Genetic structure in insular and mainland populations of house sparrows (Passer domesticus) and their hemosporidian parasites

Small and isolated populations usually exhibit low levels of genetic variability, and thus, they are expected to have a lower capacity to adapt to changes in environmental conditions, such as exposure to pathogens and parasites. Comparing the genetic variability of selectively neutral versus functional loci allows one to assess the evolutionary history of… (More)
