Abstract:: These high resolution (5x5-meter pixel) categorical models of land cover were created by training random forest classification models on RapidEye (Planet Labs Inc.) satellite spectral data for each year and then predicting those models across the landscape. Training data were created by visually interpreting random plots over high resolution NAIP...

Abstract:: NASA’s ICESat-2 satellite, which launched in 2018, carries the Advanced Topographic Laser Altimeter System (ATLAS), a green-wavelength, photon-counting lidar. While ICESat-2’s primary mission focuses on measurement of elevation of ice sheets, glaciers, sea ice, and vegetation, ATLAS has also proven remarkably effective at measurement of bathymetry, or water depths. However,...

Abstract:: Processes that influence habitat selection in landscapes involve the interaction of habitat composition and configuration and are particularly important for species with complex life cycles. We assessed the relative influence of landscape spatial processes and local habitat characteristics on patterns in the distribution and abundance of spawning steelhead (Oncorhynchus mykiss),...

Abstract:: Powdery mildew of hop (Podosphaera macularis) may cause economic loss due to reductions in cone yield and quality. Quantitative estimates of crop damage from powdery mildew remain poorly characterized, especially the effect of late season disease management on crop yield and quality. Field studies in Washington State evaluated cone yield,...

Creator:: Hamilton, Christopher M., Martinuzzi, Sebastian, Plantinga, Andrew J., Radeloff, Volker C., Lewis, David J., Thogmartin, Wayne E., Heglund, Patricia J., and Pidgeon, Anna M.
Abstract:: Land-use change around protected areas can reduce their effective size and limit their ability to conserve biodiversity because land-use change alters ecological processes and the ability of organisms to move freely among protected areas. The goal of our analysis was to inform conservation planning efforts for a nationwide network of...

Creator:: Wallace, Zachary P., Kennedy, Patricia L., Squires, John R., Oakleaf, Robert J., Olson, Lucretia E., and Dugger, Katie M.
Abstract:: Grassland and shrubland birds are declining globally due in part to anthropogenic habitat modification. Because population performance of these species is also influenced by non-anthropogenic factors, it is important to incorporate all relevant ecological drivers into demographic models. We used design-based sampling and occupancy models to test relationships of environmental...
