Meeting Abstract 49.1  Jan. 6  the effect of summer storms on the recruitment success of fiddler crabs BRODIE, R. *; GODLEY, J.; Mount Holyoke College rbrodie@mtholyoke.edu The estuarine fiddler crabs, Uca minax, U. pugnax and U. pugilator, have complex life cycles spanning vastly different salinity regimes. Larvae are spawned in estuaries and travel to the coastal ocean […]

Meeting Abstract 49.8  Jan. 6  Tolerance of the Early Life History Stages of to Environmental Conditions: Possible Limits to Dispersal SMART, T.I.; University of Oregon tsmart@uoregon.edu Exposure to extreme environmental conditions has been shown to cause lethal and sub-lethal effects on survival and development in marine invertebrates, affecting both dispersal and abundance. is a tube-building polychaete found […]

Catolica de Chile; Station Biologique de Roscoff; Pont. Univ. Catolica de Chile abrante@bio.puc.cl Sibling cannibalism during intracapsular development is a common strategy observed across different marine invertebrate taxa. It is still an open question […]

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, […]
