Transition from Planktonic to Benthic Algal Dominance Along a Salinity Gradient

  title={Transition from Planktonic to Benthic Algal Dominance Along a Salinity Gradient},
  author={Richard D. Segal and Anya M Waite and David P. Hamilton},
Highly regulated salinity gradients in solar salt pond concentrating sequences provide an opportunity to investigate in situ salinity impacts on aquatic flora and fauna. The Shark Bay Salt solar ponds at Useless Inlet in Western Australia vary in salinity from seawater to four times seawater over the pond sequence. We observed a shift from planktonic to benthic primary productivity as salinity increased. Water column photosynthesis and biomass decreased markedly with increasing salinity, while… CONTINUE READING
