- 摘要：
- rease in feeding efficiency. We directly test the hypotheses that (1) there are reversible shifts in jaw length to test diameter ratios with food abundance in individual

- 摘要：
- primate species was estimated along gradients of elevation, food resource abundance, and anthropogenic habitat disturbance at local scales in southeast
Data from: Relative preference and localized food affect predator space use and consumption of incidental prey

- 摘要：
- highlight the contingent but predictable effects of locally abundant food on risk experienced by incidental prey, which can be positive or negative depending
Data from: Parallel declines in abundance of insects and insectivorous birds in Denmark over 22 years

Data from: High temperature intensifies negative density dependence of fitness in red flour beetles

- DOI：
- doi:10.5061/dryad.7fn80
- 摘要：
- negative density dependence in the number of eggs laid; this pattern was most evident when food was abundant. Density had no effect on development time, but low temperatures

- 摘要：
- presence of the top predator (a damselfly) had a strong cascading effect on the food web, propagating down to nutrient cycling. This predation risk cue ha
