Meeting Abstract 65.1  Monday, Jan. 6 08:00  Stress and reproduction: What underlies reproductive suppression when birds are brought into captivity? DICKENS, M. J. ; BENTLEY, G. E. *; Univ. of California, Berkeley; Univ. of California, Berkeley m.dickens@berkeley.edu Intersecting research topics that John Wingfield pioneered, our study aimed to describe mechanisms underlying reproductive suppression in captive wild birds.

Meeting Abstract 65.3  Monday, Jan. 6 09:00  Steroid Synthesis in the Brain SOMA, K.K.; University of British Columbia ksoma@psych.ubc.ca Endocrinologists have traditionally focused on circulating hormone levels. In the case of steroid hormones, circulating steroids can be locally metabolized within the brain to either more active or less active signaling molecules. Furthermore, the brain can synthesize sex […]

Meeting Abstract 65.7  Monday, Jan. 6 11:30  Protective and Damaging Effects of Mediators of Stress and Adaptation MCEWEN, B.S. ; The Rockefeller University mcewen@rockefeller.edu An ever-changing environment requires an organism to adapt via a process called “allostasis” using the neuroendocrine, autonomic, immune and metabolic systems that interact with each other and function in a non-linear manner. The […]

Meeting Abstract 65.6  Monday, Jan. 6 11:00  Endocrinology of Avian Social Behavior ADKINS-REGAN, E; Cornell University er12@cornell.edu John Wingfield’s contributions to our current understanding of avian biology are vast and diverse. This tribute will begin by exploring the links between his research ideas and the work of the members of the Adkins-Regan lab. Next, the importance and […]

Meeting Abstract 65.4  Monday, Jan. 6 09:30  Behavioural neuroendocrinology in free-living wild Arctic breeding song birds: tales from the tundra… MEDDLE, SL; The Roslin Institutte, University of Edinburgh simone.meddle@roslin.ed.ac.uk Investigations into the neural mechanisms underlying complex male aggressive and reproductive behaviour in free-living wild birds are important as they provide a necessary compliment to captive studies; particularly […]
