Document Summary
Bioc63fall2013 lecture 15: species and population approach to conservation. Evolution occurs at the population level biodiversity. Worldwide: prevention of extinction mostly centered around species. Convention on international trade in endangered species (cites) Conservation education: effort to engage public and fundraise. Life history characteristics of species as predictors of extinction likelihood. Island status = the more species are found on islands, the greater the extinction rate. Strongest predictor for species being at risk of extinction is geographic range. Things that makes species prone to extinction. Carnivores: geographic range, gestation length and trophic level. The means negative correlation, and the more dots the stronger the correlation. So for primates: geographic change, body mass and population density. Diet the more specialized a bird is the more likely it will become extinct. Brood number the lower the amount of baby birds, the higher the chance the bird will go extinct. Graph 1 the more specialized, the greater the decrease in pop.
