A Study Of The Anatomical Structure Of The 6mm Wall-Eyed Pike, Richard E. Roche May 1942

A Study Of The Anatomical Structure Of The 6mm Wall-Eyed Pike, Richard E. Roche

Bachelors’ Theses

The following is a detailed study of the 6 mm Wall-eyed Pike. The organs and organ systems are presented and discussed in the same serial order that they appear in the embryo beginning at the anterior end and proceeding posteriorly. There has apparently been very little work done on the embryology of the Wall-eyed Pile for the literature contains only one article that is even closely related to this problem. In 1890 Reighard made a general study of the development of the Wall-eyed Pike from the time of fertilization to the fully grown adult. He did not, however, make any …

Phylogenetic Studies On The Blood-Inhabiting Trematodes, Harold Frederick Dieckmann Jan 1941

Phylogenetic Studies On The Blood-Inhabiting Trematodes, Harold Frederick Dieckmann

University of the Pacific Theses and Dissertations

Trematodes belonging to the blood-inhabiting group have long attracted the attention of parasitologists and medical men, especially those trematodos belonging to the family Schistosomidae because throw widely distributed species, Schistosoma Japonicum, S. haematobium, and S. mansoni, are parasitic in man, and in endemic regions are the cause of important human diseases. These schistosomes, with a few exception, have undergone more detailed research than any other trematodes.

Since the discovery of the first digenetic trematode exhibiting sexual dimorphism by Rudolphi (1819), which was named Distoma canaliculatum, and the descriptions of the other blood flukes up until the present time, a vast …

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 Jun 1940

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 Study Of The Skeletal System Of Emys Blanding Turtle, Joseph M. Mosovsky May 1940

A Study Of The Skeletal System Of Emys Blanding Turtle, Joseph M. Mosovsky

Bachelors’ Theses

The turtles have a bony investment or shell, into which the legs, head, and tail maybe drawn. In some turtles there is a hinge on the lower part of the shell that enables the animal to enclose itself more completely. Turtles which have no way of defending themselves other than by their shells have a well developed plastron and carapace for protection, but our vicious friend the snapping turtle whom nature has provided with powerful jaws and muscles has a comparatively small plastron. The marine turtles have the limbs fin-like, indicating their aquatic life. The land turtles have them short …

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 Feb 1940

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 …

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 Aug 1939

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 Jul 1939

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 …

A Study Of The Structure Of Hair As A Means Of Mammal Identification, Earl R. Oyer Feb 1939

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.

Studies In Breaking The Rest Period Of Grass Plants By Treatments With Potassium Thiocyante And In Stimulating Growth With Artificial Light, Harold R. Shepherd May 1938

Studies In Breaking The Rest Period Of Grass Plants By Treatments With Potassium Thiocyante And In Stimulating Growth With Artificial Light, Harold R. Shepherd

Master's Theses or Doctor of Nursing Practice

There has developed a need for a practical means of artificially breaking the rest period and of stimulating the growth of grasses so that sods can be procured early in the fall before freezing weather, brought into the greenhouse, and forced early to make an abundant vegetative growth. This need suggested the study of which this paper is the report, namely to discover whether or not the rest period of native grasses can be broken by treatment with potassium thiocyanate and their growth stimulated by artificial light supplemental to winter daylight.

Bachelors’ Theses

The object of this paper is neither to contribute any new information, nor to criticize any work that has been done on the liver of the frog. The aim is merely to give a brief summary of the gross anatomy, the progress achieved in certain cytological fields, and the function of the liver in digestion and as a dietary factor. In doing this, the paper is intended to show the general trend of research which is apparent in current literature


The Blood Of The Frog, Leonard Gorenstein May 1938

The Blood Of The Frog, Leonard Gorenstein

Bachelors’ Theses

The circulatory system of the vertebrates is one of the most important found in the animal kingdom. The reason being that it carries food, oxygen, and hormones to all parts of the body and also removes all types of waste materials. this system involves a pump-like apparatus, called the heart, to which are attached tube-like vessels called arteries and veins. A liquid called a fluid-tissue circulates in this closed transportation system which is said to be closed in order to distinguish it from a semi-closed or open system in which a sinus or tissue cavity separates certain arteries and veins. …
