Meeting Abstract 49.3  Jan. 6  Predator-Induced Morphological Defenses In Marine Zooplankton: A Larval Case Study VAUGHN, Dawn ; Univ. of Washington, Friday Harbor Laboratories dvaughn@u.washington.edu While there are numerous reports of predator-induced morphological defenses for benthic marine animals, freshwater zooplankton and freshwater larvae, at present there is an absence of studies demonstrating similar phenomena in adult marine […]

Meeting Abstract 49.7  Jan. 6  Larval Metamorphosis of Phestilla spp. in Response to Water Soluble Cues RITSON-WILLIAMS, R.*; PAUL, V.J.; Smithsonian Marine Station at Fort Pierce; Smithsonian Marine Station at Fort Pierce williams@sms.si.edu In marine systems many invertebrates depend on their larvae for dispersal and to find the appropriate habitat for adult survival, yet the mechanisms of […]

Meeting Abstract 49.2  Jan. 6  Impacts of food concentration and larval stage on incidence of cloning in Dendraster excentricus plutei MCDONALD, K.A.*; VAUGHN, D.; University of Washington, Friday Harbor Labs; University of Washington, Friday Harbor Labs kamcdon@u.washington.edu Asexual reproduction confers efficient use of limiting resources. Some freshwater plankters undergo a shift in reproductive mode in response to […]

Meeting Abstract 49.5  Jan. 6  Genome-Enabled Insight into Biogeographic Patterns of Marine Larval Thermotolerance FIELMAN, K.T.*; HOFMANN, G.E.; Auburn Univ.; UC, Santa Barbara fielman@lifesci.ucsb.edu The role of larval thermotolerance in setting marine species� biogeographic distribution and abundance patterns is unclear and little is known of the underlying genomic-scale molecular physiology. We compared heat shock survivorship among plutei […]

Meeting Abstract 49.10  Jan. 6  Egg mass physiology: Comparative morphology and physiology of experimental and natural invertebrate egg masses from temperate and Antarctic sites MORAN, A.L.**; WOODS, H.A.; Clemson University, Clemson, SC; University of Montana, Missoula moran@clemson.edu Embryos of many marine invertebrates are encased in gelatinous masses for part or all of development. Both experimental evidence and […]

Meeting Abstract 49.11  Jan. 6  Egg mass physiology: Interactive effects of morphology, temperature, and embryonic age on oxygen gradients in invertebrate egg masses WOODS, H.A.**; MORAN, A.L.; Univ. of Montana, Missoula; Clemson University, Clemson, SC art.woods@mso.umt.edu Embryos of many marine invertebrates are encased in gelatinous masses for part or all of development. Because gel retards oxygen flux, […]

Meeting Abstract 49.9  Jan. 6  Ecological stoichiometry of Manduca sexta herbivory on Datura wrightii. BARKER, JENNIFER S.**; HUXMAN, T.; BRONSTEIN, J.; DAVIDOWITZ, G.; University of Arizona; University of Arizona; University of Arizona; University of Arizona jbhepcat@email.arizona.edu Host plants can differ in quality among different habitats, among plants in the same microhabitats, as well as among leaves within […]

Meeting Abstract 49.6  Jan. 6  Attachment strengths of settling coral planulae. HADFIELD, M. G.*; DUBUC, T.; TRAN, C; University of Hawaii at Manoa; University of Hawaii at Manoa; University of Hawaii at Manoa hadfield@hawaii.edu The larvae of reef-forming corals must recruit to a world characterized by great surface complexity and turbulent water flow generated by ocean waves. […]

Meeting Abstract 48.10  Jan. 6  Why sub-optimal is optimal: a model of ectotherm thermal preferences MARTIN, T.L.; HUEY, R.B.*; Harvard Univ.; Univ. Washington, Seattle hueyrb@u.washington.edu Body temperature profoundly affects the fitness of ectotherms, and many ectotherms use behavioral adjustments in an attempt to control body temperatures within narrow, species-specific levels. Biologists have long assumed that such �preferred […]

Meeting Abstract 48.4  Jan. 6  Who’s hot and who’s not? Species-specific thermal histories may determine the biogeographies of Mytilid mussels in the US. JONES, S.J.*; MIESZKOWSKA, N.; WETHEY, D.S.; Univ. of S. Carolina, Columbia; Univ. of S. Carolina, Columbia; Univ. of S. Carolina, Columbia sierra@biol.sc.edu Most organisms have latitudinally discreet biogeographical distributions. While various factors may affect […]
