AbstractLiving conditions for plants in the mountains become increasingly less favorable with increasing altitude. As a result the number of plants which are adapted to these conditions and able to s~rvive decreases. This is a principal reason why the vegetation in the mountains is often clearly segmented into altitudinal levels or zones. While floristlc investigation of these levels, their naming, and the first attempt to discover their climatic causes extends back into the eighteenth century, organized research into the relationship of alpine plants to their environment was first initiated at the turn of the last century. The pioneering work in this field was particularly that of Bonnier (1) and Senn and his students (2) at the alpine laboratory at 2356 m on Muottas Muraigl near Pontresina, Switzerland. In 1926, Schr~ter (3) summarized the results of these and other early investigations and outlined an extremely fascinating picture of the life and struggles of alpine plants. With progressive improvement and development of methods for the measurement of the life functions of plants in the field and of the climate in their immediate vicinity (the microclimate), knowledge about the physiology and ecology of alpine plants has become substantially enlarged and deepened. Particularly the investigations of the Botanical Institute of the University at Innsbruck, which have been carried out during the last 30 years under the leadership of Professor A. Pisek, have contributed to this field. We also have Professor Pisek to thank for the last descriptive summary of the life of alpine plants (4, 5) as well as a review on photosynthesis at high altitudes (6). The following review is limited to those sections of alpine plant physiology which have been most extensively studied.
