Data from: Effects of prey quality and predator body size on prey DNA detection success in a centipede predator
- 负责人:
- DOI:
- doi:10.5061/dryad.ss17b
- 摘要:
- Predator body size and prey quality are important factors driving prey choice and consumption rates. Both factors might affect prey detection succe
Data from: Phenological mismatch and ontogenetic diet shifts interactively affect offspring condition in a passerine

- DOI:
- doi:10.5061/dryad.5p65q
- 摘要:
- indirect effects of mismatch on fitness are well described, direct effects on parental prey choice are not. Moreover, direct effects of prey variation on offspr
Data from: Behavioural responses vary with prey species in the social spider, Stegodyphus sarasinorum

- doi:10.5061/dryad.r39mq1q
- 摘要:
- participation in prey capture have largely employed only one prey species, offering the predator no choice. In nature, predators encounter a range of prey species
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:
- r, bears also kill and abandon salmon without consuming any tissue. These discarded fish may be consistent with optimal foraging choices if they are of poor

- 摘要:
- while mesocarnivores (medium-sized mammalian predators) are increasing in number and ecological influence. Predator choice of prey is not random and different pr
Data from: Sex-specific prey partitioning in breeding piscivorous birds examined via a novel, non-invasive approach

- 摘要:
- foraging in inland waters is missing. Here, we assess sex-specific prey choice of Great Cormorants (Phalacrocorax carbo) during two subsequent
Data from: Digestive capacity and toxicity cause mixed diets in red knots that maximize energy intake rate
- 负责人:
- DOI:
- doi:10.5061/dryad.5fp4g
- 摘要:
- In energy-maximizing animals, preferences for different prey can be explained by ranking them by their energetic content. However, diet choice als

- 摘要:
- . Livestock predation, however, could either reduce or intensify with increases in wild prey depending on prey choice and trends in carnivore abundance. We show tha
