Document Summary

Equals to n(t+1)/n(t) and is the geometric rate of increase. It can only be used with geometric models unlike r, which can be used with various other models. Stochastic models that is integrating probabilistic viewpoints when we are looking at population growth since probabilistic is much closer to reality. Two main parts on a leslie or transition matrix: fecundity and survivorship. Examine table 10. 2 to see the difference between r and k-selected life history. Understand the differences between the two different type of life histories. In turtle experiment, researchers found that large juveniles had the greatest impact on population because of its survivorship. If researchers focused on fecundity, there won"t be a positive impact on growth of population. Two main forms of competitive interactions: among individuals within population: intraspecific competition, among individuals from different species that are using the same resource: interspecific competition. Logistic population growth assumes that growth slows and stops as resources become limiting.
