A New Sciurid Of Blancan Age From Kansas And Nebraska, Claude W. Hibbard

Bulletin of the University of Nebraska State Museum (1924–2023)

The collecting of vetebrate fossils from deposits of Blancan age in Kansas, Nebraska, and Texas during the past twelve years has revealed many interesting forms. Some species have been found to have wide geographic distribution. A large sciurid related to the woodchucks has been recognized from both Kansas and Nebraska and is here described as a new genus and species.

Life Histories Of North American Nuthatches, Wrens, Thrashers And Their Allies: Order Passeriformes, Arthur Cleveland Bent

Papers in Ornithology

An attempt has been made to give as full a life history as possible of the best-known subspecies of each species and to avoid duplication by writing briefly of the others and giving only the characters of the subspecies, its range, and any -habits peculiar to it. In many cases certain habits, probably common to the species as a whole, have been recorded for only one subspecies. Such habits are mentioned under the subspecies on which the observations were made. The distribution gives the range of the species as a whole, with only rough outlines of the ranges of the …

Comparison Of Biotic Communities Of The Cedar-Hemlock And Oak-Hickory Associations, Final Version, Jane Claire Dirks-Edmunds

Jane Claire Dirks-Edmunds Documents

A revised version of the final draft of Dr. Jane Claire Dirks-Edmunds's doctoral dissertation was published in Ecological Monographs in 1947. In her dissertation, Dirks-Edmunds compared the Douglas fir forest community on Saddleback Mountain in Oregon to an oak-hickory community in Illinois. Dirks-Edmunds, a 1937 graduate of Linfield College, graduated from the University of Illinois in 1941; she returned to teach in the Biology department at Linfield from 1941-1974.

Aspen Properties And Uses, Zigmond A. Zasada

Aspen Bibliography

Because of the large demand for lumber during the last 10 years, and particularly during the war period, aspen has entered many new fields of use. At present there is widespread interest in the possibilities of building new industries and extending the life of old ones by increased use of aspen. Many people are interested in becoming familiar with this wood. This report has been prepared to give general information on the properties and present uses of aspen and also to help in correcting some of the existing erroneous ideas about this wood.

The Goss Lemming Mouse, Synaptomys Cooperi Gossii (Goues), In Nebraska, Edson Fichter, Merle F. Hansen

Bulletin of the University of Nebraska State Museum (1924–2023)

In the course of studies on the cestode parasites of microtine rodents by one of the authors (Hansen), specimens of mice were sent to the United State National Museum where they were identified by Dr. David H. Johnson. Two of these microtines proved to be Synaptomys cooperi gossii (Coues). These specimens of Synaptomys (U.S.N.M. Nos. 282343 and 282344), collected at Lincoln, Lancaster County, Nebraska, on September 16, 1946 (male) and November 20, 1946 (female), respectively, are the first ones to be identified from Nebraska.

The Geologic History Of The Bison In The Great Plains (A Preliminary Report), C. Bertrand Schultz, W. D. Frankforter

Bulletin of the University of Nebraska State Museum (1924–2023)

THE GEOLOGIC history of the bison in North America is a subject which has received little attention to date. Osteological rather than geological problems have been the main concern of most writers who have so far published. If the geologic history of the bison is to be learned, it will be necessary to devote more time and effort in the field in determining the age of the deposits in which various specimens have been discovered and in making more extensive collections from deposits of known age. Unfortunately the majority of the type specimens have been surface finds and little attempt …

Thrips Species Infesting Tomatoes And Other Host Plants Of These Insects In Northern Utah, Darrell R. Maddock

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The purpose of this study has been to determine which species of thrips infest tomato plants and fruits in northern Utah, and to find out which other plants occurring in this area also serve as hosts for tomato-infesting thrips.

Because of the importance of tomato-infesting thrips to the canning industry, it was decided that more complete knowledge of the species of thrips which are found on tomatoes should be obtained. Because most thrips generally have been difficult to control, it was believed that a general knowledge of the plants on which these thrips occur would enable tomato growers to eliminate …

Mirid-Bug Injury As A Factor In Declining Alfalfa-Seed Yields, Charles J. Sorenson

Faculty Honor Lectures

During the forty or more millions of years that insects have inhabited the earth they have developed remarkable adaptations and great powers of reproduction that have enabled them to spread over most of the world and occupy all of its habitable environments. In cultivating the land and in growing crops, man has disturbed the balance in nature which formerly prevailed. By doing this he has unwittingly assisted many insect species to multiply in unprecedented numbers by providing them with more delectable food in abundance and by transporting them from place to place and from continent to continent in his migrations …

Range Land Of America And Some Research On Its Management, Laurence A. Stoddart

Faculty Honor Lectures

Although grazing of livestock has been a practice and a profession of man almost from his beginning only recently has range management reached anything approaching a pre~ cise science. Although ' trials and errors over the years brought to light much practical methodology for assuring high production from grazing land, still it remained for the plant physiologist and ecologist to find the whys and wherefores, and to advance new methods and new thoughts which promise to increase productivity still further and at the same time maintain the great range resource.

The peculiar land situation that marked America in her forma~ …

Progress Report On The Ground-Water Resources Of The Las Vegas Artesian Basin, Nevada, George B. Maxey, C. Harry Jameson

Publications (WR)

Whether the tremendously increased population acquired by Las Vegas in the years 1940 to 1942 will be retained cannot at present be foretold. However, the valley will undoubtedly be expected to support a considerably larger population than it did at any time prior to 1940, and continually increasing demands on the water supply for innumerable pcacetimc activities must be anticipated. Therefore, a sound evaluation of tho ground water resources of Las Vegas Valley is directly in line with the other wisely progressive planning programs which are now operating or are taking shape in the valley as well as in the …

Seeding Grass On Deteriorated Aspen Range, A. Perry Plummer, George Stewart

Aspen Bibliography

The herbaceous undercover on much of the aspen range in the Intermountain region is badly deteriorated. These areas, naturally highly productive, when revegetated can contribute greatly towards a much needed supply of range forage. One of the major obstacles to successful seeding has been the difficulty of getting the seeds covered with soil since both standing and fallen trees interfere with the use of drills, harrows, or other machinery. In the search for methods to overcome this difficulty, it was found that for open aspen stands the covering of seeds is unnecessary when the right precautions are taken in other …

North American Prairie, J. E. Weaver

Papers of John E. Weaver (1884–1956)

From the highlands of central Mexico across the entire United States and northward into Canada extends the great mid-continental prairie. On the east it is in contact with the deciduous forest. From this central mass the prairie extends westward beyond the Rocky Mountains across Wyoming into eastern Utah, and southwestward through northern New Mexico in to northern Arizona. The Palouse Grasslands occurred in eastern Oregon and Washington, and other parts of the far Northwest. The Pacific Prairie was found in the Great Valley of California, and the-Desert Plains Grassland still occupies much of southern Arizona and New Mexico and southwestern …

Recovery Of Midwestern Prairies From Drought, John E. Weaver

Papers of John E. Weaver (1884–1956)

The long period of desiccation, which began in 1934, finally terminated in 1940. The western portion of True Prairie was greatly decimated and a veritable mosaic of types of vegetation resulted. These ranged from well-preserved relict communities of bluestems (Andropogon) to mixed stands of grasses on nearly bared soil, but included communities of western wheat grass (Agropyron smithii) , short grasses (Bouteloua gracilis and Buchloe dactyloides) , needle grass (Stipa spartea), and prairie drop seed (Sporobolus heterolepis) . These types varied in size from a few square rods to many …

How To Reseed Utah Range Lands, A. Perry Plummer, Richard M. Hurd, C. Kenneth Pearse

Aspen Bibliography

Additional low cost forage is urgently needed by Utah's range livestock industry. Seeding of depleted tracts in accordance with recently developed methods and principles will help supply this forage and is entirely feasible. Where the value of the increased forage will repay the cost of planting, careful reseeding of selected sites is fully justified.

The important part that reseeding can play in restoring ranges to their former capacity has been demonstrated. Although satisfactory results can be obtained on many sites during average or better years, much more study is needed to insure consistent success in abnormal years and to extend …
