DAY, S W*; HIGHAM, T E; WAINWRIGHT, P C; Rochester Institute of Technology; Univ. of California, Davis; Univ. of California, Davis: THE RELATION OF SUCTION PRESSURE AND FLUID SPEED DURING FEEDING IN LARGEMOUTH BASS The suction feeding fish simultaneously generates negative pressure within the mouth and a flow field external to its head that draws […]

FRANCIS, A.W.; Villanova University, PA: Phylogeny and Feeding Biomechanics of Pleuronectiform Fishes Mechanical advantage of lower jaw depression and elevation was determined for five families and 10 genera of pleuronectiform fishes. Of the 11 species examined, five were sinistral and six dextral. Mechanical advantage for both lower jaw depression and elevation was lowest for species […]

MARKEY, M. J.*; MAIN, R. P.; MARSHALL, C. R.; Harvard University; Harvard University; Harvard University: In vivo cranial suture function and suture morphology in the extant fish Polypterus This study describes the mechanical role cranial sutures play in fish during feeding, and presents a quantification of fish suture morphology using microCT scanning. To measure suture […]

RICE, Aaron N.; University of Chicago and Field Museum of Natural History: Evolution of Coordination in Fish Feeding: The Intersection of Functional Morphology and Ecology Prey capture in fishes is a complex behavioral process. From initial sensory detection of a food item, to the final motor output of jaws and fins, these components have to […]

PADIAN, K.*; DIAL, K.P.; University of California, Berkeley; University of Montana, Missoula: Was there a “four-winged” transitional stage between dinosaurs and birds? The recent discovery of long leg feathers on the first known bird, the Jurassic Archaeopteryx, a related small non-avian Cretaceous theropod, Microraptor, and a basal Cretaceous enantiornithine bird has fueled speculation that the […]

BUNDLE, M/W*; DIAL, K/P; Rice University, Houston ; Univeristy Of Montana, Missoula: Power requirements of bird flight with additional mass In the wild, birds routinely fly appreciable distances supporting the weight of prey items, nest material, water, and short-term fat stores. Under experimental conditions, subject animals are often encumbered with recording equipment (e.g. satellite transmitters, […]

COMBES, S.A.*; DUDLEY, R.; Univ. of California, Berkeley: Limits to maximum flight velocity: Pitch control and roll instability in orchid bees during fast, forward flight Maximum velocity is a critical component of flight performance, but observing or eliciting maximum flight speeds is difficult in most flying animals. Flight velocity is thought to be limited by […]

BERG, A.M.*; BIEWENER, A.A.; Harvard University; Harvard University: Differences among Ascending, Level, and Descending Flapping Flight Rock pigeons (Columba livia) flew along paths of varying angles of ascent and descent. Flights at angles of 60, 30, 0, -30, and -60 degrees were recorded with high-speed video. Kinematic marks were then digitized. During ascending flight, pigeons […]

BREWER, Michael/L*; CHEVIRON, Zac/A; BRUMFIELD, Robb/T; ROBERTS, Stephen/P ; University of Nevada, Las Vegas; Louisiana State University; Louisiana State University; University of Nevada, Las Vegas: Altitudinal variation of wing shape in the Andean passerine Zonotrichia capensis A challenge common to both engineered and biological volant forms is flight at high altitudes, where the density of […]
