DNA in sediments tells a longer story!
New research shows sedimentary #eDNA can persist up to 132 days & be up to 1800x more concentrated than in water.

What do you think about this?

Fish environmental DNA is more concentrated in aquatic sediments than surface water
Genetic identification of aqueous environmental DNA (eDNA) provides site occupancy inferences for rare aquatic macrofauna that are often easier to obt…

For the first time this Spring, NOAA adopted eDNA into a formal stock assessment of Pacific Hake and this was supported by the Scientific Review Group for the Pacific Fisheries Management Council.

Our other (slightly younger) old lady Syra is a kelpie-husky-malamute mix and she does like to run with me. Never tried her with a sled but I reckon she’d have been speedy when she was younger!

I think she’d have a threshold where she’s just stop and sulk! Never had the heart to test it ;)

What a lovely old sled dog. You can see the age and wisdom. Would steal my heart too!

Definite similarity :) Sakura is part Labrador though, and always more interested in cheese than running long distances!

This is great - we a huge need in the #eDNA community to have data-informed standards for eDNA identity cutoffs, not just the bog-standard 97%
besjournals.onlinelibrary.wiley.com/doi/full/10....
For Chordata there is no cutoff that leads to 0% error when assigning species!! (Table S4)
Taxon‐specific BLAST percent identity thresholds for identification of unknown sequences using metabarcoding
The identification of organisms in environmental samples using metabarcoding relies on factors such as taxonomic assignment methods, genetic markers, reference databases and confidence thresholds ...
