Oxygen exchange and nutrient transformation rates under fluctuating salinity treatments in two subtidal marsh habitats
Farris CN. 1996. Oxygen exchange and nutrient transformation rates under fluctuating salinity treatments in two subtidal marsh habitats. University of Rhode Island
From the abstract: "This research investigated oxygen exchange and nutrient regeneration processes in two subtidal salt marsh habitats. I investigated the changes in exchange rates that the two environments exhibited in response to a change in salinity of the overlying water over a tidal cycle. This was done in order to examine how these habits respond to environmental variability. Oxygen production in both the sediment and macroalgal habitats increased with increasing salinity, demonstrating an inhibition of productivity during low salinity levels. Macroalgal production rates also exhibited peak levels in early July and were associated with salinity, light levels and high levels of algal biomass. Macroalgal respiration rates were associated with temperature and algal biomass levels. Sediment production and respiration rates were much smaller than macroalgal rates, but showed similar trends."
