Abstract The distribution and future fate of ectothermic organisms in a warming world will be dictated by thermalscapes across landscapes. That is particularly true for stream fishes and cold-water species like trout, salmon, and char that are already constrained to high elevations and latitudes. The extreme climates in those environments also preclude invasions by most non-native species, so identifying especially cold habitats capable of absorbing future climate change while still supporting native populations would highlight important refugia. By coupling crowd-sourced biological datasets with high-resolution stream temperature scenarios, we delineate network refugia across >250 000 stream km in the Northern...

Stream temperature data will be compiled from federal and provincial government agencies, as well as other data holders in British Columbia which will be housed in an interagency database. Spatial statistical models for river networks like those used for NorWeST will be used with these data to develop a consistent set of high-resolution predictions for all streams and reaches within streams for a pilot area within the Cascadia ecotypic area of the GNLCC (i.e., middle Fraser River and Okanagan River basins). The pilot area work would entail development of technical protocols so that future efforts could be scaled broadly across BC and the northern half of the GNLCC to ultimately provide a consistent set of international...

Water in the western United States is disappearing, and several states are facing severe water shortages as drought conditions worsen. Many streams are drying up, and there is growing concern that this trend will only continue as climate change produces warmer and drier conditions. The loss of stream ecosystems has far reaching ecological, social, and economic implications. Species that depend on these ecosystems for habitat will be at greater risk of extinction and humans will lose vital sources of water relied upon for agriculture, drinking water, and recreation. This project aimed to identify how water availability is changing in the West, focusing specifically on when and where streams go dry. Researchers...

Stream temperature data will be acquired from federal and provincial government agencies, as well as other data holders in British Columbia to eventually be housed in an interagency database. Spatial statistical models for river networks like those used for NorWeST will be used with existing and readily available stream temperature data to develop a consistent set of high-resolution predictions for all streams and reaches within two pilot areas: an interior location represented by the Nicola River watershed in the Great Norther LCC and a coastal location represented by the Somass River watershed within the North Pacific LCC (Panels 1 & 2 respectively in Fig 1). Work in these proposed pilot areas would include processing...
