Environmental constraints on the foraging behaviour, spatial usage and population sizes of albatrosses [PDF]

open access: yes, 2010
Satellite-tracking of wide-ranging, apex marine predators, combined with remote-sensing, can be used to test ecological hypotheses and to estimate spatial abundance.

Root Foraging Influences Plant Growth Responses to Earthworm Foraging [PDF]

open access: yes, 2014
Interactions among the foraging behaviours of co-occurring animal species can impact population and community dynamics; the consequences of interactions between plant and animal foraging behaviours have received less attention. In North American forests,

Does foraging success predict subsequent foraging behavior in Pygoscelis penguins?

open access: yes, 2023
Oliver, Matthew J.In a patchy prey environment, optimal foraging theory predicts that central place foragers will discretize horizontal movement and vertical movements into directed and resident foraging behaviors and that high foraging success should ...

Temporary Programs, Lasting Questions: Ad Hoc Assistance in the U.S. Farm Safety Net

open access: yesApplied Economic Perspectives and Policy, EarlyView.
ABSTRACT Large ad hoc assistance programs have returned to U.S. farm policy since 2017, operating alongside a more developed safety net built around federally subsidized crop insurance, Title I commodity programs, and standing disaster assistance. This paper reviews the renewed use of ad hoc assistance, documents its recent scale using USDA data, and ...

Nitrogen Isotopes Suggest Sex‐Based Diet Differences on the Breeding Grounds for a Sexually Monomorphic Migratory Passerine

open access: yesEcology and Evolution
Differential foraging by sex can have important implications for understanding the ecology of a species. This can be especially difficult to study through observations alone in sexually monomorphic species, such as the Golden‐crowned Sparrow (Zonotrichia

Foraging Connections: Optimal Foraging in Letter Fluency

open access: yes
The letter fluency task is the timed listing of words that begin with a specific letter (e.g., words starting with T). Participants often list words in phonologically related clusters (e.g., tank, task, tap) and occasionally switch clusters (e.g., tap, thud). This process has been likened to patch switching in animal foraging.

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.

Low Participation and Risk Reduction Potential of Supplemental Crop Insurance in the United States

open access: yesApplied Economic Perspectives and Policy, EarlyView.
ABSTRACT Federally subsidized crop insurance is a cornerstone of U.S. farm risk management, yet policies with the greatest share of participation only trigger indemnities after losses exceed 15%. Supplemental insurance was introduced to cover part of this deductible, but participation remains largely unchanged.

The importance of termites (Isoptera) for the recycling of herbivore dung in tropical ecosystems: a review

open access: yesEuropean Journal of Entomology, 2008
While the key role of termites in the decomposition of litter in the tropics has been acknowledged for a long time, much less information exists on their importance in the recycling of dung of primary consumers, especially herbivores.

Adaptive Bacterial Foraging Optimization Algorithm with Social Foraging Strategy for Multi-modal optimization problem

open access: yes, 2014
In 2002,K.M.Passino proposed Bacterial Foraging Optimization Algorithm(BFOA) for distributed optimization and control.Biologic foraging strategies are diverse.Based on social and intelligent foraging theory,this paper proposed an adaptive bacterial ...
