Meeting Abstract 24.4  Monday, Jan. 4  Stochastic Population Dynamics of a Desert Lizard ADOLPH, S.C.**; DAVIS, A.R.; FEDEROWITZ, M.; PETERSEN, J.; Harvey Mudd College; University of California, Berkeley; Harvey Mudd College; Harvey Mudd College adolph@hmc.edu Desert organisms experience highly variable precipitation, which can strongly affect reproduction and therefore population dynamics. In the viviparous desert night lizard (Xantusia […]

Meeting Abstract 24.5  Monday, Jan. 4  Emersion limits short term growth rates in intertidal Nucella lamellosa PRICE, RM*; ELAHI, R; Univ. of Washington, Bothell; Univ. of Washington, Seattle becca.price@uwb.edu Many environmental factors affect the growth of marine invertebrates, but the way these factors interact remains poorly understood. For example, tidal emersion may limit the size of intertidal […]

Meeting Abstract 24.1  Wednesday, Jan. 5  Speciation, in the sea? DAWSON, MN; University of California, Merced mdawson@ucmerced.edu The fluid mechanics of marine and terrestrial systems are surprisingly similar at many spatial and temporal scales. Not surprisingly, the dispersal of organisms that float, swim, or fly is influenced by the fluid environments of air and seawater. Nonetheless, it […]

Meeting Abstract 24.3  Wednesday, Jan. 5  Patterns of speciation in sea cucumbers MICHONNEAU, Francois; University of Florida francois.michonneau@gmail.com Despite their striking presence on coral reefs and the multi-millon dollar industry targeting them, aspidochirotid holothurians have received relatively little taxonomic attention. Heavy reliance on ossicles has lead to a confused taxonomy and masks substantial cryptic diversity. As part […]
