Allee效应描述了一种情况，即低数量的种群受到种群增长率和密度之间的正相关关系的影响，这增加了它们灭绝的可能性。这一动态过程在生态学中的重要性一直被低估，最近的证据表明，它可能对许多植物和动物物种的种群动态产生影响。研究小种群中产生Allee效应的因果机制可以为理解其动态提供关键的信息。
The Allee effect describes a scenario in which populations at low numbers are affected by a positive relationship between population growth rate and density, which increases their likelihood of extinction. The importance of this dynamic process in ecology has been under-appreciated and recent evidence now suggests that it might have an impact on the population dynamics of many plant and animal species. Studies of the causal mechanisms generating Allee effects in small populations could provide a key Ito understanding their dynamics.
