Within-island diversification in a passerine bird

Maëva Gabrielli, Benoit Nabholz, Thibault Leroy, Borja Milá & Christophe Thébaud
The presence of congeneric taxa on the same island suggests the possibility of in situ divergence, but can also result from multiple colonizations of previously diverged lineages. Here, using genome-wide data from a large population sample, we test the hypothesis that intra-island divergence explains the occurrence of four geographic forms meeting at hybrid zones in the Reunion grey white-eye (Zosterops borbonicus), a species complex endemic to the small volcanic island of Reunion. Using population genomic...

Stable resource polymorphism along the benthic littoral-pelagic axis in an invasive crayfish

Iris Lang, Charlotte Evangelista, Rebecca Marie Everts, Géraldine Loot & Julien Cucherousset
Although intraspecific variability is now widely recognized as affecting evolutionary and ecological processes, our knowledge on the importance of intraspecific variability within invasive species is still limited. This is despite the fact that quantifying the extent of within-population morphological divergences associated with the use of different trophic or spatial resources (i.e. resource polymorphism) can help to better predict their ecological impacts on recipient ecosystems. Here, we quantified the extent of resource polymorphism within populations of...
