T he heart, lungs, blood, vasculature, and skeletal muscle integrate in a complex way to allow humans to interact with their environment, through locomotion and other forms of physical exercise (1). This interaction becomes challenged in people with the clinical syndrome of heart failure (HF) (2). In addition to the very reasonable desire to live longer, people with HF also want to be able to d...

Cover crops are a suite of non-marketable plant species grown to improve soil quality. They may have additional benefits including reduced weed pressure and enhanced habitat for beneficial arthropods, but they do not provide direct revenue. Integrating sheep grazing for cover crop termination could make the use of cover crops more economically feasible. However, if grazing shifts biological com...

Wyoming big sagebrush (Artemisia tridentata ssp. wyomingensis Beetle & Young) communities frequently are mowed in an attempt to increase perennial herbaceous vegetation. However, there is limited information as to whether expected benefits of mowing are realized when applied to Wyoming big sagebrush communities with intact understory vegetation. We compared vegetation and soil nutrient concentr...

A 2-yr study was conducted to document the influence of selected buffalograss, Buchloë dactyloides (Nuttall) Engelmann, management practices (three mowing heights and five nitrogen levels) on the seasonal abundance of the western chinch bug, Blissus occiduus Barber (Heteroptera: Lygaeidae), and its beneficial arthropods. Vacuum, pitfall, and sticky traps samples were collected every 14 d from t...

by PATRICK M. O'BRIEN Director, Sou theas te rn Region, U S G A Green Sect ion MOST GOLF COURSES like to offer their golfers an artistic contrast between the fairways and roughs, a feature that enhances the natural beauty of each hole. This is true especially if the fairway perimeters are curbed rather than set in a straight line. This feature is termed contour mowing, and it is usually conside...

Pesticide usage on public school grounds is a concern in the U.S. Pacific Northwest. Our objective was to determine how variations primary cultural management practices (mowing, fertilization, and irrigation), absence of herbicide applications, can affect turfgrass quality, weed populations. Three experiments were conducted over three years at OSU Lewis-Brown Horticulture Farm Corvallis, OR mix...
