Ecology and Evolutionary Biology
The Department of Ecology and Evolutionary Biology (EEB) has a broad but unified mission in teaching and research: broad in that the interests of the faculty span many levels of organization encompassing genes, genotypes, phenotypes, populations, communities, and ecosystems; and unified in that each of these levels interacts with all of the others. Detailed appreciation of the processes operating at all levels of organization is fundamental to ecological or evolutionary understanding.

(University of Chicago Press, 1995-8)In many organisms, photoperiod and temperature are thought to be the most significant token cues for seasonally timed life history events, including diapause in arthropods. A common pattern in many species of terrestrial ...
(University of Chicago, 1984-6)Diaptomus sanguineus, a small freshwater copepod, avoids periods of intense fish predation by producing diapausing eggs. We developed a computer simulation of the copepod's life history and used it to compete populations ...
Species-specific Daphnia phenotypes: a history of industrial pollution and pelagic ecosystem response (Ecological Society of America, 2005-7)Phenotypic differences among species, even closely related species, may translate into distinct effects on ecosystem dynamics. In lakes, the generalist grazer genus Daphnia often has marked effects on the abundance of ...
(University of Chicago, 1994-3)Population genetics theory suggests that temporally fluctuating selection on pheno- types can act to maintain genetic variance only under very restrictive conditions. However, this conclusion is based on models with discrete ...
(Ecological Society of America, 2013-4)We explore how adding complexity to a typical predator-prey interaction affects temporal dynamics. Intraguild predation webs contain competition, predation, and omnivory in a system of three species where theory and empirical ...
