Ph.D. SDSU/U.C. Davis in Ecology 1996
B.Sc. University of Edinburgh (honours) 1985
After tutelage under Paul Jarvis and John Grace at the University of
Edinburgh, and an Honours project looking at the influence of needle length
and angle on apical bud temperatures of 4 conifer species, Derek came to
SDSU to work with Walter Oechel on ecophysiology in chaparral shrubs.
His research focused on seasonal patterns and variation within and
between Ceanothus shrubs in water potential, photosynthesis, nutrients,
carbon storage and translocation, and seed weight. This work formed
Derek's doctoral dissertation which he completed at the end of 1996.
Derek has worked on several other chaparral projects under SDSU's Systems
Ecology Research Group working on chaparral regeneration after fire in
response to fuel load and water potential tolerances of chaparral seedlings.
In addition, Derek has performed research for CALTRANS on riparian
mitigation monitoring and worked for the City of San Diego, Environmental
Services Department on vernal pool protection, municipal waste stream and
planning issues.
In January 1997 he started work for the County of San Diego, Department of
Planning and Land Use as an Environmental Management Specialist. He is
working on regional conservation plans including the the county segment of
the Multiple Species Conservation Plan (MSCP), the MSCP North County
subarea, and the east county Multiple Habitat Conservation and Open Space
Plan (MHCOSP). Together these plans and preserves should conserve the many
rare, threatened and endangered species that are present in San Diego
County, many of which are endemic to the county which was recognized in an
article in the January 24 1997 issue of Science as a national endangered
species hot spot.
