Flamboyant and lethal: unveiling the lionfish invasion of the Mediterranean Sea

So-called ‘devil firefish’ are taking over new waters with little resistance from native species.

Research from Wageningen University and Research, the Netherlands, reveals invasive lionfish are rapidly expanding their territory in the Mediterranean sea, causing severe ecological damage.

Published in the open-access journal NeoBiota, the study shows the lionfish species Pterois miles – known as the devil firefish –  has established presence in the eastern Mediterranean, with observations now extending to colder waters previously thought to be unsuitable for the species.

Originating from the Indo-Pacific region, the lionfish species Pterois miles and Pterois volitans  are regarded as the most successful and lethal invasive fishes in marine ecosystems, with the capacity to drastically affect local fish communities and biodiversity in invaded areas.

The invasion of Pterois miles in the Mediterranean Sea began around ten years ago. Genetic studies reveal the invasive fish originated from the Red Sea and likely entered through the Suez Canal.

Lionfish are generalist predators and impact ecosystems by preying extensively on local fishes, including endemics of high conservation value. As they are unaccustomed to lionfish, native prey species usually do not flee from this new predator.

“After years studying these predators, I find it amazing how they can easily adjust to so many different environments and be successful in areas so different from where they evolve.”

“It is always impressive to see how such a flamboyant and–to us–conspicuous predator can approach its prey without being noticed”

The study’s lead author, Davide Bottacini.

The fin spines of Pterois miles are highly venomous. A sting can cause extreme pain, sickness, convulsions, minor paralysis, and breathing difficulties in humans. Immediate emergency medical attention is recommended for anyone stung by the species.

By reviewing existing scientific data, researchers identified gaps in current understanding of the lionfish’s interactions with Mediterranean ecosystems.

They suggest that, while they consider the eradication of invasive lionfish impossible, tackling questions such as the community-level impact of them in the Mediterranean, and the evolutionary and learned responses in prey, will add to the body of knowledge on the best documented invasion in marine ecosystems.

Such information provides insights vital for biodiversity conservation, with practical implications for policy makers aiming to devise efficient mitigation plans.

Citizen science initiatives for tracking and reporting lionfish sightings are encouraged to provide valuable data that supports ongoing research efforts. Such community involvement is essential for enhancing understanding of the invasion dynamics and devising effective control measures.

Deciphering cyrillics: revealing the myxomycetes of Ukraine from invisible sources

A new study compiles over 150 years of research on Ukraine’s myxomycetes – amoebae that form fascinating fungi-like fruiting bodies.

Guest blog post by Iryna Yatsiuk

Occurrences of myxomycetes in Ukraine from the present study.

Myxomycetes, or slime molds, despite their unassuming name, are fascinating organisms that play a crucial role in forest ecosystems. They live as single-cell amoebae in soil or all sorts of plant debris, where they feed on microscopic bacteria, algae, and fungi. However, when it is time to reproduce and disseminate, these tiny amoebae fuse with each other and form slimy, mobile structures – plasmodia. Plasmodia slowly but actively crawl on the substrate, and eventually transform into fungi-like fruiting bodies filled with spores. Both plasmodia and fruiting bodies are visible with the naked eye and can be easily found e.g. on decaying wood or on the forest floor.

Myxomycetes are unusual in their life cycle and very eye-catching – if only one knows where to look for them. No wonder that they have attracted the attention of naturalists for centuries. On the territory of Ukraine, observations of myxomycetes first appeared in the first half of 19th century and have been occurring sporadically in the mycological literature ever since.

However, much valuable information about the myxomycetes of Ukraine before our study was in a “grey zone”. This includes undigitized historical books and articles published in languages such as Polish, French, or German. Furthermore, there is a significant body of proceedings of local conferences, articles in local journals, and reports produced by the employees of protected areas. Yet, many of these publications existed only in print and were written in the Cyrillic alphabet, so they remained difficult to discover, to access, or to work with.

Within this study, published in Biodiversity Data Journal, we aimed to summarize all published research on myxomycetes of Ukraine, which spans over 150 years, and make the data, as well as the literature behind the data, open and easy to use. For this, we collected and mined 91 publications on this topic, spanning the years 1842 to 2023. As the result, we extracted over 5000 occurrences of myxomycetes that belong to 331 species. The produced datasets we published on GBIF, and the major part of the literature sources on the platform Zenodo.org in open access.

With this initiative, we aimed to open to the wider audience and digitally preserve some part of the biodiversity data heritage of Ukraine that is currently under threat of destruction.

This study was substantially driven by the BioDATA project, which helped a lot in developing biodiversity data management skills in our team.

NOAA Fisheries Zoologist Describes New Fish Species

Dr. Katherine Bemis of the National Systematics Laboratory recently helped describe a new species of fish, the papillated redbait.

New species alert! Dr. Katherine Bemis of NOAA Fisheries’ National Systematics Laboratory and her collaborators recently described a new fish species: Emmelichthys papillatus, or the papillated redbait. Its discovery was published in the journal ZooKeys.

The papillated redbait is a member of the family Emmelichthyidae. There are only 18 known species in this family, which are commonly called redbaits, rovers, or rubyfishes. These deepwater species can be found in warm, tropical waters and are usually bright shades of red, orange, and pink.

How did Bemis and her team make this remarkable discovery? To find out, we’ll have to first travel to a fish market in the Philippines.

A molecular mystery

As part of an interagency campaign to create a reference library of fish DNA “barcodes,” Bemis and her colleagues regularly travel abroad to collect fish specimens. Some come from seafood markets overseas where they are being sold for food. In the field, these new specimens are assigned a preliminary species identification. Then, they’re transported to the Smithsonian Institution and National Systematics Laboratory for genetic sequencing, data collection, and a secondary species confirmation.

Since getting involved with this project in 2021, Bemis and teammate Dr. Matthew Girard of the Smithsonian National Museum of Natural History have analyzed thousands of samples. None have made a bigger splash, though, than two small pink fish collected from a Philippine fish market on the island of Cebu.

While collecting data from these specimens, Girard made an exciting observation. Their genetic sequences did not match their initial species identification as golden redbaits—or any other species in the genetic library, for that matter. So which species did Girard and Bemis have on their hands?

In search of answers, Bemis and Girard examined other aspects of the specimens’ biology, including their anatomy. They discovered that these fish differed from the golden redbait in several ways, including:

  • A different number of gill rakers, structures inside the mouth that help fish to feed
  • A different number of pectoral fin rays
  • Two fleshy structures called papillae on the pectoral girdle

These differences, combined with the genetic data, provided evidence that the two specimens were not golden redbaits, but a previously undiscovered species. With only two confirmed specimens, Bemis and Girard wondered if other individuals could be identified in global natural history collections.

After some detective work, Bemis and Girard spotted a third specimen they hypothesized might also be the undescribed species. A fish with similar color also identified as a golden redbait had been collected from a fish market in the Philippines by the Kagoshima University Museum in Japan. Bemis and Girard studied the specimen and confirmed their hypothesis with genetic and anatomical data. This specimen became the third record of papillated redbait and, ultimately, the holotype for the species—the specimen upon which a new species description is based.

More to discover

Even after describing new species, there’s always more to learn. Bemis and Girard are energized that there is still much to discover about the papillated redbait and the redbait family, which is relatively poorly known. Any opportunity to add to this small body of knowledge and study redbait species in greater detail is valuable. “I’ve had researchers that work on fish taxonomy say to me, ‘I didn’t even know this family existed.’ That’s how little we know about this group,” Girard emphasizes.

Bemis also notes that because data on the papillated redbait comes from only three specimens purchased in fish markets, she still has lots of questions. For example, Bemis says that they don’t yet know if the new species occurs outside Philippine waters, or the exact habitat in which they occur. “We also don’t know anything about their reproduction or what they eat—really basic aspects of their biology remain to be studied. Now that we recognize that it is different, we only have more to study as new specimens of papillated redbait are collected,” Bemis says.

“It is always a happy and productive moment working with U.S. scientists,” says Dr. Mudjekeewis “Mudjie” Santos of the Philippine National Fisheries Research and Development Institute. Santos was instrumental in the collection of specimens, providing fisheries data on the papillated redbait, and coining a name for the new species in Tagalog, the national language of the Philippines.

One thing is for certain, though. There are more species just waiting to be discovered, and they might be right under our noses. “I think the craziest thing is that the papillated redbait is a new species that came from a market,” Girard says. “The fact that there are undescribed species being sold without us even realizing it underscores how much we still have to learn about marine biodiversity.”

Pensoft took a BiCIKL ride to Naturalis to report on a 3-year endeavour towards FAIR data

Three years ago, the BiCIKL consortium took to traverse obstacles to wider use and adoption of FAIR and linked biodiversity data.

Leiden – also known as the ‘City of Keys’ and the ‘City of Discoveries’ – was aptly chosen to host the third Empowering Biodiversity Research (EBR III) conference. The two-day conference – this time focusing on the utilisation of biodiversity data as a vehicle for biodiversity research to reach to Policy – was held in a no less fitting locality: the Naturalis Biodiversity Center

On 25th and 26th March 2024, the delegates got the chance to learn more about the latest discoveries, trends and innovations from scientists, as well as various stakeholders, including representatives of policy-making bodies, research institutions and infrastructures. The conference also ran a poster session and a Biodiversity Informatics market, where scientists, research teams, project consortia, and providers of biodiversity research-related services and tools could showcase their work and meet like-minded professionals.

BiCIKL stops at the Naturalis Biodiversity Center

The main outcome of the BiCIKL project: the Biodiversity Knowledge Hub, a one-stop knowledge portal to interlinked and machine-readable FAIR data.

The famous for its bicycle friendliness country also made a suitable stop for BiCIKL (an acronym for the Biodiversity Community Integrated Knowledge Library): a project funded under the European Commission’s Horizon 2020 programme that aimed at triggering a culture change in the way users access, (re)use, publish and share biodiversity data. To do this, the BiCIKL consortium set off on a 3-year journey to build on the existing biodiversity data infrastructures, workflows, standards and the linkages between them.

Many of the people who have been involved in the project over the last three years could be seen all around the beautiful venue. Above all, Naturalis is itself one of the partnering institutions at BiCIKL. Then, on Tuesday, on behalf of the BiCIKL consortium and the project’s coordinator: the scientific publisher and technology innovator: Pensoft, Iva Boyadzhieva presented the work done within the project one month ahead of its official conclusion at the end of April.

As she talked about the way the BiCIKL consortium took to traverse obstacles to wider use and adoption of FAIR and linked biodiversity data, she focused on BiCIKL’s main outcome: the Biodiversity Knowledge Hub (BKH).

Key results from the BiCIKL project three years into its existence presented by Pensoft’s Iva Boyadzhieva at the EBR III conference.

Intended to act as a knowledge broker for users who wish to navigate and access sources of open and FAIR biodiversity data, guidelines, tools and services, in practicality, the BKH is a one-stop portal for understanding the complex but increasingly interconnected landscape of biodiversity research infrastructures in Europe and beyond. It collates information, guidelines, recommendations and best practices in usage of FAIR and linked biodiversity data, as well as a continuously expanded catalogue of compliant relevant services and tools.

At the core of the BKH is the FAIR Data Place (FDP), where users can familiarise themselves with each of the participating biodiversity infrastructures and network organisations, and also learn about the specific services they provide. There, anyone can explore various biodiversity data tools and services by browsing by their main data type, e.g. specimens, sequences, taxon names, literature.

While the project might be coming to an end, she pointed out, the BKH is here to stay as a navigation system in a universe of interconnected biodiversity research infrastructures.

To do this, not only will the partners continue to maintain it, but it will also remain open to any research infrastructure that wishes to feature its own tools and services compliant with the linked and FAIR data requirements set by the BiCIKL consortium.

On the event’s website you can access the BiCIKL’s slides presentation as presented at the EBR III conference.

What else was on at the EBR III?

Indisputably, the ‘hot’ topics at the EBR III were the novel technologies for remote and non-invasive, yet efficient biomonitoring; the utilisation of data and other input sourced by citizen scientists; as well as leveraging different types and sources of biodiversity data, in order to better inform decision-makers, but also future-proof the scientific knowledge we have collected and generated to date.

Project’s coordinator Dr Quentin Groom presents the B-Cubed’s approach towards standardised access to biodiversity data for the use of policy-making at the EBR III conference.

Amongst the other Horizon Europe projects presented at the EBR III conference was B-Cubed (Biodiversity Building Blocks for policy). On Monday, the project’s coordinator Dr Quentin Groom (Meise Botanic Garden) familiarised the conference participants with the project, which aims to standardise access to biodiversity data, in order to empower policymakers to proactively address the impacts of biodiversity change.

MAMBO: another Horizon Europe project where Pensoft has been contributing with expertise in science communication, dissemination and exploitation, was also an active participant at the event. An acronym for Modern Approaches to the Monitoring of BiOdiversity, MAMBO had its own session on Tuesday morning, where Dr Vincent Kalkman (Naturalis Biodiversity Center), Dr France Gerard (UK Centre for Ecology & Hydrology) and Prof. Toke Høye (Aarhus University) each took to the stage to demonstrate how modern technology developed within the project is to improve biodiversity and habitat monitoring. Learn more about MAMBO and Pensoft’s involvement in this blog post.

MAMBO’s project coordinator Prof. Toke T. Høye talked about smarter technologies for biodiversity monitoring, including camera traps able to count insects at a particular site.

The EBR III conference also saw a presentation – albeit remote – from Prof. Dr. Florian Leese (Dean at the University of Duisburg-Essen, Germany, and Editor-in-Chief at the Metabarcoding and Metagenomics journal), where he talked about the promise, but also the challenges for DNA-based methods to empower biodiversity monitoring. 

Amongst the key tasks here, he pointed out, are the alignment of DNA-based methods with the Global Biodiversity Framework; central push and funding for standards and guidance; publication of data in portals that adhere to the best data practices and rules; and the mobilisation of existing resources such as the meteorological ones. 

Prof. Dr. Florian Leese talked about the promise, but also the challenges for DNA-based methods to empower biodiversity monitoring. He also referred to the 2022 Forum Paper: “Introducing guidelines for publishing DNA-derived occurrence data through biodiversity data platforms” by R. Henrik Nilsson et al.

He also made a reference to the Forum Paper “Introducing guidelines for publishing DNA-derived occurrence data through biodiversity data platforms” by R. Henrik Nilsson et al., where the international team provided a brief rationale and an overview of guidelines targeting the principles and approaches of exposing DNA-derived occurrence data in the context of broader biodiversity data. In the study, published in the Metabarcoding and Metagenomics journal in 2022, they also introduced a living version of these guidelines, which continues to encourage feedback and interaction as new techniques and best practices emerge.

Exploring ‘sufficiency’: an overlooked strategy for protecting biodiversity?

Decision makers are urged to re-evaluate their priorities.

A study from the Technical University Berlin suggests ‘sufficiency’ should be a more prominent strategy for protecting biodiversity.

Published in the open-access journal Nature Conservation, the paper analyses the intersection between biodiversity conservation and sufficiency strategies aimed at reducing consumption and resource use.

Study author Marianne Hachtmann notes that despite the established connection between excessive resource use by humans and biodiversity loss, there is limited explicit focus on how sufficiency strategies can support biodiversity preservation.

Reviewing literature from 2017 to 2021 and publications by nature conservation associations, the research identifies a notable gap in discussions linking sufficiency directly with biodiversity outcomes. Possible reasons for this may be the term’s political implications, lack of descriptiveness, and the use of other terms.

Methodology diagram
Research methodology

Furthermore, the lack of connection between sufficiency and biodiversity could be because they belong to different ‘scientific spheres’. Linking the two terms thus requires a reflective, interdisciplinary perspective.

The study proposes a detailed sufficiency typology to foster a systematic approach towards integrating the term in biodiversity conservation efforts.

“The sufficiency typology developed here allows for a systematic integration of sufficiency into biodiversity conservation and thus a joint consideration of social and nature conservation concerns.”

Marianne Hachtmann, Technical University Berlin

Policymakers, conservationists, and researchers are urged to prioritise sufficiency for the broader strategy for biodiversity conservation and sustainable living. The paper calls for further investigation into how sufficiency strategies can be crucial in conserving biodiversity and promoting sustainability.

Melting glaciers provide new ground for invasive species

A case study on the island of South Georgia.

Invasive species spread through human activities are one of the main causes of the ongoing biodiversity crisis.

Even on South Georgia, a remote island located in the very south of the Atlantic Ocean, exotic species are present. Many of which were inadvertently introduced by whalers and sealers in the 19th and early 20th century.

The invasive carabid ground beetle, Merizodus soledadinus, is present on sites that have been recently exposed by melting glaciers.

In a new study published in the open-access journal Neobiota and funded by Darwin Plus, researchers explored how living organisms colonise new ground provided by melting glaciers.

Like other cold regions of the world, South Georgia is losing its glaciers because of climate change, leaving behind large areas of newly uncovered bare ground.

Invasive annual meadow grass colonising ground only a few years after the glacier disappeared.

Researchers surveyed the foreland biodiversity of six glaciers, creating an inventory of the flora and fauna that colonise forelands at different stages of glacial retreat.

They found that, just a few years after bare ground is exposed by a glacier melting, pioneer plants arrive, progressively covering more ground with time, followed by an increasing number of species.

Native and exotic plants, as well as invertebrates, take advantage of this opportunity. Surprisingly, two temperate plant species from the Northern Hemisphere, annual meadow grass and mouse-ear chickweed, colonise sites faster than any other species.

The team suggests their results indicate invasive species will likely spread on South Georgia as fast as glaciers are retreating. Whether this has or will have negative consequences on local species needs to be investigated to help protect this unique ecosystem.

Orchard meadows: reviving Europe’s forgotten landscapes

Researchers call for political and public support to protect these areas.

A study spearheaded by researchers at the Helmholtz Centre for Environmental Research and Macquarie University has highlighted the important ecological role of traditional orchard meadows, calling for political and public support and incentives for farmers to protect these landscapes.

The paper, published in the open-access journal Nature Conservation, reviews the effects of management, habitat and landscape characteristics on the biodiversity of these areas in Central Europe.

Orchard meadow management graphic.
Schematic figure illustrating the effects of management intensification on species richness. The graph illustrates the potential effect of management intensity (from high over intermediate to abandonment/rewilding) on species richness in orchard meadows. 

Orchard meadows, characterised by the combination of cultivated grasslands and scattered fruit trees, exhibit high flora and fauna biodiversity. Despite their ecological value, these habitats have been in decline since the mid-19th century due their decreasing economic worth. They now face threats from land abandonment and intensification of agriculture.

The study emphasises the importance of moderate management intensity, connectivity to neighbouring habitats, and the preservation of structural diversity to maintain and enhance the conservation value of orchard meadows. The findings also advocate for a nuanced understanding of management impacts across taxonomic groups and points out the limitation of available studies on these habitats in Central Europe.

Currently loose in definition, the research team advocated for a clear definition of orchard meadows to create a common term in Europe, which would make their assessment and protection more straightforward. They suggest orchard meadows should be listed in the Habitats Directive of the Council of the European Union and farmers should get incentives for their maintenance. Finally, the research team calls for political and public support to prevent the loss and abandonment of these biodiverse landscapes.

“One way the public support the protection of these habitats is through consumer behaviour, specifically by purchasing local products from orchard meadows. However, it is crucial to subsidise these local products and prioritize them at local markets.

“As long as fruits from orchard meadows are treated as ‘by-products’ in the market, it will be challenging to convince people to buy local products. This change is necessary to close the economic gap between intensified fruit production and extensive orchard meadows.”

Rare bee species discovery links the French Alps to Turkey and Iraq

The new species has a narrow ecological niche, making it vulnerable to climate change and agricultural practices.

European researchers have discovered a new species of osmiine bee with an unusual geographic distribution.

Hoplitis onosmaevae is currently found exclusively in the Mercantour National Park in the French Alps and disparate mountainous regions in Turkey and Northern Iraq. The distance of more than 2000 km between these areas highlights a significant biogeographic disjunction.

Distribution map of Hoplitis onosmaevae.

Described in the open-access journal Alpine Entomology, the new bee species demonstrates unique ecological characteristics such as its distinct nesting behaviour in dead wood.

Presumed to only harvest pollen from Onosma species, it has a long proboscis, which is likely an adaptation to collect nectar from the long-tubed flowers of this genus.

The strongly disjunct distribution of Hoplitis onosmaevae has important implications for conservation. The species likely has a very narrow ecological niche, making it highly susceptible to future changes in its habitats, for example due to changes in agricultural practices or to climate change.

“The consideration of the few known populations of this species in France is very important in the conservation field,” says lead author Matthieu Aubert, freelance entomologist and member of the Observatoire des Abeilles association.

“This study highlights the incredible diversity of wild bees and that we still have a lot to learn from our environment, even in western Europe,” he continues.

The researchers emphasise the need for detailed conservation plans in the southwestern Alps to ensure the survival of Hoplitis onosmaevae, considering its highly specialised ecological niche and consequently its vulnerability to habitat changes. Their proposals for initial conservation steps can be found in the full research paper.

“Tiny, beautiful, and completely unknown animals”: Citizen scientists discover new beetles from the Borneo forest

The field trip allowed laypeople to participate in the study of biodiversity, and to discover and name a new species.

The undiscovered small beetles in the tropical rainforest are probably endless. But that did not discourage citizen scientists on expeditions to the Ulu Temburong forest in Borneo to keep adding them to scientific records, one at a time. Together with a team of researchers, they published a new species, Clavicornaltica mataikanensis in the open-access peer-reviewed Biodiversity Data Journal.

The minute, two-mm-long leaf beetle that lives on the forest floor is the latest discovery of Taxon Expeditions, which organises scientific field trips for teams consisting of both scientists and lay people. Unlike other science/adventure trips, Taxon Expeditions organises real scientific expeditions for lay people, guiding them in the discovery of new species of animals, by focusing on the thousands of ‘little things that run the world’.

Clavicornaltica mataikanensis, named for the stream Mata Ikan (“fish eye”) that runs in the valley where it was found, is one of a plethora of tiny beetle species that live in the leaf litter of tropical forests—and most of them have not yet been scientifically described and named. At 2 mm long, the flea beetle is actually one of the largest among its relatives – which might explain why so little is known about their ecology and diversity.

The field trip, in which local students and researchers also took part, gave untrained lay people the opportunity to participate in the study of this hidden world of biodiversity and in the process of naming and publishing new species. Participant Lehman Ellis, from the US, says it was “exciting and beautiful” to be part of the discovery.

Providing solutions to restoring the natural water retention function of landscapes: Pensoft joins the SpongeBoost project

At SpongeBoost, Pensoft is to take charge of the project’s identity, while building a strong network, and providing comprehensive knowledge and well-packaged information.

In recent years, Europe’s landscapes have become the victims of extreme events – ranging from floods to droughts – that have caused considerable damage to nature as well as human society. 

With the aim to tackle such severe circumstances, the newly-started Horizon Europe-funded project SpongeBoost will be working towards protecting and promoting natural sponge landscapes

Within SpongeBoost, the functional capacity of sponge landscapes is to be enhanced through building upon existing solutions and their large-scale implementation, but also through innovative approaches.

Pensoft is among the partnering institutions within SpongeBoost and serves as the leader of Work Package #5: “Communication, dissemination, exploitation, showcasing best practices and networking”. WP5 will aim to contribute to the project’s mission by building the overall project identity, building a strong network, and providing comprehensive knowledge and well-packaged information to targeted stakeholders.

The project 

Funded by the European Union’s Horizon Europe research and innovation programme with a budget of EUR ~3 million, the project is coordinated by the Helmholtz Centre for Environmental Research (UFZ) and will be developed with the active participation of 10 partnering institutions from seven countries across Europe. Having been officially launched in January 2024, SpongeBoost is to wrap up in December 2027. 

The project is part of the EU mission “Adaptation to Climate Change”, whose task is to support EU regions, cities and local authorities in their efforts to build resilience against the impacts of climate change.

The protection and revitalisation of wetlands, particularly through peatland rewetting and river floodplain restoration, plays a central role in this,

says project manager Mathias Scholz from the UFZ. 

SpongeBoost held its official kick-off meeting in late February (2024) in Leipzig, Germany.

To officially kickstart the project, the first consortium meeting took place on 21-23 February in Leipzig, Germany. The kick-off meeting saw all 10 partnering institutions meet in person to officially lay the foundation of a promising collaboration that will flourish over the next four years.

The joint mission before the newly formed consortium is to enhance the natural sponge function of wetlands and soils in Europe, aligning with EU policies for climate adaptation, disaster risk reduction and biodiversity. To achieve that, the project plans to employ both bottom-up and top-down approaches, which will foster networking and synergy at the regional and EU level.

SpongeBoost will focus on five main objectives over the next four years:

  1. Conduct a comprehensive literature review to create a standard reference catalogue for securing and enhancing sponge functions in adaptation to climate change. This catalogue will integrate social, economic, technical, and ecological effects and serve as a widely used resource across Europe and beyond.
  1. Build a knowledge base on existing approaches for enhancing sponge functions, and highlight the reasons for success or failure. The goal is to enable regions and communities to replicate effective transformative solutions. Meanwhile, the consortium is to facilitate networking initiatives with other projects and identify suitable pilot sites for monitoring long-term success using the results of previous projects.
  1. Work on the implementation, tests, refinement, and adjustment of best practices and innovative solutions through EU-wide case studies. The goal is to enhance climate resilience to extreme events and enable upscaling from local to EU levels.
  1. Develop a roadmap with practical tools to empower stakeholders, drive transformative change, and integrate sponge solutions into regional, national and European climate adaptation processes to achieve EU Green Deal targets.
  1. Connect communities and compile online resources for climate change adaptation. The goal is to facilitate access and combine a library of tools for restoration and share research findings on soil, water, and groundwater interconnection for replication across Europe.

In addition to leading the “Communication, dissemination, exploitation, showcasing best practices and networking” work package at SpongeBoost, Pensoft is to also assist the Environmental Action Germany (DUH) in the implementation of different innovative communications methods and ideas meant to support the project’s goals.

As part of the creative communication strategy, DUH will take the lead in the development of a “SpongeBooster superhero” character. By creating such a character that will be also featured in comics, the team will translate complex concepts into clear visuals and engaging narratives, thereby shaping the project’s visual identity and letting non-experts join the discourse. The Sponge Booster is to serve as an innovative method to disseminate project knowledge and address barriers with humour while fostering dialogue and avoiding potential conflicts. 

International Consortium 

The SpongeBoost project brings together a team of 10 partners from seven European countries, spanning research, policy, and management fields. The consortium members, who individually represent various restoration projects, will join forces and expertise to promote collaboration, knowledge exchange and synergies across European regions, to ultimately instil a lasting positive impact on sponge restoration for climate change adaptation.
