Three-Dimensional Ultrastructure Determination Of Wheat Streak Mosaic Virus Pin Wheel Inclusion Bodies Through The Use Of Analytic Geometry, And High Resolution Electron Microscopy And Signal Analysis And Dissemination Equipment Studies Of Ultrastructure, Raymond Leroy Mernaugh Jan 1976

Three-Dimensional Ultrastructure Determination Of Wheat Streak Mosaic Virus Pin Wheel Inclusion Bodies Through The Use Of Analytic Geometry, And High Resolution Electron Microscopy And Signal Analysis And Dissemination Equipment Studies Of Ultrastructure, Raymond Leroy Mernaugh

Electronic Theses and Dissertations

This study was undertaken for several reasons. The primary reason for the study was to determine the three-dimensional shape of the viral pin wheel inclusion in order to confirm or deny the three-dimensional structures put forth by Edwardson (15), Andrews and Shalla (1); or to establish another different pin wheel inclusion three-dimensional shape yet undescribed in previous literature. A secondary reason for the study lies in the fact that if this technique described in this paper was deemed acceptable, it could be employed to determine quickly, from two-dimensional electron micrographs, the three-dimensional ultrastructural shapes of many features seen in electron …

Investigation On Several Aspects Of The Epidemiology And Control Of Wheat Scab, Dale E. Miller Jan 1976

Investigation On Several Aspects Of The Epidemiology And Control Of Wheat Scab, Dale E. Miller

Electronic Theses and Dissertations

The distribution of wheat scap is worldwide; in the U.S. the disease is the most prevalent in the central and eastern regions. The fungus attacks both spring and winter wheat, as well as many other Gramineous plants, including barley, oats, rice and some wild grasses. Among dicotyledon plants, the fungus causes root and crown disease of pea and carnation. With more wheat acreage each year, a build-up of the pathogen population is likely, and therefore pose a greater problem in the future. Today’s use of cultural practices that leave large amounts of surface residue in the fields may provide the …

Use Of Stockpods For Nesting By Giant Canada Geese, Paul M. Bultsma Jan 1976

Use Of Stockpods For Nesting By Giant Canada Geese, Paul M. Bultsma

Electronic Theses and Dissertations

A study of giant Canada geese (Branta canadensis maxima) nesting on stockponds in western South Dakota was conducted during 1974 and 1975. Analysis of 10 selected variables at nests on natural sites indicated that distance of water below high water level and percent slope from wetland to horizon, contributed the most to the use of the site. Distance from wetland to horizon and disturbance factors were two important variables measured to determine use of artificial nesting structures. First nests were initiated on 1 April 1974 and 8 April 1975. Twenty-five nests (16 percent) were located on artificial nesting structures, and …

The Aquatic Ecology Of Two Seasonal Marshes In Eastern South Dakota, Walter K. Donaldson Jan 1976

The Aquatic Ecology Of Two Seasonal Marshes In Eastern South Dakota, Walter K. Donaldson

Electronic Theses and Dissertations

Zooplankton, benthos, nekton, aufwuchs, and the physical-chemical limnology of two seasonal marshes in eastern South Dakota were monitored from April-June 1975. Bothwell and Lund Marshes contained water from 15 April-July 1975. The dominant i. ons, Ca ++, Mg+ +, and sulfate, made the water hardness non-carbonate. Floating vegetation, Lemna trisulca and Cladophora sp., became abundant in both marshes during the first week of June, and formed large thick mats by the end of June 1975. Daphnia pulex was the dominant zooplankter in Bothwell Marsh and made up 33% of the zooplankton density during the 1975 season. The population was triacmic, …

Effects Of P.L. 566 Stream Channelization On Wetlands In The Prairie Pothole Region, Ronald E. Erickson Jan 1976

Effects Of P.L. 566 Stream Channelization On Wetlands In The Prairie Pothole Region, Ronald E. Erickson

Electronic Theses and Dissertations

The Wild Rice Creek Watershed project, in North and South Dakota was constructed under authority of the Small Watershed Protection and Flood Prevention Act (P.L. 83-566 as amended). Structural measures included 24.7 miles of channelization and four floodwater retarding dams. To measure the degree that channelization influenced drainage of prairie wetlands, drainage rates in a channelized tributary were compared to rates in an unchannelized tributary of Wild Rice Creek. Channelization had a direct impact on wetlands by channel drainage reduction of overbank flows, and by providing drainage outlets. Indirect (secondary) wetland losses are believed to have occurred outside of the …
