Since large river tributaries of the upper Mississippi River basin (UMRB) are known to contain high fish biodiversity (Burr and Page, 1986; Neebling and Quist, 2010; Pierce et al., 2013), the majority of the 68 fish SGCN are primarily distributed in Iowa's large nonwadeable rivers.
These river drainages form the majority of the UMRB in Iowa and were chosen because they represent high levels of fish biodiversity.
In this case, groups represent a regional species pool (i.e., rivers in the UMRB) at two different time periods (i.e., assessment periods).
