Data for journal manuscript: Trait-based adaptability of Phragmites australis to the effects of soil water and salinity in the Yellow River Delta
<p><span><span><i>Phragmites australis</i> is the dominant species in the Yellow River Delta and plays an important role in wetland ecosystems. Ecological responses of the <i>P. australis</i> community to soil properties were investigated in 96 areas along the coastal-inland regions in the Yellow River Delta of China. The aim was to evaluate the relationship between phenotypic variation and environmental factors, reveal which functional traits could well respond to changes in electrical conductivity and soil water content, and the ecological strategies of <i>P. australis</i>. Within the range of soil water content (9.39–36.92%) and electrical conductivity (0.14–13.29 ms/cm), the results showed that the effects of soil water content and salinity were not equally important for the characterization of the morphological and physiological variability, and that plant functional traits including leaf traits and stem traits responded more strongly to soil salinity than soil water content. Our results suggested that salinity leads to reduced average height, specific leaf area, leaf area, and base stem diameter, but increased leaf water content and leaf thickness. The relationships between functional traits and electrical conductivity were generally linear and logarithmic. The coefficients of variation of morphological traits showed more phenotypic plasticity than the physiological traits. Salinity also led to the stress tolerator/competitor-stress tolerator (S/CS) strategies of <i>P. australis</i>;<i> </i>with the decrease of environmental stress, the main strategy gradually moved to the competitor (C) strategy, making <i>P. australis</i> the dominant species in the Yellow River Delta. </span></span></p>
