由于扩散对局部适应、种群功能或分布范围变化具有影响，它被视为种群持续存在和物种进化的核心过程。然而，测量扩散是复杂的，这使得使用扩散替代指标具有合理性。尽管体型作为一种扩散替代指标具有吸引力，且与扩散存在普遍联系，但事实证明它并不令人满意。我们在此提出的假设是，鉴于扩散综合征的存在，一系列生活史特征可能是替代的、更合适的扩散替代指标。我们以蝴蝶作为模式系统对这一想法进行了检验。我们证明了扩散过程的不同要素（即个体移动速率、距离和基因流）与不同系列的生活史特征相关：扩散的这些不同要素形成了不同的综合征，并且必须被视为一个物种生态位的实际维度。然后我们表明这些综合征能够对扩散进行准确预测。使用生活史特征将仅基于翅大小所做推断的精度提高了多达五倍。因此，这种基于特征的预测提供了可靠的扩散推断，能够为旨在研究蝴蝶种群以及可能其他生物在环境变化下的动态和进化的模拟模型提供数据，以帮助对它们进行保护。
Due to its impact on local adaptation, population functioning or range shifts, dispersal is considered a central process for population persistence and species evolution. However, measuring dispersal is complicated, which justifies the use of dispersal proxies. Although appealing, and despite its general relationship with dispersal, body size has however proven unsatisfactory as a dispersal proxy. Our hypothesis here is that, given the existence of dispersal syndromes, suites of life-history traits may be alternative, more appropriate proxies for dispersal. We tested this idea by using butterflies as a model system. We demonstrate that different elements of the dispersal process (i.e., individual movement rates, distances, and gene flow) are correlated with different suites of life-history traits: these various elements of dispersal form separate syndromes and must be considered real axes of a species' niche. We then showed that these syndromes allowed accurate predictions of dispersal. The use of life-history traits improved the precision of the inferences made from wing size alone by up to five times. Such trait-based predictions thus provided reliable dispersal inferences that can feed simulation models aiming at investigating the dynamics and evolution of butterfly populations, and possibly of other organisms, under environmental changes, to help their conservation.
