Fig. 1From: High nutrient uptake efficiency and high water use efficiency facilitate the spread of Stellera chamaejasme L. in degraded grasslandsStoichiometric characteristics (Mean ± SE) of C, N, P, C/N, C/P and N/P ratios in S. chamaejasme as affected by degradation degree. Values designated by different capital letters were significantly different among the four degraded grasslands levels (P < 0.05). The same applies belowBack to article page
