Meeting Abstract S7-2.1  Sunday, Jan. 6  Egging each other on: embryonic communication in a nest maintains circadian rhythms of heart rate in turtles? LOUDON, FK; SPENCER, R-J*; University of Western Sydney, Australia r.spencer@uws.edu.au Amniotic eggs provide model organisms to explore the embryonic development of endogenous physiological circadian rhythms without the influence of maternal biorhythms. Recent studies have […]

Meeting Abstract S7-1.5  Sunday, Jan. 6  What the clock tells the eye: Lessons from an ancient arthropod BATTELLE, Barbara-Anne; Univ, of FL, Whitney Laboratory for Marine Bioscience Battelle@whitney.ufl.edu Eyes are major targets for regulation by circadian clocks, but effects of circadian clocks on vision are not fully understood in any system. Among invertebrates, effects of circadian rhythms […]

Meeting Abstract S7-1.6  Sunday, Jan. 6  Synchronization of circadian bioluminescence as a group-foraging strategy in cave glowworms MERRITT, DJ*; MAYNARD, AJ; The University of Queensland, Australia; The University of Queensland, Australia d.merritt@uq.edu.au Flies of the genus Arachnocampa are sit-and-lure predators that use bioluminescence to attract flying prey to their silk webs. Some species are most common in […]

Meeting Abstract S7-1.3  Sunday, Jan. 6  Rhythmic Ring-Ring Stacking Drives the Circadian Oscillator Clockwise LIWANG, A.*; CHANG, Y.-G.; TSENG, R. D.; University of California, Merced; University of California, Merced; University of California, Merced aliwang@ucmerced.edu The oscillator of the circadian clock of cyanobacteria is composed of three proteins, KaiA, KaiB, and KaiC, which together generate a self-sustained circadian […]

Meeting Abstract S7-1.1  Sunday, Jan. 6  Metazoan circadian rhythm: an universal “Zeitgeber” existing from sponges to humans MÜLLER, W.E.G. *; WANG, X.H. ; University Medical Center, Mainz, GERMANYz.de); University Medical Center, Mainz, GERMANY wmueller@uni-mainz.de In higher metazoans, the 24 h periodicity in the environment contributed to the evolution of the molecular circadian clock. We studied the circadian […]

Meeting Abstract S7-1.4  Sunday, Jan. 6  Finding A Temporal Niche DE LA IGLESIA, Horacio O.; SMARR, B.*; University of Washington; University of Washington horaciod@uw.edu Ecologists and physiologists are familiar with Hutchinson’s notion of ecological niche, the multidimensional space delineated by the range of resources in which a species survives and reproduces. Yet, few of us are used […]

Meeting Abstract S7-1.7  Sunday, Jan. 6  Evolution of animal clock: an echinoderm prospective OLIVERI, P*; PETRONE , L; LERNER, A; MATTIELLO, T; University College London p.oliveri@ucl.ac.uk Almost all living organisms show circadian rhythmicity. Endogenous time-keeping mechanisms that regulate daily physiological and behavioral processes are genetically encoded and show a conserved network structure. Comparative studies highlighted a transcriptional-translational […]

Meeting Abstract S7-1.2  Sunday, Jan. 6  Circadian clock of the starlet sea anemone Nematostella vectensis: a conserved network and missing links REITZEL, A.M.*; TARRANT, A.M.; Univ. of North Carolina, Charlotte; Woods Hole Oceanographic Inst. areitzel@whoi.edu The molecular components of the circadian clocks of mammals and diverse insects have been well-characterized, revealing that many of the core clock […]

Meeting Abstract S6-2.4  Sunday, Jan. 6  The effects of changing nutrient inputs on sexual selection dynamics and life history evolution SNELL-ROOD, EC*; MOREHOUSE, NI; University of Minnesota; University of Pittsburgh emilies@umn.edu Discussions of rapid human-induced environmental change often focus on the loss or disruption of critical resources, such as habitat destruction, pesticide contamination or drought in the […]

Meeting Abstract S6-2.2  Sunday, Jan. 6  Plasticity, selection, and the potential for adaptation in newly established populations GHALAMBOR, C.K.*; HANDELSMAN, C.A.; RUELL, E.W.; Colorado State. Univ.; Colorado State. Univ.; Colorado State. Univ. cameron1@colostate.edu Novel environments often impose directional selection for a new phenotypic optimum. However, new environments can also be a source of phenotypic variation by inducing […]
