Cattle use of perennial streams and associated riparian areas on a northeastern Oregon landscape
Stream and riparian health is a major concern for state and federal land management agencies that are charged with oversight of extensive land holdings in the mountain west of the United States. Several federal agencies ...
Reliability of Yield Mapping System for Estimating Perennial Ryegrass Seed Yield
Seed yield is an important factor to any farmer. Most farmers recognize that yield will vary within a field due to many factors, but they are unaware of the actual magnitude of the yield variability. Yield mapping is a ...
Cattle use of off-stream water developments across a northeastern Oregon landscape
Water developments have been considered a fundamental tool for dispersing livestock and reducing livestock impact on riparian and aquatic habitats associated with perennial streams. Quantifying the efficacy of water ...
Effects of Wolf Presence on Daily Travel Distance of Range Cattle
The presence of graywolves (Canis lupus) can directly and indirectly affect beef cattle (Bos taurus) production on rangelands of the Northern Rocky Mountains. While fairly extensive knowledge exists for the direct effects ...
Long-run evaluation of fertilization strategies for dryland wheat in Northcentral Oregon: Simulation analysis
Farmers commonly apply fixed ‘blind’ quantities of nitrogen fertilizer during the fallow or at seeding in rainfed winter wheat-fallow systems in Northcentral Oregon, an area characterized by high year-to-year variation in ...
Native forb response to sulfometuron methyl on medusahead-invaded rangeland in Eastern Oregon
invaded rangelands throughout the western USA. Medusahead is an aggressive competitor that crowds out native plants and reduces forage for wildlife and livestock. Sulfometuron methyl is a sulfonylurea herbicide used to ...
Predicting Spatial Risk of Wolf-Cattle Encounters and Depredation
Spatial variability in terrain, vegetation, and other features affect cattle and wildlife distribution on mountainous grazing lands of the western United States. Yet we have a poor understanding of how this spatial variability ...
Design and Analysis of Delay-Tolerant Sensor Networks for Monitoring and Tracking Free-Roaming Animals
This paper is concerned with the design and analysis of delay-tolerant networks (DTNs) deployed for free-roaming animal monitoring, wherein information is either transmitted or carried to static access-points by the animals ...
Effect of population size on the estimation of QTL: a test using resistance to barley stripe rust
The limited population sizes used in many quantitative trait locus (QTL) detection experiments can lead to underestimation of QTL number, overestimation of QTL effects, and failure to quantify QTL interactions. We used the ...
Monitoring Restoration Impacts to Endemic Plant Communities in Soil Inclusions of Arid Environments
Slickspots are soil inclusions with unique loamy soils that provide habitats for many endemic plants worldwide, including those within sagebrush steppe. Sagebrush-dominated communities are declining and require restoration, ...
