The criteria used by previous authors to define colour aberrancies of snakes, particularly
albinism, are varied and terms were usually used ambiguously. The aim of this work was to …

Background The current distribution of genetic diversity is the result of a vast array of
microevolutionary processes, including short-term demographic and ecological mechanisms …

The corn snake (Pantherophis guttatus) is a new model species particularly appropriate for
investigating the processes generating colours in reptiles because numerous colour and …

Although there are more than 10,000 reptile species, and reptiles have historically
contributed to our understanding of biology, genetics research into class Reptilia has lagged …

Background Mediterranean islands host a disproportionately high level of biodiversity and
endemisms. Growing phylogeographic evidence on island endemics has unveiled …

Island organisms often evolve phenotypes divergent from their mainland counterparts,
providing a useful system for studying adaptation under differential selection. In the white …

Aims To characterize the genetic and morphological diversification of the endangered
Balearic lizard Podarcis lilfordi and to assess the relevance of this diversity, and how it is …

The existence of distinct traits in island versus mainland populations offers opportunities to
gain insights into how eco-evolutionary processes operate under natural conditions. We …

Identification of the role of the MC1R gene has provided major insights into variation in skin
pigmentation in several organisms, including humans, but the evolutionary genetics of this …

Two monophyletic sister species of wall lizards inhabit the two main groups of B alearic I
slands: P odarcis lilfordi from islets and small islands around M allorca and M enorca and P …
