cluding forests, have shown short-term losses of soil carbon as
CO 2 and acceleration of nitrogen cycling rates, leading to an in-
crease in the availability of nitrogen to the vegetation (15–20). The
principles of ecosystem stoichiometry (21–23) suggest that, in
forest ecosystems, the redistribution of a relatively small amount
of this newly available nitrogen from the soil to the trees could
result in a substantial increase in carbon storage in woody tissues
