In addition to posting sentinels at the nest entrance, as do most social insects, colonies of this species also have guards that hover near the entrance all the time.

A study by researchers in...

How wolf predation shapes elk antler evolution

What happens when you mix a biologist who studies beetle horns with scientists who spend their time exploring predator-prey dynamics? You get a better understanding of why elk shed their antlers much later than males of any other North American species.

University of Montana researchers and their partners recently published a study in Nature Ecology and...

Giving tortoises a 'head start'

Research from the University of Georgia indicates that head-starting -- raising a species in captivity and releasing it into a protected habitat after it has grown large enough to be less vulnerable to predators -- is a useful intervention for boosting the state's gopher tortoise population, which has been declining in numbers for decades due...

Fossil teeth show how Jurassic reptiles adapted to changing seas

Marine predators that lived in deep waters during the Jurassic Period thrived as sea levels rose, while species that dwelled in the shallows died out, research suggests.

A study of fossilised teeth has shed light on how reptiles adapted to major environmental changes more than 150 million years ago, and how sea life might respond today.

It...
