Marine Biodiversity Exploitation and Conservation

Abstract Bioinformatic analysis of eDNA metabarcoding data is a crucial step toward rigorously assessing biodiversity. Many programs are now available for each the required analyses, but their relative abilities at providing fast and accurate species lists have seldom been evaluated. We used simulated mock communities real fish to evaluate performance 13 bioinformatic pipelines retrieve occurrence read abundance using 12S mt rRNA gene marker. four indices compare outputs program with...
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...
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...
Current approaches that compare spatial genetic structure of a given species and the dispersal its mobile phase can detect mismatch between both patterns mainly due to processes acting at different temporal scales. Genetic result from gene flow other evolutionary demographic over many generations, while predicted often represents solely one generation on single time‐step. In this study, we present graph approach landscape genetics extends connectivity networks with stepping‐stone model...
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...
Climate influences population genetic variation in marine species. Capturing these impacts remains challenging for fishes which disperse over large geographical scales spanning steep environmental gradients. It requires the extensive spatial sampling of individuals or populations, representative seascape heterogeneity, combined with a set highly informative molecular markers capable revealing climatic-associated variations. We explored how space, dispersal and environment shape genomic...
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...
Abstract Mesophotic marine ecosystems are characterized by lower light penetration supporting specialized fish fauna. Due to their depths (−30–−150 m), accessibility is challenging, and the structure of mesophotic assemblages generally less known than either shallow reefs or deep zones with soft bottoms which trawled. Environmental DNA metabarcoding from seawater filtered in situ could improve our ability monitor diversity ecosystems. Here, we developed tested a submersible standalone...
Dispersal is any movement of individuals from a source location (e.g. birth or breeding site) to another where establishment and reproduction may occur (Clobert et al. 2012). shapes species distribution plays key role in persistence under global change. It also has evolutionary gene flow, adaptation) biogeographic range shift, transmission disease) consequences (Álvarez-Noriega 2020). Specifically, long-distance dispersal that occurs beyond threshold distance not reached by most the...
ABSTRACT Aim The Mediterranean Sea is one of the most anthropized seas in world but also a marine biodiversity hotspot with many fish species under threat. main goal study to test whether on heavily fished and coast, less impacted Corsica Balearic Islands, can be considered as refugia for threatened elasmobranch fishes independently protection by reserves. Location French coast three north‐western islands: Mallorca Minorca from archipelago. Methods We performed 187 surveys using...
The eDNAqua-Plan project stands as a beacon of innovation in the biomonitoring marine and freshwater ecosystems, propelled by urgent need to integrate DNA-based approaches aquatic bioassessment monitoring frameworks. broad utilisation cutting-edge environmental DNA (eDNA) barcoding methodologies is dependent on complete, reliable, accessible reference sequence data (Rimet et al. 2021). Complete interoperable metadata crucial allow reuse (e)DNA analysis outputs, for broader uptake results end...
