Zoogeography Of Reptiles And Amphibians In The Intermountain Region, Wilmer W. Tanner Mar 1978

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.
Distribution maps of our modern species and …


The Theory Of Insular Biogeography And The Distribution Of Boreal Birds And Mammals, James H. Brown Mar 1978

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 …

Phytogeographical Variation Within Juniper-Pinyon Woodlands Of The Great Basin, Neil E. West, Robin J. Tausch, Kenneth H. Rea, Paul T. Tueller Mar 1978

Phytogeographical Variation Within Juniper-Pinyon Woodlands Of The Great Basin, Neil E. West, Robin J. Tausch, Kenneth H. Rea, Paul T. Tueller

Great Basin Naturalist Memoirs

About 22 percent of the pigmy conifer woodlands of the United States occur within the Great Basin. Only a very few reports of these woodlands exist in the literature. Available reports are either of general descriptive nature or specific analysis of vegetation-environmental relationships on one mountain range. In order to better understand basin-wide synecological patterns, a cooperative study was carried out by personnel at Utah State University and the University of Nevada-Reno between 1972 and 1975. Vegetation, landform, geology, and soils data obtained from 463 systematically placed stands on a randomly chosen set of 66 mountain ranges have been used …

Biogeography Of Intermountain Fishes, Gerald R. Smith Mar 1978

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 Mar 1978

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 Mar 1978

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 Mar 1978

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 Mar 1978

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 Mar 1978

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 …


Distribution And Phylogeny Of Eriogonoideae (Polygonaceae), James L. Reveal Mar 1978

Distribution And Phylogeny Of Eriogonoideae (Polygonaceae), James L. Reveal

Great Basin Naturalist Memoirs

Eriogonoideae is a subfamily of the knotweed family, Polygonaceae, endemic to the New World, and is composed of 14 genera and perhaps 320 species. It differs primarily from the other members of Polygonaceae in lacking well-defined sheathing stipules or ochrea. The species of Eriogonoideae vary from tiny, fragile annuals to herbaceous perennials, low subshrubs or shrubs to large and often arborescent shrubs. The seemingly most primitive extant genus of the subfamily is Eriogonum (247 species), which is widespread in central North America. A series of genera are closely related to Eriogonum, and probably have evolved directly from Eriogonum. These …


Problems In Plant Endemism On The Colorado Plateau, Stanley L. Welsh Mar 1978

Problems In Plant Endemism On The Colorado Plateau, Stanley L. Welsh

Great Basin Naturalist Memoirs

The problem of distribution of plant endemics is explored, especially as regards distribution of these plant species on elevational and substrate bases. Endemics per unit area are greater at elevations above 1980 m and on finely textured soils. A summary of data and a list of references is presented.


Some Factors Governing Plant Distributions In The Mojave–Intermountain Transition Zone, Susan E. Meyer Mar 1978

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 …


Alpine Phytogeography Across The Great Basin, W. D. Billings Mar 1978

Alpine Phytogeography Across The Great Basin, W. D. Billings

Great Basin Naturalist Memoirs

Alpine vegetations and floras are compared in two transects across the Intermountain Region. The first extends from the Beartooth Mountains in the central Rocky Mountains to the Sierra Nevada some 1200 Km to the southwest. It includes six mountain ranges. The second transect crosses the Mohave Desert from Olancha Peak in the southern Sierra Nevada to Charleston Peak and thence to San Francisco Peaks in northern Arizona. The largest numbers of arctic-alpine species are in the Beartooth and Ruby mountains, indicating migrations of these species along the Rocky Mountain cordillera. The lowest numbers of arctic-alpine species are in the central …


Patterns Of Avian Geography And Speciation In The Intermountain Region, Ned K. Johnson Mar 1978

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 …

Explosive Evolution Of Perennial Atriplex In Western America, Howard C. Stutz Mar 1978

Explosive Evolution Of Perennial Atriplex In Western America, Howard C. Stutz

Great Basin Naturalist Memoirs

New habitats opened up in western North America since the recession of Lake Bonneville and Lake Lahontan have admitted a host of new species of Atriplex. Every known evolutionary force is operating and at accelerated paces. Autoploidy appears to be more common than in any other reported group of plants. Natural hybridization between closely related species has provided a wealth of fertile segregants from which new adaptive types have been and are being selected. Hybrids between more distantly related species are sterile and some appear to have given rise to fertile alloploid derivatives.
All evidence points to a center of …
