“…In addition, it is important to consider the different stages of the life cycle, such as benthic polyps, since they are crucial to understanding ''bloom'' dynamics (Purcell, 2007;Willcox et al, 2008;Bayha & Graham, 2009;). Because ''blooms'' of Benović & Lučić (2001) ''Bloom'' as an abnormal event Graham et al (2001) Differences between ''apparent bloom'' and ''true bloom'' Mills (2001) ''Normal'' and ''abnormal blooms'' (''true bloom'') Nival & Gorsky (2001) Convenience concept of ''bloom'' Parsons & Lalli (2002) Differences between ''apparent bloom'' and ''true bloom'' Purcell et al (2007) ''Bloom'' related to reproduction, i.e., ''true bloom'' Boero et al (2008) ''Bloom'' (multispecific) is different from ''outbreak'' (monospecific); seasonal (''normal bloom'') or unexpected (''abnormal bloom'') Daryanabard & Dawson (2008) Differences between ''apparent bloom'' (aggregations) and ''true bloom'' Genzano et al (2008) ''Bloom'' as an abnormal event; discussion on the convenience concept of ''bloom'', and differences between ''apparent'' and ''true bloom'' Albert (2009) Swarm and aggregation (''apparent bloom'') Definition of mass occurrence, ''normal'' and ''abnormal blooms'' (''true blooms''), and swarm (''apparent bloom'') ''Normal'' and ''abnormal blooms'' (''true bloom'') and ''apparent bloom'' Definition of ''true bloom'' (''normal'' and ''abnormal''), ''apparent bloom'' (aggregations and swarms), mass occurrence, and accumulations Lilley et al (2009) ''Bloom'' synonym of large aggregations Purcell et al (2009) ''Bloom'' synonym of ''outbreak'' Licandro et al (2010) ''Bloom'' as a synonym of ''outbreak'', related to the density of organisms Purcell (2012) ''Bloom'' as unusually high abundance (i.e., ''abnormal bloom'') synonym of ''outbreak'' Brotz et al (2012) ''Bloom'' defined as increase in presence, numbers, or biomass large medusae primarily are responsible for the negative impacts reported (Uye, 2008;Richardson et al, 2009), a biased view in the characterization of ''blooms'' neglects some inconspicuous groups, as the hydromedusae ). Nevertheless, examples of hydromedusan ''blooms'' are in the literature (e.g., Purcell & Grover, 1990;Mianzan et al, 2000;Raskoff, 2001;Stefani et al, 2010;…”
