Breeding Biology Of Cassin’S Finch, Carpodacus Cassinii, F. John Erickson Jr.

All Master's Theses

The present study was undertaken in an effort to increase our understanding of this species' life history, with special reference to the functional significance of delayed plumage development in males. Field studies were conducted throughout the breeding season, and efforts were made to determine whether or not sub-adult males were successful in acquiring mates. In conjunction with consideration of the function of delayed plumage development in males of this species, a general review of this phenomenon has been undertaken in the order Passeriformes.

Social Structure Of Small Mammal Populations At The National Reactor Testing Station, Idaho, R. Lynn Speth

Theses and Dissertations

This investigation examined the social structure of four species of small mammals (Perognathus parvus (Peale), Reithrodontomys megalotis (Baird), Peromyscus maniculatus (Wagner), and Dipodomys ordi (Woodhouse) at the National Reactor Testing Station (NRTS) in Idaho. An understanding of the social structure provides ecological clues concerning the integration of interactions, reproduction, distributions, densities, and diel activities for not only one animal and species, but for a complex of animals interacting with each other.

Review Of Waterfowl In Australia By H. J. Frith, Paul A. Johnsgard

Paul Johnsgard Collection

Our dearth of knowledge concerning Australian waterfowl has, until recently at least, been so severe as to once stimulate Ernst Mayr to write a paper (Emu, 45:229-232, 1946) reminding Australians how little was then known about their native waterfowl. The situation was especially serious in view of the fact that no fewer than six of Australia’s 19 species of indigenous waterfowl represent monotypic genera that are largely or entirely restricted to that continent. Furthermore, these include such phylogenetically significant and taxonomically controversial genera as Anseranas, Cereopsis, Malacorhynthus, and Stictonetta, the last two of which have never been available …

The Fisheries Of Deer Creek Reservoir, Utah, With Special Emphasis On The Yellow Perch (Perca Flavescens Mitchill), Gale R. Lewellen

Theses and Dissertations

This thesis is concerned with the fisheries of Deer Creek Reservoir, Wasatch County, Utah, with special emphasis on the yellow perch. The study period was from May 13 to November 24, 1968. Objectives included the determination of size, age, and food habits of the yellow perch. Parasitic occurrences in the perch population by Ligula intestinalis were also recorded as well as the utilization of the perch by the fishermen. Observations on other species of fish including an analysis of rainbow trout stocking programs were also objectives of this thesis. Data was gathered by means of creel census and fish collection …

Amprolium For Control Of Experimental Coccidiosis In Six- And Twelve-Month-Old Calves, William R. Jolley

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

One hundred Hereford calves were used in 2 experiments, with each experiment lasting approximately 3 months. In the first experiment, 40 yearling heifers were each inoculated with approximately 50,000 E. bovis oocysts daily for 10 days (500,000 oocysts, mixed with water, were poured over the morning dry feed allotment for each pen of 10 animals). Amprolium was given in the feed at 25 mg/kg of body weight daily for 30 days to 20 of the calves; the remaining 20 were not treated. Treatment was started one day before inoculation. The untreated calves had some diarrhea, discharged moderate numbers of oocysts …

The Development Of Eimeria Auburnensis In Cell Culture, Wayne Norris Clark

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

In vitro development of Eimeria auburnensis was studied in cell cultures. The cell types used were established cell lines of adult bovine kidney (Madin-Darby) and embryonic human intestine cells (Int 407); also cell line cultures of embryonic bovine trachea and embryonic bovine spleen cells were used. Monolayer cell cultures were serially propagated in disposable prescription bottles and transferred to Leighton tubes for use in experiments. Coverslips from Leighton tubes cultures inoculated with sporozoites were examined at regular intervals with phase-contrast microscopy for as long as 20 days after inoculation. After examination, coverslips were fixed in Schaudinn's fluid or Stieve's fixative …

Summer Distribution And Food Habits Of Microtus In The Logan Canyon Area, Utah, James B. Monroe

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Field work for the study was conducted in Logan Canyon and the valley at the base of that canyon in Cache County, Utah, during the three summer months of both 1968 and 1969, Microtus pennsylvanicus, found only in the valley, inhabits wet marshy areas. Microtus longicaudus is found in mixed deciduous woods a long the Logan River in the canyon. Microtus richardsoni, which occurs only at the higher elevations, inhabits the subalpine meadows. Microtus montanus inhabits mesic grassy fields in both the valley and Logan Canyon and also inhabits a mixed deciduous woods and tall canary grass ( …

The Social Organization Of Wild Turkeys On The Welder Wildlife Refuge, Texas, Charles Robert Watts

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

This study is of the social organization of the wild turkey (Meleagris gallopavo intermedia Sennett) on the Welder Wildlife Refuge in southern Texas.

The earliest turkey nests hatched in April, with the peak of hatching a month or more later. These poults may remain with their mother until winter. This brood flock, however, often combined with other brood flocks to form composite brood flocks when the poults were a few weeks old. Hens not successful in rearing young combined into broodless flocks.

The juvenile males left the brood flocks in late fall or winter. They remained a distinct unit, …
