Anuran detectability and calling phenology in urban ponds from the Brazilian Savanna
Over the last century, urban development has steadily resulted in wetland destruction, stream flow disturbance, and land clearing. Small intermittent wetlands are easily overlooked in large cities, and the secretive nature of amphibian species in these habitats can hinder see the big picture about t...

Small intermittent wetlands are easily overlooked in large cities, and the secretive nature of amphibian species in these habitats can hinder see the big picture about the persistence of populations in urban habitats. Here, we determined anuran detectability associated with site-specific and survey-specific variables. We also identified the reproductive modes and described the calling activity along a four-year period in urban ponds of the Brazilian Cerrado ecoregion. We recorded 16 anuran species, but only nine were detected at levels suitable for modeling. Seven reproductive modes were observed in the assemblages, and although breeding choruses were more common in the rainy season, calling activity was also recorded in the dry season for 11 species. Anuran detectability was related to pond water depth, rainfall for the previous 24h, and day-of-year. Our results showed interplay between species-specific traits and water availability. We highlight that urban ponds can harbor a considerable proportion of anuran diversity; however, urbanization seems to constraint even generalist species recorded for the Cerrado ecoregion. Ao longo do último século, o desenvolvimento urbano resultou constantemente na destruição de áreas úmidas, alteração do curso de riachos e desmatamento. Pequenas áreas úmidas intermitentes são facilmente ignoradas nas grandes cidades, e a natureza inconspícua das espécies de anfíbios nestes habitats pode esconder o quadro geral sobre a persistência das populações em ambientes urbanos. Aqui, determinamos a detectabilidade de anuros associada a variáveis específicas do local e da amostragem. Nós também identificamos a diversidade de modos reprodutivos e atividade de vocalização ao longo de um período de quatro anos em lagoas urbanas do Cerrado. Registramos 16 espécies de anuros, mas apenas nove foram detectadas em níveis adequados para a modelagem. Sete modos reprodutivos foram observados nas assembleias e, embora coros reprodutivos tenham sido mais comuns na estação chuvosa, a atividade de vocalização também foi registrada na estação seca para 11 espécies. A detectabilidade de anuros foi relacionada à profundidade da água, precipitação nas 24h anteriores e dia do ano. Nossos resultados mostraram uma interação entre traços específicos das espécies e a disponibilidade hídrica. Destacamos que as lagoas urbanas podem abrigar uma porção considerável da diversidade de anuros. Entretanto, a urbanização parece restringir até mesmo espécies generalistas registradas para a ecorregião do Cerrado.
