Fig. 8. Succinate levels in Geukensia demissa gills (filled columns) and Mytilus edulis gills (hatched columns) under aerated conditions (Air), aerated conditions with 100 µmol l^-1 Na₂S added at time zero (Air+Na₂S) and anaerobic conditions produced by nitrogen gas (N₂), all for 10 min. Values are means ± S.D. (N=3). Asterisks designate a significant difference from the value under aerated conditions; double daggers designate a significant difference from the value under aerated conditions with 100 µmol l^-1 Na₂S. (A) Gills exposed to 0.5 µmol l^-1 5-HT. (B) Gills exposed to 10 µmol l^-1 5-HT.
