Extreme Evapotranspiration By Irrigated Alfalfa: A Consequence Of The 1976 Midwestern Drought, Norman J. Rosenberg, Shashi Verma

School of Natural Resources: Faculty Publications

The rate of evapotranspiration by irrigated alfalfa at Mead, NE (41°09'N; 96°30'W, elevation 354 m) reached record levels in 1976. Evapotranspiration was measured with precision weighing lysimeters in a field 1.9 ha in size. Evapotranspiration ranged during the growing season from 4.75 to 14.22 mm day^–1 and exceeded 10 mm day­^–1 on one-third of the days studied. On each day of study the ratio of latent heat flux density (LE) to the sum of the net radiation and soil heat flux densities (Rn+S) was such that LE/ (Rn+S) > 1, indicating the occurrence of significant sensible heat advection.

Comprehensive Plan For Fish And Wildlife On Nebraska National Forest System Lands

Nebraska Game and Parks Commission: Publications

Wildlife and fish are integral and functional parts of forest and grassland environments. Application of this plan should improve and maintain habitats, as well as the types and populations of wildlife species within them. Various types of habitat manipulation are effective means of improving such environments to produce a diversified and sustained supply of wildlife. and fish. Direct habitat improvement and coordination with other resource management programs will be used to help realize the management objectives as they concern lands under Forest Service administration. However, this plan is not a "recipe book," requiring specified ingredients or actions. Rather it provides …

The Mcconaughy Rainbow...Life History And A Management Plan For The North Platte River Valley, Rodney C. Van Velson

Nebraska Game and Parks Commission: Publications

McConaughy Reservoir and the North Platte River drainage upstream to the Nebraska-Wyoming state line represent a major part of the coldwater habitat in Nebraska, 87%, according to the 1972 Nebraska Fish and Wildlife Plan (Figure 1). The plan also showed the upper North Platte River drainage contains 159 miles of coldwater stream habitat and 192 miles of mixed cold and warm water stream habitat, 29 percent of the total mileage in the state. Together, these 351 miles account for 80 percent of the coldwater stream acreage in Nebraska.

Wildlife Habitat In The James River Valley, South Dakota, L. Paul Schneider

Electronic Theses and Dissertations

A wildlife habitat inventory was conducted on the 12 485 ha study area of the James River floodplain in north-eastern South Dakota. Included were vegetation mapping, small mammal trapping, waterfowl breeding pair counts, waterfowl brood counts, bird census routes, and general observations. Natural vegetation consisted of 3181 ha of grassland, 2002 ha of woodland, 1115 ha of savannah, and 392 ha of marshland. Small mammal trapping revealed low densities of mostly white-footed mice (Peromyscus spp.). No vegetation type was more valuable to small mammals than any other. Waterfowl breeding pairs, mostly mallard, blue-winged teal, and wood duck, numbered 244 in …

Movement And Migration Patterns Of Red-Winged Blackbirds: A Continental Overview, Richard A. Dolbeer

United States Department of Agriculture Wildlife Services: Staff Publications

From 1924 through 1974, about 11,000 recoveries accumulated from the banding of over 700,000 Red-winged Blackbirds(Agelaius phoeniceus) in North America. A few studies have examined some of these data for specific localities during certain times of the year; however, no attempt has been made to examine the total recovery data to compile a general picture of continental movement and migration patterns. Increasing attention is being given to blackbird (Icteridae) and Starling (Sturnus vulgaris) populations in North America because of their reported crop depredations, health hazards, and nuisance aspects, especially when congregating in large roosts (Meanley,1975;Graham, 1976). Solutions to these problems …

Studies On The Role Of Solar Ultraviolet Radiation In "Natural" Water Purification By Aquatic Ecosystems, John Calkins, Jeanne A. Barcelo, Perry Grigsby, Stephen Martin

KWRRI Research Reports

The possibility that pollution might deplete the stratospheric ozone layer and intensify solar UV at the earth's surface focuses attention on the role of solar UV in the various ecosystems at the earth's surface. Previous studies suggested that solar UV might contribute to bacterial die off in wastewater and the studies reported here were directed toward elucidating the action of solar UV in "natural" waters.

It has been assumed that solar UV action on aquatic ecosystems can be evaluated (using proper models) on the basis of the following four independently measurable quantities: I) the intensity of solar UV at the …

Hydrology And Water Quality In The Central Kentucky Karst: Phase Ii Part A: Preliminary Summary Of The Hydrogeology Of The Mill Hole Sub-Basin Of The Turnhole Spring Groundwater Basin, James F. Quinlan, Donald R. Rowe

KWRRI Research Reports

Water from upland areas flows to small ephemeral and perennial springs that feed sinking streams that are tributary to low-order cave streams. These cave streams, also recharged by diffuse percolation, are part of a dendritic network in which intermediate-order streams join high-order streams that flow to major trunk streams. The trunk in the Mill Hole Sub-basin flows across the bottom of a large karst window, Mill Hole, and joins the trunk of the Patoka Creek Sub-basin. Their combined discharge bifurcates, flows around the collapsed central core of a larger karst window, Cedar Sink, and re-joins to flow as one to …

Final Report On Environmental Effect Of Subaqueous Sand Fill Acquisition On The Benthic Communities Of Hampton Bar, James River, Virginia, Robert J. Diaz, Donald F. Boesch

Reports

The Newport News Shipbuilding and Drydock Company was granted permission to obtain sand fill from the east end of Hampton Basin Hampton Roads, Virginia for the expansion of their waterfront facilities. A clamshell dredge operated from February to July 1974 and removed a total of 597,055 cu yds of material before breaking down. In August 1974 a hydraulic dredge took over the operation and by February 1975 had removed 899,386 cu yds for total removal of 1,495,410 cu yds.

In order to assess the environmental effects of this project a program of sampling benthic organisms was undertaken from February 1974 …

Evaluation Of Salinity And Temperature As Stress Factors Affecting The Enumeration Of Fecal Coliforms By The Electrochemical Detection Method, Howard I. Kator, Martha W. Rhodes

Reports

The ability of an electrochemical detection method to predict viable numbers of fecal coliforms was evaluated under laboratory conditions with respect to seawater adjusted to various salinities and temperatures. The viability of an Escherchia coli isolat~ as measured by the spread plate technique utilizing non-selective media was unaffected after 12 wk exposure at 2°C and 25 °100 salinity. At higher temperatures (15-30°C) both the total decrease in cell numbers as well as the rates of die-off were greater than at 2°C. There was little apparent difference in viability across the temperature range 15-30°C. Viability was observed to be inversely related …

Depuration Of Kepone By Atlantic Croaker In A Laboratory Study, Robert T. Doyle, J. V. Merriner, M. E. Bender

VIMS Books and Book Chapters

Contamination of the James River in Virginia by the organochlorine pesticide Kepone R prompted depuration studies of commercially important species. Approximately 400 croaker (Micropogonias undulatus) were taken from the James River and placed in Kepone-free York River water. Groups of 20 fish, maintained at ambient temperature, were sampled over time to determine depuration rate. Results suggest that there is no substantial depuration of Kepone by croaker until water temperature exceeds 15 C.

A Simulation Model For Ring-Necked Pheasants, Melvin W. Taylor

Nebraska Game and Parks Commission: Staff Research Publications

One of the most important game birds in the United States is the ring-necked pheasant (Phasianus colchicus). This Asian refugee has provided recreation for untold numbers of sportsmen. Its presence has meant millions of dollars for state game agency coffers, not to mention its impact on local economies. Pheasant populations have fluctuated widely in past years, but the overall trend since the early 1960's has been downward over most of the pheasant range. This decline was caused primarily by loss of habitat due to change in agricultural land use (Mohlis 1974, Dahlgren 1963, Kobriger 1972, Taylor et al. …

Interagency Conflict And Its Effect On Intermodal Shipping, Gerald Seifert

Marine Affairs Theses and Major Papers

The movement of goods by more than one mode of transportation in a single container has been viewed by some in the marine component of the transportation industry as a transformation a important as the coming of steam. Concerns with intermodalism and the difficulties faced in addressing the needs presented by the technologically enhanced maritime transportation industry do not start with the invention of the first multi-package container capable of being moved by several modes of transportation without need to repack; they start with an exploration of the perceived need to regulate the several components of the transportation industry, the …

A Proposal For A World Ocean Management Authority: As An Alternative Ocean Regime To Meet The Challenge Of The Management And Utilization Of Collective Ocean Activities, Simon W. Tache

Marine Affairs Theses and Major Papers

The oceans may be an alternative source of resource supply offering the opportunity for extensive practical uses. A number of ocean systems have been instituted to manage the exploitation of ocean resources including the practice of states to negotiate and enter into bilateral and multilateral agreements on a variety of ocean activities; but the complexities as well as the tendency of some of these ocean uses to generate extraterritorial effects, accentuate the need for a global response to alleviate these problems. Isolated individual national regulations and standards lack international uniformity to ensure adequate and rational utilization of the oceans and …

A National Approach For Marine Scientific Research In Exclusive Economic Zones, Thomas H. Brillat

Marine Affairs Theses and Major Papers

After years of constant negotiations at the Third United Nations Conference of the Law of the Sea (UNCLOS III), no new codified law for the seas has been produced. It appears certain, though, that countries throughout the world will exercise some form of sovereignty or national jurisdiction over an Exclusive Economic Zone (EEZ) extending 188 miles into the ocean beyond a twelve mile territorial sea. Included in this jurisdiction will be the control of marine scientific research (MSR). A need has arisen to establish a uniform procedure for the conduct of MSR to the mutual advantages of the coastal state, …

Soil Salinity In Western Australia : A Summary, T C. Stoneman

Journal of the Department of Agriculture, Western Australia, Series 4

Soil salinity problems have long been recognised in Western Australia. The earliest published explanation in 1924 suggested that removing native vegetation increased stream salinity, and this basic cause has been confirmed by many studies since.

Final Report Buffalo National River Ecosystems Part Iv, R. E. Babcock, E. E. Dale, R. L. Meyer, D. G. Parker, E. G. Smith, M. D. Springer

Technical Reports

Sampling point locations and analytical procedures remained unchanged from those outlined in previous Buffalo National River Ecosystem reports. The only significant change in analytical procedures was a reversion to the glass fiber filter method for collection and extraction of samples for chlorophyll analysis. This change was neeessitated by a need for filtering a larger volume to obtain enough chlorophyll for an accurate measurement. Samples were collected monthly from April 9 through December 30. No samples were taken in January or February due to the extremely uncertain traveling conditions caused by the frequent snows. Prior research indicates that the December 30 …

Bird Utilization Of Woodland Habitat In The Eastern Quarter Of South Dakota, John M. Emmerich

Electronic Theses and Dissertations

Bird utilization of narrow, riparian woodland; riparian; block-like, tree claim; and linear, single-row windbreak habitats in the eastern quarter of South Dakota were studied during the spring migration, reproductive, and winter seasons. The relative importance of these three habitats and multi-row shelterbelt habitat was evaluated using bird species diversity (BSD), bird population density, and habitat preferences of individual bird species. Cluster analysis delineated distinctive vegetation cover types in each of the three habitats studied. Bird communities associated with each cover type were tabulated for comparison purposes and predication capabilities. Multiple regression analysis predicted physical and vegetation features of each habitat …

Diversity And Density Of Shelterbelt Bird Communities, Thomas E. Martin

Electronic Theses and Dissertations

The number of bird species and the density of each species were monitored in 69 shelterbelts in eastern South Dakota during spring migration and breeding seasons in 1976 and 1977. A total of 44 different species of birds were found during breeding and 68 species during spring migration. Approximately 60 to 80% of the species in a shelterbelt eat insects as part of all of their diet. Most of these bird species are territorial. Usually only 1-2 pairs of a territorial species will reside in any one shelterbelt. This low density is caused by the limited habitat area that shelterbelts …
