两性二态性与物种多样性之间存在着从正相关到负相关甚至不显著的关系。尽管已经提出了许多假设来解释这些关系，但事实证明很难理解为什么模式如此多变。关于这一主题的大多数研究都使用枝作为系统发育独立的复制来进行模式分析，但最近的一些研究采用了另一种方法，使用位点作为空间独立的复制。我们讨论了新的、基于地点的研究如何补充传统的、基于进化枝的研究，并认为这两种方法的结合使用将比单独使用更有效地理解产生两性二态-物种多样性关系变化的环境因素。
A variety of relationships have been observed between sexual dimorphism and species diversity, from positive to negative and nonsignificant. Although many hypotheses have been proposed to explain these relationships, it has proven difficult to understand why patterns are so variable. Most studies on this topic have used clades as phylogenetically independent replicates for pattern analysis, but a few recent studies took an alternative approach, using sites as spatially independent replicates. We discuss how the new, site-based studies complement the traditional, clade-based studies and argue that the combined use of the two approaches will be more powerful than either alone in understanding environmental factors that produce variation in sexual dimorphism–species diversity relationships.
