Meeting Abstract P1.72  Monday, Jan. 4  Regulation of Metamorphosis by Mechanosensory Stimulation and Catecholamines in a Gastropod PIRES, A.*; LEWIS, E.L.; Dickinson College; Dickinson College pires@dickinson.edu Larvae of many marine invertebrates metamorphose in response to chemical cues in the environment. However, the chemosensory induction of metamorphosis may be modulated by other sensory experience, or by the biochemical […]

Meeting Abstract P1.50  Monday, Jan. 4  Reduced herbivory by Caribbean sea urchins in response to chemical cues of a known predator PARISH, E.R.*; TURNER, T.; Univ. of the Virgin Islands eddieparish@gmail.com Non-consumptive, indirect effects can contribute to trophic cascades as well as to changes in prey species morphology, yet many ecological studies only consider direct consequences of […]

Meeting Abstract P1.173  Monday, Jan. 4  Rapid Horizontal vs. Vertical Locomotion in the Mouse Lemur (Microcebus murinus) O’NEILL, M*; HANNA, J; Stony Brook University School of Medicine; West Virginia College of Osteopathic Medicine matthew.oneill@stonybrook.edu Primates use both the ground and trees for traveling, feeding and escaping from predators. Their musculoskeletal systems must meet the competing demands for […]

Meeting Abstract P1.86  Monday, Jan. 4  Rainbow Trout Possess Two Hormone Sensitive Lipase-Encoding mRNAs that are Differentially Expressed and Differentially Regulated by Fasting KITTILSON, J.D.; REINDL, K.M.; SHERIDAN, M.A.*; North Dakota State Univ., Fargo mark.sheridan@ndsu.edu Teleost fish store lipids among several tissues primarily as triacylglycerol (TG). Upon metabolic demand, stored TGs are hydrolyzed by hormone-sensitive lipase (HSL). […]

Meeting Abstract P1.135  Monday, Jan. 4  RNAi mediated disruption of ecdysteroid signaling during limb regeneration in the fiddler crab, Uca pugilator. DAS, S.*; HOPKINS, P.M.; KHAMBADAKONE, D.; DURICA, D.S.; Univ. of Oklahoma; Univ. of Oklahoma; Univ. of Oklahoma; Univ. of Oklahoma sunetra.das-1@ou.edu Growth, molting, limb regeneration and reproduction in crustaceans are regulated by arthropod steroid hormones, ecdysteroids. […]

Meeting Abstract P1.61  Monday, Jan. 4  Protein expression of genes that may be involved in initiating and developing the secondary dentition in mammals ARMFIELD, Brooke A. *; THEWISSEN, J.G.M.; VINYARD, Christopher J.; Department of Anatomy and Neurobiology, Northeastern Ohio Universities Colleges of Medicine and Kent State Biomedical Science; Rootstown, Ohio. bgarner@kent.edu Limited tooth replacement is a defining […]

Meeting Abstract P1.127  Monday, Jan. 4  Progesterone metabolites, “xenobiotic-sensing” nuclear receptors, and the metabolism of maternal steroids PAITZ, RT*; BOWDEN, RM; Illinois State University; Illinois State University rpaitz@ilstu.edu During development, embryos utilize steroid signals to direct sexual differentiation of tissues necessary for reproduction. Modulation of these signals by exogenous substances (both natural and synthetic) frequently produces phenotypic […]

Meeting Abstract P1.149  Monday, Jan. 4  Probing the evolutionary biomechanics of elastic energy storage in mantis shrimp ROSARIO, M. V.*; TAYLOR, J. R. A.; PATEK, S. N.; Univ. of California, Berkeley; Univ. of California, Berkeley; Univ. of Massachusetts, Amherst michaelvrosario@gmail.com Structural and biomechanical variation in elastic energy storage mechanisms is fundamental to the rich evolutionary diversity of […]

Meeting Abstract P1.55  Monday, Jan. 4  Prey choice in snakes may be influenced by temperature COBB, Vincent*; MASSEY, Diane; Middle Tennessee State University; Brock University vcobb@mtsu.edu Effectively distinguishing appropriate prey is a basic yet vital ability of all predators. For snakes, prey differentiation is primarily conducted by chemoreception when prey odors are transferred from the tongue to […]

Meeting Abstract P1.38  Monday, Jan. 4  Prenatal steroids: do they affect the development of the guinea pig rectus thoracis muscle? CHUGHTAI, A.**; BREWINGTON, A.K.; PREHODA-WYERS, M.M.; DEAROLF, J.L.; Hendrix College, Conway, AR chughtaiaa@hendrix.edu Glucocorticoids are used to accelerate the lung development of premature babies. The effects of glucocorticoids on breathing muscles are unknown, however. To determine the […]
