Dendrouterina Botauri N. Sp., A Cestode Parasitic In Bitterns, With Remarks On Other Members Of The Genus, Robert L. Rausch

Harold W. Manter Laboratory of Parasitology: Faculty Publications

A single cestode belonging to the genus Dendrouterina Fuhrmann, 1912, was taken from the small intestine of a least bittern, Ixobrychus e. exilis (Gmelin), collected by the writer on May 31, 1945, at Buckeye Lake, Ohio. Considerable difficulty was experienced in obtaining adequate material of this cestocde, although bitterns were collected in Ohio, Michigan, Wisconsin, and Manitoba. A second infected bird, an American bittern, Botaurus l. lentiginosus (Monatgu), was collected on April 24, 1947, at Horicon Marsh, Wisconsin. Three specimens of Dendrouterina were obtained from this bird.
Unfortunately, since refrigeration was not available in the field, the scolices of all …

A New Sciurid Of Blancan Age From Kansas And Nebraska, Claude W. Hibbard

Bulletin of the University of Nebraska State Museum (1924–2023)

The collecting of vetebrate fossils from deposits of Blancan age in Kansas, Nebraska, and Texas during the past twelve years has revealed many interesting forms. Some species have been found to have wide geographic distribution. A large sciurid related to the woodchucks has been recognized from both Kansas and Nebraska and is here described as a new genus and species.

Breeding Efficiency In Dairy Cattle From Artificial Insemination At Various Intervals Before And After Ovulation, George W. Trimberger

Nebraska Agricultural Experiment Station: Historical Research Bulletins

The length of estrus and the time of ovulation were determined for 46 heifers and 86 cows of the Ayrshire, Guernsey, Jersey, and Holstein breeds by testing for end of estrus and ovulation at 2-hour intervals. Services were given by artificial insemination at various intervals before and after ovulation to determine the influence of this factor on the rate of conception. No significant breed or seasonal differences were found for length of estrus and ovulation time after end of estrus among the four dairy breeds represented in the experiment.

Cherry County (Nebraska) Extension: Historical Documents

Educational program of extension work was supported entirely from County Tax funds. The Budget for the coming year was raised to $3,475 from last years budget of $2975. This was very much appreciated, as it will allow a more complete extension service program. This is $25.00 under the $3500 calling allowed by the new bill L. B. 405

The annual meeting was attended by 164 people. The program which was held in the new 4-H building and at the experimental Station, consisted of a business session, four talks on current livestock problems, and a morning and afternoon session of witnessing …

Mule Deer Record For Minnesota, Harvey L. Gunderson

University of Nebraska State Museum: Mammalogy Papers

During the hunting season of 1947, Leonard Nygren shot a deer near Pillager, Cass County, Minnesota. The deer, which weighed 153 pounds dressed, was disqualified in a sportsman's contest because it was not considered a white-tailed deer, according to a newspaper report. The report was investigated and the animal in question was identified as a mule deer, Odocoileus hemionus. This extends the known range of this deer in Minnesota nearly 100 miles to the east. John Jarosz, Museum Preparator, and the writer went to Nygren's place nine miles north of Pillager and measured and skinned the animal which is …

Mima Mounds: A Reply, Victor B. Scheffer

United States Fish and Wildlife Service: Publications

Major Grant believes that gophers behave in one way, and we believe that they behave in another-or we admit that we do not know exactly how they behave. I have plainly stated (1947, PP. 293, 294) that our evidence is indirect; that we have not seen gophers building a giant mound; that we do not know whether mound building is a contemporary or a historic process; and that we do not know whether the stimulus for mound building is a hardpan or a high water table or both.

Our main contentions are that mounds of the Mima type occur only …

Changes In Vegetation And Production Of Forage Resulting From Grazing Lowland Prairie, J. E. Weaver, R. W. Darland

Department of Agronomy and Horticulture: Faculty Publications

When the early settlers came to Iowa, Nebraska, and adjacent territory they entered an almost boundless sea of grass. Throughout the years the prairie has been largely broken for crop production, but even today there still remain considerable tracts of native grassland annually mowed for hay and far greater ones of native pasture (Weaver and Fitzpatrick, '34). Climax grassland when grazed lightly or moderately may retain essentially its natural composition over extremely long periods. It is only when grazing animals are circumscribed in their range by fences and when too large a population is thus confined for too long a …

The Apparent Digestibility Of Prairie Hay Harvested At Three Stages Of Maturity, Arnold Bernard Nelson

Electronic Theses and Dissertations

More land in the United States is used for grazing and hay production than for all other farm crops grown. Well-managed pastures and rangeland have always been recognized as an economical source of feed and recently have commanded much attention as an effective means of conserving soil resources and preventing erosion. In the states if North and South Dakota, Nebraska, Colorado, Wyoming and Montana, about 67 per cent of the total land in farms and ranches is in pasture and hay. Over 60 per cent of the entire area of South Dakota and about 83 per cent of the area …

Carcass Differences In Inbred Lines And Linecrosses Of Swine, Ellis Andine Pierce

Electronic Theses and Dissertations

A great amount of variation in the carcasses from butcher hogs proximal to two hundred and twenty pounds from different lines and breeds has become apparent in recent years. The average hog producer prefers the type of hog that gains quickly and economically and will net the most profit. The average consumer, however, prefers the type of carcass that has a high percentage of lean to fat. Today the dollar value of market hogs is determined more by the amount of finish they are carrying than by the quality of carcass. Since variations do exist in the carcasses from different …

Life Histories Of North American Nuthatches, Wrens, Thrashers And Their Allies: Order Passeriformes, Arthur Cleveland Bent

Papers in Ornithology

An attempt has been made to give as full a life history as possible of the best-known subspecies of each species and to avoid duplication by writing briefly of the others and giving only the characters of the subspecies, its range, and any -habits peculiar to it. In many cases certain habits, probably common to the species as a whole, have been recorded for only one subspecies. Such habits are mentioned under the subspecies on which the observations were made. The distribution gives the range of the species as a whole, with only rough outlines of the ranges of the …

A Study Of The Littoral Marine Isopod Crustacea Of The Dillon Beach Area, Robert James Menzies

University of the Pacific Theses and Dissertations

The primary purpose of this study was to provide accurate diagnoses of the littoral marine isopod crustacea in the Dillon Beach area. Such a purpose involved a much more complete study of the anatomy of the species represented in the fauna than was heretofore performed. Certain anatomical structures deemed by earlier writers as specifically diagnostic are demonstrated to be unreliable and in a great many instances other structures previously neither described or figured by American writers are considered of paramount importance in species identification. The number and magnitude of the changes proposed in this paper as illustrated in outline form …

Trypsin Inhibitor. V. Nutritive Value Of Treated Soybean Oil Meal And Some Characteristics Of The Trypsin Inhibitor In Soybeans, Raymond Borchers, W. E. Ham, R. M. Sandstedt, C. W. Ackerson, R. H. Thayer, F. E. Mussehl

Nebraska Agricultural Experiment Station: Historical Research Bulletins

The marked improvement in the apparent nutritive value of soybean protein after heating has long been recognized. The fundamental cause of this improvement has never been fully understood. Furthermore, commercial soybean oil meal varies considerably in nutritive value although heat treatment is common in most processing plants. Since heating is generally regarded as deleterious to the nutritive quality of protein, the following investigations of various treatments of soybean oil meal are of particular importance in developing a soybean or soybean oil meal of maximum and uniform nutritive value.

A Preliminary Study Of A Physical Basis Of Bird Navigation, Henry L. Yeagley

Papers in Ornithology

The bird navigation theory as presented implies an organ or organs in the bird's physiology which are sensitive to the effect of its motion through the vertical component of the earth's magnetic field and to the effort exerted to overcome the coriolis force, due to the earth's rotation. Both these influences involve a set of lines which together form a navigational gridwork. By correlating its instantaneous land speed with the two above effects, a bird can fly to its home which is a unique point in this gridwork, or to related companion points existing in the gridwork at positions other …

Thinking Of Others At Christmas, Anna M. Wilson

SDSU Extension Circulars

A true gift is a joy to give and a pleasure to receive. Such a gift doesn't just happen, it grows. It takes thought and planning. Then it takes some doing. Gifts made at home will not stretch the purse strings too far, and they can be hand-tailored to the friend. The best gift may not be wrapped in tissue and ribbon-it might be an invitation to a Christmas tea party. Thinking of others will make Christmas the most joyous season of the year-as it should be.

Bakererpes Fragilis N. G., N. Sp., A Cestode From The Nighthawk (Cestoda: Dilepididae), Robert L. Rausch

Harold W. Manter Laboratory of Parasitology: Faculty Publications

The examination of an Eastern Nighthawk (Chordeiles m. minor (Forster)), collected September 25, 1945, at Marion, Ohio, revealed numerous, very small cestodes free in the lumen of the small intestine. About fifty specimens were found, but, because of the delicate strobila of this species, few were entire.
Although these cestodes were very thin and translucent, the preparation of well-stained whole mounts presented unusual difficulty. Best results were obtained with a mixture of Ehrlich's and Delafield's haematoxylin stains. Frontal and transverse serial sections, cut at 10 and 15 μm, were made.
This cestode clearly belongs in the sub-family Dilepidinae, but, …
