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

PLoS Biology, 2008 When voters in Washington State banned hound hunting with an eye to protecting cougars, they unwittingly triggered a chain of events that wildlife biologists are still trying to understand.

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

Intraguild predation and competition impacts on a subordinate predator [PDF]
Oecologia, 2016 Intraguild (IG) predation and interspecific competition may affect the settlement and success of species in their habitats. Using data on forest-dwelling hawks from Finland, we addressed the impact of an IG predator, the northern goshawk Accipiter gentilis (goshawk), on the breeding of an IG prey, the common buzzard Buteo buteo.

Interactions between different predator-prey states. A method for the derivation of the functional and numerical response [PDF]
2020, Journal of Mathematical Biology, 2019 In this paper we introduce a formal method for the derivation of a predator's functional response from a system of fast state transitions of the prey or predator on a time scale during which the total prey and predator densities remain constant. Such derivation permits an explicit interpretation of the structure and parameters of the functional ...

Ecology and Evolution, 2019 The enemy‐free space hypothesis (EFSH) contends that generalist predators select for dietary specialization in insect herbivores. At a community level, the EFSH predicts that dietary specialization reduces predation risk, and this pattern has been found ...

A two patch prey-predator model with multiple foraging strategies in predators: Applications to Insects [PDF]
arXiv, 2015 We propose and study a two patch Rosenzweig-MacArthur prey-predator model with immobile prey and predator using two dispersal strategies. The first dispersal strategy is driven by the prey-predator interaction strength, and the second dispersal is prompted by the local population density of predators which is referred as the passive dispersal.

Predator-prey dynamics pertaining to structuralizing predator species into three stages coupled with maturation delay owing to juvenile hunting [PDF]
arXiv, 2023 The predator-prey dynamic appertaining to two species is explored, wherein the predator species is structured into different stages. As evidenced from natural documentation, the immature predators possess the potential to predate albeit not as competently as the adults.

Journal of Animal Ecology, 2016 Predators can exert strong direct and indirect effects on ecological communities by intimidating their prey. The nature of predation risk effects is often context dependent, but in some ecosystems these contingencies are often overlooked.
