The space between us

The space between us

Arts & Sciences biologists from the lab of Jonathan Myers determined that tree beta diversity — a measure of site-to-site variation in the composition of species present within a given area — matters more for the ecosystem than other components of biodiversity at larger scales.
When more complex is simpler

When more complex is simpler

A new modeling framework proposed by physicist Mikhail Tikhonov in Arts & Sciences demonstrates how a more complex microbial ecosystem can be more coarse-grainable, making it potentially easier for scientists to understand, than one with only a few microbes interacting.
Nonlethal parasites reduce how much their wild hosts eat, leading to ecosystem effects

Nonlethal parasites reduce how much their wild hosts eat, leading to ecosystem effects

Research from the Living Earth Collaborative highlights the cascading consequences of common parasitic infections. Although many of these infections are not lethal, they can still impact health or animal behavior, leading hosts to eat less vegetation. The study led by biologist Amanda Koltz in Arts & Sciences is published in the Proceedings of the National Academy of Sciences.

Canid conservation program launched

Canid conservation program launched

Washington University in St. Louis and the Living Earth Collaborative are part of a new Missouri-based conservation initiative led by the Saint Louis Zoo. Working with the Endangered Wolf Center, scientists are looking to answer ecological and health-related questions about canids — red foxes, gray foxes and coyotes — as well as bobcats, which live in close association with canids.
