Meeting Abstract 14.1 Sunday, Jan. 4 10:15 The three-dimensional structure of fish scales WAINWRIGHT, DK*; LAUDER, GV; Harvard University; Harvard University dylan.wainwright@gmail.com Fish scales are morphologically diverse, both among species, within species, and on an individual. Scales are often categorized into three main types: cycloid scales have smooth edges; spinoid scales have spines protruding from the body […]

The Effects of Anthropogenic and Natural Barriers on Fish Morphology a Geometric Morphometric Analysis
Meeting Abstract 14.7 Sunday, Jan. 4 11:45 The Effects of Anthropogenic and Natural Barriers on Fish Morphology: a Geometric Morphometric Analysis KNOLL, K.M.*; LEONARD, J.B.K.; Northern Michigan University; Northern Michigan University kknoll@nmu.edu Dams are one of the most widespread and disruptive anthropogenic modifications of ecosystems worldwide. While it has been shown that large dams with upstream reservoirs […]
Shape Trajectory Analysis Using Procrustes Analysis and VARMA Models
Meeting Abstract 14.5 Sunday, Jan. 4 11:15 Shape Trajectory Analysis Using Procrustes Analysis and VARMA Models SODA, KJ*; SLICE, DE; Florida State University, Tallahassee; Florida State University, Tallahassee k.jamessoda@gmail.com Geometric morphometric (GM) methods have revolutionized how studies into comparative morphology are undertaken. Most GM methods, however, can only be used on specimens whose shapes are fixed, barring […]
Island dwarfing and cranial morphology in Southeast Asian mammals
Meeting Abstract 14.4 Sunday, Jan. 4 11:00 Island dwarfing and cranial morphology in Southeast Asian mammals YAO, L.*; MARTIN, R.D.; University of Chicago, Chicago; The Field Museum, Chicago luyaozers@uchicago.edu The island rule states that large-bodied mammals generally undergo reduction in body size on islands (especially small ones) mostly due to resource limitation. But evolution of cranial morphology […]
3D surface-based morphometrics used to determine the intraspecific differences within the tail of syngnathid fishes
Meeting Abstract 14.2 Sunday, Jan. 4 10:30 3D surface-based morphometrics used to determine the intraspecific differences within the tail of syngnathid fishes NEUTENS, C; DE DOBBELAER, B; CLAES, P; ADRIAENS, D*; Ghent University; Catholic University Leuven; Catholic University Leuven; Ghent University dominique.adriaens@ugent.be http://www.fun-morph.ugent.be Seahorses and pipehorses both possess a prehensile tail, a unique characteristic among teleost fishes, […]
Scaling of muscle contractile properties depends on the inertial mass within the muscle
Meeting Abstract 14-7 Monday, Jan. 4 11:45 Scaling of muscle contractile properties depends on the inertial mass within the muscle WAKELING, JM*; ROSS, SA; Simon Fraser University; Simon Fraser University wakeling@sfu.ca During contraction, muscles must do internal work to deform their tissue and in particular to overcome the inertia of the individual elements within the muscle. However, […]
Predicting greyhound sit-to-stand muscle dynamics using computer simulation
Meeting Abstract 14-1 Monday, Jan. 4 10:15 Predicting greyhound sit-to-stand muscle dynamics using computer simulation HUTCHINSON, J.R.*; ELLIS, R.G.; RANKIN, J.W.; Royal Veterinary College, UK; Royal Veterinary College, UK; Royal Veterinary College, UK jhutchinson@rvc.ac.uk http://www.rvc.ac.uk/sml Despite being a critical daily activity for many mammals, how species transition from supine to standing postures is not clear. Only human […]
Muscle physiology and architecture as an axis of variation in functional diversity
Meeting Abstract 14-6 Monday, Jan. 4 11:30 Muscle physiology and architecture as an axis of variation in functional diversity GIDMARK, NJ*; GIAMMONA, F; KACZMAREK, E; ROBERTS, A; University of Chicago; Cornell University; University of Miami; Perdue University gidmark@uchicago.edu Examining functional diversity and its evolutionary patterns requires quantification of a particular trait as a metric for disparity between […]
Muscle mechanical performance in wild and domestic turkeys
Meeting Abstract 14-5 Monday, Jan. 4 11:15 Muscle mechanical performance in wild and domestic turkeys STOVER, KK*; BRAINERD, EL; ROBERTS, TJ; Brown University; Brown University; Brown University kristin_stover@brown.edu The poultry industry has bred domestic turkeys to have much larger muscles than wild turkeys, but it is unclear if this intense artificial selection for greater muscle mass affects […]
Functional imaging from the muscles of the fruit fly wing-hinge during tethered flight
Meeting Abstract 14-4 Monday, Jan. 4 11:00 Functional imaging from the muscles of the fruit fly wing-hinge during tethered flight. LINDSAY, TH*; DICKINSON, MH; Caltech thlindsay1@gmail.com Animal movement emerges from a system of inner and outer-feedback loops by which sensory information directs and stabilizes motor output. Compared to our knowledge of coding within sensory systems, our understanding […]
