Would you like to see your favorite DNA barcode photo on norbol.org? A beautiful (some think scary) photo has dominated our front page for a while, and it is time for a change. NorBOL is therefore inviting you to a photo/illustration challenge where the winner will have her/his contribution on the front page of norbol.org and receive a #mydnabarcode buff and a #mydnabarcode mug. Send your best photos or illustrations to Torbjørn by the 15th of February to participate. The image must be in landscape format and the winner will be chosen at the NorBOL steering group meeting on March 2. Good luck!

The symposium Biodiversity and DNA Barcoding was held at the Scandic Nidelven hotel 11-12 November 2015. Nearly 100 participants from Norway, Sweden, Canada, Finland, Germany, Czech Republic and UK had found their way to Trondheim, making this meeting larger than originally expected. The conference turned out to be a good meeting place for nature managers, barcoders, participants in the Norwegian Taxonomy Initiative and others interested in biodiversity and DNA barcoding.

As the program can confirm, there was a great diversity in the talks, both on topics and organism groups. We were guided through taxonomic challenges in fungi, marine invertebrates and insects, many of which has been detected with the aid of DNA barcodes. We were invited on journeys into the deep oceans and into the “moss forest”, and introduced to the opportunities molecular methods give when studying food webs, pollination and microscopic organisms.  We also learned about the The Planetary Biodiversity Mission, news from BOLD4 and about LifeScanner, a citizen-science initiative where identification of species through DNA barcoding is made available to everyone.

Both organizers and participants seemed very pleased with the conference. Most things went as planned, the food was good, and even if we had music from the neighbouring room accompanying the last presentations on day two, the participants seemed pleased when leaving the venue. Thank you all for coming! More photos are available on Flickr.

Antarctica is a land of superlatives with biota exposed to the steepest chemical gradients, driest soils, and extreme temperature fluctuations. These conditions, coupled with a history of 80 million years’ worth of glacial cycles have shaped an ecosystem characterised by low biodiversity. Robert F. Scott may be forgiven for stating “we have seen no living thing, not even a moss or a lichen” whilst in the Dry Valleys during 1903.

In an area of the Ross Sea region spanning more than six degrees of latitude there are only 10 species of springtail, separated into three distinct biogeographic zones each with three (and in one case four) unique species. Springtails are an important feature of terrestrial Antarctic systems as they are not only the largest year-round inhabitants at a mere1.5mm (with penguins and seals spending much of their time offshore), they are also highly sensitive to environmental disturbances, making them ideal bioindicators of climate change.

Our most recent work this past season focussed on the “middle” biogeographic zone which revealed a total of six BINs from the original three species present. These three new BINs were between 5-12% divergent from their nearest neighbours. The discovery of these new BINs is a further example of the growing realisation that whilst comparatively depauperate in the global sense, Antarctica is much more diverse than it was once thought to be. This is particularly true in the case of genetic diversity, with the rise in molecular techniques revealing high levels of cryptic biodiversity within Antarctic arthropods. The application of molecular clock dating techniques further suggested that these BINs separated 3-5 million years ago. It was during this time that the Western Antarctic Ice Sheet (WAIS) was thought to have completely collapsed. This phenomenon would have resulted in sea levels rising and increased dispersal opportunities for Collembola via meltwater streams and open sea-ways before the WAIS eventually reformed. The various BINs appear to have remained in relative isolation ever since. The presence of these unique genetic differences means that any future changes in species’ distributions can be easily tracked through the DNA barcoding of individuals. From this, we can further enhance our capacity to detect subtle biological responses resulting from gradual climate changes.

In August, I gave a presentation at the 6th international Barcode of Life conference on my master’s thesis work assessing the distribution and genetic diversity of Antarctic springtails (Collembola). For this presentation I was generously awarded the NorBOL Prize for Excellence in Polar Research. I really enjoyed sharing my work with the wider barcoding community and look forward to hopefully getting involved in polar research in the future.

The sixth international conference on DNA Barcoding just recently ended with wise words from Thomas Lovejoy, Dan Janzen and Paul Hebert: The species on our globe are going extinct faster than ever before and we have an urgent need to retrieve more knowledge of our biodiversity before it is gone for good.

The conference in Guelph, Canada was impressive in all sorts of ways and the scientific depth truly underlined the theme “Barcodes to biomes”. With more than 30 excellent invited speakers and 600 delegates from 60 countries, the meeting became an unparalleled academic success. Abstracts from all talks and posters have been peer-reviewed and published in the journal Genome.

In addition to the academically strong profile, the organizers clearly had valued good social settings in the planning of the conference. Moreover, a few other special arrangements made this a memorable event: The group photo (or rather film) was shot with a drone, the conference had its own beer (that had been barcoded of course) and the talks of all invited speakers was streamed live on YouTube. Most impressive, however, was perhaps that the results from a bioblitz held in a nearby reserve the day before the conference were ready by the end of the meeting! The specimens have been barcoded and the results assembled in a paper with 120 authors already submitted to the Biodiversity Data Journal. If you think I am the only one that is impressed by the 6th International Barcode of Life Conference, check out tweets with the hashtag #dnabarcodes2015.

The meeting decided to establish the International Society for the Barcode of Life (ISBOL) and an interrim board will be established to work out the guidelines and tasks for the society. Two important areas will be the development of new standards for DNA barcoding as technology advances and support the organization of international conferences.

It will be difficult to exceed this year’s conference in scientific breadth and organization. Perhaps this was one the reasons why Prof. Michelle van der Bank from the University of Johannesburg suggested the Krüger National Park as venue for the next conference in 2017. A setting in one of the world’s most famous protected wildlife areas certainly should attract many participants!
