Fig. 2.

Presence of the mcyE gene and microcystins or nodularins in different regions. The number of specimens is presented on the x axis. Specimens with the mcyE gene and microcystins or nodularins detected are in red, samples with only the mcyE gene are in orange, and without the gene or toxins are in gray. Percentages at the end of the bars are the proportions of specimens having the mcyE gene and/or toxins. Only regions with a specimen number over 10 are included in the chart. S Finland refers to southern Finland, and Lapland contains areas in Finland and Sweden north of latitude 65°.
