Meeting Abstract 64.2 Friday, Jan. 6 A new Sipuncula classification: reassessing and dating the sipunculan phylogeny using a six-gene dataset and fossil taxa KAWAUCHI, Gisele Y.*; SHARMA, Prashant P.; GIRIBET, Gonzalo; Harvard University, Cambridge; Harvard University, Cambridge; Harvard University, Cambridge gykawa@gmail.com Sipuncula is a protostome phylum of contentious phylogenetic placement and an elusive internal phylogeny. Repeated attempts […]

When wings collide how collisions cause wing wear in bees and wasps
Meeting Abstract 64.3 Saturday, Jan. 5 When wings collide: how collisions cause wing wear in bees and wasps MOUNTCASTLE, AM*; COMBES, SA; Harvard University mountcastle@fas.harvard.edu Many flying insects suffer periodic wing damage and exhibit a cumulative loss of wing area over their lifespan. Wing area loss reduces aerodynamic force production, load carrying capacity and flight maneuverability, and […]
Roll-based sideways motion of mosquitoes in free flight
Meeting Abstract 64.1 Saturday, Jan. 5 Roll-based sideways motion of mosquitoes in free flight IAMS, SM*; BEATUS, T; GUCKENHEIMER, J; COHEN, I; Bowdoin College & Cornell University; Cornell University; Cornell University; Cornell University smi6@cornell.edu The mosquito body plan and flight characteristics are qualitatively different than those of other well-studied Dipterans. Mosquitoes have a long and slender body, […]
On the flight of foraging bumblebees in the near-wake of objects
Meeting Abstract 64.2 Saturday, Jan. 5 On the flight of foraging bumblebees in the near-wake of objects RAVI, S*; CRALL, J; COMBES, S; Harvard University; Harvard University; Harvard University sravi@fas.harvard.edu The high energy demands of a growing hive require bees to forage relentlessly, even under unfavorable weather conditions such as cool temperatures, precipitation or high winds. Bees […]
Found or Fly flight, reproduction and biomechanical tradeoffs in ant queens
Meeting Abstract 64.5 Saturday, Jan. 5 Found or Fly: flight, reproduction and biomechanical tradeoffs in ant queens HELMS IV, J.A.*; KASPARI, M.; University of Oklahoma; University of Oklahoma jackson.a.helms-1@ou.edu Because of a diversity of reproductive strategies, the ants [Formicidae] are an ideal system to study reproductive tradeoffs. In a typical species, a young queen performs two competing, […]
Flight with Winglets in Stick Insects
Meeting Abstract 64.4 Saturday, Jan. 5 Flight with Winglets in Stick Insects ZENG, Y*; NUNNS, H; DUDLEY, H; Univ. of California, Berkeley; Univ. of California, Berkeley; Univ. of California, Berkeley dreavoniz@berkeley.edu The stick insects (Insecta: Phasmatodea) exhibit remarkable variation in wing size and flapping kinematics across a wide spectrum of aerial performance, from flapping flight to complete […]
Aerial behaviors in wingless canopy arthropods
Meeting Abstract 64.6 Saturday, Jan. 5 Aerial behaviors in wingless canopy arthropods YANOVIAK, S. P.*; DUDLEY, R.; University of Louisville; University of California, Berkeley steve.yanoviak@louisville.edu Gliding flight occurs in a wide range of vertebrate taxa, but was unknown for wingless terrestrial arthropods until it was reported for ants of the tropical rainforest canopy in 2005. Here we […]
Warmer spring temperatures predict earlier summer molt in a songbird
Meeting Abstract 64.4 Monday, Jan. 6 08:45 Warmer spring temperatures predict earlier summer molt in a songbird BUTLER, L.K.*; HOPE, S.; STABILE, F.; OUELLETTE, M.; The College of New Jersey, Ewing lbutler@tcnj.edu The atmosphere has warmed significantly at northern latitudes over the past century, and understanding effects of this climate change on life is a major concern […]
