Linking genome to phenome to predict adaptive responses of organisms to changing landscapes. This project is advancing fundamental knowledge regarding the mechanisms that rule genome to phenome pathways to predict how species adapt to external stressors and a changing environment. It is helping to translate this knowledge into evidenced-based resource management policies and practices for more adaptive and resilient species and landscapes. Principal collaborators with the Stream Ecology Center as part of this large project include Lizzie Jossie (graduate student), Drs. Kitty Griswold, Morey Burnham, Donna Delparte, Ernest Keeley, Janet Loxterman, Georgia Hart Fredeluces, Laticia Herkshan, and Travis Seaborn.  Integrated efforts at Boise State University and University of Idaho were led by Drs. Jen Forbey and Chris Caudill, respectively, and the statewide PI on the award is Dr. Andy Kliskey. Funded by the National Science Foundation-EPSCoR Program. For details, see project web page.

Past Research Projects

Managing Idaho's Landscapes for Ecosystem Services ("MILES"). This project was part of a statewide program involving dozens of scientists aimed at advancing Idaho's capacity to resolve the complex social-ecological processes associated with urban growth-influenced changes to ecosystem services. The project improved the ability to provide science-based decision support needed to sustainably manage Idaho's resources. Collaborators at Idaho State University included Drs. David Rodgers (administrative lead), Kathleen Lohse, Danelle Larson (former postdoc), Jade Ortiz, Carolyn Macek, Sarah Stalder, Scott Greeves (graduate students), Rebecca Hale, Antonio Castro, Donna Delparte, Shannon Kobs-Nawotniak, Rosemary Smith, & Sarah Godsey (Biology & Geology), Donna Lybecker, Jim Stoutenborough & Mark McBeth (Political Science), Yolonda Youngs, Rob Edsall and Kevin Marsh (History) and Katrina Running (Sociology). Integrated efforts at Boise State University and University of Idaho were led by Drs. Shawn Benner and John Anderson, respectively. Funded by the National Science Foundation-EPSCoR Program. For details, see project web page.
