Interspecific competition, predation and species diversity

Journal of Theoretical Biology, 1970
Abstract A review was made of some mathematical population models and their applications to problems of interspecific competition and predator-prey relationships. These were considered in relation to some observations and experiments suggesting local increases in species diversity under predation in competitive situations.

Overlap in resource use, and interspecific competition [PDF]

Oecologia, 1974
When several species co-exist, the amount by which they overlap in their use of resources is a measure of their similarity to one another. As such, resource overlap does not measure the amount of competition among them. When the resources are not limiting to population growth, patterns of resource use may overlap to any degree.

Spatial distribution and interspecific competition

Ecological Entomology, 1987
The role of interspecific competition as a significant and consistent process in structuring communities of phytophagous insects has been reviewed and questioned by Strong et al.(1984).

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,

Cost of interspecific competition between trematode colonies

Journal of Helminthology, 2020
Abstract In a range of trematode species, specific members of the parthenitae colony infecting the molluscan first intermediate host appear specialized for defence against co-infecting species. The evolution of such division of labour requires that co-infection entails fitness costs.

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/facilitation among insect parasitoids

Current Opinion in Insect Science, 2016
Competition for limited resources is a widespread ecological interaction in animals. In the case of insect parasitoids, species can compete for host resources both at the adult stage as well as at the larval stage. Interspecific competition can play a role in sizing and shaping community structures.

Interspecific competition among urban cockroach species

Entomologia Experimentalis et Applicata, 2004
AbstractThe aim of this study was to quantify and to compare the effects of intraspecific and interspecific competition among pairs of urban cockroaches [Blatta orientalisL.,Periplaneta americana(L.), andPeriplaneta australasiaeFabricius (Dictyoptera: Blattodea)] in relation to the limitation of resources such as shelter or food.

Selection in Contexts of Interspecific Competition

The American Naturalist, 1974
By extending the concept of density-dependent fitness to include the density of a competitor species, one can study the operation of selection in situations of competition between two sexual species. A model is put forward considering one biallelic locus in each species and assuming these loci to affect competition somehow.
