Models and indicators for assessing conservation and fisheries-related effects of marine protected areas
Provedor de dados: 5
Autores: Pelletier, Dominique; Claudet, Joachim; Ferraris, J; Benedetti Cecchi, L; Garcia Charton, J.
Two kinds of approaches have been used for assessing conservation and fisheries-related effects of marine protected areas (MPAs): (i) statistical modelling based on field data and (ii) mathematical modelling quantifying the consequences of MPAs on the dynamics of populations, communities, and fisheries. Statistical models provide a diagnostic on the impact of MPAs on the ecosystem and resources; they are also needed for devising and assessing sampling designs for monitoring programs. Dynamic models enable exploration of the consequences of MPA designs and other management policies. We briefly review how each of these approaches has been implemented up to now in the literature and identify potential indicators of MPA effects that can be obtained from each...

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...

Autores: Pelletier, Dominique; Garcia Charton, Jose; Ferraris, Jocelyne; David, Gilbert; Thebaud, Olivier; Letourneur, Yves; Claudet, Joachim; Amand, Marion; Kulbicki, Michel; Galzin, René.
The present paper aims at identifying and assessing indicators of the effects of Marine Protected Areas (MPAs) in coral reef regions, based on a bibliography review in ecology, economics and social sciences. First the various effects Studied within each of these domains and the variables used to measure them were censused. Potential ecological indicators were assessed through their link with the question used (here termed "relevance") and their "effectiveness" which encompasses the issues of precision, accuracy and statistical power. Relevance and effectiveness were respectively measured by the frequency of use of each indicator and the proportion of significant results in the reviewed articles. For social and economic effects, the approach was not...

The health of the ocean, central to human well-being, has now reached a critical point. Most fish stocks are overexploited, climate change and increased dissolved carbon dioxide are changing ocean chemistry and disrupting species throughout food webs, and the fundamental capacity of the ocean to regulate the climate has been altered. However, key technical, organizational, and conceptual scientific barriers have prevented the identification of policy levers for sustainability and transformative action. Here, we recommend key strategies to address these challenges, including (1) stronger integration of sciences and (2) ocean-observing systems, (3) improved science-policy interfaces, (4) new partnerships supported by (5) a new ocean-climate finance system,...

Coastal Ocean and Nearshore Observation: A French Case Study
Provedor de dados: 5
Autores: Cocquempot, Lucie; Delacourt, Christophe; Paillet, Jerome; Riou, Philippe; Aucan, Jérôme; Castelle, Bruno; Charria, Guillaume; Claudet, Joachim; Conan, Pascal; Coppola, Laurent; Hocdé, Régis; Planes, Serge; Raimbault, Patrick; Savoye, Nicolas; Testut, Laurent; Vuillemin, Renaud.
To understand and predict the physical, chemical, and biological processes at play in coastal and nearshore marine areas requires an integrated, interdisciplinary approach. The case study of the French structuration of coastal ocean and nearshore observing systems provides an original overview on a federative research infrastructure named ILICO. It is a notable example of national structuration and pan-institution efforts to investigate the forefront of knowledge on the processes at work within the critical coastal zone. ILICO comprises, in a pluridisciplinary approach, eight distributed network-systems of observation and data analysis that are accredited and financially supported by French research institutions and the French Ministry for Higher...

On the occasion of the 10th Indo-Pacific Fish Conference (http://ipfc10.criobe.pf/) to be held in Tahiti in October 2017, it seemed timely to update Randall's 1985 list of the fishes known from French Polynesia. Many studies focusing on fishes in this area have been published since 1985, but Randall's list remains the authoritative source. Herein we present an expanded species list of 1,301 fishes now known to occur in French Polynesia and we review the expeditions and information sources responsible for the over 60% increase in the number of known species since the publication of Randall's checklist in 1985. Our list of the fishes known from French Polynesia includes only those species with a reliably verifiable presence in these waters. In cases where...

Spatial management of inshore areas: Theory and practice
Provedor de dados: 5
Autores: Claudet, Joachim; Roussel, S; Pelletier, Dominique; Rey Valette, Hélène.
Coastal uses have deeply evolved these last decades and high anthropogenic pressures on coastal ecosystems have affected the sustainability of these areas with respect to the services and the resources they may provide. Traditional fisheries management has failed to avoid overexploitation of most coastal marine resources. Management measures based on an Integrated Coastal Zone Management (ICZM) are thus required. Spatial management covers various ranges of properties that may enhance usual regulatory means. If spatial considerations are explicitly integrated in fisheries management, the latter may contribute to zoning design in order to balance the economic, social and biological values of natural marine resources. While traditional fisheries management...

Autores: Thiault, Lauric; Mora, Camilo; Cinner, Joshua E.; Cheung, William W. L.; Graham, Nicholas A. J.; Januchowski-hartley, Fraser A.; Mouillot, David; Sumaila, U. Rashid; Claudet, Joachim.
Climate change can alter conditions that sustain food production and availability, with cascading consequences for food security and global economies. Here, we evaluate the vulnerability of societies to the simultaneous impacts of climate change on agriculture and marine fisheries at a global scale. Under a “business-as-usual” emission scenario, ~90% of the world’s population—most of whom live in the most sensitive and least developed countries—are projected to be exposed to losses of food production in both sectors, while less than 3% would live in regions experiencing simultaneous productivity gains by 2100. Under a strong mitigation scenario comparable to achieving the Paris Agreement, most countries—including the most vulnerable and many of the largest...

Without drastic efforts to reduce carbon emissions and mitigate globalized stressors, tropical coral reefs are in jeopardy. Strategic conservation and management requires identification of the environmental and socioeconomic factors driving the persistence of scleractinian coral assemblages—the foundation species of coral reef ecosystems. Here, we compiled coral abundance data from 2,584 Indo-Pacific reefs to evaluate the influence of 21 climate, social and environmental drivers on the ecology of reef coral assemblages. Higher abundances of framework-building corals were typically associated with: weaker thermal disturbances and longer intervals for potential recovery; slower human population growth; reduced access by human settlements and markets; and...

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

Fairly processing rare and common species in multivariate analysis of ecological series - Application to macrobenthic communities from Algiers harbour
Provedor de dados: 5
Autores: Mante, Claude; Claudet, Joachim; Rebzani Zahaf, C.
Systematic sampling of communities gives rise to large contingency tables summing up possible changes in the assemblages' structure. Such tables are generally analysed by multivariate statistical methods, which are ill-suited for simultaneously analysing rare and common species (Field et al., 1982). In order to separately process species belonging to either of these categories, we propose a statistical method to select common species in a sequence of ecological surveys. It is based on a precise definition of rarity, and depends on a rarity parameter.   In this work, this parameter will be optimised so that the sub-table of common species captures the essential features of the complete table as well as possible. In this way we analysed the spatio-temporal...

How does eutrophication impact bundles of ecosystem services in multiple coastal habitats using state-and-transition models
Provedor de dados: 5

One of the current major scientific challenges to sustain social-ecological systems is to improve our understanding of the spatial and temporal dynamics of the relationships between biodiversity, ecosystem functioning and ecosystem services. Here, we analyse the bundles of ecosystem services supplied by three coastal ecosystems (coastal lagoons, coral reefs and sandy beaches) along a gradient of eutrophication. Based on a state-and-transition model, we analyses the dynamic responses of ecological communities to environmental change and management actions. Although few exceptions are highlighted, increasing eutrophication in the three ecosystem types leads to a degradation of the ecosystem service bundles, particularly for nutrient and pathogen...

Aires marines protégées et récifs artificiels : méthodes d'évaluation, protocoles expérimentaux et indicateurs
Provedor de dados: 5
Autores: Claudet, Joachim.
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...

Assessing the effects of marine protected area (MPA) on a reef fish assemblage in a northwestern Mediterranean marine reserve: Identifying community-based indicators
Provedor de dados: 5
Autores: Claudet, Joachim; Pelletier, Dominique; Jouvenel, J.y; Bachet, F; Galzin, R.
Marine protected areas (MPAs) are increasingly envisaged as a tool to manage coastal ecosystems and fisheries. Assessment of their performance with respect to management objectives is therefore important. A number of WAS provided conservation benefits for fished species. Observed benefits do not apply to all species at all times, and responses to protection are also highly variable among fish taxa. Among the many empirical studies on marine reserves, only a few designs considered 'before and after data' and spatial variation. In this paper, we are interested in assessing the effect of a no-take reserve on the reef fish assemblage in a northwestern Mediterranean example. Data were obtained from a three-year survey using underwater visual censuses (UVC),...

AimBiological invasions are major contributors to global change and native biodiversity decline. However, they are overlooked in marine conservation plans. Here, we examine for the first time the extent to which marine conservation planning research has addressed (or ignored) biological invasions. Furthermore, we explore the change of spatial priorities in conservation plans when different approaches are used to incorporate the presence and impacts of invasive species. LocationGlobal analysis with a focus on the Mediterranean Sea region. MethodsWe conducted a systematic literature review consisting of three steps: (1) article selection using a search engine, (2) abstract screening and (3) review of pertinent articles, which were identified in the second...
