The evolution and expression of dispersal-related traits are intertwined with those of other life-history functions and are manifested within various physiological constraints. Such a relationship is predicted between inbreeding levels and dispersability, which may be anatomically and ontogenetically linked so that the selection pressures on one may affect the other. While both the effect of inbreeding on reproductive success and on dispersal strategies received much attention, only a few studies considered both simultaneously. Furthermore, such studies often rely on two dichotomic representations of breeding and dispersal: using selfing versus outcrossing as a representation of breeding level, and dispersal ratio as the sole representation of dispersal strategy.

花粉来源对异果一年生小pi的种子性状和分散性的影响

与散布有关的性状的进化和表达与其他生活史功能相互交织，并在各种生理学约束下表现出来。可以预测近交水平和分散性之间的这种关系，这在解剖学上和个体发育上可能是联系在一起的，因此一个人的选择压力可能会影响另一个人。近交对生殖成功和传播策略的影响都引起了广泛关注，但只有少数研究同时考虑了两者。此外，此类研究通常依赖于繁殖和传播的两个二分法表示：使用自交与异源杂交作为繁殖水平的代表，而传播比作为传播策略的唯一代表。
