BIODIVERSITY VOCABULARY ADAPTATION • A behavior or physical characteristic that allows an organism to live successfully in its environment. BIODIVERSITY • The number of different species in an area. CAPTIVE BREEDING • The mating of animals in zoos or wildlife preserves. ENDANGERED SPECIES • A species in danger of becoming extinct in the near future. EXOTIC SPECIES • Species that are carried to a new location by people. (invasive, introduced) EXTINCTION • The disappearance of all members of a species from Earth. GENE • A structure in an organism’s cells that carries its hereditary information. GENE POOL • Organisms, within one species, share many common genes but also have some unique genes that make them individuals. HABITAT DESTRUCTION • The loss of a natural habitat. HABITAT FRAGMENTATION • The breaking of a habitat into smaller, isolated pieces. KEYSTONE SPECIES • A species that influences the survival of many others in the ecosystem. NICHE • The role of an organism in its habitat, or how it makes its living. POACHING • Illegal killing or removal of wildlife from their habitats. PRESERVATION • Protection from harm or damage. SPECIES • A group of organisms that are physically similar and can mate with each other and produce offspring that can also mate and reproduce. THREATENED SPECIES • A species that could become endangered in the near future.
