Carter Lake, a freshwater, coastal dune-margin lake,
was sampled at the beginning and end of the summer of 1986
to determine the sediment characteristics and benthic
macroinvertebrate abundance, biomass, variety, and
diversity. The distributions of major benthic habitats were
estimated by snorkeling in June and July, 1986. Water
temperature and...
Coastal Douglas-fir (Pseudotsuga menziesii var menziesii) forests are extensive west of the crest of the Cascade Mountains in Oregon and Washington and are renowned for their productivity, biodiversity, and the ecosystem services they provide. Increasing wildfire activity in recent years including the extensive 2020 Labor Day fires, and a warming...
Forest composition in Paraguay has been in a state of change for the past half century due to land management practices, forest fragmentation, and deforestation for agriculture. How these factors affect dendrological diversity and wood anatomy in Paraguay is not well understood. This thesis documents Paraguayan forest composition on the...
Artificial radionuclides, induced in water used as a coolant in the Hanford reactors, are discharged into the Pacific Ocean by the Columbia River. Gamma-ray spectrometric measurements show that levels of 65Zn decrease in both sediments and benthic animals with distance from the mouth of the river and with depth of...
Modification of microbial electrolysis cells (MECs) by altering the sizes of the anode and the cathode, or their interaction with the liquid stream affects the performance of the MEC, but it remains difficult to quantify how much each change will contribute to the overall performance. Through this study, a method...
Alcoves in some river systems are cooler than the mainstem of the river and
provide thermal refugia for aquatic species. An energy balance and sensitivity analysis on 3 alcoves in the Willamette River, Oregon indicate that alcove size and alcove flux determine the degree to which meteorological conditions affect the...

Just as Pirsig’s (Pirsig, R.M. 1974. Zen and the Art of Motorcycle Maintenance. William Morrow and Company, New York. 412pp.) account of his motorcycle adventure explores the dichotomy of holistic and reductionistic philosophies, so too does a short course in chainsaw safety and tree felling incorporate these seemingly disparate viewpoints...
