Long-term changes in composition, diversity and distribution patterns in four herbaceous plant communities along an elevational gradient

摘要

QuestionsHave species expanded their ranges upward in elevation? Have - and -diversity changed over time? Have species richness changes along the gradient shown distributional patterns? Have community compositions changed over time, and if so, which plant families are responsible for variation? Do herbaceous changes correspond to increased warming, overstorey shifts and disturbance events at each site?
