Landsat-based monitoring of annual wetland change in the Willamette Valley of Oregon, USA from 1972 to 2012

Creator:: Fickas, Kate C., Cohen, Warren B., and Yang, Zhiqiang
Abstract:: n Oregon’s Willamette Valley, remaining wetlands are at high risk to loss and degradation from agricultural activity and urbanization. With an increased need for fine temporal-scale monitoring of sensitive wetlands, we used annual Landsat MSS and TM/ETM+ images from 1972 to 2012 to manually interpret loss, gain, and type conversion...

Landscape characteristics and coho salmon (Oncorhynchus kisutch) distributions: explaining abundance versus occupancy

Creator:: Steel, E. A., Jensen, D. W., Burnett, K. M., Christiansen, K., Firman, J. C., Feist, B. E., Anlauf, K. J., and Larsen, D. P.
Abstract:: Distribution of fishes, both occupancy and abundance, is often correlated with landscape-scale characteristics (e.g., geology, climate, and human disturbance). Understanding these relationships is essential for effective conservation of depressed populations. We used landscape characteristics to explain the distribution of coho salmon (Oncorhynchus kisutch) in the Oregon Plan data set, one...

Competitive Interactions and Resource Partitioning Between Northern Spotted Owls and Barred Owls in Western Oregon

Creator:: Wiens, J. David, Anthony, Robert G., and Forsman, Eric D.
Abstract:: The federally threatened northern spotted owl (Strix occidentalis caurina) is the focus of intensive conservation efforts that have led to much forested land being reserved as habitat for the owl and associated wildlife species throughout the Pacific Northwest of the United States. Recently, however, a relatively new threat to spotted...

Management, Morphological, and Environmental Factors Influencing Douglas-Fir Bark Furrows in the Oregon Coast Range

Creator:: Sheridan, Christopher D., Puettmann, Klaus J., Huso, Manuela M.P., Hagar, Joan C., and Falk, Kristen R.
Abstract:: Many land managers in the Pacific Northwest have the goal of increasing late-successional forest structures. Despite the documented importance of Douglas-fir tree bark structure in forested ecosystems, little is known about factors influencing bark development and how foresters can manage development. This study investigated the relative importance of tree size,...

Modeling Marbled Murrelet (Brachyramphus marmoratus) Habitat Using LiDAR-Derived Canopy Data

Creator:: Hagar, Joan C., Eskelson, Bianca N. I., Haggerty, Patricia K., Nelson, S. Kim, and Vesely, David G.
Abstract:: LiDAR (Light Detection And Ranging) is an emerging remote-sensing tool that can provide fine-scale data describing vertical complexity of vegetation relevant to species that are responsive to forest structure. We used LiDAR data to estimate occupancy probability for the federally threatened marbled murrelet (Brachyramphus marmoratus) in the Oregon Coast Range...

Sex matters: Otolith shape and genomic variation in deacon rockfish (Sebastes diaconus)

Creator:: Vaux, Felix, Rasmuson, Leif K., Kautzi, Lisa A., Rankin, Polly S., Blume, Matthew T. O., Lawrence, Kelly A., Bohn, Sandra, and O'Malley, Kathleen G.
Abstract:: Little is known about intraspecific variation within the deacon rockfish (Sebastes di‐ aconus), a recently described species found in the northeast Pacific Ocean. We in‐ vestigated population structure among fish sampled from two nearshore reefs (Siletz Reef and Seal Rock) and one offshore site (Stonewall Bank) within a <50‐km2 area...

The effects of habitat, climate, and Barred Owls on long-term demography of Northern Spotted Owls

Abstract:: Estimates of species' vital rates and an understanding of the factors affecting those parameters over time and space can provide crucial information for management and conservation. We used mark–recapture, reproductive output, and territory occupancy data collected during 1985–2013 to evaluate population processes of Northern Spotted Owls (Strix occidentalis caurina) in...

Evaluating carbon storage, timber harvest, and habitat possibilities for a Western Cascades (USA) forest landscape

Creator:: Kline, Jeffrey D., Harmon, Mark E., Spies, Thomas A., Morzillo, Anita T., Pabst, Robert J., McComb, Brenda C., Schnekenburger, Frank, Olsen, Keith A., Csuti, Blair, and Vogeler, Jody C.
Abstract:: Forest policymakers and managers have long sought ways to evaluate the capability of forest landscapes to jointly produce timber, habitat, and other ecosystem services in response to forest management. Currently, carbon is of particular interest as policies for increasing carbon storage on federal lands are being proposed. However, a challenge...

Maturation characteristics and life-history strategies of the Pacific lamprey, Entosphenus tridentatus

Creator:: Clemens, Benjamin J., van de Wetering, Stan, Sower, Stacia A., and Schreck, Carl B.
Abstract:: Lampreys (Petromyzontiformes) have persisted over millennia and now suffer a recent decline in abundance. Complex life histories may have factored in their persistence; anthropogenic perturbations in their demise. The complexity of life histories of lampreys is not understood, particularly for the anadromous Pacific lamprey, Entosphenus tridentatus Gairdner, 1836. Our goals...
