BIOL 123 Lecture Notes - Lecture 31: Predator Satiation, Outline Of Air Pollution Dispersion, Herbivore
Document Summary
The dynamics of predator-prey populations are intimately connected. Data from canadian trappers, catching rabbits/hares and links (feed on hares) Get money from trapping the hares, and consistent efforts of catching them. Records show numerical records on the numbers of capture of hares and links in canda. Idea is that the number of hares and links caught was proportional to what was there. The lotka-volterra model of predator-prey dynamics predicts cycles, although for. Delay in links following the cycle of the hare reasons that probably do not apply to natural populations. Early model developed to show predator-prey dynamics. Assumed prey grew exponentially, while the predators only food was the prey. Cycles aren"t stable, due to neutral stability. More realistic models incorporate density-dependent prey dynamics and predator satiation. What change was the density dynamics and the capture and density of prey. Model says there is no bound to how much prey that can be captured.
