Ecological role of bioluminescence of Black sea ctenophores.

Bioluminescence, which is a manifestation of the vital activity of an organism in the form of electromagnetic radiation in the visible area of the spectrum, is a highly important ecological and optical factor of the marine environment. Until recently, it was believed that microplankton - bacteria and dinoflagellates - exceptionally contribute to the formation of the bioluminescence field in the Black Sea, as well as in other regions of the World Ocean. However, the ctenophores  A.

Impact of hypoxia conditions on the Mnemiopsis leidyi A. Agassiz, 1865 bioluminescence.

The findings of the study on the impact of hypoxia on the glow of the Black Sea ctenophore Mnemiopsis leidyi A. Agassiz, 1865 of three size groups (20-30, 30-45, and 45-60 mm) were obtained under experimental conditions. Peculiarities of ctenophore bioluminescence were studied during mechanical and chemical stimulation under the conditions of normoxia (at an oxygen concentration of 5.
