“…Regarding medusae populations, it is noted that originally, the Mar Menor had a native population of Aurelia aurita L. (Franco and Gili 1989). However, since the mid 1980s, other species of cnidarians, most notably Cotylorhiza tuberculata, entered the lagoon from the Mediterranean, reaching to close its life's cycle in this lagoon.…”

“…As a consequence, several species of jellyfish began to be observed in this coastal lagoon, hitherto not mentioned in this lagoon's ecosystem. Among these species stands out the scyphozoan Cotylorhiza tuberculata (Macri 1778) that due to the new temperature and salinity conditions of the Mar Menor was able to close his life cycle within the lagoon (Fuentes et al 2011). A decade later, the proliferations of jellyfish were initiated in response to increased flow of nutrients and eutrophication of the lagoon ( Pérez-Ruzafa et al 2002), being captured in 2012, after 26 days of fishing at sea, the amount of 3,938,233 individuals of C. tuberculata in this lagoon (CARM 2013).…”

Coastal lagoons are ecosystems highly vulnerable to human impacts because of their situation between terrestrial and marine environment. Mar Menor coastal lagoon is one of the largest lagoons of the Mediterranean Sea, placed in SE Spain and subjected to major human impacts, in particular the mining of metal sulphides. As a consequence, metal concentration in water column and sediments of this ecosystem is usually higher than in other areas. For monitoring ecosystem health, the present study has assessed the ability of Cotylorhiza tuberculata for bioaccumulating metals from sea water. Up to 65 individuals were sampled at 8 different sampling stations during the summer of 2012. Although the concentration values for different elements considered were moderate (Pb: 0.04-29.50 ppm, Zn: 2.27-93.44 ppm, Cd: 0-0.67 ppm, As: 0.56-130.31 ppm) by dry weight of the jellyfish tissues (bell and oral arms combined), bioconcentration levels in relation to seawater metal concentration were extremely high. In any case, the use or disposal of these organisms should consider their metal content because of their potential environmental and health implications.

Reports of nuisance jellyfish blooms have increased worldwide during the last half-century, but the possible causes remain unclear. A persistent difficulty lies in identifying whether blooms occur owing to local or regional processes. This issue can be resolved, in part, by establishing the geographical scales of connectivity among locations, which may be addressed using genetic analyses and oceanographic modelling. We used landscape genetics and Lagrangian modelling of oceanographic dispersal to explore patterns of connectivity in the scyphozoan jellyfish Rhizostoma octopus , which occurs en masse at locations in the Irish Sea and northeastern Atlantic. We found significant genetic structure distinguishing three populations, with both consistencies and inconsistencies with prevailing physical oceanographic patterns. Our analyses identify locations where blooms occur in apparently geographically isolated populations, locations where blooms may be the source or result of migrants, and a location where blooms do not occur consistently and jellyfish are mostly immigrant. Our interdisciplinary approach thus provides a means to ascertain the geographical origins of jellyfish in outbreaks, which may have wide utility as increased international efforts investigate jellyfish blooms.

“…Scyphozoans and hydrozoans have especially versatile reproductive strategies (Lucas, 2001;Boero et al, 2002;Fuentes et al, 2011). This versatility may predispose them to exploit changing conditions that may prove detrimental to other taxa.…”

In recent decades, many areas worldwide have experienced mass occurrences of jellyfish.To determine how temperature may affect jellyfish populations in the northwest (NW) Mediterranean Sea, we maintained polyps of three scyphozoan species, Aurelia aurita, Rhizostoma pulmo, and Cotylorhiza tuberculata in the laboratory at three temperatures (14, 21, 28°C) to test effects on survival and production of new polyps and ephyrae. Temperature significantly affected survival of all species, with longest survival of A. aurita and R. pulmo at 14°C and of C. tuberculata at 21°C. More polyps were budded by all species at temperatures above 14°C. A. aurita produced the most buds polyp -1 (43.5) and R. pulmo the fewest (8.8). Strobilation occurred only at 14°C for A. aurita and at 21°C for C. tuberculata. For R. pulmo, fewer polyps strobilated and strobilated later at 14°C. These patterns of survival and asexual reproduction were seasonally appropriate for each species in the NW Mediterranean, where A. aurita medusae occur earliest (*April-May) in cool waters, followed by R. pulmo during May-June, and then by C. tuberculata in mid-summer. Comparisons among scyphozoan species suggested that many may be restricted by low temperatures, and that global warming may benefit temperate species, but not tropical or boreal species.
