Reconciling Behavioural, Bioenergetic, and Oceanographic Views of Bowhead Whale Predation on Overwintering Copepods at an Arctic Hotspot (Disko Bay, Greenland)

open access: yesFrontiers in Marine Science, 2021
Bowhead whales (Balaena mysticetus) visit Disko Bay, West Greenland in winter and early spring to feed on Calanus spp., at a time of year when the copepods are still mostly in diapause and concentrated in near-bottom patches.

On Optimal Tempered Lévy Flight Foraging

open access: yesFrontiers in Physics, 2018
Optimal random foraging strategy has gained increasing concentrations. It is shown that Lévy flight is more efficient compared with the Brownian motion when the targets are sparse.

Foraging Behavior of Zonotrichia capensis (Passeriformes: Emberizidae) and Patch Value in Young Live Fences in the Bogotá High Plateau

open access: yesActa Biológica Colombiana, 2016
The Rufous-collared Sparrow Zonotrichia capensis is a widely distributed species in neotropical America, it is tolerant to human interventions, but we know little about its foraging ecology on the Colombian Andes.

Litter Surface Temperature: A Driving Factor Affecting Foraging Activity in Dinoponera lucida (Hymenoptera: Formicidae)

open access: yesSociobiology, 2021
Dinoponera lucida is a poneromorph ant endemic to the Atlantic Forest of Brazil. The species is classified as endangered in Brazil’s Red List due to its peculiar reproductive biology and high habitat fragmentation. Herein, we characterize D.

Adaptive Bacterial Foraging Optimization

open access: yesAbstract and Applied Analysis, 2011
Bacterial Foraging Optimization (BFO) is a recently developed nature‐inspired optimization algorithm, which is based on the foraging behavior ofE. colibacteria. Up to now, BFO has been applied successfully to some engineering problems due to its simplicity and ease of implementation.

Adaptive Lévy processes and area-restricted search in human foraging [PDF]

open access: yes, 2013
A considerable amount of research has claimed that animals’ foraging behaviors display movement lengths with power-law distributed tails, characteristic of Lévy flights and Lévy walks.

Contrasting Foraging Patterns: Testing Resource-Concentration and Dilution Effects with Pollinators and Seed Predators

open access: yesInsects, 2016
Resource concentration effects occur when high resource density patches attract and support more foragers than low density patches. In contrast, resource dilution effects can occur if high density patches support fewer consumers.

Eat or be eaten: Implications of potential exploitative competition between wolves and humans across predator‐savvy and predator‐naive deer populations

open access: yesEcology and Evolution, 2023
Recolonization of predators to their former ranges is becoming increasingly prevalent. Such recolonization places predators among their prey once again; the latter having lived without predation (from such predators) for a considerable time. This renewed

Optimal foraging in semantic memory. [PDF]

open access: yesPsychological Review, 2012
Do humans search in memory using dynamic local-to-global search strategies similar to those that animals use to forage between patches in space? If so, do their dynamic memory search policies correspond to optimal foraging strategies seen for spatial foraging?
