metadata.value: Salinity is a crucial abiotic environmental factor for marine animals, affecting
  their physiology and geographic ranges. Deviation of environmental salinity
  from the organismal optimum range results in an osmotic stress in osmoconformers,
  which keep their fluids isotonic to the environment. The ability to
  overcome such stress is critical for animals inhabiting areas with considerable
  salinity variation, such as intertidal areas. In this study, we compared the reaction
  to mild water freshening (from 24 to 14 ‰) in two related species of intertidal
  snails, Littorina saxatilis and L. obtusata, with respect to several aspects:
  survival, behavior and proteomic changes. Among these species, L. saxatilis is
  more tolerant to low salinity and survives in estuaries. We found out that the
  response of these species was much milder (with no mortality or isolation reaction
  observed) and involved weaker proteomic changes than during acute
  stress (freshening from 24 to 10 ‰), characterized earlier. The proteomic response
  of the second species, L. obtusata, was weaker (6 % vs 10 % of regulated
  proteins) than that of L. saxatilis and engaged a mostly different set of proteins.
  Among proteins potentially involved in adaptation to low salinity, we identified
  enzymes of energetic metabolism and antioxidant response, chaperones, proteins
  of extracellular matrix and cytoskeleton, ion channels and regulators of
  cell growth and proliferation.
