Changes in aquatic vegetation cover following lock closure on the Illinois Waterway from 2019 – 2021
Andrew C. Strassman
2022, Completion Report LTRMP-2019AER7
Over the summer of 2020, the Illinois Waterway was closed to complete maintenance on lock chambers along the Illinois River. This closure restricted inter-pool vessel traffic along the river and potentially changed habitat characteristics for aquatic vegetation establishment and growth. To assess if patterns of vegetation establishment and growth changed...

Kelly O. Maloney, Claire Buchanan, Rikke Jepsen, Kevin P. Krause, Matthew J. Cashman, Benjamin P. Gressler, John A. Young, Matthias Schmid
2022, Journal of Environmental Management (322)
Anthropogenic alterations have resulted in widespread degradation of stream conditions. To aid in stream restoration and management, baseline estimates of conditions and improved explanation of factors driving their degradation are needed. We used random forests to model biological conditions using a benthic macroinvertebrate index of biotic...

Maya Groner, Paul Hershberger, Steven C. Fradkin, Carla M. Conway, Aine C. Hawthorn, Maureen K. Purcell
2022, Diseases of Aquatic Organisms (151) 1-9
ABSTRACT: Nuclear inclusion X (NIX), the etiological agent of bacterial gill disease in Pacific razor clams Siliqua patula, was associated with host mortality events in coastal Washington State, USA, during the mid-1980s. Ongoing observations of truncated razor clam size distributions in Kalaloch Beach, Washington, raised concerns that NIX continues to...
Stream macroinvertebrate reintroductions: A cautionary approach for restored urban streams
Sandra M. Clinton, Jacqueline Hartman, Kate H. Macneale, Allison H. Roy
2022, Freshwater Science (41) 507-520
Macroinvertebrate assemblages often remain depauperate in physically restored urban streams despite efforts to improve habitat conditions and increase species abundance and diversity. The lack of biological recovery may be due to a lack of a natural, nearby source of colonists, and this has inspired researchers and practitioners to reintroduce macroinvertebrates...

Wetland CH4 emissions are among the most uncertain components of the global CH4 budget. The complex nature of wetland CH4 processes makes it challenging to identify causal relationships for improving our understanding and predictability of CH4 emissions. In this study, we used the flux measurements of CH4 from eddy covariance towers (30 sites from 4...

Ken Eng, David M. Wolock
2022, Scientific Investigations Report 2022-5058
Few regional or national scale studies have evaluated machine learning approaches for predicting streamflow metrics at ungaged locations. Most such studies are limited by the number of dimensions of the streamflow regime investigated. This study, in contrast, provides a comprehensive evaluation of the streamflow regime based on three widely available...

Stanley Paul Mordensky, John Lipor, Erick R. Burns, Cary Ruth Lindsey
2022, Conference Paper, Using the earth to save the earth
Modern advancements in science and engineering are built upon multidisciplinary projects that bring experts together from different fields. Within their respective disciplines, researchers rely on precise terminology for specific ideas, principles, methods, and theories. Hence, the potential for miscommunication is substantial, especially when common words have been adopted by one...

Logan Arnold, Mark David Scheuerell, T.B. Isaksen
2022, Atmosphere (13)
Extreme heat is one of the most important pathways illustrating the connection between climate and human health, and climate change is expected to exacerbate this public health issue. This study first used a case-crossover analysis to characterize the historical (1980–2018) association between summertime heat and non-traumatic mortality in Washington State....
