- 摘要：
- and bottom-up effects, is not static, but rather shifts markedly under different conditions. Climate thus has the potential to alter the strength and spatial dynamics
Data from: Consumer versus resource control and the importance of habitat heterogeneity for estuarine bivalves
- 负责人：
- DOI：
- doi:10.5061/dryad.4ht86
- 摘要：
- The relative influence of consumers (top down) and resources (bottom up) on the distribution and abundance of organisms remains a key question
Data from: Linking songbird nest predation to seedling density: sugar maple masting as a resource pulse in a forest food web
- 负责人：
- DOI：
- doi:10.5061/dryad.708b0
- 摘要：
- , bottom-up forces often exert a strong influence on ecosystem functioning. Here, we report on the indirect influence of a pulsed resource, sugar maple (Acer saccharum
Data from: Opposing effects of mortality factors on progeny operational sex ratio may thwart adaptive manipulation of primary sex ratio
- 负责人：
- DOI：
- doi:10.5061/dryad.4c058
- 摘要：
- work has indicated that reduced host plant foliage quality induces female-biased mortality in this species, bottom-up and top-down factors act
Data from: Biocontrol: the response of native oystercatchers to a non-native clam invasion
- 负责人：
- DOI：
- doi:10.5061/dryad.b8f0vg0
- 摘要：
- Global change, including invasive species introduction, has already had observable effects on migrant bird species, from Northern breeding area
Data from: Exploiting Poisson additivity to predict fire frequency from maps of fire weather and land cover in boreal forests of Québec, Canada
- 负责人：
- DOI：
- doi:10.5061/dryad.3rf1k
- 摘要：
- and weather conditions may influence fire regimes. We modelled the effects of bottom-up variables (e.g. land cover) and top-down variables (e.g. fire weather
Data from: Spatial transitions in tree cover are associated with soil hydrology, but not with grass biomass, fire frequency, or herbivore biomass in Serengeti savannahs
- 负责人：
- DOI：
- doi:10.5061/dryad.2280gb5n1
- 摘要：
- and tree cover is important for resolving the relative contribution of bottom-up vs. top-down factors in structuring savannah vegetation. 2. We quantified
Data from: Environmental context shapes the long?term role of nutrients in driving producer community trajectories in a top?down dominated
- 负责人：
- DOI：
- doi:10.5068/D14671
- 摘要：
- osystems, nutrient enrichment and the removal of consumers, are predicted to interact in their effects on producer diversity. Yet, measures of diversity alone may not capture cha
