    Description

    Stable isotopes of nitrogen (N) in plants are increasingly used to evaluate ecosystem N cycling patterns. A basic assumption in this research is that plant δ15N reflects the δ15N of the N source. Recent evidence suggests that plants may fractionate on uptake, transport, or transformation of N. If the dominant source of plant N is via roots, a difference in δ15N by tissue type would suggest fractionation on transport and assimilation of N. In order to evaluate differences between species and plant parts, we measured δ15N in root, stem, and leaf tissues of individual sugar maple (Acer saccharum; SM) and American beech (Fagus grandifolia; BE) plants ranging in age from germinants to mature trees at the Hubbard Brook Experimental Forest, New Hampshire (USA).
