Population dynamics and relationship with environmental conditions of three scyphozoan jellyfishes in the Mar Menor lagoon (Spain)

Blooms of jellyfishes are perceived to have increased during the last decades causing interference with human activities of both recreational and professional type. Those blooms seem to hold correlation with human impacts and climate change parameters such as overfishing, the increase of temperature, eutrophication and habitat modification. In this study we perform the first simultaneous analysis population dynamics of three scyphozoan jellyfishes, Cotylorhiza tuberculata (Macri, 1778), Aurelia sp. and Rhizostoma pulmo (Macri, 1778). Moreover, the effect of the nutrient input, temperature, salinity, ichthyoplankton and chlorophyll a have been studied for the three species. Temperature and its seasonal cycle have been determined to be a key factors regulating the populations, triggering the strobilation process either by an increase of temperature (C. tuberculata) or by a decrease of it (Aurelia sp.) and indicating that not all the species of jellyfish may be benefited from the climate change
