Marine Ecological Journal| Zusammenfassung: | Distinctions of the Black Sea ctenophores Pleurobrachia pileus, Mnemiopsis leidyi, Beroe ovatа and Bolinopsis vitrea reactions on the temperature change are revealed. Their confinedness to the layers with different temperature has been shown and thermal dependences of eggs spawning, rate of development and growth of animals larvae has been specified. Among living now in the Black sea ctenophores pleurobrachia is cold-loving species, while mnemiopsis is more thermophilic. Influence of temperature conditions on ctenophores bioluminescence characteristics has been defined. An optimum of bioluminescent reaction of M. leidyi is registered at temperature 26 ± 1 ºС, and B. ovata – at 22 ± 1 ºС. The minimum of light-emission for both species of ctenophores has been registered at 10 ± 1 ºС. |
