| Outreach |
|
Kids Do Ecology- conducted an ecology experiment with 5th
graders at Franklin School, Goleta, California. This project was designed
to introduce minorities to the importance of field ecology. |
|
|
Workshops on Population Viability Analysis- every year I teach a 1-day
long workshop to ~30 attendees to teach population modeling techniques to
conservation practitioners. Attendees usually included practitioners from
the National Parks Service, US Fish and Wildlife, the Nature Conservancy,
the Center for Plant Conservation, and botanical gardens from around the
US. |
| Reviewer for Journals/Books |
|
I review approximately 2 papers per month, and have served as a reviewer
at least once for the following journals and book publishers: American
Naturalist, American Midland Naturalist, Annals of Botany, Biological
Conservation, Ecological Applications, Ecology, Ecology Letters,
Evolution, Functional Ecology, International Journal of Plant Sciences,
Journal of Ecology, Journal of the Torrey Botanical Society, Madrono,
Natural Areas Journal, Oecologia, Plant Species Biology, University of
Chicago Press. |
