Migratory behaviour affects the size of brains in birds
Researchers at Centre for Ecological Research and Forestry Applications (CREAF, a UAB-affiliated centre) shed new light on the evolution of brain size in birds. Scientists have known for some time that migratory birds have smaller brains than their resident...

Evolution could be predictable
Clines are trends in a morphological variation due to environmental influences. In Drosophila flies, one of the known clines is the size of their wings depending on latitude. The study of the American populations of Drosophila suboscura, carried out by a group of UAB geneticists, has led to a...
