Although we are currently experiencing worldwide biodiversity loss, local species richness does not always decline under anthropogenic pressure. This conservation paradox may also apply in protected areas but has yet received conclusive evidence marine ecosystems. Here, survey fish assemblages six Mediterranean no-take reserves and their adjacent fishing grounds using environmental DNA (eDNA) while controlling for conditions. We detect less than nearby fished areas. The paradoxical gradient...
The stress response is initially adaptive, operating to maintain homeostasis. However, chronic long-term exposure stressors may have detrimental effects. We proposed that be a major factor in demographic vole cycles, inducing decline high-density populations. monitored four populations of the fossorial water Arvicola scherman, which undergo pluriannual cycles Jura Mountains (France). Sampling was conducted during high densities and decline. measured fecal corticosterone metabolites (FCMs)...
Ecosystem services provided by oceans and seas support most human needs but are threatened activities. Despite existing maps illustrating impacts on marine ecosystems, information remains either large-scale rough insufficient for stakeholders (1 km² grid, lack of data along the coast) or fine-scale fragmentary heterogeneous in methodology. The objectives this study to map quantify main pressures exerted near-coast at a large spatial scale though fine relevant resolution managers (one pixel =...
The aesthetic value of landscapes contributes to human well-being. However, studies which have investigated the link between biodiversity and ecosystem services not taken into account. In this study we evaluated how aesthetics coralligenous reefs, a key marine in Mediterranean, is perceived by general public preferences are related facets (taxonomic, phylogenetic functional diversities). We performed both measures online-surveys perception on photographic quadrats sampled along French...
The seagrass Posidonia oceanica is the main habitat-forming species of coastal Mediterranean, providing millennial-scale ecosystem services including habitat provisioning, biodiversity maintenance, food security, protection, and carbon sequestration. Meadows this endemic represent largest storage among seagrasses around world, largely contributing to global blue stocks. Yet, slow growth temperate extreme projected temperature sea-level rise due climate change increase risk reduction loss...
Abstract Aim Coastal fishes have a fundamental role in marine ecosystem functioning and contributions to people, but face increasing threats due climate change, habitat degradation overexploitation. The extent which human pressures are impacting coastal fish biodiversity comparison with geographic environmental factors at large spatial scale is still under scrutiny. Here, we took advantage of DNA (eDNA) metabarcoding investigate the relationship between biodiversity, including taxonomic...
We investigated the factors mediating selection acting on two MHC class II genes (DQA and DRB) in water vole (Arvicola scherman) natural populations French Jura Mountains. Population genetics showed significant homogeneity allelic frequencies at DQA1 locus as opposed to neutral markers (nine microsatellites), indicating balancing this gene. Moreover, almost exhaustive screening for parasites, including gastrointestinal helminths, brain coccidia antibodies against viruses responsible...
Underwater photogrammetry has been increasingly used to study and monitor the three-dimensional characteristics of marine habitats, despite a lack knowledge on quality reliability reconstructions. More particularly, little attention paid exploring estimating relative contribution multiple acquisition parameters model resolution (distance between neighbour vertices), accuracy (closeness true positions / measures) precision (variability measures). On other hand, some studies expensive or...
Monitoring the biodiversity of key habitats and understanding drivers across spatial scales is essential for preserving ecosystem functions associated services. Coralligenous reefs are threatened marine hotspots that challenging to monitor. As fish sounds reflect in other habitats, we unveiled biogeography coralligenous reef north-western Mediterranean using data from 27 sites covering 2000 km 3 regions over a 3-year period. We assessed how acoustic related habitat parameters environmental...
Abstract To mitigate the ongoing threats to coastal ecosystems, and biodiversity erosion they are causing, marine‐protected areas (MPAs) have emerged as powerful widespread conservation tools. Strictly no‐take MPAs, also called marine reserves, undeniably promote fish biomass density, but it remains unclear how responds protection. Identifying which facets of respond protection is critical for management MPAs development relevant strategies towards achievement targets. We collected 99...
In a context of marine biodiversity erosion, the need to better understand effects overfishing stands out. New genetic techniques such as environmental DNA (eDNA) metabarcoding have emerged and allow detection wider range species compared conventional methods, but still fall short providing reliable abundance estimations subsequent ecological indicators. this paper, we propose combination quantitative polymerase chain reaction obtain quantity eDNA molecules per species. This method was used...
Cultural and recreational values of biodiversity are considered as important dimensions nature's contribution to people. Among these values, the aesthetics can be major importance appreciation beauty is one simplest forms human emotional response. Using an online survey, we disentangled effects different facets on aesthetic preferences coral reef fish assemblages that among most emblematic Earth. While found a positive saturating effect species' richness preference, net negative species...
Abstract Coastal areas offer a diversity of habitats providing refugia and nursery for fish, promoting their biodiversity associated contributions to people. Yet, natural coastlines are replaced by artificial infrastructures such as seaports the influence this artificialization on fish remains poorly known. Here, we assessed indicators using environmental DNA metabarcoding inside adjacent including no‐take marine reserves. We found that species assemblages within were primarily influenced...
The biodiversity crisis has spurred scientists to assess all facets of so that stakeholders can establish protection programs. However, species are perceived as beautiful receive more attention than less attractive species. This dynamic could have tremendous consequences on people's willingness preserve biodiversity. Coral reefs might be particularly affected by this issue they key ecosystems provide many services, such aesthetic and cultural benefits attracting millions tourists each year....
