Rate of global biodiversity loss increased significantly during the 20th century associated with human environmental alterations. Specifically, mismanagement of freshwater resources contributed to historical and contemporary loss of stream-dwelling fish diversity and will likely play a role in determining the persistence of species in the future. We present a mechanistic pathway by which human alteration of streams has caused the decline of a unique reproductive guild of Great Plains stream-dwelling fishes, and suggest how future climate change might exacerbate these declines. Stream fragmentation related to impoundments, diversion dams and stream dewatering are consequences of increasing demand for freshwater resources...

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 Northern LCC and a coastal location represented by the Somass River watershed within the North Pacific LCC. Work in these proposed pilot areas would include processing of spatial data and applying...
