2022, Open-File Report 2022-1028
The delta smelt (Hypomesus transpacificus) is a small, euryhaline fish species endemic to the Sacramento–San Joaquin Delta; it is protected under the U.S. and California Endangered Species Acts, and because of declines in population abundance, the delta smelt may be vulnerable to extinction. The California Department of Water Resources (DWR)...

Ethan D. Kyzivat, Laurence C. Smith, Fenix Garcia-Tigreros, Chang Huang, Chao Wang, Theodore Langhorst, Jessica V. Fayne, Merritt E. Harlan, Yuta Ishitsuka, Dongmei Feng, Wayana Dolan, Lincoln H. Pitcher, Kimberly Wickland, Mark Dornblaser, Robert G. Striegl, Tamlin M. Pavelsky, David E. Butman, Colin J. Gleason
2022, Journal of Geophysical Research: Biogeosciences (127)
Areas of lakes that support emergent aquatic vegetation emit disproportionately more methane than open water but are under-represented in upscaled estimates of lake greenhouse gas emissions. These shallow areas are typically less than ∼1.5 m deep and can be detected with synthetic aperture radar (SAR). To assess the importance of lake...

2022, Fact Sheet 2022-3033
Selenium entering the 90-mile long transboundary Koocanusa Reservoir (also called Lake Koocanusa) in southeastern British Columbia, Canada, and northwestern Montana, United States, has been measured at concentrations above State and Federal water-quality and aquatic life standards. The reservoir is within the international Kootenai (or “Kootenay” in Canada) drainage basin, which...
Environmental drivers of cyanobacterial abundance and cyanotoxin production in backwaters of the Upper Mississippi River
Shawn M. Giblin, James H. Larson, Jeremy D. King
2022, River Research and Applications (38) 1115-1128
High densities of cyanobacteria in aquatic ecosystems can cause impacts to ecosystem services because they serve as a poor-quality food resource, produce toxins and can indirectly cause a variety of other negative impacts to water quality. There are many hypotheses about the potential environmental drivers of variation in cyanobacterial abundance...
How beavers are changing Arctic landscapes and Earth’s climate
Jonathan A. O’Donnell, Michael P. Carey, Brett Poulin, Ken Tape, Joshua C. Koch
2022, Frontiers for Young Minds (10)
Beavers build dams that change the way water moves between streams, lakes, and the land. In Alaska, beavers are moving north from the forests into the Arctic tundra. When beavers build dams in the Arctic, they cause frozen soil, called permafrost, to thaw. Scientists are studying how beavers and...

Great Lakes coastal wetlands (GLCW) have been severely degraded by anthropogenic activity over the last several decades despite their critical role in fish production. Many Great Lakes fish species use coastal wetland habitats for spawning, feeding, shelter, and nurseries throughout the year. The goal of our study was to compare...
The protectiveness of aquatic life criteria for threatened or endangered aquatic species: Cadmium in California
Christopher A. Mebane
2022, Preprint
In the United States, conflicts can arise between the processes to derive aquatic life criteria (ALC) for chemicals under the Clean Water Act (CWA) and the evaluation procedures used in Endangered Species Act (ESA) consultations on the protectiveness of those criteria for protected species. This paper examines the roots of,...

Andrew R. Spanjer, Andrew S. Gendaszek, Elyse J. Wulfkuhle, Robert W. Black, Kristin L. Jaeger
2022, PLoS ONE (17)
Pacific salmon and trout populations are affected by timber harvest, the removal and alteration of riparian vegetation, and the resulting physical changes to water quality, temperature, and associated delivery of high-quality terrestrial prey. Juvenile salmon and trout growth, a key predictor of survival, is poorly understood in the context of...

2022, Continental Shelf Research (242)
Erosion rates along Alaska's Beaufort Sea coast, among the highest in the world, are negatively impacting communities, industrial and military infrastructure, and wildlife habitat. Decreasing maximal winter ice extent and increasing summer open water duration and extent in the Beaufort Sea may be making the coast more vulnerable to destructive storm...
Fish ear stones offer climate change clues in Alaska's lakes
Krista K. Bartz, Vanessa R. von Biela, Bryan A. Black, Daniel Young, Peter van der Sleen, Christian E. Zimmerman
2022, Frontiers for Young Minds
Otoliths, also known as ear stones, are small body parts that help fish with hearing and balance. Like tree rings, otoliths form one light and one dark band per year, creating rings. These rings can be measured to understand fish growth. The wider the ring, the greater the growth....
Satellites quantify the spatial extent of cyanobacterial blooms across the United States at multiple scales
Blake Schaeffer, Erin Urquhart, Megan Coffer, Wilson Salls, Richard Stumpf, Keith A. Loftin, P. Jeremy Werdell
2022, Ecological Indicators (140)
Previous studies indicate that cyanobacterial harmful algal bloom (cyanoHAB) frequency, extent, and magnitude have increased globally over the past few decades. However, little quantitative capability is available to assess these metrics of cyanoHABs across broad geographic scales and at regular intervals. Here, the spatial extent was quantified from a cyanobacteria...

Jesse L. De La Cruz, Michael C. True, Hila Taylor, Dorothy Brown, W. Mark Ford
2022, Forests (13)
Reproductively successful and over-wintering populations of the endangered northern long-eared bat (Myotis septentrionalis) have recently been discovered on the Coastal Plain of North Carolina. Empirical data on resource selection within the region is limited, likely hindering management of these coastal forests. Our objectives were to determine roosting home range...

Ellie Broadman, Liam M. Reidy, David Wahl
2022, Anthropocene (38)
Coastal salt marshes and estuaries provide valuable ecosystem services, yet are susceptible to alteration from human activities. Records of past environmental change in these ecosystems can elucidate relationships between human activities, such as land-use practices, and physical and ecological processes, such as sediment accretion...

Gregory E. Noe, Kristina G. Hopkins, Peter Claggett, Edward R. Schenk, Marina J. Metes, Labeeb Ahmed, Thomas Rossiter Doody, Cliff R. Hupp
2022, Environmental Research Letters (17)
Stream geomorphic change is highly spatially variable but critical to landform evolution, human infrastructure, habitat, and watershed pollutant transport. However, measurements and process models of streambank erosion and floodplain deposition and resulting sediment fluxes are currently insufficient to predict these rates in all perennial streams over large...
