ROBBINS, T.R.*; WARNER, D.A.; University of South Florida; The University of Sydney: Fluctuations in the incubation environment: Does the pattern or magnitude influence egg survival and hatchling phenotypes in a lizard? Environmental and maternal factors can shape offspring phenotypes in ways that could influence offspring survival and fitness. Most studies that evaluate environmental effects on […]

WESTERMAN, E.L.*; HARRIS, L.G.; University of New Hampshire; University of New Hampshire: Environmentally caused changes in asexual reproduction rates in two invasive sea squirts: Botryllus schlosseri and Botrylloides violaceus An increase in global ocean temperatures over the last century has coincided with an increase in invasive species. Ascidians have been particularly successful as invaders and […]

SCHMIDT, K. *; STARCK, J.M.; Ludwig-Maximilians-University of Munich; Ludwig-Maximilians-University of Munich: Developmental plasticity vs. phylotypic constraints during early embryogenesis of zebra fish, Danio rerio During the phylotypic stage vertebrate embryos pass through a period of morphological similarity. In zebra fish, Danio rerio, multiple correlations among characters stabilize morphology during the phylotypic stage, but a considerable […]

Meeting Abstract 4.2  Jan. 4  Potential speciation in anchialine environments: the roles of life history and geology SANTOS, S.R.; Auburn University santos@auburn.edu Anchialine habitats, land-locked bodies of mixohaline water that fluctuate with the tides but have no surface connection to the sea, are known from around the world. A wide variety of organisms exploit anchialine environments, with […]

Meeting Abstract 4.3  Jan. 4  Is visual performance constrained by body size in Drosophila melanogaster? MERRY, J. W.*; RUTOWSKI, R. L.; Arizona State University; Arizona State University jmerry@asu.edu Past research on insect eyes has revealed the presence of a strong, allometric relationship between eye size and body size, both within and among species. This finding has been […]

Meeting Abstract 4.3  Thursday, Jan. 3  Visual Target Detection in Damselflies SCHROEDER, R.*; BUTLER, M.A.; University of Hawaii, Honolulu; University of Hawaii, Honolulu rolandsc@hawaii.edu How insects are able to detect targets of interest remains a critical question. Their visual system consists of relatively small compound eyes with no focusing mechanism, limited stereoscopic vision, and low resolution. However, […]
