GUGLIELMO, C.G.; WILLIAMS, T.D.; ZWINGELSTEIN, G.; BRICHON, G.; WEBER, J-M.: Functional Implications of Fatty Acid Composition of Plasma and Muscle Lipids in Migrant Birds We report seasonal changes in concentrations and fatty acid (FA) compositions of plasma non-esterified FA, neutral lipids (NL) and phospholipids (PL), and the FA composition of flight muscle PL in western […]

SHAFER, T.H.; RAFFERTY, M.C.; LEM, S.; MONTOYA, L.M.; DREHS, C.M: Expression of genes potentially important for osmoregulation in blue crab (Callinectes sapidus) embryos and larvae Blue crab embryos are exposed to increasingly salinity as the ovigerous females carrying them migrate to the mouths of estuaries in southeastern NC. Upon hatching, the zoea are planktonic in […]

BURNS, A. C.; ARCHER, J.; SLUSHER, C.; SLUSHER, L.; CASOTTI, G.: Expression and Localization of Aquaporins in the Lower Intestinal Tract of Birds Aquaporins (AQP�s) are membrane integral proteins involved in the passage of water across cell membranes in animals, plants and bacteria. We examined the lower intestinal tract of house sparrows for the presence […]

LEE, S.E.: Examining the evolution of gene sequence and function: The Distal-less (Dlx ) homeodomain ?family?. The homeodomain-containing gene Distal-less (Dll ) is a transcription factor known to be important in proximo-distal axes and nervous system patterning in Drosophila. Dll gene sequence orthologues have been identified from several invertebrates including members of the phyla Cnidaria, […]

FEDER, M.E.: Evolutionary and ecological functional genomics: jumpstarting a new community Describing genomes, their variation, and their change through time is only the first step in rigorous understanding of evolution. Subsequent steps must include elucidating the functional significance of genomic variation in ecological context (i.e., “phenomics”), involving collaboration with functional biologists (e.g., physiologists, biochemists, developmental […]

SNELL, EA*; HOLLAND, PWH: Evolution of the non-integrin 67kDa Laminin Receptor: insights from choanoflagellates The change from unicellularity to multicellularity is one of the most fundamentally important steps in animal evolution. Currently there is a paucity of information indicating the genetic and developmental changes that occurred during this jump from protists to metazoans. One particularly […]

ZIGLER, K.S.*; LESSIOS, H.A.: Evolution of bindin in the pantropical sea urchin genus Tripneustes The sperm protein bindin mediates sperm-egg attachment and sperm-egg membrane fusion in sea urchins. Changes in this locus can thus cause gametic incompatibility and convert populations into different species. We examined bindin evolution in the genus Tripneustes. The genus Tripneustes is […]

HOLLIDAY, J.A.: Evolution of Hypercarnivory: The effect of specialization on character change In mammalian carnivores, hypercarnivory is characterized by specific morphological changes including elongation of the carnassial blade and reduction of the post-carnassial dentition. The most extreme adaptations to the condition are seen in felids and nimravids, but hypercarnivory has also evolved in mustelids, viverrids, […]

TERWILLIGER, N*; RYAN, M; JAENICKE, E; DECKER, H: Evolution of Copper-Oxygen Proteins: Hemocyanins Function as Phenoloxidases Hemocyanins from arthropods are well known as oxygen transport molecules, but under some conditions they can function as phenoloxidases. Phenoloxidases and tyrosinases (EC 1.14.18.1) are found in fungi and plants as well as animals, and they are involved in […]

IANOWSKI, J.P.*; O’DONNELL, M.J.: Evaluation of Na+:K+:2Cl– cotransport across the basolateral membrane in Malpighian (renal) tubule cells of Rhodnius prolixus. Malpighian tubules (MTs) of Rhodnius prolixus are among the most rapid fluid-transporting epithelia known. The current model of serotonin-stimulated fluid secretion in Rhodnius MT cells proposes that transport of Na+, K+, Cl– and osmotically-obliged water […]
