BIO205H5 Lecture Notes - Lecture 16: Parental Investment, Crypsis, Tettigoniidae
Document Summary
We take that scenario and put it against time to see this type of cycle. Lotka-volterra models of predator-prey interactions: very simplified: why we see fluctuation in populations, do not account for: Functional responses: prey density vs rate of food consumption. Prey density changed how does the food consumption change in that preditor. Type 1: never change the rate of consumption, they keep eating until they are full, seen in a whale filter feeders. Type 3: they show a low rate of consumption when not alot of prey is available and peaks at mid level availability. Consumption is slow when prey density is low we would think they would eat more because they are hungry, Predator strategies: active hunting , ambush hunting sit and wait . Behaviour changed in the presence of a predator we see in the green the rate in decline of activity when there is threat of predator is nearby.
