NELOS divers will now access WoRMS from their digital dive log

NELOS divers

NELOS, the Flemish diving federation, has recently integrated WoRMS (the World Register of Marine Species, supported by LifeWatch Belgium), into its internal platform DIVES: a Digital Verification System used to log tens of thousands of dives each year.

This integration marks a very important achievement, because divers will now be able to record the marine species that they come across during their observations, in direct connection with the WoRMS database!

The WoRMS database provides an authoritative and comprehensive list of names of marine organisms, controlled by taxonomic and thematic experts and continuously updated. Its editorial management system, in fact, includes one expert for each taxonomic group, who controls the quality of each entry. The editors can also invite specialists of smaller groups to revise specific species.

An interesting characteristic of the new integration with DIVES, is that the platform adapts to common marine species names used in Dutch, and through a built-in search function, it automatically provides the scientifically correct version of the name.

This integration has a great potential to support future research by becoming a valuable data source, supporting citizen science and marine biodiversity through simple digital tools.

Weever fish sevenfold increase reported by SeaWatch-B might be linked to warmer waters

weever fish

SeaWatch-B (https://www.vliz.be/projects/seawatch-b), the VLIZ citizen science project supported by LifeWatch Belgium, has observed that the weever fish counts were seven times higher this year, compared to the same period of time (April to June) of 2024. This venomous species buries itself in the sand and stings through its dorsal or gill-cover spines, and its surge along the Belgian North Sea coast seems linked to warmer waters.

The aim of the SeaWatch-B beach observation network is to address the lack of reliable long-term data that allow to identify trends in the ever changing landscape of the North Sea. In fact, during the last 50 years, the North Sea has noticeably changed, warming twice as fast as the global average for ocean and seas.

This fast change has affected especially cold-water species, causing an increase in animals and plants originating from the Atlantic Ocean or further south. Through the description and evaluation of the long-term evolution of this shifts, SeaWatch-B can provide science with the necessary data to inform and advise policy.

Trained volunteers have been conducting standardised surveys along various costal transects, four times a year since 2024, to provide data on beach usage, marine life, sea temperatures, pollution and early dune formation, and they will issue a report in 2026.

Noise pollution in the North Sea: Marine Environment Service and DG Shipping launch awareness campaign supported by LifeWatch VLIZ

The North Sea is one of the busiest seas in the world. All this human activity creates a lot of noise underwater, that can have harmful consequences for marine mammals and other organisms. This noise pollution originates primarily through shipping, explosive ordnance disposal, sonar, the construction of wind farms, and sand extraction and dredging.

The Marine Environment Service (FPS Public Health) and the Shipping Directorate-General (FPS Mobility), with the support of LifeWatch Belgium (VLIZ), are collaborating on a campaign to raise awareness about underwater noise pollution among the wider public and promote measures, that fortunately exist, to limit noise pollution.

This is a very important objective: for many marine species, such as marine mammals, fish, and even invertebrates, hearing is a crucial sense to survive in the dark underwater environment. Sound waves help these species perform vital functions such as orientation, communication, finding food and reproduction.

In addition, they propagate much more efficiently underwater than in the air, as they are less attenuated and move up to five times faster, posing a real threat to the marine wildlife in the Northern Sea.

The campaign is part of the OSPAR Convention collective actions to reduce noise pollution, that include the application of measures such as improved ship design, reduced vessel speed, a bubble curtain during pile driving, or the gradual startup of sonar devices or machinery used for pile driving.

VLIZ, the Flanders Marine Institute, is contributing to this plan with the help of LifeWatch Belgium and currently developing a library of long-term underwater sounds from the North Sea, set to launch in the summer of 2025. Well-described sound events will be ingested by the library and available according to the FAIR data principles.

LifeWatch Belgium: 72 shell species identified in the Big Seashell Survey event

Shells species

The eighth edition of the Big Seashell Survey, held in March, gathered more than 3,500 participants across 400 km of coastline in northern France, Belgium, and the Netherlands, breaking the previous years’ records!

Participants collected and identified nearly 150,000 shells from 72 different species, with few differences between the three countries, although the cut trough shell, the Atlantic jackknife clam, the banded wedge shell, and the common cockle made it to the top five in all three of them.

The Big Seashell Survey is one of the largest European marine citizen science projects: in Belgium it is coordinated by The Flanders Marine Institute (VLIZ), in partnership with EOS wetenschap, Natuurpunt, Provincie West-Vlaanderen, Strandwerkgroep, Kusterfgoed, and 10 coastal municipalities.

The examination of thousands of common cockle shells on the Belgian coast led to interesting findings. The cockles’ colour showed that the vast majority of these shells are in fact subfossils: hard remains from decades, or even thousands of years ago. It seems that the currently living cockle populations are, in fact, extremely rare, at least in the regions taken under exam. The blue-gray colour, moreover, seems to be associated with low-oxygen environments where the remains might have been buried, such as clay or organic matter. This was the case for 56% of the examined samples, while the ones in brighter colours might have laid in well-oxygenated environments, like gullies or open beach areas.

Join LifeWatch ERIC’s Thematic Services Working Groups

Thematic Services Working Groups

LifeWatch ERIC launches the minisites of the six Thematic Services Working Groups: hubs for knowledge and resources sharing, networking, and collaboration.

Co-developed by the LifeWatch ERIC Common Facilities in collaboration with the National Distributed Centres, they reflect the main priority areas of e-Service construction, and therefore are central to the 2022-2026 Infrastructure Strategic Working Plan.

The Thematic Services Working Groups are coordinated by the LifeWatch ERIC Service Centre and pursue three main objectives:

  • Strengthen collaboration between and within the Common Facilities and the Distributed Centres;
  • Review and update the mapping of the National scientific communities’ research needs in relation to the Thematic Services, and identify priority areas for development;
  • Promote and coordinate the participation of Distributed Centre research institutions in Horizon Europe and other European and international projects, on behalf of and in collaboration with LifeWatch ERIC, to co-design and co-construct the priority services with other key actors in the biodiversity and ecosystem research landscape.

The initiative officially took off in 2024, marked by a series of Thematic Service Workshops hosted by the National Distributed Centres, engaging local communities from the start.

Today, we are glad to present the Working Groups on the website: six dedicated entry points, each focused on a specific topic and open for participation!
Each page offers a brief overview of the scope and objectives, as well as a timeline of activities, including some future actions already planned.

The activities in each group are led by a coordinator from one of our National Distributed Centres, who will oversee the follow-up of its activities.

Moreover, the abstract submission topics for this year’s ‘BEeS’, LifeWatch ERIC’s Biodiversity & Ecosystem eScience Conference, have been selected in alignment with those of the Working Groups, given that they had been previously identified as key priority areas by the National Distributed Centres.

What are you waiting for? Find out more about the Working Groups, join forces with fellow experts and contribute to biodiversity and ecosystem research!

WoRMS reveals the list of ten remarkable new marine species from 2024

remarkable marine species

Every year, the World Register of Marine Species releases its annual list of the top ten remarkable marine species described by researchers during the previous year.

We are glad to announce that the 2024 list was revealed on 19 March, a date that coincides with World Taxonomist Appreciation Day. This date was not randomly chosen: it is worth noting that over 340 taxonomists around the world contribute their time to keeping the World Register of Marine Species up to date, and this is WoRMS’ way of acknowledging their work and celebrating taxonomists worldwide.

Selecting the top ten was no easy task, with an average of 2,000 fascinating new marine species discovered every year, and over 3,200 described in 2024 alone. The call for nominations was announced in December 2024 and sent to all WoRMS editors and major taxonomy journals.

The final decisions reflect the immense diversity of taxonomic groups in the marine environment, including crustaceans, corals, sponges, jellies, and worms.

About WoRMS: hosted by the Flanders Marine Institute (VLIZ), within LifeWatch Belgium (the National Distributed Centre of LifeWatch ERIC – more info here), the World Register of Marine Species grew out of the ERMS, the European Register of Marine Species, combined with a series of registers maintained at the Flanders Marine Institute (VLIZ).

Twaite Shad returns to the Scheldt River after 100 years

We recently shared news about the deployment of a network of fish detection devices along the Leie and the Scheldt rivers (you can find the article here). The Institute for Nature and Forest Research (INBO) has been working for years to protect fish species in the Flanders region. It is, in fact, the independent research institute of the Flemish government that underpins and evaluates biodiversity policy and management through applied scientific research.

Today we bring you a success story, one of those unexpected surprises that truly reward researchers for their dedication.

The twaite shad (also known as the “May fish” by locals), is a migratory fish species once completely disappeared from the Scheldt River due to pollution. Notably, it has made a remarkable return in the past decade.

Easily recognised by the six to ten black spots along its body and its forked tail, the twaite shad migrates upriver to spawn between late April and early May, giving it its nickname.

Its comeback has being monitored since 2014 using LifeWatch Belgium’s acoustic telemetry and data loggers to track its movement and habits. A very significant event that says something about the improving quality of water in the Scheldt river and the positive impacts of conservation efforts.

You can read more about this on the LifeWatch Belgium channel.

Fish migration monitoring in the Leie and Scheldt Rivers

Fish migration

Mapping the migration patterns of fish species is extremely important for researchers, as it allows them to offer better protection against various obstacles.

Every year in fact, millions of fish migrate to their spawning and rearing habitats, where they lay eggs and nurture their young. For some, this means swimming thousands of miles before they can reach their destination, often finding areas blocked by human-made barriers such as dams and navigation lock complexes.

When fish cannot reach their habitat, they cannot reproduce and build their population, for this reason it is important to provide effective solutions.

This is the case in the Leie and Scheldt rivers, which flow from the French border to the Netherlands. The Flemish waterway authority, De Vlaamse Waterweg, has tackled the issue by investing in the construction of fish passages to make these barriers more navigable. A study is monitoring the passage of fish through the pathways, in order to assess the impact of human barriers and the success of these mitigation measures.

Researchers from the Institute for Nature and Forest Research (INBO) have spent the last weeks deploying an extensive network of detection devices along the rivers, focusing in particular on six fish species.

World Register of Marine Species calls for Top-Ten marine species nominations

marine species

As we carry on with our daily lives working, researching, and attending events, taxonomists are working hard to discover new species every year. Now, the time has come to celebrate their discoveries by submitting nominations for the World Register of Marine Species (WoRMS) Top-Ten Marine Species of 2024!

The aim of a World Register of Marine Species is to provide a list of names and synonyms of marine organisms, so that it can serve as a guide to interpret taxonomic literature.

The content of the register is controlled by taxonomic and thematic experts: each taxonomic group is represented by an expert who has authority over the content, and is responsible for controlling the quality of the information.

This year’s Top-Ten list will be revealed on the 19th of March 2025, to mark World Taxonomist Appreciation Day, a tribute to the researchers behind these findings.

The WoRMS Top-Ten list collects last year’s most interesting new marine species, bringing them to the attention of the wider public.
The best nominations have a compelling story behind their discovery, whether it’s a species with a rare or unusual morphology, an interesting name, or societal significance.

Submissions are open until Friday, 7th of February, only for species that have been published in 2024. If you are interested in submitting your nomination, you can find additional details here: https://www.lifewatch.be/news/call-nominations-worms-top-ten-marine-species-2024.

How LifeWatch Belgium supports science at the Ghent University Museum

Ghent University Museum and WoRMS

The Ghent University Museum (GUM) and Botanical Garden represent an innovative approach to science communication in Flanders and beyond. Located in the heart of Ghent’s Botanical Garden, this institution is the first recognised university museum in Flandres. With a history spanning over 200 years and a collection of more than 400,000 items, the GUM is an example of how universities can bridge the gap between academia and society.

As a “Forum for Science, Doubt & Art,” the GUM showcases how scientists think and work, encouraging visitors – be they students, researchers, or the general public – to embrace the processes of trial, error, and imagination. Behind the scenes, however, ensuring the scientific accuracy of its exhibits is no small feat. This is where LifeWatch Belgium, through the World Register of Marine Species (WoRMS), comes into play.

The World Register of Marine Species (WoRMS), managed as part of LifeWatch Belgium’s Species Information Backbone, has been instrumental in preparing the GUM’s permanent collection for public display. Specifically, WoRMS has been used to verify the scientific and common names of species featured in the museum, ensuring that visitors engage with the most accurate and up-to-date taxonomic information available.

WoRMS provides an authoritative and detailed list of marine species names, including synonymy information. This makes it a vital tool for institutions like the GUM, to ensure that academic collections meet the highest standards of taxonomic precision.

LifeWatch Belgium provides tools and resources like WoRMS to support research, education, and public engagement initiatives. Its collaboration with institutions such as the GUM highlights the critical role of biodiversity data infrastructures in connecting science with society.
