Ecological stoichiometric characteristics of Solanum rostratum organs in different habitats

This priority allocation to reproduction underscores an evolved strategy for optimizing fitness. Moreover, with changes in the invasion degree of <i>S. rostratum</i>, the soil nutrient cycle changed, with obvious differences in the responses of different habitats. This indicates that <i>S. rostratum</i> invasion not only affects its own growth but also affects the nutrient cycle of the whole ecosystem by changing the soil nutrient status. In addition, habitat type had a significant impact on the element accumulation of <i>S. rostratum</i>, and the quantitative relationship between plant and soil elements showed obvious habitat specificity. This phenomenon reflects the driving roles of environmental stress and resource availability on plant growth. <i>S. rostratum</i> adjusts its element absorption and distribution strategies under the environmental and resource conditions of different habitats as an adaptation to environmental changes. Therefore, <i>S. rostratum</i> adapts to heterogeneous environment or heterogeneous condition. Accordingly, differentiated control strategies tailored to its invasion characteristics in distinct habitats should be formulated to enhance its control efficiency.
