Qunhui Zhang, Jiming Jin, Phaedra E. Budy, Sarah E. Null, Xiaochun Wang, Casey A. Pennock
2021, Geophysical Research Letters (48)
We investigated how lake thermal processes responded to whole lake warming manipulation in an arctic lake through observations and numerical modeling. The warming manipulation was conducted by artificially heating the epilimnion as a proxy for climate warming. We performed numerical modeling with an improved lake scheme based on the Community...

2021, Advances in Limnology (66) 207-223
Understanding ecological relationships among fishes and their environments are important for informing management policies. We conducted a statewide assessment of cisco (Coregonus artedi) in inland lakes of Wisconsin to better understand the status of this pelagic, coldwater forage fish. We then used long-term (2005–2014), standardized walleye (Sander vitreus) survey data...

Michael Wilkie, Laura Tessier, Michael A. Boogaard, Lisa M. O’Connor, Oana Birceanu, Todd B. Steeves, Paul Sullivan
2021, Journal of Great Lakes Research (47) S407-S420
The lampricides TFM and niclosamide are added to streams to control invasive larval sea lamprey (Petromyzon marinus) populations in the Laurentian Great Lakes. Lampricide effectiveness depends upon TFM and niclosamide bioavailability which is influenced by both abiotic and biotic factors. For example, at...

Jill Jenkins, Katherine R. Hartop, Ghadeer Bukhari, Debra E. Howton, Kelly L. Smalling, Scott Mize, Michelle L. Hladik, Darren Johnson, Rassa Dale, Bonnie L. Brown
2021, International Journal of Molecular Sciences (22)
Neonicotinoids (NEO) represent the main class of insecticides currently in use, with thiamethoxam (THX) and clothianidin (CLO) primarily applied agriculturally. With few comprehensive studies having been performed with non-target amphibians, the aim was to investigate potential biomarker responses along an adverse outcome pathway of NEO exposure, whereby...
Dam removal and river restoration
Jeffrey J. Duda, J. Ryan Bellmore
2021, Book chapter, Encyclopedia of Inland Waters
The removal of dams from rivers has become a common and widespread practice in the United States and Europe. Although often initiated by factors like economics and safety, ecosystem restoration is often a desired benefit and outcome of dam removal. We describe the physical and ecological effects that the placement...
Subsurface temperature properties for three types of permeable pavements in cold weather climates and implications for deicer reduction
Mari Danz, Nicolas Buer, William R. Selbig
2021, Water (13)
Permeable pavement has been shown to be an effective urban stormwater management tool although much is still unknown about freeze-thaw responses and the implications for deicer reduction in cold weather climates. Temperature data from the subsurface of three permeable pavement types—interlocking concrete pavers (PICP), concrete (PC), and asphalt (PA)—were...
Subsurface swimming and stationary diving are metabolically cheap in adult Pacific walruses (Odobenus rosmarus divergens)
Alicia Borque-Espinosa, Karyn D. Rode, Diana Ferrero-Fernandex, Anabel Forte, Romana Capaccioni-Azzati, Andreas Fahlman
2021, Journal of Experimental Biology (224)
Walruses rely on sea-ice to efficiently forage and rest between diving bouts while maintaining proximity to prime foraging habitat. Recent declines in summer sea ice have resulted in walruses hauling out on land where they have to travel farther to access productive benthic habitat while...

Leonardo A. Villalon, editor(s)
2021, Book chapter, The Oxford handbook of the African Sahel
In the 1970s and 1980s, the Sahel experienced recurrent drought and famine. Farmers and their development partners reacted to this crisis by developing climate-smart agricultural practices and changes in land use, including water-harvesting techniques to restore degraded land to productivity. In several densely populated parts of the Sahel, farmers began...

Tessa M. Harden, Karen R. Ryberg, Jim E. O'Connor, Jonathan M. Friedman, Julie E. Kiang
2021, Techniques and Methods 4-B6
Paleoflood studies are an effective means of providing specific information on the recurrence and magnitude of rare and large floods. Such information can be combined with systematic flood measurements to better assess the frequency of large floods. Paleoflood data also provide valuable information about the linkages among climate, land...

Streambed scour of salmon (Oncorhynchus spp.) redds in the Sauk River, Northwestern Washington
Andrew S. Gendaszek
2021, Scientific Investigations Report 2021-5133
The autumn and winter flood season of western Washington coincides with the incubation period of many Pacific salmon (Onchorhynchus spp.) populations. During this period, salmon embryos incubating within gravel nests called “redds” are vulnerable to mobilization of surrounding sediment during floods. As overlying sediment is transported downstream, the vertical...

Christopher F. Waythomas
2021, Frontiers in Earth Science (9)
This study addresses the characteristics, potential hazards, and both eruptive and non-eruptive role of water at selected volcanic crater lakes in Alaska. Crater lakes are an important feature of some stratovolcanoes in Alaska. Of the volcanoes in the state with known Holocene eruptive activity, about one third have summit crater...

2021, NOAA Technical Memorandum NMFS-SWFSC 657
Deep-sea coral and sponge (DSCS) communities serve as essential fish habitats (EFH) by providing shelter and nursery habitat, increasing diversity, and increasing prey availability (Freese and Wing, 2003; Bright, 2007; Baillon et al., 2012; Henderson et al., 2020). Threats to these long-lived, fragile organisms from bottom contact fishing gear, potential...
