The Role of Plants in the Effects of Global Change on Nutrient Availability and Stoichiometry in the Plant-Soil System  

The impact on nitrogen ([N][1]) and phosphorus ([P][2]) cycles of human activity is a growing concern and has several causes and consequences ([MacDonald et al., 2011][3]; [Penuelas et al., 2012][4]; [Sardans et al., 2012b][5]). Carbon ([C][6]) inputs by human CO2 emissions and [N][1] inputs from
