Joshua Leffler is an **Associate Professor** and **Assistant Department Head** in the Department of Natural Resource Management at South Dakota State University. He holds a B.S. in Biology from the University of Utah (1994) and a Ph.D. in Biology from the University of New Mexico (1999). His research focuses on plant physiological ecology and ecosystem ecology, particularly in arid lands, grasslands, and Arctic systems. He investigates climate change impacts on plant communities, greenhouse gas emissions, and grazing management effects. Leffler serves on editorial boards for *Plant Ecology* and *Bioscience*, and is active in organizations like the Ecological Society of America and Society for Range Management.
Research Interests: His work addresses climate change drivers (e.g., warming, precipitation shifts), grazing technology impacts on carbon/N cycling, and Arctic coastal wetland dynamics. He explores how phenological mismatches and herbivore timing affect Arctic plant traits and ecosystem processes.
Professional Contributions: Leffler has authored/co-authored over 50 peer-reviewed articles, focusing on plant-soil interactions, greenhouse gas fluxes, and restoration ecology. His studies often integrate field experiments, remote sensing, and climate modeling to address ecological challenges in rangelands and Arctic ecosystems.
Affiliations: Based in the McFadden Biostress Laboratory (Room 141C), he advises students on courses like *Ecosystem Ecology* (NRM464/564) and collaborates on grants exploring Arctic vegetation responses to climate change. His work emphasizes practical solutions for sustainable land management and ecological resilience.
