Effects Of Browsing By Native Ungulates On The Shrubs In Big Sagebrush Communities In Yellowstone National Park, Francis J. Singer, Roy A. Renkin

Great Basin Naturalist

The effects of elk (Cervus elaphus), pronghorn (Antilocapra americana), and mule deer (Odocoileus hemionus) browsing on shrubs in big sagebrush (Artemisia tridentata) communities were monitored over a 31-year period in Yellowstone National Park. Ungulates were restricting Wyoming big sagebrush (spp. wyomingensis) heights, size, and recruitment on the lower-elevation stratum only, while no such suppression was observed on the high-elevation stratum. Parallel increases in mountain big sagebrush (spp. vaseyana) densities and cover occurred over the study period on both browsed and unbrowsed sites at the higher-elevation stratum, although big sagebrush, green …

Real-Time Three-Dimensional Display Based On The Partial Pixel Architecture, Gregory P. Nordin, M. W. Jones, S. T. Kowel, J. H. Kulick, R. G. Lindquist

Faculty Publications

We previously reported several static three-dimensional (3-D) display implementations of the partial pixel architecture [J. Opt. Soc. Am. A 12, 73 (1995)]. We report herein our f irst real-time 3-D display based on this architecture. The display is functionally equivalent to a real-time holographic stereogram. It is autostereoscopic and provides horizontal motion parallax. The display device is composed of a diffractive optical element (fabricated with standard photolithographic techniques) and a separate conventional liquidcrystal display. The display has been used to play back a precomputed animated 3-D scene at video frame rates using a standard VGA video output.

Stomatal Characterization Of Grass Leaves By Four Preparation Techniques, Val J. Anderson, John S. Gardner, Joyce Phillips Hardy

Faculty Publications

Four leaf preparation techniques (air drying, tetramethylsilane air drying, critical point drying, and freeze substitution) used in scanning electron microscopy (SEM) were evaluated with respect to the degree of cellular distortion they produce in stomatal guard cells of leaves of Dactylis glomerata and Elymus canadensis. Surface morphological distortion and cuticle disruption in the air-dried and tetramethylsilane air-dried leaves, and cuticle disruption within the critical point-dried tissue made it difficult to obtain measurements.The freeze-substituted tissue experienced little cuticle disturbance, and the cellular morphology appeared normal. The length of the guard cells did not significantly differ between the air-dried, tetramethylsilane air-dried, critical …

Invertebrate Fauna Of Wastewater Ponds In Southeastern Idaho, Karen L. Cieminski, Lester D. Flake

Great Basin Naturalist

Water column invertebrates were sampled with 3.8-L activity traps in 15 sewage, industrial, and radioactive wastewater ponds at the Idaho National Engineering Laboratory in southeastern Idaho. One collection was made per pond, per month, during all months the ponds were ice-free from June 1990 through July 1991. Arsenic, barium, boron, lead, selenium, and mercury were detected in ponds. Sewage ponds generally had higher nitrogen and phosphorus levels than industrial and radioactive ponds. Of the 30 aquatic invertebrate taxa collected, the most ubiquitous were Rotifera, Daphnidea, Eucopepdoa, Ostracoda, Acari, Baetidae, Corixidae, Notonectidiae, Dytiscidae, and Chironomidae. Activity trap samples from sewage ponds …

Demography Of Astragalus Scaphoides And Effects Of Herbivory On Population Growth, Peter Lesica

Great Basin Naturalist

Losses in fecundity due to predispersal herbivory can be large; however, the effects of this loss on long-term population viability have rarely been investigated. I conducted a demographic study of Astragalus scaphoides (Fabaceae), a long-lived perennial endemic to east central Idaho and adjacent Montana, by following mapped individuals at two sites from 1986 to 1993. Astragalus scaphoides suffers losses of predispersal fecundity averaging nearly 50% from insect seed predation and inflorescence predation by insects and livestock. Cattle reduced fecundity by 0–85%. Nonetheless, estimates from matrix projection models indicate that both sample populations had positive growth in most years. Elasticity analyses …

Lahontan Sagebrush (Artemisia Arbuscula Ssp. Longicaulis): A New Taxon, Alma H. Winward, E. Durant Mcarthur

Great Basin Naturalist

A new subspecies of Artemisia arbuscula is described, A. arbuscula ssp. longicaulis Winward & McArthur, ssp. nov. This taxon is a landscape dominant in portions of northwestern Nevada and adjacent California and Oregon at elevations from 1050 to 2000 m on shallow or argillic (clayey) soils. It differs from A. arbuscula ssp. arbuscula in its long floral stalks and large leaves. Morphological, chemical, ecological, and cytological data suggest that it is of hybrid origin. It is hexaploid (6x). We hypothesize that 2x A. arbusucla ssp. arbusucla and 4x A. tridentata ssp. wyomingensis are its parents.

Diets Of Young Colorado Squawfish And Other Small Fish In Backwaters Of The Green River, Colorado And Utah, Robert T. Muth, Darrel E. Snyder

Great Basin Naturalist

We compared diet of young-of-year Colorado squawfish (Ptychocheilus lucius), an endangered cyprinid, with diets of other fish < 75 mm total length (TL) collected from backwaters of the Green River between river kilometers 555 and 35 during summer and autumn 1987. Species included native Rhinichthys osculus, Catostomus discobolus, and C. latipinnts, and nonnative Cyprinella lutrensis, Notropis stramineus, Pimephales promelas, Ictalurus punctatus, and Lepomis cyanellus. For each species, diet varied with size and between upper and lower river reaches but not between seasons for fish of similar size. Larval chironomids and ccratopogonids were principal foods of most fishes. Copepods and cladocerans were important in diets of P. lucius < 21 mm TL and L. cyanellus < 31 mm TL. Catostomus discobolus was the only species that ate moderate amounts of algae. Fish (all larvae) …

Factors Affecting Selection Of Winter Food And Roosting Resources By Porcupines In Utah, Dave Stricklan, Jerran T. Flinders, Rex G. Cates

Great Basin Naturalist

Ecological and phytochemical factors potentially affecting winter dietary discrimination by porcupines (Erethizon dorsatum) in the mountain brush zone of Utah were studied. Porcupines utilized gambel oak (Quercus gambelii) as their primary winter food and roosting resource. Big-tooth maple (Acer grandidentatum) was the most common tree species in the study area but was rarely utilized by porcupines. Conifer species were used as a food and roosting resource significantly less often than they occurred in the study area, despite thermal advantages provided by their relatively dense canopies. Oak feed trees were successfully separated from conifer feed …

Whipworm (Trichuris Dipodomys) Infection In Kangaroo Rats (Dipodomys Spp.): Effects On Digestive Efficiency, James C. Munger, Todd A. Slichter

Great Basin Naturalist

To determine whether infections by whipworms (Trichuris dipodomys [Nematoda: Trichurata: Trichuridae]) might affect digestive efficiency and therefore energy budgets of two species of kangaroo rats (Dipodomys microps and Dipodomys ordii [Rodentia: Heteromyidae]), we compared the apparent dry matter digestibility of tree groups of hosts: those naturally infected with whipworms, those naturally uninfected with whipworm, and those originally naturally infected but later deinfected by treatment with the anthelminthic Ivermectin. Prevalence of T. dipodomys was higher in D. microps (53%) than in D. ordii (14%). Apparent dry matter digestibility was reduced by whipworm infection in D. microps but not in …

Pollinator Sharing By Three Sympatric Milkvetches, Including The Endangered Species Astragalus Montii, S. M. Geer, V. J. Tepedino, T. L. Griswold, W. R. Bowlin

Great Basin Naturalist

Insects visiting flowers of the endangered Heliotrope milkvetch, Astragalus montii, were compared with those visiting two common sympatric congeners, A. kentrophyta and A. miser, on three sites on the Wasatch Plateau of central Utah for 2 yr. We recorded 27+ species of bees, most of which were uncommon, visiting the three species. All three species were primarily visited by native bees of the genera Osmia (15 species) and/or Bombus (4 species). Most Osmia species visited the three species of Astragalus indiscriminantly; bumblebees preferred A. miser and avoided A. montii. Our hypothesis that A. montii flowers would receive …

Local Distribution And Foraging Behavior Of The Spotted Bat (Euderma Maculatum) In Worthwestern Colorado And Adjacent Utah, Jay F. Storz

Great Basin Naturalist

This study investigated local distribution and foraging behavior of the spotted bat (Euderma maculatum) in Dinosaur National Monument, Colorado-Utah, by monitoring audible echolocation calls. The occurrence of this species was verified in a variety of habitat types in canyon bottoms and other relatively low elevation sites, indicating that the animals were widely distributed and locally common in the area. Foraging spotted bats concentrated flight activity in the open-air space above meadows occasionally exploited near-canopy habitat (within 8 m of foliage). Bats began to forage shortly after dark, and activity levels were relatively constant throughout the night. Foraging spotted …
