Document Summary
Captive breeding with reintroduction: habitat restoration, habitat protection. Reduction or elimination of harvesting removing disease agents. A population is a group of coexisting, interacting individuals of the same species at a given location and time. Population: all coexisting individuals of the same species living in the same area at the same time. N = birth + immigration death emigration. Historically, most population models assumed panmixus: all animals within a population equally likely to mate. There are barriers to panmixus, like spatial structure, road/traffic, clumped distributions of animals, and sub-populations located in isolated patches. Fragmentaion: n (population size) is a function of demographic (random fluctuations in age structure and birth death rates), For a population to persist ,its colonization rate must be equal or larger to it"s extinction rate. Things acting to lower the effective population (ne) size: Environmental variation and catastrophic events or: habitat destruction, environmental degradation, habitat fragmentation, over harvesting, effects of exotic species.
