Ecosystem transformation involves the emergence of persistent ecological or social–ecological systems that diverge, dramatically and irreversibly, from prior ecosystem structure and function. Such transformations are occurring at increasing rates across the planet in response to changes in climate, land use, and other factors. Consequently, a dynamic view of ecosystem processes that accommodates rapid, irreversible change will be critical for effectively conserving fish, wildlife, and other natural resources, and maintaining ecosystem services. However, managing ecosystems toward states with novel structure and function is an inherently unpredictable and difficult task. Managers navigating ecosystem transformation can benefit from considering broader objectives, beyond a …

Isotopic Palaeoecology Of Northern Great Plains Bison During The Holocene, Gaimi Davies, Blake Mccann, Jay Sturdevant, Fern Swenson, Igor V. Ovtchinnikov
Isotopic Palaeoecology Of Northern Great Plains Bison During The Holocene, Gaimi Davies, Blake Mccann, Jay Sturdevant, Fern Swenson, Igor V. Ovtchinnikov
Biology Faculty Publications
Bison (Bison bison) are one of the few terrestrial megafauna to survive the transition into the Holocene and provide a unique opportunity to study a species on a broad spatiotemporal scale. Today, bison are primarily managed in small and isolated herds with little known about their ancestral ecology. We studied the carbon and nitrogen isotopes of Northern Great Plains bison from the terminal Pleistocene and throughout the Holocene to gain insight into their paleoecology. This time span is contemporary with the first population bottleneck experienced by bison at the end of the Pleistocene and includes the second bottleneck …

Late Summer Glacial Meltwater Contributions To Bull Lake Creek Stream Flow And Water Quality, Wind River Range, Wyoming, Usa, Jeffrey Vanlooy, Gregory S. Vandeberg
Earth System Science and Policy Faculty Publications
The Wind River Range in Wyoming contains more glacial ice than any other location within the USA’s Rocky Mountain states of Colorado, Idaho, Montana, and Wyoming. Bull Lake Creek watershed in the southeast portion of the range contains five major (0.6–1.5 km2) glaciers along with numerous smaller glaciers that contribute to the Wind River. Field measurements were made of discharge from the Knife Point and Bull Lake Glaciers to determine the contribution of glacial meltwater to the river system. Water samples were collected and analyzed for stable isotopes, major ions, nutrients, and selected trace elements. Meltwater from the two glaciers …

Comparing Source Rock Maturity With Pore Size Distribution And Fluid Saturation In The Bakken-Three Forks Petroleum System, Williston Basin, North Dakota, Adedoyin Suleman Adeyilola
Comparing Source Rock Maturity With Pore Size Distribution And Fluid Saturation In The Bakken-Three Forks Petroleum System, Williston Basin, North Dakota, Adedoyin Suleman Adeyilola
Theses and Dissertations
With the continuous demand for fossil fuel and advancement in technology, the unconventional petroleum resources have come into limelight. The Devonian Three Forks Formation consisting of carbonate and clastic sediments is an unconventional oil accumulation
containing about 3.73 billion barrels of technically recoverable oil. However, understanding rock properties of the various lithofacies and fluid saturation is still challenging.
The petroleum prospectivity was evaluated by integrating organic maturity and hydrocarbon generation with porosity distribution and fluid saturation in the Ambrose field and adjacent fields. The organic maturity was done with a programmed pyrolysis analysis (Source
Rock Analyzer) using samples taken at …

Spatially Distributed Pothole Depth Data, Xuefeng Michael Chu Ph.D, Kendall Grimm, Mohsen Tahmasebi Nasab, Ning Wang, Mohammad Hadi Bazrkar, Lan Zeng, Matt Lee, Jamal Ghauri, Dillon Ekholm, Jackie Arntson, Libby Kruse, Jared Swanberg
Datasets
The locations of our surveyed potholes are located in the Cottonwood Lake Study Area (CLSA) of the USGS Northern Prairie Wildlife Research Center (NPWRC). RiverSurveyor M9 by SonTec (RiverSurveyor M9) was utilized to obtain spatially distributed pothole depth data. This way a modified DEM was created which reflected the pothole bathymetry rather than the water surface elevations. The M9 records water depths using multi-band multiple acoustic frequencies from the vertical beam which “pings” the pothole bed while simultaneously collecting the GPS coordinates of each “ping”. High ping rates ensure robust data collection and high resolution. The vertical beam can measure …
