Trends of the Herbs Ecological Evolution

2012
The results of analytic research show that the evolution of leaf structure and water balance are completely coincident to global changes of planet climate and hydrology. Taxonomical diversity of herbs and herbaceous biomes is the function of paleoclimate variability and plant adaptogenesis to it.
