A catchment-scale assessment of stream temperature response to contemporary forest harvesting in the Oregon Coast Range

Creator:: Kevin Bladon, Nicholas Cook, Jeffery Light, and Catalina Segura
Abstract:: Historical forest harvesting practices were reviewed in the original Alsea Watershed Study where they found increased energy loading to the stream and produced higher stream temperatures. This was an important early research site that led to the development of contemporary forest management practices to protect water quality and fish habitat...

Interactions between sodium N-methyldithiocarbamate and Douglas-fir heartwood

Creator:: Miller, D. B. and Morrell, Jeffrey J.
Abstract:: Vapam(r) (NaMDC) is the fumigant most commonly used to arrest and control decay of utility poles. While volatile fungitoxins are detectable only 1 to 2 years after treatment, poles treated with Vapam(r) remain free of decay fungi for 6 to 17 years. Vapam(r) decomposes to produce volatile fungicides as well...

N₂-Fixing Red Alder Indirectly Accelerates Ecosystem Nitrogen Cycling

Creator:: Perakis, Steven S., Matkins, Joselin J., and Hibbs, David E.
Abstract:: Symbiotic N₂-fixing tree species can accelerate ecosystem N dynamics through decomposition feedbacks via both direct and indirect pathways. Direct pathways include the production of readily decomposed leaf litter and increased N supply to decomposers, whereas indirect pathways include increased tissue N and altered detrital dynamics of non-fixing vegetation. To evaluate...

Controlling decay fungi in Douglas-fir heartwood with pelletized sodium n-methyldithiocarbamate

Creator:: Sexton, Camille M., Morrell, Jeffrey J., and Newbill, Mark A.
Abstract:: A small block test was used in assessing whether pelletized sodium n-methyldithiocarbamate (NaMDC) would decompose and produce methylisothiocyanate (MITC) and thereby eliminate Antrodia carbonica colonies from Douglas-fir heartwood. Also evaluated were the effects of wood moisture content, dosage, incubation period, pH level, and presence of copper sulfate on percentage of...

Abstract:: Studies of the effects of various chemicals on fungal growth are difficult to perform on filamentous fungi because of the difficulty of observing the protoplasm through the rigid hyphal wall, and because most activity occurs in the region near the hyphal tip. However, hyphae can be exposed to certain enzymes...

Reconciling estimates of the contemporary North American carbon balance among terrestrial biosphere models, atmospheric inversions, and a new approach for estimating net ecosystem exchange from inventory-based data

Abstract:: We develop an approach for estimating net ecosystem exchange (NEE) using inventory-based information over North America (NA) for a recent 7-year period (ca. 2000–2006). The approach notably retains information on the spatial distribution of NEE, or the vertical exchange between land and atmosphere of all non-fossil fuel sources and sinks...
