Mapping the Seasonal Rhythm of eDNA for Coastal Invasive Species Detection

Seasonal eDNA rhythms reveal predictable patterns of coastal invasion. By analyzing 2,663 weekly samples across five Northwest Atlantic locations, we found that species like *Botrylloides violaceus* and *Carcinus maenas* exhibit coherent phenological cycles that shift with latitude. These eDNA signals often precede or extend beyond observable settlement periods, capturing ecological dynamics conventional monitoring misses. Understanding this temporal ecology improves surveillance design and forecasting.
