The continued survival of species on islands depends on factors such as natural selection, genetic variation, natural disturbances (hurricanes, volcanic eruptions) and human-caused disturbances (introduced species, habitat loss). Human-caused disturbances tend to be the greatest cause of mortality, and understanding the causes of extinction ...
Guadalupe Island (Spanish: Isla Guadalupe) is a volcanic island located 241 kilometres (130 nautical miles) off the western coast of Mexico's Baja California peninsula and about 400 km (200 nmi) southwest of the city of Ensenada in the state of Baja California, in the Pacific Ocean.

An example of a keystone species in the North American deserts would be the coyote or mountain lion. These two predators can control the population and distribution of a large number of prey species. A single mountain lion can roam an area of hundreds of kilometers, in which deer, rabbits, and bird species are partly controlled by a predator of ...
Trinidad and Tobago is home to about 99 species of terrestrial mammals. About 65 of the mammalian species in the islands are bats (including cave roosting, tree and cavity roosting bats and even foliage-tent-making bats; all with widely differing diets from nectar and fruit, to insects, small vertebrates such as fish, frogs, small birds and rodents and even those that consume vertebrate blood).
The species is facing an extremely high risk of extinction in the wild. VU: Vulnerable: The species is facing a high risk of extinction in the wild. NT: Near threatened: The species does not meet any of the criteria that would categorize it as risking extinction but it is likely to do so in the future. LC: Least concern
