Warming-induced decline in ecosystem services is mitigated by plant traits on the Tibetan Plateau

摘要：

Introduction Experimental studies of how global changes and human activities affect plant diversity often focus on broad measures of diversity and discuss the implications of these changes for ecosystem function.We examined how experimental warming and grazing affected species within plant groups of direct importance to Tibetan pastoralists : medicinal plants used by humans and palatable plants consumed by domestic livestock.We posed the following questions : How do experimental warming and grazing affect the number of medicinal and palatable plant species ?Is one plant group relatively more vulnerable to species losses than the other ?Are plant traits associated with particular plant use groups ?If so,do the plant traits mediate the medicinal and palatable plant group responses ?
