Density Dependent Factor - A factor that influences an individuals probability of survival and reproduction in a manner that depends on the size of the population (i.e. predation, disease, food supply) Density Independent Factor - A factor that has the same effect on a individual's probability of survival and reproduction at any populations size (i.e. hurricanes, floods, fires) exponential growth models - occurs when populations are not limited by resources. (J-curve) logistic growth mo...
