Recovery Of The Wide-Field Infrared Explorer Spacecraft, David Everett, Thomas Correll, Scott Schick, Kimberly Brown

Small Satellite Conference

The Wide Field Infrared Explorer was developed to perform astronomy using a cryogenically cooled infrared telescope. Shortly after launch, rapid venting of the cryogen, caused by an untimely cover removal, sent the spacecraft into an uncontrollable spin which exceeded 60 revolutions per minute. Over the next week, the WIRE team developed a plan and successfully executed the procedures necessary to de-spin the spacecraft and gain attitude control, but the cryogen for cooling the instrument was depleted. The recovery of the spacecraft enabled a thorough checkout of most of the subsystems, including the validation of several new technologies. Although the primary …

State’S Net Farm Income Levels Tell Quite A Story, Bruce B. Johnson, Jared Burkholder

Cornhusker Economics

Nebraska’s 1999 net farm income levels document what people in the industry already knew – 1999 was not a good year for the agricultural economy. According to the recently released 1999 USDA net farm income statistics, Nebraska’s 1999 aggregate net farm income was estimated at $1.66 billion. This total falls 10 percent below the 1998 figure and nearly 18 percent below the annual average of the 1990’s (Table 1).

Phototrophic Anaerobic Lagoons As Affected By Copper And Zinc In Swine Diets, John E. Gilley, Daniel P. Spare, Richard K. Koelsch, Dennis D. Schulte, Phillip S. Miller, Anne M. Parkhurst

Department of Agricultural and Biological Systems Engineering: Faculty Publications

Odor emissions from anaerobic lagoons containing large populations of phototrophic bacteria are usually minimal. This study was conducted to determine whether copper (123 ppm) and zinc (2,310 ppm) in diets fed to weanling pigs for therapeutic purposes affect phototrophic conditions within lagoons. Column reactors containing 47 L of swine lagoon sludge and supernatant were used to represent lagoons. The reactors were placed in an environmental chamber maintained at 24° C. Copper, zinc, and control manure were added to the reactors at a volatile solids loading rate of 128 g_vs m^–3 da^–1 using a hydraulic retention time of …

Consequences Of Dominance-Mediated Habitat Segregation In American Redstarts During The Nonbreeding Season, Peter P. Marra, Richard T. Holmes

Dartmouth Scholarship

Several species of migratory songbirds exhibit a distinct form of habitat segregation while on their Neotropical wintering grounds in which males and females occupy different habitat types. In the American Redstart (Setophaga ruticilla), that sexual habitat segregation is a result of behavioral dominance of older males. In that study, we examined whether such dominance behavior and the resulting differential habitat segregation has consequences for the condition or survival of excluded individuals. We quantified the physical condition and survival of redstarts (both males and females) occupying two habitat types that differed in the proportion of males and females present …

The Phonology And Morphology Of The Tanacross Athabaskan Language, Gary Holton

Alaska Native Language Center Faculty

This dissertation presents a linguistic description of the phonology and morphology of Tanacross Athabaskan, an endangered language spoken by approximately sixty persons in eastern interior Alaska. There is little extant documentation of Tanacross; hence, this description is based primarily on data gathered from first-hand field work. Tanacross is typical of the Athabaskan family in its typological characteristics. There is a relatively small phonemic inventory, and most of the phonemic contrasts are neutralized outside the stem-syllable onset position. The lexicon is relatively small, consisting of perhaps six thousand distinct morphemes. Noun morphology is relatively straightforward, with few active morphological processes. In …

Potential Muskox Habitat In The National Petroleum Reserve-Alaska: A Gis Analysis, Fiona Susan Danks

Biological Sciences

Muskoxen (Ovibos moschatus), reestablished in northern Alaska in recent decades, have been increasing in number and distribution. However, their selection of habitat within the landscape, historically and presently, remains inadequately documented. This project produced maps of predicted muskox habitat in the National Petroleum Reserve-Alaska (NPR-A), that provide a basis for management of muskoxen and protection of their habitat in relation to proposed oil, gas and mineral exploration. Vegetation analyses showed compositional differences and interactions between vegetation and terrain. Within a geographical information systems (GIS) database, muskox locations, satellite-based vegetation maps and terrain data for the Kuparuk River drainage basin were …

Chemo-Ecological And Evolutionary Aspects Of The Pollinator Reward System In Clusia Grandiflora (Clusiaceae), John Lokvam

Agriculture and Horticulture

The dioecious, neotropical plant species Clusia grandiflora produces two major pools of secondary metabolites, latex and floral resin. Latex serves as a defense against herbivory and floral resin as a pollinator reward. This reward is gathered by bees who use it as a nest construction material. Nuclear magnetic resonance and mass spectral studies show that C. grandiflora latex and resin share two classes of compounds, poly-isoprenylated benzophenones and tocotrienoic acids as major or minor components. The close chemical correspondence between latex and resin indicate that they are evolutionarily related. Though the tocotrienes were not found to have biological activity, benzophenones …

Length-Based Models And Population Analyses For Northern Shrimp Pandalus Borealis Krøyer, Caihong Fu

Fisheries

The lack of basic knowledge on stock dynamics o f northern shrimp Pandalus borealis, a protandric hermaphrodite, has caused difficulty in regulating fishing effort on a scientific basis and in understanding potential causes behind population fluctuations and collapses. Previous length-based population models (LBMs), developed for other species, are undesirable primarily for two reasons: (1) individual cohort dynamics are masked; (2) variations in annual natural mortality (M) are ignored. This research was primarily aimed at developing a more advanced LBM that provides estimates of parameters such as recruitment (R), fishing mortality (F) and especially annual M. Simulation-estimation experiments were conducted to …

At about 22.5 metre from the entrance [a fisherman] activated a mine (most probably a PROM-1) whose explosive blast threw him badly so that his head was found 2 metres from the crater from where the mine detonated, with his legs in the direction of the exit.

Phylogeography And Population Genetics Of Northern Flying Squirrels (Glaucomys Sabrinus) In Southeast Alaska, Allison Lynn Bidlack

Biological Sciences

The Prince of Wales flying squirrel (Glaucomys sabrinus griseifrons), a forest associated species, is endemic to several islands in the Alexander Archipelago of Southeast Alaska. Mitochondrial and nuclear markers were examined to assess the genetic uniqueness of this subspecies and its geographic extent and to investigate gene flow among island and mainland populations of flying squirrels. Data from both sets of markers are congruent, and agree with the subspecific designation. The data also indicate that the Prince of Wales subspecies is isolated from other populations in Southeast Alaska, but that there may be gene flow among islands on which it …

Neuroendocrine Control Of Song In The Dark-Eyed Junco (Junco Hyemalis), Stephanie Marie Dloniak

Biological Sciences

This dissertation includes three discrete projects addressing various aspects of the neuroendocrine control of song in the Dark-eyed Junco (Junco hyemalis), a migratory songbird. Specifically, the roles of testosterone, photoperiodic condition, opioids, and age were investigated with respect to song production and neural plasticity in the regions of the brain that control song (vocal control regions, VCRs)." The author "found that, in males photoperiodic condition and testosterone interact to regulate seasonal VCR volume plasticity, whereas testosterone alone controls song production. The opioid system is probably not involved in VCR plasticity or song production, but is indicated to play a role …

Molecular Evolution Of Martens (Genus Martes), Karen Denise Stone

Biological Sciences

Molecular studies provide the opportunity to re-evaluate and further investigate hypotheses such as those related to phylogenetic relationships, inter- and intra-continental colonizations, population differentiation, and the dynamics of hybrid zones. Three sets of molecular markers, nuclear and mitochondrial, were used to examine phylogenetic relationships among species within a holarctically distributed genus (Martes), and intraspecific diversification and population differentiation within American marten (Martes americana). In American marten, two morphological groups ('americana' and 'caurina') have been recognized, though the level of distinctiveness between them has been debated. My data supported the fossil record's indication that early radiations gave rise to two subgenera …

Response Of Northern Red-Backed Vole (Clethrionomys Rutilus) Populations To A Major Spruce Beetle Infestation In The Copper River Basin, Alaska, Thomas Mcdonough

Biological Sciences

A spruce bark beetle (Dendroctonus rufipennis) epidemic in the Copper Basin of Alaska beginning in the late 1980's has infested over 200,000 ha of white spruce forests in the region. The impact of spruce beetle-induced habitat changes on the northern red-backed vole (Clethrionomys rutilus) was investigated using mark/recapture techniques for 2 field seasons. Vole abundance and recruitment was significantly greater on low versus heavily infested sites but a large vole survival response was lacking. Vole food resources and protective vegetative cover did not vary substantially in areas with different levels of spruce mortality. Male movement distances were influenced by sex …

Aspects Of Genetic And Morphological Variation In Selected New World Land Birds, Jacqueline Joyce Weicker

Biological Sciences

The objective of this thesis is to examine variation in certain New World land birds, focusing on morphological difference at the intraspecific level and genetic differences at the intra- and interspecific levels. First, I investigate sexual dimorphism in the Wilson's Warbler (Wilsonia pusilla), a Nearctic-Neotropic migrant parulid. Using museum specimens, I quantify the degree of dimorphism and devise a method to distinguish the sexes using morphological measurements. Second, I outline a new method of approximating Weir and Cockerham's 0 (1984, 1993), an unbiased estimator of genetic population structure. The method uses commonly published parameters and obviates the need to recode …
