Burrow Plugging By Prairie Dogs In Response To Siberian Polecats, Stephen J. Martin, Max H. Schroeder, Howard Tietjen Jul 1984

Burrow Plugging By Prairie Dogs In Response To Siberian Polecats, Stephen J. Martin, Max H. Schroeder, Howard Tietjen

Great Basin Naturalist

Siberian polecats (Mustela eversmanni) were placed in white-tailed prairie dog (Cynomys leucurus) and black-tailed prairie dog (C. ludovicianus) burrows to simulate a black-footed ferret (M. nigripes) visit. Both prairie dog species plugged burrows "visited" by polecats. White-tailed and black-tailed prairie dogs plugged 2 of 6 and 3 of 6 test burrows, respectively.

Chrysothamnus Nauseosus Ssp. Uintahensis: A Stabilized Hybrid, Loran C. Anderson Jul 1984

Chrysothamnus Nauseosus Ssp. Uintahensis: A Stabilized Hybrid, Loran C. Anderson

Great Basin Naturalist

Chrysothamnus nauseosus ssp. uintahensis (Asteraceae) is formally described and illustrated. The new subspecies represents stabilized hybrids that most probably have C. nauseosus ssp. hololeucus × C. parryi ssp. attenuatus ancestry. Morphological and anatomical comparisons are made among the putatively related taxa.

Differential Winter Mortality Between Male And Female Mule Deer Fawns In Utah, Jordan C. Pederson Jul 1984

Differential Winter Mortality Between Male And Female Mule Deer Fawns In Utah, Jordan C. Pederson

Great Basin Naturalist

During the winters of 1980–1984 winter mortality of mule deer fawns in central Utah was assessed. It was determined that the winter mortality ratio for female fawns as compared to males was 156:100. This mortality factor should be taken into consideration by game and range managers when determining harvest recommendations.

Transverse Pattern Of Vegetation On Avalanche Paths In The Northern Rocky Mountains, Montana, George P. Malanson, David R. Butler Jul 1984

Transverse Pattern Of Vegetation On Avalanche Paths In The Northern Rocky Mountains, Montana, George P. Malanson, David R. Butler

Great Basin Naturalist

The pattern of vegetation on avalanche paths has usually been ascribed to the damage done by snowslides. In the northern Rocky Mountains the pattern of herbs, shrubs, and small trees appears to be more complex than could be accounted for by avalanche magnitude and frequency. The vegetation on one path in Montana illustrates that the topography of the path is a factor in the distribution of species. Three zones exist across avalanche paths: an inner zone of herbs and suffrutescent shrubs occupying a ravine, which is snow covered longer than elsewhere; flanking zones of dense shrubs and trees with flexible …

Mule Deer Passage Beneath An Overland Coal Conveyer, Charles L. Greenwood, Larry B. Dalton Jul 1984

Mule Deer Passage Beneath An Overland Coal Conveyer, Charles L. Greenwood, Larry B. Dalton

Great Basin Naturalist

Presently, information pertaining to migration and daily movement patterns of big game in relation to overland conveyors or large diameter pipelines is sparse. A literature review showed that moose (Alces alces), caribou (Rangifer tarandus granti), reindeer, and dall sheep (Ovis dalli dalli) will pass beneath or over large diameter pipeline systems. But no information was found relative to big game crossing coal conveyor systems. Mule deer (Odocoileus hemionus) passage beneath an overland coal conveyor in Carbon County, Utah, was studied during spring 1981. Deer avoided crossing at underpass opportunities where the clearance …

Notes On The White-Tailed Antelope Squirrel, Ammospermophilus Leucurus, And The Pinyon Mouse, Peromyscus Truei, In North Central Nevada, Michael J. O'Farrell, William A. Clark Jul 1984

Notes On The White-Tailed Antelope Squirrel, Ammospermophilus Leucurus, And The Pinyon Mouse, Peromyscus Truei, In North Central Nevada, Michael J. O'Farrell, William A. Clark

Great Basin Naturalist

A four-season live trapping study in the Whirlwind Valley, on the Lander and Eureka county lines near the Humboldt River, yielded two species previously unrecorded from both counties, Ammospermophilus leucurus and Peromyscus truei. Both records represent minimal airline range extension of 113 and 105 km. It is suggested that the distribution of A. leucurus may include the entire northeastern quadrant of Nevada. The occurrence of P. truei in sagebrush habitat 21 km from the nearest pinyon woodland is unusual and suggests that this species may occur patchily distributed throughout the lower elevation ranges in the northern portion of the state.

Genetics Of Hybridization Between The Pocket Gophers Thomomys Bottae And Thomomys Townsendii In Northeastern California, James L. Patton, Margaret F. Smith, Roger D. Price, Ronald A. Hellenthal Jul 1984

Genetics Of Hybridization Between The Pocket Gophers Thomomys Bottae And Thomomys Townsendii In Northeastern California, James L. Patton, Margaret F. Smith, Roger D. Price, Ronald A. Hellenthal

Great Basin Naturalist

Hybridization between the pocket gophers Thomomys bottae and T. townsendii at Gold Run Creek in Honey Lake Valley, Lassen County, California, is examined by electromorphic and morphologic characters and by the distribution of ectoparasitic mallophagan lice. Hybrid formation is minimal (about 12% of the total sample of 104 individuals examined), but both F1 hybrids and a few presumptive backcross individuals are apparent. Nevertheless, no evidence of genic introgression based on five diagnostic allozyme loci is present in parental populations of either taxon within a mile of the hybrid zone. Similarly, louse species unique to each parental gopher host do …

On Cowania And Its Intergeneric Hybrids In Arizona, Marc A. Baker, Donald J. Pinkava, Bruce Parfitt, Timothy Righetti Jul 1984

On Cowania And Its Intergeneric Hybrids In Arizona, Marc A. Baker, Donald J. Pinkava, Bruce Parfitt, Timothy Righetti

Great Basin Naturalist

The putative intergeneric hybridization between Stansbury Cliffrose (Cowania) and Apache Plume (Fallugia) is found to be undocumented. Chromosome counts support reported base numbers for Cowania and Fallugia to be n = 9 and n = 14 respectively.

Effects Of 2,4-D On A Populus Tremuloides Community In The Western United States—22 Years After Treatment, Dale L. Bartos, James E. Lester Jul 1984

Effects Of 2,4-D On A Populus Tremuloides Community In The Western United States—22 Years After Treatment, Dale L. Bartos, James E. Lester

Great Basin Naturalist

Quaking aspen (Populus tremuloides Michx.) stands were accidentally sprayed with 2,4-D in a sagebrush control program in western Wyoming in 1958. We visited the site during the summer of 1981 to evaluate the long-term effect on the aspen trees and the associated vegetation. Initially, some observers believed that the aspen had been "destroyed." Subsequent data indicate just the opposite—aspen stocking appeared to have been improved by the treatment. On two of the sampled clones, 22 years after spraying, there were approximately 17,000 more suckers/ha on the sprayed than on the unsprayed plots. These are adequate numbers to restock the …

Cranial Measurements Of The Columbian Ground Squirrel (Spermophilus Columbianus Columbianus), With Special Reference To Subspecies Taxonomy And Juvenile Skull Development, Charles L. Elliott, Jerran T. Flinders Jul 1984

Cranial Measurements Of The Columbian Ground Squirrel (Spermophilus Columbianus Columbianus), With Special Reference To Subspecies Taxonomy And Juvenile Skull Development, Charles L. Elliott, Jerran T. Flinders

Great Basin Naturalist

The Columbian ground squirrel (Spermophilus columbianus (Ord)) is represented by two recognized subspecies, S. c. columbianus (Ord) and S. c. ruficaudus (A. H. Howell), that occupy allopatric but adjacent geographical areas in Washington, Oregon, and Idaho. Since numerical cranial characteristics of these subspecies have not been documented, we measured 8 cranial characteristics on 94 adult and 32 juvenile Columbian ground squirrels in an area considered to be occupied by S. c. columbianus. Body weights and standard body measurements were recorded for adults and juveniles. The study area included portions of the River of No Return Wilderness Area in central …
