Meeting Abstract 28.5  Friday, Jan. 4  Variability in Larval Provisioning and its effects on Juvenile Size and Survivorship in Four Bryozoan Species KOSMAN, E*; PERNET, B; California State University, Long Beach etkosman@yahoo.com There are few estimates of the magnitude or partitioning of variation in offspring size (as a measurement of per-offspring investment, POI) in marine invertebrates. Yet, […]

Meeting Abstract 28.3  Friday, Jan. 4  Polar gigantism in marine invertebrates: a test of the oxygen constraint hypothesis using temperate and Antarctic Tritonia egg masses WOODS, HA*; MORAN, AL; Univ. Montana; Clemson Univ. art.woods@mso.umt.edu Among marine ectotherms, high-latitude species are often larger-bodied than their low-latitude relatives, a phenomenon known as �polar gigantism.� One mechanistic explanation invokes cold-driven […]

Meeting Abstract 28.2  Friday, Jan. 4  In situ measurement of oxygen in aquatic egg masses: field tests of theoretical models MORAN, A.L.**; WOODS, H.A.; Clemson Univ.; Univ. of Montana, Missoula moran@clemson.edu Aquatic, gelatinous egg masses occur in a wide range of organisms, and physiological models of oxygen demand (by embryos within masses) and oxygen supply (by diffusion) […]

Meeting Abstract 28.1  Friday, Jan. 4  Extended starvation resistance and subsequent growth recovery in sea urchin larvae: Implications for lifespan in the plankton YU, P. C.*; MANAHAN, D.T.; University of Southern California; University of Southern California pcy@usc.edu Food availability has a major influence on growth rates of feeding stages of larvae. Variability in oceanic food availability is […]

Meeting Abstract 28.4  Friday, Jan. 4  Declining Reproductive Output of the Blue Crab, Callinectes sapidus: A Changing Reaction Norm? WELLS, S.L.*; MCCONAUGHA, J.R.; Old Dominion University; Old Dominion University swells@odu.edu In recent years there has been a reduction in the spawning stock of the Chesapeake Bay blue crab population, as well as lower than expected female reproductive […]

Meeting Abstract 28.1  Monday, Jan. 5  Vicariance or pseudocongruence? Evidence from a multi-species break in the northeastern Pacific MCGOVERN, TM*; KEEVER, CC; HART, MW; SASKI, CA; COX, LN; EMME, SA; HOFFMAN, JM; MARKO, PB; Clemson Univ.; Simon Fraser Univ.; Simon Fraser Univ.; Clemson Univ.; Clemson Univ.; Clemson Univ.; Clemson Univ.; Clemson Univ. tmcgove@clemson.edu Comparative phylogeography often reveals […]

Meeting Abstract 28.5  Monday, Jan. 5  Polar Gigantism in Antarctic Invertebrates: Sizing up the Role of Temperature-Oxygen Interactions MORAN, A.L.**; WOODS, H.A.; Clemson Univ., SC; Univ. of Montana, Missoula moran@clemson.edu Polar gigantism, the trend among some marine invertebrates towards large body sizes at high latitudes, is not clearly understood in ecological or evolutionary terms. One hypothesis is […]

Meeting Abstract 28.3  Monday, Jan. 5  Molecular phylogeography of three Southern Ocean species in the genus, Odontaster (Odontasteridae; Asteroidea) separated by the Drake Passage JANOSIK, A.M*; MAHON, A.R.; HALANYCH, K.M; Auburn University, Auburn, AL; University of Notre Dame, Notre Dame, IN; Auburn University, Auburn, AL janosam@auburn.edu Many marine invertebrates that possess a life history characterized by a […]

Meeting Abstract 28.2  Monday, Jan. 5  Large scale shrinkage: climate change and distributional contractions of Mytilus JONES, S.J.*; WETHEY, D.S.; Univ. of S. Carolina, Columbia; Univ. of S. Carolina, Columbia sierra@biol.sc.edu Intertidal ecosystems are physically rigorous habitats which may serve as models for the effects of climate on biogeography. Organisms residing in the intertidal zone are exposed […]

Meeting Abstract 28.4  Monday, Jan. 5  Connectivity Patterns of Two Hawaiian Marine Gastropods Posessing Nonpelagic Development CHANEY, N.L.*; DEMAINTENON, M.J.; University of Hawaii, Hilo; University of Hawaii, Hilo chaney@hawaii.edu Connectivity of benthic marine gastropods in Hawaii is poorly understood due to the lack of extensive studies. In species lacking a pelagic larval phase, connectivity between populations would […]
