  Citation × Citation Citation Abstract Copy Title: Recent geomorphic history in the area of experimental watersheds 1, 2, 3, 9, and 10, H. J. Andrews Forest Author: U.S. International Biological Program. Coniferous Forest Biome, James, Michael E., University of Washington, Swanson, Frederick J. (Frederick John), 1943- Studies in the lower Lookout Creek-Blue River area have revealed a geomorphic history including glaciation and the development of three alluvial surfaces, presently active alluvial cones and older, deeply dissected cone remnants. Results are based on landform mapping, analysis of the types and distributions of surficial sediments, and the distribution of Mazama ash. Presence of the ash makes it possible to date geomorphic features relative to a time horizon about 8,000 years in age. This work has served to identify individual cones which will be studied further to learn the erosional histories of specific watersheds.

Coniferous Forest Biome, Cole, Dale W., University of Washington Intensive studies of the mineral cycling process in young-growth Douglas-fir stands have been in progress at the R. H. Thompson Research Center since 1966. During this time, a substantial body of information has been collected on the amounts, pathways, rates of transfer, and mechanisms that control transfer of elements in the mineral cycling process in this ecosystem. These studies have had two major objectives: (1) to provide information describing the changes in mineral cycling as the stand grows, and (2) to examine the year-to-year variation in the mineral cycling process. More recently, a third objective has been to examine the relation between climatic factors and the various mechanisms that control rates of transfer along the transfer pathways.

  Citation × Citation Citation Abstract Copy Title: Eddy sizes above a forest canopy Author: U.S. International Biological Program. Coniferous Forest Biome, Fritschen, Leo, Farnum, Peter, University of Washington Sixteen propeller anemometers were placed 29 meters above a 45-year-old (approximately) Douglas-fir stand. Correlations between paired anemometers, when viewed as a function of distance between them, showed that eddies up to 5 meters in diameter were common, and indicated that larger eddies up to 9 meters across occur. Partial correlation coefficients between anemometers indicated that eddies are simply connected in cross section. Morning and nighttime data were excluded from analysis because the air was too calm. Results are related to the use of the eddy correlation method of determining atmospheric fluxes and the lack of preferential locations for updrafts or downdrafts above a tree crown.

  Citation × Citation Citation Abstract Copy Title: Grazing and production by zooplankton in lakes of the Cedar River watershed Author: Pederson, G. L., U.S. International Biological Program. Coniferous Forest Biome, Stoll, Richard Kenneth, Welch, E. B. (Eugene B.) Zooplankton grazing rates and life history stage densities for secondary production estimates were determined in three lakes in the Cedar River watershed, Washington. Eight copepod species, seven cladoceran and nine rotifer species were identified in the three lakes. No one species of cladoceran or copepod occurred in all the lakes, but the rotifers are common throughout. Copepods in the lakes showed no clear diet migration, while two cladocerans did migrate. Copepods were most important numerically in the lakes. Some principal members were Diaptomus ashZandi which reached a seasonal maximum adult density of 11/2 (mean of water column) in Lake Sammamish and LimnocaZanus in Chester Morse which reached a maximum of 0.7/2. Two Diaptomus species are Important in Findley Lake. Densities averaged about 10 times greater in Sammamish than in the two oligotrophic lakes. Data on population dynamics from the egg ratio technique are given for the common cladocerans in the three lakes. Grazing of phytoplankton by zooplankton stimulated photosynthetic carbon uptake in the light in excess of 200 percent over ungrazed populations. Phytoplankton loss rates from grazing ranged from 0.002 to 0.268 pg chi a/ animal day. Feeding was found to be maximum at low concentrations of algae. These rates account for from 2-247 percent of the average growing season productivity in the lakes. Net plankton (>500 were seldom grazed and since that size fraction and algal mass in general increased with mean productivity and nutrient content in the lakes such decreasing efficiency in food transfer is seen as a major effect of eutrophication.

Andrews Experimental Forest : a partial list of collections from fall 1970 to spring 1972 Author: U.S. International Biological Program. Coniferous Forest Biome, Rhoades, Frederick Mast, University of Washington The fleshy carpophores of fungi fruiling, on soil and litter were collected from watersheds 2, 3, and 10, IBP sites located in the H.J. Andrews Experimental Forest near Blue River, Oregon (122° W, 44° N). No effort was made to systematize collections: all carpophores in fresh condition seen were taken. Collections were made from October, 1970 to April, 1972; generally, the more fungi fruiting, the more often trips to collect were made. Attempts were made to culture all fungi from fresh and large enough specimens, though only few positive cultures were obtained. Specimens were dried and deposited in the OSU herbarium. In addition, those collections of Dr. James Trappe and Robert Fogel, made from the Andrews, are included in the list. I would like to aknowledge the help of Dr. D. E. Stuntz and Dr. Alexander Smith in identification of some collections. Needless to say this list is hardly complete; it is presented with the expectation that changes, additions and deletions will be sent to the author, by those who know the fungal flora and have made collections in the Andrews and nearby.
