Meeting Abstract S8.1-1 Monday, Jan. 6 08:00 Developmental and maternal effects on behavioral plasticity MATEO, Jill M.; The University of Chicago jmateo@uchicago.edu Social, hormonal and genetic processes interact reciprocally, and differentially affect behavior depending on ecological and social contexts. Multiple developmental processes would be expected when individual differences are favored either between or within environments. Parental effects […]

The need for speed Neuroendocrine regulation of socially controlled sex change
Meeting Abstract S8.9 Tuesday, Jan. 6 14:00 The need for speed: Neuroendocrine regulation of socially controlled sex change GODWIN, J*; LAMM, MA; LIU, H; GEMMELL, N; North Carolina State University; North Carolina State University; University of Otago; University of Otago John_Godwin@ncsu.edu http://godwin.wordpress.ncsu.edu/ Socially controlled functional sex change in fishes is a dramatic example of adaptive reproductive plasticity. […]
Steroid-opioid interactions and rapid changes in the motivation to communicate
Meeting Abstract S8.6 Tuesday, Jan. 6 11:00 Steroid-opioid interactions and rapid changes in the motivation to communicate RITERS, LV; University of Wisconsin–Madison LVRiters@wisc.edu http://zoology.wisc.edu/faculty/Rit/Rit.html Vocal signals convey information about an individual’s motivational and social status. As circumstances change, individuals adjust vocal behavior accordingly. It is common for individuals that gain a territory to immediately increase the production […]
Social transitions cause rapid behavioral and neuroendocrine changes
Meeting Abstract S8.8 Tuesday, Jan. 6 13:30 Social transitions cause rapid behavioral and neuroendocrine changes MARUSKA, K.P.; Louisiana State Univ. kmaruska@lsu.edu http://www.kmaruska.biology.lsu.edu/ In species that form dominance hierarchies, there are often opportunities for low-ranking individuals to challenge high-ranking ones, resulting in a rise or fall in social rank. How does an animal detect, process and then respond […]
Sex, stress, and rapid estradiol changes in the male brain
Meeting Abstract S8.5 Tuesday, Jan. 6 10:30 Sex, stress, and rapid estradiol changes in the male brain DICKENS, Molly J.; Univ. of California, Berkeley m.dickens@berkeley.edu Envisioning the stereotype of human masculinity – chest puffing, competing, boasting of sexual prowess – we may be inclined to attribute such behavior to Testosterone. However, studies in a range of vertebrate […]
Rapid effects of steroids on the brain and social behavior of songbirds
Meeting Abstract S8.7 Tuesday, Jan. 6 11:30 Rapid effects of steroids on the brain and social behavior of songbirds SOMA, KK; Univ. 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 signalling […]
Neuroendocrine dynamics of reproductive hormones GnRH-I and GnIH in response to seasonal, social, and rapid changes in behavior
Meeting Abstract S8.11 Tuesday, Jan. 6 15:00 Neuroendocrine dynamics of reproductive hormones GnRH-I and GnIH in response to seasonal, social, and rapid changes in behavior CALISI, RM; Barnard College, Columbia University rcalisi@barnard.edu How does the vertebrate brain regulate sexual and reproductive behaviors? Gonadotropin-releasing hormone (GnRH-I) and gonadotropin-inhibitory hormone (GnIH) are key hypothalamic hormones that mediate vertebrate reproductive […]
Estrogen Receptor Alpha A Mediator of Life History Trade-offs
Meeting Abstract S8.10 Tuesday, Jan. 6 14:30 Estrogen Receptor Alpha: A Mediator of Life History Trade-offs? MANEY, Donna L.*; ZINZOW-KRAMER, Wendy M.; Emory University; Emory University dmaney@emory.edu http://www.birdbrainlab.org In many vertebrates, tradeoffs between competitive and parental strategies are well-understood to be mediated by sex steroids. Disruptive selection leading to alternative behavioral strategies may thus act on the […]
Buttons and Glue novel forms of estrogen provision
Meeting Abstract S8.1 Tuesday, Jan. 6 08:00 Buttons and Glue: novel forms of estrogen provision. SALDANHA, CJ; The American University saldanha@american.edu Estrogens (E) affect vertebrate brain and behavior throughout the lifespan. Given the diversity of E-dependent behaviors, targets, and sources, the spatial and temporal precision of E-delivery is of considerable interest. In the songbird, while aromatase is […]
An integrative look at acute steroid signaling in the nervous system
Meeting Abstract S8.2 Tuesday, Jan. 6 08:30 An integrative look at acute steroid signaling in the nervous system REMAGE-HEALEY, Luke; University of Massachusetts healey@cns.umass.edu The central nervous system governs interactions between organisms and their environments. Traditionally, the brain has been viewed as a central integrator of circulating hormones, external cues, and internal states. It is clear now […]
