W. Reed

W. Reed is a faculty member in the Department of Biology at the University of Missouri–St. Louis. His research integrates behavioral ecology with physiological mechanisms, focusing on how hormonal regulation influences life-history traits and fitness outcomes in wild bird populations.

His primary research interests lie at the intersection of behavioral endocrinology and evolutionary ecology. Reed investigates how testosterone modulates trade-offs between survival and reproductive success, particularly in avian systems. His work contributes to understanding how physiological constraints shape life-history evolution and population dynamics.

Reed’s recent publication in The American Naturalist (2006) exemplifies his long-term experimental approach, using demographic modeling to assess how elevated testosterone affects male fitness in dark-eyed juncos. The study revealed complex interactions between hormone levels, mating success, and offspring viability, highlighting the nuanced roles of endocrine systems in ecological contexts.
