Global Crayfish Database of Geospatial Traits

This dataset provides a global, network-aware environmental trait database for freshwater crayfish (Decapoda: Astacidea). It integrates 115,191 georeferenced occurrence records from the World of Crayfish® (WoC®) platform with approximately 400 environmental variables extracted through the GeoFRESH framework, using the Hydrography90m river network at 90 m resolution. Environmental variables span climate, topography, soil, and land cover at both local (segment-level) and upstream (catchment-aggregated) scales. Following quality filtering, 65,957 records across 273 taxa from all three extant families (Astacidae, Cambaridae, Parastacidae) were retained for species-level statistical synthesis, yielding over 8,000 data points per taxon. Geographic coordinates are withheld under the WoC® community data protocol for species protection. Full methodological details are provided in the accompanying manuscript: Petko et al., "Network-aware environmental trait database for global freshwater crayfish", Scientific Data (submitted).本数据集构建了一套全球适配河网维度的淡水螯虾（Decapoda: Astacidea，十足目：螯虾下目）环境性状数据库。其整合了来自《淡水螯虾世界》（World of Crayfish®，简称WoC®）平台的115191条带地理坐标的物种出现记录，并通过GeoFRESH框架提取了约400项环境变量，所用基础数据为分辨率90米的Hydrography90m河网数据集。环境变量涵盖气候、地形、土壤与土地覆盖类型，覆盖局域（河段尺度）与上游（流域聚合）两类分析尺度。经质量筛选流程后，留存了来自现存3个科（螯虾科Astacidae、螯蛄科Cambaridae、副螯虾科Parastacidae）的273个类群的65957条记录，用于开展物种水平的统计合成工作，每个类群可获得超过8000个数据点。依据WoC®社区数据保护协议，为保障物种安全，未公开该数据集的地理坐标信息。完整的方法学细节详见随附论文：Petko等题为《面向全球淡水螯虾的网络感知环境性状数据库》的投稿稿件，已投至《Scientific Data》。
