CHAMPAGNE, CD*; HOUSER, DS; CROCKER, DE; Sonoma State University; Sonoma State University; Sonoma State University: Physiological Adaptations to Fasting in northern elephant seals During prolonged fasting physiological mechanisms defend lean tissue from catabolism. In the fasting state, glucose is derived solely from gluconeogenesis, requiring some catabolism of amino acids for gluconeogenic substrates. This creates a […]

MAHON, H/K; DAUER, D/M; Old Dominion University: Particle Selection Dynamics of Surface Deposit Feeders: Roles of Particle Size, Organic Coating and Adaptive Morphologies Surface deposit-feeding polychaetes rely on a poor food source for energy and nutrients. Many deposit feeders have evolved mechanisms, such as particle selectivity, to increase sediment processing efficiency and maximize net energy […]

SAMARCO, Thomas, J; TURINGAN, Ralph, G; Florida Institute of Technology; Florida Institute of Technology: PREY CAPTURE KINEMATICS IN HATCHERY-REARED AND WILD RED DRUM, SCIAENOPS OCELLATUS: IMPLICATIONS FOR ENHANCEMENT OF WILD POPULATIONS Variation in environmental conditions may lead to morphological, physiological, biochemical, and behavioral differences among fish populations. In an attempt to explore the effects of […]

TAKEMAE, N.; NAKAYA, F.; MOTOKAWA, T.; Tokyo Institute of Technology; Tokyo Institute of Technology; Tokyo Institute of Technology: Oxygen consumption of catch connective tissue of the sea cucumber Actinopyga mauritiana (Echinodermata, Holothuroidea) Sea cucumbers show lower oxygen consumption rate per wet weight (VO2) compared to other animals of the same size. This has been attributed […]

MENON*, J.; MILITELLO, F. ; BUCHHOLZ, D. ; William Paterson University of New Jersey; William Paterson University of New Jersey; National Institute of Health: Oxidative stress during intestine remodeling in anuran tadpoles ,Xenopus laevis. Development of many animals is associated with excessive production of reactive oxygen species (ROS) and/or decreased antioxidant capacity. Formation ROS is […]

BRANSTETTER, M. G.; The Evergreen State College: Oil-collecting structures of the South African bee genus Rediviva (Hymenoptera, Mellitidae): An investigation using scanning electron microscopy Bees have been coevolving with flowering plants for millions of years and have as a result a wide range of adaptations for collecting many different types of floral rewards. In addition […]

OYARZUN, FX; University of Washington: Nurse eggs and cannibalism influence intracapsular development and survival in a poecilogonous spionid polychaete Poecilogony is the ability to alternate between multiple developmental modes. Boccardia proboscidea, a spionid polychaete, has three different types of developmental strategies, including one in which capsules have approximately 90% nurse eggs and a mixture of […]

CONNOLLY, M.H.*; HALL, B.K.; Dalhousie University, Halifax, NS; Dalhousie University, Halifax, NS: More than skin deep: tracing heat shock protein-90 expression to pigment and skeletal variation in Danio rerio More genetic variation is present than normally expressed in the phenotype, due in part to canalization. Using embryonic zebrafish (Danio rerio), this �hidden� variation is being […]
