The Impact Of Surface Soil Removal On Plant Production, Transpiration Ratios, Nitrogen Mineralization Rates, Infiltration Rates, Potential Sediment Losses, And Chemical Water Quality Within The Chained And Reseeded Pinyon-Juniper Types In Utah, Steven M. Lyons
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
During the period of October 1974 to August 1976, a study was conducted to measure the effects of surface soil removal on plant production, plant transpiration rates, nitrate nitrogen mineralization rates, and selected hydrologic parameters (infiltration rates, potential sediment production, and chemical quality of runoff water). The treatments were incremental 7.6 centimeter soil layers to a depth of 30.5 centimeters.
Plant production and transpiration ratios (or water use efficiencies) were measured in greenhouse studies using Agrogyron desertorum grown in the incremental 7.6 centimeter soil layers from five study sites throughout the state of Utah, (Blanding, Brush Creek, Milford, Huntington, and …
Toxicity, Selectivity, And Efficacy Of Squoxin (1,1'-Methylendi-2-Napthol) To Fishes In Utah Waters, Dexter R. Pitman
Toxicity, Selectivity, And Efficacy Of Squoxin (1,1'-Methylendi-2-Napthol) To Fishes In Utah Waters, Dexter R. Pitman
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
Squoxin (1,1'-Methylendi-2-napthol) was tested in laboratory and field bioassays to evaluate its biological activity to rainbow trout (Salmo gairdneri), cutthroat trout (Salmo clarki), Utah chub (Gila atraria), carp (Cyprinus carpio), reside shiner (Richardsonius balteatus), and mountain sucker (Catostomus platyrhynchus) under various conditions of water quality and temperature. The compound was toxic to all species and most effective from greatest to least to mountain sucker, reside shiner, Utah chub, cutthroat trout, and rainbow trout and carp. Selectively and safety indices for Utah chub compared with the two species of …
