- 摘要：
- onally, tool selection occurred at two stages: when tools were picked up and dropped into baits, and later, when food-soaked tools were retrieved from baits. Our result

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
