Abstract The degradation of freshwater ecosystems due to land use changes is one the major driver global biodiversity loss and amphibian declines with these impacts varying across different spatial scales. Our study aimed assess how natural human-modified affects smooth newt ( Lissotriton vulgaris ) abundance in surrounding waterbodies Lake Balaton, a highly urbanized area. We conducted aquatic trap surveys at 32 wetland sites during breeding season quantified cover within 250, 500, 1000-m radius buffer zones. hypothesized that urban use, cropland, proximity roads railways would negatively correlate abundance, while wetlands areas (marshes, swamps, periodically flooded grasslands) terrestrial habitats (grasslands, forests woodlands) positively correlate, effects N-mixture models were used analyse survey data, estimating examining relationships covariates. Results revealed 500-m zone increased probably supporting metapopulation connectivity. In contrast, cropland 250 m affected abundance. Conservation efforts should prioritize providing newts adequate reducing disturbances from croplands, roads, railways.
