Marine Ecological Journal| Zusammenfassung: | The changes of the biophysical characteristics of light-emission in ontogenesis of ctenophore Mnemiopsis leidyi Agassiz - recent introducer to the Black sea has been researched. It is established, that amplitude of larva individuals was 3.5 times more, and energy of light-emission 2 - 3 times more, than similar parameters of the bioluminescence in eggs of ctenophores. Amplitude and energy of light-emission of quite recently caught ctenophore (in control) were some orders more than similar parameters in ctenophores after spawning.The maximum bioluminescence amplitude values were observed in the group of ctenophores with eggs-laying. It was registered a significant increase of light-emission characteristics of ctenophores with increasing body. Substantiated conclusion, that distinctions in the bioluminescence parameters of ctenophores in ontogenesis can be caused by ontogenetic features of their biochemical structure and quantity involved in bioluminescent reaction photocytes. |
