Local genetic reference sequences can be essential for species specific studies. Applying what worked for a species elsewhere in the world (in this case largetooth sawfish, Pristis pristis) may not work where you are!!! www.biorxiv.org/content/10.1...

DIYNAFLUOR: An Affordable DIY Plug-and-Play Nucleic Acid Fluorometer for eDNA Quantification in Resource Limited Settings Nucleic Acid (NA) fluorometry is widely employed for quantifying environmental DNA (eDNA) samples and their downstream DNA sequencing libraries, owing to its sensitivity, accuracy, and speed. However,...

A Preprint for our ~$40 USD, open source, 3D printed DNA Fluorometer, the #DIYNAFLUOR, has just been posted to bioRxiv outlining its performance and applications for #eDNA analysis!🦕🧪🧬

A big thanks to all the co-authors!

The Long and the Short of It: Nanopore‐Based eDNA Metabarcoding of Marine Vertebrates Works; Sensitivity and Species‐Level Assignment Depend on Amplicon Lengths To monitor the effect of nature restoration projects in North Sea ecosystems, accurate and intensive biodiversity assessments are vital. DNA-based techniques and especially environmental (e)DNA metab....

Super happy our paper on #eDNA #metabarcoding of North Sea fish using @nanoporetech.com sequencing is finally published in Molecular Ecology Resources: onlinelibrary.wiley.com/doi/10.1111/...

We officially kicked-off eDNA-OPTIMA. In this project, we deploy samplers on a USV, improve detection of benthic invertebrates, aim to understand how eDNA is transported by ocean currents, etc.

I'm very proud to coordinate this project with this fantastic team. We will gain a lot of insights in how to optimize the use of eDNA for species detection in a complex coastal ecosystem.
