Abstract Molecular markers produced by next‐generation sequencing ( NGS ) technologies are revolutionizing genetic research. However, the costs of analysing large numbers individual genomes remain prohibitive for most population genetics studies. Here, we present results based on mathematical derivations showing that, under many realistic experimental designs, DNA pools from diploid individuals allows to estimate allele frequencies at single nucleotide polymorphisms SNP s) with least same...
Summary Microsatellites are currently considered the most useful genetic markers with wide applications in genomics, quantitative and population genetics. We present here structure of core sequence 552 microsatellites, together sequences primers length sequenced allele. These microsatellites were isolated from several libraries constructed either fractions total genomic DNA or clones a bacterial artificial chromosome (BAC) library. All loci polymorphic honeybee. Many them also successfully...
Several recent public health crises have shown that the surveillance of zoonotic agents in wildlife is important to prevent pandemic risks. High-throughput sequencing (HTS) technologies are potentially useful for this surveillance, but rigorous experimental processes required use these effective tools such epidemiological contexts. In particular, HTS introduces biases into raw data set might lead incorrect interpretations. We describe here a procedure cleaning before estimating reliable...
Deciphering invasion routes from molecular data is crucial to understanding biological invasions, including identifying bottlenecks in population size and admixture among distinct populations. Here, we unravel the of invasive pest Drosophila suzukii using a multi-locus microsatellite dataset (25 loci on 23 worldwide sampling locations). To do this, use approximate Bayesian computation (ABC), which has improved reconstruction routes, but can be computationally expensive. We our study...
Many animal species comprise discrete phenotypic forms. A common example in natural populations of insects is the occurrence different color patterns, which has motivated a rich body ecological and genetic research [1-6]. The dark, i.e., melanic, forms displaying patterns found across multiple taxa, but underlying genomic basis remains poorly characterized. In numerous ladybird (Coccinellidae), spatial arrangement black red patches on adult elytra varies wildly within species, forming...
Abstract Evidence is accumulating that evolutionary changes are not only common during biological invasions but may also contribute directly to invasion success. The genomic basis of such still largely unexplored. Yet, understanding the response help predict conditions under which invasiveness can be enhanced or suppressed. Here, we characterized genome spotted wing drosophila Drosophila suzukii worldwide this pest insect species, by conducting a genome-wide association study identify genes...
Abstract Biological invasions are generally thought to occur after human aided migration a new range. However, activities prior may also play role. We studied here the evolutionary genetics of introduced populations invasive ant Wasmannia auropunctata at worldwide scale. Using microsatellite markers, we reconstructed main routes introduction species. found three introduction, each them strongly associated history and trading routes. demonstrate overwhelming occurrence male female clonality...
Abstract Evolution may improve the invasiveness of populations, but it often remains unclear whether key adaptation events occur after introduction into recipient habitat (i.e. post‐introduction scenario), or before within native range prior‐adaptation scenario) at a primary site invasion bridgehead scenario). We used multidisciplinary approach to determine which these three scenarios underlies tropical ant Wasmannia auropunctata in Mediterranean region Israel). Species distribution models (...
Abstract A better understanding of the factors affecting host plant use by spotted-wing drosophila (Drosophila suzukii) could aid in development efficient management tools and practices to control this pest. Here, proxies both preference (maternal oviposition behavior) performance (adult emergence) were evaluated for 12 different fruits form purees. The effect chemical composition on traits was then estimated. We synthesized literature interpret our findings light previous studies that...
Abstract Nine microsatellite markers were characterized in the fungus Botrytis cinerea . Genomic DNA sequences from partial sequencing of 12 000 bacterial artificial chromosome (BAC) clones, screened by BLAST for various motives, and primer pairs designed. Cross‐amplification polymorphism assessed on 49 isolates B. two related species, collected natural populations several plants locations.
Abstract A linkage map for the honeybee (Apis mellifera) was constructed mainly from progeny of two hybrid queens (A. m. ligustica × A. mellifera). total 541 loci were mapped; 474 microsatellite loci; a few additional bands produced during PCRs, one rDNA (using ITS), MDH locus, and three sex-linked markers (Q FB RAPD band). Twenty-four groups estimated which 5 minute (between 7.1 22.8 cM) 19 major (>76.5 cM). The number exceeded by chromosomes complement (n = 16). sum lengths all...
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...
So far, only a few studies have explicitly investigated the consequences of admixture for adaptative potential invasive populations. We addressed this question in ladybird Harmonia axyridis. After decades use as biological control agent against aphids Europe and North America, H. axyridis recently became four continents has now spread widely Europe. Despite invasion, flightless strain is still sold However, crosses between individuals yield able to fly, phenotype caused by single recessive...
The potential effect of population outbreaks on within and between genetic variation populations in pest species has rarely been assessed. In this study, we compare patterns different sets historically frequently outbreaking an agricultural major importance, the migratory locust, Locusta migratoria. We analyse 24 at 14 microsatellites Western Europe, where only ancient low-intensity have reported (non-outbreaking populations), Madagascar Northern China, frequent intense outbreak events...
Leptospirosis essentially affects human following contact with rodent urine-contaminated water. As such, it was mainly found associated rice culture, recreational activities and flooding. This is also the reason why has been investigated in temperate as well warm humid regions, while arid zones have only very occasionally monitored for this disease. In particular, data West African countries are extremely scarce. Here, we took advantage of an extensive survey urban rodents Niamey, Niger,...
Abstract The invasive ant species Wasmannia auropunctata displays both ecologically dominant and non‐dominant populations within its native range. Three factors could theoretically explain the ecological dominance of some W. : (i) clonal reproductive system, through demographic and/or adaptive advantages; (ii) unicolonial social organization, lower intraspecific efficient interspecific competition; (iii) human disturbance range, modification biotic abiotic environmental conditions. We used...
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...
Using the same set of microsatellite markers, we compared population genetic structure two Mastomys species, one being exclusively commensal in southeastern Senegal, and other continuously distributed outside villages this region. Both species were sampled landscape context at spatial scale. According to expectations based on degree habitat patchiness (which is higher for populations rural area), diversity was lower differentiation natalensis than wild erythroleucus. Contrasting estimates...
The little fire ant, Wasmannia auropunctata, displays a peculiar breeding system polymorphism. Classical haplo-diploid sexual reproduction between reproductive individuals occurs in some populations, whereas, others, queens and males reproduce clonally. Workers are produced sexually sterile both clonal populations. evolutionary fate of the lineages depends strongly on underlying mechanisms allowing to transmit their genomes subsequent generations. We used several queen-offspring data sets...
