- Net primary productivity and rain-use efficiency as affected by warming, altered precipitation, and clipping in a mixed-grass prairieXia Xu
Department of Microbiology and Plant Biology, University of Oklahoma, Norman, OK 73019, USA
Glob Chang Biol 19:2753-64. 2013..Additionally, results from single-factor manipulative experiments should be treated with caution due to the non-additive interactive effects of warming with altered precipitation and land use (clipping). ..
- Nitrogen regulation of the climate-carbon feedback: evidence from a long-term global change experimentShuli Niu
Department of Botany and Microbiology, University of Oklahoma, Norman, Oklahoma 73019, USA
Ecology 91:3261-73. 2010..Our results suggest that increased ecosystem nitrogen use efficiency via a shift in species composition toward C4 dominance rather than plant N uptake is a key mechanism underlying warming stimulation of plant biomass growth...
- Prolonged suppression of ecosystem carbon dioxide uptake after an anomalously warm yearJohn A Arnone
Desert Research Institute, Reno, Nevada 89512, USA
Nature 455:383-6. 2008..Our findings suggest that more frequent anomalously warm years, a possible consequence of increasing anthropogenic carbon dioxide levels, may lead to a sustained decrease in carbon dioxide uptake by terrestrial ecosystems...
