Foraging Behavior and Subtask Hierarchical Structure in Acromyrmex spp. (Hymenoptera: Formicidae)
This study considers the function and complexity of tasks during foraging of three Acromyrmex species. Foraging was classified as a team task composed of 2 or 3 processes: recruitment, selection, and collection. Each process ...
Double purpose wheat: correlation analysis of forage yield components

Assessment of predation risk via illumination level: facultative central place foraging in the cricetid rodent Phyllotis darwini
It is well known that the risk of predation affects prey decision making. However, few studies have been concerned with the cues used by prey to assess this risk. Prey animals may use indirect environmental cues to assess ...
A breath of fresh air in foraging theory: The importance of wind for food size selection in a central-place forager
(University of Chicago Press, 2017-09)
Empirical data about food size carried by central-place foragers do not often fit with the optimum predicted by classical foraging theory. Traditionally, biotic constraints such as predation risk and competition have been ...
Iodine concentration in forages from dairy farms in the IXth and X-th Regions of Chile
(UNIV AUSTRAL CHILE. FAC CIENCIAS VETERINARIAS, 2003)
Influence of Abiotic Factors and Floral Resource Availability on Daily Foraging Activity of Bees
In this study, the daily and seasonal influences of abiotic factors and the amount of floral resources on the foraging frequency of bees were determined. The experiments were performed, during 12 consecutive months, in the ...
To exchange or not to exchange liquid food: is that the question for foraging leaf-cutting ant workers?
Leaf-cutting ants forage fresh plants in the field to cultivate the symbiotic fungus in their nests. The trophallaxis rates in leaf-cutting ants may be related to liquid foraging behavior and exchanging liquid food with ...
