Summary Among flowering plants, self‐compatibility, longer lifespan, and generalized pollination syndrome are each thought to increase the lifetime odds of finding a mate, particularly in isolated locales. An accumulated body of evidence supports the role of breeding system in island colonization, but less is known about the impact of other traits and their interactions during establishment. We employ a global dataset of 3222 flowering plant species from 169 families to estimate the effects of traits on the probability of island occurrence. Our analyses additionally account for taxonomic group membership and assess the role of island arrival opportunity. Self‐compatibility is strongly associated with island colonization. A longer lifespan and generalized pollination syndrome are also associated with increased island colonization, although this is influenced by their interaction with breeding system. The probability of island colonization is highly dependent on taxonomically conserved unmeasured traits and arrival opportunity. As expected, mate limitation appears to increase with dispersal distance, although many other factors are at play. We find that arrival opportunity and breeding system are the primary drivers of island colonization relative to other life‐history traits we account for here, lending additional support for the positive role of uniparental reproduction in establishment following long‐distance dispersal.

开花植物的岛屿定植是由繁殖系统、寿命、花对称性和到达机会的相互作用决定的


摘要 在开花植物中，自交性、更长的寿命和广义授粉综合症都被认为会增加一生找到配偶的几率，尤其是在偏远地区。积累的大量证据支持繁殖系统在岛屿殖民中的作用，但对其他性状的影响及其在建立过程中的相互作用知之甚少。我们采用来自 169 个科的 3222 种开花植物物种的全球数据集来估计性状对岛屿出现概率的影响。我们的分析还考虑了分类群成员资格，并评估了岛屿到达机会的作用。自交性与岛屿定植密切相关。更长的寿命和普遍授粉综合征也与岛屿定植的增加有关，尽管这受到它们与繁殖系统相互作用的影响。岛屿定殖的可能性在很大程度上取决于分类学上保守的未测量特征和到达机会。正如预期的那样，配合限制似乎随着分散距离的增加而增加，尽管还有许多其他因素在起作用。我们发现，相对于我们在这里解释的其他生活史特征，到达机会和繁殖系统是岛屿殖民的主要驱动因素，为单亲繁殖在长距离传播后建立中的积极作用提供了额外的支持。
