A Heatmap of Grass Pickerel movements in Beaver Creek (Ontario), summarized from 2009–2013 and by year. B Alluvial plot of movements made by Grass Pickerel in Beaver Creek, 2009–2012. Movements made in 2013 were not included as an alluvial plot as there were few (n = 6) movements made. Nodes represent sites, with advancing stages representing subsequent (and different) site detections. Node size is scaled to the number of movements started or ended from the site, and the color corresponds to the branch of the watershed
