Metaphysiological and evolutionary dynamics of populations exploiting constant and interactive resources:R—K selection revisited | Semantic Scholar

A two-state paradigm that represents each population or group in a food web in terms of both its quantity and quality is formed and physiological inefficiencies associated with this switching can be favored by selection due to the diminished exposure of inefficient consumers to strong oscillations associated with the well-known paradox of enrichment.

A general compact formulation of BTW in terms of a three-variable differential equation formulation for each species in the food web: viz. live biomass, dead biomass, and a food-intake-related measure called deficit-stress is provided.

The analyses suggest that realistic classes of consumer—resource models exist which do not obey Kolmogorov's Criteria but are nevertheless globally stable, and increases in maximum feeding rate may, under certain circumstances, result in decreases in consumer population.

The population dynamics of a general three-species, three-trophic-level exploitational system are explored and removal of carnivores is a perilous ecological gamble.

This review shows how the theory may be used to account for some of the observed dynamics of well-known laboratory sistems including their oscillatory periods and neighborhood stability and adds that addition of a biocide can actually increase the average population densities of the species one intended to attack.

This book builds a mechanistic, resource-based explanation of the structure and functioning of ecological communities and explores such problems as the evolution of "super species," the differences between plant and animal community diversity patterns, and the cause of plant succession.
