基于线粒体DNA （mtDNA）数据，许多跨越多个生物地理区域的生物表现出跨越这些区域之间过渡区的遗传结构，而其他生物则表现出遗传同质性。在这种空间遗传不连续性的存在与否与物种的扩散潜力之间没有发现明确的联系，这混淆了有关遗传结构的一般预测的表述。mtDNA和核标记之间的差异在半透性屏障中很常见，这表明结构的缺乏可能归因于mtDNA特异性的遗传特性。通过比较mtDNA数据和核DNA数据，我们重新研究了大西洋/印度洋生物地理过渡带中以单一mtDNA谱系为代表的沿海蟹圆形膜虫的遗传结构。
Based on mitochondrial DNA (mtDNA) data, many organisms with ranges spanning multiple biogeographical regions exhibit genetic structure across the transition zones between these regions, while others appear to be genetically homogenous. No clear link has been found between the presence or absence of such spatial genetic discontinuities and species' dispersal potential, confounding the formulation of general predictions concerning genetic structure. The fact that discrepancies between mtDNA and nuclear markers are common across semi‐permeable barriers suggests that a lack of structure could be attributable to mtDNA‐specific properties of inheritance. We re‐examined genetic structure in the coastal crab Hymenosoma orbiculare, a species that is represented by a single mtDNA lineage across the Atlantic/Indian Ocean biogeographical transition zone, by comparing mtDNA data with nuclear DNA data.
