Meeting Abstract 29.6  Friday, Jan. 4  Competition and Biogeography of Freshwater Mussels LEVINE, TD; Miami University levinetd@muohio.edu Unionid mussels constitute a highly threatened taxon, which achieve their greatest diversity in North America. To effectively conserve freshwater mussels it is necessary to understand their basic ecology. Recent theoretical models have demonstrated that mussels may interact competitively during their […]

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 27.7  Friday, Jan. 4  The role of badge size, bite performance and display behavior in predicting dominance in male ornate tree lizards. MEYERS, J.J.*; IRSCHICK, D.J.; University of Massachusetts, Amherst; University of Massachusetts, Amherst jmeyers@bio.umass.edu Social dominance among males has a profound effect on fitness in many species. Yet the characteristics that make up winners […]

Meeting Abstract 27.2  Friday, Jan. 4  Sexual selection and functional morphology: A new frontier? IRSCHICK, Duncan J; University of Massachusetts at Amherst irschick@bio.umass.edu Sexual selection has been studied for many decades, yet many of its central theories remain unresolved, in large part because of the difficulty of resolving issues of male quality and female choice. An emerging […]
