How Nature Defies Math in Keeping Ecosystems Stable

Behind the beautiful facade of a rainforest, a savanna or a placid lake is a world teeming with contests and partnerships. Species are competing for space, consuming one another for resources, taking advantage of one another's talents, and brokering trades of nutrients. But there's something funny about this picture. When ecologists try to model ecosystems using math, they tend to find that the m

The origins of the High Plains landscape

Starting at the eastern foot of the Rocky Mountains in the Midwest United States, the dramatic landscape of the High Plains stretches across several U.S. states. Dropping just a few hundred meters over a length of more than 500 kilometres, these plains have only a very gentle gradient and the nearly flat surfaces exhibit unique ecosystems, making them a geological and ecological anomaly.

Efforts to make science relevant to diverse populations inadvertently create divisions, study finds

Around the turn of the 20th century, U.S. educators widely considered certain populations less educated, less healthy and unprepared to be true American citizens. If asked, most might argue those practices have disappeared as social norms have changed—particularly given that many reforms today focus on equity and diversity. A University of Kansas researcher has published a study showing how the ve
