本文探讨了在何种程度上有层次信息的区域关系中包含的澳大利亚脊椎动物的分布。分布的属，其所包括的物种，其所包括的亚种（适当时）编码存在/不存在的14个地区的特有现象。然后分析数据的分支和最简约的区域构建分支图，自助一致的树被用来评估分支信号的强度。 鸟类和哺乳动物的分布被发现在它们的等级模式上几乎是相同的，蛇也有着相同的区域关系的一般模式。青蛙和蜥蜴表现出更大的差异，但在某些方面仍然一致。这种一致性需要一个一般性的解释。有人提出，无论是模式可以解释（1）真正的区域关系（vicariance），在这种情况下，地理噪音，包括冗余的分布和广泛的类群不干扰历史信号;（2）过程或事件的限制，导致一致的世界主义的历史;或（3）两者的组合。
This paper investigates the extent to which there is hierarchical information about area-relationships contained in the distributions of Australian vertebrates. Distributions of genera, their included species, and their included subspecies (when appropriate) were coded present/absent for 14 areas of endemism. The data were then analysed cladistically and most parsimonious area-cladograms constructed; bootstrap consensus trees were used to assess the strength of the cladistic signal. Distributions of birds and mammals were found to be nearly identical in their hierarchical pattern, and snakes shared the same general pattern of area-relationships. Frogs and lizards exhibited greater differences but were still congruent in some respects. This congruence calls for a general explanation. It is proposed that either the pattern can be explained in terms of (1) true area-relationships (vicariance), in which case biogeographic noise, including redundant distributions and widespread taxa do not disturb historical signal; (2) constraints on processes or events that lead to congruent histories of cosmopolitanism; or (3) a combination of both.
