SHIKUMA, N. J.; HADFIELD, M. G. ; Univ. of Hawaii; Univ. of Hawaii: Revealing bacterial biofilm community composition and its role in inducing metamorphosis of the tubeworm Hydroides elegans The succession of sessile biofouling invertebrates is known to occur around the world, however the mechanisms behind this phenomenon have yet to be explained. Specific cues […]

JANES, D.E.; WAYNE, M.L.; Harvard Univ.; Univ. of Florida: Quantitative Genetic Variation in Sex-Determining Response to Incubation Temperature in Leopard Geckos Among vertebrates, sex is determined by one of two recognized mechanisms: environmental or genetic sex determination in which sex is determined by incubation environment or genetic contribution of parents, respectively. The adaptiveness of one […]

LEBLANC, A.M.*; ROSTAL, D.C.; WIBBELS, T.; Georgia Southern University; Georgia Southern University; University of Alabama at Birmingham: Natural Pivotal Temperature and Sex Ratios of Loggerhead Sea Turtles (Caretta caretta) Nesting on Two Georgia Barrier Islands Temperature-dependent sex determination was studied in loggerhead sea turtles (Caretta caretta) nesting on two Georgia barrier islands during the 2000-2003 […]

ARONOWSKY, A; AGNEW, J. G.; LEIGHTON, L. R.; ANDERSON, L. C.; Louisiana State Univ.; Louisiana State Univ.; San Diego State Univ.; Louisiana State Univ.: Inferring predation intensity on heterochelous decapod crustaceans: simulation studies and the handedness metric. Decapod crustaceans are well known as major predators in marine ecosystems but less attention is paid to their […]

TURNBULL, CA; DEARING, MD; ST. JEOR, S; Univ. of Utah; Univ. of Utah; Univ. of Nevada, Reno: Effects of species diversity on dynamics of Sin Nombre Hantavirus in deer mice (Peromyscus maniculatus) Species diversity has been suggested to impact disease prevalence; however, two leading hypotheses predict divergent outcomes. The �Dilution Effect� predicts that higher species […]

JOHNSON, C.H.; WENDT, D.E.; Cal Poly, San Luis Obispo; Cal Poly, San Luis Obispo: Does dissolved organic matter (DOM) offset the costs of an extended larval swimming phase for the marine bryozoan Bugula neritina? It is well known that dissolved organic matter (DOM), in the form of carbohydrates, lipids, and free amino acids, is an […]

HORISAWA, S.*; DUDLEY, R.; Univ. of California, Berkeley; Univ. of California, Berkeley: Three-Dimensional Wing Kinematics of Erratic Flight in Free-Flying Butterflies Many insects can fly erratically. In particular, it is well known that butterflies exhibit erratic, irregular, and unpredictable flight paths which might help in evading attack from aerial predators. Palatability of butterflies is correlated […]

MYHRVOLD, C.*; SANE, S.; DANIEL, T.; Univ. of Washington, Seattle; Univ. of Washington, Seattle; Univ. of Washington, Seattle: The flexible halteres of the cranefly Holorusia rubiginosa Animal locomotion requires navigation. As such, animals have evolved a variety of navigational devices, which often take the form of inertial sensors. Because they move in three dimensions, flying […]

SPONBERG, S.*; SPENCE, A.; FULL, R.J.; Univ. of CA, Berkeley; Univ. of CA, Berkeley; Univ. of CA, Berkeley: Testing Neural Control Models for Antenna-based Tactile Navigation in Cockroaches Navigation requires neural sensing of environmental features. Cockroaches use antennal tactile contact to track walls during running in low light environments. A kinematic response to wall turning […]
