I’m a plant physiological ecologist with research interests in
restoration ecology, ecosystem ecology, and biogeochemistry. I’m
particularly interested in how plant traits can alter ecosystem
functioning through their effects on soils and nutrient cycling.
Some invasive species have the capacity to affect biogeochemical
cycling, and in many cases soil disturbance, or alterations to
soil nutrient regimes, feed back to encourage invasion by
exotics. Restoration ecology must therefore take into account
not only the presence of invasive species, but the interactions
between plants and soils, in order to suggest effective
management tactics. I also maintain research interests in unique
soil-plant interactions, such as the pygmy forest community
along the Mendocino coast, and on tropical soils and nutrient
cycles.
Currently, I have two ongoing restoration experiments—a star
thistle eradication and monitoring experiment in Mendocino
County, and a perennial grass restoration experiment at Ulistac
Natural Area, just a few miles from the SCU campus. The latter
project is testing whether mitigating the probable nitrogen
saturation of the disturbed Ulistac soils can help favor native
species over exotic thistles and annual grasses. In winter 2007,
I will be recruiting biology or environmental science students
to get research units—and potentially a publication—for work on
this experiment. For more information on doing restoration
ecology research, please contact me |
