ROUSE, M.N.*; FOX, S.F.; HUSAK, J.F.; Oklahoma State University, Stillwater; Oklahoma State University, Stillwater; Oklahoma State University, Stillwater: Does asymmetry relate to components of fitness in Crotaphytus collaris? Random deviation from perfect symmetry in bilateral morphological characters among individuals in a population, known as fluctuating asymmetry, has been used as an indicator of the inability […]

DAW, K.J ; RODNICK, K.J.; Idaho State University: Does Exogenous Glucose Prevent Glycogen Depletion in Ventricle strips of Rainbow Trout Oncorhynchus mykiss? Due to their relative intolerance of carbohydrate, diets for carnivorous fish like rainbow trout consist primarily of proteins and lipids. Carbohydrate is important in cardiac metabolism, however little is known about the relative […]

LUXAMA, J.; CRAWFORD, A.; CARROLL, M.A.; CATAPANE, E.J.; Medgar Evers College, Brooklyn, NY; Medgar Evers College, Brooklyn, NY; Medgar Evers College, Brooklyn, NY; Medgar Evers College, Brooklyn, NY: Distribution of Cadmium and Copper in Tissues of Crassostrea virginica Jamaica Bay (JB), NY contains metals and other pollutants. We showed Crassostrea virginica seed transplanted to JB […]

XIA, Mingjing; FENG, Guolei; PITTMAN, Charles U; WANG, Shiao Y; Univ. Southern Mississippi, Hattiesburg; Univ. Southern Mississippi, Hattiesburg; Mississippi State Univ., Starkville; Univ. Southern Mississippi, Hattiesburg: Differences in gene expression between Gulf killifish exposed to phenanthrene and reduced phehanthrene Polycyclic aromatic hydrocarbons (PAHs) are pollutants of concern because of their widespread occurrence and because some […]

HAMDOUN, Amro; HODIN, Jason; SMITAL, Tvrtko; EPEL, David; Hopkins Marine Station, Stanford University; Univeristy of Washington, Seattle; Rudjer Boskovic Institute, Croatia; Hopkins Marine Station, Stanford University: Developmental Regulation of Multidrug Efflux Transporter Activity in Echinoderm Embryos Here we present a study of multidrug (mdr) efflux transporter activity during embryonic and larval development through metamorphosis in […]

BONIER, F.; MARTIN, P.R.; RAMENOFSKY, M.; WINGFIELD, J.C.; University of Washington; University of Washington; University of Washington; University of Washington: Departure Biology of an Arctic-breeding Passerine In the fall, migratory birds prepare to depart the Arctic for southerly clines to overwinter. Whereas a great deal is known of the preparatory stages for spring (northward) migration, […]

SERRANO-VELEZ, J.L.*; ROSA-MOLINAR, Eduardo; University of Puerto Rico – Rio Piedras; University of Puerto Rico – Rio Piedras: Dendritic arbors of secondary motor neurons show scaled growth during anterior transposition of the Western Mosquitofish, Gambusia affinis affinis sexually dimorphic anal fin: a study of morphometric properties. In the present study, we examined the structural and […]

CONTRERAS, H.*; TALBOT, C.; Calif. State. Univ. San Bernardino: Dehydration Threshold of California and Pacific Tree Frogs, Pseudacris cadaverina and P. regilla Evaporative water loss occurs rapidly across amphibian integument, thus highly terrestrial amphibians, such as the California (Pseudacris cadaverina) and Pacific (P. regilla) Tree Frogs, are susceptible to high degrees of dehydration. To counteract […]

KITAYSKY, A.S.*; SHULTZ, M.T.; BENOWITZ-FREDERICKS, M.Z.; KITAISKAIA, E.V.; IAB & Department of Biology and Wildlife, Univ. of Alaska, Fairbanks: Corticosterone levels link food availability and fitness in seabirds The field endocrinology approach substantially enhances traditional methods used to assess food availability for seabirds. Traditional methods are indirect and have limited implementation on large spatial and […]

BELDEN, L.K.*; WINGFIELD, J.C.; KIESECKER, J.M.; Virginia Polytechnic Institute and State University; University of Washington; Pennsylvania State University: Corticosterone and growth in larval amphibians (Rana sylvatica, Ambystoma jeffersonianum and Scaphiopus holbrooki) In amphibians, corticosterone (the main glucocorticosteroid) has a role in both responses to environmental perturbations and in regulating larval growth and development preceding metamorphosis.
