Meeting Abstract 132.2 Monday, Jan. 7 The Effects of Chronic Cortisol on Appetite in Tilapia Oreochromis mossambicus BRASCHAYKO, E.B.*; RILEY, L.G.; Fresno State Univ.; Fresno State Univ. ebrasch45@mail.fresnostate.edu Stress in fish has been shown to impair growth, reproduction, immune function and overall health. Stress is managed along the hypothalamic-pituitary-interrenal axis resulting in the release of cortisol. In […]

Food supplementation of Florida Scrub-Jay (Aphelocoma coerulescens) nestlings long-term effects on hypothalamic-pituitary-adrenal axis responsiveness
Meeting Abstract 132.1 Monday, Jan. 7 Food supplementation of Florida Scrub-Jay (Aphelocoma coerulescens) nestlings: long-term effects on hypothalamic-pituitary-adrenal axis responsiveness SMALL, TW*; BRIDGE, ES; SCHOECH, SJ; University of Memphis; University of Oklahoma; University of Memphis twsmall@memphis.edu In a wide variety of animals, plasma glucocorticoid levels rapidly increase in response to a stressor. In Florida Scrub-Jays (Aphelocoma coerulescens), […]
Energetic constraints and parental care is corticosterone an important mediator of incubation behavior in a precocial bird
Meeting Abstract 132.4 Monday, Jan. 7 Energetic constraints and parental care: is corticosterone an important mediator of incubation behavior in a precocial bird? DURANT, SE*; HOPKINS, WA; HEPP, GR; ROMERO, LM; Tufts Univ; Virginia Tech; Auburn Univ sarah.durant@tufts.edu Suppression of the adrenocortical response (e.g., corticosterone release) to an acute stressor is a physiological adjustment thought to decrease […]
Effects of supplemental food and corticosterone treatment on begging and feeding behavior in Florida Scrub-Jays (Aphelocoma coerulescens)
Meeting Abstract 132.5 Monday, Jan. 7 Effects of supplemental food and corticosterone treatment on begging and feeding behavior in Florida Scrub-Jays (Aphelocoma coerulescens) ELDERBROCK, EK*; SMALL, TW; SCHOECH, SJ; University of Memphis; University of Memphis; University of Memphis kldrbrck@memphis.edu Begging is believed to communicate an honest signal of a nestling’s nutritional needs. When a nestling requires more […]
Direct Effects of Cortisol on Appetite Regulation in the Brain of Tilapia, Oreochromis mossambicus
Meeting Abstract 132.3 Monday, Jan. 7 Direct Effects of Cortisol on Appetite Regulation in the Brain of Tilapia, Oreochromis mossambicus DUNCAN , C.A.**; RILEY, L.G.; Fresno State Univ.; Fresno State Univ. cduncan@csufresno.edu Food intake in vertebrates is under the regulation of appetite stimulating (e.g. neuropeptide Y, ghrelin) and appetite inhibiting (e.g. corticotropin-releasing hormone) signals in the brain. […]
Body condition modulates responses to capture stress and exogenous corticosterone in female red-sided garter snakes
Meeting Abstract 132.6 Monday, Jan. 7 Body condition modulates responses to capture stress and exogenous corticosterone in female red-sided garter snakes. DAYGER, CA*; CEASE, AJ; LUTTERSCHMIDT, DI; Portland State Univ, OR; Univ of Sydney, Australia; Portland State Univ, OR cdayger@pdx.edu Many studies have examined the role of corticosterone (CORT) in male reproduction, but relatively little is known […]
Sensorimotor interactions in mammalian feeding
Meeting Abstract 131.6 Monday, Jan. 7 Sensorimotor interactions in mammalian feeding HOLMAN, S.D.; GERMAN, R.Z.*; Johns Hopkins University; Johns Hopkins University rz.german@jhmi.edu The mammalian swallow is considered distinct from oral processing (transport and mastication), involving separate sensorimotor pathways and distinct peripheral sensory nerves. We tested the hypothesis that anterior, oral sensation impacts pharyngeal function by selectively removing […]
Optomotor flight control of hawkmoths in the context of their flight dynamics
Meeting Abstract 131.2 Monday, Jan. 7 Optomotor flight control of hawkmoths in the context of their flight dynamics. MULLER, T.*; WINDSOR, S.P.; TAYLOR, G.K.; University of Oxford, UK tonya.muller@zoo.ox.ac.uk The sensorimotor systems involved in controlling an insect’s flight are tightly coupled with its flight dynamics. The properties of the flight control system must therefore be interpreted in […]
Emergence of a Neuromechanical Phase Lag in a Resistive Force Dominated Medium
Meeting Abstract 131.4 Monday, Jan. 7 Emergence of a Neuromechanical Phase Lag in a Resistive Force Dominated Medium DING, Y*; SHARPE, S.S.; GOLDMAN, D.I.; Georgia Tech; Georgia Tech; Georgia Tech dingyang@gatech.edu Undulatory locomotion is a common gait used by organisms in fluids, on land, andeven within sand. This mode of locomotion relies on propagation of a traveling […]
Differential limb function during locomotion on the level and over obstacles in the tarantula
