Apparent Competition and Vector-Host Interactions [PDF]
Israel Journal of Ecology and Evolution, 2010 Infectious disease influences the dynamics of host populations and the structure of species communities via impacts on host demography. Species that share infectious diseases are well-known to interact indirectly through the process of apparent competition, but there has been little attention given to the role of vectors in these indirect interactions.

Apparent competition structures ecological assemblages [PDF]
Nature, 1997 Competition is a major force in structuring ecological communities1. It acts directly2 or indirectly, in which case it may be mediated by shared natural enemies and is known as ‘apparent competition’3,4,5,6. The effects of apparent competition on species coexistence are well known theoretically7,8 but have not previously been demonstrated empirically ...

Enemy‐mediated apparent competition: empirical patterns and the evidence [PDF]
Oikos, 2000 Apparent competition arises when two victim species negatively affect each other (−, −) by enhancing the equilibrium density or changing the foraging behaviour of a shared natural enemy. Shared enemies can also mediate non‐reciprocal (−, 0) indirect effects, i.e.

Refuge‐mediated apparent competition in plant–consumer interactions [PDF]
Ecology Letters, 2009 AbstractAt the intersection of consumer behaviour and plant competition is the concept of refuge‐mediated apparent competition: an indirect interaction whereby plants provide a refuge for a shared consumer, subsequently increasing consumer pressure on another plant species.

Population dynamics of apparent competition in a host–parasitoid assemblage [PDF]
Journal of Animal Ecology, 1998 Summary The population dynamics of two moth species, Plodia interpunctella (Hübner) and Ephestia kuehniella Zeller in the presence of their shared parasitoid, Venturia canescens (Gravenhorst), were studied in well replicated time series experiments.

Apparent Competition, Lion Predation, and Managed Livestock Grazing: Can Conservation Value Be Enhanced? [PDF]
Frontiers in Ecology and Evolution, 2019 Predator restorations often result in apparent competition, where co-occurring prey populations experience asymmetric predation pressure driven by predator preferences.

Apparent competition with an invasive plant hastens the extinction of an endangered lupine [PDF]
Ecology, 2010 Invasive plants may compete with native plants by increasing the pressure of native consumers, a mechanism known as “apparent competition.” Apparent competition can be as strong as or stronger than direct competition, but the role of apparent competition has rarely been examined in biological invasions.

Experimental evidence for apparent competition in a tropical forest food web [PDF]
Nature, 2004 The herbivorous insects of tropical forests constitute some of the most diverse communities of living organisms. For this reason it has been difficult to discover the degree to which these communities are structured, and by what processes. Interspecific competition for resources does occur, but its contemporary importance is limited because most pairs ...

Short‐term apparent mutualism drives responses of aquatic prey to increasing productivity [PDF]
, 2021 According to apparent competition theory, sharing a predator should cause indirect interactions among prey that can substantially influence food-web responses to environmental drivers.

Land‐use intensity affects the potential for apparent competition within and between habitats [PDF]
, 2021 Arthropod communities dwelling in adjacent habitats are able to impact one another via shared natural enemies. In agricultural landscapes, drastic differences in resource availability between crop and non-crop habitats cause variation in insect herbivore
