Differential kin interactions between invasive and native plants: evidence from Alternanthera philoxeroides and its native congener:Dataset and R analysis code

Research content: Reduced competition among kin can enhance plant performance, especially under resource limitation. To explore whether such effects differ between invasive and native species, we conducted a greenhouse experiment using the invasive Alternanthera philoxeroides and its native congener A. sessilis. For both species, we grew central plants with three intraspecific neighbor kinship treatments (kin only, nonkin only, and both kin and nonkin [mixed] neighbors) under two watering conditions (well-watered and drought-stressed). We also grew central plants alone as controls under both watering conditions.Dataset contents: Raw and processed data and R scripts for data analysis.
