Continental‐scale spatial phylogenetics of Australian angiosperms provides insights into ecology, evolution and conservation

摘要: Aim Biodiversity studies typically use species, or more recently phylogenetic diversity (PD), as their analysis unit and produce a single map of observed diversity. However, biodiversity is not necessarily an indicator significant therefore should be used alone. By applying small number additional metrics to PD, with associated statistical tests, we can determine whether less the phylogeny occurs in area, branch lengths area are longer shorter, long short-branched endemism than expected under null model. Location Australian continent. Methods We sampling 90% Australia's angiosperm genera, 3.4 million georeferenced plant specimens downloaded from Virtual Herbarium (AVH), calculate relative (RPD) (RPE). Categorical neo- palaeo-endemism (CANAPE) randomization tests were performed significance. Results We identify several combinations PD across continent that seen using patterns Joint interpretation these complements previous interpretations evolutionary history. Of conservation concern, only 42% cells found here overlap existing nature reserves. Main conclusions These spatial methods feasible apply whole flora at continental scale. Observed richness inadequate fully understand biodiversity. The combination applied better explain ecological processes have created them. this paper also priorities any geographical scale taxonomic level.
