the past 40 years. Wandering Albatrosses show similar trends at all sites within the Crozet and Kerguelen...

Ability of spatial indicators to detect geographic changes (shift, shrink and split) across biomass levels and sample sizes
Provedor de dados: 5
Autores: Rufino, Marta; Bez, Nicolas; Brind'Amour, Anik.
Spatial indicators are widely used to monitor species and are essential to management and conservation. In the present study, we tested the ability of 11 spatial indicators to quantify changes in species’ geographic patterns: (1) spatial displacement of a patch of biomass (‘shift’), (2) a spatial decrease in a patch, accompanied either by a loss of biomass (‘shrink0’) or (3) a relocation of the same biomass (‘shrink1’), and (4) splitting of a patch into smaller patches (‘split’). The geographic changes were simulated by manipulating the spatial distributions of the demersal species (observed during bottom trawl surveys). Hence, the spatial distributions of the latter being used as input data on which the manipulations were done. Additionally, other aspects...

Human and animal enteric caliciviruses in oysters from different coastal regions of the United States
Provedor de dados: 5
Autores: Costantini, V; Loisy, Fabienne; Joens, L; Le Guyader, Soizick; Saif, L.
Food-borne diseases are a major cause of morbidity and hospitalization worldwide. Enteric caliciviruses are capable of persisting in the environment and in the tissues of shellfish. Human noroviruses (HuNoVs) have been implicated in outbreaks linked to shellfish consumption. The genetic and antigenic relatedness between human and animal enteric calliciviruses suggests that interspecies transmission may occur. To determine the occurrence of human and animal enteric calliciviruses in United States market oysters, we surveyed regional markets. Oysters were collected from 45 bays along the United States coast during the summer and winter of 2002 and 2003. Samples were analyzed by reverse transcription-PCR, and results were confirmed by hybridization and...

Autores: Robert, Stephane; Le Moine, Olivier; Lunven, Michel; Caisey, Xavier; Gaffet, Jean-dominique; Le Gall, Erwan; Vasquez, Mickael; Rodriguez, Julien; Detcheverry, Sebastien; Goulletquer, Philippe.
Placopecten magellanicus production in Saint Pierre et Miquelon (NW North Atlantic) has been developed through direct seeding of juveniles on leased areas. However, most of the culture occurs in deep water ranging from 30 to 70 meters, which requires a monitoring by video to facilitate the grow-out and survival evaluation. In August 2008, a submersible leaded structure was connected by a video cable to the surface and observation screen was defined through the video, an altimeter and two lasers. The pictures were recorded on board on hard drive and digital video recorder DVCAM, and data were georeferenced by VIDEONAV software. Analysing the video tapes allows to establish a thematic database on the ground structure, presence or absence of seeded and wild...

The impacts of short-term temporal factors on the magnitude and direction of marine protected area effects detected in reef fish monitoring
Provedor de dados: 5
Autores: Powell, Abigail; Pelletier, Dominique; Jones, Timothy; Mallet, Delphine.
Marine protected areas (MPA) and in particular no-take marine reserves have been identified as important tools for the conservation of reef fish and habitats. A significant challenge of reef fish monitoring is to determine the influence of temporal factors on fish counts. Fish assemblages are dynamic and changes in activity patterns throughout the day can influence the results of surveys. While many monitoring programs account for the impacts of spatial heterogeneity on fish assemblages the effects of short-term temporal variation are less well known. In the present study, we analysed data from 197 video drops inside and outside New Caledonian MPAs and examined temporal variations in various metrics commonly used to monitor marine reserves. In addition to...

Monitoring of trace metal contamination in the Souss estuary (South Morocco) using the clams Cerastoderma edule and Scrobicularia plana
Provedor de dados: 5
Autores: Anajjar, E; Chiffoleau, Jean-francois; Bergayou, H; Moukrim, A; Burgeot, Thierry; Cheggour, M.
Concentrations of seven metals (Cd, Cu, Cr, Pb, Ni, Zn, Hg) were monitored monthly during 2 years in two bivalves, Cerastoderma edule and Scrobicularia plana collected from the Souss estuary (South Morocco) before and after the commissioning of a sewage treatment plant in November 2002. According to trace metals, changes in concentrations were observed mainly in S. plana, characterised by a decrease of Cu, Hg and Pb when Cd was clearly increasing. Conversely, no clear changes were observed in C. edule during the same periods. This study suggests the use of S. plana in the monitoring of trace metal contamination of such coastal marine environments.

Adverse effects of invasive alien species (IAS), or biological pollution, is an increasing problem in marine coastal waters, which remains high on the environmental management agenda. All maritime countries need to assess the size of this problem and consider effective mechanisms to prevent introductions, and if necessary and where possible to monitor, contain, control or eradicate the introduced impacting organisms. Despite this, and in contrast to more enclosed water bodies, the openness of marine systems indicates that once species are in an area then eradication is usually impossible. Most institutions in countries are aware of the problem and have sufficient governance in place for management. However, there is still a general lack of commitment and...

Phycotoxin monitoring in France : risk-based strategy and main results (2006-2008)
Provedor de dados: 5
Autores: Belin, Catherine; Amzil, Zouher.
Toxin monitoring is carried out along the coasts of France by a national network, REPHY, which is the National Monitoring Network for Phytoplankton and Phycotoxins. Sampling strategy differs according to the type of zone coastal or offshore and to the family of toxins. For PSP and ASP toxins, monitoring is based on the detection of toxic phytoplankton species. For lipophilic toxins, a systematic analysis of toxins is performed in risk areas during high risk periods. Experimental monitoring for palytoxins has also been conducted along the Mediterranean coast since 2007. The total number of toxin analyses is in the order of 2500 to 3000 per year. The detailed results for each family of toxins showed that the most frequent toxic events for the period from...

A fisheries acoustic multi-frequency indicator to inform on large scale spatial patterns of aquatic pelagic ecosystems
Provedor de dados: 5
Autores: Trenkel, Verena; Berger, Laurent.
Fisheries acoustic instruments provide information on four major groups in aquatic ecosystems: fish with and without swim bladder (tertiary and quaternary consumers), fluidlike zooplankton (secondary consumers) and small gas bearing organisms such as larval fish and phytoplankton (predominantly primary producers). We entertain that this information is useable to describe the spatial structure of organism groups in pelagic ecosystems. The proposal we make is based on a multi-frequency indicator that synthesises in a single metric the shape of the acoustic frequency response of different organism groups, i.e. the dependence of received acoustic backscattered energy on emitting echosounder frequency. We demonstrate the development and interpretation of the...

Provedor de dados: 5
Autores: Tsangaris, Catherine; Hatzianestis, Ioannis; Catsiki, Vassiliki-angelique; Kormas, Konstantinos Ar; Strogyloudi, Evangelia; Neofitou, Christos; Andral, Bruno; Galgani, Francois.
An integrated approach using biomarkers and contaminant levels in mussels Mytilus galloprovincialis L was employed to assess chemical contamination in Greek coastal waters within the framework of the MYTIMED program. Biomarkers (metallothioneins, glutathione S-transferase, catalase, acetylcholinesterase and RNA:DNA ratio) have been previously described in mussels caged at 14 sites in coastal areas influenced by different types of anthropogenic activities. This study applied a biomarker index, the Integrated Biomarker Response (IBR) to summarize biomarker responses and relate stress levels to concentrations of organochlorine compounds (PCBs, DDTs), polycyclic aromatic hydrocarbons (PAHs), and metals (Cu, Ni, Fe, Zn) measured in the mussel tissues. The IBR...

To reduce the practice of discarding commercially fished organisms, several measures such as a discard ban and extra allowances on top of landings quotas (“catch quota”) have been proposed by the European Commission. However, for their development and successful implementation, an understanding of discard patterns on a European scale is needed. In this study, we present an inter-national synthesis of discard data collected on board commercial, towed-gear equipped vessels operating under six different national flags spanning from the Baltic to the Mediterranean Seas mainly between 2003 and 2008. We considered discarded species of commercial value such as Atlantic cod (Gadus morhua), haddock (Melanogrammus aeglefinus), European hake (Merluccius merluccius),...

Shellfish monitoring for lipophilic phycotoxins in France, recommendation for an updated sampling strategy
Provedor de dados: 5
Autores: Thebault, Anne; Arnich, Nathalie; Belin, Catherine; Neaud-masson, Nadine.
In France, the sampling strategy for the official monitoring of lipophilic phycotoxins in bivalve shellfish relies on the definition of risk areas and high risk periods, during which a systematic weekly analysis of toxins in shellfish is performed. Since 2010, high risk periods are defined as follows: the occurrence of one result above the European regulatory limit (160 μg equivalent okadaic acid/kg shellfish) over the last 3 years leads to that month being considered a high risk period. This definition was established according to a statistical analysis of the official monitoring results for the period 2003-2008, based on the mouse bioassay (MBA) as the official analytical method. As of the 1st January 2010, the MBA has been replaced by LC-MS/MS. In 2014,...

Autores: Witkowski, Fanny.
Coral reefs are among the most diversified ecosystems; structured by comlexe processese. Yet, spatial organization of the diversity of reef fish communities is not well known. The present study, covering the Marine Protected Area of Pouebo (North-East of New Caledonia), takes part of the AMBIO project from IFREMER, which studies spatio-temporal variations of biodiversity by means of High-definition rotatif underwater video systems. In total 1717 individuals from 25 taxonomic families, 56 genus and 145 species were observed. The derived habitat typology of stations distinguishes five habitat classes, which seem to be highly significant for fish species richness and fish density. Results show that biodiversity increases close to the intermediate and the...

The CUSUM out-of-control table to monitor changes in fish stock status using many indicators
Provedor de dados: 5
Autores: Petitgas, Pierre.
One method to assess fish stocks using a suite of indicators is the traffic light approach. In this approach, the time series of the different indicators are mapped on a common colour scale to highlight alerts that occur when indicators cross reference limit values. Until now, however, the procedure has lacked a statistical framework. Here, we propose the cumulative sum (CUSUM) monitoring scheme as a suitable statistical framework. CUSUM is a statistical process control method that detects deviations from a reference mean, according to defined performance criteria. With the CUSUM monitoring scheme, alarm signals can be triggered when indicators cross defined in-control limits that correspond to defined probabilities of false alarm and non-alarm (i.e.,...

Autores: Montereale-gavazzi, Giacomo; Roche, Marc; Degrendele, Koen; Lurton, Xavier; Terseleer, Nathan; Baeye, Matthias; Francken, Frederic; Van Lancker, Vera.
Three experiments were conducted in the Belgian part of the North Sea to investigate short-term variation in seafloor backscatter strength (BS) obtained with multibeam echosounders (MBES). Measurements were acquired on predominantly gravelly (offshore) and sandy and muddy (nearshore) areas. Kongsberg EM3002 and EM2040 dual MBES were used to carry out repeated 300-kHz backscatter measurements over tidal cycles (similar to 13 h). Measurements were analysed in complement to an array of ground-truth variables on sediment and current nature and dynamics. Seafloor and water-column sampling was used, as well as benthic landers equipped with different oceanographic sensors. Both angular response (AR) and mosaicked BS were derived. Results point at the high...

Cadmium and mercury in Seine Estuary flounders and mussels: the results of two decades of monitoring
Provedor de dados: 5
Autores: Nakhle, K; Cossa, Daniel; Claisse, Didier; Beliaeff, Benoit; Simon, S.
The flounder (Platichthys flesus) is a flatfish that inhabits marine coastal environments, especially estuaries. It is an alternative quantitative biological indicator to the common marine mussel (Mytilus spp.), which is currently used as a sentinel species to monitor chemical contamination in numerous monitoring programmes. Findings from two decades of monitoring cadmium (Cd) and mercury (Hg) using both sentinel species in the Seine Estuary (France) are reported. For comparison, time-series of water concentrations for the same two metals at the mouth of the River Seine are given. Cd concentrations in the liver of the fish and in the soft tissue of mussels show similar temporal trends, consistent with the major temporal variations of Cd concentrations...

Marine Protected Areas' (MPAs) and Artificial Reef's (ARs) management requires complex assessment and monitoring programmes, dealing with different sources of variability. We studied and developed experimental designs and analysis methods suited for the establishment of a monitoring of MPAs and ARs. This methodology is developed from existing data sets in the Northwestern Mediterranean. We build multi-criteria indicators allowing a statistically testable diagnosis of the impact of MPAs and ARs on reef fish assemblages. Using ecological performance indicators permits to monitor and to give an image of the assessed system to managers.  It was possible to show the global response of the fish assemblages to the protection by a MPA. This response was evidenced...

Distribution of silver in mussels and oysters along the French coasts: Data from the national monitoring program
Provedor de dados: 5
Autores: Chiffoleau, Jean-francois; Auger, Dominique; Roux, Nathalie; Rozuel, Emmanuelle; Santini, Anne.
Distribution and behavior of many trace elements in the aquatic environment has been well characterized, but little is known about silver (Ag) concentrations in coastal waters, even though this element ranks among the most toxic to marine invertebrates (Calabrese et al., 1977 ; Fisher and Hook, 1997 ; Webb and Wood, 1998). Studies conducted by Flegal et al. (1995), River-Duarte et al. (1999), and Ndung'u et al. (2001), provided the first valuable data on Ag distribution in the oceanic environment, indicating that this element is found in very low concentrations in the dissolved phase. However, although silver concentrations in coastal waters do not reach the nanomolar range (Smith and Flegal, 1993 ; Squire et al., 2002), formation of a stable chloro...

The work presented here aims at comparing monitoring of S-metolachlor, the major pesticide in use in the Arcachon Bay (South West of France, transitional coastal area), by chemical analysis (monthly passive sampling) and contaminant dissipation modeling from sources (Mars-2D model). The global strategy consisted in i) identifying the major sources of S-metolachlor to the Bay, ii) monitoring these sources for 12 months, and iii) comparing modeled data in the Bay based on measured inputs, to chemical measurements made inside the Bay along with the 12-month source monitoring. Results first showed that the major S-metolachlor surface inputs to the Arcachon Bay are mainly from one single source. Modeled and measured data were in good agreement at 5 sites in the...

La pollution chimique marine. Quelles politiques pour une protection durable de l'océan et des mers côtières ?
Provedor de dados: 5
Autores: Marchand, Michel.
The coastal marine environment presents some specificity compared to other aquatic environments: it is both the receiving end of pollution on land and the most biologically rich marine area, where are developing many uses (fisheries and aquaculture, salt production, tourism, thalassotherapy). The coastal zone is therefore vulnerable to chronic chemical pollution and its protection requires research, monitoring and regulation. A dual strategy can be put into place: a preventive approach to avoid placing on the market of toxic substances to humans and the environment, and a retrospective approach based on public policies for the protection and restoration of degraded aquatic environments.

Seafloor instabilities and sediment deformation processes: the need for integrated, multi-disciplinary investigations
Provedor de dados: 5
Autores: Vanneste, Maarten; Sultan, Nabil; Garziglia, Sebastien; Forsberg, Carl Fredrik; L'Heureux, Jean-sebastien.
In this paper, we present the current practice of investigations of seafloor instabilities and deformation processes, based on extensive research conducted over the last years, which sets the scene for future research activities in this field. The mapping of the continental margins and coastal areas with ever increasing resolution systematically reveals evidence of instabilities and deformation processes, both active and palaeo-features. In order to properly assess the hazards and risks related to these features, an integrated and multi-disciplinary approach is essential, but challenging. Such an approach consists of combining field data (geophysics, geology, sedimentology, geochemistry and geotechnical data) with numerical simulations constrained by...

Acetylcholinesterase activity in copepods (Tigriopus brevicornis) from the Vilaine River estuary, France, as a biomarker of neurotoxic contaminants
Provedor de dados: 5
Autores: Forget, Joelle; Beliaeff, Benoit; Bocquene, Gilles.
From April 1997 to June 1998, 14 measurements of acetylcholinesterase (AChE) enzymatic activity were performed with the copepod, Tigriopus brevicornis, collected at five stations in the Vilaine River estuary (South Brittany, France). Simultaneously, four chemical analyses of triazines and one analysis of total pesticides in water were undertaken. AChE activity levels in T brevicornis were compared to the levels measured at a reference site not exposed to effluents from Vilaine River. Results reveal significant differences between AChE activity levels depending on location of stations in the plume of the river with an increasing gradient of activity from the upstream to the downstream stations, thus indicating that neurotoxic contaminants are mainly brought...

A multivariate indicator to monitor changes in spatial patterns of age-structured fish populations
Provedor de dados: 5
Autores: Petitgas, Pierre; Poulard, Jean-charles.
Quantitative analysis of the spatial patterns in age-structured fish populations provides a useful complement to stock assessment methods. The spatial distribution of an age-structured population is characterized by indicators for location, dispersion and aggregation, which are estimated from survey data. The times series of spatial indicators are organised in a 3D data structure with dimensions along indicators, age classes and years. Multi factor analysis (MFA) is applied to quantify the reproducibility in time of the multivariate structure between age classes and indicators. MFA computes the mean annual pattern over the age classes. The deviation around that pattern in each year is also quantified. A multivariate indicator that characterise the spatial...

Abstract  Background: Ruminant feed containing animal byproduct proteins (ABPs) is prohibited in many countries due to its risk of transmitting prion diseases (PD). In most cases the entire herd is sacrificed, which causes great harm to the producer countries by preventing their exportation of ruminant derived-products.  Methods: We used stable isotope ratio mass spectrometry (IRMS) of carbon (13C/12C) and nitrogen (15N/14N) to trace the animal protein in the blood of 15 buffaloes (Bubalus bubalis) divided into three experimental groups: 1 - received only vegetable protein (VP) during 117 days; 2 - received animal and vegetable protein (AVP); and 3 - received animal and vegetable protein with animal protein subsequently removed (AVPR). Groups 2 and 3...

Autores: Doorenweerd, C.; Haren, M.M. van; Schermer, M.; Pieterse, S.; Nieukerken, E.J. van.
We present an interactive key that is available online through any web browser without the need to install any additional software, making it an easily accessible tool for the larger public. The key can be found at http://identify.naturalis.nl/lithocolletinae. The key includes all 86 North-West European Lithocolletinae, a subfamily of smaller moths (“micro-moths”) that is commonly not treated in field guides. The user can input data on several external morphological character systems in addition to distribution, host plant and even characteristics of the larval feeding traces to reach an identification. We expect that this will enable more people to contribute with reliable observation data on this group of moths and alleviate the work-load of taxonomic...

The production and quality of eucalyptus plantations have been studied in areas with different densities of ant nests, being important to estimate losses caused by leaf-cutting ants. The effects of leaf-cutting ant on wood production in differents productivity sites were studied in eucalyptus plantations in the region of Atlantic Forest, Minas Gerais State, Brazil from 2003 to 2006. Data of plots of the continuous forest inventory and data of leaf-cutting ant monitoring in eucalyptus plantations were obtained. Each unitary increment in the area of Atta spp. nests per hectare reduced the wood production of the eucalyptus forest between 0.04 and 0.13 m³.ha-1, resulting in a level of economic damage for leaf-cutting ants between 13.4 and 39.2 m².ha-1, in this...

Autores: Gama,Renata A.; Silva,Eric M.; Silva,Ivoneide M.; Resende,Marcelo C.; Eiras,Álvaro E.
MosquiTRAP™ is a sticky trap specifically designed to capture gravid females of Aedes aegypti (L.) and allows the identification of the mosquito in the field during the inspection of the trap. This study aims to compare this sticky trap to larval and ovitrap surveys for field monitoring of A. aegypti during the dry season. The study was conducted from March to June of 2003 in 20 blocks of the district of Itapoã, Belo Horizonte, MG. The traps were monitored every week while the larval survey was conducted on a monthly basis. The larval index: Premise Index (PI) and Breteau Index (BI) had equal values throughout the experiment (1.72 in the first two months and zero in the last two). The container index (CI) during the first two months was 0.09 and 0.1%,...

Haplotype identification within Spodoptera frugiperda (J.E. Smith) (Lepidoptera: Noctuidae) corn and rice strains from Colombia
Provedor de dados: 82
Autores: Salinas-Hernandez,H; Saldamando-Benjumea,CI.
The fall army worm Spodoptera frugiperda (Smith) is a migratory important pest of corn, sorghum, rice, grass and bermudagrass in North and South America. This species has diverged into two genetically differentiated but morphologically identical strains, "the rice" and "the corn". They have been analyzed by sequencing the genes cytochrome oxydase I, II and ITS1 from populations from the United States and Brazil. However, no such studies were performed in Colombia. In here, we identified 43 haplotypes by sequencing a fragment of the COI gene from 102 individuals, of which 40 had already been identified as the "corn" and "rice" strains or to their hybrids from Tolima, and the rest were collected from corn, cotton, sorghum, grass and rice fields in other...

Arthropod recolonization in the restoration of a semideciduous forest in southeastern Brazil
Provedor de dados: 82
Autores: Pais,Mara P; Varanda,Elenice M.
The use of arthropods for monitoring habitat changes has grown widely in the last decades. In Brazil, however, most of the studies in restored areas have involved only vegetation changes. The present study aimed at investigating recolonization patterns of epigeic arthropods in recently restored sites of semideciduous forests in southeastern Brazil. We compared the community structure of adjoining sites 5, 17, 29 and 36 months old with that at a nearby forest remnant (reference site). We also determined the most abundant species and looked for ecological indicator species of each site age. Arthropods were sampled using pitfall traps, and their assemblages were described and compared with multi- and univariate statistical methods. Species abundance and...

Provedor de dados: 20
Autores: Formoso, M.; Díaz, R.
La región monitoreada, fue objeto de captura comercial de cobo en el país. En 1999 se realizó un monitoreo del área que demostró una merma en los niveles de abundancia de la especie, probablemente debido a una sobre- explotación durante 1998, luego de uana moratoria nacional producto de los resultados de Ferrer y Alcolado (1994), así como un mal manejo y desconocimiento de las áreas de concentración. Esto motivó que el Centro de Investigaciones Pesqueras propusiera una veda total, con un plazo indefinido, hasta tanto se evidenciara una recuperación del recurso. Luego de 10 años de reposo, se visitaron las áreas tradicionales de pesca en el año 2009, que demostró que los niveles de abundancia fueron buenos y sobre la base de un manejo precautorio en cuanto...

Taiwan Island is at the joint of Eurasian Continent and Pacific Plate, under threatening of typhoons and northeasterly strong winds. Consequently, enormous human lives and properties are lost every year. It is necessary to develop a coastal sea-state monitoring system. This paper introduces the coastal sea-state monitoring system (CSMS) along Taiwan coast. The COMC (Coastal Ocean Monitoring Center in National Cheng Kung University) built the Taiwan coastal sea-state monitoring system, which is modern and self-sufficient, consisting of data buoy, pile station, tide station, coastal weather station, and radar monitoring station. To assure the data quality, Data Quality Check Procedure (DQCP) and Standard Operation Procedure (SOP) were developed by the COMC....

Análisis de clasificación de series temporales: el caso de la salinidad en la Ciénaga Grande de Santa Marta
Provedor de dados: 20
Autores: Giraldo-H., R.; Martínez-C., J.; Hurtado-T., L.H.; Zea, S.; Madera-R., E.R.
Se realizó una clasificación numérica de 21 estaciones de monitoreo del sistema laguno -estuarino comprendido por la Ciénaga Grande de Santa Marta y el Complejo Pajarales, de acuerdo a su similaridad en el comportamiento de la salinidad del agua. Se utilizó información quincenal comprendida entre enero de 1987 y octubre de 1991. Debido a la estructura de autocorrelación de los datos fue necesario emplear los modelos ARIMA de series de tiempo en primer lugar, y posteriormente aplicar una técnica de clasificación normal con los coeficientes de la representación infinita AR calculados para cada estación. Los resultados del análisis fueron coherentes con las hipótesis planteadas acerca de la distribución de la variable en el sistema.

The predictability of biological populations and communities: an example from the meiobenthos
Provedor de dados: 27
Autores: Herman, P.M.J.; Heip, C.H.R.
The predictability of temporal changes was analysed in the population density of three meiobenthic copepod species, and for three parameters characterizing this community. For &lt;i&gt;Paranychocamptus nanus&lt;/i&gt; and &lt;i&gt;Tachidius discipes&lt;/i&gt; a large part of the variation in time scales longer than 1 year is explainable as cyclic factors. In &lt;i&gt;P. nanus&lt;/i&gt; clear cycles with periods of 2 years and 1.5 years were found. These cyclic factors can be extrapolated for prediction. In &lt;i&gt;Canuella perplexa&lt;/i&gt; almost all the variation was due to unpredictable long-term drift. Community parameters are generally better predicted than population densities. In our data set total density of the copepods was the best parameter to...

Corredores ecológicos como ferramenta para a desfragmentação de florestas tropicais
Provedor de dados: 190
Autores: Seoane, Carlos Eduardo Sícoli; Diaz, Vinícius Sandri; Santos, Tomaz Longhi; Froufe, Luís Claudio Maranhão.
A expansão do uso e ocupação antrópica do espaço terrestre leva a uma severa fragmentação dos habitats naturais. Corredores ecológicos podem facilitar o deslocamento de organismos entre fragmentos de habitats e têm sido cada vez mais adotados como uma ferramenta para manter e restaurar a biodiversidade. A teoria da metapopulação é uma das bases para os atuais estudos sobre corredores ecológicos. Esses estudos ainda estão pouco desenvolvidos, especialmente em ecossistemas tropicais, carecendo de bases científicas sólidas para apoiar a sua utilidade. No entanto, os efeitos da fragmentação florestal são tão severos que é justificável o planejamento e a execução de medidas que busquem atenuá-las, apesar de não estarem disponíveis resultados de pesquisas que...

The Spanish National Forest Inventory: history, development, challenges and perspectives
Provedor de dados: 190
Autores: Alberdi, Iciar; Cañellas, Isabel; Vallejo Bombín, Roberto.
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...

A national survey on swine health was conducted by the National Animal Health Monitoring System ( NAHMS ) from December 1989 through January 1991. The survey sample was designed in collaboration with the National Agricultural Statistics Service (NASS ) in order to provide inferences about the nation's hog population, 95 percent of which was represented. The program consisted of two parts: the first was a general farm management and policy questionnaire  that was completed by 1,661 producers. The second part of the program was a monitoring phase that took place over a three-month period for each of 712 participating producers. Per litter estimates for the national population showed an average of 9.9 piglets born alive and 8.4 weaned. Estimates attributed 57...

Autores: Alford,   Andrew R.; Clark,   Richard A.; Griffith,   Garry R.
A critical component of the Continuous Improvement and Innovation (CI&amp;I) process described in Paper 4 above is Performance Assessment - analysing and interpreting the results achieved, and not achieved, in relation to the focus and target outcomes. This is made easier if specific Key Performance Indicators (KPIs) are established during Action Design and monitored during Action Implementation. The target outcome for the Measurement, Monitoring and Evaluation (MME) Strategy is to design and implement effective and efficient MME mechanisms that will demonstrate improvements and innovations in individual beef businesses and supply chains and in the broader Australian beef industry.

ORGANIZATIONAL CONSEQUENCES OF EMOTIONAL LABOUR IN MANGENENT

Autores: Lazanyi,   Kornelia.
Emotional labour, as a self-contained field of research, is only three decades old. This study aims to summarize key findings from investigations of the last ten years in an attempt to provide a reference for interpretation of organizational emotions and the organizational aspects of emotional labour. It makes no secret of its aim being to call the attention of anybody dealing with people as workforce that work no longer has only physical or mental aspects, but an emotional dimension as well. Most often this latter dimension lives an independent life. Normally, it is not regulated, tracked, appreciated or rewarded properly, which might send a message to employees that it is not really important. However, emotional labour is a concomitant of most...

Agri-Environmental Program Compliance in a Heterogeneous Landscape
Provedor de dados: 31
Autores: Lankoski,   Jussi E.; Lichtenberg,   Erik; Ollikainen,   Markku.
Heterogeneity of agricultural landscapes may necessitate the use of spatially targeted instrument combinations to implement the social optimum.  But compliance with these policies may require costly enforcement.  This paper examines the design of agri-environmental policies featuring two of the most commonly used instruments, reductions in fertilizer application rates and installation of riparian buffers.  While compliance with buffer strip requirements is verifiable at negligible cost, fertilizer application is only verifiable through costly monitoring.  We derive optimal subsidies for fertilizer reduction and buffer strip set-asides and enforcement strategies for the cases of low and excessive monitoring costs.  An empirical simulation model suggests...

Should we impose emissions taxes that firms evade?
Provedor de dados: 31
Autores: Stranlund,   John K.
Most of the theoretical literature on enforcing environmental policies focuses on situations in which pollution sources are noncompliant. However, some recent work suggests that these situations will very often involve suboptimal policy designs. Thus, the circumstances under which it is efficient to implement policies that do not motivate full compliance appear to be more limited than most of the literature would imply.  In this paper, I identify several circumstances under which regulators may conserve enforcement costs by implementing emissions taxes that firms evade. I demonstrate that a regulator can use a firm’s tax evasion to reduce monitoring effort, but only if its monitoring strategy can be made an increasing function of the firm’s emissions, if...

The Reporting and Support Framework is an integral component of the Measuring, Monitoring and Evaluation (MME) strategy. This framework is designed to capture changes in practices, processes and outcomes in the CI&amp;I partnerships and in beef businesses, partnerships, value chains and the broader Australian beef industry so as to provide support within the CI&amp;I partnerships and to meet project and CRC reporting requirements. Because of the multiple users of the information, and the multiple environments in which it is expected to be used, the BPP reporting and support framework has been a difficult framework to develop. There have been several versions that have been adapted and improved over time, but we hope that it is now sufficiently flexible to...

Hidden action, risk aversion and variable fines in agri-environmental schemes
Provedor de dados: 31
Autores: Ozanne,   Adam; White,   Benedict.
This note analyses the design of agri-environmental schemes for risk-averse producers whose input usage is only observable by costly monitoring. The scheme penalises producers in proportion to input use in excess of a quota. A striking result is that if the scheme is designed in such a way that producers always comply with the quota, risk aversion is not relevant in determining the level of input use.

Evaluation processes of all types, including monitoring, review and impact assessment, offer unique opportunities for learning and provide useful feedback on what works and what doesn’t, and the reasons for success or failure. Involving staff members, partners and beneficiaries in the evaluation process allows them to reflect on their work, revisit their understanding of the project’s goals and activities, assess their effectiveness and take ownership of the evaluation findings. The knowledge created and the lessons learned through evaluation subsequently provide a basis for better project planning and implementation. This Brief outlines an evaluation approach that promotes learning and program improvement; it contrasts this approach with...

RE-ENGINEERING THE WELFARE SYSTEM - A STUDY OF ADMINISTRATIVE CHANGES TO THE FOOD STAMP PROGRAM: FINAL REPORT
Provedor de dados: 31
Autores: Bell,   Loren; Pachikara,   Susan; Williams,   Susan Schreiber; Gabor,   Vivian.
All States in a recent study undertook at least one "re-engineering" activity in their Food Stamp Programs (FSPs) as a result of the Personal Responsibility and Work Opportunity Reconciliation Act of 1996 (PRWORA). In addition, 35 States implemented changes in 3 or more re-engineering categories, while 24 States planned changes for fiscal year (FY) 2000 in 2 or more categories. PRWORA dramatically changed the systems that provide cash assistance and food stamps to low-income Americans. Along with mandatory changes in food stamp eligibility, States were given greater flexibility to administer their programs to meet their unique needs. While States had begun changing the way program services were delivered before passage of welfare reform legislation, PRWORA...

The Optimal Pricing of Pollution When Enforcement is Costly
Provedor de dados: 31
Autores: Stranlund,   John K.; Chavez,   Carlos A.; Villena,   Mauricio G.
We consider the pricing of a uniformly mixed pollutant when enforcement is costly with a model of optimal, possibly firm-specific, emissions taxes and their enforcement. We argue that optimality requires an enforcement strategy that induces full compliance by every firm. This holds whether or not regulators have complete information about firms’ abatement costs, the costs of monitoring them for compliance, or the costs of collecting penalties from noncompliant firms. Moreover, ignoring several unrealistic special cases, optimality requires discriminatory emissions taxes except when regulators are unable to observe firms’ abatement costs, the costs of monitoring individual firms, or any firm-specific characteristic that is known to be jointly distributed...

Optimal Management of Molds in Stored Corn
Provedor de dados: 31
Autores: Yigezu,   Yigezu A.; Alexander,   Corinne E.; Preckel,   Paul V.
Long term storage of corn is becoming more common due to the recent increase in the demand for corn by ethanol plants. Infection of maize kernels by toxigenic fungi remains a challenging storage problem despite decades of research. Experts in storage management propose the use of a combination of preventive and monitoring-based responsive strategies in response to mold risks. In this paper, a stochastic dynamic programming model is solved to determine the expected profitability and optimal combination, timing and intensity of the proposed mold management strategies using farmers’ existing infrastructure. The results show that even with relatively high monitoring costs, maintaining high quality grain using a monitoring based optimal mold management strategy...

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

DAIRY HERD MANAGEMENT PRACTICES FOCUSING ON PREWEANED HEIFERS
Provedor de dados: 31
Autores: Ott,   Stephen L.
The National Dairy Heifer Evaluation Project ( NDHEP ) was conducted by the National Animal Health Monitoring System (NAHMS ) from April 1991 through July 1992 with the assistance of 1,811 producers from 28 states. Producers included in the study each had herds of 30 or more milk cows, representing 78 percent of the milk cows in the U.S. The average total of cattle and calves on each operation was 169.4. The main breed on 94.9% of operations was Holstein. Slightly over 46 percent of operations stated reproductive problems as the cause of low milk production of cows culled from the herd. Newborn calves were separated from their mothers before nursing on 28.0 percent of operations and less than 12 hours after birth on 39.6 percent of operations. On 64.0...

ECONOMIC OPPORTUNITIES FOR DAIRY COW CULLING MANAGEMENT OPTIONS
Provedor de dados: 31
Autores: Ott,   Stephen L.
Due to a lack of national information about cull dairy cows, the USDA's National Animal Health Monitoring System (NAHMS) Dairy '96 Study investigated culling management practices. Operations included in the study represented 83.1 percent of U.S. milk cows. Most dairy cows were culled for reasons associated with their inability to profitably produce high-quality milk and calves; reasons for culling were not usually related to ill health or systemic disease. Results showed that almost all cull dairy cows in the US are intended for beef slaughter, as only about 4.4 percent were sent to other dairy operations. Nearly 77 percent of cows intended for beef slaughter were sent to markets, auctions, and sale barns, while 22 percent were sent straight to slaughter...

If services aren't delivered, people won't pay: the role of measurement problems and monitoring in Payments for Environmental Services
Provedor de dados: 31
Autores: Meijerink,   Gerdien W.
The idea of Payments for environmental services (PES) has an appealing simplicity, which may explain the success of the concept. However, successful projects are far limited though and two constraints have been identified in literature. The first is limited demand: too few service users are so confident about the mechanism that they are willing to pay. The second obstacle is poor knowledge on the institutional requirements entailing incentive and livelihood mechanisms which so far have received comparatively less attention. This paper focuses on both constraints by arguing that monitoring effectiveness and conditionality of PES schemes are crucial and that institutional arrangements for monitoring should be in place. By analysing in a systematic way what...

Monitoring regional economies in Australia: why and how
Provedor de dados: 31
Autores: Chapman,   Paul; Coelho,   Bruno.
Economic activity is inherently variable and monitoring it is a major challenge, especially in regional economies where resources are fewer and activity is more variable. Using a recent study of the Riverland region, the authors set out the information available, its limitations and means by which it may be extended. It is argued that monitoring must respond to specific needs and extend to information beyond the scope of the merely economic. It is not simply a matter of tracking commonly used economic variables but of understanding specific economic challenges and using that understanding to target economic and social information.

The Public Management of Risk: Separating Ex Ante and Ex Post Monitors
Provedor de dados: 31
Autores: Hiriart,   Yolande; Martimort,   David; Pouyet,   Jerome.
When a firm undertakes risky activities, the conflict between social and private incentives to implement safety care requires public intervention which can take the form of both monetary incentives but also ex ante or ex post monitoring, i.e., before or after an accident occurs. We delineate the optimal scope of monitoring depending on whether public monitors are benevolent or corruptible. We show that separating the ex ante and the ex post monitors increases the likelihood of ex post investigation, helps prevent capture and improves welfare.

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...

Trust in Authorities Monitoring the Distribution of Genetically Modified Foods: Dimensionality, Measurement Issues, and Determinants
Provedor de dados: 31
Autores: Bocker,   Andreas; Nocella,   Giuseppe.
Based on a combined internet and mail survey in Germany the independence of indicators of trust in public authorities from indicators of attitudes toward genetically modified food is tested. Despite evidence of a link between trust indicators on the one hand and evaluation of benefits and perceived likelihoods of risks, correlation with other factors is found to be moderate on average. But the trust indicators exhibit only a moderate relation with the respondents' preference for either sole public control or a cooperation of public and private bodies in the monitoring of GM food distribution. Instead, age and location in either the New or the Old Lander are found to be significantly related with such preferences.

The National Animal Health Monitoring Systems (NAHMS) Dairy +96 Study of dairy herds in 20 states examined herd management practices that varied between high-producing (top 25%) and low-producing (bottom 25%) U.S. dairy herds. Only 100% Holstein herds were included in the study. Within four size categories (30-99 cows, 100-199 cows, 200-499 cows, 500 or more cows) herds were ranked by milk production per cow. High-producing herds were more likely to use Dairy Herd Improvement Association records or an on-farm computer system than low-producing herds. High-producing herds were also more likely to feed a total mixed ration, use forage test results in balancing feed rations, use bovine somatotropin (bST) and/or systematic prostaglandins, and vaccinate against...

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

Outcome Mapping: A method for tracking behavioural changes in development programs
Provedor de dados: 31
Autores: Smutylo,   Terry.
Outcome mapping is a methodology for planning, monitoring and evaluating development initiatives that aim to bring about social change. The process of outcome mapping helps a project team or program to be specific about the actors it targets, the changes it expects to see and the strategies it employs. Results are measured in terms of the changes in behaviour, actions or relationships that can be influenced by the team or program. The methodology is comprised of several tools, which can be adapted to different contexts. It enhances team and program understanding of change processes, improves the efficiency of achieving results and promotes realistic and accountable reporting.

Do Consumers Want Public or Private Bodies to Monitor Animal Friendly Production and Marketing Schemes? And Does Trust Matter?
Provedor de dados: 31
Autores: Boecker,   Andreas; Nocella,   Giuseppe; Scarpa,   Riccardo.
Producing according to enhanced farm animal welfare (FAW) standards increases costs along the livestock value chain, especially for monitoring certified animal friendly products. In the choice between public or private bodies for carrying out and monitoring certification, consumer preferences and trust play a role. We explore this issue by applying logit analysis involving socio-economic and psychometric variables to survey data from Italy. Results identify marked consumer preferences for public bodies and trust in stakeholders a key determinant.

ABSTRACT: Helicoverpa armigera (Hübner) regularly requires quick deployment of control practices due to its potential of causing yield loss of processing tomatoes. The monitoring of H. armigera adults using stick traps lured with sex pheromone was correlated to egg densities, larvae, and percentage of damaged fruits, aiming to subsidize control decisions only using the number of males caught in the traps since surveying pest stages or damaged fruits is laborious and costly. Surveys were carried out on 11 tomato fields (ca. 80 to 120 hectares each) for processing during the 2015 and 2016 crop seasons. The survey was initiated at the flowering stage with traps set up along the field borders 100 m distant each. Evaluations of adult male capture in the traps...

Phenology, caudex growth and age estimation of Cyathea corcovadensis (Raddi) Domin (Cyatheaceae) in a subtropical forest in southern Brazil
Provedor de dados: 39
Autores: Neumann,Micheline Krüger; Schneider,Paulo Henrique; Schmitt,Jairo Lizandro.
Cyathea corcovadensis (Raddi) Domin occurs in northeastern, southeastern and southern Brazil, being widely distributed in the last. This was a three-year study, conducted from August 2008 to July 2011, in which we evaluated C. corcovadensis in a subtropical forest in southern Brazil. For the first year (August 2008 to July 2009), we monitored 30 plants on a monthly basis in order to analyze phenological events (vegetative and reproductive) and caudex growth. We also estimated the ages of the plants. Except in June and July of 2009, monthly leaf emergence and senescence were continuous and irregular, which prevented total leaf abscission, during that first year. Leaf emergence, senescence and fertility correlated with photoperiod, temperature and plant...

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

The use of biomarkers for assessing effects of pollutant stress on fish species from a tropical river in Southeastern Brazil
Provedor de dados: 3
Autores: Morado, Claudio Nona; Araújo, Francisco Gerson; Gomes, Iracema David.
Biomarkers are measurements within an organism that respond to environmental effects and are used as tools in bioassessment programs since they reflect physiological changes induced by exposure to pollutants. The hepatosomatic index (HSI) and the condition factor (CF) in three fish species Geophagus brasiliensis, Hypostomus affinis and Hypostomus auroguttatus were used to assess effects of pollutant stress in a tropical river during two seasons (dry and wet). Fish from the least disturbed sites had the lowest condition factor (CF) and the lowest HSI, whereas those from sites near pollutant discharges had the highest CF and HSI. Higher HSI and lower CF occurred during the dry season. It is suggested that species adapted to stressful conditions take...

Autores: BITTENCOURT-OLIVEIRA,MARIA DO CARMO; PICCIN-SANTOS,VIVIANE; MOURA,ARIADNE N.; ARAGÃO-TAVARES,NÍSIA K.C.; CORDEIRO-ARAÚJO,MICHELINE K.
Brazil has a history of blooms and contamination of freshwater systems by cyanobacterial toxins. The monitoring relevance of toxins from cyanobacteria in reservoirs for public supply is notorious given its high toxicity to mammals, included humans beings. The most recurrent toxins in Brazilian water bodies are microcystins (MC). However, the recent record of cylindrospermopsin (CYN) in northeastern Brazil, Pernambuco state, alerts us to the possibility that this could be escalating. This study reports occurrence of MC and CYN, quantified with ELISA, in 10 reservoirs, devoted to public drinking supply in northeastern Brazil. The composition and quantification of the cyanobacteria community associated with these water bodies is also presented. From 23...

Provedor de dados: 42
Autores: Wendland,Edson; Gomes,Luis H.; Troeger,Uwe.
The contribution of recharge to regional groundwater flow systems is essential information required to establish sustainable water resources management. The objective of this work was to determine the groundwater outflow in the Ribeirão da Onça Basin using a water balance model of the saturated soil zone. The basin is located in the outcrop region of the Guarani Aquifer System (GAS). The water balance method involved the determination of direct recharge values, groundwater storage variation and base flow. The direct recharge was determined by the water table fluctuation method (WTF). The base flow was calculated by the hydrograph separation method, which was generated by a rain-flow model supported by biweekly streamflow measurements in the control...

Mercury in the sea turtle Chelonia mydas (Linnaeus, 1958) from Ceará coast, NE Brazil
Provedor de dados: 42
Autores: Bezerra,Moisés F.; Lacerda,Luiz D.; Costa,Breno G.B.; Lima,Eduardo H.S.M.
Mercury concentrations in carapace fragments of the green turtle Chelonia mydas from the Ceará coast in NE Brazil are reported. Concentrations varied from &lt;0.34 to 856.6 ng.g -1 d.w., and were highest (average of 154.8 ng.g -1 d.w.) in juveniles (n = 22), whereas lowest concentrations (average of 2.5 ng.g -1 d.w.) were observed in adult/sub-adult animals (n = 3). There was a significant negative correlation between animal size and Hg concentration probably due to different diets between juveniles and sub-adults/adults. Carapace fragments, which are non-invasive, non-lethal substrates, may be of importance for monitoring purposes of these generally endangered species.

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...

Autores: Moreira,T. F.; Facury Filho,E. J.; Meneses,R. M.; Mendonça,F. L. M.; Lima,J. A. M.; Carvalho,A. U.
ABSTRACTWe used 31 crossbreed dairy cows to compare the energetic profile in summer and winter. Blood samples were taken weekly prepartum, at calving and on days 2, 5, 10, 15, 21 and 30 postpartum. All metabolic indicators analyzed were influenced by the physiological status. The glucose concentrations were higher during winter while the triglyceride concentrations and lactate dehydrogenase (LDH) were higher in the summer. The season influenced the concentrations of cholesterol, AST and GGT, showing a different pattern between summer and winter. Non-esterified fatty acids (NEFA) and beta-hidroxibutirate (BHB) were not influenced by the season. Cows that calved during winter had a greater body condition score (BCS) and lost more BCS until calving. During...

Mortality and adverse neurologic sequelae from HIV-associated cryptococcal meningitis (HIV-CM) remains high due to raised intracranial pressure (ICP) complications. Cerebrospinal fluid (CSF) high opening pressure occurs in more than 50% of HIV-CM patients. Repeated lumbar puncture with CSF drainage and external lumbar drainage might be required in the management of these patients. Usually, there is a high grade of uncertainty and the basis for clinical decisions regarding ICP hypertension tends to be from clinical findings (headache, nausea and vomiting), a low Glasgow coma scale score, and/or fundoscopic papilledema. Significant neurological decline can occur if elevated CSF pressures are inadequately managed. Various treatment strategies to address...
