Birds have for long been popular study objects in speciation research. Being easy to
observe in the field, they have traditionally been particularly important in studies of …

Details on the genetics of behavioral and quantitative phenotypes remain limited to a few
organisms. Such information is central to understanding both adaptation and speciation, as …

Studies on melanin-based color variation in a context of natural selection have provided a
wealth of information on the link between phenotypic and genetic variation. Here, we …

Genetic variation at the melanocortin-1 receptor (MC1R) gene is correlated with melanin
color variation in a few reported vertebrates. In Gyrfalcon (Falco rusticolus), plumage color …

The role of natural selection in shaping adaptive trait differentiation in natural populations
has long been recognized. Determining its molecular basis, however, remains a challenge …

Theoretical and empirical data suggest that genes located on sex chromosomes may play
an important role both for sexually selected traits and for traits involved in the build-up of …

Coloration is evolutionarily labile and so provides an excellent trait for examining the
repeatability of evolution. Here, we investigate the repeatability of the evolution of …

The zebra finch is the most common estrildid finch native to Australia and Southeast Asia.
The zebra finch has also been domesticated and is now a common pet and experimental …
