Peripheral sensory pathways in the pond snail Lymnaea stagnalis
Meeting Abstract 3.6 Jan. 4 Peripheral sensory pathways in the pond snail Lymnaea stagnalis WYETH, R.C.*; CROLL, R.P.; Dalhousie University Russell.Wyeth@dal.ca Sensory systems are integral to the neural control of behavior. However, despite extensive neuroethological study of gastropod molluscs, there is only patchy understanding of their sensory pathways. For example, previous work has identified nitrergic chemosensory neurons, […]

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 […]
