"Catchment productivity controls local species richness of hyporheic invertebrate communities in tropical New Caledonia streams"

This dataset allows to reproduce the statistical analysis whose results are presented in the article:"Catchment productivity controls local species richness of hyporheic invertebrate communities in tropical New Caledonia streams" In all tables, the 228 freshwater hyporheic sites are identified by a code ("Site_Code") and coordinates in decimal degrees WGS 84 ("X_long","Y_lat"). - File "Env_predictors_response_variables_Mouron_et_al_2025.csv" : main dataset with abundance, observed richness and estimated richness at a sample coverage level of 95% for total community, fast-growing species and slow-growing species, together with local and catchment predictors. The nine local predictors describe in-stream habitat conditions : dissolved oxygen ("DO", mg/L), redox potential ("Redox_potential", mV), pH ("pH"), specific conductance("Sp_conductance", µS/cm), temperature of hyporheic water ("Temperature", degree Celsius), mean annual air temperature ("Mean_annual_temp", degree Celsius), river width ("River_width", m), elevation ("Elevation", m), stream slope ("Stream_slope", m/m). The nine catchments predictors describe the entire upstream contributing catchment : catchment area ("Catchment_area", km2), areal proportion of peridotite ("Peridotite", %), normalized difference vegetation index ("NDVI"), three land cover predictors ("Landcover1", "Landcover2", "Landcover3"), mean annual precipitation ("Precipitation", mm/year), low flow specific discharge ("Discharge", L/s/km2), areal proportion of surfaces eroded by mining activities ("Mining"). Column headings for abundance and species richness data are as follows. “Abundance_Surf”: abundance of fast-growing species; “Abundance_GW”: abundance of slow-growing species; “Total_abundance”: total abundance; “Richness_Surf”: observed richness for the fast-growing species; “Richness_GW”: observed richness for the slow-growing species; “Total_Richness”: observed richness for the total community; “qD_Surf”: estimated richness (at a sample coverage level of 95%) for the fast-growing species; “qD_Surf_rd”: rounded value of estimated richness for the fast-growing species; “qD_GW”: estimated richness for the slow-growing species; “qD_GW_rd”: rounded value of estimated richness for the slow-growing species; “qD_Tot”: estimated richness for the total community; “qD_Tot_rd”: rounded value of estimated richness for the total community. - File "Sample_species_data_Mouron_et_al_2025.csv": species per site data. OTU: operational taxonomic unit; MOTU: molecular operational taxonomic unit.本数据集可复现发表于论文《新喀里多尼亚热带溪流中集水区生产力调控渗流带无脊椎动物群落的本地物种丰富度》（Catchment productivity controls local species richness of hyporheic invertebrate communities in tropical New Caledonia streams）的统计分析及其研究结果。 所有表格中，228个淡水渗流带采样点均通过站点代码（"Site_Code"）及采用世界大地测量系统1984（World Geodetic System 1984, WGS 84）的十进制度坐标（"X_long"、"Y_lat"）进行标识。 - 文件 "Env_predictors_response_variables_Mouron_et_al_2025.csv"：主数据集，包含总群落、速生类群与慢生类群在95%样本覆盖度下的丰度、观测物种丰富度及估计物种丰富度，同时附带本地及集水区尺度的预测变量。 9个本地预测变量描述溪流内生境条件：溶解氧（DO, mg/L）、氧化还原电位（Redox_potential, mV）、pH值（pH）、比电导率（Sp_conductance, µS/cm）、渗流水体温度（Temperature, 摄氏度）、年平均气温（Mean_annual_temp, 摄氏度）、河宽（River_width, m）、海拔（Elevation, m）、溪流坡度（Stream_slope, m/m）。 9个集水区预测变量表征整个上游汇水集水区：集水区面积（Catchment_area, km²）、橄榄岩占比（Peridotite, %）、归一化差分植被指数（NDVI, Normalized Difference Vegetation Index）、3个土地覆盖预测变量（Landcover1、Landcover2、Landcover3）、年平均降水量（Precipitation, mm/年）、低流量比流量（Discharge, L/s/km²）、采矿活动侵蚀地表占比（Mining）。 丰度及物种丰富度数据的列标题如下： "Abundance_Surf"：速生类群丰度；"Abundance_GW"：慢生类群丰度；"Total_abundance"：总丰度；"Richness_Surf"：速生类群观测物种丰富度；"Richness_GW"：慢生类群观测物种丰富度；"Total_Richness"：总群落观测物种丰富度；"qD_Surf"：速生类群在95%样本覆盖度下的估计物种丰富度；"qD_Surf_rd"：速生类群估计物种丰富度的取整值；"qD_GW"：慢生类群估计物种丰富度；"qD_GW_rd"：慢生类群估计物种丰富度的取整值；"qD_Tot"：总群落估计物种丰富度；"qD_Tot_rd"：总群落估计物种丰富度的取整值。 - 文件 "Sample_species_data_Mouron_et_al_2025.csv"：单站点物种数据文件。OTU（operational taxonomic unit，操作分类单元）；MOTU（molecular operational taxonomic unit，分子操作分类单元）。
