The risk allocation hypothesis predicts that prey responses to predation risk should depend on the temporal pattern of risk. In systems where activity is dangerous, predicted activity levels should be ranked as follows: activity during a pulse of safety>activity during continual safety>activity during continual risk>activity during a pulse of risk. We conducted the first experimental test of the basic predictions of the risk allocation hypothesis by examining responses of freshwater physid… 

Does Temporal Variation in Predation Risk Influence the Intensity of Antipredator Responses? A Test of the Risk Allocation Hypothesis

It was found that trout exposed to risky situations more frequently responded with significantly less intense antipredator behaviour than troutexposed to risk infrequently, and the intensity of response of trout exposures to moderate risk decreased to levels similar to situations of no risk.

Variation in predation risk and vole feeding behaviour: a field test of the risk allocation hypothesis

It is argued that the deviation between the observed pattern of feeding behaviour of bank voles and that predicted by the predation risk allocation hypothesis was mostly due to the inability of voles to accurately assess the changes in the level of risk.

The effects of variable predation risk on foraging and growth: less risk is not necessarily better.

It is suggested that effects on growth are most important to how prey ultimately allocate risk, and exclusive focus on behavioral responses to risk will likely provide an incomplete understanding of how NCEs shape individual fitness and the dynamics of ecological communities.

The dynamic nature of antipredator behavior: prey fish integrate threat-sensitive antipredator responses within background levels of predation risk

It is interesting to note that the background level of risk over the past 3 days influenced the threshold level of response to varying concentrations of alarm cues, which illustrated a remarkable interplay between immediate (current) risk and background risk in shaping the intensity of antipredator responses.

Frequency of Encounter with Risk and the Tradeoff between Pursuit and Antipredator Behaviors in Crayfish: A Test of the Risk Allocation Hypothesis

The results do not support the predictions of the RAH for the authors' frequency regimes, but qualitative comparison with an earlier, similar study suggests that risk allocation is occurring in this system.

Fixed vs. Random Temporal Predictability of Predation Risk: An Extension of the Risk Allocation Hypothesis

This study failed to show an effect of risk predictability on the behavioural responses of cichlids to high-risk alarm cues, but predictability did influence responses to low-risk cues, and encourages further studies to test the effect of predictability in other systems.

The paradox of risk allocation: a review and prospectus

Effects of temporal variation in the risk of predation by least weasel (Mustela nivalis) on feeding behavior of field vole (Microtus agrestis)

Feeding effort of field voles exposed to varying presence of least weasel and its feces in laboratory conditions indicated that feeding effort was lower in high risk situations than in low risk situations at high attack ratio, but not at a lower one.

Influences of divergent behavioral strategies upon risk allocation in juvenile flatfishes

Observations of unique anti-predator strategies, along with differences in foraging and species-specific ecologies, suggest divergent trajectories of risk allocation for the three species.



Temporal Variation in Danger Drives Antipredator Behavior: The Predation Risk Allocation Hypothesis

This analysis suggests that an animal should exhibit its greatest antipredator behavior in high‐risk situations that are brief and infrequent, and suggests that a common experimental protocol is likely to overestimate the intensity of antipredators behavior expected under field situations or chronic exposure to high risk.

Constrating short-term and long-term effects of predation risk on consumer habitat use and resources

It is suggested that the changing patterns of snail habitat use over time are consistent with the idea that snails balance predation risk against foraging gains when selecting habitats and that the manner in which they balance foraging gain and predationrisk determines the pattern of periphyton standing crops across habitats.

Effects of predatory risk and resource renewal on the timing of foraging activity in a gerbil community

It is demonstrated for the first time that gerbils responded to temporal and spatial heterogeneity in predatory risk through their timing of activity over the course of each night, and the dynamic nature of gerbil foraging decisions is shown, with animals altering foraging efforts in response to time, microhabital, moon phase, illumination, and resource availability.

Prey Uncertainty and the Balancing of Antipredator and Feeding Needs

Observations on the responses of juvenile aquatic bugs to the experimental addition and removal of cannibalistic adults showed that, as predicted by theory, prey behavioral time lags were longer when predator density was higher, prey were less hungry, and prey had lower escape ability.

Ecological Consequences of the Trade-Off between Growth and Mortality Rates Mediated by Foraging Activity

These models develop models predicting adaptive responses for both foraging speed and proportion of time active when individual growth rate and mortality risk are functions of these variables, particularly the role of activity responses in competitive interactions and indirect effects and patterns of coexistence among competitors.

The Dynamics of Prey Refuge Use: A Model and Tests with Sunfish and Salamander Larvae

A simple dynamic model of refuge use is developed that predicts patterns over time for prey survival and for the proportion of prey in refuge and the apparent paradox of a high predation rate when few prey are exposed could be easily understood only in terms of the dynamics of Refuge use.

Risk of predation and the structure of desert rodent communities

A correlation between auditory bullar volume and use of open habitat by the various species in this community suggests that predation risk provides an axis along which habitat segregation occurs, and can structure communities of mobile prey when risk differs among habitats.

The scent of death: Chemosensory assessment of predation risk by prey animals

This paper provides an exhaustive review of the literature on the responses of prey to predator chemosensory cues, primarily in tabular form, and highlights the most important studies on predator activity level and diet.

Predator-Avoidance Responses in Freshwater Decapod-Gastropod Interactions Mediated by Chemical Stimuli

None of the planorbids (Helisoma anceps or Gyraulus parvus) crawled out, even when young, in this study, apparently due to differences in selection pressures caused by differences in use of various microhabitats where risk of predation varies over time.
