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 […]

ARONOWICZ, J.*; LOWE, C.J.; University of Chicago; University of Chicago: The midbrain-hindbrain gene expression profile in Saccoglossus kowalewskii The diffuse nervous system of the direct developing hemichordate Saccoglossus kowalewskii shares many of its remarkably complex anterior posterior patterns of developmental gene expression with vertebrates. Recent studies in larvaceans, tunicates and amphioxus indicate that the complex […]

TUBLITZ, NJ; University of Oregon: Mechanisms underlying peptide mediated neuroplasticity: A spineless approach in moths, flies and cephalopods. This talk discusses 4 separate mechanisms underlying peptide mediated neuroplasticity that have evolved in several invertebrates. The first is at the cellular level in the moth Manduca sexta. Manduca has a set of larval neurons that express […]

LOWE, CJ*; ARONOWICZ, J; TERASAKI, M; KIRSCHNER, M; GERHART, J; University of Chicago; University of Chicago; University of Connecticut; Harvard Medical School; University of California Berkeley: Hemichordate development and the evolution of chordate nervous system How the chordate central nervous system evolved from their invertebrate ancestors has a long history in evolutionary biology, yet it […]

CAIN, Shaun D.*; CHRISTIE, Andrew E.; Univ. of Washington, FHL; Univ. of Washington, FHL: Distribution of NOS-like immunoreactivity within the Nudibranchia Within the invertebrates, the gaseous neurotransmitter nitric oxide (NO) has been shown to mediate a variety of behavioral pathways. Although there is evidence that NO functions in some sensory systems, the majority of studies […]

MURRAY, JA; U Central Arkansas: Advances in the neural bases of orientation & navigation The ability to locomote in one direction, and the ability to navigate toward a distant goal are related behaviors that are phylogenetically widespread. Orientation includes finding the source of a signal, or movement relative to directional cues. Such abilities may require […]
