Rhinichthys cataractae has a wide distribution across the country and can be found in the majority of temperate habitats across North America (Girard & Angers, 2011). Similar to other species that inhabit northeast Iowa streams, its present-day distribution has been heavily influenced by Pleistocene glaciations (Girard & Angers, 2006). Corresponding to the distinct landscape and glacial history of northeast Iowa, the longnose dace is distributed almost exclusively in the northeast comer of Iowa (Figure 3). Investigation of the genetic diversity of this species will help clarify what steps need to be taken to ensure their survival and success, and may reveal the processes that led to the current distribution observed in Iowa. This study used genetic techniques to explore the diversity of longnose dace to contribute to future conservation efforts.
