Biological monitoring, from species to communities, is key to biodiversity conservation management, policy development and planning. Globally, amphibians are experiencing a major diversity crisis. In the case of Uruguay, there is a record of 49 species, 33% of which have been assigned to some category of threat. The objective of this work was to contribute to the generation of information on amphibian diversity through passive acoustic monitoring in the Alameda de San Carlos. During this study, 511 recordings were obtained, with a total of 2555 minutes of recording. A total of 14 amphibian species were recorded and identified. During the 22 days of sampling, temporal variation in the activity of recorded species was notorious. Boana pulchella and Scinax squalirostris were the only ones that were active during the entire sampling, while the rest of the species were active intermittently. This study represents the first work based on passive acoustic monitoring of anuran calls in our country, providing novel information that was not available for the study area and showing great potential for teaching activities in addition to scientific ones.Downloads
