ALLMAN, Andrea/L*; PLACE, Allen/R; Center of Marine Biotechnology, Baltimore MD: The effect of dietary chitin and cellulose on growth and digestive enzyme production in the juvenile blue crab, Callinectes sapidus. Blue crab (Callinectes sapidus (Rathbun)) hatchery technology is being developed at the Center of Marine Biotechnology (Baltimore, MD). To more efficiently produce juveniles and adults […]

MARKLEY, J.S.*; CARRIER, D.R.; University of Utah; University of Utah: The cost of ventilation in birds The exceptional aerobic performance of some birds is often attributed, in part, to the unusual way birds breathe. Movements of the sternum are thought to be primarily responsible for ventilation. Gravity acting on the mass of the sternum, associated […]

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 […]

BREAKER, Rioshannon*; HERNANDEZ, Jazmir; WILLIAMS, Judith; Univ. of Southern Miss Gulf Coast; Univ. of Southern Miss Gulf Coast; Univ. of Southern Miss Gulf Coast: The Expression of PBAN-like Peptides in Two Ontogenetic Stages of the Commercial White Shrimp Litopenaeus setiferus From The Gulf of Mexico Pheromone biosynthesis activating neuropeptide (PBAN) is a well characterized insect […]

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 […]
