Indoor Event, 7pm.
Great North Museum, Newcastle.
Blue-green algae are the oldest known fossils, yet are still the main photosynthetic organisms of modern oceans. This talk covers a small part of their story, starting with interesting and sometimes very important occurrences around the world at present, and then going on to describe what you can see for yourself in northern England.
Brian Whitton is emeritus professor in Biological Sciences at Durham University. He has been fortunate enough to study blue-green algae in many parts of the world, but his main project started in the streams of Upper Teesdale, where the remarkable dominance by one alga demanded an explanation. Many years later he thinks he knows why.
