No-tillage winter wheat (Triticum aestivum L.) grown in a
wheat-fallow cropping system has consistently produced lower grain
yields than conventionally tilled soils in the semiarid Pacific
Northwest. A 2-year study was conducted in a long-term tillage trial
at Moro, OR to determine factors responsible for differences in wheat
growth and...
Data from 592 litters of pigs farrowed and raised at the
Oregon Agricultural Experiment Station at Corvallis from the spring
of 1961 through the spring of 1968 were analyzed for effects of year
and season of birth, breed, sex, inbreeding and age of dam on
measures of fecundity, growth rate...
The objective of this study is to assess the quantitative
genetic structure of fitness characters in Tribolium confusum
flour beetles. Estimates of genetic variation and covariation for a
series of fitness components (two measurements of survival,
larval weight, development time, fecundity, and female
productivity) were obtained from two populations of...
Ecological communities are connected in space and time through the transfer of energy, materials, and organisms, together known as ecological subsidies. These ecological subsidies can have substantial effects on community structure, function, and services, especially when the connections are between communities with contrasting productivity. At the ocean-land interface, low productivity...
The scientific way of knowing, which results in tremendous advancements in our society, heavily depends on the use of mathematics. Given that math touches nearly every aspect of peoples’ lives in different ways, it is critical that today’s students and tomorrow’s citizens have a solid understanding of math. Unfortunately, a...
The etiology of canine gallbladder mucocele (GBM) has not yet been identified. However, several studies
have linked GBM in dogs to particular breeds (Shetland Sheepdogs are commonly implicated), concurrent endocrine disease
(hyperadrenocorticism and/or hypothyroidism), and a mutation in the canine ABCB4 gene (ABCB4 1583_1584G), particularly
in Shetland Sheepdogs. The current...
Interactions between children and the frail elderly can benefit both generations. Children can gain an understanding of
aging and develop meaningful relationships with older persons. Frail elders can enjoy the happiness and satisfaction of a
relationship with a child.
