Biography

Power earned her Ph.D. in zoology from the University of Washington^[4] in 1981 and has been professor in the Department of Integrative Biology at the University of California Berkeley since 1987.^[4] She has also been the Faculty Director of the Angelo Coast Range Reserve^[6] in Mendocino County^[4] since 1989.

Professional work

Power's research on river food web ecology, community and landscape ecology has influenced theory on the importance of species interaction in food webs and of food webs in ecosystem functioning. Her long-term research has examined how species influence changes in food webs, how energy flows among ecosystems, and how species interactions vary in different environmental regimes, with relevance to Biogeomorphology and food web alterations.^[7]

Power's study of armored catfish was an early (1981) demonstration that ideal free distribution could be achieved by foragers in the wild. Power has studied river food webs in Panama, Oklahoma priaries, the Ozarks, and the Eel River of northwestern California.^[7]
