Impacts Of Black-Tailed Prarie Dog Rodenticides On Nontarget Passerines, Anthony D. Apa, Daniel W. Uresk, Raymond L. Linder

Great Basin Naturalist

In 1983 zinc phosphide, strychnine with prebait, and strychnine without prebait were applied to black-tailed prairie dog (Cynomys ludovicianus) colonies in west central South Dakota. Short-term (four days later) and long-term (one year later) impacts of the rodenticides on Horned Larks (Eremophila alpestris) and other granivorous birds inhabiting prairie dog colonies were evaluated. Hrned Larks and 49 other bird species were observed. Immediate impacts reduced Horned Lark relative densities 66% with strychnine only and 55% with prebaited strychnine. Zinc phosphide caused no measurable reduction. Horned Larks showed no long-term direct impacts. Indirect negative impacts occurred through …

Vegetation And Soil Zonation Associated With Juniperus Pinchotii Sudw. Trees, Guy R. Mcpherson, G. Allen Rasmussen, David B. Wester, Robert A. Masters

Great Basin Naturalist

Herbaceous vegetation pattern and soil properties around individual Juniperus pinchotii Sudw. trees were studied on a grazed and a relict grassland in western Texas. Herb standing crop and soil samples were obtained under the canopy, at canopy edge, and beyond the canopy edge of three to five trees on each of four dates. Standing crop was lowest midway between the bole and canopy edge. Soil organic matter was highest under juniper canopies on both sites. Soil pH and P were not related to distance from tree bole on either site. Herbaceous pattern from under the canopy to canopy edge apparently …

Alkaloidal Relationships In The Genus Arctomecon (Papaveraceae) And Herbivory In A. Humilis, Douglas A. Raynie, Deanna R. Nelson, Kimball T. Harper

Great Basin Naturalist

The previously reported alkaloids (including protopines, benzophenanthridines, tetrahydrobenzylisoquinolines, and protoberberines) of the genus Arctomecon (Papaveraceae) are discussed in relation to their distribution in the plant kingdom, in the Papaveraceae, and among the three species of Arctomecon. The biological activity of these alkaloids is discussed, and possible implications for herbivore and plant-insect interactions in A. humilis are presented.

Flower Mites Of Trinidad Ii. The Genus Proctolaelaps (Acari: Ascidae), Barry M. Oconnor, Robert K. Colwell, Shahid Naeem

Great Basin Naturalist

Nine species of mites of the genus Proctolaelaps were collected in flowers or phoretic in the nares of hummingbirds in Trinidad. Previously named species P. kirmsei, P. glaucis, and P. belemensis are redescribed, and six new species are described: P. jurgatus, P. mermillion, P. rabulatus, P. contumex, P. certator, and P. contentiosus. Proctolaelaps belemensis cyanocompsae is raised to specific status. Host plants are given for all species except P. mermillion, which was collected only from a hummingbird host. New World flower-inhabiting Proctolaelaps are grouped into two hypothetically monophyletic lineages, the kirmsei …

Morphological Variability And Cell Wall Composition Of Phaeodactylum Tricornutum (Bacillariophyceae), Jeffrey R. Johansen

Great Basin Naturalist

Five isolates of Phaeodactylum tricornutum Bohlin were examined in light and transmission electron microscopes. Although isolated from widely separated sites including both coastal marine and inland saline habitats, the morphology of the siliceous frustules of all isolates was very constant. The fusiform and triradiate forms, which have been reported as being non-siliceous in the past, were found to have an amorphous particulate nature in TEM. These forms were examined using EDAX SEM elemental analysis and were found to contain silica in their cell walls.

Scanning Electron Microscopic Study Of The Male Genitalia Of The North American Alderfly Genus Sialis (Megaloptera: Sialidae), Michael F. Whiting

Great Basin Naturalist

Scanning electron micrographs are presented for 14 species of the North American alderfly Sialis: americana, arvalis, californica, contigua, cornuta, hamata, iola, joppa, mohri, nevadensis, occidens, rotunda, vagans, and velata. Male genitalic characters are described for use in species identification.

Fishes Of Bly Tunnel, Lassen County, California, Peter B. Moyle, Thomas Kennedy, Derek Kuda, Laurie Martin

Great Basin Naturalist

Leon Bly Tunnel, which connects Eagle Lake to Willow Creek, was investigated to see if the water issuing from the tunnel was lake water or spring water and to check reports of its being inhabited by fish. We found that the water was similar to that of highly alkaline Eagle Lake, despite a block placed in the tunnel in 1986. Five species of fish were found in the tunnel, the same species inhabiting both Willow Creek and Eagle Lake, although the creek was much warmer and less alkaline than the lake. The fish originated from the creek. Fish in the …

Heavy Metal Tolerance Of Inland Saltgrass (Distichlis Spicata), R. A. Prodgers, W. P. Inskeep

Great Basin Naturalist

Inland saltgrass (Distichlis spicata) occurs on at least two metal-contaminated sites in southwestern Montana. As a result of mining, milling, and smelting activities, soils have elevated concentrations of copper, zinc, and manganese. One soil is acidic (upper horizons), slightly saline, and moderately sodic. The other soil is alkaline, nonsaline, and nonsodic. The fact that inland saltgrass grows on these soils and does not accumulate dangerous levels of metals makes it a candidate species for revegetating hardrock mining and other metal-polluted sites.

Habitat Use And Food Selection Of Small Mammals Near A Sagebrush/Crested Wheatgrass Interface In Southeastern Idaho, David K. Koehler, Stanley H. Anderson

Great Basin Naturalist

Habitat use and food selection data were collected for deer mice (Peromyscus maniculatus), montane voles (Microtus montanus), Ord's kangaroo rats (Dipodomys ordii), and Townsend's ground squirrels (Spermophilus townsendii) near a sagebrush (Artemisia tridentata )/crested wheatgrass (Agropyron cristatum) interface in southeastem Idaho. Significantly more captures occurred in the native sagebrush habitat than in areas planted in crested wheatgrass or in disturbed sites. Crested wheatgrass, a prolific seed producer, still accounted for over 30% of the total captures. Montane voles and Townsend's ground squirrels (during periods of aboveground activity) used the …

Habitat Evaluation Procedure For Rocky Mountain Bighorn Sheep In The Intermountain West, Tom S. Smith, Jerran T. Flinders, David S. Winn

Great Basin Naturalist

Several habitat evaluation procedures have been developed for bighorn sheep. However, none of these procedures specifically addresses the Rocky Mountain subspecies nor analyzes both the quantity and quality of potential bighorn habitat with regard to minimum viable population (MVP) criteria. This bighorn habitat evaluation procedure combines (1) a quantitative assessment of bighorn range to determine if there are adequate quantities of resources to support an MVP of bighorn sheep, and (2) a qualitative assessment of a range to predict the probable density of bighorns the range can support. Extensive literature review, intensive bighorn research, and a modeling tool, pattern recognition …

Observations On The Developmental Biology Of Cicindela Arenicola Rumpp (Coleoptera: Cicindelidae), Karen Lyn Bauer

Great Basin Naturalist

Cicindela arenicola Rumpp is being considered for threatened and endangered status by the U.S. Fish and Wildlife Service. Little is known about the developmental biology of this species.

Adults of C. arenicola were active from April through late June and late August through early November, but generally they were not on the surface when temperatures were below 19 C or above 45 C, or when conditions were windy, cloudy, or rainy. Mating and egg-laying occurred only during the spring.

Five size classes (1-, 2-, 3-, 4-, and 5-mm diameters) of larval burrow openings were observed. Burrows of 5 mm had …

Physical Characteristics Of Blue Grouse Winter Use-Trees And Roost Sites, Peter J. Pekins, Frederick G. Lindzey, James A. Gessaman

Great Basin Naturalist

Physical characteristics of winter use-trees and roost sites of Blue Grouse (Dendragapus obscurus) were studied in northeastern Utah. Blue Grouse selectively roosted in the largest Douglas-fir (Pseudotsuga menziesii) trees during the day and subalpine fir (Abies lasiocarpa) trees at night. Diurnal and nocturnal roosts were typically adjacent to tree trunks in the lower two-thirds of trees. Nocturnal roosts provided greater canopy and denser shelter than diurnal roosts. Roost site selection was consistent with occupation of favorable microhabitat, particularly at night, and foraging strategy during the day. Timber management strategies should perpetuate large trees within …

Effects Of Convict Cichlids On Growth And Recruitment Of White River Springfish, Dallas Tippie, James E. Deacon, Chih-Hsiang Ho

Great Basin Naturalist

Observations of changes in population density of native White River springfish (Crenichthys baileyi) in Pahranagat Valley led to the following hypothesis: introduced convict cichlids (Cichlasoma nigrofasciatum) cause reduced growth and recruitment; cover reduces the magnitude of the effect. The hypothesis was tested by establishing sympatric and allopatric groups of the two species in experimental aquaria with and without cover. Change in volume (= mass) and length of the two species over a three-month period in spring 1986 and 1987 was measured and analyzed using 2 × 2 factorial analyses. Convict cichlids caused reduced growth and eliminated …
