Conservation practitioners are increasingly looking to species translocations as a tool to recover imperiled taxa. Quantitative predictions of where animals are likely to move when released into new areas would allow managers to better address the social, institutional, and ecological dimensions of conservation translocations. Using >5 million California condor (Gymnogyps...

Kelley Sterle, Wesley Kitlasten, Eric D. Morway, Richard G. Niswonger, Loretta Singletary
2019, Fact Sheet 19-10
What does climate change mean for snow-fed river basins?Climate change poses unique challenges in snow-fed river basins across the western United States because the majority of water supply originates as snow (Dettinger, Udall, & Georgakakos, 2015). In the Sierra Nevada, recent observations include changes in snow accumulation and snowmelt, and...

Implications of aggregating daily production data on estimates of ultimate recovery from horizontal hydraulically fractured Bakken oil wells
T. C. Coburn, Emil D. Attanasi
2019, Conference Paper, 20th Annual conference of the International Association for Mathematical Geosciences (IAMG2019)
The level to which data are aggregated can impact analytical and predictive modeling results. In this short paper we discuss some of our findings regarding the impacts of data aggregation on estimating change points in the production profiles of horizontal hydraulically fractured Bakken oil wells. Change points occur when production...

Off-channel waterbodies in the Middle Mississippi River: A pilot investigation
Molly Sobotka, John West
2019, Report
Off-channel and floodplain water bodies are important components of large river ecosystems while rare within the Middle Mississippi River. The lack of these habitats likely influences water quality, nutrient processing, and communities of organisms. In early 2016 a major flood event breached two levees south of Cape Girardeau, MO resulting...
