Variations of antioxidant efficiecy and presence of endosymbiotic diatoms in the Antarctic porifera Haliclona dancoi
The role of endosymbiotic diatoms as pro-oxidant stressors in porifera has been investigated in the Antarctic sponge Haliclona dancoi in which the presence of diatoms is influenced by marked seasonal variations during the austral summer. Both chlorophaeopigments and frustules were absent in sponge t...
