Giraffes, with their bizarre body plan, have always held a special place in the minds of evolutionary biologists and non-experts alike. In a new study whole-genome sequencing data was used to investigate the evolutionary processes occurring within giraffes. In particular, the authors were interested in establishing whether different populations of giraffes really have been isolated from each other for extended periods of time, which is normally a requirement before new species can arise.

The chance sighting of a dead snake beside a sandy track in remote Western Australia, and the investigation of its stomach contents, has led researchers to record the first known instance of a spotted mulga snake consuming a pygmy spiny-tailed skink, raising concerns for a similar-looking, endangered lizard species.

Early experiences in an animal's life can have a significant impact on its capacity to thrive, even years or decades later, and DNA methylation may help record their effects. In a study of 256 wild baboons, researchers found that resource limitation during early life was associated with many differences in DNA methylation, a small chemical mark on the DNA sequence that can affect gene activity.

Global change is altering the physiology of the hibernation and behavior of bats, according to a study carried out over a twenty year period. Given the milder winters we are having, bats are accumulating less fat reserves in autumn, they shorten their hibernation periods and they leave their winter shelter sooner. These changes could alter the migration pattern of bats and the phenology of their seasonal displacements.
