系统发育多样性(PD)是一种生物多样性的衡量标准，它考虑了不同类群之间的系统发育关系(即进化历史)。因此，与分类学上的丰富度相比，它可能为保护评估提供更好的货币。在这里，我们证明，与最近的断言相反，在互补保护区选择的背景下，优化工具可以用于最大化PD，并且最大化属多样性和PD的地点集合之间的空间重叠不能用作第一个衡量标准是第二个衡量标准的良好替代的证据。然而，在我们自己使用南非西北部鸟类属的数据进行的分析中，我们发现，当最大化这两种生物多样性衡量标准中的每一种时，在选择互补的地点集方面取得了几乎同样有效的结果。(C)2002爱思唯尔科学有限公司。保留所有权利。
Phylogenetic diversity (PD) is a biodiversity measure that takes account of phylogenetic relationships (hence evolutionary history) between taxa. It may therefore provide a better currency for conservation evaluation than taxonomic richness. Here, we demonstrate that, contrary to recent assertions, optimisation tools can be used to maximise PD in the context of complementary reserve selection, and that the spatial overlap between sets of sites maximising genus diversity and PD cannot be used as evidence that the first measure is a good surrogate for the second. Nevertheless, in our own analyses using data on bird genera in northwest South Africa we found that near equally effective results are obtained in the selection of complementary sets of sites when maximising for each of these two measures of biodiversity.
