Meeting Abstract 104.4  Thursday, Jan. 7  Characterization of the Bacterial Properties that Impair Respiration in the Atlantic Blue Crab, Callinectes sapidus JOHNSON, N.G.*; BURNETT, L.E.; BURNETT, K.G.; College of Charleston; College of Charleston; College of Charleston ngjohnso@edisto.cofc.edu In the blue crab Callinectes sapidus, injection with the bacterial pathogen Vibrio campbellii causes a decrease in oxygen consumption. Histological […]

Meeting Abstract 104.1  Thursday, Jan. 7  Carbonic anhydrase activity in gill and mantle tissues from Doryteuthis pealeii NYACK, A.C.*; HENRY, R.P.; SEIBEL, B.A.; University of Rhode Island; Auburn University; University of Rhode Island alnyack@gmail.com The enzyme carbonic anhydrase (CA) rapidly catalyzes the reversible reaction of CO2 to HCO3– and H+ both at sites of production (tissues) and […]

Meeting Abstract 103.1  Thursday, Jan. 7  How do humans stabilize running? QIAO, Mu; JINDRICH, Devin L*; Arizona State University; Arizona State University devin.jindrich@asu.edu The control strategies used to stabilize running are not well understood. However legged robots are capable of stable running based on three simple control rules: maintain running speed, height, and pitch angle. We tested […]

Meeting Abstract 103.5  Thursday, Jan. 7  Effects of CoM Position on Forelimb and Hindlimb Mechanics during Incline and Decline Trotting LEE, D.V.; University of Nevada Las Vegas dvlee@mac.com Quadrupedal running on inclines and declines presents the mechanical challenge of balancing pitch moments about the center of mass (CoM) while maintaining a steady velocity in the direction of […]

Meeting Abstract 103.2  Thursday, Jan. 7  Biomechanical Problems of Load Transport: How Grass-Cutting Ants Avoid Falling Over MOLL, K*; FEDERLE, W; Cambridge University, UK km498@cam.ac.uk The influence of loads on running locomotion has been studied in many arthropods. However, most studies have only considered the effect of load mass but not mechanical problems associated with load shape. […]

Meeting Abstract 103.6  Thursday, Jan. 7  Adding Inertia and Mass to Test Stability Predictions in Rapid Running Insects MOORE, T.*; BURDEN, S.; REVZEN, S.; FULL, R.J.; Univ. of California, Berkeley taliayuki@berkeley.edu A spring-mass model for the horizontal plane dynamics of sprawled running animals (Lateral Leg Spring Model) predicts that added inertia reduces stability and increases the time […]

Meeting Abstract 103.4  Thursday, Jan. 7  A static model predicts the relationship between force and lean angle during dynamic turning in goats MORENO, C.A.*; BIEWENER, A.A.; Harvard University cmoreno@oeb.harvard.edu Evasive maneuvers and turning behaviors are critical components of a terrestrial animal’s locomotor repertoire. To investigate the mechanics of such non-steady behaviors, we collected ground reaction forces (GRFs) […]

Meeting Abstract 102.3  Thursday, Jan. 7  What makes a great footballer? Trade-offs between athleticism and skill in human performance WILSON, R S*; SMITH, M D; Univ. of Queensland, Australia; Univ. of Queensland, Australia r.wilson@uq.edu.au Animal performance during critical behaviours such as predator-escape, prey-capture and fighting is determined by a complex assortment of underlying traits. Maximal physical capacity […]

Meeting Abstract 102.6  Thursday, Jan. 7  I can score more than you! Investigating the importance of skill on whole organism performance in a complex environment DAVID, Gwendolyn*; ORTIZ-BARRIENTOS, Daniel; SMITH, Michelle; WILSON, Robbie; Univ. of Queensland, Brisbane g.david@uq.edu.au Skill, the ability to effectively execute a learned motor task, plays a fundamental role in the ecology and evolution […]

Meeting Abstract 102.2  Thursday, Jan. 7  High-Speed Horizontal to Vertical Transitions in Running Cockroaches Reveals a Principle of Robustness JAYARAM, K.*; MONGEAU, J. M.; MCRAE, B.; FULL, R.J.; Univ. of California, Berkeley; Univ. of California, Berkeley; Univ. of California, Berkeley; Univ. of California, Berkeley kaushikj@berkeley.edu We marvel at the gracefulness of large animals as they maneuver over […]
