ROYAL, TD; KELLEY, KM; California State Univ., Long Beach; California State Univ., Long Beach: Molecular and Physiological Characterization of an Insulin-like Growth Factor-binding Protein in a Chondrichthyean Fish Studies in fishes have demonstrated that insulin-like growth factor-binding proteins (IGFBPs) are differentially regulated by a variety of hormones and under different physiological circumstances. For example, stressful […]

Molecular Cloning of Putative Chemosensory G proteins from a Spionid Polychaete
TSIE, M; RAWSON, P; LINDSAY, S; University of Maine, Orono ME; University of Maine, Orono ME; University of Maine, Orono ME: Molecular Cloning of Putative Chemosensory G proteins from a Spionid Polychaete The spionid polychaete, Dipolydora quadrilobata is a marine worm whose feeding behavior is influenced by binding chemical cues. In most organisms, odorant receptors […]
Molecular Characterization of Hemolymph Storage Proteins in the Lubber Grasshopper
HATHAWAY, M.J.*; LI, S.*; DING, X.*; HATLE, J.D.*; BORST, D.W.; Illinois State Universtiy: Molecular Characterization of Hemolymph Storage Proteins in the Lubber Grasshopper In many insects, storage proteins (SP) provide an amino acid reserve that can be used during metamorphosis and reproduction. In the lubber grasshopper, Romalea microptera, there are three abundant hemolymph proteins (~500kDa, […]
Modulation of Water Permeability in Gills of Geukensia demissa During High-Salinity Adaptation
KAPPER, M.A.; Central Connecticut State University: Modulation of Water Permeability in Gills of Geukensia demissa During High-Salinity Adaptation During the course of adaptation to altered environmental salinities, estuarine molluscs typically swell or shrink according to the osmotic movement of water down its concentration gradient. These volume changes are eventually reversed by the accumulation or elimination […]
Minimal over-wintering temperatures of red-sided garter snakes A possible cue for emergence
LUTTERSCHMIDT, D.I.*; LEMASTER, M.P.; MASON, R.T.; Oregon State Univ., Corvallis; Western Oregon Univ., Monmouth; Oregon State Univ., Corvallis: Minimal over-wintering temperatures of red-sided garter snakes: A possible cue for emergence? Red-sided garter snakes (Thamnophis sirtalis parietalis) in Manitoba, Canada inhabit the northernmost limit of this species� range. Beginning in May, snakes emerge from hibernacula after […]
Male ornament size profiles vigor and size of bill armament in a monogamous colonial seabird
DOUGLAS III, H.D.; KITAYSKY, A.S.; KITAISKAIA, E.V.; Univ. Alaska Fairbanks; Univ. Alaska Fairbanks; Univ. Alaska Fairbanks: Male ornament size profiles vigor and size of bill armament in a monogamous colonial seabird We studied correlates of ornamental traits in the Crested Auklet Aethia cristatella, a colonial seabird of the North Pacific, known for mutual sexual selection. […]
Lower leptin levels in mice selected for high voluntary wheel running
GIRARD*, I; REZENDE, EL; GARLAND, JR., T; Univ.of Wisconsin-Stevens Point; Univ.of Calif., Riverside; Univ.of Calif., Riverside: Lower leptin levels in mice selected for high voluntary wheel running Selective breeding has produced 4 replicate lines of High-Runner (HR) mice that run about 2.7-times more revolutions/day as compared with 4 unselected Control (C) lines. Previous studies have […]
Locomotor behavior of zebrafish with aberrant myomere morphology
PAUL*, J. C.; HALE, M. E. ; Univ. of Chicago; Univ. of Chicago: Locomotor behavior of zebrafish with aberrant myomere morphology Fish generate axial bending through contractions of the myomeres, serially repeated lateral muscles in the trunk and tail. Myomeres have an elaborate three-dimensional shape and fiber organization. In this study, we examine kinematics of […]
Localization of carbonic anhydrase in the crustacean cuticle
HORNE, F. R.; Texas State University: Localization of carbonic anhydrase in the crustacean cuticle An organic matrix of protein and polysaccharides along with minerals is secreted extracellularly by decapod hypodermal cells. These macromolecules are the sites of ion concentration, crystal nucleation, crystal growth, and control of crystal morphology. Crustaceans manufacture and calcify a new shell […]
Linking morphology, locomotor performance, and fitness in lizards
ZANI, P.A.; Univ. of Colorado: Linking morphology, locomotor performance, and fitness in lizards While the link between morphology and performance has been well studied, evidence that functional morphology affects organismal fitness is scarce. I examined the links between morphology, performance, and fitness by measuring the body and limb morphology of 64 hatchling side-blotched lizards, Uta […]
