Automated reconstruction of tree and canopy structure for modeling the internal canopy radiation regime

Creator:: van Leeuwen, Martin, Coops, Nicholas C., Hilker, Thomas, Wulder, Michael A., Newnham, Glenn J., and Culvenor, Darius S.
Abstract:: Understanding canopy radiation regimes is critical to successfully modeling vegetation growth and function. For instance, the vertical distribution of photosynthetically active radiation (PAR) affects vegetation growth, informative upon carbon and energy cycling. Availing upon advances in information capture and computing power, geometrically explicit modeling of forest structure becomes increasingly possible....

Remote sensing of transpiration and heat fluxes using multi-angle observations

Creator:: Hilker, Thomas, Hall, Forrest G., Coops, Nicholas C., Collatz, James G., Black, T. Andrew, Tucker, Compton J., Sellers, Piers J., and Grant, Nicholas
Abstract:: Surface energy balance is a major determinant of land surface temperature and the Earth's climate. To date, there is no approach that can produce effective, physically consistent, global and multi-decadal energy–water flux data over land. Net radiation (R[subscript n]) can be quantified regionally using satellite retrievals of surface reflectance and...

Prediction of Wood Fiber Attributes from LiDAR-Derived Forest Canopy Indicators

Creator:: Hilker, Thomas, Frazer, Gordon W., Coops, Nicholas C., Wulder, Michael A., Newnham, Glenn J., Stewart, James D., van Leeuwen, Martin, and Culvenor, Darius S.
Abstract:: We investigated the potential use of airborne light detection and ranging (LiDAR) data to predict key wood fiber properties from extrinsic indicators in lodgepole pine leading forest stands located in the foothills of central Alberta, Canada. Six wood fiber attributes (wood density, cell perimeter, cell coarseness, mature fiber length, microfibril...

Estimating forest productivity in the eastern Siskiyou Mountains of southwestern Oregon using a satellite driven process model, 3-PGS

Creator:: Coops, N. C. and Waring, R. H.
Abstract:: The 3-PGS (physiological principles for predicting growth using satellite data) model generates monthly estimates of transpiration, photosynthesis, and net primary production (NPP), the latter derived as a fixed proportion (0.47) of gross photosynthesis. To assess the reliability of a simplified process model (3-PGS) to predict the productive capacity of coniferous...

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...

The roles of nearest neighbor methods in imputing missing data in forest inventory and monitoring databases

Creator:: Eskelson, Bianca N.I., Temesgen, Hailemariam, Lemay, Valerie, Barrett, Tara M., Crookston, Nicholas L., and Hudak, Andrew T.
Abstract:: Almost universally, forest inventory and monitoring databases are incomplete, ranging from missing data for only a few records and a few variables, common for small land areas, to missing data for many observations and many variables, common for large land areas. For a wide variety of applications, nearest neighbor (NN)...

Australasian sequestrate fungi 18: Solioccasus polychromus gen. & sp. nov., a richly colored, tropical to subtropical, hypogeous fungus

Creator:: Trappe, James M., Castellano, Michael A., Halling, Roy E., Osmundson, Todd W., Binder, Manfred, Fechner, Nigel, and Malajczuk, Nicholas
Abstract:: Solioccasus polychromus gen. & sp. nov., the most brightly colored hypogeous fungus known, is described from Papua New Guinea and tropical northern Australia south into subtropical forests along the Queensland coast and coastal mountains to near Brisbane. Phylogenetic analysis of molecular data places it as a sister genus to Bothia...

A comparison of selected parametric and imputation methods for estimating snag density and snag quality attributes

Creator:: Eskelson, B. N. I., Temesgen, Hailemariam, and Hagar, J. C.
Abstract:: Snags (standing dead trees) are an essential structural component of forests. Because wildlife use of snags depends on size and decay stage, snag density estimation without any information about snag quality attributes is of little value for wildlife management decision makers. Little work has been done to develop models that...

Alsea watershed study revisited: unpublished temperature datasets from pre-harvest 2006 to 2010

Creator:: Bladon, Kevin, Cook, Nicholas, Light, Jeffery, Segura, Catalina, Skaugset, Arne, Hale, Cody, Leer, David, Garland, Tina, Simmons, Amy, Irving, Alex, Ice, George G., Danehy, Robert, Bousquet, Terry, Cook, Diana, Napack, Jan, Campbell, David, Louch, Jeff, Stednick, John, and Menk, Matthew
Abstract:: These data contain temperature readings from dataloggers launched in Deer Creek, Flynn Creek, and Needle Branch from 2006 to 2010. These loggers were apart of the Alsea Watershed Revisisted Study Revisited articles, but the data was incomplete due to logging gaps, temperature spikes, or other issues. The "Thermistor Functionality" datasets...
