Metadata for raw data used for analyses in: T. M. Swartz and J. R. Miller. 2019. Managing farm ponds as breeding sites for amphibians: key trade-offs in agricultural function and habitat conservation. Ecological Applications.Files:1. DataS1_unmarkedAnalyses.csv2. DataS2_Chronosequence_Analysis.csvDescriptions:File 1: DataS1_unmarkedAnalyses.csv • contains all data used to perform the single season ocucpancy analyses described in the manuscript: Swartz and Miller (2019) Managing farm ponds • PondID: represents the coded name given to each pond (site)• Amphibian species: names are abbreviated as follows:  HYLA: Hyla chrysoscelis/versicolor (Cope's/Eastern gray treefrog)  ACBL: Acris blanchardi (Blanchard's cricket frog)  LIBL: Lithobates blairi (Plains leopard frog)  LICA: Lithobates catesbeianus (American bullfrog) o In all cases, the year being analyzed is denoted as either "16" or "17", and the number of sites included is denoted with "51" o For each species, there are 8 columns containing a "1", "0", or "NA", to signify whether the species was present, absent, or no surveys were performed during the 8 sampling occasions (four in each year). o The sampling occasions are denoted as the 3rd number in the column headings for the amphibian species.• Habitat variables, the following abbreviations are used in the column headings: o FL= Floating vegetation percent cover o EM= Emergent vegetation percent cover o AQ= submerged/aquatic vegetation percent cover o LogArea= log-transformed area of each pond (in meteres^2) o cattle= presence or absence of cattle around the pond o Fish= presence or absence of fish in the pond• Detection Covariates: o Columns containing "J", "Temp", or "T", represent Julian date, Mean daily temperature, or sampling occasion number, respectively, followed by the year ("16" or "17", where applicable) and the sampling occasion number. File 2: DataS2_Chronosequence_Analysis.csv• contains all data used to perform the chronosequence analyses described in the manuscript. o PondID: represents the coded name given to each pond (site)• Habitat variables, the following abbreviations are used in the column headings:  FL= Floating vegetation percent cover  EM= Emergent vegetation percent cover  AQ= submerged/aquatic vegetation percent cover  LogArea= log-transformed area of each pond (in meteres^2)  cattle= presence or absence of cattle around the pond o For each variable, the year of the measurement was taken is noted as either a "1617" to indicate that measurements from 2016 and 2017 were averaged for this comparison. pH, was only measured in 2017 so no year is listed.
