Abstract Determining the species compositions of local assemblages is a prerequisite to understanding how anthropogenic disturbances affect biodiversity. However, biodiversity measurements often remain incomplete due limited efficiency sampling methods. This particularly true in freshwater tropical environments that host rich fish assemblages, for which assessments are uncertain and rely on destructive Developing an efficient nondestructive method assess freshwaters highly important. In this...
Abstract Environmental DNA (eDNA) metabarcoding is a promising tool to estimate aquatic biodiversity. It based on the capture of from water sample. The sampled volume, crucial aspect for efficient species detection, has been empirically variable (ranging few centiliters tens liters). This results in high variability sampling effort across studies, making comparisons difficult and raising uncertainties about completeness eDNA inventories. Our aim was determine (filtered volume) needed get...
Abstract Freshwater ecology templates were developed in temperate streams, but whether they also apply to tropical streams that harbour a higher biological diversity than their counterparts remains uncertain. This is particularly true for fish assemblages inhabiting small have been less studied larger, higher‐order lowland streams. Here, we disentangled the strength of spatial (longitudinal and environmental) drivers, scale‐specific (drainage basin, reach local scale) determinants species...
Abstract Aim Differences in dispersal limitation and environmental filtering have been proposed to explain differences diversity patterns between regions. Incorporating functional traits into studies of assembly rules allows the relative strengths such processes be distinguished. We test predictions that assemblages a similar environment under strong should differentiated taxonomically but not functionally, whereas more differentiate functionally.

Abstract Environmental DNA (eDNA) metabarcoding has recently gain much attention to assess aquatic environment biodiversity. A great variety of protocols have been developed collect, extract, and analyze eDNA, some which are continuously evolving optimized with technological improvements. Such shifts might deprecate the biological data produced earlier protocols, leading a loss knowledge. Here, we investigated robustness an eDNA method through comparison two biodiversity datasets generated...
Trees play a key role in the structure and function of many ecosystems worldwide. In Mediterranean Basin, forests cover approximately 22% total land area hosting large number endemics (46 species). Despite its particularities vulnerability, biodiversity trees is not well known at taxonomic, spatial, functional, genetic levels required for conservation applications. The WOODIV database fills this gap by providing reliable occurrences, four functional traits (plant height, seed mass, wood...
Environmental DNA [eDNA] metabarcoding has recently emerged as a non-destructive alternative to traditional sampling for characterising species assemblages. We here provide consistent dataset synthetising all eDNA sites in French Guiana date. Field collections have been initiated 2014 and continued until 2019. This is however work progress will be updated after each collecting campaign. also taxon by site matrix fishes presence / absence inferred from eDNA. Our aim allow transparent...
