Суточная ритмика светоизлучения Mnemiopsis leidyi A.Agassiz (Ctenophora: Lobata) // Материалы молодежной науч.-практ. конф. «Экологические проблемы Азово-Черноморского региона и комплексное управление прибрежной зоной» (29 сентября – 5 октября 2014 г.). – Севастополь: ЭКОСИ-Гидрофизика, 2014. – С. 89-94.https://repository.marine-research.ru/handle/299011/9525Light-emission circadian rhythmic of ctenophore Mnemiopsis leidyi A.Agassiz 1865 - recent alien to the Black Sea has been researched. 2 peaks of light-emission intensity are revealed: in 01 h nights and day in 13 h. The bioluminescence amplitude of ctenophores under mechanical and chemical methods of stimulation achieves the maximal values in 01 h and minimal in 10 h. Under the conditions of ctenophores in the dark the night peak of their light-emission intensity 2.5 times exceeds the day. Presence of light-emission photoinhibition of ctenophores was revealed. Energy of light-emission in 01 h is maximal at the individuals contained in the dark, and 5 times more that ones of individuals contained in the light. The substantiated conclusion that the light-emission endogenous rhythm of ctenophore can be caused as daily changes of their nutrition, metabolism and reproduction, as circadian fluctuation of their bioluminescent reaction substratum.ru
