Meeting Abstract 49.4  Saturday, Jan. 5  Terrestrial jumping in the mangrove killifish Kryptolebias marmoratus PACE, C.; GIBB, A.C.*; ECKEL, J.; Northern Arizona University; Northern Arizona University; Northern Arizona University alice.gibb@nau.edu The amphibious mangrove killifish (Kryptolebias marmoratus) exhibits terrestrial jumping (or leaping); however, the mechanism that generates this behavior is undescribed. We address two questions about this behavior: […]

Meeting Abstract 49.5  Saturday, Jan. 5  Swimming spines of sharks PORTER, ME*; ROQUE, CM; SUMMERS, AP; University of California, Irvine; University of California, Irvine; University of California, Irvine porterm@uci.edu Maneuverability is a characteristic of locomotion that is difficult to assess, and can be measured as the turning radius of an animal, turning speed, the ability to accelerate […]

Meeting Abstract 49.2  Saturday, Jan. 5  Kinetics of quadrupedal locomotion on slippery and rough arboreal trackways LAMMERS, A.R.; Cleveland State Univ., Ohio a.Lammers13@csuohio.edu Most small quadrupedal mammals regularly encounter and move on fallen tree branches, twigs and logs. Arboreal substrates have a wide range of textures, but all studies of locomotion on arboreal substrates attempt to provide […]

Meeting Abstract 49.3  Saturday, Jan. 5  Independent Effects of Weight and Mass on Muscle Activity During Walking MCGOWAN, C.P.; University of Texas at Austin cpmcgowan@mail.utexas.edu Most studies agree that both gastrocnemius (GAS) and soleus (SOL) contribute to weight support during walking in humans. However, there is no current consensus as to the relative contribution of GAS and […]

Meeting Abstract 49.1  Saturday, Jan. 5  Climbing on the floor: Kinematics and energy cost of locomotion for horizontal and vertical crawling are not different WOODS JR., W. A.*; VANGRIETHUIJSEN, L.; TRIMMER, B. A. ; Tufts University; Tufts University; Tufts University william.woods@tufts.edu Regardless of body orientation, caterpillars accomplish forward locomotion by lifting , swinging forward, and replacing successive […]
