Richard A. Erickson
2019, Book chapter, 2019 Asian carp interim summary report
The Spatially Explicit Asian carp Population (SEAcarP) model was developed to inform management and research decisions with the goal of minimizing the abundance of Bighead Carp and Silver Carp (collectively referred to as “Asian carp” in this document) in the upper Illinois River waterway, thereby reducing risk of population expansion...
Diel feeding and movement activity of Northern Snakehead Channa argus
Nicolas W. R. Lapointe, Ryan K. Saylor, Paul L. Angermeier
2019, Conference Paper, American Fisheries Society symposium 89
Understanding the diel activity of a species can shed light on potential interactions with other species and inform management practices. To understand the diel activity of Northern Snakehead Channa argus, feeding habits and movement patterns were observed. Two hundred seventy-three Northern Snakehead were captured by boat electrofishing during May and June...

Annie Rossi, Robert Graham, Katherine J. Kendrick
2019, Catena (183)
Soil chronosequences on alpine moraine complexes have been used to help unravel the glacial histories of the eastern Sierra Nevada. The moraine sequence along Bishop Creek includes well-preserved moraines that have been previously dated using cosmogenic 36Cl surface exposure ages. The goal of this study was to interpret pedogenesis within a...

National assessment of shoreline change — Historical shoreline change along the north coast of Alaska, Icy Cape to Cape Prince of Wales
Ann E. Gibbs, Alexander G. Snyder, Bruce M. Richmond
2019, Open-File Report 2019-1146
Beach erosion is a persistent problem along most open-ocean shores of the United States. Along the Arctic coast of Alaska, coastal erosion is widespread and threatens communities, defense and energy-related infrastructure, and coastal habitat. As coastal populations continue to expand and infrastructure and habitat are increasingly threatened by erosion, there...

Ken Eng, Daren M. Carlisle, Theodore E. Grantham, David M. Wolock, Rosaly L. Eng
2019, Scientific Investigations Report 2019-5001
Alteration of the natural streamflow regime by land and water management, such as land-cover change and dams, is associated with aquatic ecosystem degradation. The severity and geographic extent of streamflow alteration at regional and national scales, however, remain largely unquantified. The primary goal of this study is to characterize the...

2019, Scientific Investigations Map 3445
Beaver Lake was constructed in 1966 on the White River in the northwest corner of Arkansas for flood control, hydroelectric power, public water supply, and recreation. The surface area of Beaver Lake is about 27,900 acres and approximately 449 miles of shoreline are at the conservation pool level (1,120 feet...
Temporal variations in scrubbing of magmatic gases at the summit of Kīlauea Volcano, Hawai‘i
Shaul Hurwitz, Kyle R. Anderson
2019, Geophysical Research Letters (46) 14469-14476
Measurements of gas compositions and emission rates play a major role in monitoring restless volcanoes. However, thermodynamic calculations imply that scrubbing by groundwater will prevent most HCl and significant SO2 emissions until dry pathways are established, thus leading to underestimates of gas released from magma and magma volumes. Despite the...

A hydrogeomorphic classification of connectivity of large rivers of the Upper Midwest, United States
Robert B. Jacobson, Jason J. Rohweder, Nathan R. De Jager
2019, Scientific Investigations Report 2019-5132
River connectivity is defined as the water-mediated exchange of matter, energy, and biota between different elements of the riverine landscape. Connectivity is an especially important concept in large-river corridors (channel plus floodplain ) because large rivers integrate fluxes of water, sediment, nutrients, contaminants, and other transported constituents emanating from large...

Ciaran Alvar Seeland Shaughnessy, Stephen D. McCormick
2019, American Journal of Physiology - Regulatory, Integrative and Comparative Physiology (318) R17-R29
The present study provides molecular and functional characterization of Na+/K+/2Cl- cotransporter (nkcc1/NKCC1) in the gills of sea lamprey, the most basal extant vertebrate with an osmoregulatory strategy. We report the full-length peptide sequence for the lamprey NKCC1, which we show to group strongly with and occupy a basal position among...
Aridity drives spatiotemporal patterns of masting across the latitudinal range of a dryland conifer
Andreas Wion, Peter Weisberg, Ian S. Pearse, Miranda D. Redmond
2019, Ecography (43) 569-580
Masting, or the synchronous and irregular production of seed crops, is controlled by environmental conditions and resource budgets. Increasing temperatures and shifting precipitation regimes may alter the frequency and magnitude of masting, especially in species that experience chronic resource stress. Yet the effects of a changing...
Factors influencing neonicotinoid insecticide concentrations in floodplain wetland sediments across Missouri
K.J. Kuechle, Elisabeth B. Webb, D. Mengel, A.R. Main
2019, Environmental Science and Technology (53) 10591-10600
Widespread use of neonicotinoid insecticides in North America has led to frequent detection of neonicotinoids in surface waters. Despite frequent surface water detection, few studies have evaluated underlying sediments for the presence of neonicotinoids. Thus, we sampled water and sediments for...

James A. Luoma, Diane L. Waller, Todd J. Severson, Matthew Barbour, Jeremy K. Wise, Eric G. Lord, Lynn A. Bartsch, Michelle R. Bartsch
2019, Open-File Report 2019-1126
Zebra mussels (Dreissena polymorpha) are invasive bivalves that have perturbed aquatic ecosystems within North America since their introduction in the mid-1980s. Control of zebra mussels has largely been restricted to raw water conveyance systems and associated infrastructures because few control products are registered for application in surface waters. The biopesticide...
