Sample text

Large fragments are generally rich in species and smaller fragments increasingly poor. 2. The rate of extinction is greater in small islands. Small islands will have longer edges in relation to their area, so the chances of predation are greater, as in the case of the spotted owl. 3. The greater the distance between islands, the lower are the chances of an animal reestablishing itself if it should become extinct at a site. The immigration rate on a smaller island is lower because wandering organisms are less likely to chance upon it.

The greater the distance between islands, the lower are the chances of an animal reestablishing itself if it should become extinct at a site. The immigration rate on a smaller island is lower because wandering organisms are less likely to chance upon it. 4. When a population of an organism is split into fragments, it is less likely to be wiped out by an epidemic disease. But there is a danger that the isolated patches will fail to link up to interbreed, and this can lead to isolated populations becoming genetically uniform.

This is most obvious when you fly over a city and can observe how the blocks of concrete that form the offices and dwellings are separated by road systems that, in turn, may carry trees and strips of grass along their edges. Gardens can occur even in the center of cities, perhaps even on rooftops, forming patches of green. They often become larger and more frequent as we move out into the suburbs and may be linked together in extended strips. Parks are also found in most cities, forming larger islands of vegetation within a sea of sterile brick.
