Range expansions of scyphozoan jellyfish – the case study of Periphylla periphylla and Cyanea capillata
Jellyfish abundances have been reported to increase significantly in different aquatic ecosystems. Particularly in areas of rapid change such as the warming Arctic waters, jellyfish blooms might occur more frequently and cause problems for local fisheries. However, until today jellyfish remain an un...

Jellyfish abundances have been reported to increase significantly in different aquatic ecosystems. Particularly in areas of rapid change such as the warming Arctic waters, jellyfish blooms might occur more frequently and cause problems for local fisheries.
