A Comparison Of Sockeye Salmon (Oncorhynchus Nerka) In Two Climate Regimes In The North Pacific Ocean Using Stable Carbon And Nitrogren Isotope Ratios, Franklin Robert Satterfield

Marine Biology

This study explores how the climate shift in the late 1970's impacted sockeye salmon feeding. Stable isotope ratios (¹³C and ¹⁵N) of recent muscle and scale tissues from five mature salmon species are highly correlated (R²=0.96 and 0.91, respectively), validating the use of archived scales for retrospective analysis. These data suggest a trophic separation by species with chinook occupying the highest level, followed by coho with some degree of overlap among sockeye, pink and chum at the lowest level. Archived scales from four different sockeye stocks from Kodiak Island and Southeast region were analyzed over the last 34 years to …

Experimental And Economic Evaluation Of Gtl Fluid Flow Properties And Effect On Taps, Hariharan Ramakrishnan

Engineering

In this study, procedures are outlined to recondition and sample crude oil from high-pressure Welker cylinders. Standard laboratory procedures are developed to determine viscosity and density properties of crude oil, GTL and their mixtures. The steps needed to ensure Quality Assurance and Project Plan (QAPjp) is given in detail. A calibration macro is written to automate viscometer calibration calculations. A preliminary economic model is developed to evaluate GTL transportation options. Viscosity and density are measured for various samples at different temperatures. The reproducibility of the results is found to be within 5%. Batching is more preferable then blending for the …

Spatial-Temporal Variation In Reproduction And Site Fidelity Of Spectacled Eiders On The Yukon-Kuskowkim Delta, Alaska, Christine Leigh Moran

Biological Sciences

In response to recent decline, we compared migration and nesting chronology, nest success, and clutch size of spectacled eiders nesting at Kigigak Island with those nesting on Kashunuk River to better understand regulation of the spectacled eider breeding population on Y-K Delta. We also examined and compared subpopulation relationships between nest site fidelity and breeding performance. We examined the relationship between female age and distance moved between consecutive year nest sites. Clutch sizes were comparable between the two sites and declined seasonally with older females laying earlier and larger clutches. Mayfield nest success was higher due to lower predation and …

Habitat Selection By Calving Caribou Of The Central Arctic Herd, 1980-95, Scott Adrian Wolfe

Biological Sciences

Habitat selection by calving caribou (Rangifer tarandus granti) of the Central Arctic Herd, Alaska, was assessed in relation to distance from roads, vegetation type, relative plant biomass (NDVI; Normalized Difference Vegetation Index), accumulation of plant biomass during early lactation (NDVIrate), snow cover, and terrain ruggedness. From 183 calving sites of 96 radio collared- females, 1980-95, calving distribution was estimated in reference (no development) and treatment (oilfields present) zones east and west of the Sagavanirktok River, respectively. In the reference zone, caribou regularly selected wet-graminoid vegetation, above-median NDVIrate, and non-rugged terrain; concentrated calving remained in habitats with zonal average NDVI on …

Survival And Brood Rearing Ecology Of Emperor Geese, Joel A. Schmutz

Biological Sciences

Emperor Geese (Chen canagica) breed on the Yukon-Kuskokwim Delta in an area inhabited by three other goose species. Whereas populations of other geese increased since the mid 1980s, Emperor Goose numbers remained low. Because survival and habitat selection by broods of Emeperor Geese had not been studied previously and numbers of predatory Glaucous Gulls (Larus hyperboreus) had recently increased, I studied brood rearing ecology of Emperor Geese during 1993-1996 to assess whether this seasonal period could be limiting population growth. Survival of goslings to 30 days varied among years from 0.32 to 0.70 and was primarily influenced by mortality during …

Systematics Of Beringian Threespine Sticklebacks, John S. Chythlook

Biological Sciences

In Pleistocene Beringia, large-scale glaciations exposed high latitude species to variable environmental conditions that created disjunct populations of terrestrial and marine species. The general nature of the dynamic biogeographic history of Beringia can be assessed by studying genetic patterns across many Beringian organisms. Mitochondrial DNA sequences were used to study the phylogenetic and phylogeographic structure of the threespine stickleback, Gasterosteus aculeatus. A 714 bp fragment of the cytochrome b gene was sequenced from 66 individuals from 17 locations extending from southeast Alaska northwest to coastal Siberia. These data were combined with 36 homologous cyt-b sequences from a previous study to …

Impaired Fast-Spiking, Suppressed Cortical Inhibition, And Increased Susceptibility To Seizures In Mice Lacking Kv3.2 K+ Channel Proteins, David Lau, Eleazar Vega-Saenz De Miera, Diego Contreras, Alan Chow, Richard Paylor, Christopher S. Leonard, Bernardo Rudy

NYMC Faculty Publications

Voltage-gated K(+) channels of the Kv3 subfamily have unusual electrophysiological properties, including activation at very depolarized voltages (positive to -10 mV) and very fast deactivation rates, suggesting special roles in neuronal excitability. In the brain, Kv3 channels are prominently expressed in select neuronal populations, which include fast-spiking (FS) GABAergic interneurons of the neocortex, hippocampus, and caudate, as well as other high-frequency firing neurons. Although evidence points to a key role in high-frequency firing, a definitive understanding of the function of these channels has been hampered by a lack of selective pharmacological tools. We therefore generated mouse lines in which one …

Characterization Of Hydra Type Iv Collagen: Type Iv Collagen Is Essential Is Essential For Head Regeneration And Its Expression Is Up-Regulated Upon Exposure To Glucose: Type Iv Collagen Is Essential For Head Regeneration And Its Expression Is Up-Regulated Upon Exposure To Glucose, Susan J. Fowler, Sheba Jose, Xiaoming Zhang, Rainer Deutzmann, Michael P. Sarras, Raymond P. Boot-Handford

College of Health and Human Services

Hydra vulgaris mesoglea is a primitive basement membrane that also exhibits some features of an interstitial matrix. We have characterized cDNAs that encode the full-length hydra α1(IV) chain. The 5169-base pair transcript encodes a protein of 1723 amino acids, including an interrupted 1455-residue collagenous domain and a 228-residue C-terminal noncollagenous domain. N-terminal sequence analyses of collagen IV peptides suggest the molecule is homotrimeric. Denatured hydra type IV collagen protein occurs as dimers and higher order aggregates held together by nonreducible cross-links. Hydra collagen IV exhibits no functional evidence for the presence of a 7 S domain. Type IV collagen is …

The Demand For Aquacultural Products In Taiwan -- An Inverse Demand System Approach, Fu-Sung Chiang, Jonq-Ying Lee

Journal of Marine Science and Technology–Taiwan

This study compared two inverse demand systems, the Rotterdam inverse demand system and the Laitinen-Theil inverse demand system, to analyze the demand relationships among aquacultural products in Taiwan. Results demonstrate that the Laitinen-Theil’s inverse demand system fits the data better than the Rotterdam inverse demand system. The demand relationships among five groups of aquacultural products, tilapia, milkfish, other aquaculture fish, shrimp, and shellfish were examined. Monthly transaction prices from local fish markets and per capita consumption for the period from July 1990 through December 1995 for these five groups of aquacultural products were used in this study. Results show that …
