A Report On Drosophila Collections In Nebraska, David D. Williams, Dwight D. Miller Jan 1952

A Report On Drosophila Collections In Nebraska, David D. Williams, Dwight D. Miller

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

Until rather recently little has been known of the Drosophila species of Nebraska. Sturtevant (1921) lists Nebraska as one of seven states from which no Drosophila had been reported. Patterson and Wagner (1943) show that collections of Drosophila pseudoobscura had been made in the vicinities of Scottsbluff and Kearney, but no other Drosophila species are reported from Nebraska in their publication.


Insect Types In The Collections Of The University Of Nebraska State Museum, Martin H. Muma Jan 1952

Insect Types In The Collections Of The University Of Nebraska State Museum, Martin H. Muma

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

In 1948 the insect collections at the University of Nebraska State Museum were placed in the care of the author. Prior to that date curatorial duties were assumed or assigned to full time teaching or research staff members. As would be expected under the latter circumstances, the organization of study material and types was neglected in many families and genera. Since 1948 type material, because of its intrinsic value, has received considerable attention. All primary and representative secondary types have been assembled in three museum cases and one slide cabinet for curatorial and study convenience.


The Red Cloud Sand And Gravel, A New Pleistocene Formation In Nebraska, C. Bertrand Schultz, Eugene C. Reed, A. L. Lugn Nov 1951

The Red Cloud Sand And Gravel, A New Pleistocene Formation In Nebraska, C. Bertrand Schultz, Eugene C. Reed, A. L. Lugn

Conservation and Survey Division: Faculty and Staff Publications

Recent studies of the stratigraphy and paleontology of the Pleistocene of Nebraska have resulted in additional data that require further clarification and partial revision of the Grand Island sand and gravel formation (1,2) in order that there may be no condusion as the results of varying usage of the term.

A Graphic Résumé Of The Pleistocene Of Nebraska (With Notes On The Fossil Mammalian Remains), C. Bertrand Schultz, Gilbert C. Lueninghoener, W. D. Frankforter

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

I T SEEMS desirable at this time to present a graphic resume of the Nebraska Pleistocene, together with a summary of the stratigraphic sequences of the fossil vertebrates. This report is based on data taken from various publications' in addition to information gathered by the present writers during the past fifteen or more field seasons. Intensive work has been done in the past five years in connection with recovery of paleontological material in the areas where government dams are under construction (Schultz, Lueninghoener, and Frankforter, 1948; Schultz and Frankforter, 1948; Holder and Wike, 1949). The information in the present paper …


Progress Report: Chemical Quality Of The Surface Waters In The Loup River Basin, Nebraska, John G. Connor Jun 1951

Progress Report: Chemical Quality Of The Surface Waters In The Loup River Basin, Nebraska, John G. Connor

United States Geological Survey: Publications

The Loup River and its tributaries transport moderate amounts of siliceous minerals from the sand hills region of north-central Nebraska to the Platte River near Columbus, Nebr. Predominant chemical characteristics of these waters are a high percentage of silica, moderate hardness, and a low percentage of sodium. The composition of the Loup River water is influenced by the geologic formations through which ground water, a major contributor to the flows of the Loup River branches, has percolated. Investigation of water quality at or near proposed dam sites in the Loup River basin indicates that if soil and drainage conditions are …

An Annotated List Of The Orthoptera Of Nebraska Part I The Blattidae, Mantidae And Phasmidae, Harold A. Hauke Jan 1949

An Annotated List Of The Orthoptera Of Nebraska Part I The Blattidae, Mantidae And Phasmidae, Harold A. Hauke

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

This paper is the first of a series on the Orthoptera of Nebraska. In 1932, while a graduate student at the University of Nebraska, the author began a taxonomic study of the Orthoptera, the result of which was an unpublished List of the Othoptera of Nebraska. The list has been studied and revised.


Preliminary Geomorphological Studies Of The Lime Creek Area & Preliminary Report On The Lime Creek Sites: New Evidence Of Early Man In Southwestern Nebraska, C. Bertrand Schultz, Gilbert C. Lueninghuener, W. D. Frankforter Nov 1948

Preliminary Geomorphological Studies Of The Lime Creek Area & Preliminary Report On The Lime Creek Sites: New Evidence Of Early Man In Southwestern Nebraska, C. Bertrand Schultz, Gilbert C. Lueninghuener, W. D. Frankforter

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

PALEONTOLOGICAL and archaeological discoveries were made near Cambridge, Nebraska, by the University of Nebraska State Museum field party in the spring of 1947 (Schultz and Frankforter, 1948, pp. 279-280) . Fossils and artifacts were found in situ at the base of a fifty-foot terrace on Lime Creek (University of Nebraska State Museum Localities Ft-41 and Ft-42) and on Medicine Creek just below the mouth of Lime Creek (Ft-50). Lime Creek is located (Fig. 1) in southwestern Nebraska in the southeastern part of Frontier County. It is a tributary of Medicine Creek which in turn is a tributary to the Republican …

A New Sciurid Of Blancan Age From Kansas And Nebraska, Claude W. Hibbard Jan 1948

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.

Petrology Of The Upper Marietta And Hundred Sandstones In Southeastern Ohio, Wayne Dudley Martin Jan 1948

Petrology Of The Upper Marietta And Hundred Sandstones In Southeastern Ohio, Wayne Dudley Martin

Graduate Theses, Dissertations, and Problem Reports (ETD)

A petrographic study was made of two Lower Permian (Dunkard Series) sandstones in southeastern Ohio. The sandstone members with which the investigation was concerned are the Upper Marietta sandstone and the Hundred sandstone. The study was made in order to determine the origin of the sandstones and the practicability of applying geologic methods to the grindstone industry. The results of the study indicate that although some of the constituents of these sandstones were derived from igneous and sedimentary source rocks, a relatively large amount of material was derived from metamorphic rocks. The detritus was transported from the east and deposited …


The Post-Kansan Geologic History Of The Lower Platte Valley Area, Gilbert Carl Lueninghoener Sep 1947

The Post-Kansan Geologic History Of The Lower Platte Valley Area, Gilbert Carl Lueninghoener

University Studies (University of Nebraska) (1888–1984)

This investigation is essentially a geomorphological study of the lower Platte River Valley area in eastern Nebraska. The area comprises Saunders, Dodge, Washington, Douglas, Sarpy, and Cass counties. The area defined above is one of the most critically located of any for the study of the post-Kansan history of the lower Platte River Valley. It lies between the older till (Nebraskan and Kansan) borders to the west and the younger till (Illinoian, Iowan, and Wisconsin) borders to the east. Physiographic changes have therefore transpired in a strictly post-Kansan periglacial region. The Kansan till is the youngest in the area. The …

The Goss Lemming Mouse, Synaptomys Cooperi Gossii (Goues), In Nebraska, Edson Fichter, Merle F. Hansen Jan 1947

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 Dec 1946

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 …
