Chemical composition and egg production capacity throughout bloom development of ctenophore in the northern Adriatic Sea.

High abundances of gelatinous zooplankton (GZ) can significantly impact marine ecosystem by acting as both sink and source of organic matter (OM) and nutrients. The decay of GZ bloom can introduce significant amount of OM to the ocean interior, with its variability influenced by GZ life traits and environmental factors, impacting microbial communities vital to marine biogeochemical cycles. The invasive ctenophores has formed massive blooms in the northern Adriatic Sea since 2016.
