Meeting Abstract 71.2  Wednesday, Jan. 6  Do vespertilionid bats have a third wing? ADAMS, R.A.**; SNODE, E.; Univ. of Northern Colorado, Greeley rick.adams@unco.edu Although the uropatagium of vespertilionid bats is well known for its use as an insect catchment during foraging, the inter-femoral membrane has been largely ignored as an active contributor to flight mechanics. Indeed, the […]

Meeting Abstract 71.5  Wednesday, Jan. 6  Bat flight and hierarchies of variability HUBEL, T.Y.*; HRISTOV, N.I.; RISKIN, D.K.; SWARTZ, S.M.; BREUER, K.S.; Brown University tatjana_hubel@brown.edu Kinematics as well as morphology differ greatly among the approximately 1200 living species of bats, and it is crucial to understand the effects that the body, wing shape and pattern of wing […]

Meeting Abstract 71.3  Wednesday, Jan. 6  Wing folding in bats: Aspects of morphology and phylogenetic interpretation ARMOUR, Maria T.*; SIMMONS, Nancy B.; SCHUTT, WIlliam A. Jr.; Emerson College, Boston, MA; American Museum of Natural History, New York, NY; C.W. Post College of Long Island University, Brookville, NY m.t.armour@gmail.com The bat forelimb is functionally unique among mammals because […]

Meeting Abstract 71.6  Wednesday, Jan. 6  The effect of wingbeat frequency on aerodynamic force and wake structure using a bat-like mechanical flapper BAHLMAN, Joseph Wm*; SCHUNK, Cosima; SWARTZ, Sharon M.; BREUER, Kenneth S.; Brown University; Hochschule Bremen, University of Applied Sciences; Brown University; Brown University joseph_bahlman@brown.edu The aerodynamic forces produced by a bat’s wings depends on its […]

Meeting Abstract 71.1  Wednesday, Jan. 6  Primary Downstroke Muscle Activity and Shoulder Movements in Free-tailed Bats. HERMANSON, J.W.*; ALTENBACH, J.S.; Cornell Univ., Ithaca; Univ. of New Mexico, Albuquerque jwh6@cornell.edu We explored several hypotheses about primary downstroke muscle function and skeletal motion in free-tailed bats (Tadarida brasiliensis). Bats were implanted with 0.2 mm diameter stainless steel pins in […]

Meeting Abstract 71.4  Wednesday, Jan. 6  Kinematics of a fast bat: Changes in wing kinematics with flight speed in the migratory bat (Tadarida brasiliensis) HRISTOV, N.I.*; RISKIN, D.K.; HUBEL, T.Y.; ALLEN, L.C.; BREUER, K.S.; SWARTZ, S.M.; Brown University, Providence, RI nickolay_hristov@brown.edu Bats are unique among mammals in their ability to fly. Although flight in bats originated from […]

Meeting Abstract 70.2  Wednesday, Jan. 6  Scaling of escape flight performance, power output, and muscle function in perching birds JACKSON, B.E.; The University of Montana, Missoula brandon.jackson@mso.umt.edu Patterns of scaling in animal locomotion offer insight to physical constraints imposed on evolution. Flight, being metabolically costly yet evolutionarily successful, is a particularly useful locomotor behavior through which to […]

Meeting Abstract 70.6  Wednesday, Jan. 6  Precocial hindlimbs and altricial forelimbs of developing Mallard ducks: A study of locomotor performance and morphometrics DIAL, TR*; CARRIER, DR; University of Utah; University of Utah trdial@gmail.com The young of some precocial species exhibit near-adult levels of locomotor performance. Waterfowl (Anseriformes) have an unusual developmental trajectory wherein their precocial hindlimbs exhibit […]
