GENECLASS2 is a software that computes various genetic assignment criteria to assign or exclude reference populations as the origin of diploid haploid individuals, well groups on basis multilocus genotype data. In addition traditional aims, program allows specific task first-generation migrant detection. It includes several Monte Carlo resampling algorithms compute for each individual its probability belonging population be resident (i.e., not migrant) in where it was sampled. A...
Abstract A new method for assigning individuals of unknown origin to populations, based on the genetic distance between and was compared two existing methods likelihood multilocus genotypes. The distribution assignment criterion (genetic or genotype likelihood) a given population used define probability that an individual belongs population. Using this definition, it becomes possible exclude as individual, useful extension currently available methods. simulated data coalescent process,...
Understanding the role of seascape in shaping genetic and demographic population structure is highly challenging for marine pelagic species such as cetaceans which there generally little evidence what could effectively restrict their dispersal. In present work, we applied a combination recent individual-based landscape approaches to investigate mobile extensive range cetacean, harbour porpoise eastern North Atlantic, with regards oceanographic characteristics that constrain its Analyses 10...
An understanding of the role factors intrinsic to a species' life history in structuring contemporary genetic variation is fundamental, but understudied, aspect evolutionary biology. Here, we assessed influence propensity outbreak shaping worldwide Locusta migratoria, cosmopolitan pest well known for its expression density-dependent phase polyphenism. We scored 14 microsatellites nine subspecies from 25 populations distributed over most range regions that vary historical frequency and extent...
Plant diversification using cover crops may promote natural regulation of agricultural pests by supporting alternative prey that enable the increase arthropod predator densities. However, changes in specific composition diet induced cropping are poorly understood. Here, we hypothesized crop can significantly alter predators agroecosystems. The Brachiaria decumbens is increasingly used banana plantations to control weeds and improve physical soil properties. In this paper, a DNA metabarcoding...
Black rats are major invasive vertebrate pests with severe ecological, economic and health impacts. Remarkably, their evolutionary history has received little attention, there is no firm agreement on how many species should be recognized within the black rat complex. This complex native to India Southeast Asia. According current taxonomic classification, three taxa living in sympatry several parts of Thailand, Cambodia Lao People's Democratic Republic, where this study was conducted: two...
Abstract The worldwide intensification of human‐associated exchanges favours the multiplication biological invasions. Among mammals, rodent species, including house mouse M us musculus , are identified as major invaders with profound impacts on native biodiversity, human health and activities. Though contemporary invasions described several islands, there few data describing ongoing in continental areas. We first outline known picture distribution A frica. then describe range expansion S...
Many pest species exhibit huge fluctuations in population abundance. Understanding their large-scale and long-term dynamics is necessary to develop effective control management strategies. Occupancy models represent a promising approach unravel interactions between environmental factors spatiotemporal of outbreaking populations. Here, we investigated the Australian plague locust, Chortoicetes terminifera, using density data collected 1988 2010 by Plague Locust Commission over more than 3...
Contact zones between ecotypes are windows for understanding how species may react to climate changes. Here, we analysed the fine-scale genetic and morphological variation in harbour porpoises ( Phocoena phocoena ) around UK by genotyping 591 stranded animals at nine microsatellite loci. The data were integrated with a prior study map high resolution contact zone two previously identified meeting northern Bay of Biscay. Clustering spatial analyses revealed that derived from pools...
Abstract During the most recent decade, environmental DNA metabarcoding approaches have been both developed and improved to minimize biological technical biases in these protocols. However, challenges remain, notably those relating primer design. In current study, we comprehensively assessed performance of ten COI two 16S pairs for eDNA metabarcoding, including novel previously published primers. We used a combined approach silico, vivo‐mock community (33 arthropod taxa from 16 orders),...
In a context of unprecedented insect decline, it is critical to have reliable monitoring tools measure species diversity and their dynamic at large‐scales. High‐throughput DNA‐based identification methods, particularly metabarcoding, were proposed as an effective way reach this aim. However, these methods are subject multiple technical limitations, resulting in unavoidable false‐positive false‐negative detection. Moreover, metabarcoding does not allow estimation abundance given sample, which...
Abstract Aim To investigate the phylogeographical structure of Guinea multimammate mouse, Mastomys erythroleucus (Temminck, 1853), a widespread murid rodent in sub‐Saharan (Sahel and Sudan) savannas, for better understanding impacts geographical historical factors on evolutionary history this species, context growing database studies African savanna mammal species. Location Sahel Sudan Africa. Methods We sequenced whole cytochrome b gene 211 individuals from 59 localities distributed Senegal...
Abstract Travelling waves ( TW ) are among the most striking ecological phenomena emerging in oscillating populations. Despite much theory, understanding how real‐world arise remains a challenge for ecology. Herein, we analyse 16‐year time series of cyclic vole populations collected at 314 localities covering 2500 km² France. We found evidence linear front spreading speed 7.4 km year −1 along north‐west/south‐east direction and radiating away from major landscape discontinuity as predicted...
Abstract Dietary plasticity can be a determining factor allowing species to cope with environmental changes. Consequently, it is an important issue consider in conservation biology. Despite this, remains rarely addressed the literature, potentially due methodologies which were until recently rather limited. The advent of molecular approaches now makes possible get precise picture diet and its plasticity, even for endangered elusive species. Here, we focused on greater horseshoe bat (...
Abstract Studies focusing on geographical genetic patterns of commensal species and human history complement each other provide proxies to trace common colonization events. On Madagascar, the unintentional introduction spread R attus rattus by people may have left a living clue history. In this study, we addressed question characterizing structure natural populations . using both microsatellites mitochondrial sequences, an extensive sampling across island. Such data sets were analysed...
Abstract DNA metabarcoding of faecal samples is being successfully used to study the foraging niche species. We assessed ability two benchtop high-throughput sequencing (HTS) platforms, identify a large taxonomic array food items from domestic cats Felis silvestris catus , including prey and human-related taxa (pet leftovers leaving undetectable solid remains in faeces). Scats captive feeding trial ( n = 41) free-ranging individuals 326) were collected analysed using cyt b mini-barcode...
Changes in host-parasite ecological interactions during biological invasion events may affect both the outcome of invasions and dynamics exotic and/or endemic infections. We tested these hypotheses, by investigating ongoing house mouse (Mus musculus domesticus) black rat (Rattus rattus) Senegal (West Africa). used a 16S gene rRNA amplicon sequencing approach to study potentially zoonotic bacterial communities invasive native rodents sampled along two well-defined independent routes. found...
Summary Visualisation of spatial networks based on pairwise metrics such as (dis)similarity coefficients provides direct information organisation biological systems. However, for large networks, graphical representations are often unreadable nodes (samples), and edges (links between samples) strongly overlap. We present a new method, MAPI, allowing translation from to variation surfaces. MAPI relies (i) network in which samples linked by ellipses (ii) grid hexagonal cells encompassing the...
Species distribution models (SDM) have often been used to predict the potential ranges of introduced species and prioritize management strategies. However, this approach assumes equilibrium between occurrences environmental gradients, an assumption which is violated during invasion process, where many suitable sites are empty because has not yet reached them. Here we considered invasive ladybird Harmonia axyridis as a case study show benefits using dynamic colonization–extinction model that...
Through international trades, Europe, Africa and South America share a long history of exchanges, potentially pathogens. We used the worldwide parasite Toxoplasma gondii to test hypothesis historical influence on pathogen genetic diversity in Benin, West African country with longstanding sea trade history. In Africa, T . spatial structure is still non-uniformly studied very few articles have reported strain fauna clinical forms human toxoplasmosis so far, even diaspora. Sera from 758...
Human population migrations, as well long-distance trade activities, have been responsible for the spread of many invasive organisms. The black rat, Rattus rattus, has colonized most world following ship-mediated trade. Owing to its tight association with human infrastructures, this species able survive in unfavourable environments, such Sahelian Africa. In work, we combined interview-based and genetic surveys investigate processes underlying ongoing invasion south-western Niger by rats,...
