Invasion dynamics

Researchers suspended panels in the ocean on the Atlantic and Pacific sides of Panama to collect invertebrates.

CST researchers part of team of biologists to discover that more intense predation in the tropics can limit marine invasions

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, including Associate Professor Amy Freestone and doctoral candidate Michele Repetto, tested predictions about biological invasions, first in Panama and then in an experiment of unprecedented geographic scale. Their results are published in companion papers in the journal Ecology.

In general, the Pacific panels collected fewer invertebrates than panels placed on the Atlantic side of Panama. Credit: Carmen Schloeder, STRI.
