Ecology & Invertebrate Zoology
James M. Watanabe received his PhD in zoology from UC Berkeley. His
background and research interests lie in the fields of invertebrate
zoology and marine ecology, with particular emphasis on kelp forests
and rocky intertidal communities. Prior to joining the faculty at
Stanford University's Hopkins Marine Station in 1994, he directed the
research program at the
Monterey Bay Aquarium for 10 years.
Watanabe has conducted research on the distribution and abundance of
kelp forest invertebrates, the dynamics of sea urchin-mediated
deforestations, and the physiological ecology of kelp (Macrocystis
pyrifera and Pterygophora californica).
These studies have focused on predator-prey interactions, interspecific
competition, and the effects of disturbance on marine organisms. He is
also interested in the statistical problems of detecting changes in
natural populations through time.
Watanabe's primary responsibility at Hopkins Marine Station is
undergraduate teaching. During winter, spring, and summer quarters he
teaches subjects ranging from introductory biology and invertebrate
zoology to kelp forest ecology, experimental design, and statistics.
His courses attempt to nuture an appreciation for the natural world
through accumulation of detailed knowledge and hands-on experience.
Watanabe has supervised numerous undergraduate research projects and
honors theses, with topics ranging from the effects of spatial scale on
distribution of intertidal invertebrates, diversity of subtidal rock
wall assemblages, and effects of nitrogen limitation on red algal
pigments, to foraging behavior of sea otters, impacts of harbor seal
haul-out behavior on sessile intertidal communities, and intertidal
zonation of herbivorous gastropods.
