How Nitrogen Deposition Affects Tropical Forest Plant Diversity

Jan 17, 2011

In 2010, Dr. LU Xiankai, Prof. MO Jiangming and his colleagues from South China Botanical Garden, Chinese Academy of Sciences (SCBG) found that elevated N deposition may decrease plant diversity of “N-rich” forests (see Lu et al., Global Change Biology, 2010, 16: 2688–2700). On the base of this finding, their further study in Dinghushan Biosphere Reserve for six years showed that responses of plant diversity in reforested forests varied with different land-use history. This is the first report on the interactive effects between N deposition and land-use practice on plant diversity in tropical areas.

These results suggest that land-use history plays an important role on determining the response of forest plant diversity to N deposition. It also has great significance for valuing changes of forest biodiversity under the background of intensive human activity and elevated atmospheric N deposition in the future.
