Phospholipids Of Thiobacillus Thiooxidans, J. M. Shively, A. A. Benson

School of Biological Sciences: Faculty Publications

Cells and spent growth media from sulfur- and thiosulfate-grown cultures of Thiobacillus thiooxidans were analyzed. The phosphatides were examined by thinlayer chromatography, and the products of their hydrolysis by hydrochloric acid and methanolic potassium hydroxide were separated by paper chromatography. The phospholipids in both cells and spent growth media were identified as phosphatidyl ethanolamine, phosphatidyl N-monomethylethanolamine, phosphatidyl glycerol, and diphosphatidyl glycerol. These comprised about 97% of the total lipid phosphorus. Lyso-phosphatidyl-N-monomethylethanolamine and lysophosphatidylglycerol accounted for the remaining 3%. The percentage of the total lipid phosphorus accounted for by each phospholipid depended on the age of the culture.

Sympatry Changes And Hybridization Incidence In Mallards And Black Ducks, Paul A. Johnsgard

Papers in Ornithology

Changes in general fall and winter distributions of Mallards and Black Ducks over the past century have resulted in markedly increased sympatric contact during pair formation between these two forms, and have been responsible for increased opportunities for hybridization. Bureau of Sport Fisheries and Wildlife records of hybrids from 34 states indicate a minimal current hybridization rate that is about 4% of the frequency expected on the basis of mating according to mathematical probabilities of chance contact. Thus, hybridization is most frequent where both forms are almost equally abundant, indicating that no reinforcement of differences reducing hybridization in the primary …

Ontogeny And Anatomy Of The Flower Of Limnocharis Flava (Butomaceae), Robert B. Kaul

School of Biological Sciences: Faculty Publications

The flowers of Limnocharis flava (L.) Buch. are borne in an indeterminate umbel and each consists of three sepals, three yellow petals, and about 18 carpels surrounded by numerous stamens and staminodia. The androecium is centrifugally developed, and the last-formed members are staminodial; it is supplied by branching vascular systems. Carpels arise almost simultaneously, and a prominent residual floral apex remains. The carpels are partially conduplicately closed and are also primitive in possessing laminar placentation and in lacking differentiation of a style. The gynoecium is essentially apocarpous, but there are slight fusions of adjacent carpels near their ventral margins where …

On The Ecology And Distribution Of Echinococcus Spp. (Cestoda: Taeniidae) And Characteristics Of Their Development In The Intermediate Host, Robert L. Rausch

Harold W. Manter Laboratory of Parasitology: Faculty Publications

Echinococcus granulosus (Batsch, 1786) and E. multilocularis Leuckart, 1863 [syn. Alveococcus multilocularis (Leuckart, 1863) Abuladze, 1960] are distinguished by well defined biological and developmental characteristics. Obligatory predator-prey relationships of the hosts segregate the two species ecologically under natural conditions. The larval stage of E. granulosus develops slowly in long-lived ungulates, while that of E. multilocularis becomes infective within a few months in intermediate hosts (rodents) having a life expectancy of less than a year.

Existing parasite-host relationships of these cestodes had become established at least as early as late Pleistocene time, and two biologically distinct forms of E. granulosus can …

Theory Of Rbe For Heavy Ion Bombardment Of Dry Enzymes And Viruses, J. J. Butts, Robert Katz

Robert Katz Publications

The response of dry enzymes and viruses to heavy ion bombardment may be predicted from their response to γ-irradiation (and no further knowledge of their size and structure). The molecules are approximated as point particles whose response to ionization is the same for heavy ion bombardment as for γ-rays. From the δ-ray distribution formula and an extrapolated range-energy relation for electrons, the radial distribution of secondary ionization energy may be found. Under this dosage distribution the inactivation probability may be found as a function of radial distance from the ion's path, and then may be integrated over all space to …

New Records Of The Pigmy Shrew Microsorex Hoyi (Baird) In Alaska, Robert L. Rausch

Harold W. Manter Laboratory of Parasitology: Faculty Publications

The results of extensive trapping (ca. 7000 small mammals from the Alaskan mainland) indicate that the pigmy shrew, Microsorex hoyi (Baird), is a comparatively rare mammal in Alaska. From January, 1949, to the present, my co-workers and I have collected only seven specimens. These few animals considerably extend the known geographic range of M. hoyi in Alaska.

Endangered And Threatened Wildlife And Plants: Proposed Endangered Status For The American Burying Beetle

Endangered Species Bulletin

The Service proposes to determine endangered status for the American burying beetle (Nicrophorus americanus) and thereby provide the species protection under the Endangered Species Act of 1973, as amended. Once widely distributed throughout eastern North America, this species has disappeared from most of its former range. Two known populations currently exist, one in eastern Oklahoma and the other on an island off the coast of New England. Despite extensive efforts to locate additional populations, only two specimens have been found elsewhere in more than 10 years. The cause of the species’ decline is unknown. Critical habitat is not …

Mosquitoes Of The Cheyenne Bottoms Waterfowl Management Area, Barton County, Kansas, John J. Janovy Jr.

John J. Janovy, Jr. Publications

Studies of the local biology of eleven species of mosquitoes in a prairie marsh in central Kansas revealed that "floodwater" species (Aedes dorsalis, A. nigromaculis, A. sollicitans, A. vexans, Psorophora ciliata, P. cyanescens) formed a major portion of the total mosquito population and were the principal pests after early June. Culex tarsalis was the most numerous single species and was captured in large numbers even during the hot, dry period from mid-July to late August. Culiseta inornata was plentiful in early spring and fall, but virtually absent from late May to mid-September. Culex pipiens, Orthopodomyia signijera, and …

Bird Control Methods And Devices--Comments Of The National Pest Control Association, Philip J. Spear

Bird Control Seminars Proceedings

It may be useful to review some of the considerations that go into recommendations concerning bird management. Later I will make some comments concerning specific methods and devices being used in or promoted for bird control work regardless of whether or not they are new. Members of the National Pest Control Association provide a variety of services, such as fumigation, termite control and general pest control which includes rodent control. There are eight such categories listed in our roster, but only one member in five provides every service listed. Bird control is a rather recent development and is the newest …

Blackbird Flock Behavior In Corn, A Theoretical Model (With Session Discussion), M. I. Dyer

Bird Control Seminars Proceedings

I realized this past winter that redwings form the base for an international problem, and so I went down to see Jim Caslick in Florida. Unfortunately, I picked the wrong season. I misjudged the weather for when I went down in May to get experimental birds it was pretty hot. Next year I'll be a bit more careful and go down during the winter time. I want to discuss something a bit different but still in line with crop damage by red-winged blackbirds. I want to relate the damage assessment that we're making in agricultural corn to bird behavior. We've …

Agricultural Bird Problems In The West, Donald Balser

Bird Control Seminars Proceedings

First, I'd like to qualify geographically, the area where most of our work is done and problems occur. It is primarily in the Rocky Mountain states and the west coast. While the area of the Denver Wildlife Research Center's responsibility covers the states west of the Mississippi River; the only area on the plains where our personnel have conducted intensive studies outside of Colorado is in South Dakota. The major bird problems in grain crops in the west are primarily caused by blackbirds excepting, of course, waterfowl depredations. It's difficult to rank the principal crops according to seriousness of losses. …

Ecological Control Of Bird Hazard To Aircraft, V. E. F. Solman

Bird Control Seminars Proceedings

The Canadian Wildlife Service has had twenty-five years experience with the problem caused by bird contacts with aircraft. I experienced my first bird strike, while flying as an observer on a waterfowl survey in August, 1940. Officers of the Service investigated bird problems at airports at Yarmouth, Nova Scotia, and Cartierville, Quebec, in the late 1940's. Those incidents involving gulls and low speed piston-engined aircraft caused minor damage to the aircraft but considerable disturbance to the operators. As aircraft speeds increased and airports became more numerous and busier the problem increased in extent and complexity. By 1960 it was apparent …

Records Of Bats From Western North Dakota, J. Knox Jones Jr., Hugh H. Genoways

University of Nebraska State Museum: Mammalogy Papers

From June 16 to 19 and again from June 24 to 29, 1965, a field party from the Museum of Natural History of The University of Kansas collected mammals along the Little Missouri River at a place 1 mi. S and 1 mi. W Medora, Billings Co., North Dakota. Among the specimens collected were representatives of five kinds of bats, including one species unreported from North Dakota, a subspecies unrecorded from there, and two species known previously from the state by a single specimen each.

Handbook Of Nebraska Trees: A Guide To The Native And Most Important Introduced Species (Revised 1951), Raymond J. Pool

School of Natural Resources: Faculty Publications

Nebraska is not to be classified as a forested state since less than 3 per cent of the area of the state is covered by natural timber. However our native forest trees are numerous as to different kinds and their distribution in the state is characterized by many interesting facts. The every-day life of our people is not so commonly associated with trees as is that of peoples in the more wooded states where lumbering and the wood-working industries are very important occupations because of the proximity of great forests of coniferous or broadleaved trees. The people of Nebraska use …

Epidemiology Of Plasmodium Hexamerium Huff, 1935, In Meadowlarks And Starlings Of The Cheyenne Bottoms, Barton County, Kansas, John J. Janovy Jr.

John J. Janovy, Jr. Publications

A 2-year epidemiological study of Plasmodium hexamerium in meadowlarks and starlings of the Cheyenne Bottoms Waterfowl Management Area, Barton County, Kansas, revealed that seasonal infection incidence varied significantly in the meadowlark, being highest in the early spring and lowest in the winter, but did not vary significantly in the starling. Both host species became infected at an early age, the meadowlark in the nest and the starling soon after leaving it. In concurrent vector studies: (1) Culex tarsalis was infected with P. hexamerium in the laboratory; (2) C. tarsalis, Aedes nigromaculis, and A. sollicitans were exceedingly abundant and fed …

Nesting Birds Of The Crescent Lake National Wildlife Refuge, Roger S. Sharpe, Raphael Richard Payne

Nebraska Bird Review

The Crescent Lake National Wildlife Refuge is located in Garden County near the heart of the Nebraska Sandhill Lakes Region. This country is principally rolling mid-grass prairie, the hills reaching a height of as much as 200 feet above the wet meadows. A good portion of the refuge's 46,000 acres consists of these lush meadows which are pocked by marshes, potholes and small lakes. Natural drainage from the surrounding sandhills and springs in the basins feed these water bodies.

The lakes are quite shallow, reaching a depth of perhaps 15 feet. They are alkaline yet are not so highly basic …

Studies On The Helminth Fauna Of Alaska. Xliv. Revision Of Ogmogaster Jägerskiöld, 1891, With A Description Of O. Pentalineatus Sp. N. (Trematoda: Notocotylidae), Robert L. Rausch, Francis H. Fay

Harold W. Manter Laboratory of Parasitology: Faculty Publications

Discrepant conclusions in the literature concerning the specific distinction of the two spe- cies assigned to the genus Ogmogaster Jägerskiöld, 1891, necessitated a reevaluation of the taxonomic characters used in separating these trematodes. Study of material from baleen whales from North Pacific waters and from baleen whales and lobodont pinnipeds from the southern hemisphere disclosed the existence of two species which can be distinguished by consistent differences in numbers of ventral ridges, ratio of length of cirrus sac to length of body, and by other morphological characters. Since the original description of O. plicatus (Creplin, 1829) does not permit certain …

The Emergence Of Correctional Law And The Awareness Of The Rights Of The Convicted, Eugene N. Barkin

Nebraska Law Review

The administration of criminal justice consists of four major areas: the arrest and charge of the commission of the offense; the trial and appeal; the disposition after a verdict of guilty; and finally the implementation of the judgment. Criminal law has traditionally been treated lightly by most law schools, practicing lawyers, and even the bench. And the most neglected area of this neglected field of law has related to the disposition of the offender's case; that is, sentencing and his rights thereafter. The purpose of this brief discussion is to promote awareness of the myriad of complex legal and human …
