MCCOY, A.M.; Harvard University: Predicting Biological Invasions: Using Microbes for Highly Specific Predictive Ability Despite recognition of the potential ecological consequences of biological invasions, factors that determine when a particular invasive will be successful remain largely unknown. Many species in the marine environment rely on specific interactions with microbes for a variety of processes including […]

GONZALEZ, V; PEPINO, N; VALERO, S; BOHONAK, A; SIMOVICH, M; U. San Diego; U. San Diego; San Diego State Univ.; San Diego State Univ.; U. San Diego: Polymorphic microsatellite loci for threatened anostracan and related species. Extensive habitat loss in Southern California has resulted in severe decreases in population numbers and possibly declines in genetic […]

MCMULLIN, E.R.; MARSH, A.G.; University of Delaware, Lewes, DE: Poecilogony in the polychaete Streblospio benedictii: incipient speciation or maintained polymorphism? Most benthic marine invertebrate species exhibit only a single developmental mode. Poecilogony, or the occurrence of multiple developmental modes within a species, is very rare, and molecular genetic studies often reveal suspected cases to be […]

CERASALE, D.J.; GUGLIELMO, C.G.; University of Montana; University of Montana: Plasma phospholipid levels and triglyceride:phospholipid ratio as indicators of mass change and diet lipid quality in wild birds Plasma metabolite profiling has received recent attention as a means to assess body mass changes in migratory birds. Prior studies have focused on triglycerides as the main […]

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 […]
