Meeting Abstract 19.5  Wednesday, Jan. 4  Does the SLIP Model Apply During Inverted Running in Cockroaches? PARIKH, S.C.*; MARA, K.R.; HSIEH, S.T.; Temple University; Temple University; Temple Unviersity sachincp16@temple.edu Center of mass (COM) dynamics during upright locomotion is described by the spring loaded inverted pendulum (SLIP) model. According to this model, gravity pulls the COM towards the […]

Meeting Abstract 18.4  Wednesday, Jan. 4  The role of the abdominal pump in rhythmic tracheal compression in the ground beetle, Pterostichus tristis DALTON, E.*; SOCHA, J.J.; Virginia Tech; Virginia Tech elan@vt.edu Abdominal pumping is a widespread behavior in insects, with multiple physiological roles that include respiration and circulation.

Meeting Abstract 18.2  Wednesday, Jan. 4  Dynamics of the sucking pump in fluid feeding butterflies ROBERTS, C.*; SOCHA, J.J.; Virginia Tech; Virginia Tech carolyn2@vt.edu Butterflies feed by means of a sucking pump in the head, which creates a pressure gradient to drive food through the proboscis. Although the functional morphology of internal food transport of Lepidoptera has […]

Meeting Abstract 17.5  Wednesday, Jan. 4  Unsteadiness of Bivalve Clam Jet Flow According to Environmental Conditions and Predator Presence WEBSTER, D.R.*; DELAVAN, S.K.; Georgia Institute of Technology; University of Canterbury dwebster@ce.gatech.edu This study attempts to determine the patterns and/or randomness of the excurrent velocity of actively feeding clams, Mercenaria mercenaria. We hypothesize that clams alter their feeding […]
