JBS-04 To bloom or not to bloom? Factors affecting hydrozoan abundances

 

True (or remarkable) blooms are often considered as such mainly because of high biomass.However, we believe that especially high abundances of jellies should be considered ‘blooms’, even if they are  short-­‐lived and low biomass, such as for most hydromedusae. Therefore, we invite papers that consider all aspects of hydrozoans that contribute to the occurrence or formation of blooms. We would like to emphasize biological and  ecological mechanisms leading to high abundances the hydroid and medusa stages of hydromedusae. Siphonophores will be covered in another session.
