Steve Bennett and Nick Bouwes just published a pair of important pair of papers in Fisheries this month highlighting the groups work on Intensively Monitored Watersheds (including Bridge Creek beaver restoration and Asotin Creek HDLWD restoration) and Adaptive Management in the Asotin Creek IMW. There has been a fair amount of positive press surrounding their publication including an Associated Press article and this USU Today piece.

Sara Bangen and team just had a paper in Water Resources Research accepted that lays out how fuzzy inference systems are used in the Columbia Habitat Monitoring Program to model DEM errors. We hope the paper will provide guidance for those looking to use fuzzy inference systems for DEM error modelling and show the advantages of adding more inputs into such models.

The capacity model from the Beaver Restoration Assessment Tool (BRAT) was finally published as part of an invited contribution for a special issue in Geomorphology associated with the 2016 Bingahmton Geomorphology Symposium. A full copy of the text can be viewed on Researcher Gate.
This paper lays out the rationale for the capacity model and presents results from the Utah BRAT run as context.

The ET-AL's Alan Kasprak, Becca Rossi, Nick Bouwes, Joe Wheaton and the USFS's Brett Roper and I (Nate Hough-Snee) recently had our paper on models of instream wood in the interior Columbia River Basin, "Hydrogeomorphic and Biotic Drivers of Instream Wood Differ Across Sub-basins of the Columbia River Basin, USA," published in River Research Applications. This paper explores how climate and hydrologic and ecological settings differ between CHaMP sub-basins and how these settings correspond to different wood loads.

The ET-AL continues their collaborations with geographers/geomorphologists down under, Kirstie Fryirs (Macquarie), and Gary Brierley (Auckland), as the much anticipated, "Geomorphic mapping and taxonomy of fluvial landforms" has been accepted and is now in press at Geomorphology. This paper, which presents a classification and taxonomy of fluvial landforms, clarifies the terminology used to describe landforms in and around rivers, and their evolution. The paper features numerous ET-Al/FHC personnel, including Sara Bangen, Gary O' Brien, and Nick "the Bouwes" Bouwes. Check it out at Geomorphology: http://dx.doi.org/10.1016/j.geomorph.2015.07.010

Nearly three years ago I presented the results from this my undergraduate study examining aggression between Tiger, Rainbow, and Cutthroat trout at the Western AFS meeting in Boise, ID. Finally, with a lot of help from my advisor, Phaedra Budy, and numerous other folks in the Watershed Sciences Department we were able to get the article published in North American Journal of Fisheries Management.

Phaedra Budy, Mary Conner, and Nira Salant recently completed an effort in collaboration with the FHC's Wally MacFarlane to quantify the occupancy, extinction, and colonization of the endangered and threatened "big three" fish species at locations within the Colorado River Basin, USA. This contribution examines how hydrologic and landscape variability influence populations of bluehead sucker, roundtail chub, and flannelmouth sucker across space and time. The effort was published in Conservation Biology and is in press now.
Congratulations to Phaedra, Mary, Nira and Wally on their contribution to the understanding and conservation of these desert fishes.

Stephen Bennett published the results of seven years of spawning surveys for Bonneville Cutthroat Trout in a Logan River tributary as part of his post-doctoral research with Brett Roper of the USFS. Little is known about the variability in the spatial and temporal distribution of spawning potamodromous trout despite decades of research directed at salmonid spawning ecology and the increased awareness that conserving life history diversity should be a focus of management. We monitored a population of fluvial–resident Bonneville Cutthroat Trout Oncorhynchus clarkii utah in a tributary to the Logan River, Utah, from 2006 to 2012 to gain insight into the distribution and timing of spawning and what factors may influence these spawning activities.We monitored Bonneville Cutthroat Trout using redd surveys with multiple observers and georeferenced redd locations.We documented an extended spawning period that lasted from late April tomid-July. The onset,median, and end of spawning was best predicted by the mean maximum water temperature during the first 13 weeks of the year (F=130. 4, df=5, R2=0.96, P<0.0001) with spawning beginning and ending earlier in years that had warmer water temperatures prior to spawning. The distribution of redds was clumped each year and the relative density of redds was greater in a reach dominated by dams constructed by beavers Castor canadensis. Both dam failure and construction appeared to be responsible for creating new spawning habitat that was quickly occupied, demonstrating rapid temporal response to local habitat changes. Bonneville Cutthroat Trout appeared to establish and defend a redd for up to 2 d, and spawning most often occurred between similar-sized individuals. Spawning surveys for potamodromous trout are an underutilized tool that could be used to better understand the distribution and timing of spawning as well as determine the size and trends of the reproducing portion of populations of management concern. Without efforts to document the diversity of this important aspect of potamodromous trout life history, prioritization of conservation will be problematic.

Alan Kasprak recently published a portion of his dissertation, "The relationship between particle travel distance and channel morphology: Results from physical models of braided rivers" in the Journal of Geophysical Research: Earth Surface. This output was a part of Alan's flume work on understanding particle transport and settlement in braided river systems. It was undertaken in the summer of 2013, and completed at the University of Western Ontario in mountainous London, Ontario, Canada. Co-authors include Peter Ashmore, Sarah Peirce, Joe Wheaton and James Hensleigh.

One of my master's projects detailing the differences between Carex life history strategies was recently published as the lead-off in the January issue of Aquatic Botany. This paper compared two common wetland indicator species, Carex obnupta, an evergreen, hydrophytic sedge, and Carex stipata, a deciduous, hydrophytic sedge, to see how fertilization and flooding shaped each species' growth and biomass allocation. This paper has implications for explaining both species' life history strategies, and also for selecting and installing both species in created or restored wetlands.
I published this with, former UW SEFS grad student and current UC Davis postdoctoral fellow, Lloyd Nackley, and two of my committee members at UW, Drs. Kern Ewing and Soo-Hyung Kim
