Predator-prey interactions in a nonequilibrium context: the metapopulation approach to modeling "hide-and-seek" dynamics in a spatially explicit tri-trophic system

Article Abstract:

A comparison is presented between stochastic and deterministic models of population dynamics, applied to predation. The stochastic model predicts that predator and prey will succeed in existing together despite local extinctions, while the deterministic model predicts violent fluctuations that indicate the population system is unstable. The role of dispersal and asynchrony in demographic stochasticity is discussed.

Physiologically structured models - from versatile technique to ecological theory

Article Abstract:

An evaluation is presented on physiologically structured population models (PSPMs) and their use in developing size-dependent, individual-based community theory for ecological processes. PSPMs are found to provide a higher level of precision, realism and testing ability than other models, such as non-structured or lumped stage-based models.

Does population ecology have general laws?

Article Abstract:

The author explores several propositions that underlie the theoretical foundations of population dynamics models. These include exponential growth, resource-consumer oscillations, and self-limitation, and the author examines their resemblance to other scientific propositions such as the laws of physics.
