Alternative prey influence the predation of mosquito larvae by three water bug species (Heteroptera: Nepidae)

open access: yesLimnological Review, 2020
The indirect interactions among multiple prey sharing a common predator characterize apparent competition. In conservation biological control involving mosquitoes and controphic prey against generalist insect predators, apparent competition may be a ...

Sperm‐dependent asexual species and their role in ecology and evolution

open access: yesEcology and Evolution, 2023
Sexual reproduction is the primary mode of reproduction in eukaryotes, but some organisms have evolved deviations from classical sex and switched to asexuality.

Global change risks a threatened species due to alteration of predator–prey dynamics

open access: yesEcosphere, 2023
Although global change can reshape ecosystems by triggering cascading effects on food webs, indirect interactions remain largely overlooked. Climate‐ and land‐use‐induced changes in landscape cause shifts in vegetation composition, which affect entire ...

Multitrophic interactions among plants, aphids, alternate prey and shared natural enemies - a review

open access: yesEuropean Journal of Entomology, 2008
Given the generalist tendencies of most predatory arthropods, it is widely thought that their impact on a particular prey species in a given habitat (e.g., an insect pest in a crop) will depend frequently on the local availability of other prey (which ...

Associational Effects and Indirect Interactions-The Dynamical Effects of Consumer and Resource Traits on Generalist-Resource Interactions

open access: yesFrontiers in Ecology and Evolution, 2022
Trophic interaction modifications occur in food webs when the direct or indirect interaction between two species is affected by a third species. These behavioral modification effects are often referred to as associational effects.

Resource competition in plant invasions: emerging patterns and research needs

open access: yesFrontiers in Plant Science, 2014
Invasions by alien plants provide a unique opportunity to examine competitive interactions among plants. While resource competition has long been regarded as a major mechanism responsible for successful invasions, given a well-known capacity for many ...

Apparent Competition in Two-Sided Platforms [PDF]

open access: yesSSRN Electronic Journal, 2017
We study a platform’s design of membership and transaction fees when sellers compete and buyers cannot observe the prices and features of goods without incurring search costs. The platform alleviates sellers’ competition by charging them transaction fees that increase with sales revenue, and extracts surplus via membership fees.

Interaction of perceptual grouping and crossmodal temporal capture in tactile apparent-motion [PDF]

open access: yes, 2011
Previous studies have shown that in tasks requiring participants to report the direction of apparent motion, task-irrelevant mono-beeps can "capture'' visual motion perception when the beeps occur temporally close to the visual stimuli. However, the

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

open access: yesRoyal 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.

Seeing motion and apparent motion [PDF]

open access: yes, 2014
In apparent motion experiments, participants are presented with what is in fact a succession of two brief stationary stimuli at two different locations, but they report an impression of movement. Philosophers have recently debated whether apparent motion
