“…The Red River shiner, which was historically more widely distributed in the Red River basin than the prairie chub ( Figure 8b; Buchanan, 1973;Hubbs et al, 2008;Miller & Robison, 2004;Wilde, 2015), is known in Arkansas from only two collections (Robison, 1974b) and none since impoundment of Lake Texoma in 1944 (Buchanan, Wilson, Claybrook & Layher, 2003). The peppered chub was historically found in the middle and upper reaches of the Arkansas River catchment (Figure 8c; Cross & Collins, 1995;Eisenhour, 1999;Luttrell, Echelle, Fisher & Eisenhour, 1999), but since the mid-20th century, has undergone large-scale declines and is extirpated from 90% of its historic range (Cross & Collins, 1995;Eberle, Ernsting, Tomelleri & Wells, 1993;Luttrell et al, 1999;Pigg, 1987). The species until recently was confined to two disjunct areas, a relatively stable population in the South Canadian River between Ute Lake, New Mexico and Lake Meredith, Texas (Bonner & Wilde, 2000), and a second potentially declining population in the Arkansas River in south-central Kansas (Luttrell et al, 1999;Perkin & Gido, 2011;Perkin, Gido, Costigan, Daniels & Johnson, 2015).…”
