Meeting Abstract 71.4  Tuesday, Jan. 6  Muscle mass limtis suction feeding performance among three centrarchid species. CARROLL, Andrew M.*; HUSKEY, Steve; WAINWRIGHT, Peter C.; University of Evansville, Evansville, IN ac204@evansville.edu The influence of musculoskeletal design on suction feeding performance (i.e. volumetric expansion and sub-ambient pressure generation) is not quantitatively or generally established. It has been hypothesized that […]

Meeting Abstract 71.3  Tuesday, Jan. 6  Integrated diversification of suction feeding performance in centrarchid and cichlid fishes WAINWRIGHT, P.C.**; HOLZMAN, R.A.; MEHTA, R.S.; HULSEY, C.D.; Univ. of California, Davis; Univ. of California, Davis; Univ. of California, Davis; Univ. of Tennessee, Knoxville pcwainwright@ucdavis.edu Suction feeding ability has been shown to have a complex underlying basis with numerous avenues […]

Meeting Abstract 71.1  Tuesday, Jan. 6  Heads, Jaws, and Feeding: In Search of the Basal Chondrichthyan Condition. GROGAN, E.D.*; LUND, R; Saint Joseph’s University; Carnegie Museum egrogan@sju.edu Chondrichthyans, represented today by sharks, skates, rays, and chimaeras, are gnathostomes with an evolutionary history spanning 400-500 million years. They are often invoked to exemplify the primitive jawed vertebrate condition […]

Meeting Abstract 71.5  Tuesday, Jan. 6  Correlated evolution of feeding morphology in piscivorous versus non-piscivorous centrarchid fishes COLLAR, D.*; REVELL, L.; Harvard University; Harvard University dcollar@oeb.harvard.edu We used a new phylogenetic comparative method to test whether an inferred shift in selective regime associated with the evolution of piscivory in centrachid fishes has led to changes in the […]

Meeting Abstract 70.2  Tuesday, Jan. 6  Scaling of flight characteristics in bats SWARTZ, SM*; RISKIN, DK; IRIARTE, J; MIDDLETON, KM; BREUER, KS; Brown University; Brown University; University of Chicago; California State University, San Bernardino; Brown University sharon_swartz@brown.edu The more than 1200 living bat species range in body size from 2 g to >1,500 g but share a […]

Meeting Abstract 70.1  Tuesday, Jan. 6  Patterns of Variation in Chiropteran Wing Folding: With Special Attention to Differences in Joint Morphology ARMOUR, Maria T.; C.W. Post Campus of Long Island University m.t.armour@gmail.com Bats (Chiroptera) are a diverse group, with more than 1,200 species worldwide, and flight is the synapomorphy that has permitted them to diversify in habitat, […]

Meeting Abstract 70.6  Tuesday, Jan. 6  Oh what a feeling: the kinematics and kinetics of landing on a ceiling. RISKIN, D K*; BAHLMAN, J Wm; HUBEL, T Y; RATCLIFFE, J M; KUNZ, T H; SWARTZ, S M; Brown University; Brown University; Brown University; University of Southern Denmark; Boston University; Brown University dkr8@brown.edu Flying animals exhibit obvious adaptations […]

Meeting Abstract 70.3  Tuesday, Jan. 6  No net thrust on the upstroke: the effect of wing inertia on body accelerations of fruit bats during flight IRIARTE-DIAZ, J*; RISKIN, D. K.; SWARTZ, S. M.; Brown University; Brown University; Brown University jiriarte@uchicago.edu During slow flight, some bats species produce a tip-reversal upstroke, where the distal portion of the wing […]

Meeting Abstract 70.5  Tuesday, Jan. 6  Individual variability in the aerodynamics and kinematics of bat flight HUBEL, Tatjana*; BREUER, Kenneth; SWARTZ, Sharon; Brown University tatjana_hubel@brown.edu Many studies on the aerodynamics of flight in birds and bats use relatively few individuals. However, previous work in our lab has shown that the kinematics of flight can vary significantly from […]

Meeting Abstract 70.4  Tuesday, Jan. 6  Computational modeling of the aeromechanics of a bat (Cynopterus brachyotis) WILLIS, D.J.*; RISKIN, D.K.; SWARTZ, S.M.; PERAIRE, J.; BREUER, K.S.; Univ. Massachusetts, Lowell; Brown Univ.; Brown Univ.; Massachusetts Institute of Technology; Brown Univ. david_willis@uml.edu Bat flight represents a complex interaction between unsteady fluid flow and the material that composes the wing.
