BIOL215 Lecture 15 Notes
λ 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
Logistic population growth assumes that growth slows and stops as resources become limiting
