TLDR
A discrete (difference) single age-class model for two-species competition is presented and its stability properties discussed, which resembles the Lotka-Volterra model in having linear zero growth isoclines but differs in allowing the populations to show damped oscillations, stable cycles or even apparent “chaos” if competition is sufficiently severe.About:

The ontogenetic niche and species interactions in size-structured populations
Earl E. Werner,James F. Gilliam +1 more
TL;DR: The body size is one of the most important attributes of an organism from an ecological and evolutionary point of view as mentioned in this paper, and it has a predominant influence on an animal's energetic requirements, its potential for resource exploitation, and its susceptibility to natural enemies.

Bifurcations and Dynamic Complexity in Simple Ecological Models
Robert M. May,George Oster +1 more
TL;DR: It is shown that as a hump steepens, the dynamics goes from a stable point, to a bifurcating hierarchy of stable cycles of period 2n, into a region of chaotic behavior where the population exhibits an apparently random sequence of "outbreaks" followed by "crashes".

Aggregation, migration and population mechanics
L. R. Taylor,R. A. J. Taylor +1 more
TL;DR: A concept is developed for the regulation of populations by density-dependent movement, rather than by overt competition alone, which is seen as maximising the reproductive advantage of a balance between migratory and congregatory behaviours.

The Competitive Exclusion Principle
TL;DR: By emphasizing the very aspects that might result in their denial of them were they less plain the authors can keep the principle explicitly present in their minds untit they see if its implications are, or are noty as unpleasant as their subconscious might suppose.

The struggle for existence
TL;DR: For three-quarters of a century past more has been written about natural selection and the struggle for existence that underlies the selective process, than perhaps about any other single idea in the whole realm of Biology as discussed by the authors.
