"PROPeat_bryo_env_1911.csv" contains the environmental variables described in the paper "Bryophyte community composition and diversity are indicators of hydrochemical and ecological gradients in temperate kettle hole mires in Ohio, USA" (DOI: 10.19189/MaP.2019.APG.StA.1783). Please see the methods section for a detailed description of the data. transect_id: ID of the sampling location (transect) site: site code baseline: linear sampling baseline where transects are located transect: transect ID within each site date: date (YYY-MM-DD) when bryophytes were sampled wl_cm: average water level (cm) over the sampling period pH: average pH EC_microS: average electric conductivity (micro Siemens cm-1) wl_sd: standard deviation of the water level over the sampling period (cm) micro_sd: heterogeneity in microtopography as SD of 12 measures of distance from reference level to ground (cm) vasc_cover: cover of vascular plants (%) veg_type: broad vegetation type lat: latitude lon: longitude
