Determination and prediction of rare earth element eeochemical associations in acid mine drainage treatment wastes
B.C. Hedin, Charles A. Cravotta III, M.Y. Stuckman, C.L. Lopano, R.C. Capo, R.S. Hedin
2022, Conference Paper, Proceedings of the 12th International Conference on Acid Rock Drainage
Acid mine drainage (AMD) has been proposed by various researchers as a novel source of rare earth elements (REE), a group of elements that include critical metals for clean energy and modern technologies. REE tend to be sequestered in the Fe-Al-Mn-rich solids produced during the treatment of AMD. These solids...
Maintaining wetland ecosystem services in a changing climate
W. Carter Johnson, Glenn R. Guntenspergen
2022, Book chapter, Soil hydrology in a changing climate
A changing climate is causing challenges for soil and water management in many parts of the world. Current soil management practices need to be redesigned to effectively address present and future fluctuating climates. Soil Hydrology in a Changing Climate explores how soil management practices impact soil hydrological characteristics, and how we...

Audrey Harris, Matthew P. Fairchild, Sara J. Oyler-McCance, Jennifer A. Fike, Christopher Kennedy, Dana Winkleman, Yoichiro Kanno
2022, Conference Paper, Proceedings of the Wild Trout XIII Symposium
We studied gene flow of non-native Brook Trout Salvelinus fontinalis in a 60-km section of continuous stream network in the upper Cache la Poudre River basin, where a large-scale reclamation effort to restore federally threatened Greenback Cutthroat Trout Oncorhynchus clarkii stomias (GBCT) is taking place. This effort—the Poudre Headwaters Project—represents...
Effects of megafire on woody species in the mixed-grass prairie
Matthias W. Sirch, Daniel S. Sullins, Nicholas J. Parker, David A. Haukos, John D. Kraft, Christian A. Hagen, Kent A. Fricke
2022, Prairie Naturalist (54) 11-23
Lack of fire in contemporary grasslands has contributed to the invasion of woody plants that can survive low-intensity fire upon maturity, but knowledge of the effects of megafires (>40,000 ha) on grassland tree mortality is limited. We used remote sensing and ground surveys to estimate tree canopy cover change and...
Conservation genetics and wild trout: Evolving opportunities to support management
David C. Kazyak, Shannon L. White, N. Mamoozadeh, John Hargrove, Mariah Meek
2022, Conference Paper, Proceedings of the Wild Trout XIII Symposium
It is increasingly apparent that our planet is undergoing rapid, unprecedented environmental change. These changes are already impacting wild trout populations, leading to declines in occupancy and abundance across increasingly fragmented landscapes. Many changes are projected to intensify in the coming decades, which are likely to be crucial to the...
Increasing the efficiency and power of camera traps for EDRR & ecological monitoring
Gretchen Erika Anderson, Amy A. Yackel Adams
2022, Newsletter
Invasive species are an ever-growing concern for Florida, especially in important environments like the Greater Everglades Ecosystem. One of the best ways to fight back against invasives is the use of the “Early Detection, Rapid Response” (EDRR) system. The earlier we can detect the presence of a nonnative species, and...
Benefits of genetic data for the design of Brook Trout translocation efforts
Shannon L. White, Thomas C Johnson, Jacob M Rash, Barbara A. Lubinski, David C. Kazyak
2022, Conference Paper, Proceedings of the Wild Trout XIII Symposium
With wild trout populations in decline, many conservation practitioners are evaluating the feasibility of incorporating reintroduction and genetic rescue into management frameworks. As interest in these conservation tools continues to grow, so too has the need for rigorous science to evaluate translocation success and improve the efficacy of future efforts....

Supplemental vegetation monitoring plots at Badlands National Park to accelerate learning of the Annual Brome Adaptive Management (ABAM) model
Amy Symstad
2022, Report
The annual Brome Adaptive Management (ABAM) project is a consortium of seven parks in the Northern Great Plains working together to better understand how to control invasive annual grasses (including Bromus species) through an adaptive management approach. This approach is supported by a quantitative model that uses current data from...
Osmoregulation and acid-base balance.
Stephen D. McCormick, Eric T. Schultz, Colin Brauner
2022, Book chapter, Methods for fish biology
Maintaining relatively constant levels of internal cellular ions is critical to the normal function of all animals. For many organisms this is achieved primarily by regulating the ion and acid-base composition of the blood within narrow limits. This understanding of the importance of “le milieu interior,” first espoused by Claude...
Natives bite back! Are Burmese pythons beginning to encounter the resilience of the Everglades Ecosystem?
Andrea Faye Currylow
2022, Newsletter
Burmese pythons (Python bivittatus) is a large, invasive reptile known in Florida for its devastating impacts on native species in the Greater Everglades Ecosystem. Several organizations and individuals are taking action to research and/or remove the snakes, including the U.S. Geological Survey (USGS). Since 2018, scientists from USGS’s Fort Collins...

2022, Report
These 2 workshops were held in response to interest generated from sessions on the use of simulated earthquake ground motions at the 2020 and 2021 Consortium of Organizations for Strong Motion Observation Systems (COSMOS) Technical Sessions. The discussions at the Technical Sessions highlighted desires to promote the use of simulated...

2022, Environmental Science: Water Research & Technology (8) 1408-1422
Wastewater effluent-dominated streams are becoming increasingly common worldwide, including in temperate regions, with potential impacts on ecological systems and drinking water sources. We recently quantified the occurrence/spatiotemporal dynamics of pharmaceutical mixtures in a representative temperate-region wastewater effluent-dominated stream (Muddy Creek, Iowa) under baseflow conditions and characterized relevant fate processes. Herein,...
Atmospheric circulation drivers of extreme high water level events at Foggy Island Bay, Alaska
Peter A. Bieniek, Li H. Erikson, Jeremy L. Kasper
2022, Atmosphere (13)
The northern coast of Alaska is experiencing significant climatic change enhancing hazards from reduced sea ice and increased coastal erosion. This same region is home to offshore oil/gas activities. Foggy Island Bay is one region along the Beaufort Sea coast with planned offshore oil/gas development that will need to account...

Using a grid-search approach to validate the Graves-Pitarka broadband simulation method
Robert Graves
2022, Earth, Planets and Space (74)
This work assesses the ability of the Graves–Pitarka simulation approach to reproduce observed ground motions for 12 California and Baja California earthquakes. A total of 240 realizations are computed for each earthquake and compared with recorded strong motions from near-fault sites. In addition to spatial variability in slip, each realization...
Effects of release techniques on parent-reared whooping cranes in the eastern migratory population
Hillary L. Thompson, M. Susanna Mann, Marianne Wellington, Kim H. Boardman, Glenn H. Olsen
2022, Proceedings of the North American Crane Workshop (15) 53-71
Reintroduction of an Eastern Migratory Population (EMP) of whooping cranes (Grus americana) in the United States by release of captive-reared individuals began in 2001. As of 2020, the EMP has approximately 21 breeding pairs and has had limited recruitment of wild-hatched individuals, thus captive-reared juveniles continue...

Matthew J. Young, Frederick V. Feyrer, Collin Smith, Dennis A. Valentine
2022, San Francisco Estuary and Watershed Science (20)
Non-native predatory fish strongly impact aquatic communities, and their impacts can be exacerbated by anthropogenic habitat alterations. Loss of natural habitat and restoration actions reversing habitat loss can modify relationships between non-native predators and prey. Predicting how these relationships will change is...

2022, Ecotoxicology (31) 1536-1553
Decades of poor reproductive success and young-of-the-year survival, combined with adult mortality events, have led to a decline in the smallmouth bass (SMB; Micropterus dolomieu) population in sections of the Potomac River. Previous studies have identified numerous biologic and environmental stressors associated with negative effects on SMB...
