Emperor geese (Anser canagicus) are exposed to a diversity of influenza A viruses, are infected during the non-breeding period and contribute to intercontinental viral dispersal
Andrew M. Ramey, Brian D. Uher-Koch, Andrew B. Reeves, Joel A. Schmutz, Rebecca L. Poulson, David E. Stallknecht
2019, Transboundary and Emerging Diseases (66) 1958-1970
Emperor geese (Anser canagicus) are endemic to coastal areas within Beringia and have previously been found to have antibodies to or to be infected with influenza A viruses (IAVs) in Alaska. In this study, we use virological, serological and tracking data to further elucidate the role of emperor geese in...
Genetic variation among island and continental populations of Burrowing Owl (Athene cunicularia) subspecies in North America

2019, American Midland Naturalist (181) 147-169
Sericea lespedeza (Lespedeza cuneata) is a high-tannin, late-season invasive forb species that reduces biodiversity in tallgrass prairie ecosystems. The largest tallgrass prairie remnant exists in the Flint Hills of Kansas and Oklahoma, where the most common grazing management practice involves prescribed fire in early spring followed by intensive stocking with...
Strike-slip fault interactions at Ivanpah Valley, California and Nevada
David M. Miller, Victoria E. Langenheim, Kevin Denton, David A. Ponce
2019, Conference Paper
Ivanpah Valley is flanked by high mountain ranges, and represents one of the most imposing valleys of the eastern Mojave Desert. Its sinuous shape implies a complex origin as does the fact that it is not bordered by prominent range-front normal faults like valleys of the Basin and Range Province....
Movements of immature bald eagles: Implications for bird aircraft strike hazard
Tricia A. Miller, Jeff L Cooper, Adam E. Duerr, Melissa A. Braham, James T. Anderson, Todd E. Katzner
2019, Journal of Wildlife Management (83) 879-892
Bald eagle (Haliaeetus leucocephalus) aircraft strikes have increased dramatically over the last 20 years as their populations have recovered to near historic sizes. Their attraction to airfields and their large body size makes them a danger to aircraft and therefore important to airfield wildlife managers. However, their management is complicated...

Daniel E. McNamara, Mark D. Petersen, Eric M. Thompson, Peter M. Powers, Allison Shumway, Susan M. Hoover, Morgan P. Moschetti, Emily Wolin
2019, Bulletin of the Seismological Society of America (109) 322-335
Ground motion model (GMM) selection and weighting introduces a significant source of uncertainty in United States Geological Survey (USGS) seismic hazard models. The increase in moderate moment magnitude induced earthquakes (Mw 4 to 5.8) in Oklahoma and Kansas since 2009, due to increased wastewater injection related to oil and...

Elizabeth K. Haddon, David M. Miller, Victoria Langenheim, Shannon A. Mahan
2019, Conference Paper, Exploring the ends of eras in the eastern Mojave Desert: 2019 Desert symposium field guide and proceedings
We investigate the dextral Lockhart and Mt. General faults, which are among four active structures in the northwestern portion of the eastern California shear zone (ECSZ). Early mapping depicts the Lockhart and Mt. General faults as discontinuous fault traces that continue northwest of the Lenwood Fault. Recent work indicates that...
