NRC 261 Lecture Notes - Logistic Function, Exponential Growth, Inbreeding
Document Summary
Population: a group of individuals of a species. Sometimes easy to identify sometimes not so easy/ Meaningful is it meaningful to discuss to talk about size, growth rates, density, distribution and vital statistics. Comparable-population can be compared with other populations or in another time its own population. Isolated largely reproductively isolated from other populations of same species. Robins- flock of robins is not a population. Snapping turtles- in campus pond is a population. Mallard ducks- maybe could because they are inbred ducks. But they do classify routes as a population of species. Whooping crane-once upon a time the entire species was the population. Today, people have started setting up new migration routes and many populations. Population dynamics - how and why populations change in numbers and distribution. Brown bats- understanding how they live in different geographic areas helps population dynamics. (all species) Increasing at fast rates unlimited resources and no mortality.
