Newly Revealed Diversity Of Green Microalgae From Wilderness Areas Of Joshua Tree National Park (Jtnp), Valerie R. Flechtner, Nicole Pietrasiak, Louise A. Lewis

Monographs of the Western North American Naturalist

Documentation of the biodiversity of eukaryotic algae from desert systems is sparse. Our objective was to characterize microalgae from soil samples collected throughout Joshua Tree National Park, California, USA. Morphological, life-cycle, and DNA sequence data were collected for 100 microalgal isolates distributed over 18 sites in Joshua Tree National Park. Phylogenetic analysis of the 18S rDNA data separated the green algae into 15 major clades—10 in the class Chlorophyceae and 5 in the class Trebouxiophyceae—containing 2 or more lineages plus 9 lineages represented by a single isolate. Five isolates belonging to the class Xanthophyceae and 2 isolates belonging to Eustigmatophyceae …

Hell On The Range: A Story Of Honor, Conscience, And The American West, Daniel J. Herman, Taunalyn F. Rutherford

BYU Studies Quarterly

In the introduction to Hell on the Range, Daniel Justin Herman informs readers that his account of Arizona's Rim Country War of the 1880s is more than revisionist critique; it is self-critique. Herman, an associate professor of history at Central Washington University, is an Arizonan who, like many growing up in the western United States, was "raised on its romance," and in his youth he viewed "Arizonans--especially cowboys--[as] made of sterner, stronger stuff than people who grew up elsewhere" (xxii). His view of Mormons and Mormonism--an important undercurrent animating much of this book--was informed by his experiences as a non-Mormon …

On Mormon Laughter, Shawn R. Tucker

BYU Studies Quarterly

Shawn Tucker, an associate professor of fine arts, offers an interpretation on the scriptural injunctions against excessive and loud laughter found in Latter-day Saint scripture. Having grown up in a home with lots of joyous, good-natured laughter, the author recalls his confusion at such commands. His research explores the teachings of leaders of The Church of Jesus Christ of Latter-day Saints, sociologists, and great thinkers such as C. S. Lewis.

The article shows that laughter that is cold, cynical, and belittling is a perversion of a God-given faculty that should delightfully lift and edify. A good sense of humor can …

Preliminary Checklist Of Lichens Reported From Wyoming, Dorothy E. Tuthill

Monographs of the Western North American Naturalist

Although lichens are a common feature in Wyoming, there has been no attempt to compile a statewide list of species since 1900. A number of surveys have been conducted in the state, especially in Yellowstone National Park and other federally managed parks and forests, though little attention has been given to lower-elevation regions of the state. The literature search conducted for this project yielded nearly 800 species names, which number was reduced to 608 currently accepted taxa. Collection locations and references are provided for each taxon, as are global ranks (conservation status, from NatureServe.org), and a brief discussion of some …

Spatial And Temporal Variation Of Dissolved Oxygen And Ecosystem Energetics In Devils Hole, Nevada, Melody J. Bernot, Kevin P. Wilson

Western North American Naturalist

Devils Hole, a unique ecosystem in the Mojave Desert, is home to a few dominant species of algae and invertebrates as well as the endangered Devils Hole pupfish,Cyprinodon diabolis. With consistently high water temperature (33.5 °C/93 °F) and low dissolved oxygen (O₂) concentration (about 2.5 mg O₂ ⋅ L^–1), organisms are at the extremes of their physiological limits, and production of O₂ by microbial biofilms is essential to ecosystem stability. Water column O₂ concentrations were measured from July 2008 to March 2010 in the deep pool and shallow shelf habitats of Devils …

Cui-Ui Reproductive Success From Potential Egg Deposition To Larval Emigration, G. Gary Scoppettone, Peter H. Rissler

Western North American Naturalist

From 1985 to 2006, we tracked cui-ui, Chasmistes cujus, survival from potential egg deposition of migrating spawners to emigrating larvae. Tahoe sucker larvae emigrated to Pyramid Lake the same time as cui-ui larvae, but cui-ui was the predominant catostomid larvae we captured. Survival of cui-ui larvae ranged from 0.46% to 21.17%, declining significantly with decreased flow and increased number of spawners (P < 0.01). Mean total length of emigrating larvae ranged from 11.5 to 12.6 mm and may have been affected by stream flow. Removal of impediments to upstream migrating cui-ui spawners, along with sufficient stream flows, may enhance early life-stage survival.


Desde 1985 hasta 2006, rastreamos la supervivencia de peces cui-ui, Chasmistes cujus,de una posible deposición de huevos de hembras migratorias a larvas emigrantes. Las larvas del pez Tahoe sucker emigraron al Lago Pirámide al mismo tiempo que …

Biodiversity, Water Chemistry, Physical Characteristics, And Anthropogenic Disturbance Gradients Of Sandstone Springs On The Colorado Plateau, Rebecca H. Weissinger, Dustin W. Perkins, Eric C. Dinger

Western North American Naturalist

Springs located on the Colorado Plateau are highly threatened and represent a small percentage of the landscape; yet they are disproportionately important to diverse native flora and fauna. The relationships between anthropogenic disturbance, aquatic macroinvertebrate species composition, and environmental variables at these springs have received little study. We selectively visited 40 sandstone springs in southeastern Utah and southwestern Colorado to span a range of impacts. We classified the springs into impact categories based on a spring impact score, and we measured biodiversity (aquatic macroinvertebrates), water chemistry (nutrients, dissolved O₂, pH, specific conductivity, temperature, turbidity, coliform bacteria [Escherichia …

The Nest Predator Assemblage For Songbirds In Mono Lake Basin Riparian Habitats, Quresh S. Latif, Sacha K. Heath, Grant Ballard

Western North American Naturalist

Because nest predation strongly limits avian fitness, ornithologists identify nest predators to inform ecological research and conservation. During 2002–2008, we used both video-monitoring of natural nests and direct observations of predation to identify nest predators of open-cup nesting riparian songbirds along tributaries of Mono Lake, California. Video cameras at 50 nests of 3 songbird species and direct observations of additional nests confirmed 10 distinct nest-predator species and suggested one additional species. Video-monitored nests experienced reduced predation rates, and video observations mainly captured nestling predation, even though predation rates were higher for nonvideo-monitored nests during the egg period. These findings suggest …

Influence Of Relictual Species On The Morphology Of A Hybridizing Oak Complex: An Analysis Of The Quercus X Undulata Complex In The Four Corners Region, Ross A. Mccauley, Brenna J. Christie, Erik L. Ireland, Rae A. Landers, Haley R. Nichols, Matthew T. Schendel

Western North American Naturalist

The genus Quercus represents an important component of the scrublands and low forests of the Four Corners area of northeastern Arizona, southeastern Utah, southwestern Colorado, and northwestern New Mexico. The area is dominated by the widespread Quercus gambelii, although relictual and marginal populations of Q. turbinella and Q. havardii are also present. Hybridization among these 3 species is common, leading to much variability in phenotypic traits, and this hybridization forms part of the widespread complex of hybrid oaks recognized as Q. x undulata.Multivariate analysis of leaf morphology was performed in 9 populations, representing the various taxa and levels of …

Inundation Depth, Duration, And Temperature Influence Fremon Cottonwood (Populus Fremontii) Seedling Growth And Survival, L. C. Auchincloss, J. H. Richards, C. A. Young, M. K. Tansey

Western North American Naturalist

Fremont cottonwood (Populus fremontii) is an early successional foundation species found in riparian forest ecosystems in the North American Southwest. Along rivers, the upper limit of the seedling establishment zone depends on the proximity of seedling roots to the declining water table. The lower limit is a function of the maximum elevation of inundation or scour. Fremont cottonwood seedlings are likely to experience short-term (1- to 5-week) inundation during their first year of growth under both natural and human-influenced hydrologic regimes. Previous studies show that inundation can account for more than 70% of seedling mortality during this time. …

Salinity Of The Little Colorado River In Grand Canyon Confers Anti-Parasitic Properties On A Native Fish, David L. Ward

Western North American Naturalist

Water in the Little Colorado River within Grand Canyon is naturally high in salt (NaCl), which is known to prohibit development of external fish parasites such as Ich (Ichthyophthirius multifiliis). The naturally high salinity (>0.3%) of the Little Colorado River at baseflow may be one factor allowing survival and persistence of larval and juvenile humpback chub (Gila cypha) and other native fishes in Grand Canyon. We compared salinity readings from the Little Colorado River to those reported in the literature as being effective at removing protozoan parasites from fish. In laboratory tests, 10 juvenile roundtail …

Olfactory Detection Of Caches Containing Wildland Versus Cultivated Seeds By Granivorous Rodents, Jennifer L. Hollander, Stephen B. Vander Wall, William S. Longland

Western North American Naturalist

We conducted a study to examine the ability of granivorous rodents to detect caches made with wildland (native and nonnative) and cultivated seeds at 3 locations in western Nevada with different vegetation types and rodent community structures. We established artificial caches containing either 2 or 3 species of wildland seeds or cultivated seeds. Five seed species were tested at each site. Under dry conditions, rodents found caches containing cultivated seeds much more rapidly than caches containing wildland seeds. Wet conditions resulted in a similar order of detectability; however, all species of seeds were located much faster in wet conditions than …

The Diet Of Western Burrowing Owls In An Urban Landscape, Lynne A. Trulio, Philip Higgins

Western North American Naturalist

While we know much about the diet of Western Burrowing Owls (Athene cunicularia hypugaea) in many of their more natural habitats, little is known about their diets in urban environments. We analyzed pellets and prey remains collected at burrows used by Burrowing Owls living in urban grasslands in Santa Clara County, California. We hypothesized that the composition of prey species in the diet of these urban owls would differ from that of owls living in agricultural and more-natural western habitats and, in particular, that rodents would be a smaller component of the diet. We found the invertebrate-to-vertebrate ratio …

Population Abundance And Sex Ratio Of The Viviparous Freshwater Fish Poeciliopsis Baenschi (Poeciliidae) Throughout Its Range In Western Mexico, J. Jaime Zúñiga-Vega, Ana L. Hernández-Rosas, Alejandro Molina-Moctezuma, Hibraim A. Pérez-Mendoza, Fernanda R. Rodríguez-Reyes, Yolotzin M. Bravo-Espinosa, Héctor Espinosa-Pérez

Western North American Naturalist

We estimated population abundance and sex ratio for a freshwater live-bearing fish species (Poeciliopsis baenschi) that inhabits fluvial systems in western Mexico. We conducted mark-recapture experiments in 6 distinct populations. We used both our catch data as well as estimates of capture probability to calculate the number of individuals per unit water volume for adult males, adult females, and juveniles. Overall, abundance varied among sites from 23.8 individuals · m^–3 to 363.2 individuals · m^–3. In most of our study sites, the estimated sex ratio was markedly biased toward females (up to 11 females per …

Taxonomic Clarification Of Lupinus Oreganus And Lupinus Biddlei In The Pacific Northwest, Usa, Paul M. Severns, Stephen C. Meyers, Tri Tran

Western North American Naturalist

Through a phylogenetic study using LEGCYC1A nucleotide sequences and a survey of historical botanical literature, we propose clarifications in the nomenclature of Lupinus oreganus and Lupinus biddlei. The former taxon has been incorrectly classified asLupinus sulphureus ssp. kincaidii and recently as L. oreganus var. kincaidii. The latter has recently been incorrectly delimited as L. oreganus var. oreganus.


Se proponen aclaraciones en la nomenclatura de Lupinus oreganus y Lupinus biddlei a través de un estudio filogenético que utiliza secuencias nucleótidas de LEGCYC1A y una revisión de literatura botánica histórica. El primer taxón mencionado se ha clasificado incorrectamente como Lupinus sulphureus …

Underwood's Bonneted Bat (Eumops Underwoodi): First Record In The Baja California Peninsula, Patricia Cortés-Calva, Sergio Ticul Álvarez-Castañeda, Julio M. Hernández-Gutirérrez, Marya De La Paz Cuevas

Western North American Naturalist

This paper reports the first record of Eumops underwoodi in the Baja California peninsula. This record expands the species’ distributional range in Mexico along the peninsula. We propose 2 plausible biogeographical explanations. First, the species has the ability to travel across the Gulf of California from the coast of Sonora to the eastern side of the Baja California peninsula and there establish. Second, there is a continuous distribution of the species throughout the mountain ranges that run longitudinally along the Baja California peninsula from the United States border down to the southern tip. We collected one male specimen of E. …

The Ideas Of Jean Piaget: Using Theory To Better Understand Theory And Improve Learning, William E. Herman

Swiss American Historical Society Review

M ost readers will note the irony embedded in the title of this paper and the Einstein quote. There is an obvious and important thread of truth derived from such premises. Is it prudent and scholarly to employ Jean Piaget's theory in order to more deeply explore the meaning of Piaget's theory? Biblical scholars have long been known to use the writings of the Apostles and other Biblical voices as tools to understand sacred text. In this way, the Bible is used to understand the Bible. As the Swiss theologian Karl Barth once stated regarding the daring element of Christian …

Albert Einstein In Switzerland: The Education Of The Most Famous Swiss American, Kurt Winkler

Swiss American Historical Society Review

The most famous Swiss American, by far, was Albert Einstein. It is well known that Einstein worked in Germany starting in 1914, but he was forced to leave in 1933 as someone the Nazis had "not yet hanged," and he came to the United States where he taught at Princeton University for many years. However, Einstein had earlier lived in Switzerland for many years. Even though he became an American citizen in 1940, the great physicist retained ties to Switzerland, and he kept his Swiss passport all his life . Einstein spent his most productive years in Switzerland where he …
