Physiological flexibility; a necessity for life in anoxic and sulphidic habitats

Shallow marine areas and brackish water are often characterized by extensive short- or long-term fluctuations in physical parameters: temperature, salinity, oxygen. Sulphide can accumulate as a consequence of oxygen deficiency. Diel fluctuations in oxygen can in non-exposed shallow waters vary from 0 to 300% saturation, at the same time temperature can… CONTINUE READING
