Meeting Abstract 17.5  Thursday, Jan. 3  Roost-making behavior and bite force of bats living inside active termite nests SANTANA, Sharlene E.*; DECHMANN, Dina K. N.; DUMONT, Elizabeth R.; UMass Amherst; Leibniz-Institute for Zoo and Wildlife Research; UMass Amherst ssantana@bio.umass.edu Most mammals are polygynous, often living in small groups in which one or a few males mate with […]

Meeting Abstract 17.1  Thursday, Jan. 3  Ontogeny of rhythmic chewing and masseter activity in a selenodont artiodactyl WILLIAMS, S.H.*; SIDOTE, J.V.; Ohio University, Athens; Ohio University, Athens willias7@ohio.edu Morphological maturation of the masticatory system in selenodont artiodactyls is a relatively slow process. In domesticated species, the full complement of postcanine teeth is not present until 3-5 years. […]

Meeting Abstract 17.5  Sunday, Jan. 4  Understanding regulation of adaptive changes in skeletal muscle physiology of Weddell seals: A proteomics approach CABLE, AE*; KANATOUS, SB; Colorado State University; Colorado State University amber.e.cable@gmail.com Weddell seals (Leptonychotes weddelli) are elite diving mammals that use aerobic respiration in their swimming muscles during prolonged periods of hypoxia. Upon cessation of weaning […]

Meeting Abstract 17.2  Sunday, Jan. 4  Temperature gradients in the dorsolongitudinal flight muscles of Manduca sexta may yield functional gradients. GEORGE, N.T.*; DANIEL, T.L.; Univ. of Washington, Seattle ntgeorge@u.washington.edu During muscle contraction, heat is produced as chemical energy is converted into mechanical work. Many large insects with active flight muscles use this byproduct to elevate flight muscle […]

Meeting Abstract 17.1  Sunday, Jan. 4  Low thermal dependence of elastically-powered movement in salamanders DEBAN, S.M.; Univ. South Florida sdeban@cas.usf.edu Biological springs in musculoskeletal systems provide a range of benefits to organisms including energy recovery, power amplification, improved force control, and expanded functional range of muscles. To test the hypothesis that, in addition, elastic recoil mechanisms extend […]

Meeting Abstract 17.3  Sunday, Jan. 4  Effects of temperature on dynamic properties of active and passive caterpillar muscle: Q10 less than 1? WOODS, W. A. Jr.*; TRIMMER, B. A. ; Tufts University; Tufts University william.woods@tufts.edu Caterpillars are soft-bodied terrestrial climbers that accomplish a wide variety of complex movements over a broad range of ambient temperatures using several […]

Meeting Abstract 17.4  Sunday, Jan. 4  Chameleons Maintain High-Performance Tongue Projection at Low Temperature ANDERSON, C.V.*; DEBAN, S.M.; University of South Florida; University of South Florida cvanders@mail.usf.edu The impact of environmental factors on the physiology of ectotherms such as lizards, for example, the effect of temperature on muscle contraction velocity, are known to constrain natural activity patterns. […]

Meeting Abstract 17.3  Monday, Jan. 4  REGULATION OF DEVELOPMENT BY CORTICOTROPIN RELEASING HORMONE IN DIRECT DEVELOPING FROG ELEUTHERODACTYLUS COQUI KULKARNI, Saurabh*; ELINSON, Richard; SINGAMSETTY, Shrikanth; BUCHHOLZ, Daniel; University of Cincinnati; Duquesne University; Duquesne University; University of Cincinnati kulkarsb@email.uc.edu Direct developing frogs lack a free-living larval period and hatch from the egg as a juvenile. Even under such […]

Meeting Abstract 17.5  Monday, Jan. 4  Environmental Effects on Drosophila Brain Development and Learning ROBERTS, S.P.*; WANG, X.; DE BELLE, J.S.; Central Michigan University; University of Nevada Las Vegas; University of Nevada Las Vegas stephen.roberts@cmich.edu Brain development and cognition are sensitive to environmental perturbations experienced by sub-adult organisms. However, little is known about how (A) multiple stressors […]
