Red Butte Canyon is a protected, near pristine canyon entering Salt Lake Valley, Utah. It contains a well-developed riparian zone and a perennial stream; hillside vegetation ranges from grasslands on the lower limits to Douglas-fir and aspen stands at the upper elevations. In this paper we describe the history of human impact, natural history aspects of climate, geology, and ecology, and faunal and floral information for key species in the canyon. The role and importance of Research Natural Areas is discussed, particularly with respect to the need to protect Red Butte Canyon—one of the few remaining undisturbed riparian ecosystems in …

We have adapted techniques developed for the extraction of DNA from formalin-fixed, paraffin-imbedded human tissues for use on preserved fish tissues. DNA was successfully extracted and the d-loop region of mitochondrial DNA was amplified with the polymerase chain reaction (PCR). The sequences of the amplified DNA from preserved and modern samples were identical. These techniques were also applied to fin tissue treated with a variety of preservatives. Extraction of DNA from ethyl alcohol and air-dried fin tissues gave yields equivalent to those from frozen tissues. Extraction of DNA from preserved museum specimens of rare or extinct taxa could significantly increase …

Radio Transmitter Attachment For Chukars, Bartel T. Slaugh, Jerran T. Flinders, Jay A. Roberson, M. Ray Olson, N. Paul Johnston
Radio Transmitter Attachment For Chukars, Bartel T. Slaugh, Jerran T. Flinders, Jay A. Roberson, M. Ray Olson, N. Paul Johnston
Great Basin Naturalist
Thirty-seven Chukars (Alectoris chukar), fitted with conventional poncho-type radio transmitters, were released on Antelope Island in Utah's Great Salt Lake. Twenty-seven removed their radios, averaging three days after release. The remaining 10 died from predation (average 15 days). Twenty-two Chukars with pleated and six with harness ponchos were then released. Five of the pleated ponchos were removed (average four days), and 17 resulted in mortality (average two days). All six harness poncho-equipped birds were dead the following day. A consequential laboratory study comparing various attachment methods (conventional, pleated, harness, and "irreversible" flange poncho vs. bellystrap and wingstrap backpack) …
Winter Habitats And Foods Of Blue Grouse In The Sheeprock Mountains, Utah, Peter J. Perkins, Frederick G. Lindzey, Jay A. Roberson, Gregory Mcdaniel, Randy Berger
Winter Habitats And Foods Of Blue Grouse In The Sheeprock Mountains, Utah, Peter J. Perkins, Frederick G. Lindzey, Jay A. Roberson, Gregory Mcdaniel, Randy Berger
Great Basin Naturalist
Winter habitat use and food habits of Blue Grouse (Dendragapus obscurus) were studied in an isolated Utah desert mountain range that contained little typical Douglas-fir (Pseudotsuga menziesii) winter habitat. Habitat use was concentrated in the Douglas-fir and pinyon (Pinus edulis)–juniper (Juniperus spp.) habitat. Douglas-fir and pinyon pine were the most consumed foods. Other foods that represented >15% of the composition of an individual fecal sample were limber pine (Pinus flexilis), mahogany (Cercocarpus ledifoliu), juniper, and an Anteunaria–Cirsium type. The breadth in winter diet indicates that Blue Grouse may …
Changes In Mule Deer Size In Utah, Dennis D. Austin, Robert A. Riggs, Philip J. Urness, David L. Turner, John F. Kimball
Changes In Mule Deer Size In Utah, Dennis D. Austin, Robert A. Riggs, Philip J. Urness, David L. Turner, John F. Kimball
Great Basin Naturalist
Trends in age-specific, eviscerated carcass weights were determined for hunter-harvested yearling and two-year-old buck mule deer. Carcass weights declined over an 11-year period from two areas of similar management, but with independenly collected data sets. Carcass weights also declined between the opening and second weekends of the hunt. Management implications are discussed.
Computer Analysis Of Cross Sections Of Leaves Of Chrysothamnus Taxa And Their Relation To Environmental Conditions, J. Huang, W. M. Hess, D. J. Weber, E. D. Mcarthur, S. E. Meyer, R. Seegmiller
Computer Analysis Of Cross Sections Of Leaves Of Chrysothamnus Taxa And Their Relation To Environmental Conditions, J. Huang, W. M. Hess, D. J. Weber, E. D. Mcarthur, S. E. Meyer, R. Seegmiller
Great Basin Naturalist
Thirty-eight accessions of 20 taxa (species and subspecies) of Chrysothamnus from a range of environments were grown in a uniform garden. During mid-June, terminal and lateral leaves were removed, fixed, and processed for light-microscopy studies. Area and perimeter measurements of ink tracings of midleaf vein cross sections were measured using computer-scan techniques. Leaf area and perimeter were compared with vein perimeter and area measurements. Area and perimeter of these Chrysothamnus leaves varied in response to the environment at the collection location. Plants native to hot, dry conditions had small, thick leaves, whereas plants native to cooler, more mesic conditions had …

Distribution Of Vertebrates Of The Bighorn Canyon National Recreation Area, Stanley H. Anderson, Wayne A. Hubert, Craig Patterson, Alan J. Redder, David Duvall
Great Basin Naturalist
During a survey of the vertebrates in the Bighorn Canyon National Recreation Area, 46 mammal, 210 bird, 9 reptile, 5 amphibian, and 28 fish species were found. Habitat structure and moisture were two environmental variables associated with species numbers across this 1,820-ha area. Eight distinct habitats were evaluated. In coniferous forests, 27% of the birds and 54% of the mammals were observed. Sagebrush/grasslands and upland shrublands were very arid and had relatively few vertebrates. Five introduced game birds occurred in sagebrush habitat. Riparian and wetland habitats had the largest number of unique vertebrates, 38 and 77 respectively. The establishment of …
