Traditional attempts to delineate floristic regions typically focus on species distributions, often ignoring the rich context that phylogenetic relationships can provide. In this study, we explore how phylogenetic relatedness, taxonomic composition, and regional phylogenetic structure change across a global biodiversity hotspot region, Yunnan, located in southwestern China. We propose a system ...

The development of standardised vocabularies within nursing has been an important research activity for a number of years. Current representations generally take the form of taxonomic vocabularies. These are seen as important as they provide a structure for retrieving and analysing data from automated systems. However, there is increasing evidence to show that traditional taxonomic vocabularies...

Statistical properties of the taxonomic classification of human languages are studied. It is shown that, at the highest levels of the taxonomic hierarchy, the frequency of taxon members as a function of the number of languages belonging to each member decays as a power law. This feature reveals that a self-similar structure underlies the taxonomy of languages, exactly as observed in the taxonom...
