Madeleine Naylor, a Master's student in the Grindstaff lab, won second place from the Division of Animal Behavior for her poster presentation at the Society of Integrative and Comparative Biology National Conference in Portland, Oregon. Madeleine's research investigates how an environmental endocrine disrupting chemical, 17alpha-Ethinylestradiol (EE2), influences courtship behavior, parental care and reproductive success in Zebra Finches (Taeniopygia guttata). Her research is novel because she is measuring changes in adult behavior in response to environmental EE2 exposure and how these behavioral changes impact overall reproductive success of a breeding pair, as opposed to the more commonly studied physiological effects of EE2 on development. Her poster presented recent results indicating that EE2 decreases male zebra finch courtship behavior and increases the likelihood of pairs showing bonding behavior more quickly than pairs with control males. Congratulations Madeleine!
