Audrey Baetz, Taaja Tucker, Robin DeBruyne, Alex Gatch, T. Hook, J. Fischer, Edward F. Roseman
2020, Water (12)
Rocky reefs provide important spawning and refuge habitats for lithophilic spawning fishes. However, many reefs have been lost or severely degraded through anthropogenic effects like dredging, channelization, or sedimentation. Constructed reefs have been used to mitigate these effects in some systems, but these reefs are also subject to degradation which...
Effects of water level alteration on carbon cycling in peatlands
Yehui Zhong, Jiang Ming, Beth Middleton
2020, Ecosystem Health and Sustainability (6)
Globally, peatlands play an important role in the carbon (C) cycle. High water level is a key factor in maintaining C storage in peatlands, but water levels are vulnerable to climate change and anthropogenic disturbance. This review examines literature related to the effects of water level alteration on C cycling...

Newly developed, high‐resolution flow models and aquatic species databases provide enormous opportunity, but the volume of data can prove challenging to manage without automated tools. The objective of this study was to develop a...
Concealment of juvenile bull trout in response to temperature, light, and substrate: Implications for detection
Russell F. Thurow, James T. Peterson, Gwynne L. Chandler, Christine M. Moffitt, Theodore C. Bjornn
2020, PLoS ONE (15)
Bull trout (Salvelinus confluentus) are challenging to detect as a result of the species cryptic behavior and coloration, relatively low densities in complex habitats, and affinity for cold, high clarity, low conductivity waters. Bull trout are also closely associated with the stream bed, frequently conceal in substrate, and this concealment behavior...

Julie Kinzelman, Muruleedhara Byappanahalli, Meredith B. Nevers, Dawn Shively, Stephan Kurdas, Cindy H Nakatsu
2020, Journal of Microbiological Methods (178)
Hydro-meteorological conditions facilitate transport of fecal indicator bacteria (FIB) to the nearshore environment, affecting recreational water quality. North Beach (Racine, Wisconsin, United States), is an exemplar public beach site along Lake Michigan, where precipitation-mediated surface runoff, wave encroachment, stormwater and tributary outflow were demonstrated to contribute to beach advisories. Multiple...

Michelle Sneed, Justin T. Brandt
2020, Scientific Investigations Report 2020-5093
Groundwater has been a major source of agricultural, recreational, municipal, and domestic supply in the Coachella Valley of California since the early 1920s. Pumping of groundwater resulted in groundwater-level declines as large as 50 feet (ft) or 15 meters (m) by the late 1940s. Because of concerns that the...
Science to support water-resource management in the upper Roanoke River watershed
James S. Webber, John D. Jastram
2020, Fact Sheet 2020-3040
Flooding, excessive sedimentation, and high bacteria counts are among the most challenging water resource issues affecting the Upper Roanoke River watershed. These issues threaten public safety, impair the watershed’s living resources, and threaten drinking water supplies, though mitigation is costly and difficult to manage.Urban development, land disturbance, and changing climatic...

Stanley Grant, Ahmed Monofy, Fulvio Boano, Jesus Gomez-Velez, Ian Guymer, Judson Harvey, Marco Ghisalberti
2020, Water Resources Research (56)
Many water quality and ecosystem functions performed by streams occur in the benthic biolayer, the biologically active upper (~5 cm) layer of the streambed. Solute transport through the benthic biolayer is facilitated by bedform pumping, a physical process in which dynamic and static pressure variations over the surface of stationary bedforms...
