Matthew G. Mesa, Lisa P. Gee, Lisa K. Weiland, Helena E. Christiansen
2013, North American Journal of Fisheries Management (33) 1179-1183
We assessed the physiological stress responses (i.e., plasma levels of cortisol, glucose, and lactate) of adult Rainbow Trout Oncorhynchus mykiss at selected time intervals after they had passed a distance of 15 m through a unique fish conveyance device (treatment fish) or not (controls). This device differs from traditional fish...
Spatio-temporal variability in movement, age, and growth of mountain whitefish (Prosopium williamsoni) in a river network based upon PIT tagging and otolith chemistry
Joseph R. Benjamin, Lisa A. Wetzel, Kyle D. Martens, Kimberly Larsen, Patrick J. Connolly
2013, Canadian Journal of Fisheries and Aquatic Sciences (70) 1-10
Connectivity of river networks and the movements among habitats can be critical for the life history of many fish species, and understanding of the patterns of movement is central to managing populations, communities, and the landscapes they use. We combined passive integrated transponder tagging over 4 years and strontium isotopes...

Peter Ruggerio, Meredith G. Kratzmann, Emily A. Himmelstoss, David Reid, Jonathan Allan, George Kaminsky
2013, Open-File Report 2012-1007
Beach erosion is a chronic problem along most open ocean shores of the United States. As coastal populations continue to increase and infrastructure is threatened by erosion, there is increased demand for accurate information regarding past and present trends and rates of shoreline movement. There is also a need for...

Tammy D. Hoem Neher, Amanda E. Rosenberger, Christian E. Zimmerman, Coowe M. Walker, Steven J. Baird
2013, Transactions of the American Fisheries Society (142) 1481-1494
For Pacific salmon, estuaries are typically considered transitional staging areas between freshwater and marine environments, but their potential as rearing habitat has only recently been recognized. The objectives of this study were two-fold: (1) to determine if Coho Salmon Oncorhynchus kisutch were rearing in estuarine habitats, and (2) to characterize...

Jeremy D. Decker, J.D. Hughes
2013, Book, MODFLOW and More 2013: Translating Science into Practice: Conference Proceedings
Climate change and sea-level rise could cause substantial changes in urban runoff and flooding in low-lying coast landscapes. A major challenge for local government officials and decision makers is to translate the potential global effects of climate change into actionable and cost-effective adaptation and mitigation strategies at county and municipal...
Silicate melt inclusion evidence for extreme pre-eruptive enrichment and post-eruptive depletion of lithium in silicic volcanic rocks of the western United States: implications for the origin of lithium-rich brines
Albert H. Hofstra, T.I. Todorov, C.N. Mercer, D.T. Adams, E.E. Marsh
2013, Economic Geology (108) 1691-1701
To evaluate whether anatectic and/or highly fractionated lithophile element-enriched rhyolite tuffs deposited in arid lacustrine basins lose enough lithium during eruption, lithification, and weathering to generate significant Li brine resources, pre-eruptive melt compositions, preserved in inclusions, and the magnitude of post-eruptive Li depletions, evident in host rhyolites, were documented at...
Inferring tidal wetland stability from channel sediment fluxes: observations and a conceptual model
Neil K. Ganju, Nicholas J. Nidzieko, Matthew L. Kirwan
2013, Journal of Geophysical Research F: Earth Surface (118) 2045-2058
Anthropogenic and climatic forces have modified the geomorphology of tidal wetlands over a range of timescales. Changes in land use, sediment supply, river flow, storminess, and sea level alter the layout of tidal channels, intertidal flats, and marsh plains; these elements define wetland complexes. Diagnostically, measurements of net sediment fluxes...
Controls on ecosystem and root respiration across a permafrost and wetland gradient in interior Alaska
Nicole A. McConnell, Merritt R. Turetsky, A. David McGuire, Evan S. Kane, Mark P. Waldrop, Jennifer W. Harden
2013, Environmental Research Letters (8)
Permafrost is common to many northern wetlands given the insulation of thick organic soil layers, although soil saturation in wetlands can lead to warmer soils and increased thaw depth. We analyzed five years of soil CO2 fluxes along a wetland gradient that varied in permafrost and soil moisture conditions. We...

Daniel Tush, Keith A. Loftin, Michael T. Meyer
2013, Journal of Chromatography A (1319) 80-87
Little is known about the occurrence, fate, and effects of the ancillary additives in pesticide formulations. Polyoxyethylene tallow amine (POEA) is a non-ionic surfactant used in many glyphosate formulations, a widely applied herbicide both in agricultural and urban environments. POEA has not been previously well characterized, but has been shown...
