Dead and dying Ceanothus sanguineus, C. velutinus, and C. integerrimus plants grown in a native plant nursery in Oregon for landscape restoration were reported in 2011. Plants were wilted with stem lesions above necrotic roots. Using selective media (Hansen et al. 2012), twelve similar Phytophthora isolates were obtained. DNA sequences...
Exercise-induced menstrual dysfunction (ExMD) is prevalent (6-79%) in active women and may result from low energy availability. Unfavorable lipid profiles have been reported in women with ExMD; low energy intake may also increase risk for poor nutritional status. PURPOSE: To compare nutritional status (diet, blood) and lipid profiles in active...
Douglas-fir (DF, Pseudotsuga menziesii) is the most important forest tree in Oregon and is the second most valuable conifer in New Zealand. Phytophthora pluvialis was described (Reeser et al. 2013) from mixed evergreen forests in southwest Oregon. It was subsequently identified as the cause of red needle cast of radiata...

Worldwide measurements of nearly 130C3 species covering all
major plant functional types are analysed in conjunction with
model simulations to determine the effects of mesophyll
conductance (gm) on photosynthetic parameters and their
relationships estimated from A/Ci curves. We find that an
assumption of infinite gm results in up to 75%...
