Meeting Abstract 66.1 Monday, Jan. 6 08:00 New macrophysiological insights into old macroecological patterns: energetic constraints on geographic range size in mammals AGOSTA, SJ*; BERNARDO, J; Virginia Commonwealth University; Texas A&M University sagosta@vcu.edu Geographic range size varies over 12 orders of magnitude in mammals. At macroecological scales, variation in range size is related to body size, which […]

Lower thermal tolerance of larvae and adults of the introduced barnacle Megabalanus coccopoma implications for range limits
Meeting Abstract 66.2 Monday, Jan. 6 08:15 Lower thermal tolerance of larvae and adults of the introduced barnacle Megabalanus coccopoma: implications for range limits CRICKENBERGER, S*; WALTHER, K; MORAN, A; Clemson University; Clemson University; University of Hawaii at Manoa scricke@gmail.com As tropical species make their way into historically temperate climates, cold temperatures will likely set their range […]

FROST The red herring gene of insect cold tolerance
Meeting Abstract 66.5 Monday, Jan. 6 09:00 FROST: The red herring gene of insect cold tolerance? SINCLAIR, B.J.*; GRAETHER, S.P.; UDAKA, H.; Univ Western Ontario; Univ Guelph; Univ Western Ontario bsincla7@uwo.ca The gene FROST (Fst) is one of the most compelling candidates for a cold tolerance-related gene in Drosophila. Fst is upregulated in response to a brief […]
Using Allostasis as a Foundation for Modeling Studies
Meeting Abstract 65.5 Monday, Jan. 6 10:30 Using Allostasis as a Foundation for Modeling Studies ROMERO, LM*; FEFFERMAN, NH; Tufts University; Rutgers University michael.romero@tufts.edu Physiological stress is increasingly used in conservation as an index for at-risk populations. However, it is unclear how to “scale up” from individual stress responses to population-level impacts. Traditional models of stress, based […]
Stress and reproduction What underlies reproductive suppression when birds are brought into captivity
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.

Steroid Synthesis in the Brain
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 […]
Protective and Damaging Effects of Mediators of Stress and Adaptation
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 […]
Food, stress, and circulating testosterone cue integration by the testes, not the brain, in zebra finches (Taeniopygia guttata)
Meeting Abstract 65.2 Monday, Jan. 6 08:30 Food, stress, and circulating testosterone: cue integration by the testes, not the brain, in zebra finches (Taeniopygia guttata) LYNN, S.E.*; PERFITO, N.; GUARDADO, D.; BENTLEY, G.E.; College of Wooster; Univ. of California, Berkeley; Univ. of California, Berkeley; Univ. of California, Berkeley slynn@wooster.edu Ecologically relevant fasting stimulates glucocorticoid secretion and reduces […]
