Carbohydrate catabolism and its role in water balance of the sand scorpion, Smeringurus mesaensis, during desiccation
Meeting Abstract 6.8 Jan. 4 Carbohydrate catabolism and its role in water balance of the sand scorpion, Smeringurus mesaensis, during desiccation GEFEN, E.; University of Nevada, Las Vegas gefene@unlv.nevada.edu Adult Smeringurus mesaensis (Vaejovidae) were desiccated at 30oC and 15-30%RH to 2.5, 5.0, 7.5 and 10% loss of initial mass. Oxygen consumption and CO2 emission rates at mass […]

Meeting Abstract 6.9 Jan. 4 Balancing the demands of physiological systems in the Dungeness crab, Cancer magister and the blue crab, Callinectes sapidus CURTIS, DL*; MCGAW, IJ; University of Nevada, Las Vegas; Bamfield Marine Sciences Centre; University of Nevada, Las Vegas; Bamfield Marine Scienes Centre curtisd4@unlv.nevada.edu Decapod crustaceans inhabiting estuaries are often subjected to salinity fluctuations that […]
Active ammonia uptake in the midgut of the tobacco hornworm Manduca sexta
Meeting Abstract 6.7 Jan. 4 Active ammonia uptake in the midgut of the tobacco hornworm Manduca sexta. WEIHRAUCH, Dirk; University of Osnabrueck, Osnabrueck, Germany weihrauchblues@gmx.net In Ussing chamber experiments the mid- and hindgut of Manduca sexta larvae were tested for their ammonia transport properties. In the presence of 0.1 mM ammonia on both sides of the isolated […]
Resonance in undulatory swimming of a robotic-flapping fish
Meeting Abstract 6.3 Thursday, Jan. 3 Resonance in undulatory swimming of a robotic-flapping fish LIM, J.L.**; LAUDER, G.V.; Harvard University, Cambridge, MA; Harvard University, Cambridge, MA lim@fas.harvard.edu The undulating body of a swimming fish has the potential to display resonance behaviour. Resonance in fish swimming can be characterized by an increase in the ratio of tail-beat amplitude […]
Pectoral fin biorobotics in fishes
Meeting Abstract 6.2 Thursday, Jan. 3 Pectoral fin biorobotics in fishes LAUDER, G. V.*; TANGORRA, J.; MITTAL, R.; MADDEN, P.; Harvard; MIT; George Washington; Harvard glauder@oeb.harvard.edu Many fishes are able to generate both propulsive (thrust) forces and maneuvering torques using their pectoral fins. Previous analyses of pectoral fin function in bluegill sunfish have demonstrated that the pectoral […]
Morphological and mechanical asymmetry in a biological gyroscope
Meeting Abstract 6.4 Thursday, Jan. 3 Morphological and mechanical asymmetry in a biological gyroscope. GEIGER, M.J.*; FOX, J.L.; MYHRVOLD, C.A.; DANIEL, T.L.; Univ.Washington, Seattle; Univ.Washington, Seattle; Pinceton Univ., Princeton; Univ.Washington, Seattle danielt@u.washington.edu Flies rely on mechanosensory input from reduced hindwings known as halteres to perform complex maneuvers. We are interested in how the mechanical properties of such […]
Locomotor Performance of Free-Swimming Robots Propelled by Biomimetic Tails
Meeting Abstract 6.1 Thursday, Jan. 3 Locomotor Performance of Free-Swimming Robots Propelled by Biomimetic Tails MCARTHUR, G*; GUTIERREZ, A; ROSENBLUM, H; SAHKTAH, H; STICKLES, E; DOORLY, N; LONG, J; Vassar College; Vassar College; Vassar College; Vassar College; Vassar College; Vassar College; Vassar College gimcarthur@vassar.edu Because they are simplified models of biological systems, free-swimming robots can be used […]
Computational fluid dynamics simulations of a vibrating sphere nearby a benthic fish in still and moving water
Meeting Abstract 6.5 Thursday, Jan. 3 Computational fluid dynamics simulations of a vibrating sphere nearby a benthic fish in still and moving water RAPO, M.A.**; JIANG, H.; GROSENBAUGH, M.A.; Woods Hole Oceanographic Institution, MA; Woods Hole Oceanographic Institution, MA; Woods Hole Oceanographic Institution, MA mrapo@whoi.edu Computational Fluid Dynamics (CFD) is used to compliment the many experiments which […]
Spatial aggregation promotes species coexistence among corals Evidence from experiments and modeling
Meeting Abstract 6.6 Sunday, Jan. 4 Spatial aggregation promotes species coexistence among corals: Evidence from experiments and modeling IDJADI, Joshua*; KARLSON, Ronald; New England Aquarium; University of Delaware jidjadi@neaq.org Scleractinian coral species with varying competitive abilities often occur in communities where shared resources are limited. Despite this, these communities can be very diverse, without dominance by the […]
