Abstract

STONER, Elizabeth W.; SEBILIAN, Serina S.  and  LAYMAN, Craig A.. Comparison of zooxanthellae densities from upside-down jellyfish, Cassiopea xamachana, across coastal habitats of The Bahamas. Rev. biol. mar. oceanogr. [online]. 2016, vol.51, n.1, pp.203-208. ISSN 0718-1957.  http://dx.doi.org/10.4067/S0718-19572016000100022.

Anthropogenic disturbances may drive jellyfish blooms, and previous studies have suggested this is the case for upside-down jellyfish (Cassiopea xamachana). Cassiopea were found to have higher mean zooxanthellae densities in human-impacted areas on Abaco Island, The Bahamas, suggesting that nutrient loading in impacted sites may be one factor driving zooxanthellate jellyfish blooms. Gut contents from Cassiopea medusae were positively correlated to zooxanthellae densities, indicating that heterotrophically-derived nutrition may be an important factor in facilitating increased zooxanthellae population densities. Understanding the mechanisms driving jellyfish blooms is crucial for developing effective management strategies in impacted coastal ecosystems.

Keywords : Benthic; facilitation; human impacts; heterotrophy; mutualism.
