Borrowing a technique that biologists might use to study the evolution of plants or animals, the scientists plotted the “births” and “deaths” of every American-made car and truck model from 1896 to 2014.
Professor Blaire Van Valkenburgh, an internationally renown vertebrate biologist and paleontologist, has been appointed the inaugural Donald R. Dickey chair in Vertebrate Biology within the Department of Ecology and Evolutionary Biology. This endowed chair was created through a generous endowment from Donald R. Dickey, Jr. and Hisae Dickey. The endowment supports the professor who stewards the Donald R. Dickey Bird and Mammal Collection; it also supports the curation and maintenance of the collection.
The Dickey Bird and Mammal Collection is one of the world’s best collections of bird and mammal specimens from the American southwest and Central America. It houses nearly 64,000 specimens from North and Central America, and from islands in the Pacific. Also included in the collection are Donald R. Dickey’s rare photographs, books, and field notes. The invaluable collection of specimens are actively used, both for research and for undergraduate teaching. Professor Van Valkenburgh has curated the collection since 1986, and led the effort to bring the collection to its current optimal conditions in UCLA’s Hershey Hall.
UCLA biologists report in a new study that a species of foxes living on six of California’s Channel Islands have a surprising absence of genetic variation.
Domesticating dogs from gray wolves more than 15,000 years ago involved artificial selection and inbreeding, but the effects of these processes on dog genomes have been little-studied.
Over time, some species become more tolerant of humans’ presence, but the extent to which they do is largely driven by the type of environment in which the animals live and by the animal’s body size, according to a comprehensive new analysis.
UCLA researchers announced today the Bird Genoscape Project, which will create the first maps identifying the population-specific migration paths of several bird species and their sub-groups to determine where conservation is needed most to combat the effects of climate change.
