‘Extinction crisis even worse than realized’

“This new study shows that the extinction crisis is even worse than realized,” said Jonathan Losos, the William H. Danforth Distinguished University Professor and professor of biology in Arts & Sciences at Washington University in St. Louis and director of the Living Earth Collaborative.
Wolf spiders may turn to cannibalism in a warming Arctic

Wolf spiders may turn to cannibalism in a warming Arctic

A study by biologist Amanda Koltz in Arts & Sciences at Washington University in St. Louis suggests that as female wolf spiders become larger and produce more offspring, competition among them increases — triggering higher rates of cannibalism and reducing the number of young spiders that survive to adulthood.

Hot time in the city: Urban lizards evolve heat tolerance

Hot time in the city: Urban lizards evolve heat tolerance

Faced with a gritty landscape of metal fences, concrete walls and asphalt pavement, lizards that moved into cities in Puerto Rico rapidly and repeatedly evolved better tolerance for heat than their forest counterparts, according to new research from Washington University in St. Louis and the University of California, Los Angeles.
Birds of a feather better not together

Diversity plays a key role in maintaining the stability of plant and animal life in an area. But it’s difficult to scale up smaller experiments to understand how changes will impact larger ecosystems. A new study of North American birds from biologists in Arts & Sciences reveals the importance of both total numbers and variation in species identities.
