人们传统上认为生物多样性集中在热带地区。然而，南美洲南部、南非、新喀里多尼亚、澳大利亚和泛北极受威胁的温带地区拥有大量独特的分类群。分支图中编码的系统发育信息可用于制定衡量生物多样性的指数。应用这些指数的菊科（被子植物）和Asterlionoidea（鞘翅目）表明温带地区的生物多样性保护的相关性：他们是丰富的生物遗传学上有价值的物种和环境受到威胁。
It has been accepted traditionally that biodiversity is concentrated in the tropics. However, threatened temperate areas in southern South America, South Africa, New Caledonia, Australia and the Holarctic possess a significant number of unique taxa. Phylogenetic information encoded in cladograms can be used to develop indices for measuring biodiversity. Application of these indices to Asteraceae (Angiosperms) and Curculionoidea (Coleoptera) indicates the relevance of the temperate areas to biodiversity conservation: they are rich in phylogenetically valuable species and are environmentally threatened.
