Phylogenetic Systematics Of The Primate Genus Aotus Based On Hyoid Morphology, Melissa S. Immel '97

Honors Projects

Dissection of a specimen of the South American primate genus Aotus was performed, focusing on the morphology of the hyoid apparatus and surrounding musculature within the hyoid region (the ventral side of the throat). Data collected from this dissection, along with data from published descriptions of primate genera from both primate suborders Haplorhini and Strepsirhini, were analyzed using the computer software program PAUP (Phylogenetic Analysis Using Parsimony). This analysis generated four equally probable phylogenetic trees (cladograms) depicting possible phylogenetic relationships of Aotus to other primates. While the cladograms differ in minor detail, they all show that Aotus appears to be …

Facts: Appellant requested to adopt a young man of 26 years, whom he had raised since infancy, after marrying the young man's biological mother. The potential adoptee, as well as the Israel Children Society, supported the appellant's request. The district court, however, denied the adoption order. The district court held that the requirements of section 25(1) of the Children Adoption Law, which allowed for the adoption of adults under special circumstances, were not fulfilled. The district court also held that the requirements of sections 8(a) and 13 of the law, which required the consent of the biological parents to adoption …

Production Of Vascular Aquatic Plants In Wetlands Of Alaska: A Comparative Study, Amy Sophia Larsen

Biological Sciences

I examined the effects of climate and hydrology on aboveground biomass of macrophytes in wetlands across Alaska by investigating the effects of latitude, July mean air temperature, lake type (open, periodically inundated, and closed), hydrology, and water and sediment chemistry on emergent and submersed vascular plant biomass to determine environmental variables that influenced wetland plant growth. I sampled aboveground biomass of macrophytes in four wetland complexes within Alaska: Kenai and Tetlin National Wildlife Refuges, Minto Flats State Game Refuge, and the Arctic Coastal Plain near Prudhoe Bay, Alaska. In addition to peak aboveground biomass, I also collected water and sediment …

Regulation Of Methyl Farnesoate Production By The Lobster Mandibular Organ In Vitro, Amy Shaub '97

Honors Projects

Methyl farnesoate (MF) is a crustacean compound that is structurally similar to juvenile hormone, a substance that regulates insect growth and reproduction. This similarity has led to the suggestion that MF may have juvenile hormone-like effects in crustaceans. If this is so, regulation of MF levels might be an important mechanism in the control of crustacean molting and reproduction. The understanding of, and ability to manipulate, the regulation of MF production could be a powerful tool in the aquaculture of economically Important crustaceans.

In the lobster Homarus americanus, MF synthesis occurs in the mandibular organ (MO). In vivo studies have …

Structure And Growth Of Pacific Halibut Otoliths: Identifying Spatial And Temporal Variation, Peter Thomas Hagen

Fisheries

Otoliths are polycrystals of calcium carbonate and protein that grow through the process of biomineralization within the otic capsule of teleost fish. Otoliths of Pacific halibut (Hippoglossus stenolepis) are routinely collected to provide age information, but other information has not been examined in detail. The purpose of this study was to investigate whether otolith structural patterns reveal information about otolith growth, and by inference, about fish growth and habitat during its early life. Variation in the increment widths of the first five annuli of adult halibut otoliths over a 26 year period were partitioned in two ways: the year the …

Assessment Of The Benthic Environment Following Offshore Placer Gold Mining In Norton Sound, Northeastern Bering Sea, Stephen Carl Jewett

Fisheries

The effects of placer gold mining on the benthic environment of Norton Sound in the northeastern Bering Sea were assessed. Research focused on red king crab Paralithodes camtschaticus, a species with commercial and subsistence importance in the Sound and seasonal occurrence in the mining area. The study addressed mining effects on: (1) benthic macroinvertebrates, many serving as food for this crab, (2) crab relative abundance, distribution, and food, and (3) heavy metal concentrations in crabs. Mining on variable substrates in $<$20 m water depths occurred between 1986-90 during ice-free months when crabs were further offshore. Sampling nearly a year subsequent to mining revealed moderate substrate alteration. Benthic community parameters and abundance of numerically predominant families (e.g., owenid, spionid, and capitellid polychaetes and echinarachniid sand dollars) were reduced in mined areas. Many reduced taxa are known crab prey. Although young individuals of opportunistic taxa predominated, taxa were generally smaller at mined areas. Multi-year surveys of a once-mined area showed continued smoothing of bottom relief. Ordination of taxon abundance from mined (1 yr after mining), recolonizing (2-7 yrs after mining), and unmined stations reflected decreasing station disturbance. At least four years were required for benthos to recover from mining. Mining had a negligible effect on crabs. Crab catches, size, sex, and most prey groups in stomachs were similar between mined and unmined areas. Concentrations of eight heavy metals in muscle and hepatopancreas tissues were generally not different in mined areas. Furthermore, these metals were not different in sediments upcurrent and downcurrent of mining. Concentrations of most metals in tissues showed no temporal trend. Elemental concentrations in muscle tissues were below or within the range of concentrations in red king crabs from other North Pacific locations. Most metals from Norton Sound crabs were well below federal guidance levels for human consumption. Effects from mining were apparent for benthic macrofauna with virtually no effects observed for king crabs. Absence of any demonstrable effects of mining on this crab is primarily a result of the high natural dynamics of the Sound and opportunistic feeding behavior and high mobility of the crab.

Snow And Ice Thickness Distributions In The South Polar Pacific Ocean, Ute Adolphs

Theses (Unassigned)

Two sets of snow and ice thickness data of antarctic sea ice are presented in this study: drilling profiles on individual sea ice floes and spatially more extensive shipboard observations are investigated in order to reveal spatial and temporal characteristics of sea ice. The data were acquired between 1993 and 1995 in the Ross and the Amundsen/Bellinghausen Seas, two different regions of the south polar Pacific Ocean. Sea ice characteristics as well as their spatial distribution and temporal evolution are derived from the data sets. Strong regional trends are observed in ice thickness distributions of the drilling data. A spatial …

Thermally Enhanced Bioventing Of Petroleum Hydrocarbons In Cold Regions, Dennis M. Filler

Theses (Unassigned)

Petroleum-based contamination of the environment has and will likely continue to be a problem as long as oil and natural gas supply much of the world energy demands. In cold regions, where vast quantities of these fuels are extracted and used, climate and frozen soils limit remedial efforts to a few technologies. Bioventing has shown promise as a viable method for the remediation of spilled petroleum-based fuels in cold regions. An in situ study of bioventing with soil warming was conducted at a Fairbanks, Alaska site. The main purpose of this research effort was to compare the effectiveness of thermal …

Analysis And Comparison Of Cyanide Detoxification Methods From Spent Heaps, Edwin Bane Kroeger

Theses (Unassigned)

This work entailed the testing of cyanide degradation of microorganisms isolated by the U.S. Bureau of Mine's Salt Lake Research Center (SLRC) and native strains isolated from an Alaskan mine, development of conceptual designs for in situ biological detoxification of leached heaps, and comparison of common in situ and ex situ heap detoxification processes using a cost comparison, sensitivity analysis, and Monte Carlo simulation. Microorganisms from an Alaskan mine site and SLRC were tested for cyanide degradation. Testing of samples from the Ryan Lode site indicated that several bacterial colonies could tolerate cyanide, but no degradation was found. Once degradation …

Microbial Ecology And Long-Term Persistence Of Crude Oil In A Taiga Spruce Forest, Jon Eric Lindstrom

Theses (Unassigned)

The microbial ecology of a 1976 experimental crude oil spill in an Alaskan taiga black spruce forest was investigated in this study. Substantial oil residue remained in the soil, and several microbial parameters showed evidence of long-term oiling effects. Overall, the data suggest that the surviving community in the oiled plot has shifted toward using oil C for growth. Numbers of hydrocarbon degrading microbes, and specific hydrocarbon mineralization potentials, were significantly elevated in the oiled (OIL) plot compared to an adjacent oil-free, reference (REF) plot. Glutamate mineralization potentials and soil C mineralization, on the other hand, were not different between …

Proximate And Ultimate Control Of Reproductive Effort In Northern Shovelers (Anas Clypeata) Nesting At Minto Flats, Alaska, Margaret Christine Maccluskie

Theses (Unassigned)

The purpose of this study was to examine factors that influence reproductive effort of female Northern Shovelers (Anas clypeata) nesting at Minto Flats, AK during summer 1991-1993. I investigated the importance of endogenous nutrient reserves to females during egg production and examined changes in organ weights and intestine lengths through the reproductive cycle. Changes in organ weights and intestine length were similar to those of shovelers nesting in Manitoba. Females used neither somatic lipid reserves, protein reserves, nor mineral reserves to produce eggs. Individual variation in somatic lipid reserves was explained by body size and nest initiation date, while variation …

Natural Disturbance At The Site And Landscape Levels In Temperate Rainforests Of Southeast Alaska, Robert A. Ott

Theses (Unassigned)

Wind disturbance in forests of southeast Alaska is poorly understood. Dynamics of canopy gaps, formed primarily by wind, were investigated in the western hemlock (Tsuga heterophylla)/blueberry (Vaccinium spp.)/shield fern (Dryopteris austriaca) plant association in northern southeast Alaska; twenty gaps were sampled at each of 3 sites. Gaps comprised about 9% of the forest area. The majority of gaps were $<$50 m$\sp2$ in area, had a diameter-to-height (D/H) $<$0.50, were created from the death of 1 or 2 gapmakers, and had experienced gap expansion. Emulating the small-scale natural disturbance regime would be best achieved if single tree selection and small group selection cuts were administered within a stand. Diffuse light levels were greatest and most variable at both the shrub and herb layers in canopy gaps, and lowest and least variable under closed canopy forest. Shrub layer light levels were positively associated with mean and median canopy gap areas. Herb layer light levels, however, were determined by the amount of light interception at the shrub layer and not by canopy gap size. Most species were robust in terms of their light requirements compared to the range of light conditions present in the understory. Sorenson Index values indicated that gaps and closed canopy forest generally were very similar in species composition. Seedling heights suggest that western hemlock and Sitka spruce seedlings benefit from the presence of canopy gaps. However, the ability of Sitka spruce to maintain itself through gap-phase replacement is limited. Techniques are needed that allow forest managers to interpret wind patterns in remote locations, at both site- and landscape-levels, and across complex topography. I demonstrated the use of circular data analysis of treefall directions as a technique to investigate wind flows at the site-level. I also demonstrated the feasibility of mapping wind flows across a large landscape of complex terrain in southeast Alaska using flagged trees, treefall directions of large-scale natural blowdowns, and treefall directions of blowdowns associated with clearcuts.

A Nested Watershed Study In The Kuparuk River Basin, Arctic Alaska: Streamflow, Scaling, And Drainage Basin Structure, James Patrick Mcnamara

Theses (Unassigned)

The central hypothesis of this dissertation is that permafrost influences the form, function, and scaling of hydrologic and geomorphologic characteristics in the Kuparuk River basin in Northern Alaska. This problem was addressed using three approaches: field hydrologic studies, statistical scaling studies, and geomorphology studies using digital elevation models. Permafrost and snow exert significant controls on hydrologic processes in the Kuparuk River basin. Storm hydrographs show fast responses, long time lags, extended recessions, and high runoff/precipitation ratios. These features arise from the diminished storage capacity caused by permafrost. Summer storm flow compositions in the are dominated by old water, as is …
