Patterns of vascular plant diversity at continental to global scales.

摘要: MUTKE, J. & BARTHLOTT, W. 2005. Patterns of vascular plant diversity at continental to global scales. Biol. Skr. 55: 521-531. ISSN 0366-3612. ISBN 87-7304-304-4. The studies presented in this paper analyse patterns land plants (mosses, ferns, gymnosperms, and angiosperms) A revised version our earlier world map species richness the first maps mosses gymnosperms on a scale are presented. Diversity correlated with different measures geodiversity (the abiotic environment). Global centres coincide highly structured, geodiverse areas tropics subtropics. These Choco-Costa Rica region, tropical eastern Andes north western Amazonia, Brazil, northern Borneo, New Guinea, as well South African Cape southern Mexico, East Himalaya, Sumatra, Malaysia, Madagascar. Constraints imposed by physical environment, such length thermal vegetation period or water availability, shape large trends biodiversity. However, important endemism can only be explained when taking into account history floras. main SE Asia same for all other plants, but parts subtropics there is low gymnosperm diversity. exceptions pattern Mexico California, which have almost many Asia. increase number genera published during last 250 years documented, based data from Index Kewensis. Cactaceae genus level used show how choice taxonomic affects analysis its implications priority setting biodiversity conservation. In context, hotspots discussed an alternative proposed.
