Friday Photo: A beautiful feather duster worm!

For todays photo we have a real beauty; this bristle worm (Polychaeta) from the family Sabellidae, the feather duster worms!

After being emailed this photo, one of our collaborators – who works with the Sabellidae – has identified it to the genus Euchone (Thanks, M.! ).

For an identification to species level, an examination of small details, such as the characteristics of individual bristles would be needed. Or we can barcode it and hope that a specimen from the same species has already been (correctly!) identified to species and uploaded to the database, in which case we would get a hit on “our” barcode. In this case, we hope to do both – get a name on it based on the morphology, and do genetic sequencing so that its genetic barcode can be included in the BOLD database Euchone sp. Photo: K. Kongshavn

It was collected just outside of Bergen on one of our day trips, and will be included in our ongoing effort to assemble a library of genetic barcodes for all the Norwegian marine invertebrates.

10(!) new plates ready for BOLD

We’re currently in the final stages of preparing ten plates; 9 from Norwegian waters for the Norwegian Barcode of Life project (NorBOL), and one plate of Polychaetes from the Marine Biodiversity of Western Africa (MIWA) project for submission to the BOLD database.

The shipment will consist of the following taxa groups:

1…

2….

3….

…4 plates of polychaetes (bristle worms) from Norwegian waters. These have mainly been collected by the large projects MAREANO, BIOSKAG and PolySkag, and have been identified during workshops that we have arranged.

One plate of aplacophoran molluscs

One plate of ophiouroids (brittle stars), mainly from MAREANO and BIOSKAG

One plate of ophiuroids (brittle stars), mainly from MAREANO and BIOSKAG

One plate of Amphipoda, mostly collected by MAREANO, but also samples collected during a teaching cruise from UNIS at Svalbard

One complete plate of Cumaceans…

..and one plate with Cumacea (bottom right), Mysida (bottom left) and Isopoda (top)

As well as one plate of African polychaetes.

Hopefully the sequencing will be successfull, and yield many new DNA barcodes!

More from the PolyNor workshop

As usual, we use a variety of methods to work with our animals – these include use of stereo microscope, “ordinary” microscope, and electron scanning microscope (SEM). Below are some pictures of work in progress during today.

PolyNor Workshop on the MAREANO material

This week our lab is teeming with activity as twelve researchers goes to work on our polychaete material, focusing mainly on that which has been collected by the MAREANO program.

As mentioned previously, the material collected by MAREANO gets split into size based fractions, which then receive different treatments. As far as the polychaetes go, MAREANO carries out routine identification on what is collected by grab (1 mm) and beam trawl (5 mm), all of which has been fixed in formalin (until this year, where it was begun fixing half of the beam trawl in ethanol). Thus we already have some idea of what to expect to find in the material.

At the Invertebrate Collections we have processed a lot of bulk samples from the fractions that MAREANO does not utilize, and lately we have especially focused on the Ethanol fixed material, as this can be used for genetic work.

This workshop is part of the Polychaete diversity in the Norwegian sea (PolyNor) project. This project aim to explore the diversity of polychaetes in the Nordic seas;

The Norwegian Sea holds a diverse fauna of polychaete worms, more diverse than previously anticipated. Recent work has discovered several new species and species described in the old literature but not seen since their description, has been rediscovered. Material from new samples will be targeted to discover the true diversity of polychaetes in the Norwegian Sea.

During the workshop we will work on some of the groups with especially tricky taxonomy, prioritizing the identifying of specimens fixed in ethanol, and select individuals that are especially suited for genetic work. And of course we will also discuss current topics, find and reconnect with collaborators, drink an unholy amount of coffee, and learn some new things!

The 11th International Polychaete Conference – Sydney, Australia 2013

For a hectic week in early August, the Australian Museum in Sydney was swarmed by enthusiastic people in purple hoodies, who kept talking about (bristle) worms.

It was the 11th International Polychaete Conference, with 149 attendants from 26 different countries. We had a strong Norwegian presence there – from the Museum, three of us attended (with talks and posters), as well collaborators of ours from NTNU, NIVA, and Uni Environment.

You can read more about our contributions here (if your Norwegian is up to speed – unfortunately it is not avaliable in English).

From the auditorium

It was a great week, where we got to meet and mingle with our colleagues from all over the world, learning what they are working on and how, making new connections and meeting up with old friends.

We had a excellent time, and would like to thank the IPC 2013 committee for the fantastic job they did!

The next conference will be in Cardiff, Wales in 2016, we look forward to it.
