Latitudes (°S) and region names from north to south (rows) showing the absence/presence of A. catenella in 2013–2016 (Presence is 1–2 cells). White cells indicate no periodic monitoring sampling sites that shown either pooled by year during summer-autumn periods in 2013–2014 (columns), or pooled by month in late 2015, early 2016 and dates of sampling days* in April and May 2016 (0 = not present in blue; 1 = only observed at one location in the region in yellow; M = observed at multiple locations in the region in red). *these sampling dates correspond to extraordinary samplings sites undertaken because of the exceptional bloom reported by animal deaths.
