- 摘要：
- 1. The relative importance of bottom-up versus top-down control of population dynamics has been the focus of much debate. In infectious disease

- 摘要：
- an oviposition range expansion by the pollinator, with the use of a wider range of ovules that could otherwise have generated seeds. Loss of top-down control ha
Data from: Pulsing hydrology determines top-down control of basal resources in a tropical river-floodplain ecosystem

- 摘要：
- ting the relative influence of bottom-up and top-down processes in trophic networks. Many tropical floodplain rivers have sustained seasonal flood pulses driven

- 摘要：
- s underscore the importance of top-down control in community ecology, but show that its outcomes hinge on prey behavior, spatial structure, and omnivory

- 摘要：
- -based (top-down) nature. But, due to their complexity these effects are often considered separately and their relative strength, acting simultaneously
Data from: Environmental fluctuations restrict eco-evolutionary dynamics in predator-prey system

- 摘要：
- cifically, we followed population dynamics and a prey defence trait over time when populations were exposed to regular changes of bottom-up or top-down stressors, or combinations of these
Data from: Experiments reveal limited top-down control of key herbivores in southern California kelp forests
- 负责人：
- DOI：
- doi:10.5061/dryad.50t6sq6
- 摘要：
- in southern California where predatory sea otters have been extirpated, top-down control of sea urchins by alternative predators has been hypothesized but rarely tested
Data from: Trophic rewilding establishes a landscape of fear: Tasmanian devil introduction increases risk-sensitive foraging in a key prey species

- 摘要：
- and passive trophic rewilding have potentially begun restoring these lost top-down controls. The Tasmanian devil (Sarcophilus harrisii) has declined severely
