Interference competition and species coexistence.
Interference competition is ubiquitous in nature. Yet its effects on resource exploitation remain largely unexplored for species that compete for dynamic resources. Here, I present a model of exploitative and interference competition with explicit resource dynamics. The model incorporates both biotic and abiotic resources. It considers interference competition both in the classical sense (i.e. ...
متن کاملCompetition and coexistence in the chemostat∗
The aim of this course is to describe the mathematical model of competition in the chemostat and to study various mechanisms of coexistence of species. Basically, the chemostat consists of a nutrient input, pumped at a constant rate into a well-mixed culture vessel. The culture vessel contains the microorganisms that are growing and competing for the nutrient. Volume is kept constant by pumping...
متن کاملSpecies competition: coexistence, exclusion and clustering
We present properties of Lotka-Volterra equations describing ecological competition among a large number of interacting species. First we extend previous stability conditions to the case of a non-homogeneous niche space, i.e. that of a carrying capacity depending on the species trait. Second, we discuss mechanisms leading to species clustering and obtain an analytical solution for a state with ...
متن کاملEnvironmental stress, facilitation, competition, and coexistence.
The major theories regarding the combined influence of the environment and species interactions on population and community dynamics appear to conflict. Stress/ disturbance gradient models of community organization, such as the stress gradient hypothesis, emphasize a diminished role for competition in harsh environments whereas modern coexistence theory does not. Confusion about the role of spe...
متن کامل5 Competition and Coexistence of Mobile Animals
Competitive interactions among species lie at the foundation of our understanding of the structure and diversity of ecological communities. For the past century, various theoretical, laboratory and field studies have sought to understand how species that compete can coexist. Almost two decades ago, two influential reviews (Connell 1983; Schoener 1983) demonstrated that, at least in published st...
