Changes in the 2 H and 18 O of atmospheric water vapour provide information for integrating aspects of gas exchange within forest canopies. In this study, we show that diurnal fluctuations in the oxygen isotope ratio ( δ 18 O) as high as 4‰ were observed for water vapour ( δ 18 O vp ) above and within an old-growth coniferous forest in the Pacific Northwest region of the United States. Values o...

An overview is presented on recent ecosystem studies in the Medicine Bow National Forest and Yellowstone National Park. Most of the research has focused on lodgepole pine forests. Hydrology, leaf area development, decomposition, nutrient dynamics, soil chemistry, landscape ecology, and the effects of tree harvest, fire, and mountain pitie beetles have been emphasized. The subalpine elevations o...

thereby representing a novel time course for desensitization. Our starting dose was higher than the 0.02-mg starting dose administered to a non-HIV patient during fluconazole desensitization; however, our initial dose was equal to or less than other protocols involving HIV-infected patients.1,5,6 Given this patient’s HIV status, we used a cautious desensitization approach (eg, dose escalation e...
