Seaweeds continued

An alternate world?

An alternate world?

The week flew by in a flurry of Latin names, literature and sea water – today is the day for unpacking, making sure that everything is stored safely, and revising lists.

An impressive collection of species on the final day!

Tissue samples

In total we collected 88 samples of 76 different species, most of which are not in the BOLD database for Norway yet. It will be exciting to see what results we get!

The tissue samples will be sent to the Saunders lab, as they have kindly offered collaborate on this collection and help us with the sequencing as our go-to lab in NorBOL is not optimally set up to deal with algae.

Thank you so much to all the students and teachers for being so welcoming, and for being good sports about me spiriting away your specimens!

On the hunt for seaweeds!

This week the invertebrates are forced to take second place (!) as I have joined the master students participating on the course BIO309A – marine floristics out at our field station.

Lab work

The course is the sister course to Marine faunistics that I joined in on last fall. The focus of this week is the macroalgae; the seaweeds that most people are (passingly) familiar with. (The micro algae have been covered in lectures and lab work back at BIO earlier.)

We are doing a mix of field work and lab work. Every day we go out and sample, and bring the catch back to the lab to identify it. 1-2 specimens of each species that is identified is destined to become barcode vouchers for NorBOL, and go through the by now fairly familiar route of photo-tissue sampling-preservation for inclusion in the museum collection as a voucher. Seaweeds fixate badly in ethanol, so instead we are pressing them and making herbarium specimens. So far we have about 50 vouchers (from almost as many different species), and the number is sure to climb as we continue working our way through the fresh stuff we just collected.

Amphipod-Thursday. WoRMS – (all) about amphipods

It is a sad fact, but a fact nonetheless. Most biologists are not taxonomists. Even so – the work many biologists do is based on knowing the species studied, and knowing the correct name is part of that important knowledge.

But how do we know what names are valid, and what species have been formally described within a group? Taxonomic revisions tend to have name-changes as a result, and new species are described all the time – for amphipods an average of 140 species new to science are described yearly…

This is where databases will be your best friend! For marine species, the World Record of Marine Species, WoRMS, database is used widely, with more than 200 000 visits every month. Here you can find not only current accepted names, but also information about synonymised names, taxonomic literature, and for some species information about distribution, ecological traits and links to other resources. The data have all been checked and edited by a world-wide team of taxonomic and thematic editors – all responsible for their special groups of organisms.


IMG_9037This week, 22 of the 34 taxonomic editors of the World Amphipoda Database, feeding WoRMS with all Amphipod-related information, gathered at the Flanders Marine Institute in Oostende, Belgium to learn about how to best edit the information about Amphipods. It was two days full of information about the database, but also of hands-on training and with the help of the nice people in the Data Management Team of WoRMS, we managed to get quite a lot of information added and edited on the database. Needless to say, with more than 9000 amphipod species accepted (and several of them with earlier names or alternate representations), we have not completely finished yet. The work on editing a database is continuous – and we have plans for adding more info for each species, including type-information, ecological information and links to identification keys.


The second best thing about going to workshops (the first being all the exciting new things we learn), is that we get to spend time with colleagues from far away. The people working on amphipods are in many ways my extended family – this is at least how it feels whenever we meet. News about both amphipods and life in general are exchanged, possible new projects are planned, and friendships continue to be reinforced over cups of coffee, early breakfasts and late dinners. And every time we leave each other, there is a hope that our next meeting might not be too far away.  My colleagues from Poland call this “the Amphipoda way of life”  – and this friendly, collaborate life is a good life to have as a researcher.
