  Titre Global mismatch between species richness and vulnerability of reef fish assemblages Type Article scientifique
  Année (up) 2014 Publication Revue Abrégée Ecology Letters  
  Volume 17 Numéro 9 Pages 1101-1110  
  Mots-Clés Vulnerability; biodiversity; biodiversity loss; conservation; coral-reefs; extinction; fisheries; functional diversity; hotspots; macroecology; marine; patterns; protected areas; risk assessment; sensitivity  
  Résumé The impact of anthropogenic activity on ecosystems has highlighted the need to move beyond the biogeographical delineation of species richness patterns to understanding the vulnerability of species assemblages, including the functional components that are linked to the processes they support. We developed a decision theory framework to quantitatively assess the global taxonomic and functional vulnerability of fish assemblages on tropical reefs using a combination of sensitivity to species loss, exposure to threats and extent of protection. Fish assemblages with high taxonomic and functional sensitivity are often exposed to threats but are largely missed by the global network of marine protected areas. We found that areas of high species richness spatially mismatch areas of high taxonomic and functional vulnerability. Nevertheless, there is strong spatial match between taxonomic and functional vulnerabilities suggesting a potential win-win conservation-ecosystem service strategy if more protection is set in these locations.

  Titre Biogeography of freshwater fishes of the Balkan Peninsula Type Article scientifique
  Année (up) 2014 Publication Revue Abrégée Hydrobiologia  
  Volume 738 Numéro 1 Pages 205-220  
  Mots-Clés Balkan Peninsula; Beta diversity; Bioregionalisation; Conservation biogeography; Vulnerability; ancient lakes; biodiversity conservation; endemism; freshwater fish; global patterns; mitochondrial-dna sequences; north-america; phylogeography; species richness  
  Résumé Delineating biogeographical regions is a critical step towards the establishment and evaluation of conservation priorities. In the present study, we analysed the distribution patterns of the freshwater fish of an understudied European biodiversity hotspot, the Balkan Peninsula. Based on the most extensive available database of native freshwater fish species distributions, we performed a hierarchical clustering analysis to identify the major biogeographical regions of the Balkan Peninsula. We also highlighted the 'hottest hotspots' of freshwater fish diversity across the delimited biogeographical regions by describing the patterns of species richness, endemic and vulnerable species; indicator species were also determined. The bioregionalisation scheme consisted of eight groups of drainage basins that correspond to distinct regions of the Balkan Peninsula. Overall, the delineated biogeographical regions varied in terms of species richness, endemism, vulnerability (i.e. extinction threats) and indicator species composition. From a conservation perspective, this study emphasises the prioritisation of areas characterised by high levels of irreplaceability (endemism) and vulnerability (i.e. the Attikobeotia region, Ionian Sea and Prespa Lakes) and stresses the necessity of implementing a network of protected freshwater areas across the Balkan Peninsula.

  Titre Towards a framework for assessment and management of cumulative human impacts on marine food webs Type Article scientifique
  Année (up) 2015 Publication Revue Abrégée Conservation Biology  
  Volume 29 Numéro 4 Pages 1228-1234  
  Mots-Clés acciones de conservación; amenazas múltiples; conservation actions; ecosystem-based management; expert knowledge elicitation; manejo con base en los ecosistemas; multiple threats; obtención de conocimiento de expertos; pastos marinos; seagrass; vulnerabilidad; vulnerability  
  Résumé Effective ecosystem-based management requires understanding ecosystem responses to multiple human threats, rather than focusing on single threats. To understand ecosystem responses to anthropogenic threats holistically, it is necessary to know how threats affect different components within ecosystems and ultimately alter ecosystem functioning. We used a case study of a Mediterranean seagrass (Posidonia oceanica) food web and expert knowledge elicitation in an application of the initial steps of a framework for assessment of cumulative human impacts on food webs. We produced a conceptual seagrass food web model, determined the main trophic relationships, identified the main threats to the food web components, and assessed the components’ vulnerability to those threats. Some threats had high (e.g., coastal infrastructure) or low impacts (e.g., agricultural runoff) on all food web components, whereas others (e.g., introduced carnivores) had very different impacts on each component. Partitioning the ecosystem into its components enabled us to identify threats previously overlooked and to reevaluate the importance of threats commonly perceived as major. By incorporating this understanding of system vulnerability with data on changes in the state of each threat (e.g., decreasing domestic pollution and increasing fishing) into a food web model, managers may be better able to estimate and predict cumulative human impacts on ecosystems and to prioritize conservation actions.

  Titre Marine reserves lag behind wilderness in the conservation of key functional roles Type Article scientifique
  Année (up) 2016 Publication Revue Abrégée Nat. Commun.  
  Volume 7 Numéro Pages 12000  
  Mots-Clés biodiversity; coral-reef fishes; diversity indexes; ecosystem; new-caledonia; population-density; protected areas; species richness; visual-census; vulnerability  
  Résumé Although marine reserves represent one of the most effective management responses to human impacts, their capacity to sustain the same diversity of species, functional roles and biomass of reef fishes as wilderness areas remains questionable, in particular in regions with deep and long-lasting human footprints. Here we show that fish functional diversity and biomass of top predators are significantly higher on coral reefs located at more than 20 h travel time from the main market compared with even the oldest (38 years old), largest (17,500 ha) and most restrictive (no entry) marine reserve in New Caledonia (South-Western Pacific). We further demonstrate that wilderness areas support unique ecological values with no equivalency as one gets closer to humans, even in large and well-managed marine reserves. Wilderness areas may therefore serve as benchmarks for management effectiveness and act as the last refuges for the most vulnerable functional roles.
