  1. This study investigated N capture by Plantago lanceolata L. and Brassica napus L. from complex organic material (dual-labelled with 15N/13C) added either as a thin concentrated layer (discrete patch treatment) or dispersed uniformly with the…
  2. This paper combines the world's protected areas (PAs) under the Convention on Biological Diversity (CBD), common classification systems of ecosystem conservation status, and current knowledge on ecosystem responses to nitrogen (N) deposition to…
  3. We investigated N cycling and denitrification rates following five years of N and dolomite amendments to whole-tree harvested forest plots at the long-term soil productivity experiment in the Fernow Experimental Forest in West Virginia, USA. We…
  4. To better constrain the dynamics of the dissolved organic nitrogen (DON) pool and the role of N2 fixation in the nitrogen cycle at the Bermuda Atlantic Time-series Study (BATS) site, we measured the 15N/14N ratio of total nongaseous nitrogen (TN) in…
  5. Net N mineralization, nitrification, and N uptake were monitored in the A (0-8 cm) and B (8-30 cm) soil horizons from 1997 to 1999 across a chronosequence of upland hardwood forest stands in southern Indiana, USA. Stand ages were 1, 6, 12, 31, and…
  6. We measured the 15N natural abundance values of 320 individuals belonging to 45 different plant species of the Brazilian cerrado. We also determined delta15N of soil nitrogen as a function of soil depth. Our purpose was to test the hypothesis that…
  7. Precision of estimation of the proportion of legume N derived from N2 fixation (%Ndfa) was assessed in relation to subterranean clover (Trifolium subterraneum L.) pastures and crops of pea (Pisum sativum L.) and lupin (Lupinus angustifolius L.)…
  8. Urbanization can potentially alter watershed nitrogen (N) retention via combined changes in N loading, water runoff, and N processing potential. We examined N export and retention for two headwater catchments ($4km2) of contrasting land use (16% vs.…
  9. We examined the hypothesis that nutrients from land sources are enhancing the food supply for fish in coastal reefs of northwestern Cuba. Spatial variation in stable isotope ratios (13 C and 15 impacted by mixed pollution sources in Havana City,…
