Differing long term trends for two common amphibian species (Bufo bufo and Rana temporaria) in alpine landscapes of Salzburg, Austria

A two-decade study of amphibian populations along roadsides in Salzburg, Austria, reveals starkly contrasting trends for the common toad (Bufo bufo) and the common frog (Rana temporaria). While the common toad population remains stable, the common frog has experienced a significant decline, particularly in alpine regions. This decline is attributed to habitat destruction driven by drainage and agricultural intensification, which disproportionately impacts the micro-climate and spawning habitats of the common frog. The study highlights the severe ecological consequences of such losses for widespread species, often overlooked in conservation efforts.
