Meeting Abstract 70.4  Sunday, Jan. 6  Larval Development of a Neritimorph Gastropod Identifies Derived Traits Among Feeding Gastropod Larvae PAGE, L.R.*; LESOWAY, M.P.; University of Victoria lpage@uvic.ca Mapping of gastropod life histories onto recent phylogenetic hypotheses predicts that larval feeding (planktotrophy) is a derived trait among gastropods. Feeding larvae are present in three clades: caenogastropods, heterobranchs, and […]

Meeting Abstract 70.2  Sunday, Jan. 6  Enigmatic transitory epidermis in planktonic larval development of a hoplonemertean Paranemertes peregrina and its significance in evolution of development in nemerteans (Phylum Nemertea; Lophotrochozoa) MASLAKOVA, S. A.*; VON D�HREN, J.; U of Washington; Freie Universit�t Berlin maslak@u.washington.edu Nemerteans are non-segmented marine worms related to the trochophore-bearing phyla such as Mollusca and […]

Meeting Abstract 70.5  Sunday, Jan. 6  Centipedes and crayfish � Two extreme modes of sequential segmentation in arthropods CHIPMAN, A.D.; The Hebrew University of Jerusalem ariel.chipman@huji.ac.il The majority of arthropods generate segments sequentially during embryogenesis, a process usually referred to as �short germ development.� This is in contrast with the well studied process in Drosophila melanogaster, where […]

Meeting Abstract 70.6  Sunday, Jan. 6  Borrowing from the past: Remodeling adult tissue by larval cell recruitment during Ciona heart development DAVIDSON, Brad*; NUNAN, Linda; University of Arizona; University of Arizona bjd18@email.arizona.edu During chordate evolution, there have been dramatic life-history shifts between direct and indirect modes of development. These shifts may facilitate the emergence of new traits. […]

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.
