Mean gene abundance of anatoxin synthetase genes (anaC), microcystin synthetase genes (mcyE), and saxitoxin synthetase genes (sxtA) in water samples compared to photosynthetically active radiation (PAR) data collected from the end of a dock (site A) and the adjacent shoreline (site B) over 24 h, at Ash River Boat Docks on Kabetogama Lake, MN, September 9–10, 2021. Note the differences in scale between sites for gene abundances.
