Data from: Information-mediated Allee effects in breeding habitat selection

- 摘要：
- ‘information providers’ as cues for high-quality habitat. This constitutes what we term an ‘information-mediated Allee effect’. We present the fir

- 摘要：
- e is a sharp transition around a specific threshold population size. In the ecological literature, such threshold phenomena are called “strong Allee effect

- A small or sparse population may suffer a reduction in fitness due to Allee effects. Here we explored effects of plant density on pollination

- . While the Allee effect (where individuals in low-density populations suffer lowered fitness) is known to influence both the ecological and evolutionary dynamics
Data from: Dispersal evolution in the presence of Allee effects can speed up or slow down invasions
