Document Summary

A branch of the life sciences that studies the short-term ad long-term changes in the size and age composition of population, and the biological and environmental processes influencing those changes . Population- a group of individuals of the same species that inhabit a defined area at a specific time. Usually higher than needed to replace the parents. Fecundity: potential number of offspring produced by an individual over time. Production: actual number of offspring produced in a given time. Different levels of fecundity and production (i. e. rabbits more rapid birth rate vs. elephants very few births over several years) Use of r or k depends on what you are comparing. Changes throughout the life cycle of an organism. 100 deer (food for 80 deer, 20 could starve to death) Instead of 35 deer drying, maybe now only 25 will die. 50% deer die regardless of other factor previously. The relative number of males and females.
