How strong are flow-mediated interactions among neighbouring barnacles
Meeting Abstract 55.4 Saturday, Jan. 5 How strong are flow-mediated interactions among neighbouring barnacles? NEUFELD, Christopher J*; PALMER, A Richard; Univ. of Alberta and Bamfield Marine Sciences Centre chris.neufeld@ualberta.ca On rocky shores, water movement varies dramatically in space and time and influences the ecology and form of many organisms. For example, both size and form of barnacle […]

Meeting Abstract 55.1 Saturday, Jan. 5 Acanthamoeba (Gymnamoebae:Acanthamoebidae) Distribution in the Chester River of the Eastern Shore of Maryland BELL, C.L.; MUNSON, D.A.*; Washington College; Washington College dmunson2@washcoll.edu The large diversity of amoebae species in soils and sewage sludge reported by Singh and Hanumaih (Monograph No. 1 of the Association of Microbiologists of India, Indian Journal of […]
Trade-offs between propulsion and filter feeding among three species of pelagic tunicates
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 […]
The price of being special consequences of specialisation of the hyolingual system in lizards
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 […]
The power of display, and the aerodynamics and inertia in flapping pigeon wings
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 […]
The Influence of Functional Architecture on the Rate and Direction of Phenotypic Evolution
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 […]
Ontogenetic-Transitional Wing Hypothesis for the Evolution of Avian Flight
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 […]
