596 ERRATUM / ERRATUM Erratum: Influence of spatial positioning within stream networks on fish assemblage structure in the Kansas River basin, USA Darren J. Thornbrugh and Keith B. Gido Ref.: Can. J. Fish. Aquat. Sci. 67: 143-156 (2010). Figure 1a of this article is a conceptual diagram representing hypothesized movement patterns. The arrows represent species or sizes classes of fish and their potential movements through confluence zones and among streams of different size. In the original article, some of the arrows for confluence exchange and network dispersal are partly missing; the correct diagram for Fig. 1a is as follows: Fig. 1a. Received 22 January 2010.
