SHEEHY III, C. M.*; LILLYWHITE, H. B.; Univ. of Florida, Gainesville; Univ. of Florida, Gainesville: Foraging Behaviors of Insular Cottonmouth Snakes Florida cottonmouth snakes (Agkistrodon piscivorus conanti) exhibit significant variation of foraging behavior on a single island at Cedar Keys, Florida. Snakes in this population characteristically remain beneath avian rookeries where colonial nesting birds drop […]

ENGESZER, RE*; ALBERICI DA BARBIANO, L; RYAN, MJ; PARICHY, DM; University of Washington, University of Texas at Austin; University of Texas at Austin; University of Washington ; University of Texas at Austin: An analysis of shoaling preference in the zebrafish, Danio rerio How social aggregations arise and persist is central to our understanding of evolution, […]
Yolk steroids regulate crypic back patterns in a lizard
Meeting Abstract 2.9 Jan. 4 Yolk steroids regulate crypic back patterns in a lizard LANCASTER, LT*; MCADAM, AG; WINGFIELD, JC; SINERVO, BR; Univ. of California, Santa Cruz; Michigan State Univ.; Univ. of Washington; Univ. of California, Santa Cruz lesley@biology.ucsc.edu We investigated the role of maternally derived yolk steroids in modulating back pattern elements in side-blotched lizards (Uta […]
Somatostatin Inhibits Hepatic Growth Hormone Sensitivity by Activating the MAPK Signaling Pathway
Meeting Abstract 2.6 Jan. 4 Somatostatin Inhibits Hepatic Growth Hormone Sensitivity by Activating the MAPK Signaling Pathway HAGEMEISTER, A.L.*; SHERIDAN, M.A.; North Dakota State Univ., Fargo Alison.Hagemeister@ndsu.edu Previously, we reported that somatostatins (SS) inhibit organismal growth by reducing hepatic growth hormone (GH) sensitivity and by inhibiting insulin-like growth factor-1 (IGF-I) production. In this study, we used hepatocytes […]
Sex and laboratory effects in second-to-fourth digit length ratios (2D4D) in green anole lizards
Meeting Abstract 2.3 Jan. 4 Sex and laboratory effects in second-to-fourth digit length ratios (2D4D) in green anole lizards CHANG, J.L.*; DOUGHTY, S.; WADE, J.; LOVERN, M.B.; University of Miami; Oklahoma State Univ.; Michigan State Univ.; Oklahoma State Univ. stynoski@bio.miami.edu Digit length ratios can show sexual dimorphism related to embryonic steroid exposure. The second-to-fourth digit-length ratio has […]
Post-prandial response of insulin, IGF-I, and IGFBPs in fasted coho salmon
Meeting Abstract 2.1 Jan. 4 Post-prandial response of insulin, IGF-I, and IGFBPs in fasted coho salmon. BECKMAN, B.R.*; SHIMIZU, M.; NOAA Fisheries; University of Hokkaido Brian.Beckman@NOAA.gov Insulin and insulin-like growth factor-I are peptide hormones that apparently arose from a common ancestral gene. Both IGF-I and insulin are important components of the endocrine growth regulation system. To better […]
Phenotypic Effects of Increased Yolk Corticosterone in Tree Lizards (Urosaurus ornatus)
Meeting Abstract 2.10 Jan. 4 Phenotypic Effects of Increased Yolk Corticosterone in Tree Lizards (Urosaurus ornatus) JOHNSTON, G.I.H.**; FRENCH, S.S.; MOORE, M.C.; Arizona State University; Arizona State University; Arizona State University gjohnston@asu.edu Maternal influences on offspring phenotype via non-genetic mechanisms is an area of recent interest, especially in egg-laying species. Hormones are a common yolk constituent in […]
Metabolic hormones directly regulate insulin-like growth factor-2 mRNA level in primary cultured salmon hepatocytes
Meeting Abstract 2.8 Jan. 4 Metabolic hormones directly regulate insulin-like growth factor-2 mRNA level in primary cultured salmon hepatocytes PIERCE, AL*; DICKEY, JT; SWANSON, P; DICKHOFF, WW; Univ Hawaii; Univ Washington; Nat Mar Fish Svc; Univ Washington piercea@hawaii.edu Insulin-like growth factors (IGF-1 and IGF-2) stimulate growth and development of vertebrates. Both IGFs are expressed widely; however, circulating […]
Leptin enhances growth and development under disease exposure in Xenopus laevis tadpoles
Meeting Abstract 2.7 Jan. 4 Leptin enhances growth and development under disease exposure in Xenopus laevis tadpoles HICKS-COURANT, Miranda L.*; CRESPI, Erica J.; Vassar College mihickscourant@vassar.edu Leptin is a cytokine hormone that is best known for regulating food intake, energy expenditure, and reproduction, but recent studies have shown that it also affects immune response in mammals. While […]
Evolutionary conservation of nuclear hormone receptor response elements thyroid hormone regulation of the basic transcription element binding protein 1 gene
Meeting Abstract 2.4 Jan. 4 Evolutionary conservation of nuclear hormone receptor response elements: thyroid hormone regulation of the basic transcription element binding protein 1 gene. DENVER, Robert/J*; WILLIAMSON, Keith/E; Univ. of Michigan; Univ. of Michigan rdenver@umich.edu Nuclear hormone receptors (NRs) regulate gene expression by binding to consensus hormone response elements (HREs). HREs may be located within the […]
