As environmental stressors continue to amplify, Lucania parva, or Rainwater Killifish, are expected to outlast other species in unpredictably fast changing environments, as they are unique in their ability to tolerate multiple salinities. The objective of this research is to understand what affects L. parva’s ability to tolerate salinity and discover the limitations the species might have to tolerating it. Understanding this fish’s biology will help with the conservation of aquatic ecosystems in Florida. Preliminary data and early trends suggest that during early larval stages, L. parva are plastic but the extent of their plasticity is limited as they cannot survive as well in extreme salinities.


This research was conducted through the Fuller Lab,, Department of Animal Biology, University of Illinois at Urbana-Champaign.

Financial support was provided by the National Science Foundation under grant #NSF REU 1559908/1559929, as part of the Phenotypic Plasticity Research Experience for Community College Students, through the University of Illinois at Urbana-Champaign Institute for Genomic Biology and Parkland College.
