Effect of grazing on the plant functional group diversity and community biomass and their relationship along a precipitation gradient in Inner Mongolia Steppe
Abstract:There has been a rapidly increasing interest in the effect of species diversity or functional group diversity on ecosystem productivity. In order to search a general diversity-productivity pattern and find the mechanisms underlying the pattern, ecologists have undertaken many empirical studies. But the diversity-productivity connection still remains unclear. The main purpose of this study was to examine the effect of plant species diversity and functional group diversity on productivity of different communi...
