Abstract Environmental DNA (eDNA) metabarcoding is a reliable method to assess taxonomic diversity, but the incompleteness of genetic reference databases prevents assignation many sequences given species. Functional diversity (FD) key biodiversity facet monitor, it requires identification all species within communities account for their trait values. So, ability eDNA‐based inventories estimate “true” level FD unknown. Here, using fish surveys in two representative temperate and tropical...
Abstract Environmental DNA has emerged as an efficient alternative to traditional sampling methods. A standard multispecies or a targeted single‐species approach can be used for analysing environmental samples. The costs, benefits, and drawbacks associated with these two approaches are quite different. Here, comparison between metabarcoding species assay using digital PCR (dPCR) threatened Harttiella occurring in French Guiana ( lucifer H . nsp. “Makwali”) was performed. Samples were...
Abstract To face the current downward trajectory of freshwater biodiversity loss, implementation effective monitoring programs is utmost importance. Environmental DNA offers unprecedented opportunities for this aim but several challenges still need to be addressed before implementing efficient species using eDNA. One them optimizing eDNA sampling scheme maximize detection probability. For instance, in flowing freshwaters, transport downstream from its source can impact probability, and blur...
Mosquitoes harbor a large diversity of eukaryotic viruses. Those viromes probably influence mosquito physiology and the transmission human pathogens. Nevertheless, their ecology remains largely unstudied. Here, we address two key questions in virome ecology. First, assessed species on taxonomic relative abundance. Contrary to most previous studies, potential effect habitat was explicitly included. Thousands individuals Culex poicilipes tritaeniorhynchus , vectors viral diseases, were...
The Neotropical region, hosts a quarter of all freshwater fish species, while providing important food resources for local human populations. management neotropical ecosystems is thus primary importance both biodiversity conservation and sustainability. Recent technological advances in the field genomics offer new tools managers practitioners to monitor entire assemblages using environmental DNA (eDNA) metabarcoding, or detect specific species populations targeted eDNA. availability...
