Physiological mechanisms influencing plant nitrogen isotope compositionR D Evans
University of Arkansas Stable Isotope Laboratory, Biological Sciences, University of Arkansas, Fayetteville, AR 72701, USA
Trends Plant Sci 6:121-6. 2001..Future work must address acquisition of organic nitrogen from the soil solution, the role of mycorrhizae, and internal transformations within the plant...
Bromus tectorum invasion alters nitrogen dynamics in an undisturbed arid grassland ecosystemL J Sperry
Department of Biology, University of Arkansas, Fayetteville, Arkansas 72701, USA
Ecology 87:603-15. 2006..Lack of new inputs combined with continued loss will result in lower total soil N, evidenced by the lower total soil N in the invaded/disturbed communities...
