Cage vs open Pacific.jpg (IMAGE) Smithsonian Tropical Research Institute Caption To find out if predation changes the composition of the community of invertebrates, researchers enclosed some of the panels with a mesh cage. On the Pacific side of Panama, predation was greater than on the Atlantic side, and some species were only found in enclosed panels on the Pacific, rarely on open panels. Predation was also greater in the tropics than further north. The results of this study indicate that conserving the biodiversity of a site and protecting the predators may limit marine invasions.
