Mary Eleanor Power is Professor of the Graduate School in the Department of Integrative Biology at the University of California, Berkeley.

She holds an honorary doctorate from Umeå University, Sweden, and is a recipient of the G. Evelyn Hutchinson Award of the Association for the Sciences of Limnology and Oceanography (formerly known as the American Society of Limnology and Oceanography (2005)), and the Kempe Award for Distinguished Ecologists (2004).

[4] Power and her work are featured prominently in the documentary film, The Serengeti Rules, which was released in 2018.

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.
