Short-Term Apparent Competition

The American Naturalist, 1987
Interspecific interactions reflect the cumulative consequences of individual behavioral acts. The foraging decisions made by predators influence the way in which predation shapes the structure of prey communities. Alternative prey species co-occurring in a patch embedded in a matrix of many similar patches may interact through a shared mobile predator ...

Apparent competition and recovery from infection

Journal of Theoretical Biology, 2004
We use mathematical models to analyse how the recovery rate from infection influences the fitness of a host in a setting of interspecific competition. We show that sub-optimal immunity against pathogens can be advantageous for the host in the presence of cross-species infection. Weaker immunity allows the parasite to be used as a biological weapon, and

Endangered, apparently: the role of apparent competition in endangered species conservation

Animal Conservation, 2010
AbstractConservation biologists have reported growing evidence of food‐web interactions as causes of species endangerment. Apparent competition is an indirect interaction among prey species mediated by a shared predator, and has been increasingly linked to declines of prey species across taxa.

Apparent Competition between Two Aphid Species

The Journal of Animal Ecology, 1997
1. The population dynamics of colonies of nettle aphids (Microlophium carnosum Buckton) were studied on potted nettle plants placed beside plots of grass on some of which outbreaks of grass aphids (Rhopalosiphum padi L.) had been induced by fertilizer application. 2.

Predation on nests: a case of apparent competition

Oecologia, 1994
We describe a field experiment designed to evaluate indirect effects in a prey community sharing common predators. A simple prey community was mimicked with two types of artificial nests. Firstly, it was shown that predation rate increased with nest density when only a single prey was present.

Conservation Strategies for Species Affected by Apparent Competition

Conservation Biology, 2013
Abstract Apparent competition is an indirect interaction between 2 or more prey species through a shared predator, and it is increasingly recognized as a mechanism of the decline and extinction of many species. Through case studies, we evaluated the effectiveness of 4 management strategies for species affected by apparent competition:

Understanding intraspecific and apparent competition

2022
AbstractInterspecific competition shares the same dependence on consumer–resource interactions as intraspecific competition and apparent competition. These two related interactions are the subject of this chapter. Both interactions are present in most, if not all, systems in which interspecific competition occurs.

APPARENT COMPETITION WITH AN EXOTIC PLANT REDUCES NATIVE PLANT ESTABLISHMENT

Ecology, 2008
Biological invasions can change ecosystem function, have tremendous economic costs, and impact human health; understanding the forces that cause and maintain biological invasions is thus of immediate importance. A mechanism by which exotic plants might displace native plants is by increasing the pressure of native consumers on native plants, a form of ...

Invasion by the Variegated Leafhopper and Biotic Interactions: Parasitism, Competition, and Apparent Competition

Ecology, 1990
In 1980 the variegated leafhopper (VLH), Erythroneura variabilis, invaded California's San Joaquin Valley, and has since rapidly increased in numbers to become a major pest in vineyards. Correlated with the invasion by VLH are declining populations of congeneric grape leafhopper (GLH), E. elegantula.
