Modeling the dynamics of lahars that originate as landslides on the west side of Mount Rainier, Washington
David L. George, Richard M. Iverson, Charles M. Cannon
2022, Open-File Report 2021-1118
Large lahars pose substantial threats to people and property downstream from Mount Rainier volcano in Washington State. Geologic evidence indicates that these threats exist even during the absence of volcanic activity and that the threats are highest in the densely populated Puyallup and Nisqually River valleys on the west side...
Invertibility aware integration of static and time-series data: An application to lake temperature modeling
Kshitij Tayal, Xiaowei Jia, Rahul Ghosh, Jared Willard, Jordan Read, Vipin Kumar
2022, Conference Paper, Proceedings of the 2022 SIAM International Conference on Data Mining
Accurate predictions of water temperature are the foundation for many decisions and regulations, with direct impacts on water quality, fishery yields, and power production. Building accurate broad-scale models for lake temperature prediction remains challenging in practice due to the variability in the data distribution across different lake systems monitored by...
Ungulate migration in a changing climate—An initial assessment of climate impacts, management priorities, and science needs
Katherine C. Malpeli
2022, Circular 1493
Executive SummaryMigratory behavior among ungulates in the Western United States occurs in response to changing forage quality and quantity, weather patterns, and predation risk. As snow melts and vegetation green-up begins in late spring and early summer, many migratory ungulates leave their winter range and move to higher elevation summer...

Re-evaluating invasive species in degraded ecosystems: A case study of red-eared slider turtles as partial ecological analogs
Marc Dupuis-Desormeaux, Jeffrey E. Lovich, J. Whitfield Gibbons
2022, Discover Sustainability (3)
Exotic species are often vilified as "bad" without consideration of the potential they have for contributing to ecological functions in degraded ecosystems. The red-eared slider turtle (RES) has been disparaged as one of the worst invasive species. Based on this review, we suggest that RES contribute some ecosystem functions in...

Protocols for collecting and processing macroinvertebrates from the benthos and water column in depressional wetlands
Breanna R. Keith, Jake D. Carleen, Danelle M. Larson, Michael J. Anteau, Megan J. Fitzpatrick
2022, Open-File Report 2022-1029
Freshwater aquatic macroinvertebrates are key links in food webs and nutrient cycles, and thus often serve as biological indicators of ecosystem health. Macroinvertebrate investigations in research and monitoring require consistent and reliable field and laboratory procedures. Comprehensive standard operating procedures for sampling macroinvertebrates from depressional wetlands, which can range from...
Utah and Landsat
U.S. Geological Survey
2022, Fact Sheet 2022-3023
Utah’s list of notable features runs long, but scenery rises to the top. The Colorado River does not simply run through southeastern Utah; it meanders through steep canyons of the eroded sedimentary rock that colors the sweeping vistas of the Colorado Plateau. Stone arches, spires, hoodoos, cliffs, and bridges in...
Hydraulics of freshwater mussel habitat in select reaches of the Big River, Missouri
Maura O. Roberts, Robert B. Jacobson, Susannah O. Erwin
2022, Scientific Investigations Report 2022-5002
The Big River is a tributary to the Meramec River in south-central Missouri. It drains an area that has been historically one of the largest lead producers in the world, and associated mine wastes have contaminated sediments in much of the river corridor. This study investigated hydraulic conditions in four...

Detection and characterization of coastal tidal wetland change in the northeastern US using Landsat time series
Xiucheng Yang, Zhe Zhu, Shirley Qiu, Kevin D. Kroeger, Zhiliang Zhu, Scott Covington
2022, Remote Sensing of Environment (276)
Coastal tidal wetlands are highly altered ecosystems exposed to substantial risk due to widespread and frequent land-use change coupled with sea-level rise, leading to disrupted hydrologic and ecologic functions and ultimately, significant reduction in climate resiliency. Knowing where and when the...
Integration of satellite-based optical and synthetic aperture radar imagery to estimate winter cover crop performance in cereal grasses
Jyoti Jennewein, Brian T. Lamb, W. Dean Hively, Alison Thieme, Resham Thapa, Avi Goldsmith, Phillip Dennison
2022, Remote Sensing (14)
The magnitude of ecosystem services provided by winter cover crops is linked to their performance (i.e., biomass and associated nitrogen content, forage quality, and fractional ground cover), although few studies quantify these characteristics across the landscape. Remote sensing can produce landscape-level assessments of cover crop performance. However,...

2022, Hydrology (9)
The Okaloosa darter (Etheostoma okaloosae) is a diminutive, perch-like, benthic fish that inhabits only six small, clear, and shallow creek systems that flow almost entirely within Eglin Air Force Base in the panhandle of northwest Florida. Listed as Endangered by the U.S. Fish and Wildlife Service (USFWS) in 1973,...

Nedal T. Nassar, Graham W. Lederer, Jamie L. Brainard, Abraham J. Padilla, Joseph D. Lessard
2022, Environmental Science & Technology (56) 6710-6721
The quantity of ore mined and waste rock (i.e., overburden or barren rock) removed to produce a refined unit of a mineral commodity, its rock-to-metal ratio (RMR), is an important metric for understanding mine wastes and environmental burdens. In this analysis, we provide a comprehensive examination of RMRs for 25...
Prairie wetlands as sources or sinks of nitrous oxide: Effects of land use and hydrology
Brian Tangen, Sheel Bansal
2022, Agricultural and Forest Meteorology (320)
National and global greenhouse gas (GHG) budgets are continually being refined as data become available. Primary sources of the potent GHG nitrous oxide (N2O) include agricultural soil management and burning of fossil fuels, but comprehensive N2O budgets also incorporate less prominent factors such as wetlands. Freshwater wetland GHG flux estimates,...

Burgin, Margaret Zimmer, Thibault Datry, Walter K. Dodds, C. Nathan Jones, Meryl Mimms, Catherin Franklin, John C. Hammond, Samuel Zipper, Adam S Ward, Katie H. Costigan, Hylke Beck, Julian D. Olden
2022, Nature Sustainability (5) 586-592
Knowing where and when rivers flow is paramount to managing freshwater ecosystems. Yet stream gauging stations are distributed sparsely across rivers globally and may not capture the diversity of fluvial network properties and anthropogenic influences. Here we evaluate the placement bias of a global stream gauge dataset on its representation...
Plant community context controls short- vs. medium-term effects of pre-emergent herbicides on target and non-target species after fire
Brynne E. Lazarus, Matthew J. Germino
2022, Applied Vegetation Science (25)
Questions: Selective herbicide application is a common restoration strategy to control exotic invaders that interfere with native plant recovery after wildfire. Whether spraying with preemergent or bioherbicides releases native plants from competition with exotics (“spray-and-release” strategy) and can make communities resistant to re-invasion by exotic annual grasses (e.g., cheatgrass, medusahead), without...
Washington and Landsat
U.S. Geological Survey
2022, Fact Sheet 2022-3021
Washington is a State of untamed wonders, from its ruggedly beautiful coastline to the volcanic peaks of the Cascades. “The Evergreen State” is also a State of contrasts, home to rainforests west of the Cascades and deserts to the east. Half of Washington is forested, and its orchards grow more...

Lack of tree fecundity data across climatic gradients precludes the analysis of how seed supply contributes to global variation in forest regeneration and biotic interactions responsible for biodiversity. A global synthesis of raw seedproduction data shows a 250-fold increase in seed abundance from cold-dry to warm-wet climates, driven primarily by...
A suction pump sampler for invertebrate drift detects exceptionally high concentrations of small invertebrates that drift nets miss
Jason R. Neuswanger, Erik R. Schoen, Mark S. Wipfli, Carol J. Volk, James W. Savereide
2022, Hydrobiologia (849) 2077-2089
Invertebrate drift is a key process in riverine ecosystems controlling aquatic invertebrate movement, distribution, and availability to fish as prey. However, accurately sampling drift across a wide range of invertebrate sizes is difficult because small invertebrates slip through coarse-mesh drift nets, and fine mesh clogs more easily, which reduces filtration...
