Meeting Abstract 57-7 Sunday, Jan. 5 11:45 – 12:00 To each their own? Meta-analysis of evidence of optimality of endocrine phenotypes BONIER, F*; COX, RM; Queen’s University; University of Virginia bonierf@queensu.ca http://post.queensu.ca/~bonierf/ Rosemary Knapp’s research contributions emphasize the importance of considering individual life history stage and strategy when seeking to understand endocrine traits. This perspective has been […]

Meeting Abstract 57-4 Sunday, Jan. 5 11:00 – 11:15 Onset and maintenance of male-typical parenting behavior during protogynous sex change PRADHAN, DS*; GROBER, MS; WHITE, KJ; Idaho State University, Pocatello, ID; Georgia State University, Atlanta, GA; Idaho State University, Pocatello, ID praddeva@isu.edu In species that change sex based on social cues, behavioral sex change is rapid and […]
Evolution of alternative behavioral phenotypes A story of genes and bird brains
Meeting Abstract 57-2 Sunday, Jan. 5 10:30 – 10:45 Evolution of alternative behavioral phenotypes: A story of genes and bird brains MANEY, DL; Emory University dmaney@emory.edu http://birdbrainlab.org Disruptive natural selection can drive the evolution of alternative phenotypes, or “morphs”, within one or both sexes. The morphs, so named because they differ with respect to a morphological trait […]
Evidence for Monoamines as Neurochemical Substrates Underlying Alternative Reproductive Tactics
Meeting Abstract 57-6 Sunday, Jan. 5 11:30 – 11:45 Evidence for Monoamines as Neurochemical Substrates Underlying Alternative Reproductive Tactics FORLANO, PM; CUNY Brooklyn College; CUNY Graduate Center pforlano@brooklyn.cuny.edu https://forlanolab.com/ Species that exhibit alternative male reproductive tactics (ARTs) offer an outstanding opportunity to explore the neural and hormonal mechanisms that underlie often extreme divergence in brain and behavior […]

Alternative strategies and the dynamism of color
Meeting Abstract 57-3 Sunday, Jan. 5 10:45 – 11:00 Alternative strategies and the dynamism of color THAKER, M*; BATABYAL, A; AMDEKAR, M; Indian Institute of Science, Bangalore, India mthaker@iisc.ac.in Alternative social strategies in lizards are often correlated with distinct color forms that are fixed upon development. In the Indian rock agama, Psammophilus dorsalis, dynamic physiological color changes […]
The Role of Corticosterone and the Effects of its Inhibition During the Development of Migratory Condition in Dark-eyed Juncos
HOLBERTON,R.*; WILSON,C.M.; SIMS,C.; CASH, W.B.: The Role of Corticosterone and the Effects of its Inhibition During the Development of Migratory Condition in Dark-eyed Juncos. To understand corticosterone’s role in the development of migratory feeding and fattening, dexamethasone (DXM) was used to inhibit an increase in baseline corticosterone often observed during migration. Dark-eyed juncos (Junco hyemalis) […]
The Endocrine Basis for Trade-offs between Immediate Survival and Reproductive Success in Arctic- and Temperate-breeding Yellow Warblers
WILSON, C.M.*; HOLBERTON, R.L.: The Endocrine Basis for Trade-offs between Immediate Survival and Reproductive Success in Arctic- and Temperate-breeding Yellow Warblers While temperate breeding birds can renest or produce more than one successful clutch each year, Arctic-breeders are unlikely to raise more than one clutch annually due to shorter breeding seasons and unpredictable weather. Despite […]
Seasonal differences in the response of corticosterone and nocturnal torpor to energy challenge in rufous hummingbirds
HIEBERT, S.M.*; SALVANTE, K.; RAMENOFSKY, M.; WINGFIELD, J.C.: Seasonal differences in the response of corticosterone and nocturnal torpor to energy challenge in rufous hummingbirds The energy balance of captive rufous hummingbirds (Selasphorus rufus) was challenged during the autumn migratory season and during the late winter prebasic molt by diluting the artificial nectar on which the […]
