Abstract

Islands offer a wide range of habitats for wildlife. Most hold a different animals from mainland, but that depends of types, sizes and distances from nearest mainland. The „Equilibrium Theory“ proposed by MacArthur and Wilson attempts to explain this in the form of a mathematical model. The number of species living on an island at any given time is an equilibrium between immigration and extinction rate. In response of particular conditions on the islands animals slowly change over time, they evolve. We can find lot of endemic species on islands and because of that islands are biodiversity „hot spots“. Islands habitat are areas surrounded by an area of unsuitable habitat, they can be treated like real islands. That is important to know when we are trying to define the protected areas and maximize the carrying capacity of species in them. Biodiversity loss is a particular concern on islands and island habitats. There are “among the most threatened habitats in the world”, due to their small size, isolation and fragility. It is projected that the impacts of climate change and pollution will become increasingly severe and that the impacts associated with habitat change, over-exploitation and, particularly, invasive species will continue to be very high.
