The Lemming Vole, Synaptomys Borealis, In Northern Minnesota, Ralph M. Wetzel, Harvey L. Gunderson

University of Nebraska State Museum: Mammalogy Papers

Lemming voles of the subgenus Mictomys have never been recorded from north-central United States, although they might be expected to occur there judging from records of the species Synaptomys (Mictomys) borealis from southern Manitoba. Recently, examination of specimens in the collection of the Minnesota Museum of Natural History reveals that Synaptomys borealis does occur in north-central United States for we have found the following specimens referable to that species: one immature female (No. 951, MMNH) from Williams, Lake of the Woods County, Minnesota, collected by Gustav Swanson, August 5, 1932; one adult male (No. 2552, MMNH) from Warroad, Roseau County, …

Management Of Native Deer In Nebraska, John H. Wampole, Edson Fichter

Nebraska Game and Parks Commission: Publications

Deer are on the increase in Nebraska. Reports of deer seen, of deer killed on highways, and of localized cases of damage to crops by deer have become increasingly frequent during the last ten years. Since Nebraska is not primarily a land of forests nor of great repute as a deer state, the presence of these mammals in more than rare occurrences arouses considerable interest-and creates new problems in wildlife management.

It is the purpose of these notes to answer some of the questions most commonly asked about deer in Nebraska, and to point out certain misunderstandings which have led …

Effects Of Weather, Sanitation And Chlorinated Chemical Residues On House And Stable Fly Populations On Nebraska Farms, Martin H. Muma, Ephriam Hixson

Department of Entomology: Faculty Publications

Since L. O. Howard's (1906) early report on house flies many entomologists have conducted research on these insects. Their reports range from notes on the hibernation of house flies, Musca domestica L., to lengthy papers on the biology and control of house flies and stable flies, Stomoxys calcitrans (L.). Early control studies stressed the importance of sanitatioll, screening and the use of mist type contact insecticides. These standard control measures have not, however, received much attention in the United States since Wiesmann (1943) reported on the pro-longed effectiveness of a new insecticide "Gesarol." Scores of other workers have also published …

Studies In Quantitative Paleontology Ii. Multivariate Analysis—A New Analytical Tool For Paleontology And Geology, Benjamin H. Burma

Department of Earth and Atmospheric Sciences: Faculty Publications

Multivariate analysis is the simultaneous comparison of three or more variables in order to determine the significance of their likenesses and differences. The technique has been in use for some thirteen years, but no simple account of the method has hitherto been available. An illustrative example from invertebrate paleontology is here used, but the method is applicable to any problem in geology involving several quantitatively known variables.

Mechanical Transmission Of A Plant Tumor Virus To An Insect Vector, Karl Maramorosch, Myron K. Brakke, L. M. Black

Department of Plant Pathology: Faculty Publications

Most plant viruses transmitted by leafhoppers have not been demonstrated to be infective in extracts. The virus dealt with in this paper causes tumors in certain susceptible plants, is carried by leafhoppers, and like others in that group has proven difficult to detect in extracts. It is our purpose to recount briefly the variety of methods that failed to transmit the virus and to report on the success of insect-to-insect transmission by injection.

Evidence For A Tryptophane Cycle In Neurospora, Francis A. Haskins, Herschel Mitchell

Department of Agronomy and Horticulture: Faculty Publications

The work of Snell on lactic acid bacteria provided the first evidence that anthranilic acid may act as a precursor to tryptophane in vivo. Since the strains of bacteria which utilize anthranilic acid in the place of tryptophane also use indole, it was not possible to establish the order in which these two precursors occurred. In 1943 Tatum, Bonner and Beadle found that anthranilic acid was accumulated in the culture medium by a Neurospora crassa mutant, strain 10575, which required either tryptophane or indole for growth. It was therefore indicated that anthranilic acid is a precursor to indole in …

A Metabolic Relationship Between The Aromatic Amino Acids, Joseph F. Nyc, Francis A. Haskins, Herschel K. Mitchell

Department of Agronomy and Horticulture: Faculty Publications

The present work involves a further investigation of a Neurospora mutant, C-86, previously mentioned by Lein, Mitchell and Houlahan (1) as one that can utilize anthranilic acid, indole, tryptophan, kynurenine, 3-hydroxyanthranilic acid, and nicotinic acid as supplements for growth. Mutant C-86, when crossed to a “wild-type” strain, was found to differ from this wild type strain, with respect to tryptophan biosynthesis, by a mutation at a single locus. The evidence presented suggests the possibility of a common precursor to the aromatic amino acids.

The Occurrence Of Platynosomum Illiciens (Braun, 1901) In A North American Hawk., J. Fred Denton, Robert Rausch

Harold W. Manter Laboratory of Parasitology: Faculty Publications

A series of 160 hawks of 12 species from ten states and the Province of Manitoba has been examined for dicrocoeliid trematodes. Only one species of dicrocoeliids was found in them indicating the infrequency with which North American hawks are infected with trematodes of this group.

Of the 160 hawks examined 4 were broad-winged hawks. Buteo platypterus, 2 of which, collected in Ohio and Wisconsin, harbored in their bile ducts 3 and 8 specimens respectively of a trematode of the genus Platynosomum. These specimens, after comparison with both the original and the recently expanded description by Travassos (1944, …

Some Observations On Cestodes Of The Genus Paranoplocephala Luehe, Parasitic In North American Voles (Microtus Spp.), Robert Rausch, Everett L. Schiller

Harold W. Manter Laboratory of Parasitology: Faculty Publications

Although cestodes of the genus Paranoplocephala Luehe, 1910, are common parasites of voles and certain other rodents in North America, their taxonomic status to the present time has been much confused. It is the purpose of this paper to clarify the situation in regard to those species parasitic in voles of the genus Microtus Schrank.

While certain of the cestodes considered here occur in hosts of other microtine genera, they are by far more abundant in the various species of Mi· crotus. At least two are also common in geomyid rodents. With the possible exception of Paranoplocephala brevis Kirschenblatt, …

Use Of Motion Pictures In Laboratory Dynamical Studies, Carl Bailey, Jaan Jurisson, M. Eugene Rudd

M. Eugene Rudd Publications

In student laboratory experiments in dynamics, as, for example, Newton's second law of motion or the conservation of momentum, it is, of course, highly desirable to allow motion with the least possible constraint and to observe the displacements of moving parts without using perturbing markers. This circumstance has led us to use motion pictures in the student laboratory for quantitative observation of rapid dynamic processes, a technique which is used in a well-known textbook.' The photographic method combines maximum freedom of movement with accurate observation of position as a function of time, if the camera frame speed is sufficiently high. …

Studies On The Parasitic Helminths Of The North Central States. Ii. Helminths Of Voles (Microtus Spp.) Preliminary Report, Robert L. Rausch, Jack Tiner

Harold W. Manter Laboratory of Parasitology: Faculty Publications

The helminths of North American mouse-like rodents have received little study. Previous work has been based on low numbers of animals examined, and there has been little reference to the ecology involved. The purpose of this paper is to present data resulting from the examination of over 600 voles, with special reference to host-parasite relationships
