Goats favour personal over social information in an experimental foraging task [PDF]

, 2013
Animals can use their environments more efficiently by selecting particular sources of information (personal or social), according to specific situations.

Interactions between nutrients and fruit secondary metabolites shape bat foraging behavior and protein absorption

Ecosphere
Frugivore foraging behavior is largely influenced by two key groups of chemical traits: nutrients and secondary metabolites. Many secondary metabolites function in plant defense, but their consumption can negatively impact both mutualistic and ...

Overlap and temporal variation in the diets of sympatric Antarctic and Subantarctic fur seals (Arctocephalus spp.) at Marion Island, Prince Edward Islands

Polar Research, 2018
Antarctic (Arctocephalus gazella) and Subantarctic (A. tropicalis) fur seals are important predators in the Southern Ocean. Marion Island (southern Indian Ocean) hosts the largest sympatric breeding populations of these two species.

Diving behaviour of adult male white whales (Delphinapterus leucas) in Svalbard, Norway

Polar Research, 2019
White whales (Delphinapterus leucas) in Svalbard remain near the coast much of the year, spending most of their time in front of tidewater glaciers. In this article, the diving behaviour of adult male white whales in Svalbard (N = 16) is presented based ...

Foraging preferences of the threatened coastal California Gnatcatcher (Polioptila californica) during the non-breeding season

Journal of Field Ornithology, 2023
We studied the foraging behavior of the federally threatened coastal California Gnatcatcher (Polioptila californica), an obligate insectivore, during the non-breeding season, a period of reduced survivorship for this non-migratory passerine due to ...

On the Early Holocene: Foraging to Early Agriculture [PDF]

We consider a world in which the mode of food production, foraging or agriculture, is endogenous, and in which technology grows exogenously. Within a model of coalition formation, we allow individuals to rationally form cooperative communities (bands) of

Satisfying giant appetites : mechanisms of small scale foraging by large African herbivores [PDF]

, 2009
Variation in body mass allows for resource partitioning and co-existence of different species. Body mass is also seen as the main factor governing nutrient requirements in herbivores as metabolic rate and requirements have often been found to scale to ¾ ...
