Data from: Delayed breeding phenology of low-latitude frogs over 15 years revealed by passive acoustic monitoring

Data from: Delayed breeding phenology of low-latitude frogs over 15 years revealed by passive acoustic monitoring This data contains the number of call detections of seven frog species and climate data from Iriomote Island, Japan, during 2009–2025, and R scripts to replicate our analyses. Descriptions data detection: Daily detection counts inferred from the custom-trained BirdNET model. medianl-calling-date: Lists of median calling dates for each species at each site. The “median_calling_date” column shows calendar dates. The “num_median_calling_date” column shows the same dates converted to numerical values: days since 1 January for summer breeders and days since 1 June for autumn–spring breeders. These numerical values were used in the regression analyses. randomization-dataset: RDATA files containing the results of randomization analyses conducted using the climwin package. Itiomore-weather.csv: Climate data originally downloaded from the Japan Meteorological Agency website (https://www.data.jma.go.jp/risk/obsdl/index.php) R scripts: R code used for statistical analyses and figure generation in the manuscript. Abbreviations I use abbreviations for species scientific name in the file names and in the script.
