2020, Transactions of the American Fisheries Society (149) 681-694
Delineation of management units across broad spatial scales can help to visualize population structuring and identify conservation opportunities. Geographical information system (GIS) approaches can be useful for developing broad‐scale management units, especially when paired with field data that can validate the GIS‐based delineations. Genetic data can be useful for evaluating...

David M. Rubin, Daniel D. Buscombe, Scott Wright, David J. Topping, Paul E. Grams, John C. Schmidt, J.E. Hazel Jr., Matthew A. Kaplinski, Robert B. Tusso
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...

2020, Frontiers in Microbiology (11)
Permafrost is an extreme habitat yet it hosts microbial populations that remain active over millennia. Using permafrost collected from a Pleistocene chronosequence (19 to 33 ka), we hypothesized that the functional genetic potential of microbial communities in permafrost would reflect microbial strategies to metabolize permafrost soluble organic matter (OM) in situ over...
