Invasive species create risks to ecological communities. Recently, in Puerto Rico, sharptooth walking catfish (Clarias batrachus) were discovered as a new invasive species. This project is using environmental DNA (eDNA) to sample streams and help inform where physical removal efforts of this invasive species could best be allocated.
Amanda Rosenberger, PhD
Amanda is the Assistant Unit Leader of the Tennessee Fisheries CRU. She is from Virginia. Her research interests are in the ecology and conservation of freshwater species, including fish, crayfish, and mussels, with an emphasis on the role of ecological processes in shaping aquatic species' distributions, population characteristics, and community structure.
Research Interests
Amanda's research interests are in the ecology and conservation of freshwater fishes with an emphasis on the role of ecological processes in shaping fish distributions, population characteristics, and community structure. Conservation problems are best addressed at multiple scales; therefore, she is interested in the spatial and temporal dynamics of these patterns at both local and landscape scales. She is particularly interested in investigating mechanistic relationships between fish and physical and biotic features of the environment and how human intervention, nonnative species, and climate change can alter those relationships.

Science and Products
Arctic Lake Food Webs
From 2011 to 2013 we investigated freshwater food webs of Arctic Coastal Plain lakes in Alaska to improve our understanding how Arctic freshwater food webs may respond to landscape change the warmer, drier future.
