Nature 451:712-5. 2008..A second experiment showed that a decade after cessation of nitrogen addition, relative plant species number, although not species abundances, had recovered, demonstrating that some effects of nitrogen addition are reversible...
- Environmental and plant community determinants of species loss following nitrogen enrichmentChris M Clark
Department of Ecology, Evolution and Behavior, University of Minnesota, St Paul, MN 55108, USA
Ecol Lett 10:596-607. 2007..Our results indicate sensitivity to N addition is co-determined by environmental conditions and production responsiveness, which overwhelm the effects of initial community structure and composition...
