Ecological Relationships Of Curlleaf Mountain-Mahogany (Cercocarpus Ledifolius Nutt.) Communities In Utah And Implications For Management, James N. Davis, Jack D. Brotherson
Ecological Relationships Of Curlleaf Mountain-Mahogany (Cercocarpus Ledifolius Nutt.) Communities In Utah And Implications For Management, James N. Davis, Jack D. Brotherson
Great Basin Naturalist
Curlleaf mountain-mahogany is a widely distributed shrubby tree of western North America. Well-developed stands are most often found on warm, dry, rocky ridges and slopes at high elevations on mostly southern exposures. It can, however, be found onall exposures. The species appears to be indifferent to substrate with soils which are invariably shallow and of low fertility. However, the nitrogen-fixing root nodules help overcome soil deficiencies. This highly palatable species is preferred by mountain sheep, mountain goats, deer, and elk. Its nutritive value (about 12% protein) and digestibility ratings (around 50%) in the winter are high when compared with most …

Mourning Dove Use Of Man-Made Ponds In A Cold-Desert Ecosystem In Idaho, Frank P. Howe, Lester D. Flake
Mourning Dove Use Of Man-Made Ponds In A Cold-Desert Ecosystem In Idaho, Frank P. Howe, Lester D. Flake
Great Basin Naturalist
Mourning Doves (Zenaida macroura) in a cold-desert ecosystem used man-made ponds for watering, feeding, gritting, loafing, and courting. Diurnal pond use by doves peaked in the morning and evening. Monthly dove use of ponds fluctuated slightly during the summers of 1984 and 1985. Pond size, pH, and shoreline characteristics had little association with the intensity of pond use by doves; but geographic isolation of ponds was weakly associated with pond-use intensity. The number of doves present at the beginning of the one-hour period was a poor indicator of the number of arrivals during that period. We conclude that …

Physiographic Characteristics Of Peregrine Falcon Nesting Habitat Along The Colorado River System In Utah, Brandon L. Grebence, Clayton M. White
Physiographic Characteristics Of Peregrine Falcon Nesting Habitat Along The Colorado River System In Utah, Brandon L. Grebence, Clayton M. White
Great Basin Naturalist
Portions of the Colorado, Dolores, Green, and San Rafael rivers in Utah were surveyed for the breeding Peregrine Falcon (Falco peregrinus anatum) from 1986 to 1988. Eleven physical variables were measured at nest cliffs (N = 22) and nonnest cliffs (N = 22) to discern descriptors of cliff choice and subsequent occupancy by breeding peregrines in unexplored habitat within the Colorado River and its tributaries. Ratio scale measurements were subjected to discriminant function analysis or the Mann-Whitney test to determine significant differences between cliff types. At nest cliffs, Rayleigh's and Kuiper's tests were applied to compass directions to …
Influence Of Experimental Habitat Manipulations On A Desert Rodent Population In Southern Utah, Jiping Zou, Jerran T. Flinders, Hal L. Black, Steven G. Whisenant
Influence Of Experimental Habitat Manipulations On A Desert Rodent Population In Southern Utah, Jiping Zou, Jerran T. Flinders, Hal L. Black, Steven G. Whisenant
Great Basin Naturalist
This paper addresses how habitat manipulations in a black sagebrush (Artemisia nova)–dominated area, John's Valley of southern Utah, affected resident desert rodent populations. Rodents studied included the deer mouse (Peromyscus maniculatus), Great Basin pocket mouse (Perognathus parvus), sagebrush vole (Lagurus curtatus), Ord's kangaroo rat (Dipodomys ordii), and least chipmunk (Eutamias minimus). The experimental design involved analyses of treatment and control (nontreatment) plots rather than pre- and posttreatment of all plots. Habitat manipulations emphasized cutting of shrubs (rotobeating), treatment of plants with a herbicide (2,4-D), and reseeding with a …

Co-Occupancy Of A Den By A Pair Of Great Basin Black Bears, John M. Goodrich, San J. Stiver
Great Basin Naturalist
An adult male and an adult female black bear (Ursus americanus) were found in the same den in the Carson Range of the Sierra Nevada in Nevada. Co-occupancy of dens is very rare, and such behavior has never been previously reported for adult bears of opposite sex.
Foods And Feeding Periodicity Of The White River Springfish, Crenichthys Baileyi, Gene R. Wilde
Foods And Feeding Periodicity Of The White River Springfish, Crenichthys Baileyi, Gene R. Wilde
Great Basin Naturalist
White River springfish collected in August and December 1966 from Hot Creek Spring, Nevada, fed primarily on amphipods, ostracods, plant fragments, and detritus. Compostition of the diet was similar in both months. However, amphipods were the most important food in August, while in December amphipods, ostacods, plant fragments, and detritus were of approximately equal importance. Comparison of diel feeding periodicity and activity patterns suggests that most of the daily activity of White River springfish is related to feeding.
Interactions Among Squirrels, Mycorrhizal Fungi, And Coniferous Forests In Oregon, Chris Maser, Zane Maser
Interactions Among Squirrels, Mycorrhizal Fungi, And Coniferous Forests In Oregon, Chris Maser, Zane Maser
Great Basin Naturalist
We examined the mycophagy (ingestion of fungi) of squirrels of five genera and eight species in the coniferous forests of Oregon. Data from 644 dietary samples demonstrated that squirrels of all eight species are mycophagous and eat the belowground fruiting bodies of at least 26 genera of mycorrhizal fungi. Four species are primarily arboreal and active throughout the year; the other four are primarily terrestrial and hibernate during winter. Of the squirrels examined, only the northern flying squirrel (Glaucomys sabrinus [Shaw]) is nocturnal and almost exclusively a fungivore. The flying squirrel is used to illustrate the dynamics of all …

Mycophagy Of Red-Backed Voles, Clethrionomys Californicus And C. Gapperi, Chris Maser, Zane Maser
Mycophagy Of Red-Backed Voles, Clethrionomys Californicus And C. Gapperi, Chris Maser, Zane Maser
Great Basin Naturalist
We examined stomach contents of 426 Clethrionomys, 217 C. californicus from western Oregon and 209 C. gapperi from widely scattered areas across North America. Clethrionomys californicus consumed fungi of 28 genera. Clethrionomys gapperi from the Rocky Mountains westward consumed fungi of 23 genera, whereas C. gapperi east of the Rocky Mountains consumed fungi of 7 genera. This study supports the conclusions of an earlier study, limited to Oregon and Washington, that food habits of C. californicus and C. gapperi are more closely related to habitat than to species or subspecies of vole.
A Review Of Flea Collection Records From Onychomys Leucogaster With Observations On The Role Of Grasshopper Mice In The Epizoology Of Wild Rodent Plaque, Rex E. Thomas
Great Basin Naturalist
Published records of fleas collected from the northern grasshopper mouse, Onychomys leucogaster, indicate that these mice have a great deal of intimate environmental contact with other rodents or their burrows. Fifty-seven species of fleas have been collected from the omnivorous grasshopper mouse. The range of this mouse overlaps much of the distribution of plague, Yersinia pestis, in the western United States; and nearly one-half of the flea species collected from O. leucogaster are known to be of importance in the epizoology of plague. This article discusses the importance of the association of fleas with a hospitable secondary host …

Observations made herein indicate that individual variation in maternal behavior existis in this species.
Annotated Inventory Of Invertebrate Populations Of An Alpine Lake And Stream Chain In Colorado, John H. Bushnell, Susan Q. Foster, Bruce M. Wahle
Annotated Inventory Of Invertebrate Populations Of An Alpine Lake And Stream Chain In Colorado, John H. Bushnell, Susan Q. Foster, Bruce M. Wahle
Great Basin Naturalist
Benthic macroinvertebrates were collected during the ice-free season (1 July–20 October) over a five-year period from a chain of alpine lakes and intervening streams in the Green Lakes Valley (3,347–3,615 m) in Boulder County, Colorado. A list of taxa was developed for 1981 and 1982, with taxonomic additions for 1983–1985 and comments on community structure, seasonal and elevational changes in species abundance, and noteworthy occurrences. A total of 111 taxa was collected, of which 84% occurred in streams, 58% being exclusively lotic. Dipterans composed 73–81% of total abundance in streams. The littoral benthic zone of lakes was predominantly trichopterans and …
Burrows Of The Sagebrush Vole (Lemmiscus Curtatus) In Southeastern Idaho, Tim R. Mullican, Barry L. Keller
Burrows Of The Sagebrush Vole (Lemmiscus Curtatus) In Southeastern Idaho, Tim R. Mullican, Barry L. Keller
Great Basin Naturalist
Burrows of the sagebrush vole (Lemmiscus curtatus) were analyzed by injecting them with expanding polyurethane foam. Average mean depth ± 1 SE of four burrows was 12.5 ± 2.6 cm. Tunnels were wider than high and flat on the bottom. Three of four burrows were nearly linear, with an average of five entrances. Burrows usually contained one nest made of Artemisia tridentata bark. No middens or communal nests were found. The burrow structure in sagebrush habitat suggests that sagebrush voles occur singly or in pairs rather than in colonies.
Ecological Comparison Of Sympatric Populations Of Sand Lizards (Cophosaurus Texanus And Callisaurus Draconoides), Donald D. Smith, Philip A. Medica, Sherburn R. Sanborn
Ecological Comparison Of Sympatric Populations Of Sand Lizards (Cophosaurus Texanus And Callisaurus Draconoides), Donald D. Smith, Philip A. Medica, Sherburn R. Sanborn
Great Basin Naturalist
Sympatric populations of Cophosaurus texanus and Callisaurus draconoides were periodically sampled from March 1973 through April 1974 at Burro Creek, Mohave County, Arizona. Callisaurus were also sampled at Rock Valley, Nye County, Nevada. Sex ratios were skewed in favor of males in the adult Cophosaurus but were equal in both adult populations of Callisaurus. Both species became sexually mature as yearlings. Mean clutch sizes were 3.55 (±0.83) for Cophosaurus, and 4.25 (±1.08) and 5.07 (±1.33) for Callisaurus at Burro Creek and Rock Valley respectively. Evidence of multiple clutches was exhibited by both species. Egg weight/body weight ratios for both species …
Habitat And Community Relationships Of Cliffrose (Cowania Mexicana Var. Stansburiana) In Central Utah, K. P. Price, J. D. Brotherson
Habitat And Community Relationships Of Cliffrose (Cowania Mexicana Var. Stansburiana) In Central Utah, K. P. Price, J. D. Brotherson
Great Basin Naturalist
Cliffrose (Cowania mexicana var. stansburiana [Torr.] Jepson) community measurements were taken in central Utah. Data revealed a high between-site similarity of 78.5%. Soil analysis for sites showed most macronutrients, and some micronutrients, relatively low. Cover of cliffrose was found to increase with increases in soil magnesium (p ≤ 0.01). Plants growing on the sites have adapted life cycles to exploit moisture and nutrients during seasons of maximum availability. Prevalent species in the community were cheatgrass (Bromus tectorum), cliffrose, madwort (Alyssum alyssoides), and bluebunch wheatgrass (Agropyron spicatum). Annual grasses were the most important life …
Size, Structure, And Habitat Characteristics Of Populations Of Braya Humilis Var. Humilis (Brassicaceae): An Alpine Disjunct From Colorado, Elizabeth E. Neely, Alan T. Carpenter
Size, Structure, And Habitat Characteristics Of Populations Of Braya Humilis Var. Humilis (Brassicaceae): An Alpine Disjunct From Colorado, Elizabeth E. Neely, Alan T. Carpenter
Great Basin Naturalist
Size, structure, and habitat characteristics were studied in three populations of Braya humilis var. humilis (C. A. Meyer) Robins, in Gray & Wats. (Brassicaceae), a small, herbaceous perennial of the alpine tundra in central Colorado. There was a significant association between numbers of reproductive, juvenile, and seedling individuals and population location. Plant size within reproductive, juvenile, and seedling size classes varied significantly among three populations. Plots containing Braya had significantly lower total plant cover, a different set of dominant plant species, more rock, bare ground, and less litter than plots without Braya. Braya appears to be restricted to calcareous …

Movements By Small Mammals On A Radioactive Waste Disposal Area In Southeastern Idaho, Craig R. Groves, Barry L. Keller
Movements By Small Mammals On A Radioactive Waste Disposal Area In Southeastern Idaho, Craig R. Groves, Barry L. Keller
Great Basin Naturalist
Average linear movement by populations of Dipodomys ordii, Microtus montanus, Perognathus parvus, and Peromyscus maniculatus was investigated over a 15-month period by live trapping on a low-level, radioactive waste disposal area in Idaho. No significant differences in movement among habitats were observed seasonally, excepting M. montanus in spring. Average linear movements within habitats ranged from 20 to 70 m for all species, but some patterns varied seasonally and among age classes for individual species. Although predation on contaminated small mammals from the disposal area is a vector of radionuclide transport, local movements by these rodents do not appear to be …

Habitat Relationships Of Saltcedar (Tamarix Ramosissima) In Central Utah, Jack D. Brotherson, Von Winkel
Habitat Relationships Of Saltcedar (Tamarix Ramosissima) In Central Utah, Jack D. Brotherson, Von Winkel
Great Basin Naturalist
Nineteen study sites were established in areas infested with saltcedar bordering Utah Lake in central Utah. Saltcedar cover on the sites averaged 57% but varied widely from community to community. Seventeen soil factors were measured relative to the stands studied. Cover of saltcedar was regressed against the different soil factors, but no patterns were detected. Saltcedar functioned equally well at all levels of each gradient studied and appeared able to accommodate wide variations in all factors studied. It is suggested that saltcedar has evolved a general-purpose genotype that contributes to its being a vigorous and troublesome weed. Criteria as to …
