The book "Limnology of Mountain Lakes" offers a comprehensive collection of research papers presented at the international symposium on the limnology of mountain lakes. This symposium took place from July 1 to 7, 1991, in Stará Lesná, Slovakia. The contributions cover a wide range of topics, including physical and chemical limnology, paleolimnology, as well as the study of zooplankton, phytoplankton, phytobenthos, and bacteria. A central theme is acidification, which affects the water chemistry and biota of many mountain lakes in Europe. Special emphasis is placed on the lakes in the Bohemian Forest, which are in the final stages of acidification, as well as extensive studies on the Tatra and Alpine regions. This collection is a valuable resource for scientists and students dealing with the limnology and ecological challenges of mountain lakes.
