Guilty: Crabs are killing N.E. saltmarshes

Two newly published studies by a team of Brown University researchers provide ample new evidence that the reason coastal saltmarshes are dying from Long Island to Cape Cod is that hungry crabs, left unchecked by a lack of predators, are eating the cordgrass. (See sidebar on marsh die-off and greenhouse gasses.)

PROVIDENCE, R.I. [Brown University] — A marathon summer of field work by Mark Bertness, professor of ecology and evolutionary biology, and a squadron of students may finally help settle the heated debate about what’s killing the coastal saltmarshes of southern New England and Long Island. The group’s work has yielded two new papers that offer clear evidence of the cause. (more…)

Scientists Trace Evolutionary History of What Mammals Eat

*Feeding habits haven’t always been what they are today*

The feeding habits of mammals haven’t always been what they are today, particularly for omnivores.

Some groups of mammals almost exclusively eat meat–take lions and tigers and other big cats as examples.

Other mammals such as deer, cows and antelope are predominantly plant-eaters, living on a diet of leaves, shoots, fruits and bark. (more…)
