In this paper we introduce the iWatch web crawler, a tool designed to catalogue and analyze online data practices and the use of privacy related indicators and technologies. Our goal in developing iWatch was to make possible a new type of analysis of trends, the impact of legislation on practices,...
The Cooperative Institute for Oceanographic Satellite Studies
(CIOSS) partners with The Science and Math Investigative Learning
Experiences (SMILE) Program to bring ocean sciences and satellite
oceanography to high school students and teachers around the
state of Oregon. This study was conducted as a formative program
assessment during the third year...
Management and conservation of rangelands are increasingly concerned with maintaining productivity, species composition, and diversity of native plant communities. We estimated aboveground annual productivity, species composition, and diversity of a native bunchgrass type community across 1152, 0.5 m2 plots at The Nature Conservancy’s Zumwalt Prairie Preserve in northeastern Oregon. Standing...
The estimation of standing crop is important in the management of rangeland resources. Direct measurements by clipping, drying, and weighing of herbaceous vegetation are time-consuming and labor-intensive. Therefore, non-destructive methods for efficiently and accurately estimating standing crop are needed in rangeland forage management. We assessed a visual obstruction (VO) technique...
In spring time, animals, goats and sheep in particular, prefer to eat flowers Pulsatilla multifida, and Iris tenifolia. Pulsatilla's flower contains sugar 20.33, starch 6.71, cellulose 19.15, lignin 6.50, and acid detergent fibre (ADF) 24.88, neutral detergent fibre (NDF) 32.55, hemicellulose 7.67, and protein 14.27 percent. Dry matter digestibility (DMD),...
Vegetation and geographic region including forest steppe in Khangai Range, mountain steppe in Mongol Altai, desert steppe in the Great Lakes Depression, the Valley of the Lakes and Gobi Altai Mountains and Zuungar and Trans-Altai Gobi were covered by the scope of the investigation. 181 samples of 123 plant species...
We assessed a photographic technique to estimate shrub yield and utilization of common snowberry, snowbrush, and heart-leafed willow found in mixed-conifer rangelands. We determined the correlation between green leaf area size (LA) and forage yield (Y) and compared plant utilization estimated by photographic technique (ULA) to actual utilization (UY) values....
