Perennial Atriplex Of Utah And The Northern Deserts, Craig A. Hanson
Perennial Atriplex Of Utah And The Northern Deserts, Craig A. Hanson
Theses and Dissertations
Atriplex is a genus in the Chenopodiaceae, the perennial members of which are ecologically important in western North America. Seventeen species and one subspecies of perennial Atriplex occur in Utah and the northern deserts. Three of these species and the subspecies were described by the writer in a recent publication as a result of extensive field work leading to this study. These are A. welshii, A. navajoensis, A. bonnevillensis, and A. cuneata ssp. introgressa. This study is an investigation of the systematics and phytogeography of the perennial Atriplex in Utah and the northern deserts, with emphasis on the A. gardneri …

An Ecological Study Of An Exclosure In The Mountain Brush Vegetation Of The Wasatch Mountains, Utah, Elray S. Nixon
An Ecological Study Of An Exclosure In The Mountain Brush Vegetation Of The Wasatch Mountains, Utah, Elray S. Nixon
Theses and Dissertations
This is a comparative study of the vegetation and soils of an exclosure in the mountain brush vegetation of the Wasatch Mountains, Utah. The exclosure was fenced and initially analyzed during the summers of 1949-1950. The study area is located in Pole Canyon in the Uinta National Forest, a few miles northeast of Provo, Utah. The dominant woody species of the vegetation in the exclosure are big toothed maple (Acer grandidentatum) and Gambel oak (Quercus gambelii). After settlement of the area in and around Provo, Pole Canyon became overgrazed by livestock. Since 1949 the area has been protected from grazing. …

The Natural History Of Necturus, Iv. Reproduction, Joseph P. Harris Jr.
The Natural History Of Necturus, Iv. Reproduction, Joseph P. Harris Jr.
Journal of the Graduate Research Center
Information on the life cycle of Necturus has accumulated slowly. Naturalists long were uncertain as to whether they had adult animals, since Mitchill's (1822) mistaken idea that they get to be two feet long was widely current. Lacepede (1807) believed that mudpuppies might be larval, and their adults unknown; Say (1818) that the mud puppy was the larva of the hellbender. Barton (1807) confused the mudpuppy and the hellbender. Gray (1857) was "... inclined for the present to consider the Proteus of the Lakes as a distinct kind of Batrachian, which is arrested in its development, and never reaches the …
Types Of Farming In Poland, Jerzy Kostrowicki
Types Of Farming In Poland, Jerzy Kostrowicki
Journal of the Minnesota Academy of Science
Thus the Polish study presented here is but one more attempt to solve some methodological problems and to arrive at a typology of agriculture for a single country. In the Polish study, a type of farming is understood as being shaped under given natural conditions by particular social and economic processes: an ensemble of ways, orientations, and results of farming.
Relationship Of Certain Environmental Factors To Benthic Fish Densities In Bear Lake, Idaho-Utah, Thomas J. Hassler
Relationship Of Certain Environmental Factors To Benthic Fish Densities In Bear Lake, Idaho-Utah, Thomas J. Hassler
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
The project was initiated in June of 1958 and financed by the National Science Foundation and the Wildlife Management Department of Utah State University.
The broad aspects of the study were to determine if a relationship exists between certain physical and biological factors and benthic fish densities. The project vas divided into two parts: (l) to determine the time and extent of thermal stratification, zooplankton densities, conductivity changes within the lake and conductivity differences between the lake and its tributaries; (2) to determine it a relationship exist between benthic fish densities, temperatures, depths, conductivities and benthic zooplankton densities. The data …
East Texas: A Timbered Empire, Edwin J. Foscue
East Texas: A Timbered Empire, Edwin J. Foscue
Journal of the Graduate Research Center
The forest-covered portion of East Texas, with an area of approximately 28,000 square miles, is larger than Vermont, New Hampshire, and Massachusetts combined (Fig. 1). The timbered region, which represents about one-eighth of the total area of the state, has contributed so much to the history and economic development of Texas that it deserves to be better known.

In the last issue of Field & Laboratory (26, 86-139) appeared the first 331 sketches (Abadie to Gilbert) of collectors, explorers, and observers, in a series that will extend through several issues. My fears of omissions were justified: I find that a sketch of Samuel Botsford Buckley (1809-84), a graduate of Wesleyan University in Connecticut, and twice State Geologist of Texas (1866-7 and 1874-5) was unaccountably omitted. This omission is the more notable since for twenty years I have been holding in abeyance the publication of a sketch of Buckley (on whom I have very extensive materials) waiting for a …

Recently there came back into my hands a lent-and forgotten-dossier of 1929 correspondence with Swiss and German universities and libraries-a correspondence dealing with the Swiss naturalist, Jacob Boll, who spent the last years of his life in Texas. His life, with that of other naturalists, is sketched in my Naturalists of the Frontier (1937, 1948). Such a recovery reminds one of the passing of time, and a long-made promise to put into print an account of the men of science (sit venia verbo) of Early Texas. Most of them were men of other trades, professions, what-you-will, of good amateur standing; …
Climatic Variations In South Dakota 1900 - 1950, Robert M. Basile
Climatic Variations In South Dakota 1900 - 1950, Robert M. Basile
Agricultural Experiment Station Agricultural Economics Pamphlets (1941-1991)
Most of South Dakota lies within the Great Plains of the United States. Thus, the climate of South Dakota, like that of the Great Plains, has been one of relatively little precipitation and frequent droughts. However, periods of rather high rainfall have led to considerable optimism. Likewise droughts like those of the 1930's may have led to too much pessimism. What is the real picture of the variability of South Dakota climate? The purpose of this pamphlet is to help answer this question. No one knows with certainty what will happen in the future. The best indication of what can …
The Occurrence And Distribution Of Birds On Middleton Island, Alaska, Robert L. Rausch
The Occurrence And Distribution Of Birds On Middleton Island, Alaska, Robert L. Rausch
Harold W. Manter Laboratory of Parasitology: Faculty Publications
A survey of the birds of Middleton Island was made in June 1956. Forty-five species of birds were recorded. Of these, at least 16 species were breeding, four other species were possibly breeding, and 2.5 species were regarded as transients. The distribution of the breeding birds was correlated with six major ecological formations. Five of the latter were based on vegetational characteristics, while the rocky cliffs comprised the sixth.
The avian fauna of Middleton Island consists mainly of species found in the Prince William Sound region, to the north. An important exception was the Lapland Longspur, which previously has not …
The Cattle Industry Of San Juan County, Utah, 1875-1900, Franklin D. Day
The Cattle Industry Of San Juan County, Utah, 1875-1900, Franklin D. Day
Theses and Dissertations
The purpose of this study was to learn the reasons for the movement of cattle Into San Juan County, Utah, the development of the Industry, and its contribution to the growth of the county.
The few written accounts in existence of the cattle industry in San Juan are brief and found in widely separate areas. The whole and complete account will likely never be written, but there is need for gathering as much of the scattered information as possible.
A study of the early history of the inhabitants of San Juan was made, along with an examination of the geography …
Geology Of The Ferris Quadrangle, Dallas And Ellis Counties, Texas, Donald F. Reaser
Geology Of The Ferris Quadrangle, Dallas And Ellis Counties, Texas, Donald F. Reaser
Field and Laboratory
The Ferris Quadrangle in southern Dallas and northern Ellis counties, Texas, is underlain by the Austin Chalk and Taylor Marl, both of Upper Cretaceous age. Two members of the Austin, the middle marl and the upper chalk, along with the lower blue-gray unit of the Taylor Marl, crop out within the area. The Austin-Taylor contact, within the area in Dallas County, is transitional and consists of chalk and marl sequences intermediate in lithology between the two formations. The contact in Ellis County is marked by a reddish-brown clay zone containing phosphate nodules, indicating an unconformity. Approximately one-half of the area …
Gustavus Wilhelm Wuerdemann (1817-59), Early Naturalist Of The U.S. Coast Survey, S. W. Geiser
Gustavus Wilhelm Wuerdemann (1817-59), Early Naturalist Of The U.S. Coast Survey, S. W. Geiser
Field and Laboratory
The recent appearance of Wraight & Roberts' sequicentennial historical account of the U.S. Coast & Geodetic Survey calls to mind the splendid natural-history collections that G. W. Wurdemann, tidal-observer and meteorologist, made during the years 1844 to 1859, especially in Texas, Louisiana, and Florida. As no extended biographical notice of this naturalist has appeared in the nearly one-hundred years that have passed since his death, the present note may be of interest to students of the history of scientific exploration in the early South and Southwest.

Francois Crepin On Botanizing, Lloyd H. Shinners
Francois Crepin On Botanizing, Lloyd H. Shinners
Field and Laboratory
Late in the 19th Century the younger Hooker was led to exclaim to some of the botanical students of the day, "You young men do not know your plants!" What would he think of the modern graduate in botany? Now one gets a Ph.D. in the science without knowing most of the plants he encounters every day. Chromosomes, statistics, fancied phylogenies, current fads in morphology and physiology--about such things, like the modern major general, he is "teeming with a lot of news," at least until oral exams are over. If he goes on to teach, it will be to relay …

Nebraska Deer, William Bailey Jr., George Schildman, Phillip Agee, C. G. Pritchard
Nebraska Game and Parks Commission: Publications
IN COMMON with the experience of most states, Nebraska's deer herds were reduced to a very low level by excessive harvests in our early history. Most American big-game animals were overharvested in the early history of this nation because of commercialization. Buffalo were killed for their hides, deer for their meat. This slaughter continued as long as the hunter (or poacher) could sell his take at a profit. Modem game management and public opinion reversed this trend. Deer are on the way back all over America, and in some states the protection-complex was so strong that deer were restored to …

Studies On The Helminth Fauna Of Alaska. Xxv. The Ecology And Public Health Significance Of Echinococcus Sibiricensis Rausch & Schiller, 1954, On St. Lawrence Island, Robert L. Rausch, Everett L. Schiller
Harold W. Manter Laboratory of Parasitology: Faculty Publications
The occurrence of a species of Echinococcus (Rudolphi, 1801) on St Lawrence Island was noted by the writers in early 1950. Recognition of its unusual host relationships led to an investigation of the ecology of this cestode, E. sibiricensis Rausch & Schiller, 1954. It is the purpose of this paper to report the results of this work, with emphasis on alveolar hydatid disease in man, of which this cestode is the etiologic agent.
