Sympatry Increases Predation Risk for an Endangered Ungulate [PDF]

open access: yesEcology and Evolution
Predation risk for depleted prey populations is known to be influenced by prey abundance. However, predation risk may also be influenced by the abundance of sympatric prey species, particularly when the sympatric species is abundant.

An Enclosed Nest Can Increase the Risk of Predation on Adults [PDF]

open access: yesEcology and Evolution
Even though enclosed nests provide a physical barrier for cavity‐nesting birds, nest predation is the primary cause of breeding failure and a major driver of avian population dynamics.

The trade-off between starvation and predation risk in overwintering redshanks (Tringa totanus) [PDF]

open access: yes, 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.

Reciprocal intraguild predation and predator coexistence [PDF]

open access: yesEcology and Evolution, 2018
AbstractIntraguild predation is a mix of competition and predation and occurs when one species feeds on another species that uses similar resources. Theory predicts that intraguild predation hampers coexistence of species involved, but it is common in nature.

Predators avoiding predation [PDF]

open access: yesProceedings of the National Academy of Sciences, 2008
The notion of stealthy predation often invokes images of a predator hiding and waiting to ambush its unsuspecting prey. In this issue of PNAS, Manicom et al. (1) offer an alternative reason why predators hide that involves an important tradeoff between capturing prey and seeking refuge to avoid their own demise from other predator species.

UNSUCCESSFUL PREDATION AND LEARNING OF PREDATOR CUES BY CRAYFISH [PDF]

open access: yesJournal of Crustacean Biology, 2003
Abstract The effect of latent inhibition on learning about cues related to increased predation risk was studied in a native crayfish, Orconectes virilis, and in an invasive species, Orconectes rusticus. Individuals of both species either were exposed or not exposed to the conditioned stimulus (potential “predator” odor = goldfish odor) prior to ...

High trees increase sunflower seed predation by birds in an agricultural landscape of Israel

open access: yesFrontiers in Ecology and Evolution, 2014
Natural habitats in agricultural landscapes promote agro-ecosystem services but little is known about negative effects (dis-services) derived by natural habitats such as crop seed predation.

Generalist predators disrupt parasitoid aphid control by direct and coincidental intraguild predation [PDF]

open access: yes, 2011
Generalist predators and parasitoids are considered to be important regulators of aphids. The former not only feed on these pests, but might also consume parasitoids at all stages of development.

Coping with shifting nest predation refuges by European reed Warblers Acrocephalus scirpaceus. [PDF]

open access: yesPLoS ONE, 2014
Predation, the most important source of nest mortality in altricial birds, has been a subject of numerous studies during past decades. However, the temporal dynamics between changing predation pressures and parental responses remain poorly understood. We
