Nutritional and environmental factors influence small mammal seed selection in a northern temperate forest

Ecosphere, 2022
Rodents can influence the succession and assembly of plant communities by preying on and dispersing seeds. Using a seed tray experiment with three common seeds, American beech (Fagus grandifolia), red maple (Acer rubrum), and eastern hemlock (Tsuga ...

Ecological Validity of Impulsive Choice: Consequences of Profitability-Based Short-Sighted Evaluation in the Producer-Scrounger Resource Competition

Frontiers in Applied Mathematics and Statistics, 2018
Results of intertemporal choice paradigm have been accounted for mostly by psychological terms such as temporal discounting of subjective value. Inability to wait for delayed gratification (choice impulsiveness, as opposed to self-control) is often taken

Linking movement and dive data to prey distribution models: new insights in foraging behaviour and potential pitfalls of movement analyses

Movement Ecology, 2023
Background Animal movement data are regularly used to infer foraging behaviour and relationships to environmental characteristics, often to help identify critical habitat.

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.

Memory Matters: Bumblebee Behavioral Models for Vehicle-to-Vehicle Communications

IEEE Access, 2018
Vehicles forming connected communication networks are routinely challenged with the complex decision problem of either staying with the same wireless channel or moving to a different wireless channel when experiencing highly variable channel quality ...

The glass is half-full: overestimating the quality of a novel environment is advantageous. [PDF]

PLoS ONE, 2012
According to optimal foraging theory, foraging decisions are based on the forager's current estimate of the quality of its environment. However, in a novel environment, a forager does not possess information regarding the quality of the environment, and ...

Insights for caribou/reindeer management using optimal foraging theory

Rangifer, 1991
Optimal foraging theory is useful to wildlife managers, because it helps explain the nutritional value of different habitats for wildlife species. Based upon nutritional value, the use of different habitats can be predicted, including how factors such as

Foraging conditions for breeding penguins improve with distance from colony and progression of the breeding season at the South Orkney Islands

Movement Ecology, 2021
Background According to central place foraging theory, animals will only increase the distance of their foraging trips if more distant prey patches offer better foraging opportunities.

CHOICE, CONTINGENCY DISCRIMINATION, AND FORAGING THEORY [PDF]

Journal of the Experimental Analysis of Behavior, 1999
Four pigeons were trained on eight or nine pairs of independent concurrent variable‐interval schedules. The range of reinforcement ratios included extreme ratios (up to 532 to 1). Large samples of stable performance were gathered. Contrary to the findings of Davison and Jones (1995), the generalized matching law described choice more accurately than a ...

Normative theory of patch foraging decisions [PDF]

bioRxiv, 2020
Foraging is a fundamental behavior as animals’ search for food is crucial for their survival. Patch leaving is a canonical foraging behavior, but classic theoretical conceptions of patch leaving decisions lack some key naturalistic details.
