Spatial distribution of water level impact to back-barrier bays
Alfredo Aretxabaleta, Neil K. Ganju, Zafer Defne, Richard P. Signell
2019, Natural Hazards and Earth System Sciences (19) 1823-1838
Water level in semi-enclosed bays, landward of barrier islands, is mainly driven by offshore sea level fluctuations that are modulated by bay geometry and bathymetry, causing spatial variability in the ensuing response (transfer). Local wind setup can have a secondary role that depends on wind speed, fetch, and relative orientation...

Nathan V. Banet, David A. Hewitt
2019, Open-File Report 2019-1085
Data from a 4-year capture and transport program were used to assess translocation as a management strategy for two long-lived, federally endangered catostomids in the Upper Klamath Basin, Oregon. Lost River (Deltistes luxatus) and shortnose (Chasmistes brevirostris) suckers, two species endemic to the Klamath Basin, were translocated from Lake...

Carrie J. Blakeslee, William A. Lellis
2019, Journal of Shellfish Research (38) 379-384
The eastern elliptio Elliptio complanata is a species of freshwater mussel common to streams and rivers of the Atlantic Coast. Egg fertilization, larval brooding, and glochidial release are reported to occur within a period of several weeks during early to midsummer. In this study, mussels were exposed to manipulated photoperiod and water...
New insights into the ecology of adfluvial Bull Trout and the population response to the Endangered Species Act in the North Fork Lewis River, Washington
Robert K. Al-Chokhachy, Jeremiah Doyle, James Lampierth
2019, Transactions of the American Fisheries Society (148) 1102-1116
Like many other salmonids, Bull Trout Salvelinus confluentus migratory life-history expressions are becoming increasingly rare. A critical step in effectively refining management and conservation strategies is a robust assessment of the effectiveness of such strategies and key biological information used in monitoring and recovery planning. To address this...
Evaluating the temperature difference parameter in the SSEBop model with satellite observed land surface temperature data
Lei Ji, Gabriel B. Senay, Naga Manohar Velpuri, Stefanie Kagone
2019, Remote Sensing (11)
The Operational Simplified Surface Energy Balance (SSEBop) model uses the principle of satellite psychrometry to produce spatially explicit actual evapotranspiration (ETa) with remotely sensed and weather data. The temperature difference (dT) in the model is a predefined parameter quantifying the difference between surface temperature at bare soil and air...

Measurement method has a larger impact than spatial scale for plot-scale field-saturated hydraulic conductivity (Kfs) after wildfire and prescribed fire in forests
Brian A. Ebel
2019, Earth Surface Processes and Landforms (44) 1945-1956
Abstract Wildfires raise risks of floods, debris flows, major geomorphologic and sedimentologic change, and water quality and quantity shifts. A principal control on the magnitude of these changes is field-saturated hydraulic conductivity (Kfs), which dictates surface runoff generation and is a key input into numerical models. This work synthesizes 73...
Variable hybridization outcomes in trout are predicted by historical fish stocking and environmental context
Elizabeth G. Mandeville, Annika W. Walters, Brittany J. Nordberg, Karly H. Higgins, Jason C. Burckhardt, Catherine E. Wagner
2019, Molecular Ecology (28) 3738-3755
Hybridization can profoundly affect the genomic composition and phenotypes of closely related species, and provides an opportunity to identify mechanisms that maintain reproductive isolation between species. Recent evidence suggests that hybridization outcomes within a species pair can vary across locations. However, we still don’t know how extensive variation in outcomes...

Elevated heterozygosity in adults relative to juveniles provides evidence of viability selection on eagles and falcons
Jacqueline M. Doyle, Janna R Willoughby, Douglas A. Bell, Peter H. Bloom, Evgeny A. Bragin, Nadia B. Fernandez, Todd E. Katzner, Kolbe Leonard, J Andrew DeWoody
2019, Journal of Heredity (110) 696-706
Viability selection yields adult populations that are more genetically variable than those of juveniles, producing a positive correlation between heterozygosity and survival. Viability selection could be the result of decreased heterozygosity across many loci in inbred individuals and a subsequent decrease in survivorship resulting from the expression of the deleterious...
Predicting persistence of Rio Grande Cutthroat Trout populations in an uncertain future
Mathew P. Zeigler, Kevin B. Rogers, James Roberts, Andrew Todd, Kurt D. Fausch
2019, North American Journal of Fisheries Management (39) 819-848
The Rio Grande Cutthroat Trout Oncorhynchus clarkii virginalis (RGCT ) occupies just 12% of its ancestral range. As the southernmost subspecies of Cutthroat Trout, we expect a warming climate to bring additional stressors to RGCT populations, such as increased stream temperatures, reduced streamflows, and increased incidence of wildfire. We developed a Bayesian...

Spatial memory shapes migration and its benefits: Evidence from a large herbivore
Jerod A. Merkle, Hall Sawyer, Kevin L. Monteith, Samantha P. Dwinnell, Gary L. Fralick, Matthew J. Kauffman
2019, Ecology Letters (22) 1797-1805
From fine-scale foraging to broad-scale migration, animal movement is shaped by the distribution of resources. There is mounting evidence, however, that learning and memory also guide movement. Although migratory mammals commonly track resource waves, how resource tracking and memory guide long-distance migration has not been reconciled....
Citing aquatic monitoring data sets: Best practice recommendations for authoritative data citation
Sheryn J. Olson, Katie A Barnas, Margaret Williams, Christopher Wheaton, Michael Banach, Jennifer M. Bayer
2019, Report
The use of data generated from long term monitoring efforts necessitates accurate authoritative source citations of those data to ensure credit for data collected, and accountability for the data quality to enable repeated retrieval of a given data set. Data sets used in published reports and articles are increasingly being...

2019, Earth and Planetary Science Letters (524) 1-14
The 9 month long 2011-2012 eruption of Cordon Caulle (Southern Andes, Chile) is the best instrumentally recorded rhyolitic eruption to date and the first time that the effusion of a rhyolitic flow has been observed in detail. We use Interferometric Synthetic Aperture Radar (InSAR), with time-lapse DEMs and numerical models...
Global positioning system tracking devices can decrease Greater Sage-Grouse survival
John P. Severson, Peter S. Coates, Brian G. Prochazka, Mark A. Ricca, Michael L. Casazza, David J Delahunty
2019, The Condor (121)
Reliable demographic estimates hinge on the assumption that marking animals does not alter their behavior, reproduction, or survival. Violations can bias inference and are especially egregious for species of high conservation concern. Global positioning system (GPS) devices represent a recent technological advancement that has contributed greatly to avian ecological studies...

2019, Science of the Total Environment (695)
Worldwide, eutrophication is threatening lake ecosystems. To support lake management numerous eutrophication models have been developed. Diverse research questions in a wide range of lake ecosystems are addressed by these models. The established models are based on three key approaches: the empirical approach that employs field surveys, the theoretical approach...
