Prey body size mediates the predation risk associated with being "odd" [PDF]

open access: yes, 2014
Despite selection pressures on prey animals to maintain phenotypically homogeneous groups, variation in phenotype within animal groups is commonly observed.

(Reinforcement?) Learning to forage optimally [PDF]

open access: yesCurrent 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 Adaptive Significance of Flash Behavior: A Bayesian Model

open access: yesFrontiers 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 ...

Larval predation on different instars in blowfly populations

open access: yesBrazilian 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.

The effects of dominance on leadership and energetic gain: a dynamic game between pairs of social foragers [PDF]

open access: yes, 2011
Although social behaviour can bring many benefits to an individual, there are also costs that may be incurred whenever the members of a social group interact.

Non-L\'evy mobility patterns of Mexican Me'Phaa peasants searching for fuelwood [PDF]

open access: yes, 2012
We measured mobility patterns that describe walking trajectories of individual Me'Phaa peasants searching and collecting fuelwood in the forests of "La Monta\~na de Guerrero" in Mexico.

Optimal foraging or surplus killing: selective consumption and discarding of salmon by brown bears

open access: yesBehavioral Ecology, 2018
&NA; Selective consumption of prey by predators, observed in many animals, is often attributed to optimal foraging. Consistent with this idea, brown bears (Ursus arctos) often exhibit partial consumption, feeding exclusively on lipid‐rich tissues of ...

Tuning movement for sensing in an uncertain world

open access: yeseLife, 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 ...
