Summary

Story summary

Researchers utilize environmental DNA (eDNA) and RNA (eRNA) to monitor freshwater ecosystems non-invasively.
eDNA reveals species presence, while eRNA provides real-time data on active organisms.
At McGill University’s Gault Nature Reserve, scientists studied eDNA and eRNA behavior in controlled environments.
They found RNA degrades faster than DNA, with messenger RNA (mRNA) being the most fragile.
This approach could improve biodiversity monitoring and support conservation efforts.
