Research
Program Summary
Understanding
the paleobiology and paleoecology of ancient conifers and their environmental
stresses throughout geologic time, requires integrated geological and
botanical investigations, emphasizing plant anatomy, morphology, and
systematics, combined with analyses of depositional environments, geochemistry,
taxonomy, and plant/animal associations, in several different terrestrial
and marine ecosystems. This primary research base has expanded in recent
years to include neoenvironmental studies in both physical and life
sciences, as well as environmental monitoring and environmental policy
decisions.
