Holling identified this mechanism in shrews and deer mice feeding on sawflies. At low numbers of sawfly cocoons per acre, deer mice especially experienced exponential growth in terms of the number of cocoons consumed per individual as the density of cocoons increased. Se mer A functional response in ecology is the intake rate of a consumer as a function of food density (the amount of food available in a given ecotope). It is associated with the numerical response, which is the reproduction rate … Se mer Type II functional response is characterized by a decelerating intake rate, which follows from the assumption that the consumer is limited by its capacity to process food. Type II functional response is often modeled by a rectangular hyperbola, … Se mer Type I functional response assumes a linear increase in intake rate with food density, either for all food densities, or only for food densities up … Se mer Type III functional response is similar to type II in that at high levels of prey density, saturation occurs. But now, at low prey density levels, the … Se mer • Ecosystem model • Lotka–Volterra equations • Predator satiation Se mer Nettet1. jun. 2024 · Dynamics of a predator–prey Model with Holling Type II Functional Response Incorporating a Prey Refuge Depending on Both the Species.
