Planning And Zoning Around Bear Lake, Utah, Patsy Palacios, Chris Luecke, Justin Robinson Jan 2007

Planning And Zoning Around Bear Lake, Utah, Patsy Palacios, Chris Luecke, Justin Robinson

Natural Resources and Environmental Issues

Communities in the Bear River basin are presently encountering various intensities of growth and development due to new residential, commercial, and agricultural development. In general, the development is distributed unevenly throughout the basin with much heavier concentration occurring south of Grace, Idaho and continuing into Garden City. Around the Bear Lake area, development is sprawling outward from the lakeshore and up the sides of the foothills. The west and south shores are primarily privately owned with summer home development, while the east shore is mostly state owned with multiple access points. See figure 4 for development around Bear Lake. The …

History Of Human Impact On Bear Lake, Patsy Palacios, Chris Luecke, Justin Robinson Jan 2007

History Of Human Impact On Bear Lake, Patsy Palacios, Chris Luecke, Justin Robinson

Natural Resources and Environmental Issues

The immediate uses of the water in Bear Lake, local surrounding streams, and the larger Bear River, were primarily for fishing and irrigation. After building a few aspen cabins, the newly settled pioneers began the task of constructing irrigation canals. Within its valley, the Bear River and its tributaries water over 50,000 acres of land in Rich County. The largest irrigation sources are Big Spring and Swan Creek. Settlers in Laketown, Round Valley, and Meadowville continued to construct a network of canals still being used today; these included the Crawford and Thompson Canal, the Beackwith Canal, and the Chapman Canal …

Mineral Activities Within Rich County, Utah, Patsy Palacios, Chris Luecke, Justin Robinson Jan 2007

Mineral Activities Within Rich County, Utah, Patsy Palacios, Chris Luecke, Justin Robinson

Natural Resources and Environmental Issues

The mineral resources of the area include deposits of phosphate, sand, gravel, limestone, quartzite, and oil. Large deposits of phosphate are in the northern and eastern parts of Rich County. U.S. Geological survey showed extensive deposits of rock-phosphate, stretching from the Crawford Mountains in Bear River Valley to Laketown and on through to Paris and Montpelier, and over the pass into Soda Springs (Parson, 1996). These deposits have been partially mined but continuing mining efforts remain highly dependent on the current market price.

Biological Resources Of The Bear Lake Basin, Utah, Patsy Palacios, Chris Luecke, Justin Robinson Jan 2007

Biological Resources Of The Bear Lake Basin, Utah, Patsy Palacios, Chris Luecke, Justin Robinson

Natural Resources and Environmental Issues

The Bear Lake basin has a range of land types that provide habitat for aquatic, riparian, and terrestrial wildlife and plant species. Near the lake a limited ring of semi aquatic plants grow in association with spring and creek waters. Agriculture lands are used as pasture and to grow feed crops such as hay and alfalfa. Larger stream inflows host riparian and aquatic meadow plants. The low hills of the valley support sagebrush, grasslands, pinion, juniper, maple, and brushy communities. In the higher mountains brushes give way to large tree complexes of aspen, spruce, pine, and their associated undergrowths. The …

Paleo-Biology And Paleo-Hydrology Of The Bear Lake Basin, Utah, Patsy Palacios, Chris Luecke, Justin Robinson

Natural Resources and Environmental Issues

Many ancient clam and snail shells have been found around the shoreline of Bear Lake. Local residents have at times gathered the shells as a source of calcium for their chickens. These shells are well preserved and have been dated to be 10,000 years old (Smart, 1963). Curators at the Smithsonian Institute identified all 6 species of snail and one species of clam. Carbon dating performed by Columbia University estimated shells gathered from the Ideal Beach area of Bear Lake to be 12,000 years old....

Winning By A Neck: Tall Giraffes Avoid Competing With Smaller Browsers, E. Z. Cameron, Johan T. Du Toit Jan 2007

Winning By A Neck: Tall Giraffes Avoid Competing With Smaller Browsers, E. Z. Cameron, Johan T. Du Toit

Wildland Resources Faculty Publications

With their vertically elongated body form, giraffes generally feed above the level of other browsers within the savanna browsing guild, despite having access to foliage at lower levels. They ingest more leaf mass per bite when foraging high in the tree, perhaps because smaller, more selective browsers deplete shoots at lower levels or because trees differentially allocate resources to promote shoot growth in the upper canopy. We erected exclosures around individual Acacia nigrescens trees in the greater Kruger ecosystem, South Africa. After a complete growing season, we found no differences in leaf biomass per shoot across height zones in excluded …

Differentiation For The Gifted In American Islamic Schools, F. A. K. Al-Lawati, Scott L. Hunsaker

Teacher Education and Leadership Faculty Publications

A brief narrative description of the journal article, document, or resource. This research focuses on teacher instructional and curricular practices in gifted students' experiences in Islamic schools in the United States. Surveys were administered at private, full-time Islamic elementary schools to determine the extent to which differentiation practices for meeting the needs of gifted students and the integration of Islamic values were employed. Findings suggest that Islamic schools in the United States have limited programs for gifted students. A majority of teachers in Islamic schools differentiate little between gifted and average students in instructional strategies. When differentiation occurs, it is …

Relative Role Of Understory And Overstory In Carbon And Nitrogen Cycling In A Southern Appalachian Spruce-Fir Forest, P. T. Moore, H. Van Miegroet, N. S. Nicholas

Watershed Sciences Faculty Publications

This study investigated aboveground pools and fluxes of biomass, carbon (C), and nitrogen (N) in the overstory and understory of a southern Appalachian red spruce (Picea rubens Sarg.) – Fraser fir (Abies fraseri (Pursh) Poir.) forest, following adelgid-induced fir mortality and spruce windthrow. Using fifty 20 m × 20 m plots, stratified by elevation (1700–1900 m), we estimated standing biomass and fluxes of all growth forms from periodic stand inventories (1998–2003), vegetation surveys, and existing or derived allometric equations. Total C and N pools and fluxes were calculated from plant- and tissue-specific C and N concentrations. Total aboveground biomass attained …

Soil Organic Carbon Dynamics Along A Climatic Gradient In A Southern Appalachian Spruce-Fir Forest, C. E. Tewksbury, H. Van Miegroet

Watershed Sciences Faculty Publications

A field study was conducted in a high-elevation spruce–fir (Picea rubens Sarg. – Abies fraseri (Pursh.) Poir) forest in the Great Smoky Mountains National Park to assess the effect of temperature on soil C storage and dynamics. In eight plots along an elevation gradient (1500–1900 m), we measured soil temperature, forest floor and mineral soil C, litter decomposition, soil respiration, and forest floor mean residence time. Mean annual soil temperature and annual degree-days above 5 °C were inversely correlated with elevation. Total soil C (166–241 Mg·ha–1) showed no trend with elevation, while forest floor C accumulation (16.3–35.9 Mg·ha–1) decreased significantly …

Successful Use Of Neck Snares To Live-Capture Red Foxes, S. Nicole Frey, Michael R. Conover, Gary Cook Jan 2007

Successful Use Of Neck Snares To Live-Capture Red Foxes, S. Nicole Frey, Michael R. Conover, Gary Cook

Human–Wildlife Interactions

Box traps and foot-hold snares are common methods to live-capture study animals. However, these methods are frequently ineffective due to factors such as weather constraints, food availability, and target animal behavior. During a study of red fox (Vulpes vulpes) behavior, we examined the use of neck snares to live-trap study animals. We modified the neck snare using swivel cam-locks, deer stops to minimize damage to the animal. Additionally, we utilized our knowledge of red-fox behavior to set traps in a way that would reduce trauma to the captured animals. We snared 21 red foxes during the 3-year study …

Comparison Of Sampling Strategies To Estimate Abundance Of Double-Crested Cormorants In Western Mississippi, Aaron T. Pearse, Brian S. Dorr, Stephen J. Dinsmore, Richard M. Kaminski Jan 2007

Comparison Of Sampling Strategies To Estimate Abundance Of Double-Crested Cormorants In Western Mississippi, Aaron T. Pearse, Brian S. Dorr, Stephen J. Dinsmore, Richard M. Kaminski

Human–Wildlife Interactions

We compared 2 sampling strategies designed to estimate abundance of double-crested cormorants (Phalacrocorax auritus, hereafter cormorants) on aquaculture ponds in western Mississippi. Cormorants are a major predator of cultured channel catfish (Ictalurus punctatus) in this region; thus, estimating cormorant abundance is needed to better determine their economic impact. We independently designed a species-specific survey (i.e., cluster sampling) and a general survey (i.e., transect sampling) based on robust probability sampling theory to estimate abundance of this target population. During winters 2002–2003 and 2003–2004, we conducted 8 pairs of surveys and compared estimates of cormorant abundance and associated …

Perceptions Of Wildlife Damage And Species Conservation: Lessons Learned From The Utah Prairie Dog, R. Dwayne Elmore, Terry A. Messmer, Mark W. Brunson Jan 2007

Perceptions Of Wildlife Damage And Species Conservation: Lessons Learned From The Utah Prairie Dog, R. Dwayne Elmore, Terry A. Messmer, Mark W. Brunson

Human–Wildlife Interactions

The Utah prairie dog (Cynomys parvidens), a federally listed threatened species, causes damage to agricultural operations, yet little incentive exists for private landowners to conserve them. Therefore, we surveyed Utah residents to identify stakeholder attitudes regarding prairie dog management. We assessed how perceptions of wildlife damage affect respondent attitudes regarding conservation among agricultural producers, rural residents, and urban residents. Higher levels of perceived wildlife damage were reported for agriculture respondents (79%) than for urban (20%) or rural (45%) respondents. Compensation for damage caused by Utah prairie dogs was supported by those engaged in agricultural production but not by …

Foraging Preferences Of Captive Canada Geese Related To Turfgrass Mixtures, Brian E. Washburn, Scott C. Barras, Thomas W. Seamans Jan 2007

Foraging Preferences Of Captive Canada Geese Related To Turfgrass Mixtures, Brian E. Washburn, Scott C. Barras, Thomas W. Seamans

Human–Wildlife Interactions

Overabundant populations of Canada geese (Branta canadensis) cause economic and safety concerns associated with collisions with civil and military aircraft. Habitat management techniques that reduce the use of airfield habitats by geese might reduce these concerns. The objective of this study was to determine if captive Canada geese exhibited a foraging preference between a vegetation mixture consisting mostly of perennial ryegrass (Lolium perenne) and white clover (Trifolium repens) versus an endophyte-infected tall fescue- (Festuca arundinacea) based vegetation mixture. We established 6 paired plots of perennial ryegrass-dominated and tall fescue-dominated mixtures at NASA …

Spatially Scaled Response Of A Lazuli Bunting Population To Fire, Michael L. Wolfe, Andreas Leidolf, Tim Nuttle Jan 2007

Spatially Scaled Response Of A Lazuli Bunting Population To Fire, Michael L. Wolfe, Andreas Leidolf, Tim Nuttle

Wildland Resources Faculty Publications

We examined the response of Lazuli Bunting (Passerina amoena) to fire in Gambel oak (Quercus gambelii) woodland at Camp Williams, Utah, during 1993–1998. Overall, Lazuli Bunting abundance on the study area increased significantly during the 2 years after a stand-replacing wildfire, which covered 800 ha of Gambel oak woodland. This increase suggested that Lazuli Buntings respond positively to fire. However, a comparison of pre- and post-fire abundance of Lazuli Bunting for 2 groups of monitoring plots with different fire histories showed that abundance was significantly greater during the post-fire period for both burned and unburned plots. …

Experimental Evidence For An Alkali Ecotype Of Lolium Multiflorum, An Exotic Invasive Annual Grass In The Central Valley, Ca, Usa, K. Dawson, Kari E. Veblen, T. P. Young Jan 2007

Experimental Evidence For An Alkali Ecotype Of Lolium Multiflorum, An Exotic Invasive Annual Grass In The Central Valley, Ca, Usa, K. Dawson, Kari E. Veblen, T. P. Young

Wildland Resources Faculty Publications

One of the characteristics of highly invaded ecosystems is that invasive species are often poor invaders of edaphically severe sites, which become refuges for native flora. To investigate the invasive potential of Lolium multiflorum (Hick.) into alkali sites in California, an ex-situ reciprocal transfer experiment was carried out using seeds from populations of L. multiflorum taken from three sites differing in alkalinity (and inundation), including alkali sink soils (pH 8.5) and sink-edge soils (pH 7.4) located within meters of each other, and non-sink soils (pH 5.0) located several km away. Survivorship, plant height, leaf number and seed production were assessed. …

Random Forests For Classification In Ecology, D. R. Cutler, Thomas C. Edwards Jr., Karen H. Beard, A. Cutler, K. T. Hess, J. C. Gibson, J. J. Lawler Jan 2007

Random Forests For Classification In Ecology, D. R. Cutler, Thomas C. Edwards Jr., Karen H. Beard, A. Cutler, K. T. Hess, J. C. Gibson, J. J. Lawler

Wildland Resources Faculty Publications

Classification procedures are some of the most widely used statistical methods in ecology. Random forests (RF) is a new and powerful statistical classifier that is well established in other disciplines but is relatively unknown in ecology. Advantages of RF compared to other statistical classifiers include (1) very high classification accuracy; (2) a novel method of determining variable importance; (3) ability to model complex interactions among predictor variables; (4) flexibility to perform several types of statistical data analysis, including regression, classification, survival analysis, and unsupervised learning; and (5) an algorithm for imputing missing values. We compared the accuracies of RF and …
