Vertebral Pathologies In Skeletons Of Alaskan Eskimos From Golovin Bay And Nunivak Island, Scott Stephen Legge Apr 2002

Vertebral Pathologies In Skeletons Of Alaskan Eskimos From Golovin Bay And Nunivak Island, Scott Stephen Legge

Anthropology

The primary objectives of this dissertation are to analyze vertebral pathologies by comparing two Native Alaskan skeletal collections, and assessing these results in terms of the patterning of genetically controlled versus activity related lesions. Skeletal collections housed at the Smithsonian Institution were requested for repatriation by the residents of Golovin Bay and Nunivak Island in 1993 and 1994, respectively. Prior to reburial, the remains were analyzed utilizing the Smithsonian Protocol of Skeletal Analysis (Urcid and Byrd, 1995) at the University of Alaska Fairbanks. Vertebral anomalies and pathologies observed in this study include spondylolysis, spina bifida occulta, Schmorl's nodes, osteoarthritis, transitional …

Phenanthrene Adsorption And Desorption By Melanoidins And Marine Sediment Humic Acids, John Andrew Terschak Apr 2002

Phenanthrene Adsorption And Desorption By Melanoidins And Marine Sediment Humic Acids, John Andrew Terschak

Oceanography

Sediments are major reservoirs of persistent petroleum contamination in marine environments. Petroleum hydrocarbons associate with the sediment organic matter, of which humic acids are an important constituent. This study examined the role that humic acid and its structure plays in the kinetics and mechanisms of polycyclic aromatic hydrocarbon (PAH) interactions with sediments. Natural humic acids, with a wide range of properties, were isolated from Alaska coastal marine sediments. Melanoidins were synthesized and used as humic acid analogs. The humic acids were characterized by elemental and isotopic analyses, Fourier transform infrared spectroscopy, and cross-polarized magic angle spinning 13C nuclear magnetic resonance …

Molecular Mechanisms Of Metabolic Control In The Arctic Ground Squirrel, Jamie Louis Barger Apr 2002

Molecular Mechanisms Of Metabolic Control In The Arctic Ground Squirrel, Jamie Louis Barger

Theses (Unassigned)

The annual cycle of the arctic ground squirrel (Spermophilus parryii) is characterized by periods of intense energy deposition and utilization, and therefore this species an attractive model for investigating the molecular mechanisms of metabolic control in mammals. In late summer, animals become hyperphagic and undergo intense fattening prior to hibernation. Leptin, a hormone produced by white adipose tissue, reverses obesity in rodent genetic models, but the effects of leptin on outbred rodent strains and wild species is modest. Similarly, administration of mouse recombinant leptin did not affect food intake or adiposity during prehibernation fattening in arctic ground squirrels. These results …

Constructed Wetlands For Wastewater Treatment In The Subarctic, David Charles Maddux Apr 2002

Constructed Wetlands For Wastewater Treatment In The Subarctic, David Charles Maddux

Theses (Unassigned)

This research had two basic objectives: to assess the capability of macrophytes indigenous to the subarctic in removal of heavy metals from wastewater and to determine the feasibility of using constructed wetlands for sewage wastewater treatment in a subarctic environment with a focus on rural application. The research consisted of two parts: a greenhouse study in which indigenous macrophytes were subjected to heavy metal pollutants similar to those found in roadway runoff and a constructed wetland built to treat sewage wastewater. Five species of plants were tested in both projects: Arctophila fulva, Carex rhynchophysa, Menyanthes trifoliate, Scirpus validus and Typha …

A Comparative Analysis Of Mhc Genetic Diversity At The Class Ii Loci In Some Arctic Mammalian Species, Zhengyu Wei Apr 2002

A Comparative Analysis Of Mhc Genetic Diversity At The Class Ii Loci In Some Arctic Mammalian Species, Zhengyu Wei

Theses (Unassigned)

The genetic diversity at the Major Histocompatibility Complex (MHC) class II loci in some arctic mammalian species, musk ox, moose, caribou, and bears, have been characterized. The general objective of this study was to broaden the knowledge of the MHC polymorphism, selection, evolution and function in natural populations of arctic mammals. Allelic variation was assessed by analysis of MHC class II DR and DQ loci at exon 2 region. Sequences were amplified via the polymerase chain reaction (PCR), followed by either DNA sequencing after cloning of the PCR products or single-stranded conformation polymorphism (SSCP) analysis and sequencing. Monomorphism was observed …

Tracing Amino Acid Metabolism Of Harbor Seals (Phoca Vitulina) Using Stable Isotope Techniques, Liying Zhao Apr 2002

Tracing Amino Acid Metabolism Of Harbor Seals (Phoca Vitulina) Using Stable Isotope Techniques, Liying Zhao

Marine Biology

Compound specific isotope techniques were used to trace amino acid metabolism in captive harbor seals (Phoca vitulina) through a two-year controlled feeding trial with either Pacific herring (Clupea pallasi ) or walleye pollock (Theragra chalcogramma). Techniques were developed for measuring carbon and nitrogen isotope ratios of individual amino acids. Carbon and nitrogen trophic enrichments in serum of captive harbor seals varied with the two fish diets, which might have resulted from the changes in metabolic pathway due to the differing dietary protein intake between herring and pollock. Data on serum free amino acid compositions also showed, from a different perspective, …

Carbon And Nitrogen Flows In Zero-Water Exchange Shrimp Culture: Inferences Using Stable Isotope Tracers, Michelle A. Epp Apr 2002

Carbon And Nitrogen Flows In Zero-Water Exchange Shrimp Culture: Inferences Using Stable Isotope Tracers, Michelle A. Epp

Marine Biology

Nutrient and energy flow in cultures of Pacific White Shrimp, Litopenaeus vannamei, were examined in zero-water exchange, 1200--1300 L mesocosms at the Oceanic Institute (OI), Waimanalo, Hawaii. A technique was developed for monitoring shrimp use of formulated feeds through the addition of stable isotopically labeled nutrients to the feed ingredients. Crystalline amino acid compounds were ineffective as labels due to their rapid dissolution in the tank water with feed pellet break-up. Labels which were 'packaged' as algal cells prior to addition to the feed pellets were more effectively incorporated into shrimp tissues than crystalline label (approximately 27% versus 8% for …

Sponges Dominant In The Alaska Intertidal: Biology, Ecology, And Genetic Diversity, Ann Lynette Knowlton Apr 2002

Sponges Dominant In The Alaska Intertidal: Biology, Ecology, And Genetic Diversity, Ann Lynette Knowlton

Marine Biology

The role of the sponge, Halichondria panicea, in a Kachemak Bay, Alaska, intertidal community was investigated through field and laboratory experiments. The relationship between H. panicea and co-occurring macroalgae was studied and results indicate that removing macroalgae had no effect on sponge abundance. A laboratory feeding trial investigating H. panicea and its primary predator Archidoris montereyensis showed that nudibranchs consuming symbiotic sponge had higher feeding and egg production rates than individuals eating aposymbiotic sponge. In a simulated predation event, initial sponge growth rates into experimental feeding scars were high, indicating a response mechanism to tissue damage. A naturally occurring high …

Oceans, Watersheds And Humans: Facts, Myths And Realities, Henry Huntington, Steve Colt Apr 2002

Oceans, Watersheds And Humans: Facts, Myths And Realities, Henry Huntington, Steve Colt

ISER Reports

Alaskans expect a great deal from their oceans and watersheds. Commercial fishing, sport fishing, subsistence hunting, recreation, offshore oil and gas development, transportation, and tourism are among the many ways the oceans, coast, watersheds, and their resources are used. These activities, however, can strain or break the capacity of the ecosystem to sustain them and they are not always compatible. Conflicts and controversies between different user groups are increasingly common. The role of societal forces in shaping the human-aquatic relationship is often under-appreciated, but can be critical. Protecting the health of Alaska’s oceans and watersheds requires managing the interactions between …

Phylogeography Of Moose (Alces Alces): Genetic Signatures Of Population History, Kris Joseph Hundertmark Apr 2002

Phylogeography Of Moose (Alces Alces): Genetic Signatures Of Population History, Kris Joseph Hundertmark

Biological Sciences

Through analysis of mitochondrial DNA (mtDNA) sequences, I examined phylogeographic relationships among moose (Alces alces) from Europe, Asia, and North America and inferred historic population trends explaining present-day structure of genetic variance. Diversity of nucleotide composition in cytochrome b was low worldwide, with no variation detected among North American moose. The North American lineage was more closely related to European than to Asian lineages, indicating a recent colonization of North America and refuting the theory of eastern and western races of moose. An analysis of the control region provided greater resolution, which revealed similar yet more detailed patterns, including detectable …

Phylogeography And Population Genetic Structure Of Beringian Landbirds, Christin Leigh Pruett Apr 2002

Phylogeography And Population Genetic Structure Of Beringian Landbirds, Christin Leigh Pruett

Biological Sciences

Molecular genetic approaches can be used to evaluate the historic and current relationships among populations. Mitochondrial DNA sequences and nuclear microsatellite loci were used to examine questions in avian community ecology, biogeography, and population genetics, including: (1) how have simple, high latitude bird communities been historically assembled; (2) how have past climate changes affected a species that has its entire distribution in an area that has experienced many glacial cycles; and (3) what are the genetic effects of sequential peripheral isolation in a natural vertebrate system? Landbird communities in the Aleutian Islands are simple and replicated, having only eight members. …

The Role Of Copepods In The Distribution Of Hydrocarbons: An Experimental Approach, Switgard Duesterloh Apr 2002

The Role Of Copepods In The Distribution Of Hydrocarbons: An Experimental Approach, Switgard Duesterloh

Fisheries

Copepods may provide a significant pathway for the concentration and transfer of polyaromatic compounds (PAC) to higher trophic level consumers. PAC dissolved from weathered crude oil are more persistent in the environment and have much higher toxicity than the lighter, more volatile fractions of crude oil. Because of their polarity, PAC tend to accumulate in bio-lipids. Subarctic copepod species can contain up to 80% of their body dry weight in lipids and have a high surface area to volume ratio. Thus, PAC accumulation is rapid and bioaccumulation factors are in the order of 500--8000, depending upon species and lipid content. …

Variability Of Pink Salmon Family Size Has Implications For Conservation And Management Models, Harold Joseph Geiger Apr 2002

Variability Of Pink Salmon Family Size Has Implications For Conservation And Management Models, Harold Joseph Geiger

Fisheries

In several populations of pink salmon, the short-term dynamics population size was related to both the mean and variance of individual family sizes, because not all families were equally productive. In the marine lifestage, population increases came disproportionately from the most productive families, especially in populations with the highest average marine survival. Moreover, the trait of marine survival itself had a statistically detectable genetic component. This implies that the most favored phenotypes change from generation to generation, and that the marine environment is unpredictable and changing. These results, together with laboratory studies of freshwater survival and measurements of wild pink …
