Abstract Background Estuaries are complex ecosystems linking river and marine environments, where microorganisms play a key role in maintaining ecosystem functions. In the present study, we investigated monthly 8 sites at two depth layers over one-year period bacterial eukaryotic community dynamics along Seine macrotidal estuary (Normandy, France). To date, taxonomy of microbial diversity this anthropized remains elusive drivers structure still unknown. Results The metabarcoding analysis 147...
This article documents the addition of 396 microsatellite marker loci to Molecular Ecology Resources Database. Loci were developed for following species: Anthocidaris crassispina, Aphis glycines, Argyrosomus regius, Astrocaryum sciophilum, Dasypus novemcinctus, Delomys sublineatus, Dermatemys mawii, Fundulus heteroclitus, Homalaspis plana, Jumellea rossii, Khaya senegalensis, Mugil cephalus, Neoceratitis cyanescens, Phalacrocorax aristotelis, Phytophthora infestans, Piper cordulatum,...
Abstract Because they house large biodiversity collections and are also research centres with sequencing facilities, natural history museums well placed to develop DNA barcoding best practices. The main difficulty is generally the vouchering system: it must ensure that all data produced remain attached corresponding specimen, from field publication in articles online databases. Museum National d’Histoire Naturelle Paris one of leading laboratories Marine Barcode Life (MarBOL) project, which...
The primary purpose of DNA-barcoding projects is to generate an efficient expertise and identification tool. This important challenge the taxonomy 21st century, as demand increases expert capacity does not. However, identifying specimens using DNA-barcodes requires a preliminary analysis relate molecular clusters available scientific names. Through case study genus Eumunida (Decapoda : Eumunididae), we illustrate how naming molecule-based units, thus providing accurate DNA-based tool,...
The European bison (Bison bonasus), now found in Europe and the Caucasus, has been proposed to originate either from extinct steppe/extant American lineage or Bison schoetensacki lineage. remains are documented Eurasian Middle Pleistocene sites, but their presence Upper sites questioned. Despite extensive genetic studies carried out on steppe bison, no fossil record morphologically identified as analyzed up now. In this paper, we a 36,000-year-old schoetensaki bone sample Siréjol cave...
Inselbergs are isolated granitic rock outcrops that provide distinctive ecological conditions. In northern South America they rise above the surrounding rainforest. Among inselberg specialists, Pitcairnia geyskesii (Bromeliaceae) is restricted to these habitats in French Guiana. We studied populations from 12 inselbergs using 7 microsatellite loci give a “reverse image” of reduction‐expansion rainforest context refuge hypothesis. Our analyses showed fragmented with dispersal occurring only...
The seamounts chain offers a set of fragmented habitats in which species with poor dispersive ability may undergo divergence allopatry. Such scenario explain the endemism often described on seamounts. In gastropods, it is possible to infer mode development from morphology its larval shell. Accordingly, we examine population genetics several caenogastropods Norfolk and Lord Howe (south-west Pacific) contrasting modes development. A prerequisite our study was clarify taxonomic framework....
Rafts of drifting pelagic Sargassum that are circulating across the Atlantic Ocean complex ecosystems composed a large number associated species. Upon massive stranding, they lead to various socio-environmental issues including inflow contaminants and human health concerns. In this study, we used metabarcoding approaches examine differences in both eukaryotic- prokaryotic-associated communities from present two islands Lesser Antilles, namely Guadeloupe Martinique. We detected significant...
Termites have co-evolved with a complex gut microbiota consisting mostly of exclusive resident taxa, but key forces sustaining this partnership are still poorly understood. The potential for primary reproductives to vertically transmit their (mycobiome and bacteriome) offspring was investigated using colony foundations from field-derived swarming alates Macrotermes subhyalinus . Metabarcoding based on the fungal internal transcribed spacer (ITS) region bacterial 16S rRNA gene used...
Even though their occurrence was reported a long time ago, sunken wood ecosystems at the deep-sea floor have only recently received specific attention. Accumulations of fragments in deep sea create niches for diverse fauna, but significance itself as food source remains to be evaluated. Pectinodonta sp. is patellogastropod that exclusively occurs on woody substrates, where individuals excavate depressions, and thus potential candidate wood-eating lifestyle. Several approaches were used...
Abstract In small populations of monogamous species sex ratio bias and sex-skewed demographic traits could lead to higher extinction probabilities than in other mating systems. Therefore a knowledge ratio, mortality movement would be useful determine the optimal strategy for sampling founders prior reintroduction. We used molecular sexing wild-hatched cohorts two colonies (one native one reintroduced) four released groups griffon vultures Gyps fulvus France. was not different from...
The Hermann's tortoise (Testudo hermanni) is an endangered land distributed in disjoint populations across Mediterranean Europe. We investigated its genetic variation by typing 1 mitochondrial locus and 9 nuclear microsatellites approximately 300 individuals from 22 localities. Our goal was to understand the relative impact of natural human-mediated processes shaping structure identify priorities for conservation this species. found that 1) all geographic areas are highly differentiated,...
Abstract Freshwater species on tropical islands face localized extinction and the loss of genetic diversity. Their habitats can be ephemeral due to variability in freshwater run‐off erosion. Even worse, anthropogenic effects these ecosystems are intense. Most amphidromous or catadromous (i.e. their life cycle includes a marine larval phase), which buffers them against many effects. A long pelagic duration ( PLD ) was thought critical ensure colonization persistence islands, but recent...
Abstract Pitcairnia geyskesii is a saxicolous bromeliad endemic to the granitic inselbergs of French Guiana and Surinam. Seven polymorphic microsatellite markers were characterized investigate polymorphism among individuals sampled on five in Guiana. The total number alleles per locus varied from four 14. Mean observed heterozygosities at each ranged 0.114 0.629. This set microsatellites offers an efficient tool for more detailed investigations genetic structure fragmented populations living...
• Premise of the study: Microsatellite loci were developed for understudied root crop yam bean ( Pachyrhizus spp.) to investigate intraspecific diversity and interspecific relationships within genus . Methods Results: Seventeen nuclear simple sequence repeat (SSR) markers with perfect di‐ trinucleotide repeats from 454 pyrosequencing SSR‐enriched genomic libraries. Loci characterized in P. ahipa wild cultivated populations four closely related species. All successfully cross‐amplified showed...
