AbstractThe usefulness of ecoregions and catchments (hydrologic units) as bases for classifying aquatic vertebrate assemblages in western Oregon was compared using samples collected by electrofishing ...

The cradle of vertebrate evolution was limited to a zone of shallow coastal waters, no more than 60 meters deep. In those waters, fish — the first vertebrates — appeared roughly 480 million years ago, ...

Competition between species played a major role in the rise and fall of hominins -- and produced a 'bizarre' evolutionary pattern for the Homo lineage -- according to a new study that revises the ...

Using the largest and most informative molecular phylogenetic dataset ever analysed, evolutionary biologists were able to construct a new phylogenetic tree of jawed vertebrates. This new tree resolves ...

This story appears in the October 2017 issue of National Geographic magazine. From scales to feathers to fur, vertebrates clothe themselves in a dazzling variety of textures and hues. But scientists ...

Prehensile tails and gliding have arisen only in certain taxonomic groups which could occur only on certain continents as a result of biogeographic history, e.g., no marsupials in Africa or flying ...

Behavioral lateralization, the preferential use of one side of the body and its corresponding brain hemisphere, is a pervasive aspect of vertebrate neurobiology. This phenomenon, which manifests in ...
