The closure assumption of many abundance models, that individual animals are present throughout the survey season, often is inconsistent with field data. The effects of closure-assumption violations on estimators of abundance and associations between abundance and covariates are not fully understood. Furthermore, one’s definition of abundance affects these estimates. We used simulated data on breeding birds to explore how permanent, non-random immigration and emigration that violate the closure assumption affect estimates from N-mixture abundance models and naïve models (models that do not account for imperfect detection). This is the first work to evaluate the effect of permanent immigration and emigration on estimates...

Climate change is one of the most pressing issues facing natural resource management. The disruptions it is causing require that we change how we consider and implement conservation and resource management in order to ensure the future of habitats, species, and human communities, whether that means adopting new management actions or adjusting the ways in which existing actions are implemented. However, practitioners often struggle with how to identify and prioritize specific climate adaptation actions, which are taken to either increase/enhance resilience or decrease vulnerability in a changing climate. Management actions may have a higher probability of being successful if they are informed by available scientific...

These data can be used to replicate the application of MWBMglacier as described in two journal articles: 1) Enhancement of a parsimonious water balance model to simulate surface hydrology in a glacierized watershed (in review), and 2) Hydrologic regime changes in a high-latitude glacierized watershed under future climate conditions (doi:10.3390/w10020128). These simulations provide results from historical and 12 future general circulation model scenarios for the period 1949-2099 to determine the potential effects of climate change on the hydrology and water quality of a snow-dominated mountainous environment. In addition to the inputs and outputs, this Data Release includes summaries of the input and output data...
The goal of the Wetlands in a Changing Climate project was to provide consistent, wall-to-wall data on wetland location, historical hydrologic dynamics, and projected climate change impacts on hydrologic dynamics. We worked with managers to determine what products would be most informative, and what approach would help them use these data products to develop recommendations for climate-smart conservation of wetlands across the Columbia Plateau.

Climate change is one of the most pressing issues facing resource management. The disruptions it is causing require that we change the way we consider management in order to ensure the future of habitats, species, and human communities. Practitioners often struggle with how to identify and prioritize specific climate adaptation actions (CAAs). Management actions may have a higher probability of being successful if they are informed by available scientific knowledge and findings. The goal of the Available Science Assessment Process (ASAP) was to synthesize and evaluate the body of scientific knowledge on specific, on-the-ground CAAs to determine the conditions, timeframes, and geographic areas where particular CAAs...

A compilation and content analysis of gray literature (e.g., shoreline management plans, climate change strategy documents) from the Pacific Northwest - Washington, Oregon, northern California -written between 1993-2016, and categorized as to the ways in which climate adaptation actions related to sea level rise appear in these documents.

This project was designed to use the combined strengths of the cooperators to address their concerns stemming from the degradation of arid environments in the Great Basin. The project aimed to identify the regional ecological and social costs and benefits of both immediate hydrologic modifications (low-profile constructed dams) and longer-term restoration of beavers (Castor canadensis) to these landscapes. Use of these techniques by ranchers and managers of public lands depends on these costs and benefits as well as social context and attitudes; the project aimed to assess these as well. Finally, implementation of hydrologic modifications depends on communication of benefits and costs to stakeholders who may choose...
Depressional wetlands in the Columbia Plateau are valuable habitats because they maintain surface water into or throughout the dry summers. The source of that moisture—surface runoff from surrounding areas, or groundwater in local aquifers—may determine if these wetlands are seasonal, permanent, or semi-permanent. Helping these wetlands continue to provide habitat and other services requires understanding how these flooding and drying patterns (their hydrology) have changed in the past, and how projected changes in climate might affect them. The goal of this project was to develop wall-to-wall maps of wetlands across the region, coupled with detailed 30-year hydrographs of historical (1984-2014) fluctuations in...
The past decade has seen a rapid rise in beaver-related stream restoration (BRR) using beavers and beaver dams (real or artificial) as a tool. Potential benefits of this low-cost, nature-based restoration approach include restoring aquatic and riparian habitat and recovering of threatened species dependent on it, improving water availability and stream flow regulation, reducing erosion and stream incision, and supporting climate change adaptation. Although the ecological restoration literature acknowledges the importance of addressing the human dimensions of restoration, there is a gap regarding the human dimensions of BRR. To help fill this gap we examined six projects involving riparian revegetation or artificial...

Abstract (from http://onlinelibrary.wiley.com/doi/10.1002/2015JF003789/abstract): A module to simulate glacier runoff, PRMSglacier, was added to PRMS (Precipitation Runoff Modeling System), a distributed-parameter, physical-process hydrological simulation code. The extension does not require extensive on-glacier measurements or computational expense but still relies on physical principles over empirical relations as much as is feasible while maintaining model usability. PRMSglacier is validated on two basins in Alaska, Wolverine, and Gulkana Glacier basin, which have been studied since 1966 and have a substantial amount of data with which to test model performance over a long period of time covering a wide range...
The large, highly glacierized Copper River basin is an important water resource for the south‐central region of Alaska. Thus, information is needed on the reaction of its hydrologic timing and streamflow volumes to historical changes in climate, in order to assess the possible impact of future changes. However, the basin is remote, and therefore, it has proved difficult to collect field data in a frequent temporal and spatial manner. An extension of the distributed‐parameter, physical‐process code Precipitation Runoff Modeling System, PRMSglacier, has been specifically developed to simulate daily hydrology without requiring extensive input data. In this study, PRMSglacier was used to characterize the hydrology of...
