Towards non-invasive and integrative biodiversity monitoring in a changing world: the promise of environmental DNA

Human activities have been reshaping biodiversity patterns on a global scale for decades. Yet, our ability to detect species and track their distributions over time and space remains limited, a challenge frequently highlighted by major international initiatives. Current monitoring methods, while extremely valuable, often come with important limitations: they are often taxon-specific, invasive, and difficult to apply at large scales. In this seminar, I will present my work using environmental DNA (eDNA) collected from several sources, including guano, water, and air. Through several case studies, I will demonstrate how analyzing DNA traces in environmental samples is transforming biodiversity monitoring and enabling assessments of anthropogenic impacts across scales and ecosystems.
