Ungulate stimulation of nitrogen cycling and retention in Yellowstone Park grasslands

  title={Ungulate stimulation of nitrogen cycling and retention in Yellowstone Park grasslands},
  author={Douglas A. Frank and Peter M. Groffman and R. D. Evans and Benjamin F. Tracy},
We studied how ungulates and a large variation in site conditions influenced grassland nitrogen (N) dynamics in Yellowstone National Park. In contrast to most grassland N studies that have examined one or two soil N processes, we investigated four rates, net N mineralization, nitrification, denitrification, and inorganic N leaching, at seven paired sites inside and outside long-term (33+ year) exclosures. Our focus was how N fluxes were related to one another among highly variable grasslands… CONTINUE READING
