 abstract={The study on the occurrence of amphibians in the city of Słupsk (NW Poland) was conducted during their breeding season in 40 water bodies located in a built-up area, at a forest edge, and in a ruderal area of the city. Breeding amphibians were recorded from 27 water bodies, or 67.5% of them. The number of amphibian species varied between 0 and 7, with an average of 2.2, depending on the location and the degree of modification of the water bodies. The average number of breeding species was 1.2 in the built-up area, 2.8 at the forest edge, and 2.3 in the ruderal areas. Breeding amphibians avoided human- modified water bodies, where only 0.6 species were noted as compared with 2.6 species in natural ones. In total, 9 species of amphibians were recorded from Słupsk. The most frequently observed were the common frog and the common toad, less frequently green frogs, the smooth newt, and the moor frog. Infrequentlyoccurred: the common spadefoot, the natterjack toad the fire-bellied toad.},
