谱系多样性(Phylogenetic diversity,PD)定义为在系统发育树上跨越给定的一组分类群所经过的所有系统发育分支的最小总长度(Faith,1992)。 Phylogenetic diversity (PD) index proposed by Faith (1992). Faith’s PD is defined as the total branch length spanned by the tree including all species in a local ...

Stacked Faith's phylogenetic diversity (SFPhD) enables calculation of this widely adopted diversity metric at a much larger scale by implementing a computationally efficient algorithm. The algorithm reduces the amount of computational resources required, resulting in more accessible software with a reduced...
