PAULAY, G.; MEYER, C. P.; University of Florida, Gainesville: Dispersal and divergence across the greatest ocean: Do larvae matter? For benthic taxa, the duration of larval planktonic period is expected to correlate with dispersal ability, and thus with the extent of species ranges, at least in settings where planktonic dispersal is necessary to reach available […]

MINER, BG; Univ. of California, Davis: A Tribute to Larry McEdward and an Introduction to the Symposium Dr. Larry McEdward was a leader in the fields of larval ecology and marine invertebrate life histories. In 2001, Dr. McEdward unexpectedly passed away. To honor Dr. McEdward, we have organized a symposium to review the recent advances […]

DEGNAN, S.M.*; DEGNAN, B.M.; University of Queensland, Australia; University of Queensland, Australia: The origin of the metazoan biphasic life cycle: new insights from an ancient phylum. The biphasic life cycle, characterised by metamorphosis from a pelagic larva to a benthic adult, is found throughout the Metazoa. So is sexual reproduction via eggs and sperm. Amidst […]

GEORGIOU, C.D.; University of Patras: Sclerotial morphogenesis in fungi is induced by oxidative stress Sclerotium-forming fungi are very important plant pathogens with great biological interest because they can be viewed as models of primitive morphogenesis. They differentiate by asexually producing sclerotia which are usually spherical bodies of aggregated hyphae. In spite of the biological, ecological […]

HE, Y; TANG, R; HAO, Y; STEVENS, R. D.; PEI, Z-M*; Duke University; Duke University; Duke University; Duke Medical Center; Duke University: Nitric Oxide Represses Arabidopsis Flowering Nitric oxide (NO) plays an important role in many physiological processes in animals, such as smooth muscle relaxation, neurotransmission, and immune stimulation. It has also been implicated that […]

BISHOP, C.D.*; PECHENIK, J; HADFIELD, M.G.; Kewalo Marine Laboratories, University of Hawaii; Tufts University, Boston; Kewalo Marine Laboratories, University of Hawaii: Metamorphosis: under stimulatory or inhibitory control? Environmentally dependent metamorphosis of marine invertebrate larvae is a dynamic process that integrates ontogeny with habitat selection. The capacity of many marine invertebrate larvae to survive and maintain […]

HODIN, Jason; Hopkins Marine Station: Expanding networks: a hypothesis for the evolution of metamorphosis Metamorphosis is a more or less radical morphological transition between two multicellular phases in an organism’s life cycle, often marking the passage from a pre-reproductive to a reproductive life stage. It generally involves major physiological changes and a shift in habitat, […]

SANTELICES, B.*; ALVARADO, J.L.; P. Universidad Cat�lica de Chile, Santiago; P. Universidad Cat�lica de Chile, Santiago: Applying the concept of metamorphosis to the crustose-to-erect thallus transition of macroalgae Metamorphosis is broadly defined as a more or less radical morphological change between two multicellular life stages within an organism life phase, often marking the transition from […]

Meeting Abstract S7-1.4.1  Jan. 6  The Neurobiology of Muscle Fatigue: 15 Years Later ENOKA, R.M.*; BARRY, B.K.; University of Colorado, Boulder; University of Colorado, Boulder enoka@colorado.edu Fifteen years ago, Stuart and Enoka published a review paper (J Appl Physiol 72: 1631-1648, 1992) on the neurobiology of muscle fatigue. The review emphasized that fatigue could be caused by […]

Meeting Abstract S7-1.1.2  Jan. 6  The Ionic Mechanism Underlying Postinhibitory Rebound in Clione limacina Swim Interneurons PIRTLE, T.J.*; SATTERLIE, R.A.; Abilene Christian University ; Univ. North Carolina, Wilmington Thomas.Pirtle@acu.edu Swimming locomotion in Clione limacina is produced by alternate dorsal-ventral flexions of its wing-like parapodia which are ultimately controlled by two groups of pedal interneurons that interact via […]
