## Extinction Risk

10/04/2011 by jgluvna

Many threatened species face extinction risks due to loss of habitat, disease, hunting pressure, etc., which ultimately result in dangerously low population sizes. Choose a threatened species with an extinction risk and create an equation/model that describes the change in their population size over time. At the current population growth rate, how long would it take for the population to go extinct. How much would the population growth rate or how many additional individuals would have to immigrate into the population for the population to avoid extinction?

### Theory

- logistic equation (Neuhauser, Claudia. Calculus for Biology and Medicine. New Jersey: Prentice Hall, 2000. 364-366)
