- ted with population density. The proportion of self-massulae deposition was three times higher in sparse patches compared to dense ones (41% vs. 14%). 5. Combined effects
Data from: Predation and nutrients drive population declines in breeding waders

- 摘要：
- Allee effects are defined as a decline in per capita fitness at low population density. We hypothesized that predation reduces population size
Data from: Spatial and spatiotemporal variation in metapopulation structure affects population dynamics in a passively dispersing arthropod

- 摘要：
- t (i) spatial variation in habitat availability decreases variance in metapopulation size and decreases density-dependent dispersal at the metapopulation level, while (ii
