Refuge or predation risk? Alternate ways to perceive hiker disturbance based on maternal state of female caribou

DOI: 10.1002/ece3.2672
Abstract: Abstract Human presence in natural environments is often a source of stress that is perceived by large ungulates as an increased risk of predation. Alternatively, disturbance induced by hikers creates a relatively predator‐free space that… read more here.

Indirect risk effects reduce feeding efficiency of ducks during spring

DOI: 10.1002/ece3.3714
Abstract: Abstract Indirect risk effects of predators on prey behavior can have more of an impact on prey populations than direct consumptive effects. Predation risk can elicit more vigilance behavior in prey, reducing the amount of… read more here.

Chronology of reproductive investment determines predation risk aversion in a felid‐ungulate system

DOI: 10.1002/ece3.4947
Abstract: Abstract Fear of predators can behaviorally mediate prey population dynamics, particularly when predation risk influences reproductive investment. However, the costs of reproductive investment may mitigate predation risk aversion relative to periods when the link between… read more here.

Semi‐intensive shrimp farms as experimental arenas for the study of predation risk from falcons to shorebirds

DOI: 10.1002/ece3.8059
Abstract: Abstract Varying environmental conditions and energetic demands can affect habitat use by predators and their prey. Anthropogenic habitats provide an opportunity to document both predation events and foraging activity by prey and therefore enable an… read more here.

Beyond the encounter: Predicting multi‐predator risk to elk (Cervus canadensis) in summer using predator scats

DOI: 10.1002/ece3.8589
Abstract: Abstract 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. Previous approaches to mapping predation risk across… read more here.

“Ecology of fear” in ungulates: Opportunities for improving conservation

DOI: 10.1002/ece3.8657
Abstract: Abstract Because ungulates are important contributors to ecosystem function, understanding the “ecology of fear” could be important to the conservation of ecosystems. Although studying ungulate ecology of fear is common, knowledge from ungulate systems is… read more here.

Camera trap data suggest uneven predation risk across vegetation types in a mixed farmland landscape

DOI: 10.1002/ece3.9027
Abstract: Abstract Ground‐nesting farmland birds such as the grey partridge (Perdix perdix) have been rapidly declining due to a combination of habitat loss, food shortage, and predation. Predator activity is the least understood factor, especially its… read more here.

DOI: 10.1002/ece3.9523
Abstract: Abstract Perceived predation risk varies in space and time. Foraging in this landscape of fear alters forager‐resource interactions via cascading nonconsumptive effects. Estimating these indirect effects is difficult in natural systems. Here, we applied a… read more here.

Seasonal fecundity and costs to λ are more strongly affected by direct than indirect predation effects across species.

DOI: 10.1002/ecy.1860
Abstract: Increased perceived predation risk can cause behavioral and physiological responses to reduce direct predation mortality, but these responses can also cause demographic costs through reduced reproductive output. Such indirect costs of predation risk have received… read more here.

DOI: 10.1002/ecy.3943
Abstract: Models mimicking prey organisms are increasingly used in ecological studies including testing fundamental ecological and evolutionary theories. The general consensus is that predation risk estimated on artificial models may not quantitatively correspond to predation pressure… read more here.

DOI: 10.1007/s00265-019-2668-x
Abstract: Predation and brood parasitism have critical effects on the fitness of animals, but few studies have focused on the potential interactions between these two important selective forces. For instance, the egg-rejection process, one of the… read more here.
