Distribution Patterns of Large Jellyfish and Their Effects on the Zooplankton Community in the Northern Chinese Coastal Seas during the Summer of 2021

The northern Chinese coastal seas have been observed to constitute a large jellyfish blooming hotspots during the las decades. spatial distribution of abundance and biomass was investigated in this area through bottom trawl survey summer 2021. Nemopilema nomurai, Cyanea spp., Aurelia coerulea, Aequorea Ulmaridae (undefined sp.) were identified investigation. realized niches three most abundant species (N. A. coerulea) measured maximum entropy (MaxEnt) model explain their patterns. nomurai used as representative estimate feeding rate pressure on zooplankton. During N. blooms, potential consumption zooplankton by enormous even exceeded productivity regions where assembled study. Reductions absolute relative noted small copepods at mid-bloom bloom stations compared non-bloom stations. relationships with study would be helpful for understanding biogeographic ecological roles under future climate change scenarios.
