Predator-mediated apparent competition between two herbivores that feed on grapevines
Oecologia, 1994We have been releasing economically unimportant herbivorous mites of one species early in the season and protecting grapevines against another, more damaging herbivorous mite throughout the growing season. In this experiment, releases of economically unimportant Willamette mites alone, or of predatory mites alone, failed to reduce populations of the ...

Emergence asynchrony between herbivores leads to apparent competition in the field
Ecology, 2011It has been established that herbivore populations can be structured by apparent competition, even if they do not compete directly for resources. But we lack evidence on the mechanisms behind such indirect competition. This study shows that temporal asynchronies in emergence time lead to apparent competition via shared natural enemies in a leafminer ...

Apparent competition can compromise the safety of highly specific biocontrol agents
Ecology Letters, 2008Abstract Despite current concern about the safety of biological control of weeds, assessing the indirect impacts of introduced agents is not common practice. Using 17 replicate food webs, we demonstrate that the use of a highly host‐plant specific weed biocontrol agent, recently introduced into Australia, is associated with declines ...

Evaluating apparent competition in limiting the recovery of an endangered ungulate
Oecologia, 2012Predation can disproportionately affect endangered prey populations when generalist predators are numerically linked to more abundant primary prey. Apparent competition, the term for this phenomenon, has been increasingly implicated in the declines of endangered prey populations.

An Apparently Noncanonical Pattern of Morphotactic Competition
2019In canonical typology, a phenomenon that involves several dimensions of potential variation is seen as subsuming a range of deviations from a canonical ideal based on the definitional extremes of those dimensions. The canonical case of morphotactic competition is one in which (i) two rules of affixation are both eligible to apply in the realization of ...

The American Naturalist, 1998
This article investigates the relationship between the similarity of resource capture abilities and the amount of competition between two consumer species that exploit common resources. Most of the analysis is based on a consumer-resource model introduced by Robert MacArthur.

Ecology, 1987
Field experiments were performed to explore the nature of indirect interactions between two groups of ecologically distinct prey that occur on subtidal rocky reefs at Santa Catalina Island, California. Mobile gastropods (Tegula aureotincta, Tegula eiseni, and Astraea undosa) and sessile bivalves (mostly Chama arcana) share a common set of invertebrate ...

HERBIVORE-MEDIATED APPARENT COMPETITION BETWEEN TWO SALT MARSH FORBS
Ecology, 2003Indirect negative interactions between prey species that share a predator, referred to as apparent competition, have been modeled extensively. However, experimental studies examining the importance of apparent competition in the field are sparse, especially in plant–herbivore systems. In this study, I examined the role of a beetle herbivore, Erynephala
