These same taxa were also confirmed in the surrounding areas of the town. Twice as many amphibian species were found in areas affected to a lesser degree by urbanization than in heavily urbanized areas. Two groups of amphibians were distinguished, depending on their tolerance of urbanization at breeding ponds and surroundings: 1) species preferring only natural terrain or areas close to being natural - Bombina bombina, Pelobates fuscus and Rana arvalis; 2) taxa breeding in both natural areas as well as those under the pressure of urbanization - Tritunis cristatus, Tritunis vulgaris, Bufo bufo, Bufo viridis, Hyla arborea, Rana esculenta complex and Rana temporaria.}, type={Text}, title={Amphibians of Oława}, URL={http://rcin.org.pl/miiz/Content/36753/PDF/WA058_53132_P256-T53_Frag-Faun-Nr-2.pdf}, volume={53}, number={2}, journal={Fragmenta Faunistica}, publisher={Museum and Institute of Zoology, PAS}, keywords={anthropogenic pressure, ecology, Poland, urbanization, Amphibia, amphibians, Oława, urban animals, effect of human beings, man’s impact, populations}, }
