Abstract:

The application of phylogenetic relationships helps us to understand species composition and species distribution patterns, which provide a scientific basis for the effective protection and sustainable use of biological diversity. Phylogenetic diversity (PDfaith), based on branch lengths of the phylogenetic tree, is the most basic measurement index. Many indices are derived from PDfaith, which makes difficult to choose the most appropriate parameters. The most effective and feasible way is to select suitable indices based on specific research questions, and some examples have been presented in plant phylofloristics and biodiversity conservation. DNA sequences have rapidly accumulated particularly through the global DNA barcoding project, which provides a standardized mass data, and can be used to reconstruct mega-phylogeny. But studies conducted around the phylogenetic diversity require more information, specifically data on species distribution, environmental factors, and climatic data. In addition, some fundamental questions need to be verified, such as the relationship between phylogenetic diversity and ecosystem functions.

Key words: evolutional history, DNA barcoding, megaphylogeny, biodiversity, flora, conservation
