Potential Components Of Time Personality: A Literature Review, Jane Ackerson Feb 2004

Potential Components Of Time Personality: A Literature Review, Jane Ackerson

Honors Theses

What is time? The simple yet puzzling question has been posed on numerous occasions generating various responses. Time can be described as quantifiable, structured, even having monetary value. Time can be viewed in a subjective or objective manner and can be influenced by internal and external factors. Time can create pressure, anxiety, or boredom. Time is what we perceive it to be. This perception is a potentially vital component involved in the makeup of time personality. Theoretically, time personality is shaped by many factors affecting the relationship an individual has with time. The objectives of the research were to identify …

Response Of Tree Ring Holocellulose Δ13C To Moisture Availability In Populus Fremontii At Perennial And Intermittent Stream Reaches, Daniel L. Potts, David G. Williams Feb 2004

Response Of Tree Ring Holocellulose Δ13C To Moisture Availability In Populus Fremontii At Perennial And Intermittent Stream Reaches, Daniel L. Potts, David G. Williams

Western North American Naturalist

We measured δ13C of tree ring holocellulose to assess intra- and interannual variation in integrated leaf gas exchange responses of Frémont cottonwood (Populus fremontii) to monsoonal moisture inputs in southeastern Arizona. We predicted that δ13C of trees growing along drought-susceptible intermittent reaches of this semiarid river system would be more responsive to monsoonal moisture inputs than trees found along perennial reaches, where groundwater is consistently available. We sampled stem xylem cores from 7 trees, each at an intermittent and perennial reach of the San Pedro River near Tombstone, Arizona. We identified and subdivided individual …

Fate And Characteristics Of Picea Damaged By Elatobium Abietinum (Walker) (Homoptera: Aphididae) In The White Mountains Of Arizona, Ann M. Lynch Feb 2004

Fate And Characteristics Of Picea Damaged By Elatobium Abietinum (Walker) (Homoptera: Aphididae) In The White Mountains Of Arizona, Ann M. Lynch

Western North American Naturalist

Spruce aphid, Elatobium abietinum (Walker), is a new invasive pest in high-elevation forests of southwestern USA. Plots in the White Mountains of Arizona were evaluated over several years to assess the extent and severity of damage in high-elevation forests and to identify tree and site characteristics associated with defoliation and mortality. Large areas were defoliated in each of 4 recent outbreaks. Impact from a single defoliation episode included an overall mortality of 10.3% to Picea engelmannii Parry, 24%–41% in severely defoliated trees. Defoliation severity was much greater on P. engelmannii than on P. pungens Engelm. and was more severe in …

Conservation, Status, And Life History Of The Endangered White River Spinedace, Lepidomeda Albivallis (Cyprinidae), G. Gary Scoppettone, James E. Harvey, James Heinrich Feb 2004

Conservation, Status, And Life History Of The Endangered White River Spinedace, Lepidomeda Albivallis (Cyprinidae), G. Gary Scoppettone, James E. Harvey, James Heinrich

Western North American Naturalist

Lepidomeda albivallis (White River spinedace), a fish species endemic to the White River, Nevada, appeared headed toward extinction. In 1991 only 1 population remained, and it comprised fewer than 50 individuals in a 70-m stream reach. We monitored population recruitment and distribution and studied life history and habitat use from 1993 through 1998. We determined that L. albivallis was not reproducing and was continuing to decline, and as an emergency measure we relocated the population (14 in spring 1995 and 6 in spring 1996) downstream 200 m to a secure habitat that we judged more favorable for reproduction. The relocated …

A Fish Survey Of The White River, Nevada, G. Gary Scoppettone, Peter H. Rissler, Sean Shea

Western North American Naturalist

In spring and summer 1991 and 1992, we surveyed fishes of the White River system, Nye and White Pine Counties, Nevada, to determine the status of natives. There are 5 known native fishes to the White River: Lepidomeda albivallis (White River spinedace), Crenichthys baileyi albivallis (Preston White River springfish), Crenichthys baileyi thermophilus (Moorman White River springfish), Catostomus clarki intermedius (White River desert sucker), and Rhinichthys osculus ssp. (White River speckled dace). All 5 had declined in range. Lepidomeda albivallis had experienced the greatest decline, with less than 50 remaining, and these were restricted to a 70-m stream reach. Rhinichthys osculus …

Coyote (Canis Latrans) Movements Relative To Cattle (Bos Taurus) Carcass Areas, Jan F. Kamler, Warren B. Ballard, Rickey L. Gilliland, Kevin Mote Feb 2004

Coyote (Canis Latrans) Movements Relative To Cattle (Bos Taurus) Carcass Areas, Jan F. Kamler, Warren B. Ballard, Rickey L. Gilliland, Kevin Mote

Western North American Naturalist

Use of 2 cattle carcass areas was determined for radio-collared coyotes (Canis latrans) in northwest Texas from January 1999 to January 2000. When 0–3 dead cattle were located at the carcass areas, resident and transient coyotes visited the carcass areas 4% and 8% of the time, respectively. However, when 30–35 dead cattle were located at 1 carcass area due to a disease epizootic, resident and transient coyotes had increased visitation rates of 19% and 63%, respectively. Resident coyotes traveled as far as 12.2 km from the center of their home ranges, suggesting that carcass areas influenced residents over …

Spawning Ecology Of Finespotted Snake River Cutthroat Trout In Spring Streams Of The Salt River Valley, Wyoming, Michael P. Joyce, Wayne A. Hubert Feb 2004

Spawning Ecology Of Finespotted Snake River Cutthroat Trout In Spring Streams Of The Salt River Valley, Wyoming, Michael P. Joyce, Wayne A. Hubert

Western North American Naturalist

We studied spawning ecology of cutthroat trout (Oncorhynchus clarki) in streams that originate as springs along the Salt River, a Snake River tributary in western Wyoming. We assessed (1) relative numbers of upstream-migrant and resident adults present during the spawning period in spring streams, (2) influence of habitat modification on use of spring streams for spawning, and (3) habitat features used for spawning in spring streams. Four spring streams were studied, 2 with substantial modification to enhance trout habitat and 2 with little or no modification. Modifications consisted primarily of constructing alternating pools and gravel-cobble riffles. Only a …

Habitat Of Three Rare Species Of Small Mammals In Juniper Woodlands Of Southwestern Wyoming, Kevin M. Rompola, Stanley H. Anderson Feb 2004

Habitat Of Three Rare Species Of Small Mammals In Juniper Woodlands Of Southwestern Wyoming, Kevin M. Rompola, Stanley H. Anderson

Western North American Naturalist

Southwestern Wyoming constitutes the northern limit of the ranges of the cliff chipmunk (Tamias dorsalis), pinyon mouse (Peromyscus truei), and canyon mouse (P. crinitus). In addition to trying to determine their presence in the region, we wanted to identify habitat characteristics commonly used by each of these species. We used Sherman live-traps to sample 14 sites representing 2 distinct habitat types in 1998 and 1999: juniper-rocky slopes and juniper cliffs. Seventeen habitat characteristics were measured at capture locations for each species and compared with randomly located points. Best subsets multiple logistic regression was used …

Beavers Indirectly Enhance The Growth Of Russian Olive And Tamarisk Along Eastern Montana Rivers, Peter Lesica, Scott Miles Feb 2004

Beavers Indirectly Enhance The Growth Of Russian Olive And Tamarisk Along Eastern Montana Rivers, Peter Lesica, Scott Miles

Western North American Naturalist

Russian olive and tamarisk are introduced woody plants invading western North American riparian communities. Beavers can play an important role in structuring these communities by removing the dominant cottonwood trees. Our study explored the way in which beavers interact with cottonwood, Russian olive, and tamarisk along 4 rivers on the Great Plains of eastern Montana. We sampled cottonwood stands that supported populations of 1 or both exotic species, recording beaver damage and density in addition to size and age of cottonwood, Russian olive, and tamarisk. In stands where beaver had been present, they felled an average of 80% of cottonwood …

Contribution To The Morphology And Descriptive Biology Of Caurinella Idahoensis (Ephemeroptera: Ephemerellidae), Luke M. Jacobus, W. P. Mccafferty Feb 2004

Contribution To The Morphology And Descriptive Biology Of Caurinella Idahoensis (Ephemeroptera: Ephemerellidae), Luke M. Jacobus, W. P. Mccafferty

Western North American Naturalist

Reared specimens from Bridge Creek, Idaho County, Idaho, provide the bases for the first descriptions of Caurinella idahoensis egg and alate stages and redescription of the larval stage. Larvae are distinguished from other Nearctic Ephemerellinae species by the distinctive posterolateral projections on abdominal segment 9. Male adults have a unique combination of characters associated with their genitalia. Larvae were associated with the colonial bluegreen alga Nostoc parmelioides in a clear, cold headwater stream. Several other Diptera, Ephemeroptera, Plecoptera, and Trichoptera also were found in cohabitation with C. idahoensis. Amorphous detritus appears to be a major component of the diet …

A Putative Hybrid Swarm Within Oönopsis Foliosa (Asteraceae: Astereae), Jonathan F. Hughes, Gregory K. Brown Feb 2004

A Putative Hybrid Swarm Within Oönopsis Foliosa (Asteraceae: Astereae), Jonathan F. Hughes, Gregory K. Brown

Western North American Naturalist

Oönopsis foliosa var. foliosa and var. monocephala are endemic to short-grass steppe of southeastern Colorado and until recently were considered geographically disjunct. The only known qualitative feature separating these 2 varieties is floral head type; var. foliosa has radiate heads, whereas var. monocephala heads are discoid. Sympatry between these varieties is restricted to a small area in which a range of parental types and intermediate head morphologies is observed. We used distribution mapping, morphometric analyses, chromosome cytology, and pollen stainability to characterize the sympatric zone. Morphometrics confirms that the only discrete difference between var. foliosa and var. monocephala is radiate …

Soil Compaction From Human Trampling, Biking, And Off-Road Motor Vehicle Activity In A Blackbrush (Coleogyne Ramosissima) Shrubland, Simon A. Lei Feb 2004

Soil Compaction From Human Trampling, Biking, And Off-Road Motor Vehicle Activity In A Blackbrush (Coleogyne Ramosissima) Shrubland, Simon A. Lei

Western North American Naturalist

Soil compaction from human trampling, biking, and off-road motor vehicle traffic was quantitatively investigated in a blackbrush (Coleogyne ramosissima) shrubland in Kyle Canyon of the Spring Mountains in southern Nevada. A significant difference was detected in soil compaction, bulk density, and percent pore space at a particular frequency of visits in each of 4 disturbance types. On average a single vehicle pass was equivalent to 10 human footprints. Ten and 100 footprints were equivalent to 1 motorcycle pass and 10 vehicle passes, respectively. Soil compaction is a product of increased bulk density and decreased pore space. The degree …

Occurrence And Habitat Use Of Passage Neotropical Migrants In The Sonoran Desert, Paul C. Hardy, David J. Griffin, Amy J. Kuenzi, Michael L. Morrison Feb 2004

Occurrence And Habitat Use Of Passage Neotropical Migrants In The Sonoran Desert, Paul C. Hardy, David J. Griffin, Amy J. Kuenzi, Michael L. Morrison

Western North American Naturalist

Little is known about stopover habitat use by neotropical migratory birds in the deserts of North America. We determined distribution, abundance, and habitat associations of neotropical migrants during spring migration in the Sonoran Desert of southwestern Arizona along large washes that supported xeroriparian scrub vegetation. We detected 91 bird species during surveys, 50 (52%) of which were passage neotropical migrants. Although xeroriparian scrub covered less than 55% of the area surveyed, 97% of all detections of passage migrants were from this vegetation type. By calculating habitat breadth for each species, we classified 87% of passage migrants as xeroriparian specialists. Richness …

Species Diversity And Habitat Of Grassland Passerines During Grazing Of A Prescribe-Burned, Mixed-Grass Prairie, Robert F. Danley, Robert K. Murphy, Elizabeth M. Madden Feb 2004

Species Diversity And Habitat Of Grassland Passerines During Grazing Of A Prescribe-Burned, Mixed-Grass Prairie, Robert F. Danley, Robert K. Murphy, Elizabeth M. Madden

Western North American Naturalist

No published data exist on responses of grassland passerines and their habitat to combined grazing and burning treatments in northern mixed-grass prairie. At Lostwood National Wildlife Refuge (LNWR) in northwestern North Dakota, we monitored breeding bird occurrence, abundance, and habitat during successive annual grazing treatments (1998–2000) on 5 prescribe-burned, mixed-grass prairie management units (range = 50–534 ha, each burned 3–6 times in the previous 10–20 years). All breeding passerine species characteristic of upland, northern mixed-grass prairie were common (>10% occurrence) during at least 1 of 3 years on burned and grazed units, except Chestnut-collared Longspur (Calcarius ornatus), …

Methionine Sulfoxide Reduction In Mammals: Characterization Of Methionine-R-Sulfoxide Reductases, Hwa-Young Kim, Vadim Gladyshev Feb 2004

Methionine Sulfoxide Reduction In Mammals: Characterization Of Methionine-R-Sulfoxide Reductases, Hwa-Young Kim, Vadim Gladyshev

Vadim Gladyshev Publications

Methionine residues in proteins are susceptible to oxidation by reactive oxygen species, but can be repaired via reduction of the resulting methionine sulfoxides by methionine-S-sulfoxide reductase (MsrA) and methionine-R-sulfoxide reductase (MsrB). However, the identity of all methionine sulfoxide reductases involved, their cellular locations and relative contributions to the overall pathway are poorly understood. Here, we describe a methionine-R-sulfoxide reduction system in mammals, in which two MsrB homologues were previously described. We found that human and mouse genomes possess three MsrB genes and characterized their protein products, designated MsrB1, MsrB2, and MsrB3. MsrB1 (Selenoprotein R) was present in the cytosol and …
