Wing Loading In Plecotus Rafinesquii, Clyde Jones, Royal D. Suttkus

United States Fish and Wildlife Service: Publications

Considerable interest has developed in recent years with regard to studies of wing areas and wing loadings of North American bats (Davis and Cockrum, 19645; Jones, 1967; Davis, 1969; Farney and Fleharty, 1969). To our knowledge, such data have not been presented for Plecotus rafinesquii, one of the least known of North American species (Barbour and Davis, 1969). The purpose of this report is to provide information on flight of P. rafinesquii species, as well as adults of two other species of Plecotus.

Seventy-one P. rafinesquii were studied: five were banded and released and 66 were preserved either as skins …

The Occurrence And Significance Of Polychlorinated Biphenyls In The Environment, E.H. Dustman, L.F. Stickel, L.J. Blus, W.L. Reichel, S.N. Wiemeyer

United States Fish and Wildlife Service: Publications

The natural world today contains a vast array of man-made chemicals, many of them with biological potency in quantities scarcely measurable tow decades ago. Wild animals encounter these chemicals in multifold combination, but man's knowledge of their effects on wild species progresses haltingly. While research focused on DDT, dieldrin, and related chemicals that were obvious suspects for cause of environmental problems, other compounds, some unidentified, spread and increased.

Polychlorinated biphenyls (PCB's) constitute one such group. PCB's are products of modern industrial chemistry that have escaped to the environment by routes still largely unknown. They have become ubiquitous in the world …

The Flathead Catfish In Unchannelized And Channelized Missouri River, Nebraska, Larry A. Morris, Ralph Langemeier, Arthur Witt Jr.

Nebraska Game and Parks Commission: White Papers, Conference Presentations, and Manuscripts

Flathead catfish, Pylodictus olivaris (Rafinesque), were studied in approximately 83.7 km of unchannelized and 67.6 km miles of channelized Missouri River. Growth rates were slower in the unchannelized section than they were in the channelized section. The oldest fish in the unchannelized section was 25 years old, while in the channelized study area the oldest was 10 years. In the pectoral spines of progressively older fish from both sections, enlargement of the lumen obliterated early annuli. Much of the annual increment of growth was accomplished during June, July and August. Males became sexually mature at 3 to 4 years of …

An Ecological Rationale For The Natural Or Artificial Regulation Of Native Ungulates In Parks, Glen F. Cole

United States National Park Service: Publications

The results from studies of both naturally and artificially regulated ungulate populations in four Rocky Mountain parks are reviewed. Study findings on population regulation processes, the role of predators, natural mortality and natality, and ungulate habitat and food relationships suggest that previous assumptions which were the basis for artificially regulating ungulates over-estimated the regulatory effects of predators and did not always distinguish natural from human-influenced conditions or changes. The suggested rationale for artificially regulating native ungulates in Rocky Mountain parks is: a human influence that causes unnatural successional trends by restricting ungulates from freeranging over an ecologically complete habitat (1) …

The Biological Activity Of Phytotoxic Extracts From Corynebacterium Sepedonicum, Doran W. Pearson

Open Access Master's Theses (through 2010)

Isolation of a phytotoxin from the ring rot pathogen of potatoes, Corynebacterium sepedonicum, had previously been reported by Strobel (21). The first phase in our study was to investigate more extensively the general nature of this compound. The phytotoxin could possibly be a specific compound associated only with the ring rot pathogen. However, the possibility that the substance could be obtained from sources other than the bacterium had not been completely eliminated. In an attempt to answer this question, three extracts were purified and compared. First, compounds were isolated from a broth culture of bacteria in the manner described …

Hatching Of Sod Webworm Eggs In Relation To Low And High Temperatures, Ellis L. Matheny, E. A. Heinrichs

Department of Entomology: Faculty Publications

Eggs of 12 species of sod webworm were exposed for various periods to temperatures of 0, 10, and 45°C. Hatchability was compared with control eggs kept at 25°C. Short exposures to any temperature did not significantly affect percent hatch. Prolonged exposure resulted in a significant decrease in hatchability for several species at 0° and for all species at 45°C. There was a significant difference in hatchability between the 3 generations of Crambus teterrellus (Zincken) and of Pediasia trisecta (Walker) at extreme temperatures. Populations of Agriphila ruricolella (Zeller), collected at 2 elevations, differed significantly in hatching percentage and developmental rate.

Observations On Parasite-Host Relationships Of Echinococcus Multilocularis Leuckart, 1863, In North Dakota, Robert L. Rausch, S. H. Richards

Harold W. Manter Laboratory of Parasitology: Faculty Publications

Red foxes, Vulpes vulpes (Linnaeus), and small mammals were collected and examined during 1965-1969, to investigate parasite-host relationships of Echinococcus multilocularis Leuckart, 1863, in North Dakota. Comparative studies of this cestode were carried on concurrently through experimental infection of carnivores and rodents. In winter, red foxes in North Dakota exhibited high rates of infection of comparatively low intensity. Deer mice, Peromyscus maniculatus (Wagner), and voles, Microtus pennsylvanicus (Ord), were important intermediate hosts, but the larvae in deer mice produced fewer protoscolices. The strains of E. multilocularis from North Dakota and from St. Lawrence Island, Alaska, differ biologically, as indicated by …

The Fishes Of The Nemaha Basin, Nebraska, Larry Witt

Nebraska Game and Parks Commission: Staff Research Publications

The possible effects of proposed watershed management practices on fish resources of the Nemaha Basin were poorly understood; thus, a study was undertaken to ascertain the species of fish present and their relative abundance and distribution within the basin. Thirty-five species were collected, 34 of them from the Big Nemaha River system and 28 from the Little Nemaha River system. These data may be used as a basis for future studies of fish population changes in the Nemaha Basin and possibly as a basis for studies in other watersheds.

Orderly Production And Marketing In The Beef-Pork Sector, John E. Trierweiler, James B. Hassler

Nebraska Agricultural Experiment Station: Historical Research Bulletins

This study will present economic models for analyzing temporal equilibrium positions for the beef-pork sector. The issues of spatial distribution, storage, and meat forms will not be directly analyzed. Grade and yield changes for various carcass classes will, however, be implied in the carrying costs of the animal. The models will be designed such that a number of different factors that affect the production and marketing of beef and pork can be analyzed simultaneously.

Bioassay Procedures For Oil And Oil Dispersant Toxicity Evaluation, Gilles Laroche, Ronald Eisler, Clarence M. Tarzwell

United States Environmental Protection Agency: Publications

Hazards to marine and estuarine fauna associated with offshore drilling of oil and with transport of large quantities of oils via tankers are numerous and understandable. At present, there is a growing body of evidence on adverse effects to these organisms of crude oil (1) (2) (3) (4) (5) (6) (7) (8) (9) and chemical oil counteracting agents or dispersants (5) (6) (9) (10) (11) (12) (13) (14) (15) (16) (17). These effects are well summarized by Smith (18) and by Carthy and Arthur (19).

Comparatively few workers have studied the influence of oil-dispersant mixtures of marine life. Studies by …

Harold W. Manter Laboratory of Parasitology: Faculty Publications

Cestodes representing six species of the genus Diphyllobothrium Cobbold, 1858, were collected from naturally infected terrestrial mammals in Alaska during the period 1949-1970. Additional specimens were reared in experimentally infected animals. Of the species identified, viz., D. latum (Linnaeus, 1758), D. dendriticum (Nitzsch, 1824), D. lanceolatum (Krabbe, 1865), D. ursi Rausch, 1954, D. dalliae Rausch, 1956, and D. alascense Rausch and Williamson, 1958, all but D. alascense were obtained from man after treatment with quinacrine. D. latum occurred most commonly in humans; D. ursi is reported for the first time from this host, and D. lanceolatum in humans was represented …

Collecting Slime Flux Feeding Coleoptera In Japan, Brett C. Ratcliffe

University of Nebraska State Museum: Entomology Papers

Sappy wounds of injured or diseased trees entice a wide variety of insects. Carter (1945) stated that when fluxing is prolific or long continued, air-borne bacteria, yeasts, and fungi contaminate the oozing sap, ferment it and produce the material called slime flux. Apparently the oozing flux is toxic to the flux site and so prevents callusing by the tree. Consequently, the same tree usually can be a good collecting site for insects from year to year. My stay in Japan spanned four years, and collecting at flux sites was one of the most fruitful areas of endeavor. As soon as …

Increase In Size Of Eimeria Separata Oocysts During Patency, Donald W. Duszynski

Harold W. Manter Laboratory of Parasitology: Faculty Publications

Examinations of 18 consecutive fecal samples collected at 6-hr intervals from infected rats showed that oocysts increased in length and width by approximately 40% from the beginning to the end of the patent period. Unsporulated oocysts were first observed in the 3rd fecal collection, 84 to 90 hr post-inoculation (PI) and 100 of these measured 9.9 to 14.3 by 8.8 to 12.1 μ (mean 11.7 by 10.1). Patency ended with the 15th fecal collection, 156 to 162 hr PI, and 100 unsporulated oocysts from this sample measured 14.3 to 17.6 by 13.2 to 15.4 μ (mean 16.3 by 14.2). Despite …

Territorial Male Red-Winged Blackbird Distribution In Wood County, Ohio, M. I. Dyer

Bird Control Seminars Proceedings

Red-winged blackbirds (Agelaius phoneiceus) have been studied intensively in the United States and Canada by research biologists of the Bureau of Sport Fisheries and Wildlife for more than a decade. The detailed information on popula¬tion dynamics of the species that has been acquired is now being assembled and assessed. Definite patterns in the distribution of some of the eastern and mid-western populations have become apparent (Dyer et al., 1072; Power, 1069, 1970). A very complex distribution of territorial densities occurs in the western Lake Erie Basin of the U.S. and Canada (Dyer et al., 1972), where there are significant differences …
