Parasite transmission between trophic levels stabilizes predator–prey interaction

This module was created for grades , but may be adapted to the college level. Soil ecologists are interested in the ways that soil organisms interact and affect each other. One important relationship is that of predator and prey. In this module, students define the terms predator and prey and identify examples from soil ecology. They are introduced to the concept of a mathematical model so that they can identify situations where one may be useful. Students will create a hypothesis about how prey numbers will affect a predator population, then use a given mathematical model to perform calculations that will either support or refute their hypothesis.

Predator-Prey Interactions

The Lotka—Volterra equations , also known as the predator—prey equations , are a pair of first-order nonlinear differential equations , frequently used to describe the dynamics of biological systems in which two species interact, one as a predator and the other as prey. The populations change through time according to the pair of equations:. The Lotka—Volterra system of equations is an example of a Kolmogorov model , [1] [2] [3] which is a more general framework that can model the dynamics of ecological systems with predator—prey interactions, competition , disease, and mutualism. The Lotka—Volterra predator—prey model was initially proposed by Alfred J. Lotka in the theory of autocatalytic chemical reactions in D'Ancona studied the fish catches in the Adriatic Sea and had noticed that the percentage of predatory fish caught had increased during the years of World War I — This puzzled him, as the fishing effort had been very much reduced during the war years.

Predator-Prey Relationships System

The influence of predator-prey systems and interactions on wildlife passage use by mammals has received little attention to date. Predator-prey systems vary throughout the world and across regions. Europe and North America are characterised largely by predator-prey systems in which predator and prey have co-evolved.

biomass. Can prey populations support the desired growth and production of predators? If. predator–prey relationships can be quantified, are.



We investigate the influence of asymmetric interactions on coevolutionary dynamics of a predator-prey system by using the theory of adaptive dynamics.

under the definition can be modeled using a common mathematical framework. Most parasite-host relationships (which fall under some definitions of predation).
