Professional Background & Research Interests:My research interests focus on the life history and ecology of fishes. My interests in fishes have always included an applied component, developed during 12 years of work at the Waterways Experiment Station (Vicksburg MS, U.S. Army Corps of Engineers), and later as an independent consultant. My applied has research concentrated on assessment of the effects of river regulatory practices (water diversions, dams, levees, channel alignment, etc.) on river ecosystems. Additional research interests allied to my stream work have included the ecology of riparian habitats, wetlands, impoundments and estuaries. In this research area, I am currently working on developing biotic inventories for streams and riparian areas within several north-central Massachusetts preserves. All of these interests are reflected in my appointment as a Research Fellow at the George Perkins Marsh Institute. My teaching at Clark has reflected both sets of interests, as I have taught courses ranging from Ecological Systems and Applied Ecology, to Introductory Biology and Biodiversity. In the spring of 2008 I will teach Ecology and Conservation Biology. Selected Publications:Baker, J.A., W.C. Cresko, D.C. Heins and S.A. Foster. 2005.

My early research centered on freshwater stream fishes of the southeastern U.S., but over the last 15 years it has broadened to include my current studies on the adaptive radiation of the stickleback. Life history traits such as offspring size, fecundity, age at reproduction, and patterns of senescence are features of organisms that are especially closely linked to fitness, and freshwater fishes provide outstanding opportunities to understand the relationships between environment and life history evolution. The post-glacial adaptive radiation of the threespine stickleback fish offers particularly unique insights. In addition to life-history traits, my work with threespine stickleback also includes studies on the evolution of anti-predator armoring and related morphological traits.
