Population size and structure of the common frog, Rana temporaria, have been intensively
studied by many authors during the last three decades (e.g. Cooke, 1975; Grossenbacher,
1980; Pascual andMontori, 1981; Hintermann,1984;Loman, 1984;Ryser, 1986;Elmberg,

Population size and structure of the common frog, Rana temporaria, have been intensively
studied by many authors during the last three decades (e.g. Cooke, 1975; Grossenbacher,
1980; Pascual andMontori, 1981; Hintermann,1984;Loman, 1984;Ryser, 1986;Elmberg,
1990; Kneitz, 1998). Most of these papers deal with low- or mid-altitude populations in
Central Europe, which are generally located in at least partly forested habitats,whereas few
studies have been carried out on the ecology of Rana temporaria in alpine environments
(e.g., Balcells, 1975; Elmberg and Lundberg, 1991; Ryser, 1996).
