In response to increasing carbon dioxide levels, most general circulation
models (GCMs) predict increasing temperatures and decreasing precipitation
for the central hardwood region of the United States. Plants in
this region will need to adapt to these changes as well as to other
stress agents if they are to germinate, grow, and reproduce. For
the last five years, our research program under the global change
initiative has been designed to increase our understanding of the
physiological and genetic mechanisms used by plants to respond and
adapt to multiple stresses in forest ecosystems. To achieve this
objective, we have conducted a series of field, greenhouse, and
laboratory studies aimed at understanding how plants respond to
allelochemicals, drought, and competition.
