Somewhat stunned by the fact that my DNA barcode browser I described earlier was one of the (minor) prizewinners in this year's GBIF Ebbe Nielsen Challenge. For details on the winner and other place getters see ShinyBIOMOD wins 2020 GBIF Ebbe Nielsen Challenge. Obviously I'm biased, but it's nice to see the challenge inspiring creativity in biodiversity informatics. Congratulations to everyone who took part.

Motivated by the 2020 Ebbe Nielsen Challenge I've put together an interactive DNA barcode browser. The app is live at https://dna-barcode-browser.herokuapp.com. A naturalist from the 19th century would find little in GBIF that they weren’t familiar with. We have species in a Linnean hierarchy, their distributions plotted on a map.

Earlier this year I stopped over in Singapore, home of the spectacular "supertrees" in the Garden by the Bay. The trip was a holiday, but I spent a good part of one day visiting Rudolf Meier's group at the National University of Singapore. Chatting with Rudolf was great fun, he's opinionated and not afraid to share those opinions with anyone who will listen. Belatedly I've finally written up some of the topics we discussed.

Following on from earlier posts exploring how to map DNA barcodes and putting barcodes into GBIF it's time to think about taking advantage of what makes barcodes different from typical occurrence data. At present GBIF displays data as dots on a map (as do I in http://iphylo.org/~rpage/bold-map/). But barcodes come with a lot more information than that.

Some notes to self about future directions for the "million DNA barcodes map" http://iphylo.org/~rpage/bold-map/. At the moment we have an interactive map that we can pan and zoom, and click on a marker to get a list of one or more barcodes at the location. We can also filter by major taxonomic group. Here are some ideas on what could be next. Search At the moment search is simply browsing the map.

A little over a week ago I was at the 6th International Barcode of Life Conference, held at Guelph, Canada. It was my first barcoding conference, and was quite an experience. Here are a few random thoughts. Attendees It was striking how diverse the conference crowd was. Apart from a few ageing systematists (including veterans of the cladistics wars), most people were young(ish), and from all over the world.

On a recent trip to the Natural History Museum, London, the subject of DNA barcoding came up, and I got the clear impression that people at the NHM thought classical DNA barcoding was pretty much irrelevant, given recent developments in sequencing technology. For example, why sequence just COI when you can use shotgun sequencing to get the whole mitogenome? I was a little taken aback, although this is a view that's getting some traction, e.g.
