Teresa Dzieweczynski, Ph.D., associate professor in the Department of Psychology, published an article in the December 2017 issue of the Journal of Experimental Marine Biology and Ecology.

The article, “Sex and dose-dependent effects of an estrogen mimic on boldness in threespine stickleback, Gasterosteus aculeatus, from an anadromous population,” was co-authored by undergraduate student Nicole Greaney (Ocean Science and Marine Affairs ’17). It is Greaney’s fourth publication while at UNE.

This study is one of the first to examine the effects of inadvertent pharmaceutical exposure on behavior in a marine fish. Dzieweczynski and Greaney found that both the amount of estrogen mimic to which an individual was exposed and the sex of the individual exposed matter when determining the level of threat that exposure poses on fitness-related behavior in this species.

This research was made possible through a mini-grant from the Office of Research and Scholarship and through space and support from the Marine Science Center. This work is part of the Dzieweczynski lab’s ongoing research into the effects of pharmaceuticals and personal care product exposure on fish living in the Saco River and nearby estuaries.
