Differential impact of a shared nematode parasite on two gamebird hosts: implications for apparent competition [PDF]

, 2001
If the deleterious effects of non-specfic parasites are greater on vulnerable host species than on reservoir host species then exclusion of the vulnerable host through apparent competition is more likely. Evidence suggests that such a mechanism occurs in

Impact of wild prey availability on livestock predation by snow leopards [PDF]

Royal Society Open Science, 2017
An increasing proportion of the world's poor is rearing livestock today, and the global livestock population is growing. Livestock predation by large carnivores and their retaliatory killing is becoming an economic and conservation concern.

Interactions between native and invasive species: A systematic review of the red squirrel-gray squirrel paradigm

Frontiers in Ecology and Evolution, 2023
The eastern gray squirrel (Sciurus carolinensis) has been labeled as one of the 100 worst invasive alien species by the IUCN. In Europe, the species has been introduced to Britain, Ireland and Italy, and its subsequent spread has resulted in wide-scale ...

Short‐term apparent mutualism drives responses of aquatic prey to increasing productivity

, 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.

Short-term indirect interactions between two moth (Lepidoptera: Noctuidae) species mediated by shared parasitoids: The benefit of being scarce

European Journal of Entomology, 2003
Despite the impact of parasitoids on insect populations being extensively studied, indirect parasitoid-mediated effects remain rarely documented in natural communities.

Natural enemies and biodiversity: The double-edged sword of trophic interactions

Mètode Science Studies Journal: Annual Review, 2019
Natural enemies, that is, species that inflict harm on others while feeding on them, are fundamental drivers of biodiversity dynamics and represent a substantial portion of biodiversity as well.

The relative importance of seed competition, resource competition and perturbations on community structure [PDF]

, 2011
While the regional climate is the primary selection pressure for whether a plant strategy can survive, however, competitive interactions strongly affect the relative abundances of plant strategies within communities.

Predation determines different selective pressure on pea aphid host races in a complex agricultural mosaic. [PDF]

PLoS ONE, 2013
Field assessments were conducted to examine the interplay between host plant and predation in complex agricultural mosaic on pea aphid clover and alfalfa races. In one experiment, we examined the relative fitness on clover race (CR) and alfalfa race (AR)

Competition among Aedes aegypti larvae. [PDF]

PLoS ONE, 2018
Adult Aedes aegypti mosquitoes are important vectors of human disease. The size of the adult female affects her success, fitness, and ability to transmit diseases. The size of the adults is determined during the aquatic larval stage.
