Abstract

The author discusses possible effects of global warming on distribution and ecology of larger fungi, and presents examples of suggested indicator species which apparently are spreading from south to north. Only Basidiomycetes are corncerned, while actually no case of non-lichenized Ascomycetes is known. A continued monitoring of the mentioned species is recommended.

Highlights

  • Global warming with its consequences for weather and local climate, rising sea level, retreat of glaciers and of polar ice calottes, and subsequent nature catastrophes, is much disputed in newspapers, journals, and book publications

  • This is not the place to discuss whether or not it is possible to conserve the mycoflora of a given territory in its actual composition and status, but we should be aware that we are living on a planet which is in permanent evolution since thousands millions of years, and will continue to evolve

  • Since about 15 000 years, large areas in northern Germany and northern Poland, which had been covered by inland ice during the last (Weichsel) glaciation of pleistocene, have been reoccupied by vegetation and by mycoflora - insomuch every species of Fungi which we observe in these areas, has reacted to a long-term global warming

Summary

INTRODUCTION

Global warming (climatic change) with its consequences for weather and local climate, rising sea level, retreat of glaciers and of polar ice calottes, and subsequent nature catastrophes, is much disputed in newspapers, journals, and book publications. Since the end of last Ice Age, some 15 000 years ago, climate in central and northern Europe is warming, and enormous ice calottes have retired from this region, making possible a re-settelement of large areas by vegetation and fauna. This process was not continuous, but interrupted by phases of standstill alternating with phases of further warming. Attention of mycologists was concentrated on processes of threat and decline of mycoflora by presumably man-made factors, with subsequent publication of a rich literature of Red Data Lists and evaluations of long registers of species regarded as endangered in different degrees
