2021, Management of Biological Invasions (12) 96-107
Zequanox® is a biopesticide registered by the U.S. Environmental Protection Agency (USEPA) and the Canadian Pest Management Regulatory Agency for controlling dreissenid mussels with demonstrated selective toxicity. However, some research has indicated that Zequanox may impact the body condition and survival of some non-target species. We assessed avoidance behaviors of...

Rebecca Lynn Brice, Christopher H. Guiterman, Connie A. Woodhouse, Carlee McClellan, Paul Sheppard
2021, Climate Services (22)
Snowpack in the western U.S. is on the decline, largely attributed to increasing temperatures in the region. This is a critical issue for many Native American communities who disproportionately rely on local snow-fed water supplies. In light of a combined ongoing drought...

Andrew L. Birch, Robert Stallard, Sidney A. Bush, Holly R. Barnard
2021, Journal of Hydrology (596)
Despite abundant research documenting that land use/land cover (LULC) have substantial impacts on the hydrology of humid tropical systems, field-based evidence for the physical mechanisms behind these impacts are still lacking. In particular, our understanding of the hydrologic flowpaths that generate runoff in these...

Justine F. Sauvage, Ashton F. Flinders, Arthur J. Spivack, Robert Pockalny, Ann G. Dunlea, Chloe H. Anderson, David Smith, Richard W. Murray, Steven D’Hondt
2021, Nature Communications (12)
Water radiolysis continuously produces H2 and oxidized chemicals in wet sediment and rock. Radiolytic H2 has been identified as the primary electron donor (food) for microorganisms in continental aquifers kilometers below Earth’s surface. Radiolytic products may also be significant for sustaining life in subseafloor sediment and subsurface environments...

Scot K. Izuka, Kolja Rotzoll, Tracy Nishikawa
2021, Scientific Investigations Report 2020-5126
Steady-state numerical groundwater-flow models were constructed for the islands of Kaua‘i, O‘ahu, and Maui to enable quantification of the hydrologic consequences of withdrawals and other stresses that can place limits on groundwater availability. The volcanic aquifers of Hawai‘i supply nearly all drinking water for the islands’ residents, freshwater for diverse...

Machine learning predicted redox conditions in the glacial aquifer system, northern continental United States
Melinda L. Erickson, Sarah M. Elliott, Craig J. Brown, Paul E. Stackelberg, Katherine Marie Ransom, James E. Reddy
2021, Water Resources Research (57)
Groundwater supplies 50% of drinking water worldwide and 30% in the United States. Geogenic and anthropogenic contaminants can, however, compromise water quality, thus limiting groundwater availability. Reduction/oxidation (redox) processes and redox conditions affect groundwater quality by influencing the mobility and transport of common geogenic and anthropogenic contaminants....

Jessica E Brandt, James Roberts, Craig A. Stricker, Holly Rogers, Patricia Nease, Travis S. Schmidt
2021, Environmental Science and Technology (55) 3645-3656
Hydrologic and irrigation regimes mediate the timing of selenium (Se) mobilization to rivers, but the extent to which patterns in Se uptake and trophic transfer through recipient food webs reflect the temporal variation in Se delivery is unknown. We investigated Se mobilization, partitioning, and trophic transfer along approximately 60 river...

The 2017–2027 National Academies' Decadal Survey, Thriving on Our Changing Planet, recommended Surface Biology and Geology (SBG) as a “Designated Targeted Observable” (DO). The SBG DO is based on the need for capabilities to acquire global, high spatial resolution, visible to shortwave...
Salinity changes the dynamics of pyrethroid toxicity in terms of behavioral effects on newly hatched delta smelt larvae
Amelie Segarra, Florian Mauduit, Nermeen Amer, Felix KJ Biefel, Michelle L. Hladik, Richard E Connon, Susanne M. Brander
2021, Toxics (9)
Salinity can interact with organic compounds and modulate their toxicity. Studies have shown that the fraction of pyrethroid insecticides in the aqueous phase increases with increasing salinity, potentially increasing the risk of exposure for aquatic organisms at higher salinities. In the San Francisco Bay Delta (SFBD) estuary,...
Glacier-related outburst floods
John J. Clague, Jim E. O'Connor
2021, Book chapter, Snow and ice-related hazards, risks, and disasters
Water bodies impounded by glaciers, moraines, and ice jams on rivers can drain suddenly, with disastrous downstream consequences. Lakes can form at the margins of an alpine glacier or ice cap, on its surface, or at its base. Smaller pockets of water may also be present within some glaciers....

2021, Open-File Report 2021-1002
Mangrove forests are likely vulnerable to accelerating sea-level rise; however, we lack the tools necessary to understand their future resilience. On the Pacific island of Pohnpei, Federated States of Micronesia, mangroves are habitat to endangered species and provide critical ecosystem services that support local communities. We developed a generalizable modeling...

Paul F. Juckem, J. Jeffrey Starn
2021, Groundwater (59) 710-727
Groundwater flow model construction is often time‐consuming and costly, with development ideally focused on a specific purpose, such as quantifying well capture from water bodies or providing flow fields for simulating advective transport. As environmental challenges evolve, the incentive to re‐purpose existing groundwater flow models may...
