Effects Of Rotational Grazing On Rodents And Raptors In A Coastal Grassland, Matthew D. Johnson, Christa M. Horn

Western North American Naturalist

We conducted a 4-year experiment to assess the impacts of rotational cattle grazing on rodents and raptors in a mesic coastal grassland in northwestern California. Live-trapping indicated that rodent abundance declined by 69% on the grazed area and increased by 14% on the ungrazed area. Raptor use of the grazed area declined by 15% and increased on the ungrazed area by 63%. Measures of giving-up density indicated that rodents perceived a 25% higher predation risk on grazed area than on ungrazed area, but raptor hunting surveys indicated that risk of depredation from raptors was 2.5 times lower in the grazed …

Short-Term Effects Of Wildfire On Montane Stream Ecosystems In The Southern Rocky Mountains: One And Two Years Post-Burn, Sharon J. Hall, Danica Lombardozzi

Western North American Naturalist

The frequency and intensity of wildfire in the western United States has increased over the last century, creating a heterogeneous mosaic of landscapes in various stages of recovery. The 2002 Hayman Fire was one of the largest wildfires in Colorado history and was unprecedented for its speed and intensity, with over 50%–70% of the burn area classified as moderate to high severity where much of the canopy crown was consumed. We evaluated the short-term impact of the Hayman Fire on ecological properties in montane stream ecosystems in the summers of 2003 and 2004, one and two years post-fire. Fire significantly …

Water Stress And Hybridization Between Quercus Gambelii And Quercus Grisea, Nathan G. Swenson, Jeanne M. Fair, Jeff Heikoop

Western North American Naturalist

The historical and environmental forces involved in determining the geographic location of plant hybrid zones have long been of interest. Often hybrid zones appear to be intimately tied to the environment, yet because many abiotic factors covary it is often difficult to understand which are truly the most important in maintaining the position and structure of a hybrid zone. This study uses empirical data and modeling analyses to examine whether abiotic factors are responsible for the location and structure of an oak (Quercus) hybrid zone and, if so, which factors are the most important. Specifically, leaf trait measurements …

Gizzard Shad (Dorosoma Cepedianum) Expansion And Reproduction In The Upper Colorado River Basin, Sam T. Finney, Mark H. Fuller

Western North American Naturalist

Gizzard shad (Dorosoma cepedianum) were introduced into the Colorado River Basin circa 1996 via an unintentional contaminated stocking. Gizzard shad were collected throughout much of the Upper Colorado River Basin in 2005, 2006, and 2007. These collections document a rapid range expansion of this introduced species and a threat to intact fisheries.

Diet And Sexual Dimorphism Of The Desert Iguana, Dipsosaurus Dorsalis, From Sonora, Mexico, Christopher J. Dibble, Geoffrey R. Smith, Julio A. Lemos-Espinal

Western North American Naturalist

We examined the diet and sexual dimorphism of the desert iguana, Dipsosaurus dorsalis, from Sonora, Mexico. The diet consisted primarily of vegetation, with insect material contributing little to the overall volume of the diet. Plant matter was restricted to leaves and seeds. Animal prey consisted mostly of ants, termites, and beetles. Males and females did not differ significantly in snout–vent length, head length, or head width. These results confirm that in general D. dorsalis is herbivorous and not sexually dimorphic through much of its range.

Reproduction By June Sucker In A Refuge Population: Successful Spawning In A Lake Habitat, Eric J. Billman

Western North American Naturalist

The June sucker (Chasmistes liorus) is an endangered lake sucker endemic to Utah Lake, Utah. As part of recovery actions, June suckers were introduced into Red Butte Reservoir, Utah, as a wild grow-out site. Since their introduction, June suckers have successfully reproduced in Red Butte Reservoir, producing a large population in this refuge. I used passive egg collectors (egg traps and nets) and observational surveys to determine the location of spawning sites within the reservoir, and larval light trapping to determine successful recruitment (i.e., egg survival through larval swim-up) at these sites. Eggs were collected between 18 June …

"Pando" Lives: Molecular Genetic Evidence Of A Giant Aspen Clone In Central Utah, Jennifer Dewoody, Carol A. Rowe, Valerie D. Hipkins, Karen E. Mock

Western North American Naturalist

While clones of trembling aspen (Populus tremuloides, Michx.) in the Intermountain West of North America are expected to be large, one putative genet in central Utah, identified from morphological evidence, has garnered particular attention for its size, even gaining the nickname "Pando" (Latin for "I spread"). In order to determine if a single genetic individual coincides with the morphological boundary of "Pando," we sampled 209 stems on a 50-m grid throughout the putative clone for analysis at 7 microsatellite loci. We have identified a single genetic entity concurrent with that described from morphological characteristics. Spatial analyses indicate that the …

Lost Generations? Indigenous Population Of The Russian North In The Post-Soviet Era, Andrey N. Petrov

Faculty Publications

This paper discusses key findings concerning population dynamic of the Indigenous minorities living in the Russian North during the post-Soviet period, highlighted by the 2002 Census. The paper places recent demographic trends into the context of past and current economic, social and institutional changes. It also provides comparisons with Indigenous population dynamics in other parts of the Arctic. Although most Indigenous peoples of the Russian North were growing numerically, they still experienced effects of Russia’s economic crisis, primarily reflected in rapidly falling fertility and rising mortality in the middle-age cohorts. In addition, both the ethnic drift and legal changes seriously …

An Equation For Estimating The (R) Usle Slope Steepness Factors, Mathew Mulemgera

Tanzania Journal of Engineering and Technology (TJET)

Abstract Currently three equations are used for calculating slope steepness factor for the Revised Universal Soil Loss Equation (RUSLE); one for slopes less than nine percent, the second for slopes equal or greater than nine percent, and the third equation that has been proposed for use in China for slopes equal or greater than 17 %. The three equations have linear relationships between slope steepness factor, S and the sine of the slope angle, θ. The three equations under predict the factor, S when used on slope steepness beyond the data sets used to develop them. In addressing this problem …

Distribution And Status Of The Yellow-Faced Pocket Gopher In Kansas, Justin D. Hoffman, Jerry R. Choate

Western North American Naturalist

Previous research suggests that the yellow-faced pocket gopher (Cratogeomys castanops) occupies a restricted range in western Kansas that is surrounded by the range of the plains pocket gopher (Geomys bursarius), which is regarded as a superior competitor. To determine whether the plains pocket gopher has encroached on the range of the yellow-faced pocket gopher in the past 35 years and to better understand the geographic relationships of these species, we trapped pocket gophers in western Kansas and collected soil texture and land cover data. We used ArcView 3.2 to map the distributions of these species in …

The Dystopian Potential Of Corporate Law, D. Gordon Smith

Faculty Scholarship

The community of corporate law scholars in the United States is fragmented. One group, heavily influenced by economic analysis of corporations, is exploring the merits of increasing shareholder power vis-a-vis directors. Another group, animated by concern for social justice, is challenging the traditional, shareholder-centric view of corporate law, arguing instead for a model of stakeholder governance. The current disagreement within corporate law is as fundamental as in any area of law, and the debate is more heated than at any time since the New Deal. This paper is part of a debate on the audacious question, Can Corporate Law Save …

Review Of Patrick Heelan, Space-Perception And The Philosophy Of Science, Cliff Hooker

Research Resources

Heelan has taken a rich philosophical framework and within its categories woven a marvellously detailed and wondrously wide tapestry. That tapestry includes an exciting illumination of Western art and pictorial understanding generally; the sweep of history, scientific and cultural; the enterprise of science and the nature and roles of technology in both science and culture. Heelan's book then has interest at several different levels; in ascending order: there are the specific theses about vision and about science; there is the connecting of philosophy of visual art and philosophy of science; there is Heelan's attempt to set both of these latter …

Taiwan Top Five, Paul Katz

China Beat Blog: Archive 2008-2012

As we prepare to ring out 2008, here are a few thoughts about some of the leading stories that have shaped Taiwan during the past year:

1. Back and Blue: Ma Ying-jeou sweeps into office as Taiwan’s new president, winning a convincing majority of the popular vote based on a platform promising a more stable relationship with China, economic prosperity, and clean government. Cross-Straits tensions have declined markedly, while the opening of direct links should bring great benefits to the citizens of both China and Taiwan. At the same time, however, the economy remains in the doldrums (see #2) …
