Using eRNA-based metatranscriptomics, we uncovered how freshwater eukaryotic communities respond to environmental stress — expanding the potential of eRNA for tracking biodiversity and functional responses across diverse taxa.

New paper out in Molecular Ecology! We used eRNA-based metatranscriptomics to characterize freshwater eukaryotic communities and analyze gene expression responses to environmental stress across diverse eukaryotic taxa. @wbmorgadog.bsky.social #eRNA #eDNA onlinelibrary.wiley.com/doi/10.1111/...

Excellent review on environmental RNA — clear overview of advances and challenges in this fast-moving field.

In environmental genomics, DNA & RNA from water, soil, or air let us detect biodiversity and support conservation.
But it all starts with careful sampling — avoiding contamination and running quality checks to ensure reliable results. 🌍✨

These tiny freshwater organisms helped us study how environmental DNA & RNA (eNAs) degrade and persist in water. Even the smallest creatures can reveal big insights about biodiversity and ecosystem health. @biomcgill.bsky.social

It's not all about DNA. RNA could transform real-time environmental surveillance.

By vanishing quickly, RNA avoids DNA’s problem of lingering too long, giving ecologists a sharper, more immediate picture of life in lakes, rivers, and beyond.

How environmental RNA can give us a real-time picture of freshwater biodiversity

Excited to share a new Conversation article with @otournayre.bsky.social 🧬at @biomcgill.bsky.social
We show that environmental RNA, long considered too unstable, can actually give us a snapshot of what’s alive right now in lakes and rivers.

📢 New #eDNA and #eRNA study!🧬
We used dPCR to compare #decay rates and #detectability across 4 #markers (16S, 18S, COI, LDHA) in 1000L freshwater mesocosms.

New study published in MER: eDNA/eRNA decay and detectability in connected 1000-L mesocosms. eRNA decays faster than eDNA; digital PCR quantified detection across a wide dilution gradient (to 1:10,000). OA: doi.org/10.1111/1755...

🎉Our paper is out in Molecular Ecology Resources! We tracked eDNA vs eRNA decay in connected & isolated 1000-L mesocosms using dPCR. eRNA decays faster, and both signals can move across the network. OA: doi.org/10.1111/1755...
