The Diet of the Galapagos Hawk (Buteo galapagoensis) Before and After Goat Eradication

Creator:: Jaramillo, Maricruz, Donaghy-Cannon, Michelle, Vargas, F. Hernán, and Parker, Patricia G.
Abstract:: Eradication is often the preferred method of invasive species management on islands; however, its consequences may affect native communities. Feral goats (Capra hircus), donkeys (Equus asinus), and pigs (Sus scrofa) were eradicated from Santiago Island in the Galapagos Archipelago by 2005. Because feral goats were the dominant herbivores on Santiago...

Nesting pair density and abundance of ferruginous hawks (Buteo regalis) and golden eagles (Aquila chrysaetos) from aerial surveys in Wyoming

Creator:: Olson, Lucretia E., Oakleaf, Robert J., Squires, John R., Wallace, Zachary P., and Kennedy, Patricia L.
Abstract:: Raptors that inhabit sagebrush steppe and grassland ecosystems in the western United States may be threatened by continued loss and modification of their habitat due to energy development, conversion to agriculture, and human encroachment. Actions to protect these species are hampered by a lack of reliable data on such basic...

Home Range and Habitat Selection by Northern Spotted Owls on the Eastern Slope of the Cascade Mountains, Washington

Creator:: Forsman, Eric D., Sovern, Stan G., Taylor, Margaret, and Biswell, Brian L.
Abstract:: We used radiotelemetry to study space use and habitat selection of 16 Northern Spotted Owls (Strix occidentalis caurina) on the eastern slope of the Cascade Mountains, Washington, U.S.A., in 1989–1990. We used a geographical information system (GIS) and aerial photo interpretation of digital orthophotos to assign owl locations a value...

Survival Rates of Northern Spotted Owls in Post-fire Landscapes of Southwest Oregon

Creator:: Clark, Darren A., Anthony, Robert G., and Andrews, Lawrence S.
Abstract:: We estimated annual survival rates (S) of 23 radio-marked Northern Spotted Owls (Strix occidentalis caurina) at the Quartz and Timbered Rock burns and adjacent areas in southwest Oregon. We used known-fate models in program MARK to test for differences in survival among three groups (owls dwelling inside of burned areas,...

Association of Sex, Fledging Date, and Sibling Relationships with Post-Fledging Movements of Burrowing Owls in a Nonmigratory Population in the Imperial Valley, California

Creator:: Catlin, Daniel H. and Rosenberg, Daniel K.
Abstract:: Natal dispersal is an important driver of population and colonization dynamics, yet factors that affect timing and distance of post-fledging movements are poorly understood. We studied post-fledging movements of 34 (12 male and 22 female) juvenile Burrowing Owls (Athene cunicularia) between June 2002 and April 2003, in a nonmigratory population...

Influence of Food Limitation on Reproductive Performance of Burrowing Owls

Creator:: Haley, Katherin L. and Rosenberg, Daniel K.
Abstract:: Reproductive strategies of birds are shaped by patterns of food supply, yet empirical evidence of the consequences and mechanisms of food limitation on reproductive performance is inconsistent, probably due to variable responses from species of differing life-history strategies. We tested the hypothesis that food supplementation would increase reproductive rates of...

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...

Greater decision-making competence is associated with greater expected-value sensitivity, but not overall risk taking: an examination of concurrent validity

Creator:: Parker, Andrew M. and Weller, Joshua A.
Abstract:: Decision-making competence reflects individual differences in the susceptibility to committing decision-making errors, measured using tasks common from behavioral decision research (e.g., framing effects, under/overconfidence, following decision rules). Prior research demonstrates that those with higher decision-making competence report lower incidence of health-risking and antisocial behaviors, but there has been less focus...

Decision-making competence predicts domain-specific risk attitudes

Creator:: Weller, Joshua A., Ceschi, Andrea, and Randolph, Caleb
Abstract:: Decision-making competence (DMC) reflects individual differences in rational responding across several classic behavioral decision-making tasks. Although it has been associated with real-world risk behavior, less is known about the degree to which DMC contributes to specific components of risk attitudes. Utilizing a psychological risk-return framework, we examined the associations between...

Microbial responses to changes in flow status in temporary headwater streams: a cross-system comparison

Creator:: Febria, Catherine M., Hosen, Jacob D., Crump, Byron C., Palmer, Margaret A., and Williams, D. Dudley
Abstract:: Microbial communities are responsible for the bulk of biogeochemical processing in temporary headwater streams, yet there is still relatively little known about how community structure and function respond to periodic drying. Moreover, the ability to sample temporary habitats can be a logistical challenge due to the limited capability to measure...
