Population, ecology and genetic characteristics of the Mediterrannean box jellyfish Carybdea Marsupialis in the island of Malta

Trabajo presentado en el 41st CIESM Congress, celebrado en Kiel del 12 al 16 de septiembre de 2016.
The main aims of this study were to investigate the environmental parameters associated with blooming events of Carybdea marsupialis and to genetically compare the box jellyfish in Malta to other Mediterranean and Atlantic samples. The numbers of adult individuals, as well as abiotic and biotic factors were monitored in situ and analysed statistically. Phenological patterns were determined and the abundance of C. marsupialis at the Maltese sites was shown to be strongly and positively correlated with sea water temperature. Genetic analysis indicated a high degree of homology between the sequences derived from the analysed Mediterranean specimens, which was not apparent in the genetic material derived from specimens from the Eastern Atlantic (Cadiz).
