Abstract of Smith, G.R., and D.R. Fisher. 1970. Factor analysis of distribution patterns of Kansas fishes, pp. 259-277 in J.K. Jones (ed.) Pleistocene and Recent environments of the central Great Plains. Univ. Kansas Press, Lawrence.

The fishes of Kansas sort into regional groups based on available water and drainage barriers and connections. The highest species density is in the wettest (southeastern and eastern) parts of the state. Only one species pair demonstrates clear complimentarity.
