Meeting Abstract 75-5  Monday, Jan. 6 09:00 – 09:15  Passive mechanical properties of crocodilian limb muscles correlate with in vivo function ARIAS, AA*; BALL, AM; AZIZI, E; University of California, Irvine adriena@uci.edu https://adrienarias.wordpress.com The passive mechanical properties (i.e. passive stiffness) of muscle have been shown to influence the region of the force-length (F-L) curve over which it […]

Meeting Abstract 75-3  Monday, Jan. 6 08:30 – 08:45  Osmotic engine drives shortening in passive skeletal muscle WOLD, ES*; ROBERTS, TJ; SLEBODA, DA; Brown University, Providence RI; Brown University, Providence RI; Brown University, Providence RI ethan_wold@brown.edu Skeletal muscle, like most biological tissues, is primarily made up of fluid. This fluid is rarely considered a mechanical component of […]

Meeting Abstract 75-6  Monday, Jan. 6 09:15 – 09:30  Mimicking the load-holding capabilities of muscle using electrostatic layer jamming NOEL, A*; NADLER, J; Georgia Tech Research Institute; Georgia Tech Research Institute alexis.noel@gtri.gatech.edu Biological muscles have the ability to quickly stiffen and hold large loads, two highly coveted traits for soft robotic actuators. Various techniques have been used […]

Meeting Abstract 75-1  Monday, Jan. 6 08:00 – 08:15  Construction and Deconstruction of Muscle Work Loops NGUYEN, KD*; VENKADESAN, M; Yale University; Yale University khoi.nguyen@yale.edu Muscles are actuators that exert forces to influence animal movement, but are also active, soft materials that exert forces in response to external perturbations. Rheology, the study of deformation of matter, uses […]

WANG, J.H*; CAIN, S.D.; LOHMANN, K.J.: The identification and characterization of magnetically sensitive neurons in Tritonia diomedea Numerous behavioral studies show that diverse organisms use the earth’s magnetic field for orientation and navigation. Despite over three decades of interest in this behavioral phenomenon, little is known about the neural mechanisms that underlie this ability. In […]

BOLES, L.C.*; LOHMANN, K.J.: The effects of attached magnets on the orientation of displaced spiny lobsters Many animals use the Earth�s magnetic field as a cue during orientation and navigation. However, relatively little is known about how these animals, particularly invertebrates, actually detect magnetic fields. Spiny lobsters, Panulirus argus have a magnetic compass sense and […]

CAIN, SD; BALTZLEY, MJ: The Distribution of Neurotransmitters Controlling the Foot Cilia of the Sea Slug Tritonia diomedea The nudibranch mollusc Tritonia diomedea, which is known to orient to water currents and the Earth’s magnetic field, primarily locomotes using ciliary action of cells that cover the surface of the foot. The activity of these cilia […]

WYETH, R.C.*; WILLOWS, A.O.D.: Field behavior of the nudibranch mollusc, Tritonia diomedea: a baseline for the neuroethology of orientation and navigation. Animals use a variety of senses to navigate through their environment. How do they integrate multiple senses to direct movement? The nudibranch Tritonia diomedea is an excellent candidate for investigating mechanisms of sensory integration […]

MCDONALD, M. Danielle; WALSH, Patrick J.; Rosenstiel School and Marine and Atmospheric Science, University of Miami; Rosenstiel School of Marine and Atmospheric Science, University of Miami: The role of glucocorticoids and 5-HT2-like receptors in branchial urea excretion of the gulf toadfish, Opsanus beta The gulf toadfish, Opsanus beta, has a unique pulsatile urea excretion mechanism […]

GROSELL, M.; TAYLOR, J.; University of Miami: Intestinal bicarbonate secretion is a novel aspect of marine teleost osmoregulation Drinking and intestinal water absorption forms a critical component of marine teleost fish osmoregulation. Ingested seawater is desalinized in the esophagus prior to entering the intestine where active absorption of Na+ and Cl– drives water absorption. In […]
