Door #7: New shipment of tissue samples for barcoding

In the upper right corner is a “plate”: the microplates with 96 wells where we deposit small tissue samples that are to be processed at the CCDB lab in Canada for NorBOL

On the third day of Christmas,
we sent eleven microplates away:
one plate cnidarians (A)
two with worms a-wriggle (B)
two plates of insects (C)
three plates crustaceans (D)
two (and a half) plates of mites (E)
and a half-plate assorted a-arthropods (F)!

Ahem. Yes.

As Endre explained in the fifth post of the calendar, collecting, identifying, documenting and keeping specimens used for DNA barcoding is an important part of what we do here at the invertebrate collections. Our mission in the NORBOL consortium is to produce DNA-barcodes, particularly for marine fauna in Norwegian waters and to make these barcodes available with open access to records and metadata in the BOLD database. These samples contribute to the building of a validated reference library of the genetic barcodes of the species found in Norway. You can search for different taxonomic groups here to see if they have been barcoded from Norwegian territory: Search NorBOL

The process is fairly straight forward (at least on paper!): Animals are collected and identified. Those species relevant for barcoding are selected, and a specimen (=1 animal) is chosen to be barcoded. We take a small tissue sample from the specimen, and keep the rest of the animal as the barcode voucher; if the need should arise to check if it really is what we initially thought, it is crucial to be able to go back and check the animal again. The tissue samples are collected in wells on a plate like the one pictured above, and the information about the animals – where they were collected, who collected them, what species they are, who identified them and so on is uploaded to BOLD together with images of the animals.

On Monday we shipped a new batch of plates – as (attempted) illustrated in song above.

Included is material from several of the Norwegian Taxonomy Initiative projects (artsprosjekt) that are happening at the University Museum of Bergen. We are coordinating the efforts on marine life, but are of course also facilitating the NorBOL barcoding of other organisms that take place at the UMB.  There are animals from NorAmph (Norwegian Amphipoda), Hydrozoan pelagic diversity in Norway (HYPNO), Orbatid mites, and the insects found associated with nutrient rich marshes in Hedmark in this shipment.

We have also prepared several plates of Crustaceans collected and identified by the Norwegian marine mapping programme Mareano – one of the great contributors of material to the collections.

Now we wait for the lab to process them, and for the genetic sequences to be uploaded to BOLD – fingers crossed for many interesting results!

Door # 6: The key to the question

We often say that without knowing the species you examine, you really can’t know a lot about whatever it is you are examining. But how do you get from knowing for example “this is an amphipod” to knowing “this is Amphilochoides serratipes”?

Three different Amphilochidae from Iceland

Most researchers would usually stop at the “this is an amphipod”-stage, and many specialists  would call it a day at “this amphipod belongs to the familily Amphilochidae”. but then there are the one or two researchers who have gone on to specialise in this family (I think there are three of us in the world at the moment).

But finally – those days are over!
As a special gift on this Nicholaus-day when all German colleagues get a special gift from St Nicholaus (who is Father Christmas) we present to all of you – regardless of nationality or faith:

The interactive and illustrated key to the NorthEast Atlantic species of Amphilochidae

The key is a product of a collaboration between the NorAmph-project and the German-lead IceAGE project that examines benthic animals around Iceland, and the technical production and web-hosting of the key is from the Norwegian Taxonomy Initiative (Artsprosjekt) (who – we have to say – also have financed the NorAmph-project!) Hurrah for a great collaboration!

Figure 14 from Tandberg et al

You might still wonder what an Amphilochid amphipod is?

The family Amphilochidae are amphipods that are quite small (1-6mm in length) and quite stout. They are not extremely good swimmers, though much of that can be from their small size – and from their short appendages. They can be found all over the world, and are common at many depths in our cold waters. Even though they are small and easily overlooked, they sometimes occur in relatively large numbers, and can contribute significantly to both the biomass and diversity of a sample. They have been found on hydrothermal vents at the southern part of the Mid-Atlantic ridge, and some have been found as loose associates of other invertebrates.

Also – they are quite cute, don’t you think?  Good luck with the identification!

Door #5: DNA-barcoding with BOLD

Much of the activities in our invertebrate collections are dedicated to so-called DNA-barcoding. Our mission in the NORBOL consortium is to produce DNA-barcodes, particularly for marine fauna in Norwegian waters and to make these barcodes available with open access to records and metadata in Boldsystems.com. In the same manner we have also worked to produce DNA-barcodes for marine invertebrates on the West-African continental shelf in a project called we call MIWA.

These QR-codes will take you to maps with plots of specimens that have been barcoded in our projects (or simply click on them. The red dots on the maps are interactive):

The basic idea motivating these activities is very simple in principle. You collect specimens and identify them, preferably to species, take digital photographs, and upload information about collection site and other relevant data to a database (BOLDsystems.org).

The specimen page has a picture and other data about the organism that the DNA sequence (presumably) was produced from (click picture to enlarge).

You take a tissue sample to extract DNA from the specimen and use DNA-sequencing technology to target a special fragment of DNA to read the sequence of nucleotides. The expectation is that this sequence may be unique for the particular species you identified.  If indeed the expectation is fulfilled, you can use that sequence as an unambiguous identifier (“bar-code”) of that species.  You have produced a DNA-barcode!

A sequence page in BOLD contains the DNA-sequence (the barcode), the aminoacid translation of the sequence, and the trace-files from the DNA-sequencing machine.(Click picture to enlarge)

Your barcode should enter a DNA-barcode library so that, with an appropriate web-interface to a powerful computer with a search algorithm that compares similarities, you should be able to search with a second sequence from another individual of the same species and find that it is identical, or at least very similar to the one you produced for the DNA-barcode library.  The benefits are potentially many. One advantage is that you may be able to identify a species although all the morphological characteristics have been lost. For the biologist DNA-barcodes may help to identify juvenile stages of a species or even the stomach contents of a predator or scavenger. For conservation, customs, trade, and food authorities DNA barcodes are a powerful means to monitor resource exploitation and attempts to swindle with species identities or area of origin of  biological products.

DNA-barcoding certainly also contributes to the mapping of species distributions and to survey genetic characteristics of taxa. Perhaps initially somewhat unexpected, it also reveals many problems in taxonomy that call for resolution through closer studies. More about this will follow in other blog posts.

Door #4: PSA: abstract submission for iBOL Conference is open!

For door #4 we are helping spread word about the 8th International Barcode of Life Conference, which will take place in Trondheim, Norway on June 17-20th next year.

Abstract submissions are open until January 15th 2019, so now is the time to start thinking (if you haven’t already).

The previous IBOL conference – the one in Kruger National Park, South Africa – was not just in an amazing location (which it undoubtedly was!), but covered a wide array of interesting topics and wonderful talks, and IBOL2019 is set to follow suit!

Check out the planned session themes and outstanding plenary speakers here.

Door #3: Mollusc hunting around the world

The study of molluscs (malacology) has a long tradition in Norway. Despite the nearly 50,000 species dwelling in the world oceans and seas, a number only barely supersede by the arthropods, new species continue to be discovered and our understanding of the relationships and systematics of molluscs to change.

At the Natural History Museum of Bergen, the study of molluscs is focal, and research is carried out on various aspects of their diversity, morphology, ecology, systematics, evolution, and biogeography, using state of the art methods like DNA barcoding, molecular phylogenetics, and electron microscopy. Understanding the patterns and processes that drive present diversity in the oceans is one of our main goals and our research foci are framed within several “big questions”: How many and how can we differentiate between species? How do species originate in the oceans? Why some regions in the oceans are more diverse than others? Are mechanisms responsible for the patterns of diversity in the deep-sea the same as in shallow ecosystems?

Our quest for answers necessitate the continuous collection of new specimens and the exploration of remote geographies. We conduct regular fieldwork around the world including Norway, through numerous projects and partnerships.

Here are some snapshots from recent fieldwork from Manuel & team:

Working during October 2017 together with Professor João Macuio from the University Lurio (Pemba, Mozambique) in Nangata Bay (Nuarro, Mozambique) on a survey of the sea slug diversity inhabiting this pristine coral reef area and on an assessment of the structure and conservation status of the population of the threatened giant clam species (Tridacna maxima). Left image: Manuel Malaquias and João Macuio photographing sea slugs at the Nuarro Research Center.

Working in remote places requires often some capacity to improvise and during a fieldtrip to Taiwan while in the Penghu islands we had to convince the manager of our hostel to let us set up a field-lab in the garage among his gear and pet-cage!

In the Penghu islands we had the opportunity to work in the field together with students from the National Penghu University of Science and Technology, here depicted in the right image helping collecting sea slugs along a water stream lined by few mangrove bushes.

After a three weeks fieldtrip to Vamizi island in the Quirimbas archipelago, north of Mozambique during May 2015, we were finally brought to shore at Palma village near the border with Tanzania where we had to do some final sorting and organization of samples under the curious eyes of the local villagers (Manuel Malaquias and Yara Tibiriça from the Zavora Marine Lab in Mozambique).

Door #2: A glimpse of Hydrozoan anatomy

Hydroids and hydromedusae are abundant and widespread, but they can be difficult to identify, in part due to the overwhelming amount of terminology used to describe their polyps, colonies and medusae. The diversity of shapes and life cycle strategies in Hydrozoa is in fact so high that it is almost impossible to find a single set of descriptive terms for all species, and different glossaries have been developed for closely related families, sometimes genera, and also for the different stages in the life cycle of the same organism. To further complicate things, the terminology we use for the characterization of hydrozoan morphology has been adapted in many cases from other fields of science (like botany and geometry), and some of the words ended up with very different meanings depending of the organism we are looking at.

But if you are interested in these fascinating creatures, fear not! We at the invertebrate collections have thought about giving you a little visual aid in the form of four plates including some of the basic structures of hydroids and hydromedusa (courtesy of artsprosjekt HYPNO and upcoming artsprosjekt NORHYDRO).

Hopefully these images can be used as a starting point for the uninitiated, and why not? perhaps also as a source of inspiration for cool marine-related presents for the season!

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!

NorBOL and BOLDsystems course Trondheim 17th-19th of October

Travelogue from Cessa Rauch

Today the weekly event of MolluscMonday and the annual SeaSlugDay (29th of October) coincide!Bunch of sea slugs to celebrate sea slug day, collected in Askøy

What better way to celebrate it with another blog! Much has happened again since the last blog in August, in which we went on fieldwork in Askøy by joining the ladies of the jentedykketreff to find sea slug species in the Bergen area. We officially started to barcode our first specimens, got two new master students that will also work on the project by looking into a variety of topics (diversity of sea slugs in Hordaland, population genetics of Polycera quadrilineata and taxonomy of the genus Eubranchus).

In this blog I will share with you how we are uploading our slugs to the World Wide Web with help of the Barcode of Life data system and how the Norwegian Barcode of Life is helping us getting this done by organizing an informative course in Trondheim.

First step in trying to decode our precious species
The sea slugs of Southern Norway project is a two-year project funded by Artsdatabanken (The Norwegian Taxonomy Initiative) with the aim of mapping the biodiversity of sea slugs along the Southern part of the Norwegian coast

Sea slugs of Southern Norway being eaten by Doris pseudoargus

The focal area stretches from Bergen, Hordaland, all the way down to the Swedish border. In May, July and August of this year the project successfully completed its first fieldwork trips with an additional of 500 new registered museum specimens that cover roughly 90 sea slug species. The species names are attributed based on morphological characteristics, but several species exhibit amazing colour polymorphism, possibly hiding cryptic diversity.

Moreover, we cannot discard the possible occurrence of alien species with similar morphotypes to the native fauna. Therefore, we will need to DNA barcode our specimens to either confirm or change the species names credited to our collected specimens. Besides it will give us an overview for the relatedness of the sea slugs to one another and unravel maybe new species!

In order to successfully sequence 500+ specimen the project collaborates with the Norwegian Barcode of Life project (NorBOL). NorBOL is a network of Norwegian biodiversity institutions and individual scientists that coordinates the establishment of a library of DNA sequences (barcodes) of the fauna and flora of Norway. These barcodes)will be submitted to the open access database BOLD (Barcode of Life Data System), as part of the global Barcode of Life initiative and the International Barcode of Life project (iBOL).

Barcode of Life Data System course
Barcode of Life Data System (BOLD) is a globally orientated online workbench and database that supports the assembly and use of DNA barcode data, and is open access to the scientific community and public. At the moment it holds a record of 6235000 barcodes; 194000 of those are animal species, 67000 plant species and 21000 fungi and other species. The BOLD system is an amazing tool to work with for those interested in biodiversity research. Initially it can be a little overwhelming to fill in all available data into Excel file after Excel file, as this is mandatory and needs to be uploaded first to the system before any sequencing can be done. Especially for those who have many specimens to work with. But afterwards the reward is very fulfilling as you, in an instant, can see distribution maps, trees and images of all the specimens uploaded.

Image library of all the collected sea slugs

It is the perfect tool for digitizing, analysing, storing and accessing your genetic and image library data from everywhere anytime. BOLD system standards for uploading actual specimen data are pretty high, the quality of what you can find on the platform is good, but in order to keep these standards great, NorBOL organizes special multi day courses for users in order to guide them through all the steps and features of the BOLD system. This year the course was organized by the NorBOL National coordinator NTNU in Trondheim.

It would take three full days of getting together with fellow participants and going through all the steps necessary in order to start a successful project in the BOLD platform. This year it took place from 17th till 19th of October and as such, me, Anna and Per travelled that Wednesday the 17th very early in the morning to Trondheim. The course was well attended with participants traveling from all over Norway and even from its neighbouring country Sweden. The first day consisted mainly of introduction talks and familiarizing ourselves with the many new abbreviations; NorBOL, BOLD, iBOL (et cetera).

It was a nice experience to meet and talk to other biologists working on such interesting topics, varying from flies, mites, sponges, jellyfish, worms, variety of plants, etc. Everything was taken care off, we could check in to our hotels and in the evening, we had a dinner together with the organizers and participants. The next two course days we were asked to work with our own brought specimens. The days consisted of registering the specimens, filling in as much data per specimens as possible. After finishing and uploading the first datasets, it was time to make pictures of every species, before sampling them for DNA barcoding tissue. Almost all participants brought a 96 wells plate worth of specimens so you can imagine the work that was put into getting everything finished in such a short amount of time.

The course was an excellent way to get used to the different steps necessary in order to make the submission process a success. And it was very helpful that at any given moment we could ask the course organizers for advice during the preparations of the datasets and the submission.

All the participants were very excited about the course and happy they attended, it was nice meeting new people and as for someone that moved to Norway, a good opportunity to finally also see Trondheim, with its amazing large Cathedral, a real eyecatcher

 

 

Sea slug goals
The goal for the sea slugs of Southern Norway project is to barcode all, or at least as much as possible, collected specimen, in order to attribute species names to them, expose cryptic species, maybe find new species and look out for invasive and or alien species. Thanks to this course the first 95 species will be barcoded soon and be added to the image library that we already managed to set up (Image 8. Screenshot of the project page of sea slugs of Southern Norway in the BOLD system workbench).

We are very much looking forward for the first results to be accessible and to analyse the data; keep an eye on the invertebrate blogs because for sure the follow up of this story is going to be pretty exciting.

Course on “Preparation, curation, and databasing of marine biodiversity collections” at University Lurio, Pemba, Mozambique (27th August–7th September 2018)

Manuel shares his recent experience of teaching at University Lurio in Mozambique

My collaboration with the University Lurio (UniLurio) in northern Mozambique started back in 2015 when together we organized a fieldtrip to Vamizi island in the Quirimbas archipelago off the northern coast of Mozambique.

Since then, I had the opportunity to participate in several academic activities; I lectured, have reviewed and evaluated theses for the “licenciatura” degree, and most rewarding I have supervised two master students (2015/17) that are now professors at UniLurio. In 2017 I had the pleasure to integrate a mission organized by the Norwegian Embassy in Mozambique to establish a collaborative programme between UniLurio and Norway and later in the same year I was awarded a “Visiting Scholarship” by the International Council for Science, Scientific Committee on Oceanic Research (SCOR) to teach a course about biological collections at UniLurio.

The tropical location of Mozambique in the Indian Ocean results in an impressively rich biological diversity which is nevertheless extremely vulnerable to climate change and warming of ocean waters.

Aspect of part of the UniLurio wet spider collection and dry collection of corals

Therefore, better knowledge of biodiversity and long-term preservation of biological collections are important tools to better understand shifts in faunal and flora composition and the arrival of new species supporting the definition of mitigation and conservation strategies.

The University Lurio has a “Collections Room” with specimens representing the local fauna and flora with marine invertebrates, reptiles, fish, vascular plants, etc., and has a special focus on the study of biodiversity, but simultaneously acknowledges the need to reinforce its infrastructure and build up capacities to develop and manage its collections.

 

This was the framework that led us to decide to organize the course and apply together for funding with SCOR. Later in 2017 the good news arrived, the funding was approved, and so, suddenly I had an entire new course to put together!

All my entire career from the time I undertook my “licenciatura” thesis back in 1994 all the way up to my PhD, postdocs, until the moment I got my first permanent job (the one I still hold) has been always inside natural history museums (Europe, US, Australia, etc.) and consequently working with biological collections has become part of my daily routines for quite a while! And yes, during these more than 20 years I have seen quite a bit and learn a few things, but suddenly for the first time I had to put together this knowledge in a way that it could be presented and shared with others. It turned out to be quite a challenge…, but definitely a rewarding one!

Course structure

During a lecture on curatorial procedures

Photoshoot before setting off for sampling in a local Pemba tidal flat

At UniLurio the course was attended by 15 participants (8 students and 7 professors / technical staff). It was organized in four lectures (2h each), two sampling trips (ca. 4h each) to the tidal zone to collect marine invertebrates (molluscs, echinoderms, crustaceans, etc.), and three laboratory sessions (4h each) to identify the samples and go through all the necessary curatorial steps to ensure proper preservation for long-term storage of the collection (relaxation, fixation, preservation, DNA samples, registration, labeling).

Registering and labelling the lots

All sample lots generated by the students throughout the course were registered in the UniLurio databasing system following DarwinCore standards and at the end integrated in the biological collections.

Bringing the new curated samples to the UniLurio collection room

We finished the course with a very participated open session where it was discussed how could the new acquired competences benefit the development of the local infrastructure bearing in mind the local reality and constrains. A very interesting exercise confronting ideal scenarios with sometimes the harsh and challenging reality of a country with limited infrastructure capacities and in economical strain. At last we had a simple but cozy ceremony attended by the Director of the Faculty of Natural Sciences, UniLurio where certificates of attendance of the course were handed over to the students.

The course was sponsored by the International Council for Science, Scientific Committee on Oceanic Research (SCOR), the University Lurio, Mozambique and the University of Bergen, Norway
