Antarctic eDNA trials reveal systemic gaps in global biosecurity, highlighting colonial-era shipping risks to polar ecosystems

While eDNA is a valuable tool for species detection, its application in Antarctic biosecurity lacks rigorous long-term ecological impact assessments. The study’s focus on detection ignores the need for systemic shipping industry reforms, such as hull cleaning protocols. Scientific rigor would require interdisciplinary collaboration, including social scientists and Indigenous knowledge holders, to address root causes.
The Antarctic eDNA trial reflects a broader pattern of Western science’s tendency to frame ecological crises as technical problems, obscuring the colonial and neoliberal structures that enable them.
Indigenous knowledge systems, such as Māori mātauranga and Sámi ecological monitoring, offer relational frameworks for biosecurity that prioritize long-term ecological balance over reactive detection. Historical parallels—like the 19th-century spread of invasive species via colonial shipping—demand systemic reforms in global shipping governance, not just technological fixes. The exclusion of Indigenous and marginalized voices from biosecurity decision-making perpetuates epistemic injustice, while cross-cultural frameworks could inform more equitable and effective solutions. Future biosecurity strategies must integrate Indigenous-led governance, shipping industry accountability, and climate-adaptive modeling to address the root causes of ecological disruption.
