Spring time is hydrozoan time

Spring means warmer temperatures, increasing daylight, flowers blooming everywhere… and a lot of outdoor and outreach activities for our projects at the Invertebrate Collections of the museum! In particular, project NorHydro started last month with a kick-off workshop (read more about it here) and we have not stopped collecting specimens, attending conferences, teaching courses and joining sampling trips since then. But why is it that spring is such an important time for hydrozoans and NorHydro?

Well, for starters, spring is the reproductive season for many species of hydrozoans in Norwegian waters. Most Norwegian hydrozoans are seasonal animals and for many of them the increasing temperatures and daylight of March and April trigger a shift in the life cycle towards the production of reproductive stages.

Tiny hydromedusae were already being produced in many of the hydroids we collected, like these colonies of Sarsia tubulosa (left) and Obelia dichotoma (right). Pictures: Luis Martell

The reproductive stages are often necessary to correctly identify a hydroid colony to species level, so we took advantage of the season to collect the very first samples of the project during the kick-off workshop. More than 50 samples of hydrozoans were collected thanks to the efforts of all the participants, and special thanks are due to NorHydro’s team of hydrozoan experts for identifying the specimens and making for a great start of the project.

Peter Schuchert from the Natural History Museum of Geneva was a very special participant in this meeting, where he kindly shared his extensive expertise with us. Peter’s knowledge of hydrozoans is impressive, and it was a real pleasure to learn from him on everything from collecting methods to preservation techniques and species identities. Completing our team of experts were our very own Aino Hosia from the University Museum, who stopped by to share some of her experiences on hydrozoan diversity in the region, and Joan J. Soto Àngel from the Sars International Centre for Marine Molecular Biology, who collected many specimens and participated in several interesting discussions about the expected outcomes and potential subprojects of NorHydro.

Our samples were full of hydroids, most of which were documented and preserved for future DNA work. Pictures: Luis Martell and Joan J. Soto Àngel

Of course one of the great advantages for NorHydro during the workshop was the possibility to learn from the activities and results of our sister projects Sea Slugs of Southern Norway and Hardbunnfauna, and to share experiences with them and with the members of the university’s student dive club (SUB-BSI). With such amazing partners and professional collaborators, it was impossible for the kick-off workshop not to be a big success, so thank you all for giving NorHydro the best possible start!

We had all types of weather during the workshop, going from almost-summer to snowy-winter in the same day! Pictures: Luis Martell

JESS! It’s World Jellyfish Day!

November 3 is World Jellyfish Day, and it is the perfect opportunity to celebrate the gelatinous creatures of the world by sharing experiences and plans with friends and colleagues. We at the Invertebrate Collections take every chance to share our love for jellies, which is why Aino and I were particularly happy to participate in the Jellyfish Research in Svalbard (JESS)-Workshop held last week in Tromsø (22-23 October).

Some examples of Arctic jellies. From left to right, in the top row: Catablema multicirratum, Beroe abyssicola, Botrynema ellinorae, Euphysa flammea; bottom row: Dimophyes arctica, Sminthea arctica, Bathykorus bouilloni, Aglantha digitale. Photos: HYPNO

Loved or hated, jellyfish are the kind of animals that either mesmerize beachgoers or make them go straight out of the water. Fortunately, all participants at the JESS Workshop belonged to the first category of people, and we had a very nice and productive meeting discussing methods, state-of-the-art, challenges, and opportunities of working with jellyfish in Arctic waters.

Happy jellyfish hunters in Tromsø

The workshop covered sessions on sampling, data management, ecology, and diversity, including an interesting discussion on how to obtain more (and better quality) jellyfish data from current plankton monitoring protocols. It was an international meeting (20 participants from more than 10 different countries) neatly organized by the University of Tromsø, but it still felt a lot like a bunch of friends getting together to talk about one fascinating subject, which is something I really enjoyed.

Sampling protocols and data curation were some of the most discussed topics during the JESS Workshop. Photos: Joan J. Soto Àngel

All that talking about feeding and predation made us hungry!

While the JESS Workshop was not exactly held on November 3rd, the spirit of commemoration of our gelatinous neighbors was present during the entire event. Celebrating World Jellyfish Day may be a rather recent activity (I could not find any reference of the first time this date was observed, but most likely it only started a couple of years ago), but being fascinated by the movement, color and shapes of jellyfish is certainly not a new thing. There has always been a lot of mystery surrounding the gelatinous inhabitants of the sea, so in a way it was only natural for the origin of the date dedicated to jellyfish to be as much of an enigma as the animals themselves. Mysterious or not, don’t miss the chance to celebrate your local jellies today!

Acknowledgements
Aino Hosia and Sanna Majaneva did a superb job organizing the JESS Workshop and making us feel at home in Tromsø: thank you so much for that! Many thanks as well to all the participants and speakers for the motivating talks and discussions.

Further reading
What could be better than adding some jelly-related reading to the celebration of World Jellyfish Day? I personally love the classics, so I would always recommend Sir Arthur Conan Doyle’s “The Adventure of the Lion’s Mane” for a case of a peculiar encounter with the beautiful Cyanea capillata. Enjoy!

Teaching DNA barcoding in Siberia

Endre, Katrine, Nataliya and Tom have recently been on a journey far removed from the ocean – although the location did hold a lot of fresh water…!

It really does look and feel a lot like an ocean…

We have – together with Torbjørn Ekrem from the NTNU University Museum – been teaching DNA barcoding at the Russian-Norwegian course “Data mobilization skills: training on mobilizing biodiversity data using GBIF and BOLD tools”, which was held in Naratey on the western shore of Lake Baikal September 14-20, 2018!

The course consisted of two modules focusing on GBIF and BOLD tools. The GBIF part was taught by Dag Endresen from UiO, Laura Russell and Dmitry Schigel from the GBIF Secretariat.

It included both online preparatory work for the students and (mainly) onsite components. The online portion consisted of tasks that the students completed on GBIF’s eLearning portal.

The onsite work was comprised of 20 different sessions of lectures and practical exercises, the latter with a significant component of group work.

16 students from Norwegian and Russian intuitions participated, and did a wonderful job of assimilating a lot of information in a short amount of time, and turning it into practical skills.

The two main platforms we used were GBIF and BOLD – two large depositories for different kinds of biodiversity data. The GBIF-part of the course focused on the technical aspects of data mobilization, such as data capture, and management and online publishing of biodiversity data in order to increase the amount, richness and quality of data published through the GBIF network.

BOLD; Barcode of Life Data Systems

The barcoding part was aimed at both users and providers of barcoding data, and began with an introduction to the barcoding concept, and a case study of integrating data from BOLD and GBIF. This was followed by a session on the use of BOLD: creating projects and datasets, and the uploading of data, images, sequences and trace files. The students got to try all of this for themselves, and we were impressed by how well they worked together to find solutions and teach each other valuable tricks to solve the challenges.

Following the lessons on how to get sequence data into the database, we covered basics of sequence analysis, and gave an introduction to the free software MEGA X which can be used for sequence alignment, translation and phylogeny.

This was again followed by a practical session in MEGA on a given data set. We also had a session presenting the analytical tools in BOLD, with a practical session exploring a dataset from NTNU. Our lessons were very well received by the students, with an average score of 4.8 out of a possible 5 on the evaluations – nice feedback for the teachers!

The final task for the students was to present their presentations for “The Baikal Biodiversity Challenge”, which they were presented with on the first day of the course.

The Baikal Biodiversity Challenge

The challenge was to develop a biodiversity inventory project to map and analyze the diversity of a selected animal group. To do so they would need to use available information in BOLD, GBIF and other sources to examine what was known and identify information that was missing, and come up with suggestions on how it could be solved. It was not the easiest of tasks, however all four groups gave excellent presentations.

The course was arranged as collaboration between the University of Bergen, the Siberian Institute of Plant Physiology and Biochemistry Russian Academy of Sciences (SIPPB SB RAS), the Global Biodiversity Information Facility (GBIF) Secretariat. NorBOL (Norwegian Barcode of Life) supplied the teachers for the barcoding part of the programme, namely Endre, Torbjørn, Katrine and Tom. Funding came from the Norwegian Centre for International Cooperation in Education (previously SIU, now DIKU), GBIF and the Research School in Biosystematics (ForBio).

For those who might not know, ForBio is a teaching and research initiative coordinated by the Natural History Museum in Oslo, the University Museum of Bergen, the Tromsø University Museum and the NTNU University Museum. It is funded by the Norwegian Taxonomy Initiative and the Research Council of Norway. The Research School offers a wide variety of both practical and theoretical courses in biosystematics, and provides a platform for facilitating teaching and research collaboration between Nordic research institutes.  The course portfolio is likely to have something of interest to offer if you work with anything related to biosystematics –and is open (and often free) to you if you are student, researcher or staff at universities, institutes and consulting companies.

Most of the ForBio courses are arranged in Norway or other Nordic countries – but this course was the second of a total six that are arranged as part of the SIU-funded MEDUSA*-project (Multidisciplinary EDUcation and reSearch in mArine biology in Norway and Russia), which is coordinated by Nataliya. The six courses are

  1. ForBio and DLN course: Comparative Morphology Methods (Trondheim, Norway 2018)
  2. Data mobilization skills: training on mobilizing biodiversity data using GBIF and BOLD tools (Siberia, Russia 2018)
  3. Zooplankton communities – taxonomy and methods (Espegrend Marine Biological Station, UiB, Norway, tentatively May 2019)
  4. Systematics, Morphology and Evolution of Marine Mollusks (Vostok Marine Research Station, Institute of Marine Biology, Vladivostok, Russia, September 2019)
  5. Systematics, Morphology and Evolution of Marine Annelids (Espegrend Marine Biological Station, UiB, Norway, tentatively June 2020)
  6. Diversity and Evolution of Meiobenthos (White Sea Biological Station, Moscow State University, Russia, September 2020)

We enjoyed the opportunity to visit such a remote locality, and to get to know the students and teachers – thank you all for making this such a wonderful experience!

Thanks also to the BOLD support team for excellent help before and during the course!

Exposing the Indian Ocean staggering diversity: fieldtrip to Nuarro, northern Mozambique (October 2017)

Pursuing our goal to understand the diversity, origin and biogeography of the Indo-West Pacific biota, we went back to Mozambique to continue the exploration of the reef systems of the country. After a first fieldtrip to the subtropical southern coast of Mozambique in 2014, and a second during 2015 to the tropical Quirimbas islands (Vamizi I.) not far from the border with Tanzania, we visited this time for two weeks between the 15–28 October 2017 the coastal pristine reefs and mangroves of Memba District in Nuarro, Nangata Bay, together with Prof. João Macuio from the University Lurio, Pemba and Dr Yara Tibiriça based at Nuarro Lodge, that kindly organized the expedition.

The staggering diversity of the tropical Indo-Pacific is well known and the area between the Philippines, Indonesia, and New Guinea (the Coral Triangle) is famous for hosting the highest marine diversity in the planet. However, for various reasons (political, economic, etc.) the Indian Ocean has been comparatively less surveyed, and much fewer studies are available for this region. Some recent publications are though showing that for corals and molluscs, at least, the region is extremely diverse, nearly comparable with the coral triangle.

We want to understand why is this region so diverse and whether the Indian Ocean harbours similar or a different faunal composition compared to the West Pacific Ocean. The traditional view is that most tropical species are broadly distributed across the Indo-West Pacific, but recent evidence from DNA studies suggests otherwise, but this is not yet well understood. If significant differences are found, then, understanding what may have driven speciation across both realms becomes a major quest.

Nuarro is a remote place, four and half hours driving from Nampula international airport, half of them through earth roads. It is located in beautiful Nangata Bay lined by fine white sands and calm turquoise waters. The area is characterized by a large diversity of marine habitats like sand flats, coral bommies, seagrass meadows, coral reefs, and coralline drop-off walls plunging into the deep blue.

The expedition had its basecamp at Nuarro Lodge, an eco-lodge offering diving facilities and a research center. The lodge besides its hostel activities is engaged in social, educational, heath, and nature conservation programmes with the local communities helping to improve education standards for the younger generations, mitigate the impact of native diseases like malaria, and the sustainable use of nature resources. For this last goal a marine protected area was created in 2008.

During two weeks we have surveyed the area for marine molluscs (sea slugs) and studied the impact of the marine protected area in the conservation of the highly sensitive and threatened giant clams (Tridacna spp.). The days at Nuarro began early, around 5.30–6am, with the sun already out and high in the blue sky. Waking up was not difficult, with the awesome strident ensemble of sounds from the many local different birds and the monkeys running and jumping on the thatched roofs of our housing! First sampling of the day around 8.30am, followed by a second one after lunchtime. The evenings were dedicated to study, photograph, identify, and database the catch of the day. We have collected approximately 68 species of sea slugs; 11 are new records to Mozambique and an additional 12 still undescribed. The conservation status of the populations of giant-clams was evaluated in areas under fishing pressure by the local communities and inside the marine reserve for comparison, and it was obvious the positive impact of the marine protect area.

The days were busy and went far too fast, but there was time for a short social programme where we paid a visit to the local village and visited the primary school built by the lodge and met a group of local activists that work with the community to raise awareness for issues concerning hygiene, malaria, and other health matters, which regrettably still claim lives in the region far beyond acceptable numbers on the XXI century. Before the trip to Nuarro I was challenged to take a football ball with me for the local team. I have obviously eagerly done it, and it was a great delight to the see the joy of the players of the “Real Nangata” playing around with their new ball!

The Nuarro expedition would not have been possible without the gratitude and support of the Nuarro Eco-Lodge to which I am deeply indebted.  I am also thankful to Prof. Isabel Silva from the University Lurio, Pemba and to the Fisheries Department of the Cabo Delgado Province from granting collecting and exporting permits.

Update from the Annelida-course

20170609_100827

As told last week, we are currently hosting the international course on Annelid Systematics, Morphology and Evolution at the University of Bergen’s field station. Here’s a little update of what we have been up to since the previous post:

The days are pretty packed, with lectures, sampling, and lab work – thankfully both students and teachers are enjoying the work, and the mood in the lab is sunny (even if the Bergen “summer” is somewhat…fickle these days). We have covered a multitude of research topics, methods,  habitats, and annelid groups so far, with still more to come.

Happy, hard working  students in the lab

International Course on Annelid Systematics, Morphology and Evolution

The two-week long International Course on Annelid Systematics, Morphology and Evolution is up and running at the Espegrend Marine Biological Station!

The course is held by the University Museum of Bergen in cooperation with the Moscow State University and ForBio (Research School in Biosystematics). It is sponsored by SPIRE (Strategic Programme for International Research and Education) and SIU (Norwegian Centre for International Cooperation in Education). More info about the course can be found here.

Twenty students and eighteen course organizers and instructors from Norway, Russia and 10 more countries are participating in the course, which is being held in the University of Bergen’s marine research station at Espegrend.

We have been samplingwith both R/V Hans Brattstrøm and the smaller boat Aurelia in several benthic biotopes in the vicinity of the station, and have collected plenty of serpulids and siboglinids among other worm families.

The first laboratory session focused on Sabellida and Siboglinidae and were taught by Maria Capa (NTNU), Nadya Rimskaya-Korsakova (MSU) and Glafira Kolbasova (MSU). Nadya has brought few large vestimentiferans from the Moscow collection and the students got the opportunity to look at famous hydrothermal vent tubeworms.

AmphipodThursday: IceAGE-amphipods in the Polish woods

img_2610This adventure started 26 years ago, when two Norwegian benthos researchers (Torleiv Brattegard from University of Bergen and Jon-Arne Sneli from the University in Trondheim) teamed up with three Icelandic benthos specialists (Jörundur Svavarsson and Guðmundur V. Helgasson from University of Iceland and Guðmundur Guðmundsson from the Natural History Museum of Iceland) to study the seas surrounding the volcanic home of the Nordic sages. 19 cruises and 13 years later – and not least lots of exciting scientific findings and results the BioICE program was finished.

But science never stops. New methods are developed and old methods are improved – and the samples that were stored in formalin during the BioICE project can not be used easily for any genetic studies. They are, however, very good for examinations of the morphology of the many invertebrate species that were collected, and they are still a source of much interesting science.

The dream about samples that could be DNA-barcoded (and possibly examined further with molecular methods) lead to a new project being formed – IceAGE. A large inernational collaboration of scientists organised by researchers from the University of Hamburg (and still including researchers from both the University of Iceland and the University of Bergen) have been on two cruises (2011 and 2013) so far – and there is already lots of material to look at!


This week many of the researchers connected with the IceAGE project have gathered in Spała in Poland – at a researchstation in woods that are rumoured to be inhabited by bison and beavers (we didn´t see any, but we have seen the results of the beavers work). Some of us have discussed theories and technical stuff for the papers and reports that are to come from the project, and then there are “the coolest gang” – the amphipodologists. 10 scientists of this special “species” have gathered in two small labs in the field-station, and we have sorted and identified amphipods into the wee hours.

It is both fun and educational to work together. Everybody have their special families they like best, and little tricks to identify the difficult taxa, and so there is always somebody to ask when you don´t find out what you are looking at. Between the stories about amphipod-friends and old times we have friendly fights about who can eat the most chocolate, and we build dreams about the perfect amphipodologist holiday. Every now and then somebody will say “come look at this amazing amphipod I have under my scope now!” – we have all been treated to species we have never seen before, but maybe read about. We also have a box of those special amphipods – the “possibly a new species”- tubes. When there is a nice sample to examine, you might hear one of the amphipodologist hum a happy song, and when the sample is all amphipods but no legs or antennae (this can happen to samples stored in ethanol – they become brittle) you might hear frustrated “hrmpfing” before the chocolate is raided.

The samples from IceAGE are all stored in ethanol. This is done to preserve the DNA for molecular studies – studies that can give us new and exciting results to questions we have thought about for a long time, and to questions we maybe didn´t even know we needed asking. We can test if what looks like the same species really is the same species, and we can find out more about the biogeography of the different species and communities.

The geographical area covered by IceAGE borders to the geographical area covered by NorAmph and NorBOL, and it makes great sense to collaborate. This summer we will start with comparing DNA-barcodes of amphipods from the family Eusiridae from IceAGE and NorAmph. They are as good a starting-point as any, and they are beautiful (Eusirus holmii was described in the norwegian blog last summer).


Happy easter from all the amphiods and amphipodologists!

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.

Screenshot from WoRMS-search: Andaniopsis lupus

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…

Screenshot from World Amphipoda Database

Screenshot from World Amphipoda Database

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.

Guest researchers: Mario

We started early with visitors for 2016; Mario arrived already on the 4th of January!

Another of our polychaete collaborators, Arne Nygren from Sjöfartsmuseet Akvariet in Gothenburg (Artsprosjekt can be found here (NO)) seized the chance to visit as well, and together with the resident polychaetologists (Jon, Tom and Nataliya) it meant that we suddenly had an impromptu polychaete workshop on our hands 🙂

Being able to meet in person makes the work flow smoother all around, as work was delegated and plans concretized. 2016 is likely to be a year with much focus on the Polychaeta, as it is both the final year of the PolyNor project (ends in spring), and the year of the 12th International Polychaete Conference, which will be held in Cardiff, Wales.

 

During Mario’s month-long stay he was examining the collection of terebellids from West Africa and the museum’s collection of the bristle worm genus Pista, much of which will later be barcoded through NorBOL (for the Norwegian material) and MIWA (for our West African samples).

In his own words:

I usually work on the morphology of just one of the several families of polychaetes, the Terebellidae, or spaghetti worms. This visit has been very important since we have been able to separate four Pista species from the North Sea, using both morphological and molecular tools. “The combination of these two different methods has been superb”.

Jon, Arne and I began this study during August 2014, but this undertaking seems like it will never end because we keep adding more material. The recent findings have been the significance of some characters that did not have taxonomical importance in the past. Now, they are the clues for splitting very close species.

But this is not enough; it was possible to identify 43 species of terebellids belonging to 16 different genera, from material collected along the West African coasts.

This is a high polychaete diversity in only one family. For example, we found three Lysilla species, in a region with only one recorded species. New species? Highly possible. One can only wonder what the diversity of the remaining families is?

All this was accompanied with a perfect view through the window, seeing it snow some days, or watching the Sun on the mountains in front; some times with white top mountains, some times with deep blue sky. A landscape like that never could be my company in my tropical city.
