Meeting Abstract P2.72  Jan. 5  How do you scrape? Diversity and development of teeth and horny lip projections among the Loricariidae GEERINCKX, T.*; DE POORTER, J.; MAES, D.; NIJS, K.; ADRIAENS, D.; Ghent University tom.geerinckx@ugent.be The neotropical suckermouth armored catfishes use their sucker-like mouth to adhere to submerged substrates. They have drastically modified jaws that point their […]

Meeting Abstract P2.46  Jan. 5  Heterochrony in avian brain development STRIEDTER, G.F.; Univ. of California, Irvine gstriedt@uci.edu The brains of adult birds differ widely in size and proportions. Parrots, in particular, are known for having large brains, relative to body size, and disproportionately large forebrains, whereas domestic chickens have surprisingly small forebrains and optic lobes. The developmental […]

Meeting Abstract P2.67  Jan. 5  Gross morphology of the respiratory muscles in bottlenose dolphins (Tursiops truncatus) COTTEN, P.B.**; PISCITELLI, M.A.*; MCLELLAN, W.A.; ROMMEL, S.A.; PABST, D.A.; UNC Wilmington; UNC Wilmington; UNC Wilmington; UNC Wilmington; UNC Wilmington pbc7783@uncw.edu Bottlenose dolphins (Tursiops truncatus) possess locomotor stamina; however, the dolphin�s locomotor-respiratory systems are decoupled while swimming on a breath-hold. During […]

Meeting Abstract P2.71  Jan. 5  Gill Slit Kinematics During Ventilation and Feeding in Bamboo Sharks KARCH, A.P.*; DOLCE, J.L.; WILGA, C.D.; Univ. of Rhode Island akarch@mail.uri.edu Feeding and ventilation are behaviors that are critical to individual survival. Aquatic vertebrates use the same cranial structures to ventilate and feed resulting in diverse functional demands on shared structures. Thus, […]

Meeting Abstract P2.64  Jan. 5  Genic capture, environmental variation and good genes in gray tree frogs WELCH, A.M.**; SMITH, M.J.; GERHARDT, H.C.; College of Charleston, SC; Arthur Rylah Institute, Victoria, AUS; Univ. of Missouri, Columbia welcha@cofc.edu Several hypotheses have been proposed to explain the maintenance of genetic variation in sexually-selected traits. The genic-capture model predicts that condition-dependent […]

M.; Washington University, St. Louis; Washington University, St. Louis; Washington University, St. Louis; Washington University, St. Louis pavlicev@pcg.wustl.edu The phenotype can be described as hierarchical complexes of integrated units. One aspect of the genetic architecture of such units […]

Meeting Abstract P2.139  Jan. 5  Funky Olfaction In Fluctuating Flows: Does A Crayfish Nose Know How To Make Sense Of Scents? MEAD, K. S.; Denison Univ., Granville OH meadk@denison.edu Through a variety of physical mechanisms and at several scales, the local flow environment affects the shape of waterborne chemical signals. For instance, waves, current, turbulence, and substrate […]

Meeting Abstract P2.66  Jan. 5  Functional Morphology of Inking Behavior in Pygmy & Dwarf Sperm Whales MARSHALL, CD; MOSS, AL*; Texas A&M University marshalc@tamug.edu Pygmy & dwarf sperm whales (Kogia breviceps and K. sima) demonstrate an unusual inking behavior similar to cephalopods. Such behavior is unknown among other cetaceans. The source of ink is hypothesized to be […]
