Original data for article: Acute and chronic response to a change in salinity of the euryhaline polychaete Pygospio elegans (Claparède)

subject

description

These data were collected in an experimental study designed to evaluate the ability of the polychaete Pygospio elegans to cope with an acute as well as a long-term change in salinity. Specimens from Herslev, Denmark, originating from a salinity of about 15 were exposed to salinity 15 as control and 5 and 30 as low and high salinity treatments. After acute exposure, we measured body volume changes as well as gene expression of seven genes related to volume- and osmoregulation within 4 hours of exposure.
