Meeting Abstract 120.5 Saturday, Jan. 7 Is GABA an Inhibitory Neurotransmitter in the Neural Circuit Regulating Metamorphosis in Ilyanassa obsoleta? BISCOCHO, D. *; LEISE, E.M.; University of North Carolina Greensboro; University of North Carolina Greensboro esther_leise@uncg.edu Metamorphosis in the marine mud snail, Ilyanassa obsoleta, is an irreversible biological event by which larvae metamorphose into sexually immature juveniles […]
High genotype-dependent mortality at metamorphosis in the Pacific oyster
Meeting Abstract 120.2 Saturday, Jan. 7 High genotype-dependent mortality at metamorphosis in the Pacific oyster PLOUGH, L.V*; HEDGECOCK, D.; University of Southern California; University of Southern California lplough@usc.edu Settlement and metamorphosis is a critical period in the life cycle of marine invertebrates, during which larvae undergo substantial morphological, sensory, and genetic changes regulated by distinct developmental processes. […]

Wet mammals shake at tuned frequencies to dry
Meeting Abstract 119.2 Saturday, Jan. 7 Wet mammals shake at tuned frequencies to dry HU, David*; DICKERSON, Andrew; MILLS, Zack; Georgia Institute of Technology; Georgia Institute of Technology; Georgia Institute of Technology hu@me.gatech.edu In cold wet weather, mammals face hypothermia if they cannot dry themselves. By rapidly oscillating their bodies for fractions of a second, hirsute mammals […]
