Self-fertilizing tropical plants exploit global trade, climate change, and colonial legacies to become invasive

Self‑fertilization confers reproductive assurance under low‑density conditions, allowing a single propagule to seed a population—a trait quantified by high seed‑set ratios and low genetic load in invasive taxa. Empirical models link autonomous selfing rates to invasion success across multiple families, reinforcing the mechanistic basis of the study. However, these findings must be contextualized within ecosystem‑level stressors to avoid reductionism.
The invasive success of self‑fertilizing tropical plants is not a simple biological curiosity but the product of historic colonial exchanges, contemporary global trade, and climate‑driven habitat disruption.
Indigenous stewardship practices and cross‑cultural horticultural norms offer concrete counter‑measures that can be woven into robust biosecurity frameworks. Scientific insights into reproductive autonomy must be coupled with future modelling that anticipates climate corridors, while artistic and trickster narratives expose the moral paradox of progress that fuels invasions. By centering marginalised voices and aligning economic incentives with ecological resilience, a multi‑layered governance architecture can transform the current trajectory from reactive eradication to proactive, justice‑oriented prevention.
