Biodiversity around the world is increasingly threatened by global warming, habitat loss, and other human impacts. But what does this loss of species mean for the functioning of ecosystems that humans depend on for goods and services? Can ec…
Candid cameras give a chance to see wildlife as a scientist does
Researching animals in the wild can be challenging, especially if it involves a rare or elusive species like the giant panda or the clouded leopard. To remedy this, scientists rely heavily on camera traps — automated cameras with motion sensors…
Asthma tied to bacterial communities in the airway
