A Yale-led research team has developed a new approach to species conservation that prioritizes genetic and geographic rarity and applies it to all 9,993 known bird species.
“To date, conservation has emphasized the number of species, treating all species as equal,” said Walter Jetz, the Yale evolutionary biologist who is lead author of a paper published April 10 in Current Biology. “But not all species are equal in their genetic or geographic rarity. We provide a framework for how such species information could be used for prioritizing conservation.” (more…)
New Yale-led research suggests how and when Earth came to develop one of its most distinct features — rigid tectonic plates — and why Venus, Earth’s twin-like neighbor, never has.
“We think it all comes down to the behavior of tiny grains of minerals within rocks,” said Yale geophysicist David Bercovici, lead author of research published online April 6 in the journal Nature. (more…)
