Scavengers in the ocean

Most animals are sloppy eaters. They have their favourite piece of food that they go for, and then they leave the rest. This allows for others to pick up where others leave. One of the laws of ecology is that “there is no such thing as an empty ecological niche”. That can be translated to “where there is a food-source (or a place to live) someone or something will use that food-source (or place to live). And that gets us to the sloppy eaters out there, and not least the animals picking up after all the sloppy eaters.

From the pigeons crowding under your cafe-table for your panini-crumbs to the rats in our sewers, our “local scavengers” tend to be animals we feel slightly uncomfortable around. Is it different with the scavengers we dont see so often? It does not seem that way. Vultures  are not the most popular birds, even the word “vulture” has a negative connotation – and we mainly use it in its non-bird meaning.

How about the scavengers of the sea? As on land, we have many different animal-groups that can be classified as scavengers. Many of the marine scavengers are invertebrates (even if some fishes also scavenge). Let us look at the scavenging Lysianassoid amphipods. Are these as little loved in our world as the rats and vultures seem to be?

Lysianassoid amphipods can mostly be distinguished from other amphipods by their “telescope-like” antennae: a very fat inner article with the two next looking like a collapsed old fashioned radio-antenna; two short rings. We know that the antennae of crustaceans are often used to “smell” things in the water – food or mates or possibly even enemies. It is not thought that the radio-antenna-shape of the Lysianassoid antenna specifically has to do with being a scavenger, as other amphipods and indeed several other crustaceans not having such an antenna are also scavengers. But most Lysianassoids have that antennae, and it makes for an easy first-sorting for the scientist. (Getting further – towards a genus, or even species name on the other hand, is not so easy).

Other general traits in most Lysianassoids, are the smooth exterior, and their high swimming abilities. Both are good if you need to get to some leftover food-source fast, and to “dive” into the food-source while not getting stuck through the entry.

And this is where many Lysianassoids loose out when it comes to human appreciation. They seem to love to scavenge on fish caught in fishnets and traps, and both professional and hobby fishers don’t like to share their catch. We dont think it is very appetising to find our fish-dinner “infested” by non-fish. I am quite sure the scavengers being pulled up with their lovely find of dead or dying fish also are not pleased with having to share their dinner with us.

Lysianassoid scavenging amphipods are the focus of our NBIC-financed project NorAmph2. Here, we will collect and register what different species are present in Norway, and we will try to barcode them. These are quite tricky animals to identify properly, but luckily we have teamed up with the best lysianassoid-expert we know – Tammy Horton from the National Oceanography Centre in Southampton, UK.

We use baited traps to collect: put some lovely, smelly fish out there and see who comes to dine. So far, we have collected from Svalbard in the north to Kong Haakon VIIs Hav in the south, and from the intertidal to the deep. They are often many, and the size-variation is great. We look forward to continuing finding out what species we have, and to see if what morphologically seems one species really is (only) one species genetically. (This previous blog-post (in Norwegian) tells the story about one scavenging amphipod that turned out to be 15 (or maybe even more!) separate species)

Sea slugs of Southern Norway; farewell but not goodbye!

A note from the Norwegian Taxonomy Initiative project (artsprosjekt) “Sea Slugs of Southern Norway” (project home page), which ran from 2018 to the end of April 2020.

Dear all,

The Sea slugs of Southern Norway project reached its terminus at the end of April, with sending the last reports of our collection and research efforts to Artsdatabanken (the Norwegian Biodiversity Information Centre).

What we have been able to build up these last two years is of immense importance for the scientific collections of the Natural History Museum of Bergen (University of Bergen)  and for (Norwegian) biodiversity research.

Sea slugs of Southern Norway managed to collect over 1000 lots covering 93 different sea slug species, of which 19 are new for Norway and a few new to science (we are working on it!).

Below are photos of the species that were collected at different sampling events.  The photos are made either by the researchers associated with the project, or by the amazing team of citizen scientists.

Look at these beauties!

This would absolutely not have been possible without the special effort of our knowledgeable citizen scientists, and we would like to use this opportunity to name a few that were extraordinarily productive during the last years and provided the project and the Museum with valuable samples; Nils Aukan, Roy Dahl, Viktor Grøtan, Heine Jensen, Tine Kinn Kvamme, Runa Lutnæs, Ole Christian Meldahl, Jenny Neuhaus, Bjørnar Nygård, Anders Schouw, Erling Svensen, Cecilie Sørensen, Mona Susanne Tetlie, Anne Mari with Ottesen, Mandal Dykkerklub, Hemne Dykkerklubb, Slettaa Dykkerklubb, SUB-Studentes Undervannsklubb Bergen, Larvik Dykkerklubb, Sandefjord Dykkerklubb, and all the others that made big and small contributions.

A big thank-you to all contributors!

Would you like to know more about the citizen scientists part of the project? Check out this paper (starts on page 23) by Cessa and Manuel: Sea Slugs of Southern Norway: an example of citizens contributing to science.

Mandal team

One of the core components of the projects success was our outreach effort on all kind of social media platforms. During these two years these platforms got much more traffic than we initially thought; apparently we have many Norwegian sea slug fans, within and outside of Norway!

Therefore we decided to continue with our outreach efforts to keep everyone engaged and up to date about these wonderful animals in our ocean backyard, but with some minor adjustments. Some of you might have already noticed a few changes during the last days on the Facebook page  and our Instagram account. From today onward, the social media pages will cover sea slugs of all of Norway, and is now named accordingly. We also welcome a new admin to the facebook group: Torkild Bakken of NTNU University Museum. Welcome Torkild, the more expertise the better, so we are very happy to have you onboard!

We encourage everyone in this community to continue to be active and share your findings and knowledge with other.

Let’s carry on enjoying the wonderful world of sea slugs of Norway!

HYPCOP kickoff!

Follow us at @planetcopepod!

Tuesday may 19 was the first fieldwork of the new project called Hyperbenthic Copepoda (HYPCOP). You can read more about the field work and see some photos and videos from the field in the previous blog post. 

Copepoda are small crustaceans that are found all over the world in both marine and freshwater habitats. Species can be planktonic (drifting in the sea water) or can be parasitic and a large diverse group of them live on algae in the hyperbenthic (living near the bottom) zone. Copepoda are very important food source for many organisms like small fish, they are on the bottom of the food pyramid, together with other zooplankton. Without copepods, a lot of bigger animals would no exists. Despite being so important, not much is known about the biodiversity and taxonomy of these animals, especially that of the species that live near the bottom.Some species like Calanus finmarchicus are the main nutritional basis for many fish species, and therefore of great importance for the Norwegian fish strains.  Therefore Artsdatabanken is funding the new project HYPCOP in order to unravel the biodiversity and taxonomy of hyperbenthos copepods. With special focus on the species in the group Harpacticoida that live in the water masses just above or near the bottom. Copepods from shallow water will be collected in coastal areas, in deep fjords and on the continental shelf.

The Institute of Marine Research (IMR), Natural history museum of Bergen (UiB), Norwegian Institute for water research (NIVA) and the Norwegian Barcode of Life (NorBoL) are working together to survey the diversity of marine copepods in Norwegian waters and expect to find and describe species that are new to science and new for Norway! Currently some of the taxonomic competence in Norway is lacking, but through collaboration with foreign experts this knowledge will increase among Norwegian researchers and students!

The projects duration will run from 2020 until 2023 and last week was the official kickoff with some fieldwork to get fresh material to work with! Together with the project Hardbunnsfauna we drove to a local favorite collection site of us; Biskopshavn; very close to Bergen city center. Around the hard substrate we found lots of freshly grown algae that contained many small animals for us to collect! In order to get good quality samples we needed to be in the water and snorkel. With plankton nets we collected algae and sieved the water column catching the smallest of the animals; copepods!

And even though this was just a first test of equipment and collection methods, it was not without success. Back in the lab the microscope revealed the beautiful and diverse world one drop of seawater contains. A lot off small crustaceans and of course the copepods were omnipresent.

Our findings had to be shared and especially for #InternationalDayForBiologicalDiversity the copepods cannot be left out as they from such an important group! See for yourself the beauty of our copepod planet!

Field work in Biskopshavn

Happy International Day for Biological Diversity 2020!
On this day, we wanted to share a few glimpses of our most recent field work:

We were finally able to – with some precautions in place – resume our field activities again this Tuesday; we had a lovely day trip in the sun to Biskopshavn, a locality just a few minutes drive away from the lab.

Here we collected animals from the shallow sub-littoral (from just below the tide mark to ~3 m depth) for the new project on Copepoda (see more about that here), and for Invertebrate fauna of marine rocky shallow-water habitats (Hardbunnsfauna).

Below is a short video from the field & lab (including the inevitable Littorina on the lam!), and a few of our findings from the day.

This is a polychaete in the family Syllidae. If you look at the tail end on the top image, you can see that it is about to breed: these animals can do so with schizogamy, which is the production of stolons (enlarged in lower image) which are budded off and become pelagic, swimming away to breed. The stolons form complete new animals, but differ from the stock animal in a number of respects, such enlargement of the eyes, reduction of the gut, and different musculature. The stolons die after breeding.

One of the animal groups Hardbunnsfauna is focusing on is the Bryozoa, or moss animals. Pictured is a Bowebankia spp. Due to COVID we haven’t been able to host our international specialists here this spring. We are amassing a nice collection of animals, and do our best to identify them – we will  begin preparing plates for DNA barcoding soon, and then involve the taxonomists once we have the results.

Meet ZMBN 130407!

How much information do you think we have on the animals in our collections? 🤔

Quite a lot more than you might think, and here to help us show you, we have a small snail from the shore. Meet specimen #ZMBN 130407, a Littorina saxatilis 🐌 (rough periwinkle/spiss strandsnegl).

We collected it one year ago on our fieldwork up North, in Tendringsvika near Tjeldsund (Troms): our northernmost station on the trip.

Tendringsvika in Troms

Here’s a short video of the habitat: notice how the sea urchins dominate once we get below the intertidal zone!

To be able to use the Invertebrate Collections for research, we need to know quite a lot about each animal (“specimen”). Standard information would be where, when and how it was collected, who collected it, who identified it (and revisions), notes about the habitat, images if any, and the museum number that it is registered within our database.

A screenshot of how it may look when a specimen is registered in our database

If there is genetic data – like here, a DNA barcode as part of NorBOL – we also need the genetic information. This information is stored in the international barcode library BOLD (BOLDSystems.org), where it is organised in projects containing information linked to the physical specimen, and to the DNA.

Small snail, much data!

If you look at the lower right corner, you will find information about specimens that have identical DNA sequences, and who are therefore grouped together in what is called a BIN in BOLD (/OTU). Most of the other specimens with identical DNA barcode have also been identified to Littorina saxatilis, but not all…that’s one reason to keep the animals in museum collections, so that identifications can be re-checked if needed 🔬.

Through our project (hardbunnsfauna) on shallow water hard bottom fauna from Norway, we are helping build a good DNA barcode library of species that occur in Norway – with reference (“voucher”) specimens in the scientific collections of the University Museum of Bergen, and with our partner, NTNU University Museum.

Science Communication – Creating Scientific Illustrations

What on earth is this going to become?

I (Katrine) recently attended a course on how we can use illustrations to (better) communicate our science.

The course was offered as a joint effort of four Norwegian research schools: CHESS, DEEP, ForBio and IBA, and I got my spot through ForBio (Research School in Biosystematics).

The course was taught by Pina Kingman, and covered a lot of different topics in four days, from messy drawing with charcoal to using graphic software for digital illustrations:

  • Principles of design and visual communication
  • How to apply these principles to illustration and graphic design, which in turn will inform all visual material you might want to create, including; graphical abstracts, presentation slides, poster presentations, journal articles, graphs, data visualisation, project logos, animations and outreach material.
  • Best practices for poster and slide presentation design
  • Step by step method on how to draw your own research
  • Introduction to sketching by hand
  • Crash course in digital illustration with mandatory pre-course digital tutorials

Now, we were sternly told on day 1 that we were not allowed to say that we could not draw…but let’s say that some people have more of an affinity for it than I do – see above for proof! None the less, a concept was to be developed, discussed and improved during group work, and ultimately transformed into a digital illustration by the end of day 4.

Most of my fellow students were creating something related to their ongoing research, such as an illustration to be used in a paper of their PhD. On the last day we presented our work for the class, and got the final feedback from the group. Spending a whole day looking at cool graphics and learning about people’s work on such varied topics as water flow in magma, colour patterns on Arctic rays, better diagnosis of tuberculosis, and ecosystem modelling was really enjoyable, and the feedback I got was very helpful.

I opted for an outreach-approach, creating a lot of small illustrations that will be individually useful in future presentations and such, and which could be combined into a small comic about our scientific collections. The comic has been shared on Twitter and Instagram (do follow @hardbunnsfauna!), and now here:

The end product of the course; a short introduction to our scientific collections, how we work, and how we integrate data such as DNA-barcodes and morphological traits of the animals to do our research!

Thank you to Pina, Mandy (& the other arrangers), and the class for a wonderful learning environment and a fun couple of days!

Field season’s end

Sletvik field station, October 15th-23rd 2019

We wanted to make a write-up of the last combined fieldwork/workshop we had in 2019, which was a trip to the marine field station of NTNU, Sletvik in Trøndelag, in late October. From Bergen, Luis (NorHydro), Jon, Tom, and Katrine (Hardbunnsfauna) stuffed a car full of material, microscopes, and drove the ~12 hours up to the field station that we last visited in 2016.Beautiful fall in Trøndelag

There we joined up with Torkild, Aina, Karstein, and Tuva from NTNU university museum, students August and Marte, and Eivind from NIVA. We also had some visitors; Hauk and Stine from Artsdatabanken came by to visit (if you read Norwegian, there’s a feature about it here), and Per Gätzschmann from NTNU UM dropped by for a day to photograph people in the field.

Most of the workshop participants lined up Photo: Hauk Liebe, Artsdatabanken

During a productive week the plan was to work through as much as possible of the material that we and our collaborators had collected from Kristiansand in the South to Svalbard in the North. Some of us went out every day to collect fresh material in the field close to the station.The Artsprosjekts #Sneglebuss, Hardbunnsfauna, NorHydro, and PolyPort gathered at Sletvik, and with that also the University museums of Trondheim and Bergen. Of course we were also collecting for the other projects, and the museum collections.

One of the things Hardbunnsfauna wanted to do whilst in Sletvik was to pick out interesting specimens to submit for DNA barcoding. This means that the animals need to be sorted from the sediment, the specimens identified, and the ones destined to become barcode vouchers must be photographed and tissue sampled, and the data uploaded to the BOLD database. We managed to complete three plates of gastropods, select specimens for one with bivalves, and begin on a plate of echinoderms, as well as sort through and select quite a few crustaceans and ascidians for further study.

Collecting some fresh material was particularly important for NorHydro because the hydroids from the coasts of Trøndelag have not been thoroughly studied in recent years, and therefore we expected some interesting findings in the six sites we managed to sample. We selected over 40 hydrozoan specimens for DNA barcoding, including some common and widespread hydroids (e.g. Dynamena pumila), some locally abundant species (e.g. Sarsia lovenii) and exceptionally rare taxa, such as the northernmost record ever for a crawling medusa (Eleutheria dichotoma). We also used a small plankton net to catch some of the local hydromedusae, and found many baby jellyfish belonging to genus Clytia swimming around the field station.

Plan B when the animals (in this case Leuckartiara octona) won’t cooperate and be documented with the fancy camera; bring out the cell phones!

It was a busy week, but combining several projects, bringing together material spanning all of Norway, and working together like this made it extremely productive!

Thank you  very much to all the participants, and to all the people who have helped us gather material so far!

Sea slugs from Vestfold

Larvik & Sandefjord 22.10.2019 – 27.10.2019

From October 22 to October 27, Sea slugs of Southern Norway crossed the Hardangervidda mountain pass to pay a visit to Larvik Dykkeklubb (LDK) and Sandefjord Dykkeklubb (SDK). Vestfold, in particularly the Larvik area, was a thorn in the side for the sea slug project. With fieldwork and collection trips covering most of the Hordaland area (Bergen, Espegrend), Rogaland (Egersund), Mandal (Vest-Augder), Drøbak (Oslofjord area) a lot was left to be discovered still for Aust-Agder and Vestfold. Therefore, a visit to Vestfold was very high on our bucket list.

With Winter just around the corner, we decided to squeeze in a short fieldwork trip to Larvik just before the end of 2019. Me and Anders Schouw drived from Bergen to Larvik with our rented caddy to meet up with Tine Kinn Kvamme and members of the LDK. On Tuesday morning, after packing our mobile laboratory in the car, we drove off to Larvik. In the early evening we arrived at the LDK, there we were welcomed by Lene Borgersen from LDK, who facilitated access to the clubhouse for sorting sea slugs during our stay. That evening was also a club members evening, and I took that opportunity to give a presentation about sea slugs and the Sea slugs of Southern Norway project

It was a great evening talking about sea slugs with interested club members while eating pizza! The next day Tine, Anders and I met up with LDK member Mikkel Melsom, who joined to help on our hunting for sea slugs

Later that day we met up at the SDK clubhouse with Stein Johan Fongen, where I had the opportunity to once again talk about sea slugs this time to the SDK members. This was a very special evening because among the audience, besides SDK members, we also had students from Sandefjord videregående skole (Sandefjord High School)

In the following days several members of the SDK also joint us collecting sea slugs. Despite the fact that October is known for being not an ideal season to find sea slugs (most species are observed during Winter and (early) Spring) we still somehow ended up with hours of sorting work at the Larvik clubhouse

Overall, we collected 21 different species, all newly registered specimens for the project with regard to this part of the country. It would be great to see what the species abundance would be during a sea slug season like February or March!

Overview of the species collected at Larvik and the Sandefjord area

Besides sea slugs and enthusiastic club members, another highlight of the week was a visiting seal at SDK! On our last day of fieldwork, a young seal was very bold and decided to rest close to the clubhouse in the harbor. It let people come up really close, which was great for making cute seal pictures. Cherry on the cake, in my opinion!

On Sunday the tree of us had to say goodbye, Tine would go back to her hometown Oslo and Anders and I would cross the snowy mountains again back to Bergen. It was a short but sweet visit and great opportunity to meet members of Larvik and Sandefjord dykkerklubbs. I therefore want to thank LDK and SDK for their interest, enthusiasm and help for the few days Anders, Tine and I were around. I surely hope we will meet again next year, and find many more sea slugs. And of course, thanks to Anders and Tine for helping again, hope we can share many more sea slug adventures together

Invertebrates in harbours

Harbours and marinas are interesting places to look for marine creatures. These environments are usually teeming with life, but a closer look often reveals that their communities are strikingly different from the ones living in adjacent natural areas. Piers and pontoons offer new surfaces for many algae and animals to grow, and the maritime traffic of large and small boats allow for an intense movement of organisms, making harbours some of the preferred spots for newcomers (what we called introduced species) to settle. Many surprises can be expected when sampling for invertebrates in these man-made habitats, which is why our artsprosjekt NorHydro teamed up with project PolyPorts (based at the NTNU University Museum) to explore the hidden diversity of worms and hydroids in the Norwegian harbours.

I was very happy to collect polyps in sunny Southern Norway.

Last year, PolyPorts sampled extensively in some of the main Norwegian harbours (including Oslo, Bergen, Trondheim, and Stavanger); but for this year’s sampling season our two projects headed first south (to the harbours and marinas of Sørlandet), and then west (to Bergen).

In the south, we sampled several ports and marinas from Kristiansand to Brevik (including Lillesand, Grimstad, Tvedestrand, and Risør, thus covering a large portion of southern Norway). In Vestlandet we concentrated our efforts in the area of the port of Bergen, Puddefjorden and Laksevåg, as well as Dolvika.

 

Although it could be surprising that heavily trafficked (and sometimes quite polluted) harbours support a high diversity of invertebrates, this was actually the case for every single port we surveyed.

All our sampling areas had pontoon pilings and mooring chains covered in colourful seaweeds and animals, and reefs of native and introduced mussels and oysters that provided a home for sea squirts, skeleton shrimps, bryozoans and hydroids. For NorHydro, perhaps the most surprising result came from the brackish areas that we analyzed, where large populations of Cordylophora caspia were found. This species is not native to Norway and had not been observed in so many Norwegian localities before, making for an interesting finding to explore even further through the analysis of DNA.

Success in the South; fieldwork in Mandal

From May 20th to 27th the sea slugs of Southern Norway team headed South to Mandal to pay a visit to the Mandal dykkerklubb and try to find more enthusiastic citizen scientist to join the sea slug project. We had a few special guests invited for the week and the team consisted of Cessa Rauch, Manuel Malaquias, Anders Schouw, Erling Svensen, Nils Aukan, Tine Kvamme and Heine Jensen. In Mandal the head of the club Erling Tønnessen would be there to help us around and organize club activities for collecting the sea slugs.

The first day basically consisted of traveling to Mandal and setting up our “hyttes” for a week of sea slug hunting. As usual we underestimated the amount of space needed to bring our ‘mobile’ lab to the camping site in Mandal. Even though a station wagon theoretically fit a family of five plus luggage, it was barely enough space for a family of sea slug hunters with their equipment.

Picture 1. We accomplished to fit everything in this rental car, picture Cessa Rauch

We ended up with a challenging Tetris game and me being squeezed between microscopes and jars in the back seat, still, no complaints! At least I was spared for driving the long hours from Bergen all the way to Mandal, that every local would be able to fix in less than 7 hours, we managed to take 12. I guess the car was heavy loaded! Manuel did a fantastic job while Anders and me where dozing off. Eventually we managed to arrive safely in Mandal and there we were greeted by our team of citizen scientists that helped us out through the week. They as well had to travel from all corners of the country; Kristiansund, Egersund, Oslo and Sarpsborg. It was quite special to arrive all together in Mandal with only one thing in our minds; finding sea slugs!

The next days in collaboration with the local Mandal dykkerklub and their fantastic club boat equipped with a lift to get people in and out of the water, we operated most of the sampling activities. After a day out collecting we would all go back to our cabins and start photographing and registering the samples.

Even though late spring is supposedly not the best season for collecting sea slugs, due to low abundance of the different species, together we were still able to collect 47 different species!

Picture 4. Overview of the species collected during fieldwork in Mandal

On our last day of the expedition, the Mandal dykkerklubb organized an evening social gathering for their members in which we had the chance to give a presentation about sea slugs and the project, and to give away a few sea slug sampling kits to all those interested.

Picture 6. Interested dive members of the Mandal dykkerklubb showing up to learn more about sea slugs and having a good time, picture Erling Svensen

With every fieldwork trip we get more experienced in the organization and execution of the event and this is definitely paying off in the diversity of species we manage to collect. We were not able to register so many species before as with this fieldwork trip to Mandal. This was by far the most successful expedition and together with the joined efforts off all the excellent citizen scientist we formed a real professional sea slug team!

At the moment we are waiting for the first DNA barcode results in order to confirm the species diversity we found that week. An update will follow; but Manuel and I would like to take this opportunity to gratefully acknowledge all the efforts and interest of our team members of that week and the good times we had together! Hope to meet you all again soon during yet another sea slug hunt! Tusen takk!
