Data from: Disentangling ecologically equivalent from neutral species: the mechanisms of population regulation matter

- 摘要：
- to its density-dependent effects on every other guild member. In contrast, if each guild member directly limits itself more than it limits the abundance of other guild members, al
Data from: Predation and nutrients drive population declines in breeding waders

- 摘要：
- e consistent with the hypothesis that predation may reduce population density through negative density-dependence, while total nitrogen at adjacent shallow water
Data from: Condition-dependent movement and dispersal in experimental metacommunities

- doi:10.5061/dryad.nj957
- 摘要：
- dynamics. Generally, dispersal decisions are condition-dependent and rely on information in the broad sense, like the presence of conspecifics. However, studies
Data from: Negative frequency-dependent foraging behaviour in a generalist herbivore (Alces alces) and its stabilizing influence on food-web dynamics

- 摘要：
- resources. Frequency‐dependent foraging was further mediated by density‐dependent processes, which are likely to be predation, moose abundance, or som
Data from: Quantifying predator dependence in the functional response of generalist predators
- 负责人：
- DOI：
- doi:10.5061/dryad.sj94k
- 摘要：
- A long-standing debate concerns how functional responses are best described. Theory suggests that ratio dependence is consistent with many food web
Data from: Pre-dispersal context and presence of opposite sex modulate density dependence and sex bias of dispersal
- 负责人：
- DOI：
- doi:10.5061/dryad.7q18vk6
- 摘要：
- eover, we found that patterns of both density dependence and sex bias were contingent upon the interaction of males and females, as neither sex exhibited
Data from: Density-dependent, central-place foraging in a grazing herbivore: competition and trade-offs in time allocation near water
- 负责人：
- DOI：
- doi:10.5061/dryad.rb3jp
- 摘要：
- owed very strong density-dependence in how habitat could be selected. Knowledge of more than one theoretical framework may be required to explain observed
Data from: Private land conservation has landscape-scale benefits for wildlife in agroecosystems
