Intraguild predation (IGP) occurs when one predator species consumes another predator species with whom it also competes for shared prey. One question of interest to ecologists is whether multiple predator species suppress prey populations more than a single predator species, and whether this result varies with the presence of IGP. We conducted a meta-analysis to examine this question, and others, regarding the effects of IGP on prey suppression. When predators can potentially consume one…

Effects of combining an intraguild predator with a cannibalistic intermediate predator on a species-level trophic cascade.
TLDR
Empirical support is provided for the hypothesis that the addition of an intraguild predator may enhance prey suppression if the intermediate predator expresses density-dependent cannibalism.
The importance of intraguild predation in predicting emergent multiple predator effects
TLDR
It is found that the occurrence of intraguild predation decreased the overall risk to prey, causing observed multiple predator effects to deviate from predictions.
The Ubiquity of Intraguild Predation among Predatory Arthropods
TLDR
This study uses molecular analyses of gut contents to assess the nature and incidence of IGP among four species of coccinellid predators in soybean fields and represents the most convincing field evidence of a high prevalence of I GP among predatory arthropods.
Coexistence of Predator and Prey in Intraguild Predation Systems with Ontogenetic Niche Shifts
TLDR
Life-history omnivory provides a mechanism that allows intraguild predators and prey to coexist over a wide range of resource productivity and equilibrium patterns over productivity resemble those of three-species food chains.
The interaction of cannibalism and omnivory: consequences for community dynamics.
TLDR
Results indicate that including cannibalism in current models can overcome the discrepancy between theory and empirical data, and need to measure and account for cannibalistic interactions to reliably predict the structure and dynamics of communities.
The negative effects of pathogen‐infected prey on predators: a meta‐analysis
TLDR
The results suggest that communities containing parasitoids and pathogens may rarely exhibit intraguild predation; whereas, communities composed of strict predators and pathogens are more likely dominated by IGP dynamics.
Reciprocal intraguild predation and predator coexistence
TLDR
It is suggested that spatial structure and the presence of alternative food increase the coexistence period of intraguild predators.
Co-occurrence Among Intraguild Predators: Avoidance or Aggregation?
TLDR
It is found that most co-occurrence among IG predators was random, suggesting that avoidance does not limit co- Occurrence, and IGP likely.
Emergent impacts of cannibalism and size refuges in prey on intraguild predation systems
TLDR
The results indicate that cannibalism and ontogenetic niche shifts can result in behavior-mediated indirect interactions that reduce the impact of the predator on the mortality of its prey and alter the interactions of IGP systems, but also indicate that size is not the sole determinant and that the authors also need to account for the species identity when predicting the dynamics of communities.
Intraguild predation in the presence of a shared natural enemy.
TLDR
This work outlines the conditions under which the native species and/or its natural enemy are threatened by the arrival of the intraguild predator, and also when the natural enemy is beneficial in preventing the initial invasion or eventual dominance of the invader.

A Theoretical Framework for Intraguild Predation
TLDR
The consequences of incorporating IGP into standard models of exploitative competition and food chains (a general resource-consumer model, a Lotka-Volterra food chain model, and Schoener's exploitative Competition model) are explored and a general criterion for coexistence in IGP systems is suggested.
THE ECOLOGY AND EVOLUTION OF INTRAGUILD PREDATION: Potential Competitors That Eat Each Other
TLDR
The purpose is to document the ubiquity and importance of intraguild predation and to establish a theoretical framework for its analysis, which is the first synthesis of IGP into a general work.
Influence of intraguild predation among generalist insect predators on the suppression of an herbivore population
TLDR
It is concluded that intraguild predation in this system is wide-spread and has potentially important influences on the population dynamics of a key herbivore.
SCARED TO DEATH? THE EFFECTS OF INTIMIDATION AND CONSUMPTION IN PREDATOR–PREY INTERACTIONS
TLDR
The results suggest that the costs of intimidation, traditionally ignored in predator-prey ecology, may actually be the dominant facet of trophic interactions.

WHY SHORT‐TERM EXPERIMENTS MAY NOT ALLOW LONG‐TERM PREDICTIONS ABOUT INTRAGUILD PREDATION
TLDR
Simple models are used to examine the management relevance of this disconnection between theory and experiments in communities with intraguild predation and demonstrate why short-term experiments and studies ignoring alternate resources may bear no relationship to a system at equilibrium.
A cross-ecosystem comparison of the strength of trophic cascades
Although trophic cascades (indirect effects of predators on plants via herbivores) occur in a wide variety of food webs, the magnitudes of their effects are often quite variable. We compared the…
WHAT DETERMINES THE STRENGTH OF A TROPHIC CASCADE
TLDR
It is found that high system productivity and low species diversity do not consistently generate larger trophic cascades, and the strongest cascades occurred in association with invertebrate herbivores and endothermic vertebrate predators.

TLDR
It is argued that most cataloged webs are oversimplified caricatures of actual communities, and patterns from food webs of real communities generally do not support predictions arising from dynamic and graphic models of food-web structure.
Biodiversity and biocontrol: emergent impacts of a multi-enemy assemblage on pest suppression and crop yield in an agroecosystem
TLDR
Empirical evidence is presented that increasing the richness of a particular guild of natural enemies can reduce the density of a widespread group of herbivorous pests and, in turn, increase the yield of an economically important crop.
