Habitat Use And Diet Analysis Of Breeding Common Barn-Owls In Western Nebraska, Joseph A. Gubanyi M.S.

School of Natural Resources: Dissertations, Theses, and Student Research

I studied barn owl (Tyto alba) breeding biology in western Nebraska 1984-1986. I had greatest success capturing males (56% success) at night using trap doors at nest sites and females (91 % success) using hoop nets at nest sites during the day. Barn owls removed 16 of 23 tail-mounted radios. Eight birds were radio-tracked for 7-14.5 hours. The mean foraging range was 198 ha (32- 299 ha, n = 8) with < 1 % overlap among birds from adjacent nest sites. Field-tested telemetry error was high (mean displacements of radio-locations for 2 birds were 208 and 241 m). I found no relationship between percent cover in foraging habitat and reproductive success. I identified 10,140 prey items from 15 nest sites and found both annual and seasonal variation in barn owl diets. Microtus ochrogaster occurred most frequently (32.7%) and increased in the diet from 17.6 to 27.2 to 43.5% 1984-1986. M. ochrogaster and Perognathus hispidus annual frequencies were …

Ozonation For Non-Filamentous Bulking Control In An Activated Sludge Plant Fuel Synthesis Waste Transfer, Johannes Van Leeuwen

Johannes van Leeuwen

A zero discharge mode of operation at the South African fuel synthesis plants necessitates the infinite recycle of treated industrial waste water. The treatment process incorporates activated sludge units in which non-filamentous bulking and carry-over of solids often occurs. The use of ozone for the control of this non-filamentous binding was investigated on a 33 l/d small pilot-scale plant. An ozone dosage of 1 g per kg mixed liquor suspended solids per day could reduce the diluted sludge volume index from an average of 125 to about 70 ml/g mainly by preventing zoogleal growths, the main contributor to the non-filamentous …

A Porpoise, Australophocaena Dioptrica, Previously Identified As Phocoena Spinipinnis, From Heard Island, Robert L. Brownell Jr., John Heyning, William Perrin

United States Department of Commerce: Staff Publications

Guiler, Burton and Gales (1987) reported a cranium (Tasmanian Museum No. A141 1) they identified as belonging to Burmeister’s porpoise, Phocoena spinipinnis Burmeister, 1865 from Heard Island (53°S 73°30’E). They noted that P. spinipinnis was previously known only from the cold-temperate coastal waters of South America and claimed that this cranium was evidence that the species has a much wider distribution than previously known. We have examined the photographs and details of their specimen and re-identify it here as Australophocaena dioptrica (Lahille, 1912) (family Phocoenidae).

Barnes (1985) listed several features that distinguish the skulls of species within the subfamily Phocoenoidinae …

Relocation Of City Raccoons, Richard C. Rosatte, Charles D. Macinnes

Great Plains Wildlife Damage Control Workshop Proceedings

Twenty-four city raccoons were radio-collared and relocated 25-45 km north of the original capture site in Toronto, Ontario. Following release, extensive exploratory movements were noted with distances of 2-7 km being traversed per night. Home ranges for adult males (avg = 39 km²) and females ( avg = 72 km²) far exceeded juvenile ranges and areas utilized by raccoons in an urban setting. None of the raccoons returned to the original point of capture and mortality of the relocated raccoons approached 50% during the first 3 months following release

Plio-Pleistocene Glacial Deposits In Northeastern Nebraska: New Exposures And Interpretations, M. R. Voorhies, R. G. Goodwin

School of Natural Resources: Faculty Publications

A field trip sponsored by the Nebraska Geological Society. Trip Leaders: Dr. M.R. Voorhies, University of Nebraska State Museum. & Dr. R.G. Goodwin, HWS Technologies Inc. Spring 1989

Recent interpretation of oxygen isotopic data for benthic and planktonic foraminifera recovered during ocean drilling programs suggest that world ice volume was greater than the ice volume of 18 thousand years ago (Late Wisconsinan) approximately 2.5 million years ago (Prentice and Matthews, Geology, November, 1988). This agrees well With biostratigraphic and paleoecologic interepretations drawn from sediment cores obtained from the Arctic Ocean Basin. The latter data suggest complete ice cover of the …

Use Of Respiratory-Cardiovascular Responses Of Rainbow Trout (Salmo Gairdneri) In Identifying Acute Toxicity Syndromes In Fish: Part 3. Polar Narcotics, Steven P. Bradbury, Tala R. Henry, Gerald J. Niemi, Richard W. Carlson, Virginia M. Snarski

Steven P. Bradbury

The physiological responses of rainbow trout to acutely lethal aqueous concentrations of the suspected polar narcotics phenol, 2,4-dimethylphenol, aniline, 2-chloroaniline and 4-chloroaniline were examined. Visible signs of intoxication included tremors that progressed to whole-organism clonic seizures, followed by general depression and respiratory-cardiovascular collapse. Tremors and seizures were usually initiated with coughs. The most striking changes in the respiratory-cardiovascular parameters for all five toxicants included elevated cough frequency (coincident with seizures), ventilation frequency and hematocrit, and depressed gill oxygen uptake efficiency, arterial pH, total arterial oxygen and total arterial carbon dioxide. The physiological responses noted were attributed to the initial muscular …

Red Swamp Crayfish Ecology In Lake Mead, Suzanne E. Leavitt, Jennifer Stephens Haley, Mikell Hager, Donald H. Baepler, Nevada Department Of Wildlife

Publications (WR)

Red swamp crayfish (Procambarus clarkii) were trapped in Flamingo Wash, an urban wash of Las Vegas, during four periods of 1988. Life history and reproductive success were determined. The trapped crayfish were marked and released into a study cove in Lake Mead as part of an experimental stocking program. Retrap data from the study cove were used to determine life history, habitat preferences, and movement patterns of the stocked crayfish. In addition, a literature search was done on red swamp crayfish ecology, including food preferences, life history, habitat preferences and fish predation.

The Use Of Dma To Reduce Robin Depredation On Cherries, Leonard R. Askham, John K. Fellman

Great Plains Wildlife Damage Control Workshop Proceedings

The use of a biorational pesticide, Dimethyl Anthrantlate (DMA), was investigated for possible use as a robin repellant in an Eastern Washington Research orchard. Applied in low concentrations (2, 4, and 8% with surfactant), robin depredation was reduced an average of 75%. A double-blind taste test showed no consumer aversion for fresh fruit sprayed with DMA two weeks before harvest.

Seasonal Variation In Habitat Use By Great-Tailed Grackles In The Lower Rio Grande Valley, John H. Rappole, Arlo H. Kane, Rafael H. Flores, Alan R. Tipton, Nancy Koerth

Great Plains Wildlife Damage Control Workshop Proceedings

Habitat use by great-tailed grackles was measured by performing weekly censuses of birds in 6 different habitat types: chaparral, citrus groves, feed lots, pastures, residential areas, and agricultural fields. We found that use of chaparral, citrus, and residential sites was low during the winter months, increased sharply with commencement of the nesting season in April, and declined again by October. Use of agricultural fields and pasture was irregular. Feed lot use was low during the summer, but high from October - April with October and March migration peaks. An overall sex ratio of 1.3 females/male was observed with skews from …

Experimental Applications Of High-Tensile Wire And Other Fencing To Control Big Game Damage In Northwest Colorado, A. Eugene Byrne

Great Plains Wildlife Damage Control Workshop Proceedings

Conventional fencing methods V-mesh wire, square mesh wire and wood panels are compared to experimental methods - 15 wire hightensile wire fences; electric high-tensile wire fences of three designs; baited electric fences; hog panel fences; plastic mesh fences and visqueen wrapped haystacks. Total cost of materials, cost per ft./yr. and comments concerning estimates of efficacy are discussed. The V-mesh wire, hog panel and plastic mesh fences all have a very high cost per ft. and cost per ft./yr. rating and should probably not be used. High-tensile and square mesh wire fences are effective and cheaper alternatives. Modern high-tensile wire electric …
