People

Research in our lab is dedicated to understanding how anthropogenic activities alter community structure and ecosystem processes (e.g., productivity, decomposition, and biogeochemical cycling) in freshwater ecosystems. Much of our research has focused on the impacts of consumers on basal food resources, community structure, and nutrient dynamics in streams and wetlands. We attempt to view our work through a social-ecological lens, acknowledging the powerful impacts that public policy and economic considerations can have on the quality and quantity of freshwater resources, the abundance and diversity of aquatic organisms, and the function of freshwater ecosystems. In an attempt to translate scientific knowledge to actionable outcomes, we actively work with community groups and local, state, and federal employees to develop programs that integrate stakeholder concerns into our research planning. Integrating a diverse set of perspectives into our work is important to develop a more comprehensive understanding of freshwater science. We embrace our lab members’ differences in gender, color, disability, ethnicity, age, family or marital status, gender identity or expression, language, national origin, ability, political affiliation, race, religion, sexual orientation, socioeconomic status, veteran status, and other characteristics. Please feel free to review our lab statement of culture here. You may also review the materials we ask new members of our team to review to support the culture we hope to create and sustain here. We are excited to welcome new members to our research team.

Denzell began his research in aquatic ecology as an intern in the lab of Dr. Alan Christian as part of an REU at the University of Massachusetts, Boston. As part of this project, he conducted research comparing the physical, chemical, and biological effects of different methods of stream restoration on in-stream conditions. After graduating Norfolk State University with a BS in Biology in 2013, Denzell worked as a Restoration Ecology apprentice at The Wilds Conservation Center in Cumberland, OH, under the direction of Shana Byrd. Through this apprenticeship, he designed an experiment seeking to understand the in-stream impacts of mechanical riparian invasive plant removal in urbanizing environments. In 2015, Denzell began working as an hourly researcher in the Aquatic Ecology Lab at the Joseph W. Jones Ecological Research Center under the direction of Dr. Paul McCormick. While in the McCormick Lab, he conducted routine chemical and biological sampling of the Ichauway-Notchaway Watershed to estimate the effects of human-induced low flows on rivers and streams. Denzell also worked in the laboratories of Dr. Steve Golladay and Dr. Steven Brantly, investigating the ecological and hydrological conditions of the lower Flint River Basin and the physiological characteristics of longleaf pine. Denzell’s graduate research in the Capps Lab examines the effects of urbanization on the structure and function of aquatic macroinvertebrate  communities in Georgia. Denzell is a part of the Odum School of Ecology and the program in Integrative Conservation (ICON) at the University of Georgia. In 2018, Denzell was one of approximately 65 students in the US who was awarded a Ford Predoctoral Fellowship. Denzell became a PhD Candidate in the fall of 2020.

Anuja Mital is a Ph.D. student through the Integrated Conservation (ICON) program, and is co-supervised by Krista Capps and John Maerz. She completed a BS double majoring in Botany and Zoology in 2014, and a Masters in Wildlife Biology in 2016 from India, studying the community ecology and resource partitioning of freshwater turtles in the Ganges river basin. She has also documented freshwater turtle populations across the Brahmaputra river in NE India and her interests include population ecology of aquatic reptiles, the hydrology and flooding of large rivers, and freshwater habitat management alongside conservation education and outreach. Anuja is also the co-founder of ‘Freshwater Turtles and Tortoises of India‘, a citizen-science initiative to increase awareness and research on these taxa in India. At UGA, she plans to continue to explore freshwater food webs in the Brahmaputra with an emphasis on turtle ecology and use a systems approach to explore socio-ecological systems dynamics in the Brahmaputra to support turtle conservation in the region.

Kyle Connelly

kyle.Connelly@uga.edu

Originally from Northeast Ohio, Kyle earned his B.S. in Wildlife and Fisheries Resources from West Virginia University in 2012.  During that time, he assisted with a number of water quality monitoring projects for both a local watershed advocacy organization and a regional government agency.  Through those practical experiences, he gained a particular interest in the issues and management implications surrounding heavily impacted aquatic systems.  After graduating, Kyle spent two years in the Philippines as a Coastal Resource Management Volunteer with the Peace Corps, where he facilitated the collection of local community and environmental data and helped write a five-year environmental management plan for the area.  Kyle, now a M.S. student in the Conservation Ecology and Sustainable Development program at UGA, seeks to couple his practical experiences with new skills and perspectives to help address environmental perturbations in communities.  He is most interested in exploring community and ecological threats and opportunities at the watershed scale through issue-driven research.  His thesis work focuses on how the spatial arrangement and management characteristics of wastewater infrastructure impacts local stream water quality in Athens-Clarke County and how those relationships may correlate with socio-demographic data.
