Y-axis orientation in South American freshwater snails (Chilina spp)
Meeting Abstract 43.10 Thursday, Jan. 5 Y-axis orientation in South American freshwater snails (Chilina spp.) LANDLER, Lukas*; VON OHEIMB, Parm V; Virginia Tech, USA, Blacksburg and Natural History Museum of Vienna, Austria; Department of Animal Ecology and Systematics, Germany, Gießen lukasl@vt.edu Y-axis orientation, defined here as movement perpendicular to the shore- or coastline, enables aquatic animals to […]
Vision-based altitude control in freely flying Drosophila
Meeting Abstract 43.4 Thursday, Jan. 5 Vision-based altitude control in freely flying Drosophila ZABALA, F.A.*; DICKINSON, M.H.; Univ. of Washington zabala@caltech.edu Insects are thought to achieve robust flight stability through the implementation of rapid sensory-motor reflexes. Specialized interneurons within their visual system detect unintended rotations and translations during flight and convey that information to motor circuits that […]

Peristaltic burrowing in beach sands by the polychaete Thoracophelia mucronata
Meeting Abstract 43.9 Thursday, Jan. 5 Peristaltic burrowing in beach sands by the polychaete Thoracophelia mucronata DORGAN, K.M.*; ROUSE, G.; Scripps Institution of Oceanography; Scripps Institution of Oceanography kdorgan@ucsd.edu Recent work has shown that a range of polychaete annelids extend burrows through muddy sediments by fracture. Beach sands, however, are non-cohesive granular materials with different mechanics than […]
Migration in three dimensions Flight altitudes of small migratory birds
Meeting Abstract 43.5 Thursday, Jan. 5 Migration in three dimensions: Flight altitudes of small migratory birds BOWLIN, M.S.*; ENSTROM, D.A.; COCHRAN, W.W.; COCHRAN, J.; Univ. of Michgan-Dearborn; Illinois Natural History Survey; Illinois Natural History Survey; JDJC Corp. melissabowlin@gmail.com Small migratory birds use approximately one third of their energy budget during migration on flight; most of the mortality […]
Inertial and Fluid Forces during Bat Flight Maneuvers
Meeting Abstract 43.2 Thursday, Jan. 5 Inertial and Fluid Forces during Bat Flight Maneuvers BERGOU, AJ*; FRANCK, J; REIMNITZ, L; RISKIN, D; TAUBIN, G; SWARTZ, S; BREUER, K; Brown University attila_bergou@brown.edu Flying animals generate forces and torques to move through the air by coordinating the movement of their wings. Bats have evolved a particularly impressive capacity for […]
Flying in two dimensions
Meeting Abstract 43.3 Thursday, Jan. 5 Flying in two dimensions PRAKASH, Manu*; DONALD, Kim; Stanford University ; Stanford University manup@stanford.edu Surface of a pond provides an ecological niche which is exploited by a large number of species capable of locomotion on a fluid interface. Here we describe the discovery of constrained flight in two dimensions as a […]
