Summary

This study on solar salterns reveals that increasing salinity reduces eukaryotic microbes but boosts prokaryotic biomass. Microbial activity peaked around 100 PSU, with bacterivory ceasing above 250 PSU.

Area of Science:

  • Microbial ecology
  • Aquatic microbiology
  • Saltern ecosystems

Background:

  • Solar salterns offer unique, complex ecosystems along salinity gradients.
  • Understanding microbial food web dynamics is crucial in hypersaline environments.

Purpose of the Study:

  • To investigate the impact of salinity on microbial food web structure and function in solar salterns.
  • To determine how prokaryotic and eukaryotic microbial groups respond to increasing salt concentrations.

Main Methods:

  • Sampling across a salinity gradient in two commercial solar salterns.
  • Quantification of prokaryotes, phytoplankton, and zooplankton (flagellates, ciliates).
  • Measurement of prokaryotic heterotrophic production and chlorophyll a concentration.

Main Results:

  • Increasing salinity led to decreased abundance of eukaryotic microorganisms.
  • Prokaryotic biomass increased with salinity, with maximal activity around 100 PSU.
  • Bacterivory was eliminated at salinities above 250 PSU.

Conclusions:

  • Salinity is a key driver structuring microbial communities in solar salterns.
  • Prokaryotes dominate hypersaline environments, while eukaryotes are suppressed.
  • Peak microbial productivity occurs at intermediate salinities (around 100 PSU).
