Prey‐driven behavioral habitat use in a low‐energy ambush predator
Ecology and Evolution, 2021 Food acquisition is an important modulator of animal behavior and habitat selection that can affect fitness. Optimal foraging theory predicts that predators should select habitat patches to maximize their foraging success and net energy gain, likely ...

Leaving safety to visit a feeding site: is it optimal to hesitate while exposed? [PDF]
Royal Society Open Science, 2017 Animals living in complex environments experience differing risks of predation depending upon their location within the landscape. An animal could reduce the risk it experiences by remaining in a refuge site, but it may need to emerge from its refuge and

Inversion of pheromone preference optimizes foraging in C. elegans
eLife, 2021 Foraging animals have to locate food sources that are usually patchily distributed and subject to competition. Deciding when to leave a food patch is challenging and requires the animal to integrate information about food availability with cues signaling

(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.

The effects of a competitor on the foraging behaviour of the shore crab Carcinus maenas. [PDF]
, 2014 Optimal Diet Theory suggests that individuals make foraging decisions that maximise net energy intake. Many studies provide qualitative support for this, but factors such as digestive constraints, learning, predation-risk and competition can influence ...

Biased Learning as a Simple Adaptive Foraging Mechanism
Frontiers in Ecology and Evolution, 2022 Adaptive cognitive biases, such as “optimism,” may have evolved as heuristic rules for computationally efficient decision-making, or as error-management tools when error payoff is asymmetrical.

Particle foraging strategies promote microbial diversity in marine environments
eLife, 2022 Microbial foraging in patchy environments, where resources are fragmented into particles or pockets embedded in a large matrix, plays a key role in natural environments. In the oceans and freshwater systems, particle-associated bacteria can interact with

Physical Review E, 2018 We introduce the \emph{frugal foraging} model in which a forager performs a discrete-time random walk on a lattice, where each site initially contains $\mathcal{S}$ food units. The forager metabolizes one unit of food at each step and starves to death when it last ate $\mathcal{S}$ steps in the past. Whenever the forager decides to eat, it consumes all
