Abstract: We analyzed the main factors that controlled the prey-predator dynamics of two invasive ctenophores, Mnemiopsis leidyi and Beroe ovata in the Black Sea using a demographic model. We assessed the bottom up cascading effect from edible zooplankton to its consumer M. leidyi and its predator B. ovata. For these purposes, we used life cycles of both ctenophores (ova, larva, juvenile, transitional and adult stages), variability of annual phenology and physiological features obtained from our field observations and experiments made in the north-eastern Black Sea over 27 years, combined with a long-term change in temperature and food availability for both ctenophores.
