Creator:: Lassoie, J. P., U.S. International Biological Program. Coniferous Forest Biome, and University of Washington
Abstract:: Diurnal changes in stem circumference at the 1954 and 1963 internodes of a 22-year-old Douglas-fir were monitored using automated band dendrometers. Determinations of internal tree water potential and estimates of transpiration were used to characterize the water status of the tree. Environmental monitoring included the measurement of air temperature along...

Creator:: Kangur, Rudolf and Oregon State University. Forest Research Laboratory
Abstract:: Data collected from permanent sample plots at medium and high elevations in Oregon's coastal forest clearly indicate that snow damage adversely influences stand development. Sapling stands of western hemlock and Douglas-fir were subjected to severe snow damage above 1,000 feet in the early parts of 1965 and 1966 and above...

Creator:: Waring, Richard H., Running, S. W., Holbo, Harold Richard, Kline, J. R., U.S. International Biological Program. Coniferous Forest Biome, and University of Washington
Abstract:: In the Coniferous Forest Biome, many of the understory as well as dominant plants are evergreen and thus water uptake is a year around process. The flow of water from the soil through plants to the atmosphere affects the entire forest ecosystem. As water is evaporated, it absorbs heat and...

Creator:: Scott, David R. M., Lassoie, J. P., U.S. International Biological Program. Coniferous Forest Biome, and University of Washington
Abstract:: Preliminary results of a comprehensive study of hydraulic fluctuations in Douglas-fir (Pseudotsuga menziesii) stems in response to plant water status and environment are presented. Diurnal changes in stem circumference near DBH of a dominant Douglas-fir were monitored using automated band dendrometers. Measurements of transpiration rate, internal moisture stress and stomata...

Creator:: Scott, David R. M., Lassoie, J. P., U.S. International Biological Program. Coniferous Forest Biome, and University of Washington
Abstract:: During the summer of 1971, diurnal patterns of water status were monitored in Acer circinatum. Measurements of transpiration rate, internal moisture stress, and relative leaf resistance were used to characterize the water status of the tree. For the days examined, the diurnal and seasonal fluctuations of water status in relation...

Abstract:: Measurement of plant moisture stress of 1-2 m understory conifers was made in "reference stands" on the H. J. Andrews Experimental Forest in 1970-1972. Maximum stress each year (measured between midnight and dawn) is closely correlated with the position of each community along one axis of an ordination of the...
