Shrubs and precipitation interactions shape functional diversity of nematode communities on the Qinghai-Tibet Plateau

Two databases are included in this file:a sites x species matrix which includes nematode composition;a sites x environmental factor which includes soil properties and climate facotorBelow are the abbreviations, full names and units of the indicators：map: mean annual precipitation, mm; PB: plant biomass, g; sm: soil moisture, %; SOC: soil organic matter, g/kg; pH: soil pH; EC: soil electrical conductivity, μS/cm; NO: soil nitrate nitrogen, g/kg; NH: soil ammonium nitrogen, g/kg; AVP: soil available phosphorus, g/kg; TP: soil total phosphorus, g/kg; TN: soil total nitrogen, g/kg.
