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...

Factors Affecting Incubation Patterns and Sex Roles of Black Oystercatchers in Alaska

Creator:: Spiegel, Caleb S., Haig, Susan M., Goldstein, Michael I., and Huso, Manuela
Abstract:: Studies examining the effects of human disturbance on avian parental behavior and reproductive success are fundamental to bird conservation. However, many such studies fail to also consider the influence of natural threats, a variable environment, and parental roles. Our work examines interactive relationships of cyclical (time of day, tide, temperature,...

Coastal sand dunes of Oregon and Washington

Creator:: Cooper, William Skinner, 1884-
Abstract:: In Part I the environment of the coastal dunes of Oregon and Washington is analyzed. Most of the substratum is a narrow foreland or terrace, in part submerged, that borders the mountain front. Temperature is relatively low in summer and rarely reaches the freezing point in winter. Winter precipitation is...

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...

Nesting ecology of Marbled Murrelets at a remote mainland fjord in southeast Alaska

Creator:: Barbaree, Blake A., Nelson, S. Kim, Dugger, Bruce D., Roby, Daniel D., Carter, Harry R., Whitworth, Darrell L., and Newman, Scott H.
Abstract:: Studying the ecology of endangered species in portions of their range where the population remains abundant can provide fundamental information for conservation planners. We studied nesting by radio-tagged Marbled Murrelets (Brachyramphus marmoratus) during 2007 and 2008 in Port Snettisham, a relatively pristine, remote mainland fjord in southeast Alaska with high...

A Review of Contemporary Methods for the Presentation of Scientific Uncertainty

Creator:: Makinson, K. A., Hamby, D. M., and Edwards, J. A.
Abstract:: Graphical methods for displaying uncertainty are often the most concise and informative way to communicate abstract concepts. Presentation methods currently in use for the display and interpretation of scientific uncertainty are reviewed. Numerous subjective and objective uncertainty display methods are presented, including qualitative assessments, node and arrow diagrams, standard statistical...

Age-specific variation in apparent survival rates of male lesser-prairie-chickens

Creator:: Hagen, Christian A., Pitman, James C., Sandercock, Brett K., Robel, Robert J., and Applegate, Roger D.
Abstract:: We used mark-recapture methods to estimate age-specific apparent survival rates for male Lesser Prairie-Chickens (Tympanuchus pallidicinctus), a gamebird of conservation concern. A total of 311 male prairie-chickens (135 yearlings, 176 adults) were captured and banded during a 5-year study in southwest Kansas. Time-since-marking models were used to estimate apparent survival...

Evaluation of a Workplace Treadmill Desk Intervention: A Randomized Controlled Trial

Creator:: Schuna, John M., Jr., Swift, Damon L., Hendrick, Chelsea A., Duet, Megan T., Johnson, William D., Martin, Corby K., Church, Timothy S., and Tudor-Locke, Catrine
Abstract:: OBJECTIVE: To evaluate the effectiveness of a 3-month treadmill desk intervention in eliciting changes in physical activity and sedentary behavior among overweight/obese office workers. METHODS: A randomized controlled trial was conducted among overweight/obese office workers (n=41; mean age = 40.1 ± 10.1 years) at a private workplace. Participants were randomly...
