• Description:
  Effects of temperature rise (from 0 to +5°C) and salinity decline (from 34 to 30psu) on vital biological functions of the Antarctic isopod Serolis polita were studied in laboratory experiments. Behavioural reactions to food odour, as well as righting responses and reburying in the sediments, were measured. Both temperature increase and salinity decline impaired the ability of S. polita to perform these biological functions critical for their long-term survival, by lowering the number of isopods able to right and rebury in the sediment, increasing time-to-right, reducing locomotory activity and weakening isopod reaction to food odour. Significant interactive effects between temperature and salinity on time-to-right and time spent swimming were observed, with isopods being more vulnerable to lower salinities when exposed to higher temperatures. Some biological functions (righting, reburying) were more sensitive to temperature and salinity changes than others (swimming). In conclusion, our findings strongly suggest that Antarctic isopods are vulnerable to environmental changes, and their ability to cope with them is limited.
