Children's competition in a natural setting: evidence for the ideal free distribution [PDF]

, 2011
Article in pressLittle is known of the foraging abilities of children in modern cultures, especially when children forage in groups. Here we present a test of optimal foraging theory in groups of street children working for money.

Beyond Depression? A Review of the Optimal Foraging Theory Literature in Zooarchaeology and Archaeobotany

Ethnobiology Letters, 2017
The use of optimal foraging theory in archaeology has been criticized for focusing heavily on “negative” human-environmental interactions, particularly anthropogenic resource depression, in which prey populations are reduced by foragers’ own foraging ...

Optimal Forager Against Ideal Free Distributed Prey [PDF]

, 2015
The introduced dispersal-foraging game is a combination of prey habi2 tat selection among two patch types and optimal foraging approaches. Prey’s patch 3 preference and forager behavior determine the prey’s survival rate.

Test of theory of foraging mode: Goldcrests, Regulus regulus, forage by high‐yield, energy‐expensive hovering flight when food is abundant but use low‐yield, low‐cost methods when food is scarce

Ecology and Evolution, 2021
Here, I describe foraging behavior of goldcrests, Regulus regulus, based on eight years of field observation in a coniferous forest dominated by Norway spruce Picea abies in southwestern Sweden.

Feeding ecology of a highly aerial bird during its long breeding season

Avian Research, 2023
Pallid Swifts (Apus pallidus), as other swifts, are birds extremely adapted to an aerial lifestyle, showing unique adaptations that allow them to fly almost continuously.

Creative foraging: An experimental paradigm for studying exploration and discovery. [PDF]

PLoS ONE, 2017
Creative exploration is central to science, art and cognitive development. However, research on creative exploration is limited by a lack of high-resolution automated paradigms.

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
