Foraminiferids Of The Cannonball Formation (Paleocene, Danian) In Western North Dakota, William E. Fenner Jan 1976

Foraminiferids Of The Cannonball Formation (Paleocene, Danian) In Western North Dakota, William E. Fenner

Theses and Dissertations

In 1974 and 1975 about 2800 samples (of which 265 contained foram iniferids) of the Cannonball Formation were collected from 60 water test wells and two oil wells in Adams, Bowman, Burleigh, Divide, Dunn, Grant, Mercer, Morton, Oliver, Sioux, and Ward Counties in western North Dakota. Fifty species of benthonic foraminiferids and four species of planktonic foraminiferids were identified including eight textulariines, two milio lines and 44 rotaliines. Taxa reported for the first time from the Can nonball include: Reophax sp. (2 species), Am:mobaculites expansus Plummer, Spiroplectammina wilcoxensis Cushman and Ponton, Quinqueloculina plummerae Cushman and Todd, Dentalina eocenica Cushman, Lenticulina …

The Glacial Geology Of Mckenzie County, North Dakota, Clark Clark Fulton Jan 1976

The Glacial Geology Of Mckenzie County, North Dakota, Clark Clark Fulton

Theses and Dissertations

Fourteen lithostratigraphic units composed of windblown, glacial, lake, slopewash, and stream sediment were distinguished in McKenzie County, The units were mapped using aerial photographs, topographic maps, and soil maps combi11ed with field e:xaminations of sediment outcrops. Eight of the units have been formally named and described in earlier studies. Four of them, however, have not been a"~ previously named and formally described .a.nu assigned names in this study. Two other units are described, but because of their limited exposure, are not assigned a formal lithostratlgraphic name. The oldest sediment exposed in the county was deposited during the Paleocene and the …

Geology Of The Western Portion Of The Dogtooth Pluton, Lake Of The Woods Region, Southwestern Ontario, Richard H. Pilatzke Jan 1976

Geology Of The Western Portion Of The Dogtooth Pluton, Lake Of The Woods Region, Southwestern Ontario, Richard H. Pilatzke

Theses and Dissertations

A 10 km2 portion of a subsolvus, syntectonic or posttectonic grano dioritic intrusion located about 16 km east of Kenora, Ontario was extensively sampled for study by petrographic modal analysis and trend surface analysis. The Dogtooth pluton, the main intrusive body sampled, is part of a granitic batholith known as the Dryberry dome, which is interpreted to have been intruded into supracrustal volcanic and sedi mentary rocks about 2480 million years ago during the Kenoran Orogeny. The Longbow pluton, which was also sampled, occurs at the west margin of the Dryberry dome in contact with the supracrustal rocks to the …

Topological Properties Of The Real Numbers Object In A Topos, Lawrence Stout Dec 1975

Topological Properties Of The Real Numbers Object In A Topos, Lawrence Stout

Lawrence N. Stout

In his presentation at the categories Session at Oberwolfach in 1973, Tierney defined the continuous reals for a topos with a natural numbers object (he called them Dedekind reals). Mulvey studied the algebraic properties of the object of continuous reals and proved that the construction gave the sheaf of germs of continuous functions from X to R in the spatial topos Sh( X). This paper presents the results of the study of the topological properties of the continuous reals with an emphasis on similarities with classical mathematics and applications to familiar concepts rephrased in topos terms.

Bats, Biology, And Control, Stephen P. Kincaid Dec 1975

Bats, Biology, And Control, Stephen P. Kincaid

Great Plains Wildlife Damage Control Workshop Proceedings

Although bats are not commonly thought of as major members of the animal kingdom, they are one of the most numerous of land vertebrates. Bats are thought to have originated in the Old Wordl Tropics and are now almost world-wide in distribution. Bats make up the order Chiroptera, and they are closely related to the hedgehog, shrew and mole.

The Coyote As A Game Animal, Edward L. Kozicky Dec 1975

The Coyote As A Game Animal, Edward L. Kozicky

Great Plains Wildlife Damage Control Workshop Proceedings

Coyote hunting is a very special challenge. Even though coyotes may be abundant in an area, that doesn't mean that they're easy to bag with a rifle. However, I happen to enjoy coyote calling to the point where the shooting is almost anti-climax. Others like to hunt coyotes with either sight or trail hounds, to pursue coyotes with all-terrain vehicles, and to spot coyotes while driving through the country.

Bird Control, Glen Orr Dec 1975

Bird Control, Glen Orr

Great Plains Wildlife Damage Control Workshop Proceedings

We started our program in 1967 primarily because of an economic problem in the downtown area of Wichita. We had about eight square blocks of businesses which were not getting any business because people didn't dare go downtown in the evening unless they wore their rain hats and rain gear, and I mean this literally.

Prairie Dog Control, A. Orville Sandall

Great Plains Wildlife Damage Control Workshop Proceedings

Before poisons were taken from the market, I had about fifteen years experience working for the Fish and Wildlife Service doing prairie dog control work. Most of this work was done for private landowners and supervising work crews for the Forest Service and B&A.

Snake Control, Steve Thompson Dec 1975

Snake Control, Steve Thompson

Great Plains Wildlife Damage Control Workshop Proceedings

Whether wild animals are benificial or injurious depends on the time and the place. It seems that no one likes to have venomous or even harmless snakes in his corral, in his yard, or even on his doorstep; but every spring and fall many people are confronted with this situation. Many requests are recieved each year on how to rid an area of these unwanted reptiles.

An Overview Of Problem Bird Management - Rural And Urban, Joseph L. Guarino Dec 1975

An Overview Of Problem Bird Management - Rural And Urban, Joseph L. Guarino

Great Plains Wildlife Damage Control Workshop Proceedings

The economic impact of birds on agricultural crops in the U.S. is quite substantial -- perhaps as much as $100 million dollars. Methods for reducing this damage can be categorized as biological, mechanical, and chemical. The chemical approach appears to have the most potential. An avian repellent, methiocarb, has proven to be effective for reducing damage by a variety of species of birds to many sprouting and ripening crops and fruit. An avian chemical frightening agent, 4-aminopyridine (Avitrol), if federall registered for use for protecting ripening field corn and sweet corn and was shown to be effective for reducing damage …

Bird Control, George C. Halazon Dec 1975

Bird Control, George C. Halazon

Great Plains Wildlife Damage Control Workshop Proceedings

We did a little work with pigeon sterilants six years ago. We didn't really have too much luck on bird control on pigeons because of the life of the pigeon. In other words we couldn't do it fast enough to satisfy the public because of the relatively large numbers of years required before the bird dies.

Controlling Mole Damage, F. Robert Henderson Dec 1975

Controlling Mole Damage, F. Robert Henderson

Great Plains Wildlife Damage Control Workshop Proceedings

The kind of mole found in Kansas is the eastern mole, Scalopus aquaticus. Moles are small, mouse-sized mammals adapted to living underground. They are characterized by enlarged forefeet with long claws, stout necks and powerful shoulders which make them capable burrowers. Unlike those of mice and shrews, the noses and forefeet of moles are pink and hairless.

Progress In Coyote Hunting Depredations Research, Samuel B. Linhart Dec 1975

Progress In Coyote Hunting Depredations Research, Samuel B. Linhart

Great Plains Wildlife Damage Control Workshop Proceedings

Coyote depredations control research from the end of World War II to about 1960 was characterized by low levels of funding, a minimum of research facilities, an emphasis on lethal agents, few legislative restrictions, a lack of public interest, and little concern for the environment. Establishment of the Leopold Committee (1964) and Cain Committee (1971) were evidence of a growing public concern and awareness of the coyote-livestock problem.

Control Of White-Tailed Deer In Field And Orchard, Forrest D. Loomis, Ronald Ogden Dec 1975

Control Of White-Tailed Deer In Field And Orchard, Forrest D. Loomis, Ronald Ogden

Great Plains Wildlife Damage Control Workshop Proceedings

As deer populations increase in most areas of the mid-west, and deer habitat is constantly shrinking because of man's activities, damage done to crops, orchards, and other plantings is increasing. No new or revolutionary control or repellent has been perfected to alleviate this complex problem. Annual hunting still offers the best and cheapest method of control.

Beaver Damage Control, James E. Miller Dec 1975

Beaver Damage Control, James E. Miller

Great Plains Wildlife Damage Control Workshop Proceedings

The beaver (Castor canadensis), our largest North American rodent, is praised by many as being a natural conservationist; however, to others he is a destructive nuisance and pest. In many chronicles, the beaver is lauded to be one of the resources that speeded up the settling of our Great Northwest Territory. Certainly, such explorers as Lewis and Clark depended greatly upon the beaver hide for revenue as well as varter.

Woodchucks And Their Control, Robert H. Smith Dec 1975

Woodchucks And Their Control, Robert H. Smith

Great Plains Wildlife Damage Control Workshop Proceedings

Woodchucks, or groundhogs, (Marmota monax) aer found in the eastern edge of the Great Plains. The first part of the scientific name, Marmota, is the Latin word for "marmot," the name given to the European marmot or the North American marmot which are close relatives of the woodchuck. The last part, monax, is an American Indian name for this rodent and means "the digger"; it alludes to the woodchuck's habit of excavating burrows.

Raccoon Damage Control, W. Alan Wentz Dec 1975

Raccoon Damage Control, W. Alan Wentz

Great Plains Wildlife Damage Control Workshop Proceedings

Raccoons are found throughout the United States, and in most cases they are expanding their range into previously unoccupied habitats. Raccoons are often water-associated, but in the Great Plains they often occur a considerable distance from the water. In the Great Plains states, the expansion of agriculture has apparently allowed raccoons to move westward and northward. It is possible that the availability of old homesteads, buildings, haystacks, dumps, and towns has been instrumental in allowing raccoons to survive the winter.
