Understanding the mechanisms underlying species formation and differentiation is a central
goal of evolutionary biology and a formidable challenge. This understanding can provide …

Oceanic islands are excellent systems for allowing biologists to test evolutionary hypotheses
due to their relative simplicity of habitats, naturally replicated study design and high levels of …

Migration is a ubiquitous life history trait with profound evolutionary and ecological
consequences. Recent developments in telemetry and genomics, when combined, can …

Half a century ago, MacArthur and Wilson proposed that the number of species on islands
tends toward a dynamic equilibrium diversity around which species richness fluctuates [1] …

A plethora of studies have offered crucial insights in the phylogeographic status of Western
Palearctic bird species. However, an overview integrating all this information and analyzing …

Aim Understanding the reasons why hosts lose, maintain or swap their parasite burden after
colonizing new areas has long intrigued island biogeographers. Using molecular markers …

The common chaffinch Fringilla coelebs is the extant avian species with the highest level of
differentiation across North Atlantic archipelagos. Such a degree of diversification has been …

Understanding the influence of intrinsic (genetic and morphological) and extrinsic
(geographical, environmental and social) factors on the performance and spatial …

The Setophaga petechia complex includes 43 subspecies distributed within the new world,
of which some are migratory and others are resident, with only two resident subspecies in …

We studied genetic diversity and differentiation in island and nearby continental populations
of a bird of prey, the common kestrel Falco tinnunculus. We sampled 11 islands in the …
