Changes in the federal farm program, in rainfall pattern and quantity, and
increased incidence of herbicide resistant weeds and diseases have generated
increased interest in spring grains in the Pacific Northwest. However, spring grains
have traditionally been treated as minor crops in this region, thus little research has
been done...
Sudangrass (Sorghum bicolor L. Moench) was introduced into Texas in the early 1900s and soon became established as an important pasture crop.
After its introduction, many improved varieties were developed. They have greater disease resistance, sweeter stems, less toxic chemical content, and more leaves than previous varieties. This is the...
As important ecological cornerstones, coral reefs face threats from a myriad of sources, such as global climate change, and importantly, disease, the latter often as a result of microbial pathogens. An understudied group of major corals, fire corals, and their even less understood microbiome present an opportunity to learn more...
Sorghums (Sorghum bicolor) are warm-season grasses native to Africa. They were introduced into the United States in the 17th century. They are grown primarily under dryland conditions or with limited irrigation in the semiarid
southwest and the Great Plains. Grain sorghums generally are cultivated in areas that are too hot...
Safflower (Carthamus tinctorius L) is a herbaceous annual and a member of the
Asteraceae/Compositae (sunflower) family. It is native to parts of Asia, the Middle East, and Africa. It was grown mainly for its flowers, which were used in making dyes for clothing and food. Today, it is grown mainly...
Alfalfa (Medicago sativa L), called queen of forages, is the most important and productive forage crop in North America. It is the most widely adapted legume known. It was introduced to the western United States in the 1850s, and it is well suited to the dry climates and irrigated soils...
In some legislative bodies, the use of terms like climate change and global warming is frequently seen as taboo. In the United States, voters who identify as right-leaning have reported little concern about the environment or climate change. This lack of interest is mirrored by Republican legislators who often publicly...
Tsunamis have the potential to inflict severe damage and loss of life in coastal communities. Structures known as vertical evacuation buildings provide an alternative evacuation site for communities living in relatively flat, coastal regions with inadequate sources of high ground for evacuation. Design of these structures balances risk and economy,...
This investigation was designed to investigate the use of an answer-until-correct procedure on multiple-choice quizzes in an independent study mathematics course. This procedure was compared to the standard multiple-choice procedure with respect to student achievement, student anxiety, and test reliability. Using the answer-until-correct procedure students were made immediately aware of...
This study evaluates the functional organization of stream fish assemblages in response to streamflow factors and biotic interactions across a range of spatial scale. The study area for this project includes 109 stream reaches located on tributaries to the upper Missouri River in the northern Great Plains. Fish distribution data...
