Migratory Bird Regulations 1959-60
United States Fish and Wildlife Service: Publications
Migratory birds, which move across State and National borders, are recognized as an international resource requiring conservation on a continental basis. Protection of migratory birds on the North American Continent is provided for by conventions between the United States and Great Britain (for Canada), concluded August 16, 1916 (39 Stat. 1702), and between the United States and the United Mexican States, concluded February 7, 1936 (50 Stat. 1311). Protection in the United States is provided by the Migratory Bird Treaty Act of July 3,1918, as amended (40 Stat. 755; 16 U. S. C. 703). Birds protected by the Migratory Bird …
Bleak Reports Coming From Waterfowl Breeding Grounds, Ross Leffler
Bleak Reports Coming From Waterfowl Breeding Grounds, Ross Leffler
United States Fish and Wildlife Service: Publications
There is no optimism expressed in the reports from the Flyway Biologists and other observers making surveys on the waterfowl breeding grounds in Canada and the United States. The only bright spot is a report from Fairbanks, Alaska, that the Yukon Flats and other breeding areas in that vicinity are well populated with waterfowl. While this is a heartening sign, only in a small degree does it offset the prospects for poor production in the heart of the continental breeding grounds in the Prairie States and Provinces.
As one observer with many years of experience in the prairies has put …

Comments On Species Recognition With Special Reference To The Wood Duck And The Mandarin Duck, William C. Dilger, Paul A. Johnsgard
Comments On Species Recognition With Special Reference To The Wood Duck And The Mandarin Duck, William C. Dilger, Paul A. Johnsgard
Papers in Ornithology
It is well known that closely related, sympatric species have evolved species-specific features which serve to minimize the possibility of "wrong" choices being made during pair formation. The amount of evolution of such species-specific features is roughly proportional to the deleterious effects of the "wrong" choices made in species recognition. Of course, if upon initial contact, the forms interbreed too freely panmixia will occur and both will eventually lose whatever genetic identity they may have had. On the other hand if, by the time of contact, the forms have incidentally developed differences sufficient to serve automatically as isolating mechanisms from …

The Waterfowl Councils A Conservation Partnership
The Waterfowl Councils A Conservation Partnership
United States Fish and Wildlife Service: Publications
What is a Waterfowl Council?
It's doubtful if many duck hunters know the answer to that question. Yet these Councils are responsible for the planning of many programs that will influence the kind of duck hunting these same sportsmen will have in the future.
Because the activities of the Waterfowl Councils do mean so much to so many people--not only to duck hunters but to the millions of people who get their fun just watching the birds-this circular has been prepared to tell the Council story. Its purpose is to explain the basic waterfowl problem and the current approach to …
Variability In The Electrophoretic Patterns Of Avian Serum Proteins, Charles G. Sibley, Paul A. Johnsgard
Variability In The Electrophoretic Patterns Of Avian Serum Proteins, Charles G. Sibley, Paul A. Johnsgard
Papers in Ornithology
It has been known for more than 50 years that particular proteins characterize every species of plant and animal and that phylogenetic relationships are reflected in protein structure. The first application of this fact to taxonomic studies was by Nuttall ( 1901; 1904) who used the precipitin reaction of immune sera to test degrees of relationship in over 500 species of animals. With refinements in technique have come many more serological studies and the results have justified the statement by Landsteiner (1945) that “chemical differences parallel the variation in structure” and hence are useful in classification.
Habitat Of Red-Backed Vole, Harvey L. Gunderson
Habitat Of Red-Backed Vole, Harvey L. Gunderson
University of Nebraska State Museum: Mammalogy Papers
These data are a part of a study of small mammal populations at Cedar Creek Forest, Anoka County, Minnesota. The live-trapping area of 5.0 acres, with 81 traps spaced 52 feet apart, was in a tamarack-white cedar bog. The study extended over a period of 7 years (1949-1955). Trapping periods of five days (four nights) extended from early May to the first part of October. In all, there were 14,580 trap-nights. A total of 428 voles were marked and weighed; data on 25 dead unmarked individuals are also included.
A frequency index was calculated for each station. This index was …

Grain Sorghum For Growing-Finishing Swine, E. R. Peo, Jr., D. B. Hudman
Grain Sorghum For Growing-Finishing Swine, E. R. Peo, Jr., D. B. Hudman
Department of Animal Science: Faculty Publications
Considerable research has been conducted on the feeding value of grain sorghums for swine. Baker and Reinmiller (1939) observed that for the production of gains, grain sorghums were equal to or better than corn but considerable more feed was required to produce a pound of gain with the sorghums. Loeffel (1957) summarized several Nebraska swine experiments and observed that grain sorghum and corn produced approximately the same average daily gain, but, in general, 10 to 20~o more feed was required per pound of gain with the grain sorghum. Similar results have been reported by Aubel (1950, 1954, 1955, 1956) and …
Field Techniques For Sexing And Aging Game Animals, Donald R. Thompson
Field Techniques For Sexing And Aging Game Animals, Donald R. Thompson
Nebraska Game and Parks Commission: Publications
The purpose of this booklet is to provide a ready field reference for identification, sexing and aging of common game species. It has purposely been kept in simplified form, presenting only those techniques which can commonly be applied in the field and avoiding those which would require special equipment and skills. Untrained personnel should be given demonstrations of the techniques, and thereafter this reference should serve as a reminder. It is not expected that the reference could successfully be used without such demonstration. Certain of the techniques such as cloaca! examination of waterfowl may require considerable practice by the individual. …

Control Of Hog Lice And Mange, Robert Roselle
Control Of Hog Lice And Mange, Robert Roselle
Department of Entomology: Faculty Publications
The hog louse (Haematopinus suis) is the largest species of louse found on domestic animals. It may attain a length of one-quarter of an inch. The body is oval, and the legs terminate in large, dark claws well adapted to cling to hairs. Hog lice are bluish-gray in color. They are found only on hG>gs except in very unusual cases. The eggs or "nits" are glued to the hairs and hatch in 12 to 20 days. Young lice mature in 10 to 12 days. The average life cycle is about 35 days. Lice suck blood from the host, and …
Research Notes: Experimental Infection With Strigoid Cercariae, Glenn L. Hoffman
Research Notes: Experimental Infection With Strigoid Cercariae, Glenn L. Hoffman
United States Fish and Wildlife Service: Publications
During the summers of 1947 and 1948 strigeoid cercariae from Carrol Lake, Wisconsin were collected and identified by the late Dr. F. G. Brooks and turned over to the writer for use in the experimental infection of frog tadpoles and various fish. It was hoped to establish or eliminate these animals as the second intermediate host. One of the 8 tested was found infective for fish, and 1 infected tadpoles. These records do not elucidate the life cycles of these worms, but it is hoped that the work may help in the future study of strigeoid cercariae.

The Experimental Histopathology Of The "Tumor" On The Brain Of The Stickleback Caused By Diplostomum Baeri Eucaliae Hoffman And Hundley, 1957 (Trematoda: Strigeoidea)), Glenn L. Hoffman, James B. Hoyme
United States Fish and Wildlife Service: Publications
The structure of the "tumor" on the brain of the stickleback fish, Eucalia inconstans (Kirtland) caused by Diplostomum baeri eucaliae, has been briefly reported (Hoffman and Hoyme, 1957; Hoffman and Hundley, 1957) and consists of an outgrowth of the columnar epithelium of the choroid plexus which surrounds the metacercariae at the postero-lateral aspect of the optic lobes. The present report deals with the experimental development of the "tumor."
No record of a comparable structure in fish could be found and the reader is referred to our earlier paper (Hoffman and Hundley, 1957) for further introduction, and materials and methods.

Studies On The Life-Cycle Of Ornithodiplostomum Ptychocheilus (Faust) (Trematoda: Strigeoieda) And The "Self Cure" Of Infected Fish*, Glenn L. Hoffman
United States Fish and Wildlife Service: Publications
During the summer of 1956 the following fish of Turtle River (Arvilla), North Dakota were found infected with the Neascus metacercaria of Ornithodiplostomum ptychocheilus (Faust): Northern common shiner (Notropis cornutus frontalis), bigmouth shiner (Notropis d. dorsalis), creek chub (Semotilus a. atromaculatus), fathead (Pimephales p. promelas), and johnny darter (Boleosoma n. nigrum). The cysts were usually very numerous (up to 400 per fish) in the mesenteries of the chub and common shiner; they were also very numerous in the cranial cavity and in the fat bodies behind the eyes of the …

During the summers of 1953, 1954, and 1955, many brook stickleback, Eucalia inconstans, from the English Coulee, a small stream in Grand Forks, were found infected with an unrecorded species of diplostomulum metacercaria; its life cycle has been reported in abstract (Hoffman, 1955). In 1953, 51 (82%) of the 62 sticklebacks examined were infected, but in 1955 a much smaller number was infected; no exact records were kept in 1954 and 1955. The number of diplostomula per fish ranged from 0 to 335. During the summer of 1956 lightly infected stickleback were also found in Turtle River, Kelly's Slough, …
