Research in the Kunza Laboratory examines the influence of environmental change on aquatic ecosystem processes and functions.  In particular, we are interested in linkages among biogeochemistry, ecosystem ecology, and food web dynamics in aquatic ecosystems with an emphasis on applying our scientific findings to broader audiences.  Currently, we are examining the influence of environmental alterations to ecosystems including nuisance and invasive species bacterial loading and pathogenicity, nitrogen loading, and hotspots of oligotrophication below dams. Dr. Kunza strives to increase interdisciplinary research with colleagues at South Dakota School of Mines and Technology as well as via regional, national, and international collaborations. 

Dr. Kozak has over 25 years of GIS and remote sensing experience and is applying it to regional climate and environmental issues. His research has included issues related to surface water salinization, energy, natural hazards, climate change, flood plain management, hazard identification, mitigation planning, threat and hazard identification, and assessment with Tribes, tribal colleges, at-risk communities, and non-profits across the United States. Dr. Kozak believes that outreach to key community stakeholders is critical, so that research and results become an active part of decision-making and problem-solving.

Dr. Long-Fox’s research is focused on evaluating interactions between anthropogenic impacts, and organism morphology and evolution, as applicable to conservation paleobiology. Her research expertise spans phylogenetics, biodiversity, and ecosystems, emphasizing the examination of modern systems. She investigates live-dead fossil assemblages to unravel baseline information predating human activities to compare to modern systems. Through research, Dr. Long-Fox aspires to contribute to a comprehensive understanding of how anthropogenic influences have shaped and continue to shape biological communities. By identifying key evolutionary and ecological patterns, she aims to inform evidence-based conservation strategies that mitigate human impacts and foster resilience in natural systems.
