Hitchhiking Parasites: Unstructured Populations of Bat Ectoparasites Reveal Host‐Driven DispersalNARA Subscribed
Understanding factors influencing the dynamics and distribution of parasites is essential to decipher the mechanism behind their spread and the identification of populations with elevated risks of infection. Bats—together with the diverse parasites they host and the influence of their social behaviour on parasitism—offer a suitable system. We investigated the extent to which differences in life history traits between parasite...
Geographical contrasts of Y‐chromosomal haplogroups from wild and domestic goats reveal ancient migrations and recent introgressionsNARA Subscribed
By their paternal transmission, Y‐chromosomal haplotypes are sensitive markers of population history and male‐mediated introgression. Previous studies identified biallelic single‐nucleotide variants in the SRY , ZFY and DDX3Y genes, which in domestic goats identified four major Y‐chromosomal haplotypes, Y1A, Y1B, Y2A and Y2B, with a marked geographical partitioning. Here, we extracted goat Y‐chromosomal variants from whole‐gen...
Genomic consequences of colonisation, migration and genetic drift in barn owl insular populations of the eastern MediterraneanNARA Subscribed
The study of insular populations was key in the development of evolutionary theory. The successful colonisation of an island depends on the geographic context, and specific characteristics of the organism and the island, but also on stochastic processes. As a result, apparently identical islands may harbour populations with contrasting histories. Here, we use whole genome sequences of 65 barn owls to investigate the patterns o...
Unexpected post‐glacial colonisation route explains the white colour of barn owls ( Tyto alba ) from the British IslesNARA Subscribed
The climate fluctuations of the Quaternary shaped the movement of species in and out of glacial refugia. In Europe, the majority of species followed one of the described traditional postglacial recolonization routes from the southern peninsulas towards the north. Like most organisms, barn owls are assumed to have colonized the British Isles by crossing over Doggerland, a land bridge that connected Britain to northern Europe. H...
Multiple introductions are key features for the establishment and persistence of introduced species. However, little is known about the contribution of genetic admixture to the invasive potential of populations. To address this issue, we studied the recent invasion of the Asian tiger mosquito ( Aedes albopictus ) in Europe. Combining genome‐wide single nucleotide polymorphisms and historical knowledge using an approximate Baye...
