Genetic data obtained on population samples convey information about their evolutionary history. Inference methods can extract part of this but they require sophisticated statistical techniques that have been made available to the biologist community (through computer programs) only for simple and standard situations typically involving a small number samples. We propose here program (DIY ABC) inference based approximate Bayesian computation (ABC), in which scenarios be customized by user...
Recent studies of the routes worldwide introductions alien organisms suggest that many widespread invasions could have stemmed not from native range, but a particularly successful invasive population, which serves as source colonists for remote new territories. We call here this phenomenon bridgehead effect. Evaluating likelihood such scenario is heuristically challenging. solved problem by using approximate Bayesian computation methods to quantitatively compare complex invasion scenarios...
The invasion of Europe by the western corn rootworm, North America's most destructive pest, is ongoing and represents a serious threat to European agriculture. Because this pest was initially introduced in Central Europe, it believed that subsequent outbreaks Western originated from area. Using model-based Bayesian analyses genetic variability we demonstrate belief false: There have been at least three independent introductions America during past two decades. This result raises questions...
Abstract Microsatellites (or SSRs: simple sequence repeats) are among the most frequently used DNA markers in many areas of research. The use microsatellite is limited by difficulties involved their de novo isolation from species for which no genomic resources available. We describe here a high‐throughput method isolating based on coupling multiplex enrichment and next‐generation sequencing 454 GS‐FLX Titanium platforms. procedure was calibrated model ( Apis mellifera ) validated 13 other...
The early stages of invasion involve demographic bottlenecks that may result in lower genetic variation introduced populations as compared to source population/s. Low variability decrease the adaptive potential such their new environments. Previous population studies invasive species have reported varying levels losses comparisons and populations. However, intraspecific are required assess more thoroughly repeatability consequences colonization events. Descriptions for which multiple...
Abstract 1 The western corn rootworm Diabrotica virgifera LeConte is a major insect pest of field maize, Zea mays L. Larvae can cause substantial injury by feeding on maize roots. Larval may destroy individual roots or root nodes, and reduce plant growth, stability, yield. Costs associated with managing rootworms in continuous are annually one the largest expenditures for management United States Corn Belt. 2 Even though D. has been studied intensively over 50 years, there renewed interest...
Correct identification of the source population an invasive species is a prerequisite for testing hypotheses concerning factors responsible biological invasions. The native area may be large, poorly known and/or genetically structured. Because actual not have been sampled, studies based on molecular markers generate incorrect conclusions about origin introduced populations. In this study, we characterized genetic structure ladybird Harmonia axyridis in its using various statistics and...
The evolutionary trajectories associated with demographic, genetic and spatial disequilibrium have become an issue of growing interest in population biology. Invasive species provide unique opportunities to explore the impact recent range expansion on life-history traits, making it possible test for a arrangement dispersal abilities along expanding range, particular. We carried out controlled experiments laboratory conditions hypothesis increase capacity Harmonia axyridis, ladybird that has...
Abstract Comparison of demo‐genetic models using Approximate Bayesian Computation (ABC) is an active research field. Although large numbers populations and (i.e. scenarios) can be analysed with ABC molecular data obtained from various marker types, methodological computational issues arise when these become too large. Moreover, Robert et al. ( Proceedings the National Academy Sciences United States America , 2011, 108, 15112) have shown that conclusions drawn on model comparison cannot...
Inferences about introduction histories of invasive species remain challenging because the stochastic demographic processes involved. Approximate Bayesian computation (ABC) can help to overcome these problems, but such method requires a prior understanding population structure over study area, necessitating use alternative methods and an intense sampling design. In this study, we made inferences worldwide invasion history ladybird Harmonia axyridis by various genetics statistical methods,...
Abstract The Lepidopteran pest of tomato, Tuta absoluta , is native to South America and invasive in the Mediterranean basin. species' routes invasion were investigated. genetic variability samples collected America, Europe, Africa Middle East was analyzed using microsatellite markers infer precisely source populations test hypothesis a single versus multiple introductions into old world continents. This analysis provides strong evidence that origin invading unique close or Chile probably...
Abstract Genetic changes conferring adaptation to a new environment may induce fitness cost in the previous environment. Although this prediction has been verified laboratory conditions, few studies have tried document directly natural populations. Here, we evaluated pleiotropic effects of insecticide resistance on putative components mosquito Culex pipiens. Experiments using different larval densities were performed during summer two breeding sites. Two loci that possess alleles...
