Measuring Selection in Natural Populations

The present volume constitutes the proceedings of the~ymposium: "Measur­ ing Selection in Natural Populations", held in memory of late professor Ove Frydenberg. The Symposium took place in Sandbjerg Manor House in Southern Jutland May 10-14, 1976. The purpose of the symposium was to reflect contemporary research on the mechanisms of biological evolu­ tion. The arrangement of the symposium was possible only with the assis­ tance and work of many other people. Professor Ole Barndorff-Nielsen took an active part in the planning and arrangement of the symposium. Our gratitude is also due to Ellen Christensen, Jens Ole Frier, Arno Jensen, Preben Jensen and Anne Nissen, all of whom took care of the practical arrangements at the symposium. The publication was prepared with the assistance of Arno Jensen, Preben Jensen, Verner Blak Nielsen and Kirsten Svendsen. The Symposium was financed by grants from The Danish Natural Science Research Council, The Danish Atomic Energy Commission and The University of Aarhus. Aarhus, June 1977 Freddy B.
