Meeting Abstract 28.5  Monday, Jan. 4  Linking physiological traits across rocky intertidal communities through ecological genomics PLACE, S.P.; University of South Carolina splace@biol.sc.edu Along the Oregon coast, a host of ecological differences in rocky intertidal communities have been documented for two capes separated by less than 70 km. These differences are in large part attributable to oceanographic […]

Meeting Abstract 28.3  Monday, Jan. 4  Life in leaf boundary layers: how two millimeters of still air affects the performance and ecology of small insects WOODS, H. A.*; POTTER, K. A.; Univ. of Montana; Univ. of Arizona art.woods@mso.umt.edu An allometric claim: what we know about an animal’s environment scales to its body size with b > 1. […]

Meeting Abstract 28.4  Monday, Jan. 4  How Does Spatial Variation in Climate Cause Spatiotemporal Patterns in Lizard Energetics? POWERS, S.D.*; ANDERSON, R.A.; Western Washington University; Western Washington University seandpowers@gmail.com A lizard’s ability to be active and to acquire food for growth, storage, and reproduction is expected to be seasonally constrained by the complex, dynamic set of phenomena […]

E.; Univ. of California, Berkeley; Univ. of California, Berkeley; Univ. of Wyoming; Univ. of California, Berkeley msdevries@berkeley.edu The mantis shrimp species Neogonodactylus bredini (Stomatopoda) produces high accelerations and forces with […]

Meeting Abstract 28.2  Monday, Jan. 4  A glowing benthic animal is hard to find: A photographic and spectroscopic survey of bioluminescence on the deep-sea floor JOHNSEN, S.*; HADDOCK, S.H.D.; Duke University; Monterey Bay Aquarium and Research Institute sjohnsen@duke.edu Bioluminescence is nearly ubiquitous in marine pelagic species, particularly those of the open ocean. However, the extent of bioluminescence […]

Meeting Abstract 28.2  Wednesday, Jan. 5  The effects of betamethasone on myosin expression patterns of fetal Cavia porcellus hindlimb and ventilatory musculature SCHROEDER, J.R.*; PREHODA-WYERS, M.M.; DEAROLF, J.L.; Hendrix College schroederjr@hendrix.edu When pregnant women are likely to give birth prematurely, glucocorticoids are administered to accelerate the development of fetal organs. Studies indicate glucocorticoids switch the cell cycle […]

Meeting Abstract 28.3  Wednesday, Jan. 5  The Relative Contributions of Titin and Collagen to Passive Tension POWERS, KL*; MONROY, JA; GILMORE, LA; NISHIKAWA, KC; Northern Arizona University krysta.powers@nau.edu Passive tension in an intact muscle has been attributed primarily to titin and collagen. This study aims to quantify the relative contributions of titin and collagen to passive tension […]

Meeting Abstract 28.1  Wednesday, Jan. 5  Effects of glucocorticoid administration on the contractile properties of the fetal guinea pig diaphragm SCIORTINO, A.**; PREHODA-WYERS, M.M.; DEAROLF, J.L.; Hendrix College, Conway, AR sciortinoaa@hendrix.edu Glucocorticoids have been administrated to pregnant mothers at risk of preterm delivery in order to stimulate fetal lung development. The application of these steroids improves neonatal […]

Meeting Abstract 28.4  Wednesday, Jan. 5  Ca2+-activation of skeletal muscle: Not just the thin filament? MONROY, J.A.*; POWERS, K.L.; GILMORE, L.A.; UYENO, T.A.; NISHIKAWA, K.C.; Northern Arizona University Jenna.Monroy@nau.edu Titin, the largest known protein, contributes to muscle passive tension but its role in active muscle remains elusive. In this study, we investigated the effect of activation on […]
