Just noticed that our paper is on the cover of Trends in Plant Science - that was unexpected 😅 The illustration is really cool 💙

Unlocking Demography: Developing an eDNA‐Based Toolkit to Measure Sex Ratios From Populations Demographic information, such as sex ratios, is essential for understanding population dynamics and informing conservation strategies. Yet obtaining sex ratios in natural populations can be challengi....

🔥 Hot off the press: ever wonder if you could get demographic info for natural pops with #eDNA #environmentalDNA? Well wonder no more! First proof of principle for sex-ratios coming to a computer screen near you: onlinelibrary.wiley.com/doi/10.1111/...

Spiders inspired biologists to create artificial webs to capture airborne DNA for biodiversity monitoring Natural spiderwebs are good at capturing DNA from the environment, but artificial webs are cheap and provide better control – without harm to spiders.

A Conversation piece on our (@manpreetkdhami.bsky.social @sbirdy.bsky.social) quirky fake spiderweb research for eDNA biomonitoring, just out in time for Halloween. Paper forthcoming!

Such a fun study with awesome collaborators! Read the news release ahead of the paper on how fake webs yielded real eDNA hits. Happy Halloween 👻

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.
