Image of the Day: Saltwater Survivors

When road deicing salt enters freshwater ecosystems, prey species such as Daphnia pulex can rapidly evolve tolerance to the contaminant, buffering their local food webs from the impacts of salination.

It appears this was not a controlled experiment in that the exposure conditions before and after "evolution" were not the same.  It may be that the physiological responses to certain salinity were always there, so attribution to rapid evolution may be a stretch.
