Reviving 100-year-old resting spores of diatoms
Date:3/1/2011

resting spores when the eutrophication was at its worst and the freshest ones of all, but the individuals are for the most part very homogeneous throughout the sediment core, that's to say 40 000 generations of diatoms."

No traces of genetic impact over 100 years

"The most exciting thing of all in the whole study is that there are no traces at all of genetic impact from the open sea population on the diatoms in Mariager Fjord during the 100 years we have studied, despite a constant influx of diatoms from the Kattegatt with the surface water. Not one out of all the millions upon millions of diatoms that have found their way into the fjord from the Kattegatt has become established and continued to grow in the fjord.

The researchers believe that this is due to the fact that the algae that live inside the fjord are so superbly well adapted to the fjord environment and that there are so many of them (millions per litre of water, thousands per gram of sediment) that colonisers from outside are rapidly out-competed.
