The Influence Of Redd Distribution And Microhabitat Availability On The Distribution And Abundance Of Young-Of-The-Year Trout In The Green River, Utah, Michael J. Buntjer
The Influence Of Redd Distribution And Microhabitat Availability On The Distribution And Abundance Of Young-Of-The-Year Trout In The Green River, Utah, Michael J. Buntjer
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
Redd distribution, redd density, and physical habitat were used to explain the distribution and abundance of young-of-the-year (YOY) brown trout (Salmo trutta) and rainbow trout (Oncorhynchus mykiss) in the Green River, Utah. The importance of variables at both a microhabitat and macrohabitat scale were assessed using stepwise regression analysis. Availability of cover (rock and vegetation) and proximity to spawning sites were the most important variables used to explain the distribution and abundance of YOY brown trout and rainbow trout. In addition, YOY brown trout and rainbow trout occupied specific microhabitats and showed patterns of use for …
An Updated Phylogenetic Classification Of The Flowering Plants, Robert F. Thorne
An Updated Phylogenetic Classification Of The Flowering Plants, Robert F. Thorne
Aliso: A Journal of Systematic and Floristic Botany
This update of my classification of the flowering plants, or Angiospermae, is based upon about 800 pertinent books, monographs, and other botanical papers published since my last synopsis appeared in the Nordic Journal of Science in 1983. Also I have narrowed my family- and ordinal-gap concepts to bring acceptance of family and ordinal limits more in line with those of current taxonomists. This new information and the shift in my phylogenetic philosophy have caused significant changes in my interpretation of relationships and numbers and content of taxa. Also the ending "-anae" has been accepted for superorders in place in the …
G92-1097 Root And Crown Rot: Winterkill Complex Of Winter Wheat, John E. Watkins, Ben Doupnik, Jr., Eric D. Kerr, Robert N. Klein
G92-1097 Root And Crown Rot: Winterkill Complex Of Winter Wheat, John E. Watkins, Ben Doupnik, Jr., Eric D. Kerr, Robert N. Klein
University of Nebraska-Lincoln Extension: Historical Materials
Root and crown rot--winterkill complex is discussed, including nature of the complex, symptoms, control, and management rationale. Root and crown rot of winter wheat is an interrelated disease complex caused by the interaction of infection of roots and crowns by Bipolaris sorokiniana and/or Fusarium graminearum and harsh winter conditions. It is an insidious, persistent and inconspicuous disease complex that reduces wheat yields each year. In extreme cases, entire fields or large areas within fields are killed. The ultimate effect is loss of stands, poor plant vigor, reduced yield and lower grain quality.
