2020, Journal of Geophysical Research, Earth Surface (125)
Rivers commonly exhibit substantial variability in suspended‐sand concentration, even at constant water discharge. Here we derive an approach for evaluating how much of this variability arises from mean bed‐sand grain size. We apply this approach to the Colorado River in Grand Canyon, where discharge‐independent concentration of suspended sand varies by...
Nutrient removal and uptake by native planktonic and biofilm bacterial communities in an anaerobic aquifer
John T. Lisle
2020, Frontiers in Microbiology (11)
Managed aquifer recharge (MAR) offers a collection of water storage and storage options that have been used by resource managers to mitigate the reduced availability of fresh water. One of these technologies is aquifer storage and recovery (ASR), where surface water is treated then recharged into a storage zone within...

2020, Northeastern Naturalist (27) N40-N47
Little is known about hypogeous, sequestrate (i.e., truffles) fungi in the eastern United States. Since the fruiting bodies of these fungi are part of the diet of multiple rodent species, filling data gaps is important to understanding more about truffle species distribution and habitat associations. During a microhabitat study on...
Managing state lands for wildlife
Thomas Ryder, John F. Organ
2020, Book chapter, The wildlife techniques manual.
State-owned lands are a vital component of state fish and wildlife management programs because they contain valuable habitats for a diversity of wild species and often provide important public access. The Association of Fish and Wildlife Agencies (AFWA 2017) reported state agencies manage or administer approximately 188 million hectares of...

M.J. Stock, D. Geist, DA Neave, M.L.M . Gleason, B. Bernard, Keith A. Howard, I. Buisman, J. Maclennan
2020, Nature Communications (11)
Many volcanoes erupt compositionally homogeneous magmas over timescales ranging from decades to millennia. This monotonous activity is thought to reflect a high degree of chemical homogeneity in their magmatic systems, leading to predictable eruptive behaviour. We combine petrological analyses of erupted crystals with new thermodynamic models...
