Physiological Responses of Cassiopea spp., to Selected Stress Factors
Cassiopea (upside-down jellyfish) is a key organism of the marine epibenthic community of the Gulf of Aqaba, where it plays important roles in nutrient cycling and fueling its habitat with released organic matters. The Gulf area is relatively small and has to suffer from an increasing number of anthropogenic activities, which are particularly harmful for the shallow coastal areas. In addition to pollution there is an increasing threat also through temperature rise, which causes oxidative stress responses in marine organisms. Therefore, a better understanding of Cassiopea responses to these stress factors would help to predict their performance under stress and therefore also their assumed indicator role in the Gulf of Aqaba, with implications for applicability also in other areas of the world.
