摘要: The diversity of vascular plants is very unevenly distributed across the globe. five centres that reach species richness more than 5,000 spp./10,000 km 2 (Costa Rica-Choco, Atlantic Brazil, Tropical Eastern Andes, Northern Borneo, New Guinea) cover only 0.2 % terrestrial surface. On other hand approximately 18,500 spp. are endemic to these which represent 6.2 all plant species. A world map presented based on an extensively expanded data base (more 3,300 figures for different regions world) and a refined methodology. Most global located in mountainous within humid tropics, where suitable climatic conditions high levels geodiversity, i.e., abiotic conditions, coincide. complete review most prominent climatic, geologic, floristic features 20 phytodiversity with 3,000 / 10,000 presented.
