14 Dogs (Canis lupus familiaris) were domesticated from gray wolves between 20-40kya in 15 Eurasia, yet details surrounding the process of domestication remain unclear. The vast array of 16 phenotypes exhibited by dogs mirror numerous other domesticated animal species, a 17 phenomenon known as the Domestication Syndrome. Here, we use signatures persisting in the 18 dog genome to identify genes ...

1. Environmental factors such as temperature, humidity and partial oxygen pressure can affect avian eggshell structure because gas exchange across the shell must allow sufficient water loss while preventing dehydration of the embryo. Studies of species with known chronology of colonization of novel environments provide a powerful insight into the relative importance of ecological factors shapin...

Despite the relatively recent divergence time between domestic dogs (Canis familiaris) and gray wolves (Canis lupus), the two species show remarkable behavioral differences. Since dogs and wolves are nearly identical at the level of DNA sequence, we hypothesize that the two species may differ in patterns of gene expression. We compare gene expression patterns in dogs, wolves and a close relativ...

The decline and extermination of an arctic wolf population in East Greenland between 1899 and 1939 were investigated through analysis of 40 years of archival data, which contained records of 252 sightings of wolves or their tracks. Prior to the start of exploitation by Europeans, this small, isolated wolf population probably consisted of about 38 wolves during an average year. Of 112 wolves sig...
