- 摘要：
- Can variation in prey density drive changes in the intensity or direction of selective predation in natural systems? Despite ample evidence of

- 摘要：
- Selecting the right habitat in a risky landscape is crucial for an individual's survival and reproduction. In predator–prey systems, prey oft

- 摘要：
- . Negative frequency-dependent selection by predators using search images (‘apostatic selection’) is often suggested without rejecting alternative explanations. Using a maximum likelihood appr
Data from: Predators weaken prey intraspecific competition through phenotypic selection

- 摘要：
- rhaps the most obvious way this occurs is when predators reduce competitor densities. However, consumption could also generate phenotypic selection on prey tha
