The Early Basis Of Subsistence Of Indians In The Plains Area, Joe D. Reed
Biology ETDs
The fundamental purpose of this paper is to present the picture of early food economy among the Indians of the Plains. In order to accomplish this task the procedure has been to present: (1) a brief study of the tribal groups with special emphasis upon their early history and movements, followed by (2) a general picture of Plains food economy with regard to the sequence and tribal units. The important subjects within this second category have to do with buffalo utilization, agriculture and the gathering to wild plant food; (3) a listing of the various wild plant and animal foods …

A New Fossil Bovid From Nebraska With Notice Of A New Bison Quarry In Texas, C. Bertrand Schultz
A New Fossil Bovid From Nebraska With Notice Of A New Bison Quarry In Texas, C. Bertrand Schultz
Bulletin of the University of Nebraska State Museum (1924–2023)
An interesting and unique bovid skull was reported to the staff of the University of Nebraska State Museum in 1938 by Mr. Alvin McReynolds of Nehawka, Nebraska. The specimen was found in 1933 in a ravine north of Nehawka by Messrs. Merritt and Harold Dodson, brothers. Although the skull was not in place, it appears to have been washed out of a nearby Pleistocene clay deposit by floodwaters. The specimen is well preserved and is of a dark brown, almost black color. In 1938 it was loaned to the Museum for study and photographing but was not obtained as a …

The Ancestral Ursid, Hemicyon, In Nebraska, Edwin H. Colbert
Bulletin of the University of Nebraska State Museum (1924–2023)
During the summer of 1928, a University of Nebraska State Museum field party, composed of Dr. A. L. Lugn and the writer, made a collection of upper Miocene and lower Pliocene mammals in Brown and Cherry counties, Nebraska. This collection was sponsored and made possible by the generosity of the late Hon. Charles H. Morrill.
A Shovel-Tusked Mastodon, Arnebelodon Fricki, From Kansas, Erwin Hinckley Barbour, Claude W. Hibbard
A Shovel-Tusked Mastodon, Arnebelodon Fricki, From Kansas, Erwin Hinckley Barbour, Claude W. Hibbard
Bulletin of the University of Nebraska State Museum (1924–2023)
Since the Amebelodontinae were first announced (Barbour 1927), a number of examples of the genus Amebelodon have presented themselves in various parts of Nebraska, Colorado, and in several places in Kansas. Thus its range has already been materially extended, many skeletal parts added, and the hope kindled that knowledge of this remarkable group of proboscideans is destined to be greatly enriched within the next few years. As may be seen in the accompanying lists of the known parts of Amebelodon preserved in various museums, there are already at hand the bones necessary for the assemblage of a nearly complete composite …
A New Species Of Sphenophalos From The Upper Ogallala Of Nebraska, Erwin Hinckley Barbour, C. Bertrand Schultz
A New Species Of Sphenophalos From The Upper Ogallala Of Nebraska, Erwin Hinckley Barbour, C. Bertrand Schultz
Bulletin of the University of Nebraska State Museum (1924–2023)
The genus Sphenophalos was described by John C. Merriam (1909, p. 319-30), who based his description on a fragmentary horn-core (Uni. of Calif. No. 11887) from the late Tertiary deposits near Thousand Creek in northern Humbolt county, Nevada. Knowledge of Sphenophalos, however, is still confined to this single, fragmented type horn-core (Frick 1937, p. 472) and other fragmental specimens (Furlong 1932, p. 27-36).
The Pipy Concretions Of The Arikaree, C. Bertrand Schultz
The Pipy Concretions Of The Arikaree, C. Bertrand Schultz
Bulletin of the University of Nebraska State Museum (1924–2023)
The pipy concretions of the Arikaree (lower Miocene) of Nebraska and adjacent states were first described by Nelson Horatio Darton (1899, p. 743) as "characteristic layers of hard, fine-grained, dark-gray concretions, often consisting of aggregations of long, irregular, cylindrical masses" (see Figures 30, 32, 34, and 35). The individual pipes vary in diameter from a few inches to several feet, and in length from a few inches to a hundred yards or more. Tests demonstrate that pipy concretions are composed of sand cemented by calcium carbonate. When dipped in acid the cement is dissolved and the concretion is reduced to …

A Study Of The Geographical And Ecological Distribution Of The Buffy Plains Pocket Mouse (Perognathus Flavescens Flavescens), With Description Of A New Subspecies From Nebraska, Myron H. Swenk
University of Nebraska State Museum: Mammalogy Papers
The Buffy Plains Pocket-mouse (Perognathus flavescens flavescens) is a typical mammal of the Sandhill Region of Nebraska. Its home, like that of other species of pocket-mice, is a series of burrows in the ground, consisting of several entrance holes leading to the main 'burrow, in which is located the nest and the food storage chambers. In the Nebraska sandhills its burrows and nests are commonly placed beneath clumps of Spanish Bayonet or Prickly Pear Cactus, and the entrance holes usually are so distributed as to open from under the plant in all directions.
The writer had hoped to …
A Survey Of Human Intestinal Protozoa Of Logan City And Vicinity, Robert B. Harrison
A Survey Of Human Intestinal Protozoa Of Logan City And Vicinity, Robert B. Harrison
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
Parasitic protozoa of the intestinal tract of man were first observed by Anthony van Leeuwenhoek (1632-1723), a Dutch microscopist. In the year 1681, while observing his own excrement, Leeuwenhoek discovered and described certain forms of life which he called "animalcules" and which were verified later by workers in protozoology as Giardia lamblia, a protozoan parasite of the intestinal tract. During the period preceding the later part of the 19th century many observations of the parasitic intestinal protozoa of men and lower animals were made and many species were classified. It wasn't, however, until the year 1875 that a protozoan …
A Study Of Subspecific Variation In The Yellow Pocket-Gopher (Geomys Lutescens) In Nebraska, And Of The Geographical And Ecological Distribution Of The Variants, Myron H. Swenk
University of Nebraska State Museum: Mammalogy Papers
The Yellow Pocket-Gopher (Geomys lutescens) was described by Merriam (14) in 1890, as a paler and smaller subspecies of Geomys bursarius, based on "numerous specimens received from the Sand Hills of western Nebraska", and especially upon an adult Cjl type specimen (No. 23595, U. S. N. M.) collected in the sandhills along Birdwood Creek, Lincoln County, Nebraska, May 27, 1889, by A. B. Baker. Although even as late as 1931 Scheffer (17) classified Geomys lutescens as a subspecies of G. bursarius, it is without doubt specifically distinct from G. bursarius. In all of its variations …
Changes In True-Prairie Vegetation During Drought As Determined By List Quadrats, J. E. Weaver, Joseph H. Robertson, Robert L. Fowler
Changes In True-Prairie Vegetation During Drought As Determined By List Quadrats, J. E. Weaver, Joseph H. Robertson, Robert L. Fowler
Papers of John E. Weaver (1884–1956)
The drought of 1934 was not only the most severe on record for the true-prairie association but was also of the earliest inception. On June 8, Kincer ('34) stated that "pastures are the poorest ever known, and the hay crop will be extremely short, regardless of future weather." The stress increased as the summer advanced. Stoddart ('35) tood advantage of these conditions to investigate the relation of osmotic pressure and water content of prairie plants to environmental factors in the vicinity of Lincoln, Nebraska. Simultaneously, Nedrow ('37) was conducting trenching experiments in his study of the efficiency of absorption at …

A Study Of Local Size Variations In The Prairie Pocket-Gopher (Geomys Bursarius), With Description Of A New Subspecies From Nebraska, Myron H. Swenk
University of Nebraska State Museum: Mammalogy Papers
Beginning in the fall of 1913, the writer has continuously been interested in accumulating accurate body measurements, taken in the flesh, of Nebraska pocket-gophers. As a result quite an assemblage of such data has been secured. In the case of Geomys bursarius, the bulk of these data relates to specimens trapped in the vicinity of Lincoln, Lancaster County, involving to date 48 adult and 38 immature males and 50 adult and 65 immature females. Recently these measurements have been tabulated and compared with such measurements of the species as have been recorded in the literature from other parts of …

A Study Of The Variations In The Growth Of Blue Grama Grass From Seed Produced In Various Sections Of The Great Plains Region, Andrew Riegel
A Study Of The Variations In The Growth Of Blue Grama Grass From Seed Produced In Various Sections Of The Great Plains Region, Andrew Riegel
Master's Theses or Doctor of Nursing Practice
During the past 7 years the Great Plains Region, with its "dust bowl", has been the scene of unparalleled activity in the fields of range management and erosion control. The people of this short grass area are extremely conscious of the need for a sound, practical program of conservation that will revegetate the wasted pasture and cultivated land, which will aid materially in preserving the eroding soil. Many problems have arisen as the program of conserving the soil and the vegetation has progressed.
A History Of The Changes In Population Of Certain Mammals In Western Kansas, Floyd L. Carter
A History Of The Changes In Population Of Certain Mammals In Western Kansas, Floyd L. Carter
Master's Theses or Doctor of Nursing Practice
This particular study has been restricted to certain mammals in western Kansas, including some on which there is little information, and others which observers would be most likely to notice in everyday life. For several years the writer has been vitally interested in the animal life in Kansas. Therefore, when the need for a study of western Kansas mammals was presented to him in the summer of 1936, the problem of this study was selected. It is hoped that this report will suggest to ecologists, historians, and others, further studies, including reasons for the changes here-in shown. What have been …
Weather And Plant-Development Data As Determinants Of Grazing Periods On Mountain Range, David F. Costello, Raymond Price
Weather And Plant-Development Data As Determinants Of Grazing Periods On Mountain Range, David F. Costello, Raymond Price
Aspen Bibliography
Fundamental in economical range-resource management is the determination of proper grazing periods. It is of prime importance to be able to establish a date in the spring when the range has produced sufficient feed to keep livestock in thrifty condition, when it is reasonably safe from excessive trampling and packing of the soil, and when the more important key forage plants have attained sufficient development to withstand grazing use. Such opening dates, as well as the time to defer and rotate grazing and to remove livestock from the range, are dependent in part on the prevailing weather conditions and on …

A Study Of The Structure Of Hair As A Means Of Mammal Identification, Earl R. Oyer
A Study Of The Structure Of Hair As A Means Of Mammal Identification, Earl R. Oyer
Master's Theses or Doctor of Nursing Practice
The hair of small and medium sized mammals is often found in the stomachs, feces and pellets of predators , for example in the stomachs and feces of coyotes and in the pellets regurgitated by hawks and owls. These pellets produced by hawks and owls and the feces of mammalian predators are the undigested residue of what these animals have eaten. If the hair from these sources can be identified, then much desirable information concerning the food of predators can be obtained. The purpose of this study has been to determine whether or not such identification is possible.

Anatomy And Histology Of The Digestive Tract Of A Deep-Sea Fish Coelorhynchus Carminatus, Elly M. Jacobsen
Anatomy And Histology Of The Digestive Tract Of A Deep-Sea Fish Coelorhynchus Carminatus, Elly M. Jacobsen
University Studies (University of Nebraska) (1888–1984)
This paper deals with the anatomy and histology of the digestive tube of one of the grenadiers or rat-tails, Coelorhynchus carminatus (Goode), as classified by Jordan & Evermann (1896).1 Many studies on the structure of the digestive tracts of fishes have been made in the past, and pioneer work in the teleost group was done by Valatour in 1861, Pillet in 1894 on the Pleuronectidae, and Gulland in 1898 on the salmon. More recent studies have been made by Greene (1912) on the king salmon, Blake 2 (1930) on the sea bass, and Rogick (1931) on the minnow.
