Feeding Ecology And Territorial Behavior Of The Yellow Warbler, Merrill J. Frydendall

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

A controversy dating from the appearance of Altum's book, Der Vogel und sein Leben, 1868 (Mayr, 1935) is that of the biological function or functions of the territorial behavior in birds. However, attention was not focused upon this problem until the advent of Howard's book, Territory in Bird Life, published in 1920. In a general review of the problem Hinde (1956) discussed several functions of the territory and presented evidence both for and against their importance. The more important of these presumed functions are: (1) limitation of population density; (2) facilitation of pair formation and maintenance of the …

The Incidence And Life Cycle Of Eimeria Utahensis Sp. N. From Kangaroo Rats Of Northwestern Utah, John V. Ernst

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

A total of 176 kangaroo rats (151 Dipodomys ordii and 25 D. microps) were captured in northwestern Utah and examined for coccidia. Of these 176 rats, four D. ordii (2.6%) and four D. microps (16.0%) were infected with Eimeria utahensis, a new species of coccidia. Little seasonal difference was found in the infection rate of either species. The characteristics of the sporulated oocysts of this species were described. A sporocyst plug was reported for the first time in an eimerian oocyst.

Artificially excysted sporozoites were studied by various methods. Thirty living sporozoites averaged 22.5 𝜇 in length by …

Effects Of Temperature On In Vitro Excystation Of Various Eimeria Species, Larry E. Hibbert

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Cleaned oocysts of Eimeria bovis, E. ellipsoidalis, E. auburnensis, and E. zurnii of cattle, E. ahsata and E. ninakohlyakimovae of sheep, E. bilamellata and E. callospermophili of the ground squirrel, and E. tenella of chickens were pretreated with 50 percent carbon dioxide/50 percent air at temperatures ranging from 29 to 45 C with 2 degree intervals for 4, 6, 8, 10, and 30 hours and treated with bile and trypsin.

The optimum temperature in species of ruminant coccidia was 39 to 41 C. In E. bovis, excystation occurred from 29 to 43 C. At 43 C and above, …

Life Cycles Of Three Species Of Eimeria From The Uinta Ground Squirrel, Spermophilus Armatus, Kenneth S. Todd Jr.

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

A study of the coccidia of the Uinta ground squirrel, Spermophilus (Citellus) armatus, was undertaken to determine the incidence of coccidia in a population of these ground squirrels, the life cycle and pathogenicity of the coccidia, and the host specificity of certain of the species of coccidia found in this and five other species of ground squirrels (S. richardsoni, S. variegatus, S. lateralis, S. columbianus, and S. beecheyi).

Uinta ground squirrels were live trapped and their feces examined to determine the incidence of coccidian infection. Specimens of S. armatus were maintained in the laboratory and given a pure inoculum of …

Notes On Some Mammals From Nebraska, Jerry R. Choate, Hugh H. Genoways

University of Nebraska State Museum: Mammalogy Papers

In the course of field studies in Nebraska, several noteworthy records of mammals have been obtained that add significantly to their known distribution, as shown by Jones (1964) in his "Distribution and taxonomy of mammals of Nebraska." In the following accounts all catalogue numbers refer to specimens deposited in The University of Kansas Museum of Natural History. Parenthetical page references refer to Jones (1964) unless otherwise indicated.

Second Record Of Myotis Volans From North Dakota, Hugh H. Genoways

University of Nebraska State Museum: Mammalogy Papers

The first record of the long-legged myotis, Myotis volans interior, in North Dakota was reported by Jones and Genoways (Trans. Kansas Acad. Sci., 69:89, 1966) on the basis of a single male from 1 mi. S and 1 mi. W Medora, Billings County. On 25 May 1966, nine adult females (KU 106932-40) of this bat were obtained by Donald R. Johnson in Granville, McHenry County. These specimens extend the known geographic distribution of M. v. interior approximately 160 miles to the northeast from the previously reported North Dakotan locality and represent the northeastern most locality of record for the …

Taxonomic Status Of The Brush Mouse, Peromyscus Boylii Cansensis Long, 1961, Jerry R. Choate, Carleton J. Phillips, Hugh H. Genoways

University of Nebraska State Museum: Mammalogy Papers

In the course of a study of mammals from southeastern Kansas and northeastern Oklahoma, the authors have collected specimens of the brush mouse, Peromyscus boylii cansensis Long, from its type locality and also from a place about 16 miles southwest of the type locality. The results of studies of these specimens, and of the holotype and paratypes of the subspecies, are presented and discussed herein.

The Moose In Northeastern Minnesota, Patrick D. Karns

Journal of the Minnesota Academy of Science

The succession of dominant cervids in northeastern Minnesota since settlement has passed from moose and woodland caribou to moose lo white-tailed deer and is now returning to moose. Results of recent studies show high moose densities in some areas are leading lo range deterioration and reduced net productivity. Pneumostrongylus tenuis, a common parasite of white-tailed deer but fatal to moose, is the etiological agent of moose disease. With increases in deer density, such as occurred in the 1920's and 30's, the reports of this disease in moose became more prevalent. Presently, where moose occur on the high deer density areas …

Northern Pike Production In Phalen Pond, Minnesota, James E. Bryan

Journal of the Minnesota Academy of Science

In this study, certain physical, chemical and biological conditions were observed in order to relate them to the development and survival of eggs and young northern pike in a small pond. The spawning period lasted one week and was interrupted by unfavorable weather. Low temperature caused the eggs to develop at a rate slower than the rate other workers have shown to be normal. Many eggs between stages II and Ill appeared to be developing abnormally and were perhaps reacting to an unsuitable environmental condition. Since 90% of all eggs completed development, neither slow nor abnormal development increased the egg …

Evidence For Seasonal Variation In Incidence Of Renal Adenocarcinoma In Rana Pipiens, Robert Gilmore Mckinnell

Journal of the Minnesota Academy of Science

A high incidence of frog renal adenocarcinoma as determined by autopsy in purchased late fall and winter individuals is contrasted to the scarcity of the adenocarcinoma in summer field captured frogs.

Revised Distribution Records Of Some Minnesota Fishes, With Addition Of Two Species To The Faunal List, Gary L. Phillips, James C. Underhill

Journal of the Minnesota Academy of Science

Recent collections of fishes in Minnesota hove resulted in the addition of two species, Moxostoma carinatum (Catostomidae) and Ammocrypta asprella (Percidae), to the state's inland faunal list. Additional information on the distribution of 11 other species (Minytrema melanops, Hybopsis x-punctata, Opsopoeodus emiliae, Dionda nubiloa, Notropis amnis, Notropis texanus, Notropis umbratilis, Pimephales vigilax, Lepomis humilis, Etheostoma asprigene, ond Etheostoma microperca) is presented . Collections in large rivers are responsible for several new distribution records, and further sampling in such habitats should lead to further discoveries.

Studies On The Effects Of Toxic Materials On The Respiration Rate Of Tubificidae, Richard A. Sikora

Masters Theses

A study was made to determine the effect of lead, nickel and pentachlorophenol, at varying pH levels, on the respiration rate of this family of aquatic oligochaetes. Respiration was measured as the ul. of oxygen consumer per mg. of live tissue per hour of exposure.

Worms were found to decrease their rate of respiration in the presence of lead nitrate. This was demonstrated at three pH levels: 6.5, 7.5 and 8.5. It was concluded that this drop was due to the action of lead on the enzymes of the metabolic systems and on the characteristic of lead which stimulates the …

A Study Of The Communities Of Aquatic Macro-Invertebrates Of The Merging Of The Mississippi And Chippewa Rivers, Using A Biplate Substrate Sampler, Robert R. Elbert, Clarence D. Mcnabb

Journal of the Minnesota Academy of Science

Using a biplate substrate sampler, aquatic macro-invertebrates were collected during the fall, winter and spring seasons at the confluence of the Mississippi and Chippewa Rivers along the Minnesota-Wisconsin border. The substrate sampler proved very desirable in pointing out extreme community variations which existed between the two rivers. It was found that the members of a downstream community were a blend of the communities present in upstream tributaries. However, as compared with upstream communities, a shift in dominant organisms occurred. Striking seasonal changes appeared in the invertebrate populations as well as the environment of the rivers. All sampling revealed "clean water" …

A Comparative Osteological Study Of Two Species Of Colubridae: (Pituophis And Thamnophis), Robert E. Bullock, Wilmer W. Tanner

Brigham Young University Science Bulletin, Biological Series

The complete skeletal anatomy of Pituophis catenifer deserticola Stejneger is described in detail. The osteology of this species is compared with that of Thamnophis radix haydeni Kennicott in the following areas: atlas, axis, first thoracic, other thoracic lumbar, anterior caudal, middle caudal, and posterior caudal vertebrae, as well as the skull and hyoid apparatus.

Many structural similarities exist in these two species of colubrids. The more important structures or aspects in which similarities were observed are: (1) the natural division of the vertebral column into regions and subregions, (2) the gross morphology of the various types of vertebrae, (3) the …
