BERTING, J.I.*; KINSEY, S.T.; University of North Carolina Wilmington: The Response of Myoglobin Concentration to Chronic Hypobaric Hypoxia is Strain Specific in Mice Myoglobin is the final mediator of oxygen flux from the atmosphere to the mitochondria in the oxygen delivery cascade, and is the only component of the cascade that is intracellular. Because myoglobin�s […]

CERICOLA, Vincent*; DANIEL, Peter; Hofstra University; Hofstra University: The Phylogeny of Antennular Grooming Behavior in Decapod Crustaceans Crustaceans groom their olfactory organ, the antennules, by wiping it through a pair of mouthpart appendages. Among reptantian decapods, glutamate (Glu), a chemical found in prey, stimulated AGB in the 4 lobster species but not the one crab […]

HARDY, KM**; KINSEY, ST; Univ. of North Carolina Wilmington; Univ. of North Carolina Wilmington: The Effects of Cell Size on Post-Contractile Arginine Phosphate Recovery and Glycogen Depletion in the Blue Crab, Callinectes sapidus Anaerobic (light) muscle fibers that power swimming in the juvenile blue crab, Callinectes sapidus, exhibit cell diameters of

FLY, E.K.**; BURNAFORD, J.L.; TULLIS, A.; University of Puget Sound, Tacoma, WA; University of Puget Sound, Tacoma, WA; University of Puget Sound, Tacoma, WA: Temperature effects on the metabolism and microhabitat choice of the keystone predator Pisaster ochraceus The sea star Pisaster ochraceus strongly impacts the distribution and abundance of its prey species in the […]

ERICKSON, J.R.*; SIDELL, B.D.; MOERLAND, T.S.; Florida State University; University of Maine, Orono; Florida State University: Temperature Sensitivity of Magnesium Affinity for Parvalbumins Isolated from Teleost Fish Parvalbumin (PV), a small acidic protein expressed abundantly in fast-twitch muscle, can bind two calcium or magnesium ions with high affinity. The dissociation constant (KD) of Mg2+ was […]

BUSKIRK, MC*; HAHN, DA; Univ. of Florida; Univ. of Florida: Starvation reveals critical larval body size for adult development in the flesh fly, Sarcophaga crassipalpis. Documenting the regulation of cellular growth and proliferation during development is essential for understanding both normal ontogeny and disease phenotypes. Diapause-destined individuals of the flesh fly Sarcophaga crassipalpis grow substantially […]

ST MARY, CM*; LINDSTR�M, K; University of Florida; University of Helsinki: Stabilizing and directional selection acting on male parental care Life-history theory argues that there exists a trade-off between investment in parental care and mate attraction when males provide parental care. However, when females use care in mate choice, parental care also functions in mate […]

HARPER, F.M.; POMERLAU, E.A.; RAWSON, P.D.*; Rollins College; University of Maine, Orono; University of Maine, Orono: Species-specific egg-borne proteins in the blue mussels, Mytilus edulis and M. trossulus Several gamete recognition systems have been recognized for their roles in conspecific fertilization and gamete compatibility in marine invertebrates. In blue mussels, divergence in the amino acid […]

SCHWARZ, Ryan S.*; CADAVID, Luis F.; University of New Mexico; University of New Mexico: Somatic cell parasitism and the evolution of histocompatibility systems Colonial invertebrates have the ability to discriminate between self-tissues and those of unrelated members of their own species. Histocompatibility reactions typically result in either fusion or rejection. A highly polymorphic gene complex […]
