Cercarial Behavior Determines Risk of Predation
Journal of Parasitology, 2019The potential for local biodiversity to affect transmission success of parasites has been shown to be particularly important in trematodes, where non-host organisms can feed on and 'dilute' free-living infective stages (cercariae). Earlier studies have analyzed the effects of various predators on transmission stages of single trematode species, but not

Predation risk as a cost of reproduction
Trends in Ecology & Evolution, 1991Predation risk as a cost of reproduction in animals has recently received increased empirical and theoretical attention. Higher risk may be associated with all stages of reproduction. Examples of evolutionary responses to this increased risk include habitat choice, duration and timing of display and copulation, changes in brightness of breeding ...

Higher nest predation risk in association with a top predator: mesopredator attraction?
Oecologia, 2012Breeding close to top predators is a widespread reproductive strategy. Breeding animals may gain indirect benefits if proximity to top predators results in a reduction of predation due to suppression of mesopredators. We tested if passerine birds gain protection from mesopredators by nesting within territories of a top predator, the Ural owl (Strix ...

Perceived predation risk as a function of predator dietary cues in terrestrial salamanders
Animal Behaviour, 1999Prey often avoid predator chemical cues, and in aquatic systems, prey may even appraise predation risk via cues associated with the predator's diet. However, this relationship has not been shown for terrestrial predator-prey systems, where the proximity of predators and prey, and the intensity of predator chemical cues in the environment, may be less ...

Behavioral Ecology and Sociobiology, 2014
Previous studies indicate that when predation risk is uniform across habitats, foragers concentrate their exploitation in fewer patches. Although uniform predation risk may seem rare in nature, some scenarios might cause it. Testing all scenarios in a single experiment is unfeasible; therefore, we developed a model that points whether concentration of ...

Direction of Predator Turning, a Neglected Cue to Predation Risk
Behaviour, 1998AbstractAssessed risk for prey should depend not only on distance from a predator, but also on probability that it has been detected. If an indirectly approaching predator close enough to pose a threat suddenly turns toward prey, risk increases because the joint probability that the predator has detected and will attack is raised abruptly.

Sleeping under the risk of predation
Animal Behaviour, 2005Every studied animal engages in sleep, and many animals spend much of their lives in this vulnerable behavioural state. We believe that an explicit description of this vulnerability will provide many insights into both the function and architecture (or organization) of sleep.

Hamsters Use Predator Odors as Indirect Cues of Predation Risk
Ethology, 2010AbstractGolden hamsters (Mesocricetus auratus) use olfactory cues to assess traits of conspecifics such as kinship, individual identity, and reproductive status. The environment, however, is full of a wide variety of other olfactory information such as signals emitted by some of the hamster’s primary predators. Given this, we hypothesized that hamsters

Predation Risk of Pollinators on Flowers
Bee World, 2015Pollinators perform vital ecosystem services and have mutualistic relationships with flowering plants which coevolved over centuries of natural selection. During the process of foraging, they are vulnerable to several predators which eventually cause the ecosystem to suffer from low pollination services, loss of plant diversity and poor or reduced seed
