Invertebrates, such as dung beetles and grasshoppers, play a crucial role in recycling nutrients in ecosystems.  Our research aims to understand what factors influence the populations of these important invertebrates in grasslands. We study how grazing, use of insecticides, types of plants, and local climate affect insect populations, which can inform conservation strategies and how we manage rangelands.
communities play different roles depending on whether the grasslands are grazed by bison

Cuckoos are extremely secretive birds and difficult to spot. Researchers are developing a tool, using remote sound recorders and artificial intelligence, to help detect them.

Black-tailed prairie dogs are one of five species, the others being Utah, Mexican, white-tailed and Gunnison’s prairie dogs. These social rodents are industrious diggers, excavating prairie dog towns, which are U-shaped with chambers connected by tunnels.
poisoning and shooting) because of the perceived competition with grazing cattle and bison

Once believed extinct, the black-footed ferret is one of North America’s most endangered mammals, with fewer than 300 individuals living in the wild today. Thanks to reintroduction efforts, small populations now exist across parts of western North America.  However, their survival depends on one key species: prairie dogs.

Guam rails are small, speedy ground birds who can only fly three to 10 feet at a time. They are also only the second bird in history – after the California condor – to recover from being extinct in the wild. The Smithsonian’s National Zoo and Conservation Biology Institute is an active participant in the Guam Rail conservation program. Some of the Guam rails raised at the Smithsonian Conservation Biology Institute in Front Royal, Virginia, go on to be released into the wild on small islands off the coast of Guam. In working with birds like Guam rails, animal care staff monitor their health and behavior closely, weighing the birds regularly and observing them daily. A few years ago, they diagnosed one Guam rail with heart disease.

Smithsonian scientists and partners have developed a mathematical model to help understand why certain landscapes are especially vulnerable to losing their forests and the species that rely on them, while others are more resilient.

Researchers in Virginia wanted to learn how common field management practices — like mowing, burning or animal grazing — affect birds that stay for the winter. They turned to local farmers and landowners for help.

A new study from SCBI and partners compares the bacterial communities (microbiome) in the gut of wild rhinos to that of those in human care, resulting in a recommendation for a health-boosting rhino diet.

In the midst of the pandemic, as the story goes, a team set out to bring swift foxes back to a land they had disappeared from more than 50 years ago. Learn more in this update from landscape ecologist Hila Shamon.
