Relationship between native and nonnative fish presence and the five components of the hydrograph in streams of the Mogollon Rim emphasis area, Arizona

***THIS IS A NOTICE OF SINGLE SOURCE AWARD-NOT A RFP***The mission of the Arizona Fish and Wildlife Conservation Office (AZFWCO, U.S. Fish and Wildlife Service, Fish and Aquatic Conservation Program, Region 2) includes recovering endangered and threated fish species through research, monitoring, management, and development of management recommendations. A primary threat to native fish populations in Arizona is competition and predation by nonnative fish that are ubiquitous in Southwest streams and lakes. Yet, in a few notable Arizona streams, natives and nonnative appear to coexist in relatively stable numbers. The cause of this unique and rare phenomenon is unknown and AZFWCO has begun investigating this pattern, initially focusing on factors associated with steam flow and the hydrograph. At the same time, U.S. Geological Survey Arizona Cooperative Fish and Wildlife Research Unit at the University of Arizona have begun researching factors potentially linked to this same phenomenon including variables such as instream habitat types, riparian habitat types, and the five standard components of a stream hydrograph. This single source funding opportunity is intended for AZFWCO to combine forces and provide additional funding to the U.S.G.S. Cooperative Research Unitâ¿¿s ongoing research to expand investigations focusing on instream flow and the hydrograph.**SEE FULL TEXT NOFO FOR MORE INFORMATION**
