Colonization of new areas may entail shifts in diversification rates linked to biogeographical movement (dispersification), which may involve niche evolution if species were not exapted to new environments. Scleria (Cyperaceae) includes c. 250 species and has a pantropical distribution suggesting an extraordinary capacity for long‐distance dispersal and colonization. We investigate patterns of diversification in Scleria, and whether they are coupled with colonization events, climate niche shifts or both.

是什么推动了具有超长距离散布和定植能力的泛热带植物谱系中的多样化？

新地区的殖民化可能导致与生物地理运动（分散化）有关的多样化率发生变化，如果物种不适合新环境，则可能涉及生态位的演变。菌核（莎草科）包括c。有250种，并且具有泛热带分布，这表明其具有长距离分散和定居的超强能力。我们调查了Scleria的多样化模式，以及它们是否与定殖事件，气候利基变化或两者同时发生。
