Analysis of adaptive foraging in an intraguild predation system [PDF]

open access: yesWeb Ecology, 2003
An intraguild predation (IGP) system with adaptive foraging behavior was analyzed using a simple mathematical model. The main aim was to explore how the adaptive behavior affects species interactions as well as how such interactions derived from ...

Effect of conspecific neighbors on the foraging activity levels of the wintering Oriental Storks (Ciconia boyciana): Benefits of social information

open access: yesEcology and Evolution, 2020
Animals prefer to aggregate in patches with high abundance and availability of food resources. Group foragers typically receive information about food resources by monitoring external events and the behavior of neighbors.

Down-regulation of honey bee IRS gene biases behavior toward food rich in protein. [PDF]

open access: yesPLoS Genetics, 2010
Food choice and eating behavior affect health and longevity. Large-scale research efforts aim to understand the molecular and social/behavioral mechanisms of energy homeostasis, body weight, and food intake.

Cognitive Aging and Adaptive Foraging Behavior [PDF]

open access: yesThe Journals of Gerontology Series B: Psychological Sciences and Social Sciences, 2009
We conducted two experiments comparing younger and older adults' ability to adjust their foraging behavior as a function of task characteristics. Participants foraged for fish in a virtual landscape and had to decide when to move between ponds so as to maximize the number of fish caught. In the first experiment, participants were left to generate their

Nocturnal Foraging by Red-Legged Kittiwakes, a Surface Feeding Seabird That Relies on Deep Water Prey During Reproduction. [PDF]

open access: yesPLoS ONE, 2015
Narrow foraging specialization may increase the vulnerability of marine predators to climate change. The red-legged kittiwake (Rissa brevirostris) is endemic to the Bering Sea and has experienced drastic population fluctuations in recent decades ...

Sheep in Species-Rich Temperate Grassland: Combining Behavioral Observations with Vegetation Characterization

open access: yesAnimals, 2020
Foraging behavior of livestock in species-rich, less intensively managed grassland communities will require different methodologies from those appropriate in floristically simple environments.

Behavior, size, and body condition predict susceptibility to management and reflect post-treatment frequency shifts in an invasive snake

open access: yesGlobal Ecology and Conservation, 2020
Foraging behavior can have population-level effects that are of interest for wildlife management. For invasive species, foraging behavior has been tied to establishment ability and rate of spread and is generally of import in understanding invasion ...

Variability in the Foraging Distribution and Diet of Cape Gannets between the Guard and Post-guard Phases of the Breeding Cycle

open access: yesFrontiers in Marine Science, 2018
During breeding, seabirds are central place foragers and are sensitive to changes in local prey availability. As the breeding season progresses, foraging behavior and distribution is expected to change in response to possible changes in local prey ...

Game-theoretic methods for functional response and optimal foraging behavior.

open access: yesPLoS ONE, 2014
We develop a decision tree based game-theoretical approach for constructing functional responses in multi-prey/multi-patch environments and for finding the corresponding optimal foraging strategies.

Hunting by the Stroke: How Foraging Drives Diving Behavior and Locomotion of East-Greenland Narwhals (Monodon monoceros)

open access: yesFrontiers in Marine Science, 2021
Deep diving air-breathing species by necessity must balance submergence time and level of exercise during breath-holding: a low activity level preserves oxygen stores and allows longer duration submergence whereas high activity levels consume oxygen ...
