Density-dependent, central-place foraging in a grazing herbivore: competition and tradeoffs in time allocation near water [PDF]
, 2015 Optimal foraging theory addresses one of the core challenges of ecology: predicting the distribution and abundance of species. Tests of hypotheses of optimal foraging, however, often focus on a single conceptual model rather than drawing upon the ...

The Adaptive Significance of Flash Behavior: A Bayesian Model
Frontiers in Ecology and Evolution, 2022 Some cryptic animals have conspicuous color patches that are displayed when they move. This “flash behavior” may serve several functions, but perhaps the most widely invoked explanation is that the display makes it harder for the signaler to be found by ...

(Reinforcement?) Learning to forage optimally [PDF]
Current Opinion in Neurobiology, 2017 Foraging effectively is critical to the survival of all animals and this imperative is thought to have profoundly shaped brain evolution. Decisions made by foraging animals often approximate optimal strategies, but the learning and decision mechanisms generating these choices remain poorly understood.

Scaling of the risk landscape drives optimal life history strategies and the evolution of grazing [PDF]
, 2019 Consumers face numerous risks that can be minimized by incorporating different life-history strategies. How much and when a consumer adds to its energetic reserves or invests in reproduction are key behavioral and physiological adaptations that structure

Larval predation on different instars in blowfly populations
Brazilian Archives of Biology and Technology, 2004 During its larval stage, Chrysomya albiceps (Diptera: Calliphoridae) is a facultative predator on other blowflies. In this study, we evaluated the predation by third instar larvae of C.

Eating smart: Free-ranging dogs follow an optimal foraging strategy while scavenging in groups
Frontiers in Ecology and Evolution, 2023 Foraging and acquiring of food is a delicate balance between managing the costs (both energy and social) and individual preferences. Previous research on solitarily foraging free-ranging dogs showed that they prioritise the nutritionally highest valued ...

Tuning movement for sensing in an uncertain world
eLife, 2020 While animals track or search for targets, sensory organs make small unexplained movements on top of the primary task-related motions. While multiple theories for these movements exist—in that they support infotaxis, gain adaptation, spectral whitening ...

Phototaxic foraging of the archaepaddler, a hypothetical deep-sea species [PDF]
, 1998 An autonomous agent (animat, hypothetical animal), called the (archae) paddler, is simulated in sufficient detail to regard its simulated aquatic locomotion (paddling) as physically possible. The paddler is supposed to be a model of an animal that might
