Journal ArticleDOI
The effect of RAD allele dropout on the estimation of genetic variation within and between populations
Mathieu Gautier,Karim Gharbi,Timothee Cezard,Julien Foucaud,Carole Kerdelhué,Pierre Pudlo,Pierre Pudlo,Jean-Marie Cornuet,Arnaud Estoup +8 more
TL;DR: It is found that ADO tends to overestimate genetic variation both within and between populations, and possible solutions to filter the most problematic cases of ADO using read coverage to detect markers with a large excess of null alleles are discussed.
Journal ArticleDOI
Clonal reproduction by males and females in the little fire ant.
Denis Fournier,Denis Fournier,Arnaud Estoup,Jérôme Orivel,Julien Foucaud,Hervé Jourdan,Julien Le Breton,Laurent Keller +7 more
TL;DR: Findings show that the haplodiploid sex-determination system provides grounds for the evolution of extraordinary genetic systems and new types of sexual conflict in the little fire ant Wasmannia auropunctata.
Journal ArticleDOI
Anthropogenically induced adaptation to invade (AIAI): contemporary adaptation to human-altered habitats within the native range can promote invasions
Ruth A. Hufbauer,Ruth A. Hufbauer,Benoit Facon,Virginie Ravigné,Julie Turgeon,Julie Turgeon,Julien Foucaud,Carol Eunmi Lee,Olivier Rey,Arnaud Estoup +9 more
TL;DR: It is proposed that recent adaptation within the native range, in particular adaptations to human‐altered habitat, could also contribute to the evolution of invasive populations.
Journal ArticleDOI
Estimation of population allele frequencies from next-generation sequencing data: pool-versus individual-based genotyping.
Mathieu Gautier,Julien Foucaud,Karim Gharbi,Timothee Cezard,Maxime Galan,Anne Loiseau,Marian Thomson,Pierre Pudlo,Pierre Pudlo,Carole Kerdelhué,Arnaud Estoup +10 more
TL;DR: Results are presented showing that, under many realistic experimental designs, NGS of DNA pools from diploid individuals allows to estimate the allele frequencies at single nucleotide polymorphisms (SNPs) with at least the same accuracy as individual‐based analyses, for considerably lower library construction and sequencing efforts.
Journal ArticleDOI
Deciphering the Routes of invasion of Drosophila suzukii by Means of ABC Random Forest.

Price,Julien Cattel,Xiao Chen,Maríndia Deprá,Pierre François Duyck,Christelle Guédot,Marc Kenis,Masahito T. Kimura,Gregory M. Loeb,Anne Loiseau,Isabel Martinez-Sañudo,Marta Pascual,Maxi Polihronakis Richmond,Peter W. Shearer,Nadia D. Singh,Koichiro Tamura,Anne Xuéreb,Jinping Zhang,Arnaud Estoup +26 more
TL;DR: It is found that Japan emerges as the most probable source of the earliest recorded invasion into Hawaii, and a new, more efficient, ABC method, ABC random forest (ABC-RF) is used, which out-performs ABC-LDA when using a comparable and more manageable number of simulated datasets.
