The Role Of Pioneer Species In Revegation Of Disturbed Desert Areas, A. Wallace, E. M. Romney

Great Basin Naturalist Memoirs

The northern Mojave Desert, as are many deserts, is characterized in part by small "fertile islands" in which exist individual shrub clumps each containing two or more plants. These fertile sites promote characteristic organization of both plant and animal activity in the desert. Destruction of these fertile sites makes revegetation extremely difficult because most seedlings germinate in these sites. Some pioneer species do, however, germinate and survive in the bare areas between the fertile sites. Four such species in the northern Mojave Desert are Acamptopappus shockleyi Gray, Lepidium fremontii Wats., Sphaeralcea ambigua Gray, and Atriplex confertifolia (Torr. & Frem.) Wats. …

Distribution Of Photosynthetically Fixed 14C In Perennnial Plant Species Of The Northern Mojave Desert, A. Wallace, J. W. Cha, E. M. Romney

Great Basin Naturalist Memoirs

The distribution of photosynthate among plant parts subsequent to its production is needed to fully understand behavior of vegetation in any ecosystem. The present study, undertaken primarily to obtain information on transport of assimilates into roots of desert vegetation, was conducted in the northern Mojave Desert, where the mean annual rainfall is about 10 cm. Shoots of Ambrosia dumosa (A. Gray) Payne plants were exposed to ¹⁴CO₂ in1971, and the distribution of ¹⁴C in roots, stems, and leaves was subsequently measured at 1 week, 2 months, and 5months. Only about 12 percent of the ¹⁴C photosynthate …

The Pulse Hypothesis In The Establishment Of Artemisia Seedlings At Pahute Mesa, Nevada, E. M. Romney, A. Wallace, R. B. Hunter

Great Basin Naturalist Memoirs

New Artemisia seedlings are not established each year. Many that are established fail to survive because of unfavorable rainfall in succeeding years. A total of 184 young plants was examined for the number of annual growth rings to ascertain the year of establishment after all vegetation had been killed near the time of a nuclear test event in 1965. The three most important recent years for establishment and survival of new seedlings (as of 1976 and based on a sample of 184 plants) were 1966 (9 percent), 1969 (29 percent), and 1973 (36 percent). A total of 2 percent was …

Frequency Distribution And Correlation Among Mineral Elements In Lycium Andersonii From The Northern Mojave Desert, A. Wallace, E. M. Romney, G. V. Alexander, J. E. Kinnear

Great Basin Naturalist Memoirs

Two hundred samples of leaves of Lycium andersonii A. Gray, each representing one plant and divided among six different locations, were assayed by emission spectrography. Information for 12 different elements is reported in terms of concentrations, frequency distribution, correlations, and some soil characteristics. The objective was to ascertain the nature of variability for mineral elements within a species. Composition varied significantly for all 12 elements among locations, all within about 20 km. At least part of the variation was due to soil characteristics. Samples from Rock Valley were highest in K, Na, and Li, which effect is associated with volcanic …

Spatiotemporal Variation In Phenology And Abundance Of Floral Resources On Shortgrass Prairie, V. J. Tepedino, N. L. Stanton

Great Basin Naturalist

Phenology and abundance of the floral resources used by bees and other flower-visiting insects were recorded weekly from permanent quadrats for two years on two shortgrass prairie sites in the Laramie Basin, Wyoming. Each site was composed of three distinct plant communities. Results suggest considerable spatiotemporal variability in floral resources. Specifically, most species at both sites showed the following temporal variation: (1) bloom times between one and two weeks earlier in the second year; (2) differences of approximately 1–2 weeks in bloom span between years; (3) substantial differences in abundance of flowers between years. Species blooming during the last half …

Poisonous Plants Of Utah, Jack D. Brotherson, Lee A. Szyska, William E. Evenson

Great Basin Naturalist

A list of the major livestock-poisoning plants has been compiled for the state of Utah. Two hundred fifteen taxa representing 36 families, 119 genera, and 209 species occur within the state. Forty-one percent are from two families, the Asteraceae and the Fabaceae. The remaining families of major importance are: Poaceae, Ranunculaceae, Solanaceae, Chenopodiaceae, Brassicaceae, Ascelpiadaceae, Liliaceae, and Euphorbiaceae. Sixty-nine percent of the genera occur with a single species. Thirty-three percent of the taxa are introduced to the state. Most of the plants are insect pollinated; 57 percent are herbaceous perennials.

Most livestock poisoning occurs during the spring. This is due …

Observations On Seasonal Variation In Desert Arthropods In Central Nevada, Robert D. Pietruszka

Great Basin Naturalist

Pitfall and Malaise trap collections from terrestrial arthropod populations in central Nevada were analyzed for four trapping periods during the 1978 growing season. Mites (Acarina) and ants (Formicidae) were the taxa represented by the largest numbers of individuals in pitfall trap collections throughout the season; Malaise collections were composed mainly of aerial taxa (largely Diptera and Hymenoptera). Peak arthropod abundance was recorded during mid-June. Collection diversities for both trapping methods were generally low due to the abundance of a few taxa. Evidence for spatial heterogeneity in arthropod populations was meager; temporal heterogeneity in these populations, however, was more apparent.

Comparative Floral Biology Of Penstemon Eatonii And Penstemon Cyananthus In Central Utah: A Preliminary Study, Lucinda Bateman

Great Basin Naturalist

A comparison of the floral visitors of two closely related plant species, Penstemon cyananthus and P. eatonii suggests that flower shape and color may affect the number and type of pollinators, and the ability of the plant to set fruit. Penstemon cyananthus, which is most attractive to hymenopteran visitors, has a blue flower, large in diameter, that is positioned as a convenient "landing pad." Although many types of insects visit the flower, the transport of pollen directly to flowers of another individual of the same species is somewhat inefficient, since fruiting success is low (66.7 percent). The tubular red flowers …

Relationships Among Total Dissolved Solids, Conductivity, And Osmosity For Five Artemia Habitats (Anostraca: Artemiidae), Nicholas C. Collins, Gray Stirling

Great Basin Naturalist

Graphs allowing interconversion between various physical chemical parameters are presented for five Artemia habitats in the western USA. Both the mean osmosity and its typical yearly range differ greatly among habitats. Consequently, Artemia populations provide an interesting opportunity to study physiological and life history adaptations to differing degrees of habitat stability.

Identity Of Narrow-Leaved Chysothamnus Viscidiflorus (Asteraceae), Loran C. Anderson

Great Basin Naturalist

Two groups of glabrous, narrow-leaved Chrysothamnus viscidiflorus (Asteraceae) are perceived, and appropriate taxonomic combinations are made, i.e., C. v. ssp. viscidiflorus var. stenophyllus and C. v. ssp. axillaris. The two are fairly distinct geographically, and they can be separated by floral morphology. A key to all species of section Chrysothamnus (to which C. viscidiflorus belongs) is given.

Feeding Ecology Of Gila Boraxobius (Osteichthyes: Cyprinidae) Endemic To A Thermal Lake In Southeastern Oregon, Jack E. Williams, Cynthia D. Williams

Great Basin Naturalist

Gila boraxobius is a dwarf species of cyprinid endemic to a thermal lake in southeastern Oregon. Despite a relatively depauperate fauna and flora in the lake, 24 food items were found in intestines of G. boraxobius. Ten of the 24 foods, including six insects, were of terrestrial origin. The relative importance of food items fluctuated seasonally. Diatoms, chironomid larvae, microcrustaceans, and dipteran adults were the primary foods during spring. In summer, diatoms decreased and terrestrial insects increased in importance. During autumn important foods were terrestrial insects, chironomid larvae, and diatoms. Diatoms and microcrustaceans increased in importance during winter. Chironomid larvae …

Parasites From Two Species Of Suckers (Catostomidae) From Southern Utah, J. Craig Brienholt, Richard A. Heckmann

Great Basin Naturalist

Twenty Catostomus latipinnis and 50 Catostomus discobolis from La Verkin Creek and the Fremont River in southern Utah were collected and surveyed for parasites. Data from the survey indicated that 83 percent of the fish were infected with at least one parasite, with the fish from La Verkin Creek harboring more parasites. Twelve genera and 12 species of parasites were identified from these fish. A monogenetic trematode, Gyrodactylus elegans, which was found in 90 percent of the fish, was the most common parasite. Comments are included on habitat and host variations for the parasitofauna from suckers taken from the two …

Stinger Utilization And Predation In The Scorpion Paruroctonus Boreus, Bruce S. Cushing, Anne Matherne

Great Basin Naturalist

The utilization of the stinger and the predatory technique of the scorpion, Paruroctonus boreus, was studied under laboratory conditions. During the study, 83 feedings were observed. Age of the scorpions and the percentage of prey stung by them were used to classify the scorpions into groups. The scorpions aged 13–61 days always stung prey. After 62 days the scorpions began to selectively utilize the stinger. Utilization declined until it reached 30 percent in the adult stage. The stinger is apparently necessary for prey capture only in the early life stages.

Short-Term Effects Of Logging On Red-Backed Voles And Deer Mice, Thomas M. Campbell Iii, Tim W. Clark

Great Basin Naturalist

Clearcutting and selective logging effects on red-backed voles (Clethrionomys gapperi) and deer mice (Peromyscus maniculatus) were studied (September–November, 1975; June–October, 1976) in Bridger–Teton National Forest, Wyoming. Five selective cuts (total 137 ha) removed 57 percent (range 34–74 percent) of the trees. One clearcut (9.6 ha) eliminate 84 percent of the trees. Soils remained mesic in selective cuts, but became xeric in the clearcut. Snap-trapping indicated that voles were most abundant on the unlogged and selectively cut mesic sites (76 percent of 408 captures), whereas deer mice were more common on the xeric clearcut (80 percent of …

Some Aspects Of Succession In The Spruce-Fir Forest Zone Of Northern Utah, David J. Schimpf, Jan A. Henderson, James A. Macmahon

Great Basin Naturalist

A site in the Rocky Mountain subalpine forest zone with which a series of hypotheses concerning ecosystem succession was tested is characterized. Succession from herb-dominated meadows to climax forests of Engelmann spruce and subalpine fir can follow at least four identified pathways. After fire, spruce and fir may reinvade a site directly, follow invasion by aspen, or follow invasion by lodgepole pine, the pathway depending on a combination of physical and biotic factors. In other cases, succession begins with long-established meadows which do not owe their existence to fire. In this latter pathway, aspen invades meadows by suckering and changes …
