Bulgaria officially joins the Global Biodiversity Information Facility (GBIF). This major event for Bulgarian science was initiated by a memorandum signed by the Minister of Environment and Water: Manol Genov.
GBIF is an international network and data infrastructure funded by governments around the world that provides international open access to a modern and comprehensive database of all species of living organisms on the planet.
Joining GBIF is an important step for initiatives such as the Bulgarian Barcode of Life (BgBOL), as it will facilitate the integration of genetic data on species diversity into the global scientific community and support the creation of a more accurate and accessible bioinformatic database. This will increase the scientific visibility and relevance of Bulgarian efforts in molecular taxonomy and conservation.
“First of all, I’d like to congratulate all fellow scientists working in the domain of biology and ecology in Bulgaria with this wonderful achievement,” says Prof. Dr. Lyubomir Penev, founder and CEO of the scientific publisher and technology provider Pensoft, as well as a key participant in the talks and preparations for Bulgaria’s joining GBIF. He is also Chair of BgBOL.
“Becoming a full member of GBIF has been a long-anticipated milestone we have discussed and worked on for several years. Coming not long after we initiated the Bulgarian Barcode of Life, the Bulgarian membership in GBIF gives us yet another uncontested evidence that the nation is on the right path to preserving our uniquely rich fauna and flora,” he adds.
Pensoft is looking forward to sharing our know-how with Bulgarian institutions and scientists in order to streamline the visibility and overall efficiency of biodiversity data collected from Bulgaria.

“As close partners of GBIF for over 15 years now, Pensoft is looking forward to sharing our know-how with Bulgarian institutions and scientists, so that they can fully utilise the GBIF infrastructure and tools, in order to streamline the visibility and overall efficiency of biodiversity data collected from Bulgaria.”
GBIF is managed by a Secretariat based in Copenhagen and brings together countries and organisations that collaborate through national and institutional coordinators (also called participant nodes). The mechanism provides common standards, good practices and open access tools for institutions around the world to share information on the location and recording of species and specimens. According to GBIF, a total of 107 countries and organisations currently participate in the network, a significant number of which are European.

By joining GBIF, biodiversity data generated in Bulgaria can be streamlined through the network’s infrastructure so that the country does not need to build and maintain its own separate infrastructure, which also saves significant financial resources.
As a full voting member, Bulgaria will ensure that biodiversity data in the country will be shared and accessible through the platform, and will contribute to global knowledge on biodiversity, respectively to the solutions that will promote its conservation and sustainable use.

Improvements in data management by Bulgaria will also contribute to better reporting and fulfilment of obligations to the Convention on Biological Diversity (CBD) as well as to the Intergovernmental Platform on Biodiversity and Ecosystem Services (IPBES). As a member of GBIF, Bulgaria will be able to apply for funding for flagship activities in Bulgarian institutions and neighbouring Balkan countries. This will enable the country to expand its leadership role in the Balkans in biodiversity research and data accumulation.
The partnership between GBIF and Pensoft dates back to 2009 when the global network and the publisher signed their first Memorandum of Understanding intended to solidify their cooperation as leaders in the technological advancement relevant to biodiversity knowledge. Over the next few years, Pensoft integrated its whole biodiversity journal portfolio with the GBIF infrastructure to enable multiple automated workflows, including export of all species occurrence data published in scientific articles straight to the GBIF platform. Most recently, over 20 biodiversity journals powered by Pensoft’s scholarly publishing platform ARPHA launched their own hosted portals on GBIF to make it easier to access and use biodiversity data associated with published research, aligning with principles of Findable, Accessible, Interoperable, and Reusable (FAIR) data.
Content from more than 30 biodiversity journals published on the ARPHA Platform will now be archived in the Biodiversity Heritage Library (BHL), the world’s largest open-access digital library for biodiversity literature and archives.
A global consortium of natural history, botanical, research, and national libraries, BHL digitises and freely shares essential biodiversity materials. A critical resource for researchers, it provides vital access to material that might otherwise be difficult to obtain.
Under the agreement, over 16,000 articles published on Pensoft’s self-developed ARPHA Platform are now available on BHL. Both legacy content and new articles are made available on the platform, complete with full-text PDFs and all relevant metadata.
Thanks to this integration, content in our journals will become even more accessible and readily discoverable, helping researchers find the biodiversity information they need.
Prof. Lyubomir Penev
More content published on ARPHA will gradually be added to the BHL archive.
The publications will be included in the Library’s full-text search, allowing researchers to easily locate relevant biodiversity literature. Crucially, the scientific names within the articles will be indexed using the Global Names Architecture, enabling seamless discovery of information about specific taxa across the BHL collection.
“Pensoft is pleased to collaborate with BHL in our joint mission to support global biodiversity research through free access to knowledge. Thanks to this integration, content in our journals will become even more accessible and readily discoverable, helping researchers find the biodiversity information they need,” said Prof. Lyubomir Penev, CEO and founder of Pensoft and ARPHA.
The news comes soon after BHL announced it is about to face a major shift in its operation. From 2026, the Smithsonian Institution – one of BHL’s 10 founding members – will cease to host the administrative and technical components of BHL. As the consortium explores a range of options, the BHL team is confident that “the transition opens the door to a reimagined and more sustainable future for BHL.”
The initiative aims to make it easier to access and use biodiversity data associated with published research, aligning with principles of Findable, Accessible, Interoperable, and Reusable (FAIR) data.
The data portals offer seamless integration of published articles and associated data elements with GBIF-mediated records. Now, researchers, educators, and conservation practitioners can discover and use the extensive species occurrence and other data associated with the papers published in each journal.

The collaboration between Pensoft and GBIF was recently piloted with the Biodiversity Data Journal (BDJ). Today, the BDJ hosted portal provides seamless access and exploration for nearly 300,000 occurrences of biological organisms from all over the world that have been extracted from the journal’s all-time publications. In addition, the portal provides direct access to more than 800 datasets published alongside papers in BDJ, as well as to almost 1,000 citations of the journal articles associated with those publications.
“The release of the BDJ portal and subsequent ones planned for other Pensoft journals should inspire other publishers to follow suit in advancing a more interconnected, open and accessible ecosystem for biodiversity research,” said Dr. Vince Smith, Editor-in-Chief of BDJ and head of digital, data and informatics at the Natural History Museum, London.

“The programme will provide a scalable solution for more than thirty of the journals we publish thanks to our partnership with Plazi, and will foster greater connectivity between scientific research and the evidence that supports it,” said Prof. Lyubomir Penev, founder and chief executive officer of Pensoft.
On the new portals, users can search data, refining their queries based on various criteria such as taxonomic classification, and conservation status. They also have access to statistical information about the hosted data.
Together, the hosted portals provide data on almost 325,000 occurrence records, as well as over 1,000 datasets published across the journals.
Guest blog post by Veronica Nanni, Jagoba Malumbres-Olarte, and Stefano Mammola
In an era where information is more accessible than ever, one might assume that communicating science has never been easier. However, science communicators often find themselves in a constant battle against public skepticism and media sensationalism. Scientific research is, by nature, intricate and nuanced, making it inherently challenging to communicate effectively. Academic papers are often laden with equations, technical jargon, and acronyms that, while ensuring precision and accuracy, may alienate even the most intrepid readers. The challenge, then, lies in translating complex findings into digestible and engaging narratives without oversimplifying or distorting the truth. Striking this balance is crucial, as misrepresentation can lead to misunderstanding, erode public trust, or even fuel misinformation.
As scientists working with subterranean biodiversity, we face an additional layer of challenges in science communication. Unlike more familiar ecosystems, such as forests or oceans, caves and other subterranean environments are foreign and unseen to most audiences. These hidden worlds are often perceived as mysterious, inhospitable, or even irrelevant to everyday life. This lack of direct experience or knowledge creates a significant barrier to interest and engagement. For instance, the delicate balance of subterranean ecosystems and their hidden interconnection with surface ecosystems is not only difficult to visualize but also challenging to relate to broader environmental issues that resonate with the public, such as climate change or biodiversity loss.

Furthermore, subterranean organisms, such as blind fish, pale invertebrates, and microbial communities, often lack the visual appeal of iconic surface species (e.g., lions, dolphins, polar bears), making it difficult to generate interest or concern. Such scarce interest often means that subterranean ecosystems are scarcely represented in global biodiversity agendas, leaving most of them unprotected or poorly regulated.
This communication challenge and policy gap became even more apparent at the start of the Biodiversa+ project DarCo, a transnational project involving 13 research institutes across Europe. The project aims to advance knowledge about subterranean biodiversity in Europe and advance its conservation. DarCo’s overarching goal is to develop a concrete plan to incorporate subterranean ecosystems into the European Union (EU) Biodiversity Strategy for 2030.
For the successful implementation of the project, there is a need to engage with diverse audiences, from the general public to stakeholders who rely on subterranean resources in various ways—e.g., speleological groups, water managers, national park authorities, and even politicians involved in EU-level legislation on nature conservation. This is where the challenge of communicating the importance of subterranean biodiversity to the health of ecological systems and the well-being of society became quite apparent. We realized that tapping into non-scientific forms of communication might offer a promising way forward.

We began collaborating with various artists and scientific illustrators to aid in our communication efforts. Whether illustrating cave life and its conservation for children (Figure 1) or involving illustrators to create compelling visuals for our scientific publications (Figure 2), the science-art collaboration proved particularly effective. We even invited a scientific illustrator, Dr. Jagoba Malumbres-Olarte, to the 26th International Conference on Subterranean Biology (Cagliari, Italy, 9–14 September 2024), where the DarCo team organized a workshop on subterranean conservation open to both scientists and stakeholders. Jagoba’s role was to create an artistic representation of the workshop flow (Figure 3) and illustrate key aspects of selected scientific talks.

Stemming from these fruitful collaborations, we decided to write a scientific paper on the role art can play in the conservation of subterranean ecosystems, highlighting the benefits for subterranean scientists engaging with artists and vice versa. Although there is no quantitative proof yet that art directly promotes subterranean conservation, our experience as scientists who frequently collaborate with artists—and artists who often collaborate with scientists—suggests that bridging these worlds can have profound, lasting impacts on scientific communication and conservation efforts. By engaging with artists, subterranean scientists can create more impactful visuals for research papers and presentations, enhance public engagement through powerful storytelling, and spark fresh insights that may drive new research directions.
To maximize these benefits, scientists should foster collaborations by inviting artists to conferences and workshops, involving them in cave expeditions, and even dedicating small portions of research budgets to artistic initiatives. On the other hand, artists can undertake projects focused on conservation and related scientific fields, using their own platforms and tapping into funding sources beyond traditional scientific grants.

Art has long been a bridge between knowledge and emotion, making complex ideas accessible through storytelling, visuals, and performance. Scientific illustrations, data visualizations, and interactive exhibits can transform abstract information into tangible experiences. Moreover, films, theater, and literature can create emotional connections with audiences, helping them grasp the real-world implications of scientific discoveries.
By integrating art with science communication, we can reach people who might otherwise feel disconnected from scientific discourse. Art and science are not opposing forces but complementary ones, enriching each other in profound ways. As we face global challenges such as climate change, biodiversity loss, and public health crises, integrating artistic expression with scientific inquiry can foster deeper understanding, empathy, and action, spreading knowledge and awareness of these threats in society.

Yet another hectic year has passed for our team at Pensoft, so it feels right to look back at the highlights from the last 12 months, as we buckle up for the leaps and strides in 2025.
In the past, we have used the occasion to take you back to the best moments of our most popular journals (see this list of 2023 highlights from ZooKeys, MycoKeys, PhytoKeys and more!); share milestones related to our ARPHA publishing platform (see the new journals, integrations and features from 2023); or let you reminisce about the coolest research published across our journals during the year(check out our Top 10 new species from 2021).
In 2022, when we celebrated our 30th anniversary on the academic scene, we extended our festive spirit throughout the year as we dived deep into those fantastic three decades. We put up Pensoft’s timeline and finished the year with a New Species Showdown tournament, where our followers on (what was back then) Twitter voted twice a week for their favourite species EVER described on the pages of our taxonomic journals.
Spoiler alert: we will be releasing our 2024 Top 10 New Species on Monday, 23 December, so you’d better go to the right of this screen and subscribe to our blog!
As we realised we might’ve been a bit biased towards our publishing activities over the years, this time, hereby, we chose to present you a retrospection that captures our best 2024 moments from across the departments, and shed light on how the publishing, technology and project communication endeavours fit together to make Pensoft what it is.
In truth, we take pride in being an exponentially growing family of multiple departments that currently comprises over 60 full-time employees and about a dozen freelancers working from all corners of the world, including Australia, Canada, Belgium and the United Kingdom. Together, we are all determined to make sure we continuously improve our service to all who have trusted us: authors, reviewers, editors, client journals, learned societies, research institutions, project consortia and other external collaborators.
After all, great deeds are only possible when you team up with great like-minded people!
In 2024, at Pensoft, we were hugely pleased to see a significant growth in the published output at almost all our journals, including record-breaking numbers in both submissions and publications at flagship titles of ours, including the Biodiversity Data Journal, PhytoKeys and MycoKeys.
Later in 2024, our colleagues, who work together with our clients to ensure their journals comply with the requirements of the top scholarly databases before they apply for indexation, informed us that another two journals in our portfolio have had their applications to Clarivate’s Web of Science successfully accepted. These are the newest journal of the International Association of Vegetation Science: Vegetation and Classification, and Metabarcoding and Metagenomics: a journal we launched in 2017 in collaboration with a team of brilliant scientists working together at the time within the DNAquaNet COST Action.
In 2024, we also joined the celebrations of our long-time partners at the Museum für Naturkunde Berlin, whose three journals: Zoosystematics and Evolution, Deutsche Entomologische Zeitschrift and Fossil Record are all part of our journal portfolio. This year marked the 10th Open Access anniversary of the three journals.
In the meantime, we also registered a record in new titles either joining the Pensoft portfolio or opting for ARPHA Platform’s white-label publishing solution, where journal owners retain exclusivity for the publication of their titles, yet use ARPHA’s end-to-end technology and as many human-provided services as necessary.

Amongst our new partners are the International Mycological Association who moved their official journal IMA Fungus to ARPHA Platform. As part of Pensoft’s scholarly portfolio, the renowned journal joins another well-known academic title in the field of mycology: MycoKeys, which was launched by Pensoft in 2011. The big announcement was aptly made public at this year’s 12th International Mycological Congress where visitors of the Pensoft stand could often spot newly elected IMA President and IMA Fungus Chief editor: Marc Stadler chatting with our founder and CEO Lyubomir Penev by the Pensoft/MycoKeys booth.
On our end, we did not stop supporting enthusiastic and proactive scientists in their attempt to bridge gaps in scientific knowledge. In January, we launched the Estuarine Management and Technologies journal together with Dr. Soufiane Haddout of the Ibn Tofail University, Morocco.
Later on, Dr. Franco Andreone (Museo Regionale di Scienze Naturali, Italy) sought us with the idea to launch a journal addressing the role of natural history museums and herbaria collections in scientific progress. This collaboration resulted in the Natural History Collections and Museomics journal, officially announced at the joint TDWG-SPNHC conference in Okinawa, Japan in August.
Around this time, we finalised our similarly exciting journal project in partnership with Prof. Dr. Volker Grimm (UFZ, Germany), Prof. Dr. Karin Frank (UFZ, Germany), Prof. Dr. Mark E. Hauber (City University of New York) and Prof. Dr. Florian Jeltsch (University of Potsdam, Germany). The outcome of this collaboration is called Individual-based Ecology: a journal that aims to promote an individual-based perspective in ecology, as it closes the knowledge gap between individual-level responses and broader ecological patterns.
The three newly-launched journals are all published under the Diamond Open Access model, where neither access, nor publication is subject to charges.
As you can see, we have a lot to be proud of in terms of our journals. This is also why in 2024 our team took a record number of trips to attend major scientific events, where we got the chance to meet face-to-face with long-time editors, authors, reviewers and readers of our journals. Even more exciting was meeting the new faces of scientific research and learning about their own take on scholarship and academic journals.
Pensoft’s CEO and founder Prof. Dr. Lyubomir Penev welcomed editors at PhytoKeys to the Pensoft-PhytoKeys-branded booth at the XX International Botanical Congress in July 2024 (Spain).
We cannot possibly comment on Pensoft’s tech progress in 2024 without mentioning the EU-funded project BiCIKL (acronym for Biodiversity Community Integrated Knowledge Library) that we coordinated for three years ending up last April.
This 36-month endeavour saw 14 member institutions and 15 research infrastructures representing diverse actors from the biodiversity data realm come together to improve bi-directional links between different platforms, standards, formats and scientific fields.
Following these three years of collaborative work, we reported a great many notable research outputs from our consortium (find about them in the open-science project collection in the Research Ideas and Outcomes journal, titled “Towards interlinked FAIR biodiversity knowledge: The BiCIKL perspective”) that culminated in the Biodiversity Knowledge Hub: a one-stop portal that allows users to access FAIR and interlinked biodiversity data and services in a few clicks; and also a set of policy recommendations addressing key policy makers, research institutions and funders who deal with various types of data about the world’s biodiversity, and are thereby responsible to ensuring there findability, accessibility, interoperability and reusability (FAIR-ness).
Apart from coordinating BiCIKL, we also worked side-by-side with our partners to develop, refine and test each other’s tools and services, in order to make sure that they communicate efficiently with each other, thereby aligning with the principles of FAIR data and the needs of the scientific community in the long run.
During those three years we made a lot of refinements to our OpenBiodiv: a biodiversity database containing knowledge extracted from scientific literature, built as an Open Biodiversity Knowledge Management System, and our ARPHA Writing Tool. The latter is an XML-based online authoring environment using a large set of pre-formatted templates, where manuscripts are collaboratively written, edited and submitted to participating journals published on ARPHA Platform. What makes the tool particularly special is its multiple features that streamline and FAIRify data publishing as part of a scientific publication, especially in the field of biodiversity knowledge. In fact, we made enough improvements to the ARPHA Writing Tool that we will be soon officially releasing its 2.0 version!
OpenBiodiv – The Open Biodiversity Knowledge Management System
ARPHA Writing Tool 2.0
Amongst our collaborative projects are the Nanopublications for Biodiversity workflow that we co-developed with KnowledgePixels to allow researchers to ‘fragment’ their most important scientific findings into machine-actionable and machine-interpretable statements. Being the smallest units of publishable information, these ‘pixels of knowledge’ present an assertion about anything that can be uniquely identified and attributed to its author and serve to communicate a single statement, its original source (provenance) and citation record (publication info).
Nanopublications for Biodiversity
In partnership with the Swiss-based Text Mining group of Patrick Ruch at SIB and the text- and data-mining association Plazi, we brought the SIB Literature Services (SIBiLS) database one step closer to solidifying its “Biodiversity PMC” portal and working title.
Understandably, we spent a lot of effort, time and enthusiasm in raising awareness about our most recent innovations, in addition to our long-standing workflows, formats and tools developed with the aim to facilitate open and efficient access to scientific data; and their integration into published scholarly work, as well as receiving well-deserved recognition for their collection.
We just can’t stress it enough how important and beneficial it is for everyone to have high-quality FAIR data, ideally made available within a formal scientific publication!

Pensoft as a science communicator
At our Project team, which is undoubtedly the fastest developing department at Pensoft, science communicators are working closely with technology and publishing teams to help consortia bring their scientific results closer to policy actors, decision-makers and the society at large.
Ultimately, bridging the notorious chasm between researchers and global politics boils down to mutual understanding and dialogue.
Pensoft’s communication team attended COP16 (November 2024, Colombia) along with partners at the consortia of CO-OP4CBD, BioAgora and RESPIN: three Horizon Europe projects, whose communication and dissemination is led by Pensoft.
Throughout 2024, the team, comprising 20 science communicators and project managers, has been working as part of 27 EU-funded project consortia, including nine that have only started this year (check out all partnering projects on the Pensoft website, ordered from most recently started to oldest). Apart from communicating key outcomes and activities during the duration of the projects, at many of the projects, our team has also been actively involved in their grant proposal drafting, coordination, administration, platform development, graphic and web design and others (see all project services offered by Pensoft to consortia).
📸As leaders of the “Stakeholder engagement, comms & dissemination” WP at @BCubedProject, we joined the annual meeting to report on project branding, #scicomm & #DataManagement.
Naturally, we had a seat on the front row during many milestones achieved by our partners at all those 27 ongoing projects, and communicated to the public by our communicators.
Amongst those are the release of the InsectsCount web application developed within the Horizon 2020 project SHOWCASE. Through innovative gamification elements, the app encourages users to share valuable data about flower-visiting insects, which in turn help researchers gain new knowledge about the relationship between observed species and the region’s land use and management practices (learn more about InsectsCount on the SHOWCASE prroject website).
Another fantastic project output was the long-awaited dataset of maps of annual forest disturbances across 38 European countries derived from the Landsat satellite data archive published by the Horizon Europe project ForestPaths in April (find more about the European Forest Disturbance Atlas on the ForestPaths project website).
In a major company highlight, last month, our project team participated in COP29 in Baku, Azerbaijan with a side event dedicated to the role of open science and science communication in climate- and biodiversity-friendly policy.
Pensoft’s participation at COP29 – as well as our perspective on FAIR data and open science – were recently covered in an interview by Exposed by CMD (a US-based news media accredited to cover the event) with our science communicator Alexandra Korcheva and project manager Boris Barov.
You see, A LOT of great things worth celebrating happened during the year for us at Pensoft: all thanks to ceaselessly flourishing collaboration based on transparency, trust and integrity. Huge ‘THANK YOU!’ goes to everyone who has joined us in our endeavours!
Here’s to many more shared achievements coming up in 2025!

Beneath the arid pre-Saharan zone of Morocco lies Aziza Cave, also known as Kef Aziza or Tazouguert Cave. The vast subterranean system stretches over 3.5 kilometers of surveyed galleries, making it Morocco’s fifth-largest cave system and one of the top ten most extensive caves in North Africa.
A view of the Sahara desert and Aziza cave’s entrance.
Beyond its sheer size and geological significance, Aziza Cave harbors a rich and diverse array of subterranean life that is only now beginning to be revealed widely. In a recent study in the journal Subterranean Biology, researchers cataloged the subterranean fauna of Aziza Cave and provided a detailed checklist of 26 different taxa potentially representing cave-restricted species. Among these are 22 troglobitic species, organisms that have adapted to life entirely within the cave environment, and four stygobitic species, which have specially evolved to live in the cave’s groundwater.
Four of the authors of the paper.
The discovery of such a variety of species highlights the cave as a critical biodiversity hotspot, not only in Morocco but for the African continent as a whole. One alarming aspect of this discovery is the large number of species that still need to be thoroughly studied or described.
Dysdera caeca, a cave spider
Only about 34.6% of the species in Aziza Cave have been formally identified and described by scientists. Further research could lead to the identification and description of many new species. The fauna found in Aziza Cave includes a wide variety of life forms, with the richest groups being beetles (Coleoptera), spiders (Araneae), springtails (Entomobryomorpha), and woodlice (Isopoda). Some have evolved remarkable adaptations to their lightless, nutrient-scarce environment, such as reduced pigmentation, elongated appendages, and heightened sensory capabilities that help them navigate and survive in this extreme habitat.
Long-tailed bat Rhinopoma hardwickei.
Despite these discoveries, much of Aziza Cave remains unexplored. Large portions of this karstic system have yet to be surveyed, and researchers believe that the biodiversity uncovered so far is just the beginning. The cave’s unexplored depths likely hold many more secrets, including potentially new species that have yet to be seen by human eyes. This prospect has sparked great interest among speleologists and conservationists, who see Aziza Cave as an important research site for studying subterranean ecosystems.
Magnezia gardei, a cave isopod.
The biodiversity of Aziza Cave is something to celebrate, but it also sheds light on the significant conservation challenges that subterranean habitats in Morocco and across North Africa are facing. Caves are delicate ecosystems that are highly sensitive to changes in their environment. Human activities such as pollution, mining, deforestation, and unsustainable tourism pose severe threats to these ecosystems and the species that depend on them. Once these habitats are damaged or destroyed, it is often impossible to restore them, and the species that inhabit them may face extinction.
Graffiti on the cave walls.
Human-induced impacts have already begun to take their toll in Aziza Cave. Visitors can disrupt the delicate balance of the cave’s ecosystem, change water quality, or introduce pollutants and alien species. These pressures underscore the urgent need for conservation measures to protect this unique environment and its inhabitants. By highlighting the importance of Aziza Cave and similar habitats, the researchers hope to encourage further exploration and study of Africa’s subterranean ecosystems and develop effective conservation strategies to protect them. By protecting these fragile ecosystems and supporting scientific exploration, we can ensure that the incredible biodiversity of Aziza Cave and other subterranean habitats continues to thrive.

Guest blog post by Petra Lukeneder and Adrienne Jochum
During the past years, interest in the processing and preservation of historical, scientific collections has increased significantly. Fascinating and obscure treasures are stored along with their individual stories while splendid and exciting specimens eke out an existence in boxes and cellars. The scientific curation of the Dominik Bilimek (1813-1884) Collection at BOKU University (Vienna, Austria) is one such example. Stored in the attic for many decades, later stashed in the basement, surviving two floods, a plethora of untold narratives unfolded as the specimens were unpacked. For example, the story of the young, aspiring, Slovenian collector and researcher, Heinrich Hauffen (1836-1866), with his special interests in speleology and the fauna inhabiting the subterranean realm come to light.
The only known photograph of collector and naturalist Heinrich Hauffen (1836-1866) (Digital Library of Slovenia; reference number 5S74D58Z).
At first, it was just a label type in the collection that differed from the others. It was a multidisciplinary process to assign it to Hauffen. At that time, only few scientists were concerned with the genus Carychium, including Georg von Frauenfeld (1807-1873), Heinrich Freyer (1802-1866), and Meinrad Thaurer von Gallenstein (1811-1872), all of whom were names that were closely linked to Bilimek and his collection. Fortunately, Hauffen’s handwriting could be identified by using original manuscripts from the Archive of the National Museum of Slovenia.
In our work published in Subterranean Biology, we present our results on the rediscovery of historical material of Heinrich Hauffen, which turned out to be original material, that he used to describe the cave snail taxa Carychium reticulatum and Carychium reticulatum bidentatum. Today, the eastern Alpine and the Dinaric subterranean members of the genus Carychium are assigned to their own genus, Zospeum, based on their troglobiontic characteristics such as lack of eyes, colourless bodies, genetic data, and their totally different shell morphology.

This interdisciplinary work not only includes historical aspects, but also a collaboration with the Natural History Museum Vienna and the Department of Evolutionary Biology (University of Vienna) in conjunction with the taxonomic expertise from the Natural History Museum Bern (Bern, Switzerland), the Senckenberg Research Institute and Natural History Museum (Frankfurt am Main, Germany) and from the Zoologische Staatssammlung München (Münich, Germany). By using light microscopy, X-ray Micro-CT data and SEM in sync with Hauffen’s original figures and handwritten documents, the morphological analysis of C. reticulatum illustrates the degree of phenotypic variation on the shells of individuals from two different cave populations of the species Zospeum spelaeum. The species Carychium bidentatum is considered a junior synonym of Zospeum costatum.

The genus Zospeum constitutes a radiation of minute, glassy troglobitic snails (Ellobioidea) endemic to the Eastern Alps and the Dinaric Alps, extending as far west as Lake Garda in Italy and as far south as Montenegro. So far, 38 species of Zospeum have been described. Morphologically, the most informative diagnostic characters are apertural form and the degree of coiling and the shape of the columella (inner spindle) as well as the presence and configuration of the lamella in relation to it. In the Pre-Micro-CT era, one had to poke windows into the shells to view these signatory structures. Valuable material could become damaged, and many taxonomists shied from risky mishaps to assess the tiny shells (< 1.5 mm). This present work demonstrates the efficacy of fine-resolution imagery to assess valuable historic material.

Hauffen died at the age of 30 as part of the Austrian volunteer corps in Mexico – with the prospect of a permanent position at the Mexican National Museum. According to current knowledge, this is the reason why the Hauffen collection was passed on to Bilimek, who returned to Europe in 1867. There are still abundant specimens, often from localities that cannot longer be sampled nowadays, from Hauffen within the Bilimek collection. In the future, this part can hopefully be separated and scientifically processed as well.

The International Congress of Entomology 2024 (ICE2024), which took place on August 25-30 2024 in Kyoto, Japan, was arguably the biggest entomology event of the year. For the Pensoft team, it was an excellent chance to catch up with our authors and editors and discuss new partnerships.
At the Kyoto International Conference Center, entomologists visited lectures, symposia, and poster presentations, but they also enjoyed insect-themed haikus, origami, and artworks, and got to sample some edible insects.

Scientific illustrator Denitsa Peneva’s beautiful works adorned Pensoft’s stand; Mostafa Ghafouri Moghaddam, subject editor at ZooKeys and Biodiversity Data Journal and author at a number of Pensoft-published journals even got to take one of her prints home after winning a raffle that Pensoft organised. He won a beautiful illustration of Bombus fragrans on Trifolium pratense.
Pensoft’s founder and CEO and one of the founding editors of the company’s flagship journal ZooKeys, Prof. Lyubomir Penev, was there representing the company and meeting with fellow entomologists.

They also got the chance to learn about the ARPHA Platform, a next-generation publishing solution that offers a streamlined and efficient workflow for authors, reviewers, and editors.
At ICE2024, Pensoft also presented its newest open-access jorunal, Natural History Collections and Museomics. A peer-reviewed journal for research, discussion and innovation of natural history collections, NHCM will publish under a diamond open access model, allowing free access to published content without any fees for authors or readers.
In addition to its publishing endeavors, Pensoft also presented some of the EU-funded pollinator projects that it takes part in such as Safeguard, PollinERA, and WildPosh.
ICE2024 was a chance to advance entomological science and foster collaboration within the global scientific community. For those who missed the chance to connect with Pensoft in Kyoto, the company’s journals and platforms remain accessible online, offering opportunities to read and produce groundbreaking research in insect diversity and ecology.
The indexing is one of the major outcomes from the partnerships within the Horizon 2020-funded project Biodiversity Community Integrated Knowledge Library (BiCIKL)
In a joint effort between the Swiss-based Text Mining group of Patrick Ruch at SIB (developing SIBiLS), the text- and data-mining association Plazi and scientific publisher Pensoft, the long-time collaborators have started feeding full-text content of over 500,000 taxonomic treatments extracted by Plazi and tens of thousands full-text articles from 40 well-renowned biodiversity journals published by Pensoft to the SIBiLS database.
What this means is that users at SIBiLS – be it human or AI – have now gained access to advanced text- and data-mining tools, including AI-powered factoid question-answering capacities, to query all this full-text indexed content and seek out, for example, species traits and biotic interactions.
To index and directly feed the content from its 40+ academic outlets at SIBiLS, Pensoft relies on advanced and full-text TaxPub JATS XML journal publication workflow, powered by the ARPHA publishing platform. Meanwhile, Plazi uses its GoldenGate text- and data-mining software to harvest taxon treatments from over 80 journals stored at TreatmentBank and the Biodiversity Literature Repository, and then further re-used by GBIF, OpenBiodiv and now by SiBILS.
Seen as a pilot, the indexing – the partners believe – could soon be extended with other journals relying on modern publishing or converted legacy publications.
However, there were still gaps left to bridge before SIBiLS could indeed be dubbed “the Biodiversity PMC”, and those have mostly been about volume and breadth of content. While the above-mentioned five journals by Pensoft had long been indexed by SIBiLS through harvesting PMC, those had been quite an exception since, several years ago, a reorganisation at PMC moved the focus of the database to almost exclusively biomedical content, thus leaving biodiversity journals out of the scope of the database.
In the meantime, while Plazi has been feeding SIBiLS a growing volume of taxonomic treatments and visual data, as it was exponentially increasing the number of publishers and journals it mined data from, a lot of biodiversity data (e.g. genetic, molecular, ecological) published in the article narratives that were not taxon treatments could not make it to the portal.
“We all know the advantages and practical uses PMC offers to its users, so we cannot miss the opportunity to incorporate this well-proven approach to navigate the data deluge in biodiversity science. Undoubtedly, it is an extremely ambitious and demanding task. Yet, I believe that, at the BiCIKL consortium, we have made it pretty clear we have the necessary expertise, know-how and aspiration to take on the challenge,”
said Prof. Lyubomir Penev, founder/CEO at Pensoft and project coordinator of BiCIKL.
“For far too long, scientific knowledge about biodiversity has been imprisoned in a continuously growing corpus of scientific outputs, which – most of the time – are published in unstructured formats, such as PDF, or as paywalled content, and often locked by both! This means that they are – at best – difficult to access and comprehend by computer algorithms. In the meantime, we need all that knowledge, in order to accelerate our understanding of the dynamics of the global biodiversity crisis and to efficiently assess the impact of climate change. This is why the need for advanced workflows and tools to annotate, mine, query and discover new facts from the available literature is more than obvious,”
added Dr. Donat Agosti, President at Plazi.
“In the course of the BiCIKL project, at SIBiLS, we started indexing a larger set of biodiversity-related contents in the broad sense, including environmental sciences and ecology, to build a new literature database, or what we now call ‘Biodiversity PMC’. Now, with the help of Plazi and Pensoft, we provide a unique entry point to half a million taxonomic treatments, which were not included into the original PubMed Central. Next on the list is to expand our network of literature sources and continue this exponential growth of queryable biodiversity knowledge to turn Biodiversity PMC into the “One Health” library. We promise to keep you posted,”
said Dr. Patrick Ruch, Group Leader at SIB and Head of Research at HES-SO, HEG Geneva, Switzerland.
SIB is an internationally recognized non-profit organisation, dedicated to biological and biomedical data science. SIB’s data scientists are passionate about creating knowledge and solving complex questions in many fields, from biodiversity and evolution to medicine.
