Allen C. Gellis, Faith A. Fitzpatrick, Joseph Schubauer-Berigan
2016, Report
Sediment is an important pollutant of concern that can degrade and alter aquatic habitat. A sediment budget is an accounting of the sources, storage, and export of sediment over a defined spatial and temporal scale. This manual focuses on field approaches to estimate a sediment budget. We also highlight the...
Nature vs. nurture: Evidence for social learning of conflict behaviour in grizzly bears
Andrea T. Morehouse, Tabitha A. Graves, Nathaniel Mikle, Mark S. Boyce
2016, PLoS ONE (11)
The propensity for a grizzly bear to develop conflict behaviours might be a result of social learning between mothers and cubs, genetic inheritance, or both learning and inheritance. Using non-invasive genetic sampling, we collected grizzly bear hair samples during 2011–2014 across southwestern Alberta, Canada. We targeted private agricultural lands for...

Clint C. Muhlfeld, Vincent S. D'Angelo, Christopher C. Downs, John D. Powell, Stephen J. Amish, Gordon Luikart, Ryan Kovach, Matthew Boyer, Steven T. Kalinowski
2016, Transactions of the American Fisheries Society (145) 1093-1109
Invasive hybridization is one of the greatest threats to the persistence of Westslope Cutthroat Trout Oncorhynchus clarkii lewisi. Large protected areas, where nonhybridized populations are interconnected and express historical life history and genetic diversity, provide some of the last ecological and evolutionary strongholds for conserving this species. Here, we describe the genetic status...

Streamflow ratings
Robert R. Holmes Jr.
Vijay P. Singh, editor(s)
2016, Book chapter, Handbook of Applied Hydrology
Autonomous direct determination of a continuous time series of streamflow is not economically feasible at present (2014). As such, surrogates are used to derive a continuous time series of streamflow. The derivation process entails developing a streamflow rating, which can range from a simple, single-valued relation between stage and streamflow to a fully dynamic...
