The ability of predators to reduce prey populations is generally ascribed to the consumption of prey individuals. However, predators may also induce behavioral chang- es in prey individuals, which can reduce prey survival and reproduction. Pea aphid pop- ulations are impacted by a variety of predators, many of which induce escape responses in individual aphids. We created disturbance-only predators (surgically manipulated pred- ators that were unable to consume prey, but were still able to…

Predator avoidance behavior in the pea aphid: costs, frequency, and population consequences

The potential for predators to suppress prey populations through induction of prey defenses may be strongest in systems where (1) predators frequently induce prey defensive responses, and (2) prey defenses incur acute survival or reproductive costs.

Multiple predator species alter prey behavior, population growth, and a trophic cascade in a model estuarine food web

It is demonstrated that multiple predator species can nonconsumptively influence prey population growth and the strength of a trophic cascade in a model marine community.

Predation risk cues associated with killed conspecifics affect the behavior and reproduction of prey animals

This experiment is the first to demonstrate that the presence of congeners killed by an enemy can contribute to the suppressive effects of natural enemies on prey populations.

Non-consumptive predator effects on prey population size: a dearth of evidence.

It is highlighted the critical need to appreciate risk effects at each level in the chain of events, and that changes at one level cannot be assumed to translate into changes in the next because of the interplay between risk, prey responses, and the environment.

Size-dependent fitness trade-offs of foraging in the presence of predators for prey with different growth patterns

Prey species make choices about whether to employ costly predator avoidance behaviors throughout their growth and lifecycle. Here, we explore the effects of prey size at a given age (ontogenetic

Dropping Behavior in the Pea Aphid: How Does Environmental Context Affect Anti-Predator Responses?

This thesis work explored the relationship between dropping behavior, alarm cues (an indication of predator threat), aphid density, and plant health in the pea aphid and found that the presence of an alarm cue resulted in significantly more dropping than with alarm cue absent.

The long‐term impacts of predators on prey: inducible defenses, population dynamics, and indirect effects

The results demonstrate that although predators can have significant effects on prey phenotypes and sometimes cause short-term TMIIs, there may be few long-term consequences of these responses on population dynamics and indirect interactions, at least within simple food webs.

A simple plant mutation abets a predator-diversity cascade.

This study provides evidence that diversity effects in predator assemblages are sensitive to habitat characteristics, and shows that a simple plant morphological trait can dramatically alter the cascading effects of predator species richness on herbivores and plants.

The Many Faces of Fear: Comparing the Pathways and Impacts of Nonconsumptive Predator Effects on Prey Populations

A simple Lotka-Volterra predator-prey model is built on to provide a heuristic tool for distinguishing between the demographic effects of consumption and of anti-predator defenses, and for distinguishing among the multiple mechanisms by which anti-Predator defenses might reduce prey population growth rates.



Nonlethal Effects in the Ecology of Predator-Prey Interactions What are the ecological effects of anti-predator decision-making?

A perusal of any recent textbook on ecology will not only confirm the importance of predation in modern ecology, but also illustrate the preeminence of the "lethal" perspective on predation.

Experimental evidence for a behavior-mediated trophic cascade in a terrestrial food chain.

The results demonstrate that the behavioral response of prey to predators can have a strong impact on the dynamics of terrestrial food chains and make a compelling case to examine behavioral as well as density effects in theoretical and empirical research on food chain dynamics.

Antipredator Behavior and the Population Dynamics of Simple Predator-Prey Systems

It is shown that increased efficiency of antipredators behaviors increases prey densities and decreases the ratio of predator-to-prey densities, and that antipredator behaviors tend to decrease the oscillatory dynamics inherent in model predatorprey systems.

Sublethal Consequences of Stream‐Dwelling Predatory Stoneflies on Mayfly Growth and Fecundity

These data convincingly demonstrate that predator avoidance can have dramatic consequences on mayfly fitness and suggest that natural selection has shaped the foraging behavior of organisms to maximize fitness.

Short Term Refuge Use and Stability of Predator-Prey Models

An individual-level behavioural model representing prey becoming temporarily less susceptible to attack in response to detection of predators is presented and the effect of the hiding response on the vital rates of the prey population is also derived from the behavioural model.

Interaction Between Food Availability and Predation Mortality Mediated by Adaptive Behavior

The results suggest the possibility that adaptive variation in behavior may lead to density—dependent population regulation and incorporate this variation into population dynamic modelling may improve the ability to predict the outcome of interactions within ecological communities.


The results indicate that the importance of ground-foraging predators in agroecosys- tems may need to be reevaluated and that positive interactions between predators must be considered in models predicting the impact of multiple predator complexes.

Emergent impacts of multiple predators on prey.

Intraguild Predation and Competition Between Larval Dragonflies: Direct and Indirect Effects on Shared Prey

It is found that the combined predatory effects of the two dragonflies on damselflies were not additive, and an asymmetric potential for intraguild predation can lead to asymmetries in interference competition and to non-additive effects on prey mortality.

Existing literature on risk and reproductive behaviour and suggestion directions for future study are reviewed and some effects of predation risk on prey population patterns due to changes in prey reproductive behaviour are discussed.
