Talk: "More bird species in the world – how is that possible?" with Per Alström

More than 100 bird species have become extinct since 1800. Only a few new species are discovered annually. Yet the number of bird species in the world increases! How can that be? The answer is that modern technology, such as DNA- and sound analysis, has revealed that many forms previously classified as sub-species are so distinct that they should instead be classified as an individual species. Many of these “new” species have limited range and small populations and are probably threatened. Per Alström, a well-known and much appreciated guest in this year’s lecture programme, clarifies a lot of what science knows and will undoubtedly talk about what science doesn’t know – yet!
