Gilberto Binda, Andrea Pozzi, Alessandro Michetti, Paula Noble, Michael R. Rosen
2020, Minerals (10)
Earthquakes are known to affect groundwater properties, yet the mechanisms causing chemical and physical aquifer changes are still unclear. The Apennines mountain belt in Italy presents a rich literature of case studies documenting hydrogeochemical response to seismicity, due to the high frequency of seismic events and the presence of different...

>In the current era of rapid climate change, accurate characterization of climate-relevant gas dynamics – namely production, consumption, and net emissions – is required for all biomes, especially those ecosystems most susceptible to the impact of change. Marine environments include regions that act as net sources or sinks for numerous...
Use of real-time sensors to temporally characterize water quality in groundwater and surface water in Mason County, Illinois, 2017–19
Lance R. Gruhn, William S. Morrow
2020, Scientific Investigations Report 2020-5108
The persistence of high nitrate concentrations in shallow groundwater has been well documented in the shallow glacial aquifer of Mason County, Illinois. Nitrates in groundwater can be a concern when concentrations exceed 10 milligrams per liter in drinking water. Additionally, nitrate in groundwater can contribute to surface water nitrogen loads...
Sphalerite oxidation in seawater with covellite: Implications for seafloor massive sulfide deposits and mine waste
Amy Gartman, Samantha P. Whisman, James R. Hein
2020, ACS Earth and Space Chemistry (4) 2261-2269
Metal sulfide minerals exist in several marine environments and are in thermodynamic disequilibrium with oxygenated seawater from the time of their formation. Oxidation is both ubiquitous and heterogeneous, as observational and experimental evidence demonstrates that sulfide minerals may oxidize completely on decadal...

Erik S Jules, Phillip J. van Mantgem, Benjamin G Iberle, Jonathan C B Nesmith, Regina M Rochefort
2020, Northwest Science (94) 129-141
Whitebark pine (Pinus albicaulis) is a long-lived tree found in high-elevation forests of western North America that is declining due to the non-native white pine blister rust (Cronartium ribicola) and climate-driven outbreaks of mountain pine beetle (Dendroctonus ponderosae; MPB). The National Park Service established a...

2020, Applied Geochemistry
Thirty water wells were sampled in 2018 to understand the geochemistry and age of groundwater in the Williston Basin and assess potential effects of shale-oil production from the Three Forks-Bakken petroleum system (TBPS) on groundwater quality. Two geochemical groups are identified...
Challenging our understanding of western Yellow-billed Cuckoo habitat needs and accepted management practices
P.J. Wohner, S.A. Laymon, J.E. Stanek, Sammy L. King, R.J. Cooper
2020, Restoration Ecology (29)
Riparian restoration in the southwestern United States frequently involves planting cottonwood (Populus spp.) and willow (Salix spp.). In the absence of flooding and gap-forming disturbance, planted forests often senesce without further young tree recruitment. This has largely been the case in California riparian systems that historically supported state-endangered western Yellow-billed Cuckoo (Coccyzus...

David A. Eads, Dean E. Biggins, Kenneth L. Gage
2020, Vector-Borne and Zoonotic Diseases (20) 888-896
Plague originated in Asia as a flea-borne zoonosis of mammalian hosts. Today, the disease is distributed nearly worldwide. In western United States of America, plague is maintained, transmitted, and amplified in diverse communities of rodents and fleas. We examined flea diversity on three species of prairie dogs (Cynomys spp., PDs) and...

Deep-sea coral and sponge taxa increase demersal fish diversity and the probability of fish presence
Mark J. Henderson, D.D. Huff, M.M Yoklavich
2020, Frontiers in Marine Science (7)
Fishes are known to use deep-sea coral and sponge (DSCS) species as habitat, but it is uncertain whether this relationship is facultative (circumstantial and not restricted to a particular function) or obligate (necessary to sustain fish populations). To explore whether DSCS provide essential habitats for demersal fishes, we analyzed 10...

Clinton B. Leach, Jennifer A. Hoeting, Kim M. Pepin, Alvaro E. Eiras, Mevin Hooten, Colleen T. Colleen T. Webb
2020, PLoS Neglected Tropical Diseases (14) 1-20
Our ability to effectively prevent the transmission of the dengue virus through targeted control of its vector, Aedes aegypti, depends critically on our understanding of the link between mosquito abundance and human disease risk. Mosquito and clinical surveillance data are widely collected, but linking them requires a modeling framework that accounts...

Elizabeth P Flesch, Tabitha A. Graves, Jennifer Thomson, Kelly Proffitt, P.J. White, Thomas R Stephenson, Robert A. Garrott
2020, Ecology and Evolution (10) 13687-13704
Wildlife restoration often involves translocation efforts to reintroduce species and supplement small, fragmented populations. We examined the genomic consequences of bighorn sheep (Ovis canadensis) translocations and population isolation to enhance understanding of evolutionary processes that affect population genetics and inform future restoration strategies. We conducted a population genomic analysis of...
Perceived ecological threats and economic benefits of non-native black bass in the United States
Lauren Seguy, James M. Long
2020, Fisheries Magazine (46) 56-65
Black bass Micropterus spp. are highly sought-after sport fish and, where introduced, are emblematic of the tradeoffs between ensuring productive fisheries and conserving native biodiversity. To disentangle these potentially conflicting interests, we administered a survey of fisheries biologists in the United States to assess perceptions regarding ecological and economic impacts of non-native...
