Ecology and Evolution, 2020 The perception of predation risk could affect prey phenotype both within and between generations (via parental effects). The response to predation risk could involve modifications in physiology, morphology, and behavior and can ultimately affect long ...

Fungi, feather damage, and risk of predation [PDF]
Ecology and Evolution, 2017 AbstractPredation is a powerful selective force with important effects on behavior, morphology, life history, and evolution of prey. Parasites may change body condition, health status, and ability to escape from or defend prey against predators. Once a prey individual has been detected, it can rely on a diversity of means of escape from the pursuit by ...

Ungulate presence and predation risks reduce acorn predation by mice in dehesas
PLOS ONE, 2022 Foraging decisions by rodents are key for the long-term maintenance of oak populations in which avian seed dispersers are absent or inefficient. Decisions are determined by the environmental setting in which acorn-rodent encounters occur. In particular, seed value, competition and predation risks have been found to modify rodent foraging decisions in ...

The trade-off between starvation and predation risk in overwintering redshanks (Tringa totanus) [PDF]
, 2010 In order to meet their energy budget animals must often increase their risk of predation, either through their choice of foraging location or by decreasing anti-predation behaviours, which are incompatible with foraging.

Spatiotemporal Effects of Supplementary Feeding of Wild Boar (Sus scrofa) on Artificial Ground Nest Depredation. [PDF]
PLoS ONE, 2015 Supplementary feeding of ungulates, being widely used in game management, may have unwanted consequences. Its role in agricultural damage is well-studied, but few studies have considered the potential for the practice to attract ground nest predators ...

Compensatory human and predator risk trade-offs in neonatal white-tailed deer
Global Ecology and Conservation, 2022 Neonatal mortality is a primary determinant of ungulate population dynamics and occurs from multiple proximal causes, but few studies have compared relationships between risk factors and cause-specific mortality.

Ecology and Evolution, 2022 There is growing evidence that prey perceive the risk of predation and alter their behavior in response, resulting in changes in spatial distribution and potential fitness consequences.

Diel patterns of predation and fledging at nests of four species of grassland songbirds
Ecology and Evolution, 2021 Although it is common for nestlings to exhibit a strong bias for fledging in the morning, the mechanisms underlying this behavior are not well understood. Avoiding predation risk has been proposed as a likely mechanism by a number of researchers. We used

A multi-stage anti-predator response increases information on predation risk [PDF]
Journal of Experimental Biology, 2010 SUMMARYOptimal escape theory generally assumes that animals have accurate information about predator distance and direction of approach. To what degree such information is available depends not only on the prey's sensory capabilities but also on its behaviour.
