Data from: Seasonal shifts in the importance of bottom-up and top-down factors on stream periphyton community structure
- 负责人：
- DOI：
- doi:10.5061/dryad.q436v45
- 摘要：
- We examined the importance of temporal variability in top-down and bottom-up effects on the accumulation of stream periphyton, which are complex

- 摘要：
- 1. Cascading effects in ecological systems acting across three or more trophic levels can be either of a resource-based (bottom-up) or natural enemy
Data from: The fluctuating world of a tundra predator guild: bottom-up constraints overrule top-down species interactions in winter

- 摘要：
- r bottom-up effects in Scandinavian mountain tundra (Northern Sweden) where effects of climate warming have been observed and top-down interactions are expect

- DOI：
- doi:10.5061/dryad.s0d20
- 摘要：
- Top-down processes, via the direct and indirect effects of interspecific competitive killing (no consumption of the kill) or intraguild predation
Data from: Combined bottom-up and top-down pressures drive catastrophic population declines of Arctic skuas in Scotland

- 摘要：
- was to determine relative effects of bottom-up and top-down pressures on Arctic skuas across multiple colonies in a rapidly declining national pop
Data from: Manipulating the system: how large herbivores control bottom-up regulation of grasslands
- 负责人：
- DOI：

- 摘要：
- s indicate the mechanistic linkage between top-down (herbivore) and bottom-up (soil resource) control of grassland production. Changing the resources tha
Data from: Warming advances top-down control and reduces producer biomass in a freshwater plankton community

- DOI：
- doi:10.5061/dryad.6tv0f
- 摘要：
- will not only depend on direct species-specific temperature effects, but also on indirect effects related to bottom-up and top-down processes. Here, we investigated
Data from: Trophic cascades in the bryosphere: The impact of global change factors on top-down control of cyanobacterial N2-fixation

- DOI：
- doi:10.5061/dryad.66d5f
- 摘要：
- r, organisms of higher trophic levels alleviated this top-down control, likely through feeding on bacterivorous microfauna. These effects of food web struct
Data from: Pulsing hydrology determines top-down control of basal resources in a tropical river-floodplain ecosystem

- DOI：
- doi:10.5061/dryad.f4211
- 摘要：
- -area densities of aquatic organisms. Therefore, one would predict that the strength of top-down effects of animals on basal resources should shift

- 负责人：
- DOI：
- doi:10.5061/dryad.0145sn6
- 摘要：
- t the habitat heterogeneity of seascapes can overwhelm the effects of conventional top-down and bottom-up structuring of herbivory on coral reefs.
