Meeting Abstract 65.5  Friday, Jan. 6  Comparative Species Delimitation and Patterns of Cryptic Diversity in an Island Radiation of Fossorial Lizards SILER, CD; University of Kansas camsiler@ku.edu The transition from quadrapedal to limbless body plans has occurred repeatedly in numerous independent lineages of squamates. However, only four genera of lizards possess both fully limbed and limbless species. […]

Meeting Abstract 65.1  Friday, Jan. 6  A New Species of Hemidactylus Gecko Endemic to the Gulf of Guinea: A Story of Transoceanic Colonization Events MILLER, EC*; DREWES, RC; University of California, San Diego; California Academy of Sciences ecmiller@ucsd.edu The Gulf of Guinea islands São Tomé and Príncipe are home to a poorly-known endemic herpetofauna. Native and non-native […]

Meeting Abstract 65.2  Friday, Jan. 6  A 500-locus phylogenomic study of ray-finned fishes ALFARO, ME*; FAIRCLOTH, B; SORENSON, L; CHANG, J; SANTINI, F; UCLA; UCLA; UCLA; UCLA; UCLA michaelalfaro@ucla.edu Genomic approaches have helped resolve some of higher-level relationships on the fish tree of life. One key challenge that remains is to create phylogenomic techniques that easily, efficiently, […]

Meeting Abstract 65.5  Saturday, Jan. 5  Stop on Red: Neophobia and corticosterone in house sparrows (Passer domesticus) COOPER, L/N*; ROSS, A/E; FOLTZ, S/L; MOORE, I/T; DAVIS , J/E; Radford University; Virginia Tech; Virginia Tech; Virginia Tech; Radford University lncooper@radford.edu When confronted with novel stimuli, animals must evaluate both the stimulus itself as well as their surrounding environment. […]

Meeting Abstract 65.4  Saturday, Jan. 5  Seasonal variation in intracellular glucocorticoid receptor binding in the immune tissues of a wild bird LATTIN, C. R.*; ROMERO, L. M.; Tufts University; Tufts University christine.lattin@tufts.edu Glucocorticoids such as corticosterone (CORT) help wild animals regulate their metabolism and cope with environmental stressors, but they can also have immunosuppressive effects. Nelson and […]

Meeting Abstract 65.2  Saturday, Jan. 5  Real-time measurement of hippocampal corticosterone in a songbird RENSEL, M.A.*; KOSARUSSAVADI, S.; SCHLINGER, B.A.; Univ. of California, Los Angeles; Univ. of California, Los Angeles; Univ. of California, Los Angeles mrensel@ucla.edu Traditional models of steroid hormone action assume release from distinct endocrine glands into the bloodstream. However, recent studies indicate that tissues […]

Meeting Abstract 65.6  Saturday, Jan. 5  Long-term elevation of indicators of physiological stress in captive garter snakes SPARKMAN, AM*; PALACIOS, MG; BRONIKOWSKI, AM; Westmont College, California; National Council for Scientific and Technologic Research, Argentina; Iowa State University, Iowa sparkman@westmont.edu The physiological response to captive stress varies among species, with some adapting quickly to captive environments, but others […]

Meeting Abstract 65.1  Saturday, Jan. 5  Endocannabinoid regulation of glucocorticoids �” its for the birds DICKENS, M.J.*; BENTLEY, G.E.; Univ. of California, Berkeley; Univ. of California, Berkeley m.dickens@berkeley.edu Endocrine regulation of corticosterone (CORT) release during the stress response is well described in wild birds. Neural mechanisms impinging upon this endocrine system and regulating it seasonally are less […]

Meeting Abstract 65.3  Saturday, Jan. 5  Anticipatory Stress, Territoriality and Hunting in Wild Chimpanzees SOBOLEWSKI, ME*; BROWN, JL; MITANI, JC; University of Michigan mesobole@umich.edu Territoriality and hunting are energetically and psychologically demanding aspects of male chimpanzee behavior. The stress response allows an individual to quickly alter its physiological and behavioral profile to successfully navigate such behaviors. The […]

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 […]
