摘要: Spatial variation in the pattern of natural selection can promote local adaptation and genetic differentiation between populations. Because heritable melanin-based ornaments signal resistance to environmentally mediated elevation glucocorticoids, oxidative stress parasites, populations may vary mean degree melanic coloration if on these phenotypic aspects varies geographically. Within a population Swiss barn owls (Tyto alba), size eumelanic spots is positively associated with survival, immunity stress, but it yet unknown whether Tyto species that face stressful environments evolved towards darker plumage. regimes along environmental gradients, we examined traits clinally are expressed larger extent tropics where parasites more abundant than temperate zones. To this end, considered 39 owl distributed worldwide. Barn living displayed those found This was, however, verified northern hemisphere only. Parasites being particularly tropics, they evolution ornaments.
