- A group of individuals capable of interbreeding and producing fertile offspring.
- Beetles (33%), insects (74%), arthropods (86%), vertebrates (4%)
- Habitat loss/alteration/fragmentation, Introduced Species, Over-harvesting
- Larger islands have more species than smaller islands because rates of colonization
are higher and extinction rates are lower. Islands closer to the mainland
have more species because rates of colonization are higher and extinction
rates are lower. Vice versa for small and far islands.
- First, don't fragment habitat. Second, larger reserves are better than smaller
reserves and provide corridors between reserves.
- Definitions
- Species: "any subspecies" and "any distinct population
segment of any species"
- Endangered Species: "any species which is in danger of extinction
throughout all or a significant portion of its range..."
- Threatened Species: "any species which is likely to become an endangered
species within the foreseeable future throughout all or a significant
portion of its range."
