Data was taken at the Methow River near Pateros, WA USGS (12449950) flow station. (waterdata.usgs.gov/wa/nwis/uv?12449950). The flow data from 2009 through 2013 is used in the whitefish movement paper: "Spatio-temporal variability in movement, age, and growth of mountain whitefish (Prosopium williamsoni) in a river network based upon PIT tagging and otolith chemistry." Canadian Journal of Fisheries and Aquatic Sciences, 2014, 71(1): 131-140, 10.1139/cjfas-2013-0279

Many fish species, including mountain whitefish and bull trout, need a variety of habitat types throughout their different life stages that include appropriate water temperatures, flows, refugia from predators, and adequate food. Key to a fish finding and using these different habitats is the connectivity between them. Changing conditions in the future, including increased air and water temperatures, are expected to impact many fish populations, as well as the rivers, streams, and habitats where they’re found. This project, jointly funded by the Great Northern Landscape Conservation Cooperative, focused on the Methow River Basin in the arid east-central part of Washington State. The project team used data on fish...

The “Dieoff” contains every year’s cheatgrass dieoff maps as .png files. This also contains the Dieoff Probability map, also as a .png file.
This paper describes a publicly available, long-term (1915–2011), hydrologically consistent dataset for the conterminous United States, intended to aid in studies of water and energy exchanges at the land surface. These data are gridded at a spatial resolution of latitude/longitude and are derived from daily temperature and precipitation observations from approximately 20 000 NOAA Cooperative Observer (COOP) stations. The available meteorological data include temperature, precipitation, and wind, as well as derived humidity and downwelling solar and infrared radiation estimated via algorithms that index these quantities to the daily mean temperature, temperature range, and precipitation, and disaggregate them...

The purpose of this project was to (1) provide an internally-­consistent set of downscaled projections across the western U.S., (2) include information about projection uncertainty, and (3) assess projected changes of hydrologic extremes. These objectives were designed to address decision support needs for climate adaptation and resource management actions. Specifically, understanding of uncertainty in climate projections - in particular for extreme events - is currently a key scientific and management barrier to adaptation planning and vulnerability assessment. The new dataset fills in the Northwest domain to cover a key gap in the previous dataset, adds additional projections (both from other global climate models...

The bull trout, listed as threatened under the Endangered Species Act, is well adapted to the cold waters of the Northwest. Recent changes in climate have caused winter flooding and warmer summer water temperatures in the region, reducing the cold-water habitats that bull trout depend on. The southernmost bull trout populations, found in Oregon, Washington, Idaho, Montana, and Nevada, are currently restricted to small reserves where the coldest waters still exist. These shrinking habitats have created a severed environment being further split by dams, poor water quality, and invasive species. The goal of this project was to determine how these factors threaten the species regionally by using predictions of stream...
Habitat loss and climate change constitute two of the greatest threats to biodiversity worldwide, and theory predicts that these factors may act synergistically to affect population trajectories. Recent evidence indicates that structurally complex old-growth forest can be cooler than other forest types during spring and summer months, thereby offering potential to buffer populations from negative effects of warming. Old growth may also have higher food and nest-site availability for certain species, which could have disproportionate fitness benefits as species approach their thermal limits. We predicted that negative effects of climate change on 30-year population trends of old-growth-associated birds should be...

The Oregon Water Science Center provided the scientific, bibliographic, and administrative support needed to prepare a Science Agenda for the Northwest Climate Science Center (NW CSC). The Science Agenda is the basis for guiding the science program of the NW CSC.

The objective of this study was to determine why certain stream insects tend to be found in certain temperature ranges. Many federal, state and local agencies use stream insects to monitor the health of freshwater ecosystems. While the temperature ranges for some insects are often inferred from the temperature of the waters where they were collected, this inference is coarse at best and problematic at worst. Stream temperatures fluctuate a lot during the year and temperature may or may not control where an insect lives. Field insects were collected and sent to a laboratory for testing several temperature endpoints, particularly at higher temperatures. Respiration, breathing rate, and some physical activities were...
We developed a website which details preliminary work we have conducted on cheatgrass dieoff in the Great Basin near Winnemucca, NV.
Abstract (from http://onlinelibrary.wiley.com/doi/10.1111/ddi.12456/full): Climate changes are anticipated to have pervasive negative effects on biodiversity and are expected to necessitate widespread range shifts or contractions. Such projections are based upon the assumptions that (1) species respond primarily to broad-scale climatic regimes, or (2) that variation in climate at fine spatial scales is less relevant at coarse spatial scales. However, in montane forest landscapes, high degrees of microclimate variability could influence occupancy dynamics and distributions of forest species. Using high-resolution bird survey and under-canopy air temperature data, we tested the hypothesis that the high vagility of...
U.S. States (Generalized) represents the fifty states and the District of Columbia of the United States. The Northwest Climate Science Center (NW CSC) Science Agenda outlines the overall science direction for the NW CSC in 2012-2016. It forms an integral part of the NW CSC Strategic Plan for 2012-2016 and was developed with input from cultural and natural resource managers in the Northwest. The Science Agenda guides the NW CSC and its Executive Stakeholder Advisory Committee ( ESAC) in the identification of annual and long-term research priorities to be funded by the NW CSC.
