  1. Consistent individual tendencies in behaviour, or behavioural types, are likely to impact the dynamics and outcomes of animal‐mediated seed dispersal. We review the extant literature on this issue and outline a conceptual overview to guide this emerging field. We provide an overview of possible ways in which behavioural types can affect animal‐mediated seed dispersal. We summarize theoretical mechanisms linking behavioural types with seed dispersal outcomes and review how behavioural types might affect each stage of seed dispersal, beginning with fruit encounter and harvest, and ending with events that take place after seed deposition.
  2. Since behavioural types involve correlations among different behaviours (i.e. behavioural syndromes), they can generate unexpected associations between different decisions that are involved in seed dispersal, with conflicting (or reinforcing) effects on different stages of seed dispersal. Thus, we draw particular attention to trade‐offs faced by seeds dispersed by individuals with different behavioural tendencies. We also note that since seed dispersal is a multiplicative process with different stages, disperser behavioural types that provide moderately efficient dispersal at each stage will be better for plants than behavioural types that are very efficient at some steps, but inefficient on others. Finally, we provide testable predictions on the links between behavioural types and characteristics of seed dispersal, including, for example, influences on the probability of seed harvest, dispersal distance, deposition sites and condition of dispersed seeds.
  3. We argue that investigating the links between behavioural types and animal‐mediated seed dispersal will provide a better mechanistic understanding of seed dispersal and plant regeneration.

动物性格与种子传播:概念回顾

  1. 个体行为或行为类型的一致性趋势可能会影响动物介导的种子传播的动力和结果。我们回顾了有关此问题的现有文献,并概述了概念概述以指导这一新兴领域。我们概述了行为类型可能影响动物介导的种子传播的可能方式。我们总结了将行为类型与种子传播结果联系起来的理论机制,并回顾了行为类型如何影响种子传播的每个阶段,从果实的接触和收获开始,到种子沉积后发生的事件结束。
  2. 由于行为类型涉及不同行为(即行为综合症)之间的相关性,因此它们可以在涉及种子散布的不同决策之间产生意外的关联,从而对种子散布的不同阶段产生冲突(或增强)的影响。因此,我们特别注意那些行为行为不同的人散布的种子所面临的取舍。我们还注意到,由于种子散播是一个具有不同阶段的乘法过程,因此,在每个阶段提供适度有效散播的分散器行为类型,对于植物而言,比在某些步骤中非常有效但在其他步骤中效率不高的行为类型更好。最后,我们对行为类型与种子传播特征之间的联系提供了可检验的预测,例如,
  3. 我们认为,调查行为类型与动物介导的种子传播之间的联系将提供对种子传播和植物再生的更好的机械理解。
