      abstract     = {Litter decomposition plays a critical role in regulating
                      biogeochemical cycles in terrestrial ecosystems and is
                      profoundly impacted by increasing atmospheric nitrogen (N)
                      deposition. Here, a N manipulation experiment was conducted
                      to explore the effects of N additions (0 kg N ha−1 yr−1,
                      20 kg N ha−1 yr−1 and 40 kg N ha−1 yr−1) on decay
                      rates and nutrients release of two contrasting species, the
                      evergreen and nutrient-poor Michelia wilsonii and the
                      deciduous and nutrient-rich Camptotheca acuminata, using a
                      litterbag approach at the western edge of the Sichuan Basin
                      of China. The decay rate and the mineralization of N and
                      phosphorus (P) was faster in nutrient-rich C. acuminata
                      litter than in nutrient-poor M. wilsonii litter, regardless
                      of N regimes. N additions tended to decrease the decay
                      constant (k value) in M. wilsonii litter, but had no effect
                      on C. acuminata litter. N additions had no significant
                      effects on carbon (C) release of both litter types. N
                      additions showed negative effects on N and P release of M.
                      wilsonii litter, particularly in the late decomposition
                      stage. Moreover, for C. acuminata litter, N additions did
                      not affect N release, but retarded P release in the late
                      stage. N additions did not affect the C:N ratio in both
                      litter types. However, N additions—especially high-N
                      addition treatments—tended to reduce C:P and N:P ratios in
                      both species. The effect of N addition on N and P remaining
                      was stronger in M. wilsonii litter than in C. acuminata
                      litter. The results of this study indicate that N additions
                      retarded the nutrients release of two foliar litters. Thus,
                      rising N deposition might favor the retention of N and P via
                      litter decomposition in this specific area experiencing
                      significant N deposition.},
