An Addition To The Amphibian Fauna Of California, David A. Mullen, Robert C. Stebbins

Great Basin Naturalist

A population of salamanders of the genus Ambystoma has been found at Grass Lake, Siskiyou County, in Northern California. A five-year study has established that the salamanders are reproducing successfully and may represent a relictual population of native amphibians. The Grass Lake area has a sparse human population, which may help to explain how this secretive amphibian could have escaped notice. Attempts to determine the taxonomic position of the Grass Lake salamander, through comparisons of body measurements and coloration with those of other western ambystomatids, were inconclusive. These comparisons suggest, however, a close relationship with the geographically most proximate subspecies, …

Similarity Between Pronghorn And Mule Deer Fecal Pellets, Mark K. Johnson, James G. Maccracken

Great Basin Naturalist

Botanical compositions and pH values for pronghorn (Antelocapra americana) and mule deer (Odocoileus hemionus) fecal pellets from the Idaho National Engineering Laboratory Site were different. As there was no overlap between ranges of the herbivores fecal pH values, the fecal pH technique is a valuable tool for distinguishing between fecal pellets of pronghorn and mule deer on the study area.

Growth Of Dipodomys Ordii (Rodentia: Heteromyidae), H. Duane Smith, Gary H. Richins, Clive D. Jorgensen

Great Basin Naturalist

Growth rates were determined for laboratory-reared Dipodomys ordii pallidus Durrant & Setzer. Instantaneous growth rates were used to express increase of body weight, total length, tail length, ear length and hind foot length as rates between times of measurements and the instantaneous percentage of maximum size. Data were analyzed for growth periods of 1–3, 4–15, 16–29 and 30–70 days. All five parameters provided significant correlations of growth with age during all growth periods. Even though all of the growth parameters correlate with age, these parameters cannot be reliably used to predict age.

Leo Schelbert And Hedwig Rappolt, Eds,: Alles Ist Ganz Anders Hier, Bruno Gujer

Swiss American Historical Society Newsletter

To emigrate to the United States today does not seem to be the great adventure anymore that it once was. The material inconveniences of the move are negligible, the problems of psychological adjustment trivial compared to the physical hardships and culture shocks endured by the immigrants in the eighteenth and nineteenth century.

Endangered And Threatened Plants Of Utah: A Reevaluation, Stanley L. Welsh

Great Basin Naturalist

Endangered and threatened plants of Utah are reevaluated. The lists are brought up to date, and species now known to be common are recommended to be removed from the proposed lists. Additional species are proposed to be added, including the new species, Astragalus montii Welsh.

Vertebrate Fauna Of A Radioactive Leaching Pond Complex In Southeastem Idaho, Douglas K. Halford, Jere B. Millard

Great Basin Naturalist

An inventory of the terrestrial vertebrate fauna and the seasonal occurrence of each species was determined for a man-made radioactive leaching pond complex in southeastern Idaho. Three reptile, 11 mammal, and 94 bird species were identified from February 1974 through January 1978. Fewest species were observed during the winter and most during the summer. Eight bird species nested at the pond complex, while 19 species of birds were common or seasonally abundant. It appears that the Test Reactor Area radioactive leaching pond complex is an important water source and provides habitat for some species of wildlife.

Zoogeography Of Reptiles And Amphibians In The Intermountain Region, Wilmer W. Tanner

Great Basin Naturalist Memoirs

Few, if any, amphibians and reptiles are endemic to Utah. This is also true for much of the Great Basin, upper Colorado Plateau, southern Idaho, and Wyoming. Many species that would seemingly survive in this inland, mountainous area are not here. Only one widespread salamander and a few frogs and toads have occupied suitable habitats in the area. Lizards and snakes, like the amphibians, provide few distributions that extend throughout the area. A migration which presumably followed the Pleistocene Ice Age brought most of the species into the area as climatic conditions warmed.

The Theory Of Insular Biogeography And The Distribution Of Boreal Birds And Mammals, James H. Brown

Great Basin Naturalist Memoirs

The present paper compares the distribution of boreal birds and mammals among the isolated mountain ranges of the Great Basin and relates those patterns to the developing theory of insular biogeography. The results indicate that the distribution of permanent resident bird species represents an approximate equilibrium between contemporary rates of colonization and extinction. A shallow slope of the species-area curve (Z = 0.165), no significant reduction in numbers of species as a function of insular isolation (distance to nearest continent), and a strong dependence of species diversity on habitat diversity all suggest that immigration rates of boreal birds are sufficiently …

Biogeography Of Intermountain Fishes, Gerald R. Smith

Great Basin Naturalist Memoirs

Eighty-three species of fishes belonging to 26 genera live in the area bounded by the Sierra Nevada, Grand Canyon, Rocky Mountains, and Snake River Plain. The waters inhabited by these fishes are part of the Great Basin, Colorado River, Snake River, upper Pit River and upper Klamath River drainages. The adaptations and distribution patterns of these fishes have been shaped by extensional faulting and volcanic activity in the Great Basin, uplift of the surrounding ranges and plateaus, and cyclic fluctuations of the Pleistocene pluvials and interpluvials. Fossil evidence indicates that in the Pliocene many of the lineages had established distributions …

Avian Biogeography Of The Great Basin And Intermountain Region, William H. Behle

Great Basin Naturalist Memoirs

There are no endemic species of birds in the Great Basin. Nevertheless, a distinctive Great Basin avifauna exists which contains components of the Mojave Desert, Rocky Mountain, and Great Plains avifaunas as well as species obligate to sagebrush and the pinyon-juniper forest. Seemingly there has been little spread of California and Sierra Nevada species eastward, but a westward extension from the Rocky Mountains of several species is indicated. While several Rocky Mountain species reach their western limits on the eastern edge of the Great Basin, others have extended into the eastern portion. Two Great Plains representatives are late arrivals, namely …

The Flora Of Great Basin Mountain Ranges: Diversity, Sources, And Dispersal Ecology, K. T. Harper, D. Carl Freeman, W. Kent Ostler, Lionel G. Klikoff

Great Basin Naturalist Memoirs

The high elevation floras of 9 mountainous "mainlands" (3 in the Sierra-Cascade system and 6 in the High Plateau-Wasatch-Teton system) and 15 isolated mountain "islands" in the Intermountain Region have been analyzed. Mainland floras support more species per unit area and show a smaller increase in diversity as area is increased than islands (never exceeding 5 percent of any flora), however; and the island floras are overwhelmingly dominated by species with no apparent modifications for long-range dispersal. Furthermore, the eastern mainland has exerted a far greater influence on the flora and the vegetation of the islands than has the western …

Applying Biogeographic Principles To Resource Management: A Case Study Evaluating Holdridge's Life Zone Model, James A. Macmahon, Thomas F. Wieboldt

Great Basin Naturalist Memoirs

Conservation schemes require some portioning of the world into a discrete number of subunits which might benefit from similar management practices. The Holdridge Life Zone scheme, proposed for such purposes previously, is applied to Utah as an initial test of its usefulness. A hypothetical life zone map was developed entirely on the basis of weather station data and data derived from these values. This predictive map compared favorably to data on patterns of vegetation, mammal, reptile, and amphibian distribution in Utah.

Biogeography And Management Of Native Western Shrubs: A Case Study, Section Tridentatae Of Artemisia, E. Durant Mcarthur, A. Perry Plummer

Great Basin Naturalist Memoirs

Biogeographical considerations are important in the management of western shrublands. Seedings on rangelands have a higher probability of success when tried and tested principles are followed. It is usually best to seed mixtures that include adapted shrubs and herbs. Shrubs generally are well adapted to the environmental extremes of western ranges. Throughout the year, they provide nutrients for herbivores that are only seasonably available in herbs.

Section Tridentatae of Artemisia is endemic to western North America and distinct from the analogous Eurasian section (or subgenus) Seriphidium. The groups have separate, distinguishable centers of diversity; the two groups seem to be …

The Biota Of The Intermountain Region In Geohistorical Context, Arthur Cronquist

Great Basin Naturalist Memoirs

The present Great Basin Floristic Province had achieved roughly its present topographic conformation by some time in the Miocene epoch and had a climate not too different from the present one, though probably a little warmer, moister, and less continental. Both the flora and the fauna took on a fairly modern aspect during the Miocene, as a result of worldwide evolutionary changes and more specific adaptation to the conditions of the region. Changes in the biota since that time mainly reflect evolution and migration at the level of species and, to a lesser extent, genera, in response to regional conditions …

Some Factors Governing Plant Distributions In The Mojave–Intermountain Transition Zone, Susan E. Meyer

Great Basin Naturalist Memoirs

The existence of a floristic transition zone can be inferred by the fact that a high proportion of indigenous plant species reach a distributional limit within the area. The vascular flora of Washington County, Utah, exhibits this character to a marked degree with 53.6 percent of the native flora reaching a distributional limit within the county. By looking at geographic distributions, ecological preferences, and range termination information for the component species, first approximations are made as to the probable factors mediating plant distributions within the county, particularly of the range-terminating species. The high proportion of range-terminating species in the flora …

Patterns Of Avian Geography And Speciation In The Intermountain Region, Ned K. Johnson

Great Basin Naturalist Memoirs

The Intermountain Region comprises a huge arena where major avifaunas more highly developed beyond the Great Basin come into contact. For this reason the distribution and composition of avifaunas in riparian and pinyon-juniper woodlands and in coniferous forests in this region are understood most clearly if considered as part of a broader system of patterns evident in western North America. Riparian woodland samples point to a complex meeting ground in the Intermountain Region of two major avifaunas of equivalent size, but from opposite distributional backgrounds. These northern and southern avifaunas do not mix among the samples represented except in western …
