Northern spotted owl reproductive rates (version 3)

Creator:: Rockweit, Jeremy T., Jenkins, Julianna M. A., Hines, James E., Nichols, James D., Dugger, Katie M., Franklin, Alan B., Carlson, Peter C., Kendall, William L., Lesmeister, Damon B., McCafferty, Christopher, Ackers, Steven H., Andrews, L.

David, Wise, Heather, and Yackulic, Charles B.
Abstract:: These datasets were used in the prospective meta-analysis of northern spotted owl reproductive rates over 25 years across 11 study areas located throughout the range of the owl. A multi-state occupancy file was created by collapsing site-specific information on owl reproductive status into bimonthly (2 per month) survey occasions. These...

Greater sage-grouse vital rates after wildfire

Creator:: Foster, Lee J., Dugger, Katie M., Hagen, Christian A., and Budeau, David A.
Abstract:: Greater sage-grouse (Centrocercus urophasianus) have been subject to long-term and continuing declines in population and habitat since European settlement of western North America. Increased wildfire activity constitutes a primary threat to the species in western portions of their range, with documented declines in wildfire-affected populations. Following a 187,000-ha wildfire in...

Roosting Habitat Use and Selection By Northern Spotted Owls During Natal Dispersal

Creator:: Sovern, Stan G., Forsman, Eric D., Dugger, Katie M., and Taylor, Margaret
Abstract:: We studied habitat selection by northern spotted owls (Strix occidentalis caurina) during natal dispersal in Washington State, USA, at both the roost site and landscape scales. We used logistic regression to obtain parameters for an exponential resource selection function based on vegetation attributes in roost and random plots in 76...

Survival and Home-range Size of Northern Spotted Owls in Southwestern Oregon

Creator:: Schilling, Jason W., Dugger, Katie M., and Anthony, Robert G.
Abstract:: In the Klamath province of southwestern Oregon, Northern Spotted Owls (Strix occidentalis caurina) occur in complex, productive forests that historically supported frequent fires of variable severity. However, little is known about the relationships between Spotted Owl survival and home-range size and the characteristics of fire-prone, mixed-conifer forests of the Klamath...

The evolution of mapping habitat for northern spotted owls (Strix occidentalis caurina): A comparison of photo-interpreted, Landsat-based, and lidar-based habitat maps

Creator:: Ackers, Steven H., Davis, Raymond J., Olsen, Keith A., and Dugger, Katie M.
Abstract:: Wildlife habitat mapping has evolved at a rapid pace over the last few decades. Beginning with simple, often subjective, hand-drawn maps, habitat mapping now involves complex species distribution models (SDMs) using mapped predictor variables derived from remotely sensed data. For species that inhabit large geographic areas, remote sensing technology is...

Differences in Adélie Penguin (Pygoscelis adeliae) Chick Growth Rates and Diet

Creator:: Jennings, Scott, Varsani, Arvind, Dugger, Katie M., Ballard, Grant, and Ainley, David G.
Abstract:: Sexually size-dimorphic species must show some difference between the sexes in growth rate and/or length of growing period. Such differences in growth parameters can cause the sexes to be impacted by environmental variability in different ways, and understanding these differences allows a better understanding of patterns in productivity between individuals...

Stable occupancy by breeding hawks (Buteo spp.) over 25 years on a privately managed bunchgrass prairie in northeastern Oregon, USA

Creator:: Kennedy, Patricia L., Bartuszevige, Anne M., Houle, Marcy, Humphrey, Ann B., Dugger, Katie M., and Williams, John
Abstract:: Potential for large prairie remnants to provide habitat for grassland-obligate wildlife may be compromised by nonsustainable range-management practices. In 1979–1980, high nesting densities of 3 species of hawks in the genus Buteo—Ferruginous Hawk (Buteo regalis), Red-tailed Hawk (B. jamaicensis), and Swainson’s Hawk (B. swainsoni)—were documented on the Zumwalt Prairie and...

Population dynamics of mallards breeding in eastern Washington

Creator:: Dugger, Bruce D., Coluccy, John M., Dugger, Katie M., Fox, Trevor T., Kraege, Don, and Petrie, Mark J.
Abstract:: Variation in regional population trends for mallards breeding in the western United States indicates that additional research into factors that influence demographics could contribute to management and understanding the population demographics of mallards across North America. We estimated breeding incidence and adult female, nest, and brood survival in eastern Washington...

Climate Change Winners: Receding Ice Fields Facilitate Colony Expansion and Altered Dynamics in an Adélie Penguin Metapopulation

Creator:: LaRue, Michelle A., Ainley, David G., Swanson, Matt, Dugger, Katie M., Lyver, Phil O'B., Barton, Kerry, and Ballard, Grant
Abstract:: There will be winners and losers as climate change alters the habitats of polar organisms. For an Adelie penguin (Pygoscelis adeliae) colony on Beaufort Island (Beaufort), part of a cluster of colonies in the southern Ross Sea, we report a recent population increase in response to increased nesting habitat as...
