Lidar-derived canopy architecture predicts brown creeper occupancy of two western coniferous forests

Creator:: Vogeler, Jody C., Hudak, Andrew T., Vierling, Lee A., and Vierling, Kerri T.
Abstract:: In western conifer-dominated forests where the abundance of old-growth stands is decreasing, species such as the Brown Creeper (Certhia americana) may be useful as indicator species for monitoring the health of old-growth systems because they are strongly associated with habitat characteristics associated with old growth and are especially sensitive to...

Carbon concentration of standing and downed woody detritus: Effects of tree taxa, decay class, position, and tissue type

Creator:: Harmon, Mark E., Fasth, Becky, Woodall, Christopher W., and Sexton, Jay
Abstract:: The degree to which carbon concentration (CC) of woody detritus varies by tree taxa, stage of decay, tissue type (i.e., bark versus wood), and vertical orientation was examined in samples of 60 tree species from the Northern Hemisphere. The mean CC of 257 study samples was 49.3% with a range...

Acceptance, Acceptability, and Trust for Sagebrush Restoration Options in the Great Basin: A Longitudinal Perspective

Creator:: Gordon, Ryan, Brunson, Mark W., and Shindler, Bruce
Abstract:: In surveys of residents in three urban and three rural locations in the Great Basin we examined the social acceptability of six management practices showing promise for restoring sagebrush-dominated rangelands. Unlike most studies of range management perceptions that have relied on single measurements, we used longitudinal data from a questionnaire...

A Landsat time series approach to characterize bark beetle and defoliator impacts on tree mortality and surface fuels in conifer forests

Creator:: Meigs, Garrett W., Kennedy, Robert E., and Cohen, Warren B.
Abstract:: Insects are important forest disturbance agents, and mapping their effects on tree mortality and surface fuels represents a critical research challenge. Although various remote sensing approaches have been developed to monitor insect impacts, most studies have focused on single insect agents or single locations and have not related observed changes...

Prey Suitability and Phenology of Leucopis spp. (Diptera: Chamaemyiidae) Associated With Hemlock Woolly Adelgid (Hemiptera: Adelgidae) in the Pacific Northwest

Creator:: Grubin, Sarah M., Ross, Darrell W., and Wallin, Kimberly F.
Abstract:: Leucopis spp. (Diptera: Chamaemyiidae) from the Pacific Northwest previously were identified as potential biological control agents for the hemlock woolly adelgid, Adelges tsugae Annand (Hemiptera: Adelgidae), in the eastern United States. We collected Leucopis spp. larvae from A. tsugae infested western hemlocks in Oregon and Washington and reared them on...

The Rise of the Mesopredator

Creator:: Prugh, Laura R., Stoner, Chantal J., Epps, Clinton W., Bean, William T., Ripple, William J., Laliberte, Andrea S., and Brashares, Justin S.
Abstract:: Apex predators have experienced catastrophic declines throughout the world as a result of human persecution and habitat loss. These collapses in top predator populations are commonly associated with dramatic increases in the abundance of smaller predators. Known as “mesopredator release,” this trophic interaction has been recorded across a range of...

Spatial patterns and trends of summertime low cloudiness for the Pacific Northwest, 1996-2017

Creator:: Dye, Alex W., Rastogi, Bharat, Clemesha, Rachel E. S., Kim, John B., Samelson, Roger M., Still, Christopher J., and Williams, A. Park
Abstract:: Summertime low clouds are common in the Pacific Northwest (PNW), but spatiotemporal patterns have not been characterized. We show the first maps of low cloudiness for the western PNW and North Pacific Ocean using a 22‐year satellite‐derived record of monthly mean low cloudiness frequency for May through September and supplemented...

Characterizing Community Forests in the United States

Creator:: Hajjar, Reem, McGinley, Kathleen, Charnley, Susan, Frey, Gregory E., Hovis, Meredith, Cubbage, Frederick W., Schelhas, John, and Kornhauser, Kailey
Abstract:: Research on community forests, primarily governed and managed by local forest users, in the United States is limited, despite their growth in numbers over the past decade. We conducted a survey to inventory CFs in the U.S., and better understand their ownership and governance structures, management objectives, benefits, and financing....

Use of change-point detection for friction–velocity threshold evaluation in eddy-covariance studies

Creator:: Barr, A. G., Richardson, A. D., Hollinger, D. Y., Papale, D., Arain, M. A., Black, T. A., Bohrer, G., Dragoni, D., Fischer, M. L., Gu, L., Law, B. E., Margolis, H. A., McCaughey, J. H., Munger, J. W., Oechel, W., and Schaeffer, K.
Abstract:: The eddy-covariance method often underestimates fluxes under stable, low-wind conditions at night when turbulence is not well developed. The most common approach to resolve the problem of nighttime flux underestimation is to identify and remove the deficit periods using friction-velocity (u*) threshold filters (u*[superscript Th]). This study modifies an accepted...
