Document Summary
A branch of the life sciences that studies the short-term and 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. Usually higher than needed to replace the parents. Fecundity: potential number of offspring produced by an individual over time- changes over the animal"s lifespan. Production: actual number of offspring produced in a given time. Different levels of fecundity and production- rabbits and elephants. Use of r or k depends on what you are comparing. Changes throughout the lifecycle of an organism. 100 deer- food for 80 deer, 20 could starve. Instead of 35 deer dying, maybe only 23 will die. More food sources for the deer because the wolves are eating deer. Doesn"t matter what is going on, it adds onto the mortality rate.
