Evaluation Of Methods Used To Improve Grasslands As Ring-Necked Pheasant (Phasianus Colchicus) Brood Habitat, Mandy Orth Jan 2018

Evaluation Of Methods Used To Improve Grasslands As Ring-Necked Pheasant (Phasianus Colchicus) Brood Habitat, Mandy Orth

Electronic Theses and Dissertations

Management practices designed for upland game species often focus on nest survival and hen winter survival due to the importance of these life history stages on population vital rates. However, chick survival is an important component of gallinaceous bird population dynamics, but it is poorly understood and often tends to be overlooked. Ideal brood habitat not only provides open understory for easy movement and canopy cover for protection, but also provides an abundance of arthropod foods for chicks. It has been hypothesized that restricted movement of chicks through thick vegetation in unmanaged grasslands results in lower brood survival rates. Research …


Ischemic Preconditioning Improves Maximal Accumulated Oxygen Deficit In Ncaa Division I Middle-Distance Runners, Emily Paull Jan 2018

Ischemic Preconditioning Improves Maximal Accumulated Oxygen Deficit In Ncaa Division I Middle-Distance Runners, Emily Paull

Electronic Theses and Dissertations

Purpose: There is an ongoing debate concerning whether ischemic preconditioning elicits consistent and meaningful exercise performance benefits.

Application Of Drainage Water Management And Saturated Buffers For Conservation Drainage In South Dakota, Abhinav Sharma Jan 2018

Application Of Drainage Water Management And Saturated Buffers For Conservation Drainage In South Dakota, Abhinav Sharma

Electronic Theses and Dissertations

Edge of field practices such as drainage water management (DWM) and saturated buffers can reduce nutrient transport from croplands to surface waterbodies. DWM uses stackable weir boards in a control structure to manipulate the water table depth throughout the cropping season and reduce the amount of nutrient rich water draining out from the field. Saturated buffers, on the other hand, use a control structure to divert water draining out from the cropland to a vegetative strip via a subsurface tile installed parallel to a waterway. For the saturated buffer systems, a combination of natural denitrification, nitrogen mineralization, and plant uptake …
