 Living beings can, however, alter environmental conditions as well as transform
 potential resources. Environmental diversity can, therefore, be the product of biological diversity. This seems to be the case of the rocky shores of New England where tide pools are present with two kinds of species compositions. Pools that have abundant periwinkle snails are dominated by perennial algal species, which are generally more resistant to herbivory. However, in the absence of snails, ephemeral fast growing algae cover the pools and provide shelter for predatory crabs, which in turn control snail population.

 In order to understand the coexistence of both kinds of pools and their resident
-species, we must consider ecological interactions set in a larger scale. Pools on a shore trade species by migration. Under which circumstances is a pool ensemble with both physiognomies stable? What if different species follow different movement patterns,does this stabilize or destabilize the system?
