A Bocage Landscape Restricts the Gene Flow of Pest Vole Populations
Somoano, Aitor; Bastos-Silveira, Cristiane; Ventura, Jacint; Miñarro, Marcos; Heckel, GeraldThe population dynamics of most animal species inhabiting agro-ecosystems may be determined by landscape characteristics, with agricultural intensification and the reduction of natural habitats influencing dispersal and hence limiting gene flow. Increasing landscape complexity would thus benefit many endangered species by providing different ecological niches, but it could also lead to undesired effects in spec...
Ancient DNA reveals interstadials as a driver of common vole population dynamic...
Baca, Mateusz; Popović, Danijela; Lemanik, Anna; Bañuls‐Cardona, Sandra; Conard, Nicholas J.; Cuenca‐Bescós, Gloria; Desclaux, Emmanuel; Fewlass, HelenAim Many species experienced population turnover and local extinction during the Late Pleistocene. In the case of megafauna, it remains challenging to disentangle climate change and the activities of Palaeolithic hunter-gatherers as the main cause. In contrast, the impact of humans on rodent populations is likely to be negligible. This study investigated which climatic and/or environmental factors affect the po...
Variation and Selection in the Putative Sperm-Binding Region of ZP3 in Muroid R...
Duarte, Margarida Alexandra; Fernandes, C; Heckel, Gerald; da Luz Mathias, Maria; Bastos-Silveira, CristianeIn mammals, the zona pellucida glycoprotein 3 (ZP3) is considered a primary sperm receptor of the oocyte and is hypothesized to be involved in reproductive isolation. We investigated patterns of diversity and selection in the putative sperm-binding region (pSBR) of mouse ZP3 across Cricetidae and Murinae, two hyperdiverse taxonomic groups within muroid rodents. In murines, the pSBR is fairly conserved, in parti...
Deep mitochondrial introgression and hybridization among ecologically divergent...
Bastos-Silveira, Cristiane; Santos, Sara Maria; Monarca, Rita; Mathias, Maria da Luz; Heckel, GeraldThe completion of speciation is typically difficult to ascertain in rapidly diverging taxa but the amount of hybridization and gene flow in sympatry or parapatry contains important information about the level of reproductive isolation achieved. Here, we examined the progress in speciation between the Mediterranean (Microtus duodecimco- status) and the Lusitanian pine vole (M. lusitanicus), which are part of the m...
