Communities arising through adaptive radiation are generally regarded as unique, with speciation and adaptation being quite different from immigration and ecological assortment. Here, I use the chronological arrangement of the Hawaiian Islands to visualize snapshots of evolutionary history and stages of community assembly. Analysis of an adaptive radiation of habitat-associated, polychromatic spiders shows that (i) species assembly is not random; (ii) within any community, similar sets of ecomorphs arise through both dispersal and evolution; and (iii) species assembly is dynamic with maximum species numbers in communities of intermediate age. The similar patterns of species accumulation through evolutionary and ecological processes suggest universal principles underlie community assembly.
通过适应性辐射产生的群落通常被视为独特的，其物种形成和适应与迁入和生态分类截然不同。在这里，我利用夏威夷群岛的时间顺序排列来直观呈现进化历史的快照以及群落组装的阶段。对与栖息地相关的多色蜘蛛的适应性辐射分析表明：（i）物种组装并非随机；（ii）在任何群落中，相似的生态形态组通过扩散和进化都会出现；（iii）物种组装是动态的，中等年龄群落中的物种数量最多。通过进化和生态过程的相似物种积累模式表明，群落组装存在普遍原则。
