Meeting Abstract 41-2  Tuesday, Jan. 5 08:15  Niche constructed shells are built for locomotion: enhanced mobility, in the sea and on land, by terrestrial hermit crabs TRINH, R. C.*; LAIDRE, M. E.; University of California, Berkeley; Dartmouth College fish.r.awsome@gmail.com Species vary enormously in their locomotory ability. For shell-bearing organisms, like hermit crabs and gastropods, locomotion may be […]

Meeting Abstract 41-5  Tuesday, Jan. 5 09:00  Mechanism of early hatching of hourglass treefrogs in drying and ant attacks COHEN, KL*; WARKENTIN, KM; Boston University kcohen@bu.edu http://sites.bu.edu/warkentinlab/ Embryos of many species adaptively alter hatching timing in response to environmental cues. Most frogs hatch by secreting hatching enzyme from unicellular hatching glands (HG) on the epithelium, but mechanistic […]

Meeting Abstract 41-1  Tuesday, Jan. 5 08:00  Endurance capacity and home range size in Desert Iguanas (Squamata: Dipsosaurus dorsalis) SINGLETON, J.M.*; GARLAND, JR., T.; Univ. of California, Riverside jsing014@ucr.edu Interspecific comparisons have yielded insight into regarding relationships between field locomotor behavior and performance capacities. Among species of lizards, endurance capacity measured on a motorized treadmill is positively […]

Meeting Abstract 40-5  Tuesday, Jan. 5 09:00  What a Long Strange TRiP: Molecular and Neural Mechanisms of Thermal “Vision” in Pit Vipers and Pythons GRACE, M.S.*; MCLAMB, W.T.; Florida Institute of Technology; Florida Institute of Technology mgrace@fit.edu Boid and crotaline snakes (boas, pythons and pit vipers) image their worlds simultaneously in two very different regions of the […]

Meeting Abstract 40-1  Tuesday, Jan. 5 08:00  System identification of flower tracking in three species of hawkmoths reveals interspecific tuning of motor control to visual ecology SPONBERG, S.N.*; STöCKL, A.; Georgia Inst. of Tech; Lund University sponberg@physics.gatech.edu http://sponberg.gatech.edu Animals must maintain maneuverability despite difference in sensory ecology. Both sensory and motor conditions vary widely both across species […]

Meeting Abstract 40-2  Tuesday, Jan. 5 08:15  Modeling and measuring perceptual color distances in anoline lizards FLEISHMAN, L.J.; Union College fleishml@union.edu Anolis lizards communicate with colorful throat fans known as dewlaps. Dewlaps come in a wide variety of colors and our research has focused on trying to explain the evolution of this diversity. We assume that dewlap […]

Meeting Abstract 40-3  Tuesday, Jan. 5 08:30  Hummingbirds visually control forward flight using image features instead of image pattern velocity DAKIN, R*; FELLOWS, TK; ALTSHULER, DL; University of British Columbia; University of British Columbia; University of British Columbia roslyn.dakin@gmail.com http://www.roslyndakin.com Optic flow can provide information about the distance between an observer and passing obstacles. It has been […]

Meeting Abstract 40-7  Tuesday, Jan. 5 09:30  Haltere influence on gaze control in tethered Drosophila flight THANIGAIVALEN, I*; MURELI, S; FOX, JL; Case Western Reserve University; Case Western Reserve University; Case Western Reserve University jlf88@case.edu Animal behavior requires the integration of multiple sensory information streams. For flying animals, stability and control require the rapid integration of visual […]
