"Karst and Cryokarst", dedicated to the memory of Teresa Wiszniowska (authority on research of large fossil mammals, cave bear especially) and Marian Pulina (authority on speleology and geomorphology), contains works covering the subjects of their broad scientific interests. The book is a joint publication of Karst Commission of the International Geographical Union (IGU) and Commission Glacier Caves and Cryokarst in Polar and High Mountain Regions /GLACKIPR/ of the International Union of Speleology (UIS).
Both Professors started their scientific and teaching career at the Faculty of Natural Sciences of the University of Wrocław, as well as caving and speleological activity in Sudetes. After discovery of the Jaskinia Niedźwiedzia (Bear Cave) in Kletno (Western Sudetes), they were performing multidisciplinary studies of the cave environment for many years. They resulted in creation of multidisciplinary and international Speleological School, which has been organized in the winter since 1975. At the beginning, the University of Wrocław and later University of Silesia were the main organizer of the School. The 25th edition of Speleological School held in March 2007 in Sosnowiec and Wrocław.
