ROWE, T. B.; MACRINI, T. E. ; EITING, T. P.; KETCHAM, R. A.; Jackson School of Geosciences, The University of Texas at Austin, Austin, Texas 78712: The Olfactory and Respiratory Skeleton in the Nose of the Opossum Monodelphis domestica The internal nasal skeleton in Monodelphis (www.DigiMorph.org) supports olfactory and respiratory epithelia, the vomeronasal organ, and […]

VEILLETTE, P.A.; GARCIA, M.M.; SPECKER, J.L.; University of Rhode Island: Immunolocalization of corticosteroid receptor with proliferating cell nuclear antigen and proton pump during stomach formation in metamorphosing summer flounder. Formation of gastric glands is a hallmark of stomach development during larval metamorphosis of the gastric marine teleosts. Organogenesis occurs in an orderly progression of epithelial […]

NORTHCUTT, R.G.; University of California, San Diego: External taste buds in channel catfish are not neurally induced The predominant theory of taste bud induction has been the neural induction theory, according to which the peripheral processes of the facial, glossopharyngeal and vagal nerves invade the oropharyngeal epithelium and induce taste bud primordia. There is growing […]

SERRANO, X.; GARCIA, M.M.; VEILLETTE, P.A.; SPECKER, J.L.; University of Rhode Island: Cortisol regulation in larval summer flounder (Paralichthys dentatus) In teleosts, cortisol is primarily produced in the diffuse interrenal tissue and circulating levels are regulated through feedback inhibition on the hypothalamus and pituitary. However, it is not clear when auto-regulation of the hypothalamic-pituitary-interrenal (HPI) […]

VANCE, Jason T.; ALTSHULER, Douglas L.; DICKINSON, Michael H.; ROBERTS, Stephen P.; Univ. of Nevada, Las Vegas; California Institute of Technology; California Institute of Technology; Univ. of Nevada, Las Vegas: High-speed kinematic analysis of honey bees (Apis mellifera) hovering in variable density atmospheres: Insights into aerodynamic reserve capacity and performance limitations For flying insects, behaviors […]

VOLTZOW, J.*; MARTIN, C.-L.; Univ. of Scranton, Pennsylvania, USA; Univ. of New England, National Marine Science Centre, New South Wales, Australia: Flow in Fissurellids: A Story Full of Holes Most fissurellid gastropods, or keyhole limpets, are characterized by a cap-shaped shell with an apical opening. Their mantle cavities contain paired organs, including a large pair […]

FISH, Frank/E; NICASTRO, Anthony/J; West Chester Univ., Pennsylvania; West Chester Univ. , Pennsylvania: Dynamics of the aerial maneuvers of spinner dolphins The spinner dolphin (Stenella longirostris(/i>) performs spectacular leaps from the water while rotating around its longitudinal axis up to seven times. Although twisting of the body while airborne has been proposed as the mechanism […]

VON DASSOW, M; Univ. of California, Berkeley: Does fluid flow control pattern formation in a colonial suspension feeder? Biological fluid transport systems have many functions in different organisms, including gas exchange and feeding. To what extent does the flow through the system determine subsequent pattern formation of the system during an organism�s growth? Colonies of […]

LONG, JR., J.H.; HOBSON, B; PELL, C; SCHUMACHER, J; KEMP, M; Vassar College; Nekton Research LLC; Nekton Research LLC; Vassar College; Nekton Research LLC: Biorobotics: A Four-Finned Underwater Vehicle for Locomotor Research In order to test functional predictions about fin-based swimming, we have designed and built an underwater, remotely-operated vehicle with four independently controlled fins. […]

GRUBICH, JR; WESTNEAT, MW; The Field Museum of Natural History; The Field Museum of Natural History: Bichirs, Bowfins, and Gars, Oh My! Functional Morphology of Pectoral Fin Locomotion in Basal Actinopterygian Fishes Pectoral fin locomotion has been investigated across a phylogenetically broad range of fishes including elasmobranchs, acipenseriformes, and teleosts; yet, there are several actinopterygian […]
