@sagitaninta @Julien_JOSEPH We tested the hypothesis of a change in selection pressure due to a change in pathogens community between island and mainland. The problem is that island populations have lower Ne and, therefore, a reduce efficacy of selection. Result: #immune genes of island species show sign of reduced purifying selection but it is not statistically different from random genes. #IslandSyndrome #MolecularEvolution #Birds #Evolution

Our work just have been recommended in #PCIEvolBiol and, soon to be published in #PCIJournal : Barthe et al. Evolution of immune genes in island birds: reduction in population sizes can explain #islandsyndrome.
