Meeting Abstract 55.3  Tuesday, Jan. 5  Kinematics and control in free-flying hoverflies WALKER, S.M.**; THOMAS, A.L.R.; TAYLOR, G.K.; Oxford University; Oxford University; Oxford University simon.walker@zoo.ox.ac.uk Hoverflies show exquisite manoeuvrability while flying, yet we are still some way off from understanding how this level of control is achieved. Recently, we have found evidence that an accessory flight surface, […]

Meeting Abstract 53.5  Tuesday, Jan. 5  Oxygen-induced plasticity and evolution of larval tail morphology in stream and pond-breeding salamanders (genus Ambystoma) LANDBERG, Tobias; University of Connecticut tobias.landberg@uconn.edu Adaptive variation in larval ecotypes has evolved in five salamander families, but the environmental contributions to evolutionary differences are barely explored. Large gills and tail fins contribute to gas exchange […]

Meeting Abstract 53.1  Tuesday, Jan. 5  Larval Development and Metamorphosis of the Deep-Sea Cidaroid Urchin Cidaris blakei BENNETT*, K.C.*; EMLET, R.E.; YOUNG, C.M.; Oregon Institute of Marine Biology; Oregon Institute of Marine Biology; Oregon Institute of Marine Biology kbennet4@uoregon.edu Extant urchins are divided into two lineages, the Cidaroida and the Euechinoidea. Cidaroida, the order of “pencil urchins,” […]

Meeting Abstract 53.3  Tuesday, Jan. 5  Embryology of the red-backed salamander (Plethodon cinereus) KERNEY, Ryan; Dalhousie University, Halifax, NS ryankerney@gmail.com The red-backed salamander (Plethodon cinereus) is a locally common species from Northeastern United States and Eastern Canada. Like other members of its genus, P. cinereus is direct developing, and breeds terrestrially. Like other members of its family, […]
