Two studies were conducted to determine the effects of zinc (Zn), copper (Cu) and/or selenium (Se) on the humoral immune response of weaned steers fed diets deficient in these minerals. Steers were bled weekly for eight weeks to measure plasma mineral levels. Humoral immune response was measured as antibody response...
Over the past century, life expectancy in the United States has dramatically increased leading to an increasingly aging population with people reaching, and spending more years in ‘old age’. While this unprecedented shift in population demographics represents great strides for humanity, it is not without cost. One consequence of longer...
Research was conducted on the Keating rangelands in north-eastern Oregon to determine the food habits of deer and cattle and
similarity of their diets, and to estimate deer and cattle months of
grazing on both a quantitative and nutritional basis. Data were
collected during the winters of 1978-1979, 1979-1980 and...
Prior to 1986, economic conditions resulted in substantial
unemployment, layoffs, and reduced work time.
Such conditions produced underemployment resulting in significant
income reductions for families. A random sample
of a non-metropolitan Northwest community elicited 137
couples from a variety of incomes. Twenty-one of them
were found to have incomes reduced...
Medusahead (Taeniatherum asperum Nevski), a winter annual native to the Mediterranean region of Eurasia, has infested several million acres of rangeland in the northwestern United States. It has been estimated carrying capacity for domestic livestock on infested ranges has been reduced 75 percent.
The review is a condensed summarization of...
Camelina (Camelina sativa L. Crantz) has received worldwide attention in recent years as a biofuel crop and as a broadleaf option in cereal-based cropping systems. The objective of our 3-year study was to determine camelina seed yield and nitrogen use efficiency (NUE) as affected by six applied nitrogen (N) rates...
There has been keen interest in camelina (Camelina sativa L. Crantz) in recent years due to the unique fatty acid composition of the seed oil for human and animal consumption and, more importantly, the value of the seed oil to provide “green energy” to fuel commercial and military aircraft. The...

Remote-sensing reflectance is easier to interpret for the open ocean than for coastal regions because the optical signals are highly coupled to the phytoplankton (e.g., chlorophyll) concentrations. For estuarine or coastal waters, variable terrigenous colored dissolved organic matter (CDOM), suspended sediments, and bottom reflectance, all factors that do not covary...
