- 摘要：
- 1. Allee effects occur when the aggregation of individuals result in mutually beneficial intraspecific interactions whereby individual fitness, or pe
Data from: Spatial variation in Allee effects influences patterns of range expansion

- 摘要：
- Allee effects are thought to slow range expansion and contribute to stable range boundaries. Recent studies have shown Allee effects to vary

- 摘要：
- Allee effects are thought to mediate the dynamics of population colonization, particularly for invasive species. However, Allee effects act
