The Lotka-Volterra model of predator and prey interactions is a classic one, but adds another variable to the 3 constants in the above model. The new variable is a predator-prey encounter rate. In the Lotka-Volterra model, it's easy to give it values that drive predator or prey below zero, which makes no sense, or to drive prey to such small ...

The Lotka-Volterra model describes interactions between two species in an ecosystem, a predator and a prey. This represents our first multi-species model. Since we are considering two species, the model will involve two equations, one which describes how the prey population changes and the second which describes how the predator population changes. -
This mathematical model, the Lotka-Volterra, can then be analyzed analytically or using computer simulation to determine period lengths, phase portraits, critical points, and other practical information to the reality of the relationship.
Prey defenses can be a stabilizing factor in predator-prey interactions. Predation can be a strong agent of natural selection. Easily captured prey are eliminated, and prey with effective defenses (that are inherited) rapidly dominate the population. Examples include camouflage in the peppered moth, and prey that are nocturnal to escape detection.

TYPE II FUNCTIONAL RESPONSE: HOLLING'S DISK EQUATION. Introduction: In the type II functional response, the rate of prey consumption by a predator rises as prey density increases, but eventually levels off at a plateau (or asymptote) at which the rate of consumption remains constant regardless of increases in prey density (see also TYPE I and TYPE III FUNCTIONAL RESPONSE).
