Pleistocene Evolution Of The Ohio And Wabash Valleys, William J. Wayne
Pleistocene Evolution Of The Ohio And Wabash Valleys, William J. Wayne
Department of Earth and Atmospheric Sciences: Faculty Publications
Studies of drift thickness and character currently in progress in Indiana indicate changes in drainage that have occurred in Indiana and some adjoining states since the beginning of the Pleistocene epoch. After late Tertiary (Lexington) peneplanation the master-drainage line, the Mahomet-Teays Valley system, became entrenched about 200 feet below its former level before it was ponded by Nebraskan ice and diverted into a new course. During the Parker cycle, which was interrupted by glaciation, the present physiographic features of southern Indiana and their now buried extensions to the north became recognizable. Static rejuvenation then was a major factor in erosion …

A Report On Drosophila Collections In Nebraska, David D. Williams, Dwight D. Miller
A Report On Drosophila Collections In Nebraska, David D. Williams, Dwight D. Miller
Bulletin of the University of Nebraska State Museum
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
Insect Types In The Collections Of The University Of Nebraska State Museum, Martin H. Muma
Bulletin of the University of Nebraska State Museum
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.
