Bio 227 wildlife conservation biology- lecture notes 9/23/15. Wildlife: free ranging, non-domesticated especially terrestrial birds and mammals ex. But can"t really separate from other plant and animal associates (habitat, food, etc. ) Variation of life at all scales, the variety and variability of life. Ecosystem: a biological community of interacting organisms and their physical environment: diversity of species. Simply determined by the number of different species in an ecosystem: genetic diversity. Genetic variability within a species, what you can and can"t see (ex. Tasmanian devils = low genetic diversity leading to low immunity to a viral cancer. Cheetahs = low genetic diversity leading to ability to easily get a skin graft that matches. Sea otters = low genetic diversity leading to low immunity to parasites. Shows importance of genetic diversity in order to conserve species. Instrumental values (benefits to humans: consumptive benefits (food, medicine, engineering and other products {ex. ), pest control (barn owls keep rodent population down.
