Mapping the thermal climate of the H. J. Andrews Experimental Forest, Oregon

Creator:: Smith, Jonathan W.
Abstract:: The H. J. Andrews Experimental Forest in the Cascades of central Oregon provides a unique opportunity to study spatial climate patterns on a relatively small scale. Historical records at the 64 square-kilometer site provide a spatiallydense 30-year dataset. Thermal regimes at the H. J. Andrews are generally known but the...

The life history of vine maple on the H. J. Andrews Experimental Forest

Creator:: Russel, David Wright
Abstract:: The objective of this study was to examine the life history of vine maple on the H. J. Andrews Experimental Forest. This study was conducted as a part of an I. B. P. general study of understory biomass and productivity. The specific objectives were to 1) estimate the contribution of...

The j-Function and the Monster

Creator:: Scherer, Asa
Abstract:: The first published notion that the j-function was in any way related to the Monster came in 1979, when Conway and Norton noted in [CN79] that each coefficient in the q- expansion of the j-function could be written as a (nontrivial) integral linear combination of the dimensions of irreducible representations...

Quantifying C and N contents and isotope signatures of SOM pools in the H. J. Andrews DIRT plots

Creator:: Keirstead, Heath
Abstract:: The mechanisms governing short- and long-term belowground carbon dynamics need to be understood. As part of a larger project developed to assess the effect of quantity and quality of litter inputs on the rate of soil organic matter (SOM) formation, I examined SOM in the H. J. Andrews Detritus Input...

Effect of adult aquatic insect life history on return to Lookout Creek, H. J. Andrews Experimental Forest, Oregon

Creator:: Farrand, Alexander Mark
Abstract:: Aquatic insects that emerge out of streams to mate represent a potential energy flux to terrestrial food webs. The relative success of an individual aquatic adult insect is whether it survives long enough to produce offspring, i.e. mate and return to the stream to oviposit eggs. Some characteristics of the...

Do vigorous young forests reduce streamflow? Results from up to 54 years of streamflow records in eight paired-watershed experiments in the H. J. Andrews and South Umpqua Experimental Forests

Creator:: Perry, Timothy D.
Abstract:: This study quantified the magnitude and timing of summer streamflow deficits in paired-watershed experiments in the Cascade Range of Oregon where mature and old-growth conifer forests were subjected to clearcutting, patch cutting, and overstory thinning treatments in the 1960s and 1970s. Hydrologic effects of clearcutting, small-patch cutting, and overstory thinning...

Current-feedthrough cancellation technique for current-mode T/H circuits

Creator:: Young, David Y. W.
Abstract:: In this paper, an analysis of the clock-feedthrough effects in switched-current (SI)' circuits will be presented. The clock-feedthrough effects caused by the non-ideal characteristic of MOS switches when they are turned off limit the accuracy of the analog track-and-hold (T/H) circuits. A model to analyze and characterize this effect is...

Evidence of buried particulate organic carbon as foundation for heterotrophic carbon metabolism in the hyporheic zone of a montane headwater stream in the H. J. Andrews Experimental Forest, Oregon, USA

Creator:: Serchan, Satish P.
Abstract:: Streams and rivers play a critical role in global carbon (C) cycling by processing, storing, and transporting C. Headwater streams which make up more than 95% of the length of streams and rivers worldwide have disproportionate influence on fluvial C dynamics. The hyporheic zone (HZ) of headwater streams is a...
