Meeting Abstract 54.5  Saturday, Jan. 5  Trade-offs between propulsion and filter feeding among three species of pelagic tunicates RAKOW, K.C.; MIT/WHOI Joint Program in Oceanography krakow@whoi.edu Salps are pelagic, barrel-shaped, jet-propelled swimmers that have higher filtering rates of small particles (1 µm- 1 mm) than almost any other planktonic grazer. The coupling of feeding and locomotion by […]

Meeting Abstract 54.8  Saturday, Jan. 5  The price of being special: consequences of specialisation of the hyolingual system in lizards. SCHAERLAEKEN, V*; HERREL, A; Univ. of Antwerp; Univ. of Antwerp vicky.schaerlaeken@ua.ac.be The form and function of the squamate hyolingual apparatus shows a tremendous diversity. Based on their tongue morphology, squamates can be divided into two groups: Iguania […]

Meeting Abstract 54.3  Saturday, Jan. 5  The power of display, and the aerodynamics and inertia in flapping pigeon wings USHERWOOD, JR; The Royal Veterinary College, London jusherwood@rvc.ac.uk Take-off, ascending and hovering flight is certainly energetically very demanding. Ascending flight is the major component of display flight in collared doves Streptopelia decaocto . Field recordings of these flights […]

Meeting Abstract 54.6  Saturday, Jan. 5  The Influence of Functional Architecture on the Rate and Direction of Phenotypic Evolution WALKER, J.A.; Univ. Southern Maine walker@maine.edu A general model of the functional constraints on the rate and direction of phenotypic evolution is developed using a decomposition of the Lande-Arnold model of multivariate phenotypic evolution. The important feature of […]

Meeting Abstract 54.4  Saturday, Jan. 5  Ontogenetic-Transitional Wing Hypothesis for the Evolution of Avian Flight DIAL, K.P.; Univ. Montana, Missoula kdial@mso.umt.edu The evolution of avian flight remains one of biology�s major controversies primarily because discussions and publications on the subject repeatedly offer arm-chair functional interpretations of fossil forms as evidence for either an arboreal (tree down) or […]

Meeting Abstract 54.1  Saturday, Jan. 5  Locomotor Constraints in Mice Selected for High Voluntary Wheel Running DLUGOSZ, E.M.*; CHAPPELL, M.A.; GARLAND, T, Jr.; University of California, Riverside; University of California, Riverside; University of California, Riverside edlug001@ucr.edu An expectation from studies of locomotor physiology is that highly mobile animals should evolve adaptations to facilitate running, such as changes […]

Meeting Abstract 54.11  Saturday, Jan. 5  Evolutionary Divergence in the Suction Feeding Mechanism of Fishes WILGA, C.D.; Univ. of Rhode Island cwilga@uri.edu Recent studies have increased our understanding of suction generation during feeding in actinopterygian fishes. However, whether sharks and rays, which lack the dermal bones of the head used extensively by actinopterygians in suction feeding, use […]

Meeting Abstract 54.2  Saturday, Jan. 5  Does body shape determine escape response performance in fishes? SWANSON, BO*; DIGIOVINE, CM; DORSEY, JP; ROSS, RN; Gonzaga University; Gonzaga University; Gonzaga University; Gonzaga University swansonb@gonzaga.edu To survive, nearly all fishes must swim quickly to avoid predators, often using a stereotyped C-start escape response behavior. Fishes also demonstrate extreme diversity in […]

Meeting Abstract 54.10  Saturday, Jan. 5  Do the pharyngeal jaws of moray eels constrain their oral jaw diversity and trophic ecology? MEHTA, Rita S; University of California, Davis rsmehta@ucdavis.edu The pharyngeal jaws of moray eels are highly specialized for transporting prey from the oral cavity into the oesophagus. The moray pharyngeal jaws represent a functional innovation which […]

Meeting Abstract 54.9  Saturday, Jan. 5  Complexity in the suction feeding mechanism mitigates a diet tradeoff in centrarchid fishes. COLLAR, David; University of California, Davis dccollar@ucdavis.edu Tradeoffs are pervasive in organismal design and often shape ecological diversification. Structures that perform multiple functions are subject to several, often-opposing selection pressures, which may limit their evolution. The size of […]
