Fluctuated water depth with high nutrient concentrations promote the invasiveness of Wedelia trilobata in Wetland

Abstract The distribution of invasive and native species in wetlands is determined by hydrological conditions; whereas conditions such as water depth fluctuations, variations in the nutrient concentrations are expected to affect the growth and physiological traits of plants. For the assessment of su...
