What’s new

New midge species named after Paul Hebert

19/10/2017

In an article recently published in the journal Insect Systematics and Evolution, Xiaolong Lin describes eight species of non-biting midges new to science.

“It is particularly rewarding to find and describe new species from a well investigated area such as Norway” says Lin, “but also exciting to find new species from my home country China”.

Non-biting midges, or chironomids, are small insects, and a compound microscope must be used to see the subtle differences between closely related species. However, they are easily separated by DNA barcodes.

“Because several of the new species first were detected using DNA barcoding, it was a natural thing to name one of them after the father of DNA barcoding Paul Hebert”, Lin explains. “The fact that this species is found in Arctic Canada, an area where Hebert have worked intensively, was particularly nice”, he says.

Tanytarsus heberti, the small midge of 2,5 mm from Churchill and Wapusk National Park in Manitoba, can be separated from its closest relatives by its lighter body colour, small details in the male genitalia and a characteristic DNA barcode.

Co-authors and supervisors Elisabeth Stur and Torbjørn Ekrem at the NTNU University Museum elaborates:

“Xiaolong has done a very thorough and good investigation of this group of non-biting midges. Not only does he describe new species in his thesis, but he analyse their evolutionary relationship and geographical distribution. This is a great contribution to our knowledge of a species rich and important group of insects”.

Paul Hebert to talk at the Starmus-festival

07/03/2017

What does Stephen Hawking, Buzz Aldrin, Paul Hebert, Oliver Stone and 10 Nobel Laureates have in common? They will all speak at the Starmus Festival: Life and the Universe in Trondheim, June 18-23, 2017!

STARMUS – Life and the Universe

Starmus is a grandiose festival. With it’s star-speckled list of speakers and artists, Starmus has as goal to bring an understanding and appreciation of science to the public at large. This is the fourth Starmus festival and as in previous years, astronauts, physicists, astrophysicists, biologists and musicians will be speaking about life, the universe and things that (dark) matter. The program is still under development, but it is already certain that the festival in Trondheim might become a ‘once in a lifetime experience’.

So, what will the ‘father of DNA barcoding’ Paul Hebert speak about in this setting? Could it be the Planetary Biodiversity Mission? The microbiologist Emmanuelle Charpentier, the molecular biologist Susumu Tonegawa, the astrobiologist Nathalie A. Cabrol, the marine biologist Nancy Knowlton and the neurobiologists May-Britt and Edvard Moser are other famous biologists in the program.

In addition, three moonwalkers will have a public conversation about the moon and beyond. That will also be interesting, guaranteed.

DNAqua-Net: a COST-Action for developing new genetic tools for bioassessment of aquatic ecosystems in Europe

01/11/2016

dnaqua_net-logo

From the COST-Action CA152119 websiteThe protection, preservation and restoration of aquatic ecosystems and their functions is of global importance. For European states it became legally binding mainly through the EU-Water Framework Directive (WFD). In order to assess the ecological status of a given water body, aquatic biodiversity data are obtained and compared to a reference water body. The quantified mismatch thus obtained determines the extent of potential management actions. The current approach to biodiversity assessment is based on morpho-taxonomy. This approach has many drawback such as being time consuming, limited in temporal and spatial resolution, and error-prone due to variation of individual taxonomic expertise of the analysts. Novel genomic tools can overcome many of the aforesaid problems and could complement or even replace traditional bioassessment. Yet, a plethora of approaches are independently developed in different institutions, thereby hampering any concerted routine application. The goal of this Action is to nucleate a group of researchers across disciplines with the task to identify gold-standard genomic tools and novel eco-genomic indices for routine application for biodiversity assessments of European water bodies. Furthermore, DNAqua-Net will provide a platform for training of the next generation of European researchers preparing them for the new technologies. Jointly with water managers, politicians and other stakeholders, the group will develop a conceptual framework for the standard application of eco-genomic tools as part of legally binding assessments.

The inaugural meeting of DNAqua-Net was held in the COST-building in Brussels on October 20, 2016. The COST-Action was formally accepted and chair and working group leaders were elected. So far 31 countries are associated with the action, med representatives in the Management Committee nominated by national COST-coordinators. The delegates from Norway are Trude Vrålstad (Norwegian Veterinary Institute) and Torbjørn Ekrem (NTNU University Museum). The first conference of DNAqua-Net will be held in Essen, Germany, March 6-8, 2017, with post conference meetings in the five working groups (leads in parentheses):

  • DNA Barcode References (Torbjørn Ekrem, Norge + Fédor Ciampor, Slovakia)
  • Biotic Indices & Metrics (Jan Pawlowski, Sveits + Maria Kahlert, Sverige)
  • Lab & Field Protocols (Kat Bruce, UK + Emre Keskin, Tyrkia)
  • Data Analysis & Storage (Kessy Abarenko, Estland + Diego Fontaneto, Italia)
  • Implementation Strategies & Legal Issues (Patricia Mergen, Belgia + Daniel Hering, Tyskland)

Natural History Museum at the Oslo Science Fair

01/11/2016

The Natural History Museum in Oslo and NorBOL participated at the Oslo Science Fair September 23-24, 2016. At our stand we communicated challenges with biological, morphological and genetic species definitions. Fifteen hundered shots of juice were served with the task of identifying which three fruits the juice was composed of. To help them with the task, people received visual DNA barcodes of the fruits as well as a reference library of fruit barcodes. Many learned how DNA barcoding can be used to determine the content of food.

NorBOL at Researchers’ Night 2016

01/11/2016

On Friday September 23 time had come for Researchers’ Night in the NTNU Science Building. Like previous years, the interest for participation was great and more than 1100 high school students trawled the stands, attended lectures and visited labs at NTNU. NorBOL was present with a stand on DNA barcoding and LifeScanner.

At our stand, students and teachers were challanged to do practical DNA barcoding: Three visualized DNA sequences from unknown prey had been retrieved from a boreal owl pellet and could be compared to known sequences in a reference library. The task was not necessarily simple and created good discussions among the participants. As prize and proof of particpation, the stydents received #mydnabarcode stickers.

Mushroom Day at Tromsø University Museum

06/09/2016

Every year in the mushroom-season, the Tromsø Mushroom Society arrange mushroom check-points at the Tromsø University Museum where the general public can have their collected mushrooms identified. They also invite to guided tours and celebrate “Mushroom Day”. NorBOL attended all check-points so far this year and has received plenty of species for DNA barcoding.

“Mushroom Day” was held at Tromsø University Museum on September 4th and included an exhibition of freshly picked specimens as well as the regular check-point and a local guided tour. NorBOL attended the event and received about 20 new species for barcoding. Most of these came from the exhibition made by the Mushroom Society, but some were also donated by the visitors.Sopputstilling på soppens dagMushroom exhibition on Mushroom Day. Photo Marie K. Føreid Merkel CC-BY.

During collection of specimens for the exhibition, one new species to North Norway was found. This specimen will be barcoded. NorBOL staff used the opportunity to talk to visitors about DNA barcoding, the work that they do and how mushrooms are preserved and stored in the scientific collections at the museum. So far, NorBOL har received more than 120 species from the area of Tromsø, with great help from the Mushroom Society.

We hope that the last to check-point dates (11 and 18 September) will bring in even more specimens, and that we can continue our outreach on DNA-barcoding to the general public. Thanks to the Tromsø Mushroom Society for excellent collaboration!

Barcode of Life conference heading for Kruger National Park

04/08/2016

Imagine this: You wake up before the sun rises, find your guide and get set for today’s “morning drive” to watch elephants, lions and rhinoceros as the first rays of sun hit the bushland. You return to the camp and enjoy an excellent breakfast before the first plenary of the day on environmental barcoding of North American wetlands. This dream can come true before you realize: The seventh Barcode of Life conference will be held in Kruger National Park, South Africa, 20-24 November 2017.

The international conferences on DNA barcoding have been held every second year since 2005 (in London) and have continuously increased in size and content. The participants come from all over the world and present their research, educational programs and public outreach initiatives. All aspects of DNA barcoding and metabarcoding are covered and the presentations can include anything from development of methods and taxonomy to citizen science, applied ecology and nature management. The last meeting in Guelph (2015) had 600 participants from 60 countries. Time will tell if the upcoming meeting can beat those numbers…

The scientific program for the meeting is under development, but several invited speakers have already accepted. The theme of the conference will be “Exploring mega-diverse biotas with DNA barcodes”. Registration will open December 1, 2016 and end November 1, 2017. The main lecture hall has room for 700 guests, so the meeting probably will not be fully booked the first week. Nevertheless, it might be a good idea to sign up early!

See you in Kruger!
