Behavioural adjustment in response to increased predation risk: a study in three duck species. [PDF]

open access: yesPLoS ONE, 2011
Predation directly triggers behavioural decisions designed to increase immediate survival. However, these behavioural modifications can have long term costs. There is therefore a trade-off between antipredator behaviours and other activities.

A nutritionally-explicit test of the food-safety trade-off under predation risk [PDF]

open access: yesScientific Reports
Predation risk elicits physiological and behavioural responses that enhance prey survival but can constrain foraging. Extensive evidence suggests that prey experience a food-safety trade-off whereby prioritizing safety reduces resource acquisition ...

Behavioral trade‐offs and multitasking by elk in relation to predation risk from Mexican gray wolves [PDF]

open access: yesEcology and Evolution
Predator non‐consumptive effects (NCE) can alter prey foraging time and habitat use, potentially reducing fitness. Prey can mitigate NCEs by increasing vigilance, chewing‐vigilance synchronization, and spatiotemporal avoidance of predators. We quantified

Livestock guardian dogs create safer landscapes for sheep by reducing fox predation risk attributes [PDF]

open access: yesScientific Reports
Livestock predation by carnivores drives global human-carnivore conflict. Non-lethal strategies like Livestock Guardian Dogs (LGDs) prove effective, yet their interactions with biophysical factors (e.g., habitats) and ecological variables (e.g ...

Predation Risk Effects of Harmonia axyridis on the Development and Fecundity of Periphyllus koelreuteriae [PDF]

open access: yesInsects
In the scenario that requires the biological control of pests using predatory enemies, predators not only prey on pests directly but also can affect the population fitness of pests through indirect non-consumptive effects (predation risk effects ...

Predation risk and floral rewards: How pollinators balance these conflicts and the consequences on plant fitness [PDF]

open access: yesCurrent Research in Insect Science
Foraging behavior of pollinators is shaped by, among other factors, the conflict between maximizing resource intake and minimizing predation risk; yet, empirical studies quantifying variation in both forces are rare, compared to those investigating each ...

The importance of predator behaviour on risk to prey [PDF]

open access: yes, 2008
Both predator and prey have evolved to maximise reproductive success by balancing food intake with risk. There has been a bias in predator-prey studies, where prey behaviour has been examined in detail, yet predators are assumed to follow simplistic ...

Nociceptive Sensitization Reduces Predation Risk [PDF]

open access: yesCurrent Biology, 2014
Sublethal injury triggers long-lasting sensitization of defensive responses in most species examined, suggesting the involvement of powerful evolutionary selection pressures [1]. In humans, this persistent nociceptive sensitization is often accompanied by heightened sensations of pain and anxiety [2].

The increased risk of predation enhances cooperation [PDF]

open access: yesProceedings of the Royal Society B: Biological Sciences, 2009
Theory predicts that animals in adverse conditions can decrease individual risks and increase long-term benefits by cooperating with neighbours. However, some empirical studies suggest that animals often focus on short-term benefits, which can reduce the likelihood that they will cooperate with others.

Predation risk, elk, and aspen: comment [PDF]

open access: yesEcology, 2014
With the exception of humans, gray wolves (Canis lupus) are perhaps the most significant predator of cervids in the northern hemisphere, mainly due to the group-hunting, year-round activity, and widespread geographic distribution (Peterson et al. 2003).
