Data from: Group foraging increases foraging efficiency in a piscivorous diver, the African penguin
- 负责人：
- McInnes, Alistair
- DOI：
- doi:10.5061/dryad.3j2q3
- 摘要：
- Marine piscivores have evolved a variety of morphological and behavioural adaptations, including group foraging, to optimize foraging
Data from: The evolution of foraging rate across local and geographic gradients in predation risk and competition
- 负责人：
- DOI：
- doi:10.5061/dryad.222h3
- 摘要：
- on, time constraints, and temperature. We tested six hypotheses for the evolution of foraging rate in 24 spotted salamander (Ambystoma maculatum) populations from thr

- 负责人：
- DOI：
- doi:10.5061/dryad.1gj36nn
- 摘要：
- 1. Optimal foraging theory predicts that animals will seek simultaneously to minimize food processing time and maximize energetic gain. Overal

- DOI：
- doi:10.5061/dryad.1b8m917
- 摘要：
- ow that when the environment is variable and foraging is reduced in bad years, the benefit of adopting an optimal strategy that includes reproducti
Data from: Gliding for a free lunch: biomechanics of foraging flight in Common Swifts (Apus apus)
- 负责人：
- DOI：
- doi:10.5061/dryad.89b2c4s
- 摘要：
- , the birds adjust their air speed to optimize cost of transport over distance. Finally, swifts spent only 25% of their time flapping; the majority of time (71

Data from: Pulsed resource availability changes dietary niche breadth and partitioning between generalist rodent consumers
- 负责人：
- DOI：

- 摘要：
- niches of consumers. We used natural pulses of mast-fruiting of American beech (Fagus grandifolia) to test whether optimal foraging or competiti
Data from: State dependence, personality, and plants: light-foraging decisions in Mimosa pudica (L.)
- 负责人：
- DOI：
- doi:10.5061/dryad.8852k
- 摘要：
- a “personality” (i.e., behavioral syndrome). We found that when individuals are in a low-energy state, they adopt a riskier light-foraging strategy, openi
Data from: Tidal drift removes the need for area restricted search in foraging Atlantic puffins
- 负责人：
- Jessopp, Mark
- DOI：
- doi:10.5061/dryad.8gj8kc3
- 摘要：
- ensures maximum prey encounter rate, but when prey is patchy, the optimal strategy resembles a Lévy walk where Area Restricted Search (ARS) is interspersed
Data from: Density-dependent, central-place foraging in a grazing herbivore: competition and trade-offs in time allocation near water
- 负责人：
- DOI：
- doi:10.5061/dryad.rb3jp
- 摘要：
- Optimal foraging theory addresses one of the core challenges of ecology: predicting the distribution and abundance of species. Tests of hypotheses
