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

摘要:
Allee effects are thought to mediate the dynamics of population colonization, particularly for invasive species. However, Allee effects act
Data from: Evidence of a component Allee effect driven by predispersal seed predation in a plant (Pedicularis rex, Orobanchaceae)

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

摘要:
. 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
