Because of limited resources on islands, carrying capacity will be lower, decreasing population sizes and increasing ...

These colonizing species may then evolve into several new species. • Thus, islands often hold a very distinct but limited set of species. • Many island species, such as the Hawaiian honeycreeper, a ...

Fauna of Africa
Fauna of Africa, in its broader sense, is all the animals living in Africa and its surrounding seas and islands. The more characteristic African fauna is found in the Afrotropical ecoregion. Lying almost entirely within the tropics, and equally to north and south of the equator creates favourable conditions for rich wildlife.
