Tropicalisation and other climate‐induced range shifts are rapidly restructuring global biodiversity patterns. The detection of range shifts is often complex and requires big‐data approaches. Environmental DNA (eDNA) monitoring is emerging as a powerful method for assessing biodiversity changes at unprecedented spatial and temporal resolutions. While eDNA‐based methodologies continue to evolve, the impacts of species traits and eDNA dynamics are rarely measured, though they likely affect our eDNA data interpretation. Here we combine diverse methodologies to better understand processes affecting eDNA data and to elucidate how eDNA dispersal influences the interpretation of eDNA results in a tropicalisation context.
