“…The recurring late summer (JulyAugust) cHABs of the Baltic are dominated by the taxa Nodularia spumigena, Aphanizomenon flos-aquae and, to a minor extent, by Anabaena spp. and other species from the order Nostocales, family Nostocaceae (Hajdu et al, 2007;Hällfors, 2004;Kanoshina et al, 2003;Karjalainen et al, 2007;Sivonen et al, 2007;Celepli et al, 2017). While the Nodularia genus is usually prevalent, changes in the composition of the community have been observed from the early to the late stage of the cHAB and from one year to another, resulting in a large variation in its features over time (Finni et al, 2001;Hajdu et al, 2007;Kahru et al, 1994;Wasmund, 1997).…”
