Abstract (From http://journals.ametsoc.org/doi/abs/10.1175/JHM-D-15-0062.1): Over mountainous terrain, ground weather radars face limitations in monitoring surface precipitation as they are affected by radar beam blockages along with the range-dependent biases due to beam broadening and increase in altitude with range. These issues are compounded by precipitation structures that are relatively shallow and experience growth at low levels due to orographic enhancement. To improve surface precipitation estimation, researchers at the University of Oklahoma have demonstrated the benefits of integrating the Tropical Rainfall Measuring Mission (TRMM) Precipitation Radar (PR) products into the ground-based NEXRAD rainfall...
Abstract (from Taylor & Francis Online): Climate change is altering glacial lake fisheries in the United States, presenting a complex challenge for fisheries managers. Here we provide a regional perspective to guide management of heterogeneous and yet interdependent fishery resources in glacial lakes of the upper Midwest. Our main objective was to promote the adaptation of inland glacial lakes fisheries management to climate change by outlining processes that support regional plans. Using examples from the glacial lakes region, we outline an approach for regional prioritization, specify strategies for moving from regional prioritization to on-the-ground action, and provide guidance on the implementation of management...

Daily streamflow and reservoir water elevation data for modeled locations in the Red River Basin. Values reported are for 18 different GCM (Global Climate Model) / RCP (Representative Concentration Pathway) / GDM Downscaling scenarios. Climate data from each scenario was input into a Variable Infiltration Capacity (VIC) model, that output flow values. These values were then input into RiverWare, to determine the impacts on regulated flows, lake levels and water availability. RiverWare was used for this project, because of its ability to simulate water use, reservoir operations, and local/interstate regulations.
The Fourth Annual Pacific Northwest Climate Science Conference was held in Portland, Oregon on September 5-6, 2013. The Conference is an annual forum for researchers and practitioners to convene and exchange scientific results, challenges, and solutions related to the effects of climate on people, natural resources, and infrastructure in the Pacific Northwest. The Conference attracts a wide range of participants including policy- and decision-makers, resource managers, public agency staff, non-governmental organization personnel, and scientists. As such, the Conference emphasizes oral presentations that are comprehensible to a wide audience and on topics of broad interest and aims to be the best opportunity to stimulate...

Abstract (from http://ascelibrary.org/doi/abs/10.1061/(ASCE)HE.1943-5584.0001282): A novel multisite cascading calibration (MSCC) approach using the shuffled complex evolution–University of Arizona (SCE-UA) optimization method, developed at the University of Arizona, was employed to calibrate the variable infiltration capacity (VIC) model in the Red River Basin. Model simulations were conducted at 35 nested gauging stations. Compared with simulated results using a priori parameters, single-site calibration can improve VIC model performance at specific calibration sites; however, improvement is still limited in upstream locations. The newly developed MSCC approach overcomes this limitation. Simulations using MSCC...
This short-term project responded to concerns about the disappearance of culturally important plants in traditional gathering areas expressed by elders of the Port Gamble S’Klallam Tribe (PGST) (Olympic Peninsula, WA), both currently and in response to continuing climate change. A formal Memorandum of Understanding was developed between Oregon State University and the PGST to guide this culturally sensitive research. We recommend this formal approach to researchers considering tribal partnerships in order to ensure expectations of all parties are clearly outlined. During formal interviews and informal conversation, PGST elders mentioned 37 plants, of which eight terrestrial species and a group of marine taxa were...
Abstract (from http://link.springer.com/article/10.1007%2Fs10584-013-0852-y): This paper provides an overview of climate change impacts on tribal water resources and the subsequent cascading effects on the livelihoods and cultures of American Indians and Alaska Natives living on tribal lands in the U.S. A hazards and vulnerability framework for understanding these impacts is first presented followed by context on the framework components, including climate, hydrologic, and ecosystem changes (i.e. hazards) and tribe-specific vulnerability factors (socioeconomic, political, infrastructural, environmental, spiritual and cultural), which when combined with hazards lead to impacts. Next regional summaries of impacts...
Abstract (from ScienceDirect): Climate change is affecting the benefits society derives from forests. One such forest ecosystem service is maple syrup, which is primarily derived from Acer saccharum(sugar maple), currently an abundant and widespread tree species in eastern North America. Two climate sensitive components of sap affect syrup production: sugar content and sap flow. The sugar in maple sap derives from carbohydrate stores influenced by prior year growing season conditions. Sap flow is tied to freeze/thaw cycles during early spring. Predicting climate effects on syrup production thus requires integrating observations across scales and biological processes. We observed sap at 6 sugar maple stands spanning...
Abstract (from SpringerLink): Western climate science and Traditional Ecological Knowledge (TEK) represent complementary and overlapping views of the causes and consequences of change. In particular, observations of changes in abundance, distribution, phenology, or behavior of the natural environment (including plants and animals) can have a rich cultural and spiritual interpretation in Indigenous communities that may not be present in western science epistemologies. Using interviews with Indigenous elders and other Traditional Knowledge holders, we demonstrate that assumptions about the nature, perception, and utilization of time and timing can differ across knowledge systems in regard to climate change.Our interviewees’...
This presentation provides an overview of the year-round migrations of the Cui-ui and Lahontan cutthroat trout within Pyramid Lake. This was developed for the "Climate Change Vulnerability of Native Americans in the Southwest" research project, funded by the USGS Southwest Climate Science Center.

Abstract (from AFS): Managing recreational fisheries in lake‐rich landscapes with diverse fish communities and anglers alike presents a social and biological challenge for managers. Understanding angler preferences is central to navigating these challenges and can aid in predicting shifts in angler behavior in response to management actions or changing fish populations. Species‐specific angler surveys do not incorporate tradeoffs inherent in multispecies fisheries, thus limiting their application to real‐world management issues. To better understand angler preferences in relation to realistic tradeoffs among different fishing opportunities, we conducted a survey of Wisconsin anglers in 2013–2014 that included questions...
Abstract (from DigitalCommons@University of Nebraska - Lincoln): Native American peoples of the Northern and Central Plains have long endured harsh climate conditions, such as floods and droughts, and they possess valuable traditional knowledges that have enhanced their resilience to these extreme events. However, in recent times, limited capacity to adapt to a rapidly changing climate combined with a lack of resources have increased tribes’ vulnerability to climate extremes and their associated impacts. In response, a number of projects have been developed to assist tribes with their self-identified climate- and drought-related needs, particularly in the context of on-reservation decision-making. In this case study,...

Abstract (from http://www.sciencedirect.com/science/article/pii/S002216941400225X): This study assesses the latest version, Version 7 (V7) Tropical Rainfall Measuring Mission (TRMM) Multi-satellite Precipitation Analysis (TMPA) rainfall estimates by comparison with the previous version, Version 6 (V6), for both near-real-time product (3B42RT) and post-real-time research products (3B42) over the climate-transitional zone in the southern Great Plains, USA. Two basins, the Verdigris River Basin (VRB) in the east and the Upper Washita Basin (UWB) in the west, with distinctive precipitation but similar vegetation and elevation, were selected to evaluate the TMPA products using rain gauge-blended products with WSR-88D...
Hydrologic extremes of drought and flooding stress water resources and damage communities in the Red River basin, located in the south-central United States. For example, the summer of 2011 was the third driest summer in Oklahoma state history and the driest in Texas state history. When the long-term drought conditions ended in the spring of 2015 as El Niño brought record precipitation to the region, there were also catastrophic floods that caused loss of life and property. Hydrologic extremes such as these have occurred throughout the historical record, but decision-makers need to know how the frequency of these events is expected to vary in a changing climate so that they can mitigate these impacts and losses....
Abstract: The recognition of climate change issues facing tribal communities and indigenous peoples in the United States is growing, and understanding its impacts is rooted in indigenous ethical perspectives and systems of ecological knowledge. This foundation presents a context and guide for contemporary indigenous approaches to address climate change impacts that are comprehensive and holistic. Tribal communities and indigenous peoples across the United States are reenvisioning the role of science in the Anthropocene; working to strengthen government-to-government relationships in climate change initiatives; and leading climate change research, mitigation and adaptation plans through indigenous ingenuity. Unique...
The Native Nations Climate Adaptation Program (NNCAP) was founded in 2015 with the mission to build capacity to work collaboratively with Native American tribes and indigenous populations in the western United States and Mexico. NNCAP received funds from the DOI Southwest Climate Science Center to carry out a “Tribal Adaptation Initiative.” One of the objectives of this initiativ ewas to conduct a preliminary assessment of tribal interest and capacity for adaptation across the Southwest. Twenty-six Native Nations participated in the NNCAP tribal climate change assessment and reported a wide array of involvement in climate change initiatives. This report highlights various strengths and capacity needs for climate...
