ReadMe_file.txt information woodfrogdata.csv This is the main data file with all years of data from all ponds. This dataset contains 14 columns x 1130 rows Pond.ID = pond name Year = year of data collection Depth = depth (cm) of water within a pond during egg mass surveys at depth gauge or in deepest point of pond (if no gauge is installed) RASY.Count.1 = independent whole pond count of Rana sylvatica egg masses by observer 1 RASY.Count.2 = independent whole pond count of Rana sylvatica egg masses by observer 2 Avg.RASY.Count = average of the two independent counts RASYdens = density of RASY egg masses (Avg.RASY.Count/pond area) in egg masses/m2 GrowthRate = population growth rate as estimated by egg masses (see explanation above) RASYdens_t2 = RASY density two years prior to the current year (egg masses/m2) days_thawed = number of days between 1 October and 30 March above freezing in the winter prior to breeding spfaPDSI = average monthly drought severity value from 1 March to 30 September of the breeding year spfaPDSIlag = average monthly drought severity value from 1 March to 30 September two years prior to the breeding year wEggs = number of egg masses in neighboring ponds within 500 m of focal pond weighted by distance from pond (see data description) distance.mat.csv Distance matrix for distance (in meters) between each pond. Dataset is 65 columns x 65 rows. pondinfo.csv Area (m2) and canopy data (as Global Site Factor, see data description) for each pond. Dataset is 3 columns x 65 rows.
