What makes a successful invasion? What keeps invaders out? Are some geographic locations more vulnerable to invasion than others? Smithsonian marine biologists and colleagues at Temple University ...

A warming planet means a warming ocean. The seas soak up over 90 percent of the heat humanity traps on Earth. Last year, ocean warming reached a record high. "Unfortunately, I think we're going to ...

Almost all animals eat living things, so in a sense most are predators. We normally restrict the term, though, to cases in which the animal chases and kills its prey. Nevertheless, the models we will ...

The fossil record seems to indicate that the diversity of marine creatures increased and decreased over hundreds of millions of years in step with predator-prey encounters. For decades, there has been ...

Predation (including parasitism) is an ecological process through which biodiversity is shaped and maintained. Sentinel plasticine prey has been increasingly used to estimate predation pressure.

On an unassuming morning off the Norwegian coast, millions of small fish called capelin began to gather in the ocean. Soon enough, they amassed to 23 million individuals, forming a group over 6 miles ...

It’s pretty commonly known, and not very startling, that free-ranging cats eat birds and small rodents. But the degree to which they eat insects might surprise you. We are biologists who for many ...

Marine biologists tested predictions about biological invasions, first in Panama and then in an experiment of unprecedented geographic scale. Night and day, oil tankers, yachts and cargo ships stacked ...
