Spatial heterogeneity and interspecific competition

Theoretical Population Biology, 1982
A model of two competing species is presented in which each species is able to disperse over a single spatial axis. The spatial axis is composed of two intervals with different carrying capacities. We ask the question: If species one is alone and at population dynamic equilibrium, then when can species two successfully invade when rare?

Speciation, Adaptation and Interspecific Competition

Oikos, 1984
Apres avoir considere les concepts d'espece et de speciation on envisage les effets possibles de la competition au niveau de l'historique de la speciation et de la post-speciation de l'espece.

Lotka–Volterra Interspecific Competition

2009
Different species frequently compete for limiting resources, and as a result have negative impacts on each other. For example, change in species composition during secondary succession (Fig. 5.1) appears mediated by, among other things, a species' ability to intercept light, grow, and cast shade over other species.

Mode of competition and interspecific competitive outcomes

1993
Abstract Competition (both intra- and interspecific) has been one of the most intensively studied subjects in ecological research (Connell 1983; Schoener 1983; Abrams 1988). This is the first and most important step in bridging the gap between community ecology and lower levels of ecological phenomena at the population and individual ...

Field Experiments on Interspecific Competition

The American Naturalist, 1983
The study of interspecific competition has long been one of ecology's most fashionable pursuits. Stimulated in part by a simple theory (Lotka 1932; Volterra 1926; Gause 1934; Hutchinson 1959; MacArthur and Levins 1967), ecologists gathered numerous data on the apparent ways species competitively coexist or exclude one another (reviews in Schoener 1974b,

Interspecific Competition and Community Structure

1984
Much of our previous discussion has relied, whether implicitly or explicitly, on considerations of ecological competition. In the last chapter particularly, such consideration became more and more explicit as we introduced ideas of both inter- and intraspecific competition and their role in shaping the niche, niche position, niche breadth and degree of

Interspecific competition and multispecies coexistence

2007
Interspecific competition is an interaction in which species inhibit each other such that increased abundance of one species leads to lower growth rates of the other species. Numerous field studies have shown that interspecific competition is a major force determining species abundances for a wide variety of taxa in many different ecosystems (Harper ...
