Adaptation of Drosophila larva foraging in response to changes in food resources
eLife, 2022 All animals face the challenge of finding nutritious resources in a changing environment. To maximize lifetime fitness, the exploratory behavior has to be flexible, but which behavioral elements adapt and what triggers those changes remain elusive. Using

Foraging under conditions of short-term exploitative competition: The case of stock traders [PDF]
, 2013 Theory purports that animal foraging choices evolve to maximize returns, such as net energy intake. Empirical research in both human and nonhuman animals reveals that individuals often attend to the foraging choices of their competitors while making ...

Information foraging with an oracle
PLOS ONE, 2023 During ecological decisions, such as when foraging for food or selecting a weekend activity, we often have to balance the costs and benefits of exploiting known options versus exploring novel ones. Here, we ask how individuals address such cost-benefit tradeoffs during tasks in which we can either explore by ourselves or seek external advice from an ...

A small number of workers with specific personality traits perform tool use in ants
eLife, 2020 Ants use debris as tools to collect and transport liquid food to the nest. Previous studies showed that this behaviour is flexible whereby ants learn to use artificial material that is novel to them and select tools with optimal soaking properties ...

Shortening day length as a previously unrecognized selective pressure for early breeding in a bird with long parental care [PDF]
, 2014 Several different selective pressures have been suggested to explain an intense competition for early return to breeding grounds in birds. In this study we hypothesized that shortening day length during summer months may constitute additional ...

Research on Re-Searching: Interrupted Foraging is Not Disrupted Foraging
Cognitive Research: Principles and Implications, 2023 AbstractIn classic visual search, observers typically search for the presence of a target in a scene or display. In foraging tasks, there may be multiple targets in the same display (or “patch”). Observers typically search for and collect these target items in one patch until they decide to leave that patch and move to the next one.

Anticipatory Behavior of the Clonal Plant Fragaria vesca
Frontiers in Plant Science, 2018 Active foraging for patchy resources is a crucial feature of many clonal plant species. It has been recently shown that plants’ foraging for resources can be facilitated by anticipatory behavior via association of resource position with other ...

Energetic synchrony throughout the non‐breeding season in common guillemots from four colonies
Journal of Avian Biology, 2023 The non‐breeding season presents significant energetic challenges to birds that breed in temperate or polar regions, with clear implications for population dynamics.

Honeybee rebel workers invest less in risky foraging than normal workers [PDF]
, 2018 In eusocial insect colonies, workers have individual preferences for performing particular tasks. Previous research suggests that these preferences might be associated with worker reproductive potential; however, different studies have yielded ...

Frontiers in Psychology, 2015 Many contemporary concerns (e.g., addiction, failure to save) can be viewed as intertemporal choice problems in which the consequences of choices are realized at different times.
