Past environmental change and seasonal migration shaped pronounced variability in the phylogenomic history of a morphologically cryptic bird radiation

Aim: Demographic inferences in combination with phylogenomic reconstructions provides a promising avenue to better understand the impact of past environmental changes on biogeographic patterns, yet we have only begun to exploit this potential. Here, based on genome resequencing data, we studied how regionally contrasting environmental conditions and variation in seasonal migration behaviour and dispersal ability influenced diversification of a cryptic bird radiation containing evolutionary lineages with extensive variation in distribution ranges across Eurasia.
Location: Eurasia
Taxon: Avian genus Riparia
Methods: We analyzed full genome data of 24 individuals, including all Eurasian Riparia taxa, using multi-pronged phylogenomic and demographic analyses. Hand-wing index (HWI) was used as proxy for migration and dispersal behaviour.
Results: Collared R. riparia and pale sand martin R. diluta showed genomic divergence at inter- and intraspecific level, aligning with described s..., We analyzed full genome data of 24 individuals including all Eurasian Riparia taxa using multi-pronged phylogenomic and demographic analyses.
