The Use Of Tree Rings To Date Beaver Colonies, J. Benton Kettleson

Journal of the Minnesota Academy of Science

In 1946, I began the periodic observation of several beaver colonies located near my family's summer cabin, in Crow Wing Co., central Minnesota. From 1953 to 1956, a detailed study of the colonies was conducted as a Junior Academy of Science project. During this period, several new colonies were established and many of the older ones abandoned. A study of aerial photographs, followed by a ground check on foot or by canoe, turned up many other beaver colonies, some active at the time of discovery and many apparently long deserted.

In searching for a method of ascertaining when these workings …

The Physiological Effects Of Strychnine And Electric Stimuli On Cyclops, Ralph J. Fricke

Journal of the Minnesota Academy of Science

Cyclops, the intermediate hosts of parasites of higher animal~, particularly some tapeworms of fish, waterfowl, and some mammals is a comparatively simply crustacean. From the following it should become apparent that the Cyclops is, in fact, very complex, exhibiting physiological reactions similar to those produced in the mammal. This study will include certain observations of the physiological effects of strychnine and electric stimuli on Cyclops. The animal lacks a heart. Body fluid is circulated as a result of the rhythmic movements of its gut. For the experiments a clone of the species Eueyclops agilis was established. In a clone, all …

An Investigation Of Possible Commensalism In Red Squirrels, Yellow-Bellied Sapsuckers, And Humming-Birds At The Lake Itasca Biological Station, John C. Coulter

Journal of the Minnesota Academy of Science

This is an investigation of a relationship noted at the Lake Itasca Biological Station. It was noted that the Red Squirrel, Tamiasciurus hudsonicus, in some locations spent a considerable amount of time lapping sap from the rows of holes drilled in the White Birch, Betula papyrifera, by the Yellow-bellied Sapsuckers, Sphyropious varius varius (L.). After the invasion of the red squirrel the sapsuckers and the Ruby-throated Hummingbird, Archilochus colubris (L.) continued to utilize the same food supply as well as a considerably number of insects. The two general objectives of this endeavor were then to investigate some of the related …

The Biology Of Karyolysus Dilloni N. Sp. From Rana Aurora Draytoni, Wayne Aldo Sorsoli

University of the Pacific Theses and Dissertations

While investigating various Amphibia of Central California for blood inhabiting parasites, the writer found a parasite in the blood of the Rod-legged Frog (Rana aurora draytoni) which exhibited the characteristics of Karyolysus, yet was different from any described; this same parasite had been previously observed by Dr. D. L. Lerhmann, Associate Professor of Zoology, University of the Pacific. In order to increase the knowledge of this form, further investigations were undertaken.

The first step was to determine the life cycle in the vertebrate host and, if possible, to find the invertebrate host and to elaborate the developmental stages in the …

Treatment Of Experimental Bovine Coccidiosis With Nitrofurazone And Sulfamethazine, Donald L. Ferguson

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Coccidiosis in cattle is caused by microscopic, one-celled parasites known as coccidia (genus Eimeria). It is a common disease that weakens or kills calves or older cattle, with greater loses generally occurring in young animals. Eleven species have been reported in cattle in this country (1). At least two species, Eimeria bovis and E. zurnii, are known to be pathogenic to cattle (9).

A Study Of The Parasites From Rainbow Trout Of A Commercial Fish Farm In Cache Valley, Utah, Kenneth L. Jones

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

During the biennial period July 1, 1956 to June 30, 1958 the 12 state fish hatcheries in Utah produced and stocked in the waters of the state 20,092,902 fish weighing a total of 1,528,787 pounds, at a cost varying between 69 and 75 cents per pound. The cost figure depends upon what expenditures are included (Don Andriano, 1960). A substantial mortality occurs at the fish hatcheries in the state of Utah. The determination of the cause of any given loss is complicated by a number of factors. This is especially true of losses which may be due secondarily to parasites …

Blood Changes In Calves Experimentally Infected With Haemonchus Placei And Ostertagia Ostertagi, Darrell J. Graff

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Parasitic diseases of livestock have long been a subject of considerable interest. Great economic losses are inflicted each year on our growing livestock industry. If these parasitic diseases proceed undetected or untreated the hosts may suffer retardation in weight gain or succumb.

Malaysian Parasites Xxxv-Xlix, W. W. Macdonald

Harold W. Manter Laboratory of Parasitology: Faculty Publications

This is the third Study of the series from this Institute on the external and internal parasites and the biting insects of the Malaysian region. The earlier two volumes were planned and edited by Dr. J.R. Audy, and on his departure from Malaya in the middle of 1959 Mr. W. W. Macdonald continued the work which had been begun and collated and edited the papers in this present Study.

In the two previous volumes (Study No. 26, 1954 and No. 28, 1957) the emphasis was on the taxonomy of Trombiculid mites. In the present volume the emphasis has changed, and …

Observations On The Biology Of Schistocerca Venusta, David Allyn King

University of the Pacific Theses and Dissertations

Statement Qf the problem. The green valley grasshopper, Schistoceroa venusta Scudder, is one of the most common grasshoppers to be found in the San Joaquin Valley and environs. Despite the fact that the insect is commonplace, very little work has been done on its biology. It was the purpose of this study, therefore, to learn by field and laboratory observations of the life cycle and habits of Schistoceroa venusta.

Opecoelid Trematodes From California Including A New Species, Opecoelus Nobelei, Amal Chandra Banerjee

University of the Pacific Theses and Dissertations

The aim of this investigation was to study some of the digenetic trematodes of marine fishes from Monterey Bay, with special reference to the genus Opecoelus family Opecoelidae Ozaki 1925. Extensive work on this family has been done by Dr. D. Yaiuaguti and his colleagues in Japan. After the Allan Hancock Pacific expeditions to the Galapagos Islands in 1934. Dr. H. W. Menter described a few new species from the Galapagos and some Lexicon Islands in 1940. The same author reported a new species from La Jolla, California in 1951; but until now, no further observations have been made on …

The Effect Of Temperature On The Growth Rates Of Several California Frogs, Donald Avila Villeneuve

University of the Pacific Theses and Dissertations

To date the majority of the work on the ecological significance of embryonic temperature relationships has been with Eastern Frongs. The writer is aware of only two papers describing work of this nature with California frogs: Schechtmann and Oleson (1941) working with temperature tolerance in embryos of Hyla regilla, and the work of Zweifel (1955) on the Rana boylei species group.

For this reason it seemed desireable to study the effect of temperature on the growth rates of some frogs native to California and, since work of this nature has been done with the eastern Rana catesbeiana by Moore (1942b), …

Some Hemiurid Trematodes Of Marine Fishes Of California, Fuad Michael Nahhas

University of the Pacific Theses and Dissertations

The following seven species of hemiurid trematodes, some with new host records, are reported in this study: Dissosaccus laevis, Genolinea laticauda, Lecithaster salmonis, Parahemiurus merus, Sterrhurus exodicus, Sterrhurus monticelli and Tubulovesicula lindbergi. Dissosaocus laeyis and Sterrhurus monticelli are reported for the first time from the West Coast of North America.

Genolinea oncorhynohi Adams and Margolis 1958 is placed in synonymy with Genolinea laticauda Manter 1925. Keys for Genolinea and Tubulovesicula species, modified from Manter (1954) are included. Two tables, one summarizing the hemiurids reported from the West Coast of North America, the other a summary of hemiurids from Monterey Bay, …

Behavior Of The Red-Footed Booby (Sulasula) In British Honduras, Jared Verner

LSU Historical Dissertations and Theses

During three months of the breeding season in a colony of 3500 Red-footed Boobies (Sula sula) on 45½-acre Half Moon Caye, fifty miles east of Belize, British Honduras, that species’ little-known breeding activities were investigated. Feeding flights of boobies began leaving the caye before daylight and returned in the evening until after dark. Wind direction and velocity notably affected the mode of the birds’ departure but little affected their direction. Average flight-unit size was 2.41 birds. Contrary to published accounts, the boobies were able to take flight from the ground.
