BOND, C; Greensboro College, North Carolina: Comparative Time-Lapse Studies of Two Different Sponge Designs Most time-lapse microscopy studies on sponges have been done on those with leuconoid canal architecture (seen in a majority of sponges). This present study has initiated time-lapse examinations of live asconoid sponges. It was hoped that recording asconoid sponges, with their […]

Meeting Abstract 14.4  Jan. 4  Functional morphology of the python heart STARCK, J.M.; Univ. Munich, Germany starck@uni-muenchen.de Snakes, like all other ectotherm sauropsids, have a complicated heart anatomy, with five functional chambers: left and right atrium, the Cavum arteriosum, the C. venosum and the C. pulmonale. The C. venosum and C. pulmonale are connected by a wide […]

M.; Institute of Arctic Biology, University of Alaska Fairbanks oivind.toien@uaf.edu Black bears depress metabolic rate to about 25% of normal resting levels during hibernation with a decrease of core temperature […]

Meeting Abstract 14.6  Jan. 4  A Novel Assessment of Hemodynamics in the Intact Trout Heart COTTER, P/A; EVERSON, J/J; RODNICK, K/J*; Univ. of Alaska Anchorage; Diagnostic Imaging of Idaho; Idaho State University afpac1@uaa.alaska.edu For the first time, we used simultaneous electrocardiography and echocardiography to characterize hemodynamics of the salmonid heart in vivo. We determined timing patterns of […]

Meeting Abstract 14.2  Thursday, Jan. 3  What limits running speed in race horses SPENCE, A.J.*; WILSON, A.; Royal Veterinay College; Royal Veterinay College aspence@rvc.ac.uk During thoroughbred horse racing equine athletes strive for maximum performance. As a result, the level of effort of horses during racing can be considered to be roughly constant, and of the highest achievable […]
