UYENO, Theodore A.; KIER, William M.; Univ. of North Carolina, Chapel Hill; Univ. of North Carolina, Chapel Hill: The function of cephalopod buccal mass musculature The buccal mass of cephalopods includes a pair of jaws termed �beaks� that are used to masticate prey. The beaks perform complex movements, yet do not articulate with one another. […]

DAVIS, G.K.*; WITTKOPP, P.J.; STERN, D.L.; Princeton University; Cornell University; Princeton University: The evolution and regulation of Ubx in the pupal legs of Drosophila The fruit fly Drosophila melanogaster possesses a small region of naked cuticle on the T2 femur from which trichomes (hairs) are excluded. Other members of the subgenus sophophora, such as Drosophila […]

BAGLEY, J.C.*; SECOR, S.M.; University of Alabama, Tuscaloosa; University of Alabama, Tuscaloosa: The allometry of metabolic and intestinal performance for the marine toad and diamondback water snake To investigate the potential interactions between the allometry of metabolic rates and intestinal performance, we assess the effects of body mass on standard metabolic rates, intestinal mass, intestinal […]

LYNN, S. E.; COOMBS-HAHN, T. P. ; BREUNER, C. W. ; The College of Wooster; University of California, Davis; University of Texas, Austin: Testosterone, corticosterone, and binding globulins: plasma interactions and aggressive behavior in mountain white-crowned sparrows (Zonotrichia leucophrys oriantha) Male-male aggression over territory boundaries is common during the breeding season for many birds. In […]

ROSTAL, DC; WIBBELS, T; Georgia Southern University; Univ. of Alabama at Birmingham: Temperature-dependent Sex Determination and Embryonic Development of the Gopher Tortoise (Gopherus polyphemus): A Latitudinal Investigation. The gopher tortoise (Gopherus polyphemus) has been demonstrated to possess TSD in laboratory studies. No studies have however attempted to see how these laboratory results can be applied […]

ALEXANDER, J.K.*; TYTELL, E.D.; Harvard University; Harvard University: Synchronization of respiration and locomotion in the bluegill sunfish Lepomis macrochirus To determine if fish synchronize their locomotion and respiration, we filmed bluegill sunfish (Lepomis macrochirus) using high-speed video and calculated the time differences between locomotory and respiratory events. It is well known that many tetrapods, from […]

GERRY, S.P.*; DEAN, M.N.; University of Rhode Island; University of California, Irvine: Symphyseal force transmission in the jaws of Squalus acanthias Complete fusion of the symphysis stiffens and strengthens the jaws to allow large bite forces to be generated. An unfused symphysis is functionally versatile, however, is likely poor at transmitting forces across the jaws. […]
