The inter-relationships among δ¹³C and δ¹⁸O in tree ring cellulose and ring width have the potential to illuminate long-term physiological and environmental information in forest stands that have not been monitored. We examine how within-stand competition and environmental gradients affect ring widths and the stable isotopes of cellulose. We utilize...
Linus Pauling played a key role in creating valence-bond theory, one of two competing theories of the chemical bond that appeared in the first half of the 20th century. While the chemical community preferred his theory over molecular-orbital theory for a number of years, valence-bond theory began to fall into...
Seabirds have often been proposed as environmental indicators. Beached bird data may provide an additional data source and such data is efficacious because it can reliably be collected by volunteers. In addition to anthropogenic factors, such as oil spills, changes in the ocean-atmosphere can affect carcass beaching rate in 3...
Resource managers at the state, federal, and tribal levels make decisions on a weekly to quarterly basis, and fishers operate on a similar timeframe. To determine the potential of a support tool for these efforts, a seasonal forecast system is experimented with here. JISAO’s Seasonal Coastal Ocean Prediction of the...
There is a great deal of evidence that altered sphingolipid metabolism is associated with fumonisin-induced
animal diseases including increased apoptotic and oncotic necrosis, and carcinogenesis in
rodent liver and kidney. The biochemical consequences of fumonisin disruption of sphingolipid
metabolism most likely to alter cell regulation are increased free sphingoid bases...
El ano 2006 representa en dos sentidos una fecha critica para la cuenca del Rio Columbia y para los esfuerzos de recuperacion del salmon y la trucha arcoiris en la region Pacifico Noroeste: el 25 aniversario de la creacion del Consejo para la Conservacion y Poder del Noroeste y el...
