Brood-Rearing Habitat Use By Rio Grande Wild Turkeys In Oregon, Thomas W. Keegan, John A. Crawford Jul 1997

Brood-Rearing Habitat Use By Rio Grande Wild Turkeys In Oregon, Thomas W. Keegan, John A. Crawford

Great Basin Naturalist

Wild turkey (Meleagris gallopavo) brood-rearing sites have been described for portions of their range, but brood-rearing habitat use and characteristics of brood-rearing sites used by Rio Grande Wild Turkeys (M. g. intermedia) in the Pacific Northwest were unknown. We described cover types at 362 brood-rearing sites and measured habitat characteristics at 64 of these sites used by a recently established Rio Grande Wild Turkey population in southwestern Oregon during May–September 1989 and 1990. Hens with broods used 9 of 10 available cover types. Meadows, mixed hardwood/conifer woodlands, and savannas were used more often than expected (47% …

Stick Nests On A Building And Transmission Towers Used For Nesting By Large Falcons In Utah, Stephen T. Bunnell, Clayton M. White, Don Paul, S. Dwight Bunnell Jul 1997

Stick Nests On A Building And Transmission Towers Used For Nesting By Large Falcons In Utah, Stephen T. Bunnell, Clayton M. White, Don Paul, S. Dwight Bunnell

Great Basin Naturalist

Large falcons (genus Falco) do not build their own nests and, in North America at least, usually nest on high cliffs. Occasionally they nest in abandoned stick nests built by another large bird on the cliff. In Asia and particularly South Africa, they sometimes nest in stick nests on electrical transmission towers. This use of electric transmission towers was recently (1980) reported for the Prairie Falcon (Falco mexicanus) in North America but is unknown, except for 1 anecdotically documented use of an "electric-power pole" at the turn of century in California, for the Peregrine Falcon (Falco …


Effects Of Myofibrogranuloma On Serum Calcium Levels In Walleye (Stizostedion Vitreum), Craig A. Shoemaker, Harry L. Holloway Jr. Jul 1997

Effects Of Myofibrogranuloma On Serum Calcium Levels In Walleye (Stizostedion Vitreum), Craig A. Shoemaker, Harry L. Holloway Jr.

Great Basin Naturalist

The effect of myofibrogranuloma (skeletal muscle degeneration) on serum calcium levels in spawning walleye (Stizostedion vitreum) was examined. Mean serum calcium levels for healthy male walleye (11.7 ± 1.5 mg/100 ml serum) was significantly lower (P < 0.05) than calcium levels for healthy female walleye (15.4 ± 1.8 mg/100 ml serum). Significant increases (P < 0.1) in serum calcium were seen between healthy male and myofibrogranuloma-diseased male walleye (13.6 ± 2.1 mg/100 ml serum) and between healthy and myofibrogranuloma-diseased female walleye (20.2 ± 3.7 mg/100 ml serum). Elevations seen in mean serum calcium levels suggest the muscle degeneration and subsequent granuloma formation in later stages of myofibrogranuloma have a significant effect on serum calcium.


Distribution Of The Milliped Tylobolus Utahensis Chamberlin, With Remarks On T. Fredericksoni (Causey) (Spirobolida: Spirobolidae), Rowland M. Shelley, Selena B. Bauer Jul 1997

Distribution Of The Milliped Tylobolus Utahensis Chamberlin, With Remarks On T. Fredericksoni (Causey) (Spirobolida: Spirobolidae), Rowland M. Shelley, Selena B. Bauer

Great Basin Naturalist

Tylobolus utahensis Chamberlin, the only representative of the genus occurring in the southwestern deserts, ranges from central Inyo County, California, to the western periphery of Kane County, Utah. This distribution roughly corresponds to the northern limit of the Mojave Desert ecosystem and is also shown by the millipede Piedolus utus Chamberlin. (Spirobolida: Atopetholidae) and the centipede Theatops posticus (Say) (Scolopendromorpha: Cryptopidae). Tylobolus fredericksoni Causey, ostensibly from Douglas County, Kansas, is designated "nomen dubium" and disregarded pending collection of fresh material; Narceus gordanus (Chamberlin) is deleted from South Carolina and Tennessee. Tyobolus uncigerus (Wood) occurs north of the Columbia …


Contrasting Movement And Activity Of Large Brown Trout And Rainbow Trout In Silver Creek, Idaho, Michael K. Young, Richard A. Wilkison, J. M. Phelps Iii, J. S. Griffith Jul 1997

Contrasting Movement And Activity Of Large Brown Trout And Rainbow Trout In Silver Creek, Idaho, Michael K. Young, Richard A. Wilkison, J. M. Phelps Iii, J. S. Griffith

Great Basin Naturalist

Recent radiotelemetry studies demonstrated that stream-dwelling trout are mobile, but few have compared sympatric species. We used radiotelemetry to simultaneously monitor positions of 20 brown trout and 21 rainbow trout from May or June 1994 to February 1995 in Silver Creek, a small spring-fed stream in south central Idaho. Our biweekly observations from May to September indicated that rainbow trout had larger home ranges (medians, 606 m v. 131 m) and moved greater distances (medians, 1109 m v. 208 m) than brown trout. Furthermore, rainbow trout used more positions than brown trout (means, 7 v. 3) over this interval. Hourly …


Zoogeographic Affinities Of The Stoneflies (Plecoptera) Of The Raft River Mountains, Utah, Richard M. Houseman, Richard W. Baumann Jul 1997

Zoogeographic Affinities Of The Stoneflies (Plecoptera) Of The Raft River Mountains, Utah, Richard M. Houseman, Richard W. Baumann

Great Basin Naturalist

We examined faunal affinities of the Raft River Mountains using stoneflies (Plecoptera) as indicators. This island-like mountain range is isolated from other major mountain ranges in the Intermountain West by low-elevation, arid regions. Thirty-seven species were recorded from collections from 19 sites in the Raft River Mountains. Cluster analysis demonstrated the Raft River Mountain stonefly assemblage to be most similar to faunas of the Sawtooth and Wasatch mountains, and quite different from that of the Sierra Nevada. An analysis of the distribution patterns of each species, on a family-by-family basis, showed that the Raft River Mountains fauna consists mostly of …

The moss species Pseudocrossidium obtusulum (Lindb.) Crum & Anderson is reported for the state of Montana. Recent systematics of the genus Pseudocrossidium in North America is discussed.


Grand Canonical Monte Carlo And Modified Singlet Integral Equations For The Density Profile Of A Yukawa Fluid Near A Planar Wall, Douglas Henderson, Wilmer Olivares-Rivas, Leo Degreve, Jacqueline Quintana May 1997

Grand Canonical Monte Carlo And Modified Singlet Integral Equations For The Density Profile Of A Yukawa Fluid Near A Planar Wall, Douglas Henderson, Wilmer Olivares-Rivas, Leo Degreve, Jacqueline Quintana

Faculty Publications

Results for the density profile for Yukawa molecules near a hard wall and an exponential attractive wall are presented for Grand Canonical Monte Carlo (GCMC) simulations, for the singlet hypernetted chain (HNC) integral equation and for a modified version of the Lovett–Mou–Buff–Wertheim (LMBW-1) which uses the exact contact value theorem. The results of the standard singlet HNC are quite poor. If the LMBW equation is modified (but still using the bulk direct correlation function) the results at high temperature become reasonable. However, the results at low temperatures, close to the bulk coexistence curve, are only a partial improvement. The contact …


Freshwater Sponges (Porifera: Spongillidae) Of Western Montana, Susan H. Barton, John S. Addis May 1997

Freshwater Sponges (Porifera: Spongillidae) Of Western Montana, Susan H. Barton, John S. Addis

Great Basin Naturalist

Between May 1992 and April 1996, freshwater sponges (Porifera: Spongillidae) were collected at 24 sites, distributed among 6 sub-major drainage basins in western Montana, to determine the species present. Water samples also were analyzed from 16 of these sites and from 9 sites at which no sponges were detected to characterize sponge habitats chemically. Three species of sponges were identified: Ephydatia muelleri (Em), Eunapius fragilis (Ef), and Spongilla lacustris (Sl). A 4th type of specimen was present at 2 sites but could not be identified because of the absence of gemmules and gemmoscleres. At 46% of the sites containing sponges, …


Boggy Meadows, Livestock Grazing, And Interspecific Interactions: Influences On The Insular Distribution Of Montane Lincoln's Sparrows (Melospiza Lincolnii Alticola), Carla Cicero May 1997

Boggy Meadows, Livestock Grazing, And Interspecific Interactions: Influences On The Insular Distribution Of Montane Lincoln's Sparrows (Melospiza Lincolnii Alticola), Carla Cicero

Great Basin Naturalist

I surveyed 34 meadows in California and Oregon to count Lincoln's Sparrows (Melospiza lincolnii alticola) and to identify habitat features that might influence their local, insular occurrence. Lincoln's Sparrows were most common in wet meadows with little damage by grazing. Singing males were concentrated in flooded or boggy areas near meadow edges, where pines (Pinus sp.) provided elevated perches for singing and vigilance. Patches of willows (Salix sp.) were often present nearby. Numbers of male Lincoln's Sparrows were strongly and negatively correlated with abundance of sympatric Song Sparrows (M. melodia fisherella). Lincoln's Sparrows breeding …


Classification And Ordination Of Coleogyne Communities In Southern Nevada, Simon A. Lei, Lawrence R. Walker May 1997

Classification And Ordination Of Coleogyne Communities In Southern Nevada, Simon A. Lei, Lawrence R. Walker

Great Basin Naturalist

Woody plant community composition was analyzed throughout the range of Coleogyne ramosissima in the Spring and Sheep Mountain ranges of southern Nevada. The lower Coleogyne elevational boundary was analyzed in detail in Lucky Strike Canyon, on the eastern edge of the Spring Mountains. TWINSPAN (2-way indicator species analysis) identified 4 primary species and stand groups from the 2 mountain ranges (extensive survey). Analysis of DECORANA (detrended correspondence analysis) results indicated that elevation and soil depth were the environmental factors most significantly associated with distribution of species and stand groups in the extensive survey. Elevation was the only significant physical factor …


Variation In Germination Response To Temperature And Water Availability In Blackbrush (Coleogyne Ramosissima) And Its Ecological Significance, Simon A. Lei May 1997

Variation In Germination Response To Temperature And Water Availability In Blackbrush (Coleogyne Ramosissima) And Its Ecological Significance, Simon A. Lei

Great Basin Naturalist

Blackbrush (Coleogyne ramosissima Torr.) is a dominant desert shrub in a distinct mid-elevational vegetation belt between creosote bush–bursage (Larrea tridentata–Ambrosia dumosa) shrubland below and big sagebrush–pinyon pine–Utah juniper (Artemisia tridentata–Pinus monophylla–Juniperus osteosperma) woodland above in the Mojave Desert. Seed germination patterns of blackbrush seeds collected from 2 elevations (1200 and 1550 m) in 5 mountain ranges within the blackbrush shrublands were investigated. Morphological features of blackbrush seeds, including weight, length, and width, were not significantly different (P > 0.05) among elevations and mountain ranges in the Mojave Desert. Germination of blackbrush seeds was optimal when …

Density, Distribution, And Habitat Of Flammulated Owls In Idaho, Craig Groves, Terry Frederick, Glenn Frederick, Eric Atkinson, Melonie Atkinson, Jay Shepherd, Gregg Servheen May 1997

Density, Distribution, And Habitat Of Flammulated Owls In Idaho, Craig Groves, Terry Frederick, Glenn Frederick, Eric Atkinson, Melonie Atkinson, Jay Shepherd, Gregg Servheen

Great Basin Naturalist

From 1990 to 1992 we surveyed for Flammulated Owls (Otus flammeolus) in 3 areas in Idaho: Salmon National Forest (SNF), Payette National Forest and adjacent Hells Canyon National Recreation Area (PNF-HCNRA), and Nez Perce National Forest (NPNF). We also collected and summarized information on all historic and modern records of Flammulated Owls in Idaho. Flammulated Owls were detected on 65% of 68 routes (2–16 km in length) surveyed at densities ranging from 0.04 to 1.25 singing males/40 ha. Owls were detected on survey routes as early as 10 May and as late as 23 July. Mean percent canopy …


Den And Relocation Site Characteristics And Home Ranges Of Peromyscus Truei In The White Mountains Of California, Linnea S. Hall, Michael L. Morrison May 1997

Den And Relocation Site Characteristics And Home Ranges Of Peromyscus Truei In The White Mountains Of California, Linnea S. Hall, Michael L. Morrison

Great Basin Naturalist

We used radio telemetry to describe nighttime movements and daytime den sites of pinyon mice (Peromyscus truei) in the White Mountains of California, 1991–1993. Characteristics of nighttime relocations and den sites for mice concurred with previously reported habitat-use information for the species and supported the claim that pinyon mice use multiple daytime sites. However, males and females were associated with different habitat characteristics at den sites, indicating differential microhabitat selection by the sexes, perhaps related to reproductive constraints on females. Pinyon mice also exhibited high variability in den site habitat use in the summer, but low variability in …


Late Fall And Early Spring Bird Observations For Mulegé, Baja California Sur, Mexico, Robert C. Whitmore, R. Craig Whitmore May 1997

Late Fall And Early Spring Bird Observations For Mulegé, Baja California Sur, Mexico, Robert C. Whitmore, R. Craig Whitmore

Great Basin Naturalist

Observational data from spring and fall 1996 and spring 1997 for the region near Mulegé, Baja California Sur, Mexico, are summarized in tabular form. In addition, new or noteworthy data for 17 species are annotated to provide clarification of previously published records. A uniquely plumaged bird, too far south for a female American Robin (Turdus migratorius) in basic plumage and too far north for the endemic "San Lucas" Robin (Turdus migratorius confinis) and intermediate in coloration between the two, was recorded. Range expansions are documented for several species including the European Starling (Sturnus vulgaris), …


Interannual Abundance Of Nonnative Fathead Minnows (Pimephales Promelas) In Upper Klamath Lake, Oregon, David C. Simon, Douglas F. Markle May 1997

Interannual Abundance Of Nonnative Fathead Minnows (Pimephales Promelas) In Upper Klamath Lake, Oregon, David C. Simon, Douglas F. Markle

Great Basin Naturalist

Since its introduction about 20 yr ago, fathead minnow (Pimephales promelas) has become very abundant in Upper Klamath Lake, Oregon. In 1991 mean beach seine catch per unit effort (CPUE) was 214, compared to 25 for native blue chub (Gila coerulea), the next most abundant species. In 45 trap-net samples collected in 1992, fathead minnow constituted 59% of the fishes caught in Agency Lake subbasin, 27% in Upper Klamath Lake, and 17% in tributary inflow habitats. From 1991 to 1995 fathead minnow declined and the abundance of some native fishes increased. Introduction to Klamath Basin was …


Biotic And Abiotic Factors Influencing The Distribution Of Coleogyne Communities In Southern Nevada, Simon A. Lei, Lawrence R. Walker May 1997

Biotic And Abiotic Factors Influencing The Distribution Of Coleogyne Communities In Southern Nevada, Simon A. Lei, Lawrence R. Walker

Great Basin Naturalist

Coleogyne ramosissima is a desert shrub that forms a nearly monospecific shrubland and occupies a well-defined elevational band between approximately 1050 and 2150 m on mountain ranges in southern Nevada. The Coleogyne shrubland shares relatively broad upper and lower ecotones with Pinus-Juniperus and Larrea-Ambrosia plant communites, respectively. We characterized the extent that environmental factors correlate with Coleogyne density and examined variation in biotic and abiotic factors along the lower elevational boundary of Coleogyne in Lucky Strike Canyon near Las Vegas, Nevada. Coleogyne density was positively correlated with gravimetric soil moisture, soil organic matter, Coleogyne water potential, Coleogyne stem and leaf …

Diplostomiasis In Native And Introduced Fishes From Yellowstone Lake, Wyoming, Victor H. Inchausty, Michael Foutz, Richard A. Heckmann, Claudete Ruas, Paulo Ruas

Great Basin Naturalist

Totals of 101 native Yellowstone cutthroat (Oncorhynchus clarki bouvieri), 27 introduced lake trout (Salvelinus namaycush), and 40 introduced longnose sucker (Catostomus catostomus) from Yellowstone Lake, Wyoming, USA, were examined for eye flukes. Metacercariae of the trematode fluke Diplostomum were in vitreous humor and/or lens of 94% of Yellowstone cutthroat trout, 92% of lake trout, and 78% of longnose sucker. Longnose sucker had 7% prevalence of infection in both lens and vitreous humor of metacercariae, while Yellowstone cutthroat trout had 3% and lake trout 8%. Diplostomum spathaceum was in lens tissue of 5% of infected …

Human Trampling Effects On Regeneration And Age Structures Of Pinus Edulis And Juniperus Monosperma, Alex S. Tonnesen, James J. Ebersole Mar 1997

Human Trampling Effects On Regeneration And Age Structures Of Pinus Edulis And Juniperus Monosperma, Alex S. Tonnesen, James J. Ebersole

Great Basin Naturalist

We examined effects of human foot traffic on age structures and densities of seedlings and saplings of Pinus edulis (Colorado pinyon) and Junisperus monosperma (one-seed juniper) in a heavily used urban park, Garden of the Gods, Colorado. Age structures show no stand-destroying disturbances, but they do contain small peaks 85–95 yr ago (minimum age), which have been interpreted as responses to heavy grazing. For Pinus edulis reverse J-shaped age structures indicate a strongly reproducing population, while flat age structures of J. monosperma show low present reproduction. Young trees showed strong preferences for establishing under existing trees and shrubs and not …
