- 负责人：
- Marino, John A.
- DOI：
- doi:10.5061/dryad.631j930
- 摘要：
- n infection load (number of cysts) in tadpoles in near-bottom cages was 83% higher after 48-hour exposures in the laboratory and 730% higher after 10-day
Data from: Negative effects of litter richness on root decomposition in the presence of detritivores
- 负责人：
- DOI：
- doi:10.5061/dryad.505d9
- 摘要：
- bottom-up effects from specific plant species and might affect microbial decomposer communities. 3. We found that the richness level of root litter mixtures di
Data from: Pollinator visitation rate and effectiveness vary with flowering phenology
- 负责人：
- DOI：
- doi:10.7280/D19X0D
- 摘要：
- over the season, countering the decrease in visitation rate so that flowering time had little net effect on seed set.

- DOI：
- doi:10.5061/dryad.v9s4mw6s6
- 摘要：
- metazoan parasites are detectable in fluid-preserved fish specimens when using visual parasite detection techniques.

- DOI：
- doi:10.5061/dryad.28032r2
- 摘要：
- Herbivore-plant interactions should be studied using a tri-trophic approach, but we lack a quantitative measure of the combined effect of top-down

- 负责人：
- DOI：
- doi:10.5061/dryad.rk64m4c
- 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

- 负责人：
- DOI：
- doi:10.5061/dryad.t446r
- 摘要：
- r larger spatial scales. Our results illustrate that small no-take zones can have bottom-up benefits for highly mobile marine predators, but are only one

- 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 population
Data from: Bottom-up regulation of parasite population densities in freshwater ecosystems
- 负责人：
- DOI：
- doi:10.5061/dryad.427v8
- 摘要：
- Theory predicts the bottom–up coupling of resource and consumer densities, and epidemiological models make the same prediction for host–parasite
