Ecological or geological phenomena can impose limits on geographic diversification that cause biogeographical patterns of distantly related but sympatrically occurring taxa to be similar. Concordant patterns of diversity facilitate conservation management because strategic designation of protected areas can capture complementary rather than redundant components of variation. Here we demonstrate that on the biodiverse Indonesian island of Sulawesi, seemingly idiosyncratic distributions of diversity in endemic monkeys (Macaca species) and toads (Bufo celebensis) are actually virtually identical on a fine geographic scale. It appears that range fragmentation has generated seven multi-taxon areas of genetic endemism, each of which should be targeted for conservation. Joint consideration of molecular phylogeography, morphology, and demography helps resolve apparent contradictions in paraphyletic macaque mitochondrial DNA and in undifferentiated toad morphology, and facilitates an understanding of biogeography and conservation genetics of Sulawesi fauna.
生态或地质现象会对地理多样化施加限制，从而导致远缘但同域分布的分类群呈现出相似的生物地理格局。一致的多样性格局有助于保护管理，因为保护区的战略指定能够涵盖变异的互补而非冗余部分。在此，我们证明，在生物多样性丰富的印度尼西亚苏拉威西岛上，特有猕猴（猕猴属物种）和蟾蜍（西里伯斯蟾蜍）看似独特的多样性分布，在精细的地理尺度上实际上几乎是相同的。似乎是分布片段化产生了七个多分类群的遗传特有区域，每个区域都应作为保护目标。综合考虑分子系统地理学、形态学和种群统计学，有助于解决猕猴线粒体DNA的并系现象以及蟾蜍形态未分化中明显的矛盾，并促进对苏拉威西岛动物群生物地理学和保护遗传学的理解。
