Thanks Pedro! Hope you enjoy the read.

The bottom line? #Rivers aren't just pipes; they are complex exchangers that store and release genetic information and studying the sediment in addition to the water column might be where the secret is hidden. 🐟

Settling Dynamics: We quantified eDNA settling velocity under controlled quiescent conditions. We found it behaves similar to fine particulate organic matter.

Flow Regime Controls Transport: a) Low Flow: #eDNA moves slower than the water itself! Adsorption and "hyporheic exchange" delay downstream movement. b) High Flow: #Turbulence takes over. Higher shear stress suppresses adsorption, keeping eDNA suspended in the water column.

The Riverbed acts as a Filter: We found that substrate matters. While eDNA moves more conservatively over smooth beds, gravel beds act like a filter, trapping genetic material in pore spaces. Surface-subsurface interactions significantly enhance retention rates.

The study explores the physics behind #eDNA transport. Here are the key takeaways on how riverbeds and flow dictate where we find genetic signals:

Laboratory Study on Fate and Transport of Water-Borne eDNA: A Tale of Tempered Tails and Parafluvial Processes Environmental DNA (eDNA) has emerged as a powerful marker for assessing species presence in flowing waters; however, estimating the spatial and temporal origins of these signals remains a challenge. T...

Big milestone today: My first PhD paper is officially out! We took a deep dive into eDNA transport dynamics in flowing waters. Check out the full study in ES&T.
