Document Summary
Nature preserves are an example of habitat islands. Number of species is a product of imigration and extinction. More species on an island means the lower the immigration rate however extinction rate also goes up the more species there are on the island. Species richness varies as function of # of existing species island size and remoteness. Elon wilson and simberloff mangrove island test. Looked at 6 mangrove islands in the florida keys. Killed all the arthropods on the island. Let the arthropods recolonize the island to see the new diversity on the mangrove island. Found that habitat destruction is one of the largest known cause of extinction. Habitat destruction is primarily when the species original habitat becomes. Man made habitat islands to help maintain population. Should be relatively large and located close to other relatively large habitat areas. Ecological communities and abiotic factors linked by energy and nutrient flow. Ultimate source of energy is the sun.
