Data from: Optimal foraging or surplus killing: selective consumption and discarding of salmon by brown bears
- 负责人：
- Lincoln, Alexandra
- DOI：
- doi:10.5061/dryad.3fg5r56
- 摘要：
- Selective consumption of prey by predators, observed in many animals, is often attributed to optimal foraging. Consistent with this idea, brown bears
Data from: Getting older, getting smarter: ontogeny of the foraging behaviour in the tropical social wasp Ropalidia marginata

- Foraging strategy Spatial learning and memory Tropical wasp Social Hymenoptera Behavioural ecology
- DOI：
- doi:10.5061/dryad.v116vr8
- 摘要：
- could be an optimal strategy for individually foraging animals inhabiting feature-rich landscapes.
Data from: What seeds tell us about birds: a multi-year analysis of acorn woodpecker foraging movements

- DOI：
- doi:10.5061/dryad.64jk6
- 摘要：
- was to test the optimal foraging theory prediction that territorial acorn woodpeckers (Melanerpes formicivorus) should forage closer to their 'central

- DOI：
- doi:10.5061/dryad.743g3
- 摘要：
- ng errors was higher. In summary, bees are able to use social and personal information to optimize foraging decisions in a flexible way.
Data from: Bottom time does not always predict prey encounter rate in Antarctic fur seals
- 负责人：
- DOI：
- doi:10.5061/dryad.ct511
- 摘要：
- Optimal foraging models applied to breath-holding divers predict that diving predators should optimize the time spent foraging at the bottom of dives
Data from: Discrimination behavior mediates foraging quality versus quantity trade-offs: nut choice in wild rodents
- 负责人：

- optimal foraging strategy;seed\/nut choice;food quality;food quantity;discrimination ability;Rodents
- DOI：
- doi:10.5061/dryad.8565n
- 摘要：
- Discrimination, the ability to distinguish sensory stimuli and respond accordingly, is a critical factor underscoring optimal foraging decisions. Ne
Data from: Integrating vital rates explains optimal worker size for resource return by bumble bee workers
- 负责人：
- DOI：
- doi:10.5061/dryad.42gp897
- 摘要：
- about optimal body size from being large to being near the observed average. Similar approaches of integrating multiple vital rates may resolve apparent
Data from: Optimal foraging by herbivores maintains polymorphism in defence in a natural plant population
- 负责人：
- Sato, Yasuhiro
- DOI：
- doi:10.5061/dryad.pn088
- 摘要：
- 1. Many species of plants and animals exhibit polymorphism for defensive traits. Adaptive foraging by natural enemies has long been hypothesized
Data from: Environmental heterogeneity decreases reproductive success via effects on foraging behaviour

- 关键词：
- Competition Seabird Hidden Markov Model Heterogeneity Gradient Optimal foraging theory Resource availability
- DOI：
- doi:10.5061/dryad.0898ss6
- 摘要：
- Environmental heterogeneity shapes the uneven distribution of resources available to foragers, and is ubiquitous in nature. Optimal foraging
Data from: Drosophila melanogaster larvae make nutritional choices that minimize developmental time
- 负责人：
- DOI：
- doi:10.5061/dryad.47880
- 摘要：
- t were suboptimal for all larval life history traits. Our results demonstrate that D. melanogaster larvae make foraging decisions that tra
