Abhandlung

The inception of Tetraonid research in the Swiss Alps. – Unable to study Tetraonids myself due to other commitments, I was lucky enough to be able to propose continued study of my projects to some extremely engaged students who were happy to continue the work which we had begun in the 1960’s, even after their promotion, enabling the work to carry on for almost 45 years. As I knew the Aletsch region (canton of Valais, Switzerland) well since my early childhood, we concentrated our research work there, always ensuring that we compared the results with populations in other parts of the Swiss Alps. The results of the long term studies were of great value because they demonstrated how erroneous the conclusions of short term findings could be. After such a long period of study, we claim to have a good insight, particularly into the ecology of the Black Grouse Tetrao tetrix and the Rock Ptarmigan Lagopus muta. Despite this, it appears difficult to judge what kind of environmental changes and influences (habitat deterioration and increasing distur­bances) are in fact, the most decisive for dislocations of Grouse leks and Ptarmigan territories as well as demographic fluctuations.
