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

A Preliminary Study Of The Hydrogeology Of The Dakota Formation In Douglas, Sarpy And Washington Counties, Eastern Nebraska, Thomas Mark O'Connor
A Preliminary Study Of The Hydrogeology Of The Dakota Formation In Douglas, Sarpy And Washington Counties, Eastern Nebraska, Thomas Mark O'Connor
School of Natural Resources: Dissertations, Theses, and Student Research
This study provides preliminary information on the hydrogeology of the Dakota Formation within a 1,000 square-mile area in eastern Nebraska. Isopach maps of the Dakota Formation and individual sand and gravel beds were constructed using a computer contouring program. Hydraulic conductivity values for water-bearing sand beds in the Dakota were estimated using the equation for calculating the specific capacity of wells and results from a grain-size analysis. Concentrations of major dissolved species were determined for samples collected from twenty five wells. The Dakota Formation is characterized by an increase in thickkness and an increase in percentage of clay versus sand …

Development Of Oriented Lakes In The Eastern Rainbasin Region Of South Central Nebraska, James P. Krueger
Development Of Oriented Lakes In The Eastern Rainbasin Region Of South Central Nebraska, James P. Krueger
School of Natural Resources: Dissertations, Theses, and Student Research
The Eastern Rainbasin region is located on a relatively flat-lying, loess-covered plain. The gently sloping land surface is poorly drained and in places local drainage is toward basins which lack external drainage. In the spring, excell precipitation collects in these basins, forming small lakes and marshes. It is these ephemeral lakes that give the region its name.
