File S1 - Wetlands in Changed Landscapes: The Influence of Habitat Transformation on the Physico-Chemistry of Temporary Depression Wetlands

This file contains Appendix S1–S4. Appendix S1. Data for the candidate covariables incorporated into the analyses of this study. Time was incorporated as a quantitative covariable measured as days since first sampling event (‘date sampled’ is provided for general reference). dd - decimal degrees. Appendix S2. Ordinal scores for each type of land cover around wetlands used to proxy habitat transformation gradients. Natural – indigenous vegetation; Invaded – alien invasive vegetation; Agriculture – land converted to agriculture; Urban – land converted to urban surfaces. The areal cover of these categories was scored within 100 and 500 m radii of each wetland edge using an ordinal scale: 0 - none; 1 – sparse cover (66%). Appendix S3. Environmental variables measured in this study. CV – complex vegetation biotope; SV – simple vegetation biotope; OW – open water biotope; BU – benthic un-vegetated biotope; TSA – total surface area; Max. depth – maximum depth. Appendix S4. Summary statistics of the physico-chemical variables (untransformed data) collected in this study, reported per wetland cluster (defined by terrestrial vegetation group). EC – electrical conductivity. (DOCX)本文件包含附录S1至S4。 附录S1：本研究分析中纳入的候选协变量数据。时间以首次采样事件以来的天数为度量单位，作为定量协变量纳入分析（「采样日期」仅作为通用参考信息）。dd：十进制度（decimal degrees）。 附录S2：湿地周边各类土地覆盖类型的序数评分，用于作为生境转换梯度的替代指标。其中：自然植被类对应原生本土植被；入侵植被类对应外来入侵植被；农业用地类指转为农业生产用途的土地；城市用地类指转为城市建成环境的土地。上述各类别的面积占比以序数量表在每个湿地边缘100米和500米半径范围内进行评分：0代表无覆盖；1代表稀疏覆盖（占比66%）。 附录S3：本研究测定的环境变量。其中：CV为复合植被生境（complex vegetation biotope）；SV为简单植被生境（simple vegetation biotope）；OW为开阔水域生境（open water biotope）；BU为底栖无植被生境（benthic un-vegetated biotope）；TSA为总表面积（total surface area）；Max. depth为最大水深（maximum depth）。 附录S4：本研究收集的理化变量（未经过数据转换的原始数据）的汇总统计结果，按以陆生植被类群为划分依据的湿地集群分别报告。EC为电导率（electrical conductivity）。 (DOCX)
