Meeting Abstract 136-1 Sunday, Jan. 7 13:30 – 13:45 Iterative signaling and biological system performance O’CONNOR, MP*; O’DONNELL, S; Drexel University; Drexel University oconnomp@drexel.edu Responses of hierarchically organized biological systems (e.g., insect colonies, nervous systems) to stimuli often depend on the recruitment of individual subunits (e.g., insects, neurons) to specified tasks. We developed a Markov chain based […]

How Social and Environmental Context Shapes Fighting Behavior in Tilapia
Meeting Abstract 136-3 Sunday, Jan. 7 14:00 – 14:15 How Social and Environmental Context Shapes Fighting Behavior in Tilapia STIENECKER, SL*; MOORE, PA; Bowling Green State University; Bowling Green State University sarals@bgsu.edu Animals engage in aggressive contests frequently as a result of competition over resources. In order to more accurately weigh costs and benefits of withdrawing from […]

Conserved genes regulate phenotypic plasticity in an incipiently social bee
Meeting Abstract 136-6 Sunday, Jan. 7 14:45 – 15:00 Conserved genes regulate phenotypic plasticity in an incipiently social bee REHAN, SM; University of New Hampshire sandra.rehan@unh.edu http://www.rehanlab.com The genetic underpinnings of social behavior are of great interest to understanding the evolution of social complexity. Genomic data for solitary and eusocial species are now available and have revealed […]
Viscous shearing in the sarcomere
Meeting Abstract 135-2 Sunday, Jan. 7 13:45 – 14:00 Viscous shearing in the sarcomere MALINGEN, SA*; CASS, JA; DANIEL, TL; Univ. of Washington; Univ. of Washington; Univ. of Washington danielt@uw.edu http://faculty.washington.edu/danielt/ Cells interact dynamically with their environment, often altering their structure in response to stimuli. Architectural changes within cells occur in a (generally) small fluid filled environment, […]

Predicting in vivo muscle force in running guinea fowl using a muscle model based on the winding filament hypothesis
Meeting Abstract 135-8 Sunday, Jan. 7 15:15 – 15:30 Predicting in vivo muscle force in running guinea fowl using a muscle model based on the winding filament hypothesis WHITNEY, CW*; DALEY , MA; NISHIKAWA, K; Northern Arizona University ; Royal Veterinary College; Northern Arizona University cw729@nau.edu Although a large amount of effort has been put towards modeling […]
Load-dependent muscle work tunes perturbation response with changing running frequency
Meeting Abstract 135-6 Sunday, Jan. 7 14:45 – 15:00 Load-dependent muscle work tunes perturbation response with changing running frequency. LIBBY, T*; CHUKWUEKE, C; SPONBERG, S; University of Washington; Georgia Institute of Technology; Georgia Institute of Technology tlibby@berkeley.edu Muscle’s intrinsic properties can stabilize movement through the length- and velocity-dependence encompassed in Hill-like models, but these models fail to […]
Flow and diffusion together mediate substrate delivery into the crowded lattice of contractile filaments
Meeting Abstract 135-1 Sunday, Jan. 7 13:30 – 13:45 Flow and diffusion together mediate substrate delivery into the crowded lattice of contractile filaments CASS, J.A.*; DANIEL, T.L.; Univ. of Washington; Univ. of Washington danielt@uw.edu http://faculty.washington.edu/danielt/ Muscle contraction is mediated by myosin motors that derive their energy from ATP hydrolysis. Recent research suggests that diffusion may be limiting […]
