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...

Genetic diversity of populations of Astragalus oniciformis using inter-simple sequence repeat (ISSR) markers

Creator:: Alexander, J. Andrew
Abstract:: Astragalus oniciformis Barneby is a xerophyte of the sagebrush deserts of central Idaho. It is a narrow endemic of the upper Snake River Plains where it inhabits stabilized, aeolian sand deposits over Quaternary basalt flows. The objective of this study was to determine the levels and distribution of genetic differentiation...

The Alexander polynomial

Creator:: Scherich, Nancy
Abstract:: The Alexander polynomial is a well understood classical knot invariant with interesting symmetry properties and recent applications in knot Floer homology. There are many different ways to compute the Alexander polynomial, some involving algebraic techniques and others more geometric or combinatorial approaches. This is an interesting example of how different...

Life-Cycle and Playability Analysis of Natural Turfgrass and Synthetic Infill Playing Surfaces Under Field Conditions

Creator:: Daviscourt Brian L.
Abstract:: The perception of a long-term cost advantage of synthetic infill turf systems relative to natural grass systems has contributed to a rise in their popularity in the USA. However, few comprehensive cost assessments of natural grass and synthetic infill systems exist. There are also no studies looking at interactions between...

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...

Verifying safe use of a thinner aluminum scattering chamber for fission physics

Creator:: Porter, Eben, Jr.
Abstract:: This thesis describes calculations done to determine the radiation hazard of the current Prompt Gamma Neutron Activation Analysis (PGNAA) scattering chamber at the Oregon State TRIGA Reactor (OSTR) and compare it to the amount that would be given off by a new thin-walled chamber design. These calculations were completed with...

A morphometric analysis of geographic variation within Sorex monticolus

Creator:: Alexander, Lois F.
Abstract:: Shrews previously recognized as Sorex monticolus were classified into two species (one with 14 subspecies, the other monotypic) on the basis of a morphometric analysis of 3610 individuals from throughout their range. Sorex m. neomexicanus has been recognized previously as a subspecies of Sorex monticolus but is recognized herein as...

Investigating Alternative Irrigation Strategies and Sources for the Cool-Humid Willamette Valley

Creator:: Olsen, Conner J.
Abstract:: Rising human populations and climate change are putting increasing demands on our already-limited freshwater sources. In response to these concerns, homeowners and municipalities have been encouraged to replace turfgrass – a plant with relatively high irrigation needs – with drought-tolerant plants that do not require frequent irrigation. However, the many...

Measurement and modeling the physical controls of snowmelt in the Pacific Northwest

Creator:: Mazurkiewicz, Adam B.
Abstract:: The physical controls of snowmelt in the Pacific Northwest (PNW) are poorly understood. While there have been numerous field and modeling investigations at the plot and watershed scale, few studies have identified how the snow energy balance (EB) components vary in importance both spatially and temporally. The identification of how...

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...
