Elasmobranchs in offshore wind farms The development of offshore wind farms (OWFs) in coastal seas presents both risks and opportunities for threatened elasmobranch populations, but their…

Offshore wind farms have a variety of ecosystem impacts. More hard habitat= more invertebrates at the base of the food chain.

Seafloor cables transport electricity to shore- this can affect electrosensitive sharks and rays. 🧪🦑🌎🦈🐠

Dorado is 1.0! 🎉

LC25 release adds v5.2 DNA/RNA models with a new suite of mod models that are higher accuracy, lower FP rates, and significantly faster.

- Introducing dorado variant 👀
- HAC error rate is down over 25%.
- New 2’Ome mod models
- Hopper & Blackwell SUP speed ups

Now clear how much extra information from @nanoporetech.com data - especially full transcripts #nanoporeconf

At London Calling, Rosemary Sinclair Dokos and Lakmal Jayasinghe shared how we’re doubling down on what matters: delivering a future-ready platform with proven performance across DNA, RNA, and now proteins. Click here to discover what’s new – and why it matters: nanoporetech.com/news/london-...

Are offshore wind farms the next safe spaces for sharks and rays? - Oceanographic New eDNA evidence has confirmed the presence of active shark and rays around Dutch offshore wind farms, posing an exciting new question.

Our previously published paper was picked up in local Dutch news as well as here, very exciting to see the media take notice of this work 🦈

Great windfarm - elasmobrach #eDNA research by Auriel Summer-Hempel @reindertn.bsky.social @aquaecomics.mastodon.social.ap.brid.gy

The reviewer identified a mismatch in the last nucleotide of the 3` side of the forward primer targeting the 12S region, for several species in the order of Gadiformes. The details of that error and its correction are now presented in the supplemental data: onlinelibrary.wiley.com/action/downl...

Getting this published was a long process, and taught us a lot. We initially made an error in the primer design of our new 2kb 12S-16S amplicon. This was fortunately identified by a added new reviewer in the third review round. So all experiments had to be repeated with updated, correct primers...

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.

I sequenced total genomic DNA on a previously used flow cell. I got about 2x coverage of the whole genome and >100 fold for the mitogenome.

Alignment of raw nanopore read to create a consensus seqeunce, showing very litte errors in the raw read data

Annotated overview of the mitogenome assembly from Goneplax rhomboides

I sequenced and assembled the full mitochondrial DNA of the angular crab (Goneplax rhomboides) using the @nanoporetech.com #MinION #Mk1D, so #nanopore only. The raw read quality really is amazing, and the assembly looks perfect!

My baby Small-spotted catsharks are still happy, and so much fun to watch!

These are juvenile small-spotted catshark (Scyliorhinus canicula) hatched in August this year. So cool!

Automatic sampling underwater - Resource online Measuring biodiversity without divers.

At Marine Animal Ecology (WUR) we are developing a Biodiversity Sensing box, which combines imaging (both fish and microscopic plankton), acoustics and environmental DNA (eDNA) for marine biodiversity monitoring. More information in the article below

We recently published a forum article in Trends in Ecology & Evolution on "Edge computing in wildlife behavior and ecology". One of the presented cases is our biodiversity/fish sensing box:
