摘要: Breeding bird censuses were made in Puerto Rico, Panama, and temperate United States, a profile of foliage density was for each. Using information theory formulae both diversity indices measurements difference between habitats can be made. Based on these, the following verified directly from data: 1. Rico has nearly as many species per layer Panama regions, but Rican appear to recognize fewer layers certainly subdivide much less. Thus different are likely have quite similar unlike States.
