Unique and shared effects of local and catchment predictors over distribution of hyporheic organisms: does the valley rule the stream?

This dataset allows to reproduce the statistical analysis whose results are presented in the article:"Unique and shared effects of local and catchment predictors over distribution of hyporheic organisms: does the valley rule the stream? ", Mouron et al. 2022, Ecography (https://doi.org/10.1111/ecog.06099) This analysis can be reproduced using the script submitted to Zenodo at https://doi.org/10.5281/zenodo.6104368 - "Mouron_et_al_2022_Landcover.csv" : Landcover data from GIS analysis to perform correspondence analysis (see script).Variables : "Bare soil","Herbaceous","Shrubs","Mature forest","Urban","Water" ; i.e. the land cover composition for the 228 catchments (see Supplementary material Appendix 1, Fig. A1).- "Mouron_et_al_2022_data.csv" : main dataset that contain occurences of Bogidiellids and Anthurids, local predictors and catchment predictors for 228 sites. The 228 freshwater hyporheic sites are identified by a code ("Site_Code") and coordinates in WGS 84 ("X_long","Y_lat").Occurences ("Bogi","Anthu") are presence/absence data for subterranean crustaceans Bogidiellidae and Anthuridae sampled in November 2016, November 2017 and July 2018. The nine local predictors describe in-stream habitat conditions : river width ("River_width", m), specific conductance("Sp_conductance", µS/cm), dissolved oxygen ("DO", mg/L), redox potential ("Redox_potential", mV), pH ("pH"), temperature of hyporheic water ("Temperature", °C), mean annual air temperature ("Mean_annual_temp", °C), elevation ("Elevation", m) and stream slope ("Stream_slope", m/m).The eight catchments predictors describe the entire upstream contributing catchment : catchment area ("Catchment_area", km2), areal proportion of peridotite ("Peridotite", %), three land cover predictors ("Landcover1","Landcover2","Landcover3"), normalized difference vegetation index ("NDVI"), mean annual precipitation ("Precipitation", mm/year) and low flow specific discharge ("Discharge", L/s/km2).

"Mouron_et_al_2022_Landcover.csv"：用于开展对应分析（correspondence analysis）的地理信息系统（Geographic Information System，GIS）土地覆被数据（详见配套脚本）。变量包括：裸土（Bare soil）、草本植被（Herbaceous）、灌丛（Shrubs）、成熟林（Mature forest）、城镇用地（Urban）、水体（Water），即228个集水区的土地覆被组成信息（详见补充材料附录1图A1）。

"Mouron_et_al_2022_data.csv"：核心数据集，包含228个淡水渗流带站点的Bogidiellidae（蜾蠃蜚科）与Anthuridae（突角水虱科）物种数据、局地预测变量及集水区预测变量。该228个淡水渗流带站点通过"Site_Code"字段标识，坐标采用WGS 84坐标系，对应字段为"X_long"（经度）与"Y_lat"（纬度）。
其中，"Bogi"与"Anthu"为2016年11月、2017年11月及2018年7月采样得到的地下甲壳动物Bogidiellidae与Anthuridae的存在/缺失数据。
九项局地预测变量用于描述河道生境条件：河道宽度（River_width，单位：m）、比电导率（Sp_conductance，单位：µS/cm）、溶解氧（DO，单位：mg/L）、氧化还原电位（Redox_potential，单位：mV）、pH值、渗流水体温度（Temperature，单位：°C）、年平均气温（Mean_annual_temp，单位：°C）、海拔（Elevation，单位：m）与河道坡度（Stream_slope，单位：m/m）。
八项集水区预测变量用于描述完整上游汇水流域：集水区面积（Catchment_area，单位：km²）、橄榄岩占比（Peridotite，单位：%）、三项土地覆被预测变量（Landcover1、Landcover2、Landcover3）、归一化差异植被指数（Normalized Difference Vegetation Index，NDVI）、年平均降水量（Precipitation，单位：mm/年）与低流量比流量（Discharge，单位：L/s/km²）。
