Pensoft publishes the collection of abstracts for LTER Bulgaria 20th anniversary conference

The “sea capital” of Bulgaria, the city of Varna, hosted a very special occasion during the past week – an international conference marking the 20th anniversary of the LTER-BG network. Over the past two decades, its members have been dedicated to establishing roadmaps and infrastructures for generating, consolidating and sharing ecosystem research data across the Balkan country and beyond.

In celebration of this milestone, members of the wider eLTER community, encompassing the whole of Europe, contributed to a three-day agenda packed with progress updates, innovative showcases and meaningful discussions on the past and future of long-term ecosystem, critical zone and socio-ecological research.

Impressed by the statements of engagement made by young scientists within the eLTER community, the Pensoft team supported the organisers’ idea to provide an Early Career Scientist Award, which granted its recipient a free publication in the One Ecosystem journal.

Following a unanimous vote by the  dedicated jury members Svetla Doncheva, Vesela Evtimova, Elena Todorova and Alexandra Tzvetkova, early career researcher Sabica Naz from the Slovak Academy of Sciences was selected as the winner. She distinguished herself with the presentation “Impacts of pre-season climatic and functional drivers on the spring onset of phenocam-derived GCC”. 

As the official communication partner of eLTER and its affiliated projects, Pensoft provided dissemination materials by eLTER RI at the dedicated booth where attendees also had the opportunity to familiarise themselves with the company’s wider publishing and research project portfolio.

At the booth, participants could get acquainted with Pensoft’s wider scientific journal portfolio. With One Ecosystem and Nature Conservation covering ecosystem science and conservation practices, NeoBiota focuses on biological invasions and Advances in Pollinator Research dedicated to all things pollinator science. Individual-based Ecology publishes research on individual-level ecological processes while the Biodiversity Data Journal supports the publication of biodiversity data. Alongside these, Research Ideas and Outcomes offers a platform for sharing research across the whole project cycle, from proposals to final results.

During the opening panel, Alexandra Tzvetkova, part of the Pensoft team working for eLTER RI, welcomed the participants, reminded them to start sharing the special collection of abstracts with their networks and highlighted the innovative propositions from Pensoft that were about to be presented in the next days and could be very useful for the eLTER community in the future – Scientiana and ORPHO.

Further, two Pensoft presentations were delivered as part of the thematic session “Emerging Technologies in Ecosystem Research, Data Management and Open Science in LTER”, and brought the audience closer to the publisher’s vision for the future:

Senior Communications Officer Peter Bozakov delved into the forthcoming science communication platform for research projects Scientiana. Launching in early 2027, it is set to be a portal for consolidating knowledge, mapping out collaborations and innovating outreach in the context of past, present and future scientific initiatives at all scales.

While, Events and Marketing Coordinator Victoria Stoyanova explored the new frontiers that an AI-FAIR outlook unveils in the domain of academic publishing. Specifically, she showcased the evolution of the ARPHA platform and the newly launched ORPHO, Pensoft’s next-gen collaborative writing tool, as examples of innovation placed directly in the hands of authors.

Together, ARPHA and ORPHO support the entire manuscript workflow from submission to publication, with structuring, taxon tagging, classification, and data publication  taking place as part of the publication process itself.

The presentations proved themselves a stepping stone to further discussions on potential collaborations with scientists, conversations that were bolstered by on-site demonstrations of the tools in question.

The conference in Varna was enjoyable, fruitful and full of hope and esteem for the better future of long-term ecosystem research. And our Pensoft team left with many ideas and an affirmed ambition to keep working to provide better solutions and services for the development of European science. What we will always remember are the words of our host – the national coordinator of LTER Bulgaria in the past 20 years, Svetla Doncheva-Bratanova: 

I would like to thank the Pensoft team for the wonderful participation in the conference. You are amazing and I am certain we could do wonders together!

Many thanks to the Bulgarian LTER community and the wider eLTER community for bringing together so many passionate researchers and making these past few days special.

Iris patterns offer a non-invasive way to recognise individual Amazonian treefrogs

Researchers in French Guiana demonstrate that the golden eyes of a Neotropical treefrog can replace invasive marking techniques.

Identifying individual animals in the wild has long meant tagging, branding or clipping. For amphibians, the standard approach has often been toe-clipping, a procedure that can affect survival, physiology and behaviour.

A new study suggests that, for at least one species of treefrog, nature has already provided a more humane solution: the eyes.

Published in the open-access journal Herpetozoa, the research was led by Dr Mélissa Peignier and colleagues at the Division of Behavioural Ecology at the University of Bern, with contributors from the Institute of Electronic Music and Acoustics at the University of Music and Performing Arts in Graz.

The team examined Osteocephalus oophagus, an Amazonian treefrog whose golden irises are crossed by fine black radial lines, forming a pattern reminiscent of a human fingerprint.

Fieldwork took place over three rainy seasons, from 2021 to 2023, on a river island of roughly five hectares in the Nouragues Nature Reserve in French Guiana. Across 392 captures, the researchers identified 103 individual frogs.

On later encounters, they photographed each animal’s eyes without touching it and compared the images with a reference library held on a rugged tablet. Frogs recognised in this way were simply left undisturbed. The identifications were independently verified using Wild-ID, a software package for photographic mark-recapture analysis.

The iris patterns proved highly distinctive. Within a single season, between 56% and 80% of frogs were recaptured and reliably re-identified, showing that the patterns are stable enough for short-term monitoring. Photographs could even be taken of frogs in amplexus, the mating embrace, without disrupting them.

The project began with simple admiration.

“At the time, I was doing my PhD, studying Allobates femoralis in the field in French Guiana. My first reaction was simply something along the lines of, ‘Wow, what beautiful eyes!’ That initial curiosity gradually turned into a genuine interest in the species, and I realised how little we actually know about them.”

The team’s motivation was also ethical.

“Other studies have used toe-clipping, which involves removing some of the digits. Personally, I was uncomfortable with this approach, especially given that these are arboreal frogs that rely on their limbs to climb trees.”

Dr Peignier

Dr Peignier hopes the method will spread.

“In a world where biodiversity is declining at an alarming rate, it is essential that we minimise our impact on the animals we study.

If we can reliably identify individuals using naturally occurring features, we may be able to reduce the need for more invasive marking techniques while still collecting the data needed to answer important scientific questions.”

The authors stress that suitability will vary between species, and that the approach should be tested case by case before wider adoption. Even so, they see considerable promise for amphibians with complex irises.

Fieldwork, Dr Peignier adds, had its own rewards.

“Honestly, the frogs themselves are incredibly beautiful and surprisingly chill, which makes working with them a real pleasure.”

Genomic study uncovers a new lace bug species on Japan’s remote Ogasawara Islands

Analysing 52 specimens with a genetic method known as MIG-seq, the team found that an insect previously regarded as a single species, Omoplax desecta, in fact comprised two.

Researchers have used genome-wide DNA data to identify a new insect species on the Ogasawara Islands, a remote Japanese archipelago roughly 900 to 1,000 kilometres south of Tokyo. The findings suggest that evolution among island insects is more intricate than appearances imply. The study is published in the open-access journal ZooKeys.

The Ogasawara Islands are a UNESCO World Natural Heritage site, celebrated for their endemic land snails and plants. Their insects, of which some 440 endemic species are known, have received far less evolutionary attention.

Jun Souma, of Hirosaki University’s Shirakami Research Center for Environmental Sciences, and Naoyuki Nakahama, of the Graduate School of Agriculture at Osaka Metropolitan University, examined Omoplax, a genus of lace bugs found nowhere else and thought to have diversified rapidly across the islands.

Analysing 52 specimens with a genetic method known as MIG-seq, the team found that an insect previously regarded as a single species, Omoplax desecta, in fact comprised two. Populations on the Chichijima and Hahajima island groups were genetically distinct, and subtle differences in male genitalia confirmed the split. The Hahajima population is now described as Omoplax sandoru, named after the local name of its host plant.

Souma was first drawn to Omoplax desecta by its unusual diet:

“The reason I took a particular interest in Omoplax desecta is that it feeds on both the native plant Rhaphiolepis indica var. tashiroi and the introduced plant Calophyllum inophyllum in the Chichijima island group.

This is quite unusual for lace bugs, which typically exhibit high host specificity. I was also intrigued by the fact that it is distributed across multiple island groups, which is different from other Omoplax species.”

The Hahajima population posed its own puzzle:

“I had wondered why it fed exclusively on Rhaphiolepis indica var. tashiroi and why there were no individuals with dark brown to black pronotum, which are sometimes seen in the Chichijima island group.

After conducting population genetic and phylogenetic analyses, I began to suspect that this population might be a distinct species. Upon closely observing their morphological characteristics, I was certain of this.”

The evolutionary tree also overturned expectations:

“The most surprising finding of my research was that species feeding on the same plant and appearing very similar are not necessarily sister groups.

Adaptive radiation among insects on oceanic islands may be more complex than comparisons of morphological characteristics and life histories would suggest at first glance.”

The results point to both geographic isolation and shifts between host plants as drivers of speciation.

Of particular interest is the insect’s adoption of Calophyllum inophyllum, a tree introduced by people. The data indicate that this host shift occurred once, and recently.

“I also find it interesting that the introduction of Calophyllum inophyllum by humans may have led to a budding of future speciation in Omoplax desecta.”

The authors note that DNA could not be obtained from two rare species, leaving parts of the story unresolved. Further sampling will be needed to trace how these insects reached the islands and diversified.

New special issue highlights threatened fish of European wetlands

A recently published special issue in the journal Nature Conservation is dedicated the unique and highly specialised fish and their importance for the conservation of wetlands in Europe.

At first glance, muddy, low-oxygen waters seem unattractive. For some highly specialized fish species, however, they are vital refuges. It is precisely these habitats that are increasingly threatened in Europe.

A new special issue in the journal Nature Conservation, recently published and edited by an expert group led by Josef Wanzenböck, is dedicated to these unique fish and their importance for wetland conservation.

The special issue “Biology and conservation of wetland fishes in Europe” brings together selected papers from the international conference “The Fish of Muddy Waters,” which took place in Vienna in October 2025. The focus was on fish species adapted to the specific conditions of wetlands and their surrounding areas.

These include, among others, the European mud minnow (Umbra krameri), the weatherfish (Misgurnus fossilis), and the crucian carp (Carassius carassius). At the same time, non-native fish species that have since become established in the peripheral areas of floodplains and other wetland habitats were also examined, and their impact on ecosystems was discussed.

What makes these fish special is their ability to cope with conditions under which many other species could not survive. In small, muddy bodies of water, oxygen levels can be very low at times. The fish species found there are adapted to these extreme conditions and can therefore provide important insights into the state of their habitat. This means that fish inhabiting wetlands are much more than just rare species. They can serve as indicators of the ecological health of their habitats. If these specialized fish are struggling, this often points to changes or a deterioration in the entire ecosystem.

For instance, a study by Sallai et al., covers 50 years of records from Hungary, the core of the European mud minnow’s range, found that the species has disappeared from 44% of its historically known localities. Its lineage is roughly 60 million years old, yet surviving populations are increasingly confined to artificial canals. In the research article, drying wetlands emerged as the clearest threat.

The issue also offers cause for hope. Bajomi and col. showed that in two small, isolated artificial ponds, mud minnows released by conservation teams were still breeding 7 to 10 years later, which shows that carefully designed translocations can create safe refuges for the European mudminnow (Umbra krameri).

This was precisely the focus of the conference “The Fish of Muddy Waters.” The goal was to strengthen the link between research and conservation and to draw attention to fish species that often receive less public attention than larger or economically more significant species. The exchange between international scientists and representatives of nature conservation organizations should help to consolidate existing knowledge and develop new approaches to the protection of endangered wetland fish.

Fish have always held a firm place in our culture and are closely linked to the use of water bodies. However, the little-known inhabitants of wetlands reveal another side of this relationship: they highlight just how closely the conservation of individual species is tied to the protection of their habitats. Research on these species can thus also help raise awareness of the importance of wetlands and lay the groundwork for more effective biodiversity conservation.

This newly published special issue offers insight into current research on these specialized fish species and makes selected results of the Vienna conference accessible to an international audience of experts.

Three New Species of Conger Eel Discovered in the Deep Waters Around Taiwan

Researchers have now described three new species of the conger eel genus Gnathophis, drawing on 130 specimens collected from the deep sea.

Researchers from National Taiwan Ocean University, University of Taipei and the Smithsonian Institution have now described three new species of the conger eel genus Gnathophis, drawing on 130 specimens collected from the deep sea. The findings raise the number of Gnathophis species known from Taiwan from two to five.

Members of this genus are medium-sized eels of tropical and subtropical deep waters, recognisable by a blunt tail tip, a fleshy snout that projects beyond the teeth, and a small fleshy keel on the underside of the snout.

The team compared vertebral counts, the pores of the sensory lateral line, colouring and tooth patterns, and for two of the species they added DNA barcoding to confirm the distinction. The two barcoded species differ from each other by roughly 4.4 to 4.9 per cent in the gene examined, well beyond the variation seen within a single species.

Each name tells a small story about where the eel was found or how it looks:

  • Gnathophis kbalanensis (Kbalan’s conger): named after “Kbalan”, an ancient name for the Yilan region of northeastern Taiwan, in use roughly 800 to 1,300 years ago. It is also known as Cabaran in Spanish and Kat-má-lán in Taiwanese. The largest specimen measured 472 millimetres, and the species is recognised by its blackish fins and a high vertebral count of 134 to 137.
  • Gnathophis melanurum (black tail conger): named from the Greek melan, meaning black, and urum, meaning tail, in reference to its black tail fin. Its dorsal and anal fins are pale, which makes the dark tail stand out. It was found off both northeastern and southwestern Taiwan, mostly at depths of around 200 to 300 metres.
  • Gnathophis nanhaiensis (Nan Hai’s conger): named after “Nan Hai”, the Chinese name for the South China Sea, where the holotype was collected at a depth of about 509 metres. The Latin ending -ensis means “originating in”. Known from only two specimens, it has pale fins and the highest vertebral count of the three, at 139 to 143.

  • Gnathophis melanurum sp. nov. Jian-Fu Huang, et al.
  • Gnathophis nanhaiensis sp. nov. Jian-Fu Huang, et al.

The first two species share a feature that sets them apart from some of their relatives: the lateral line pores above the pectoral fin are raised, and the peritoneum, the lining of the body cavity, is black. Several of the specimens were ripe females carrying loose eggs, which suggests these waters may serve as spawning grounds.

The study also tidies up the regional record. An eel previously listed in Taiwan as Gnathophis xenica was confirmed to be a misidentification, and the researchers found no evidence to split the widespread G. heterognathos into separate species.

The work is dedicated to the late Dr David G. Smith, whose contribution to eel taxonomy inspired the first author.

A Blind Snake on the Roof of the World: New Burrowing Species Discovered Beneath the Stones of the Qinghai-Xizang Plateau

Scientists from Yibin University and collaborating institutions have formally described Indotyphlops gyirongensis, the Gyirong blind snake.

High on the Qinghai-Xizang Plateau, often called the “Roof of the World,” a new species of snake waits beneath the stones…

Scientists from Yibin University and collaborating institutions have formally described Indotyphlops gyirongensis, the Gyirong blind snake, a discovery that adds a new member to one of the least understood branches of the snake family tree.

General (top) and ventral (below) views of the holotype of Indotyphlops gyirongensis sp. nov. in life (by Peng Guo).

Blind snakes are small, burrowing reptiles that spend nearly their entire lives underground. Their secretive habits and similar appearances make them notoriously difficult to study.

The family Typhlopidae contains roughly 280 species, yet its relationships remain poorly resolved, and new species continue to surface wherever researchers look carefully. Until now, no blind snake had ever been recorded in the Xizang Autonomous Region, which makes this find a first for the area.

The single specimen, an adult female, was collected in August 2025 at an elevation of 2,262 metres, close to the border between China and Nepal. She was resting beneath a stone at the edge of an evergreen broad-leaved forest, where deep humus and a thick layer of fallen leaves create ideal conditions for a creature that lives by burrowing. Among her neighbours were a Himalayan pit viper and a Himalayan toad!

Microhabitat of the type specimen of Indotyphlops gyirongensis sp. nov. in Gyirong, Xizang, China (by Peng Guo).

The snake itself is slender and elegant. At 265 millimetres, it is large by the standards of its genus, yet it measures just 3.5 millimetres across at midbody. Its glossy scales are light brown, each one darker on its rear half, which gives the body a delicate and finely patterned sheen. The underside is cream and so thin-skinned that it is partly transparent to the internal organs.

Most distinctive is its pale cream head cap, which lacks pigment as far back as the eye. The eye itself is only a dark spot, with no visible pupil or iris, fitting for an animal that navigates by touch and chemical cues rather than sight. Its tail ends in a small nubbin rather than a sharp spine.

Some of the most telling differences are hidden in the arrangement of the scales along the lip. Blind snakes are classified partly by how their upper lip scales overlap the shields above them. In nearly all of the snake’s relatives, the third scale overlaps the one beside the eye, a pattern known as T-III.

The Gyirong blind snake shows a rarer arrangement, called T-V, in which both the second and third lip scales overlap the shields above. Few documented members of its genus share this feature, which provides a clean and reliable way to separate it from most of its kin.

Anatomy alone did not settle the matter. The team sequenced two mitochondrial genes and placed the snake within a broad evolutionary tree. It nested firmly within Indotyphlops, as the sister lineage to I. albiceps, but its genetic divergence was substantial. For one gene, it differed from its closest relatives with available data by more than 24 per cent, and for another by more than 18 per cent, margins far beyond what is typically seen within a single species.

The name honours the place of discovery. Gyirongensis refers to Gyirong Town in Gyirong County, where the holotype was found, and it is formed as a noun in apposition. The authors propose the English common name “Gyirong blind snake” and the Chinese name 吉隆盲蛇 (Jílóng Mángshé).

Map showing the locality of the new species in Gyirong, Xizang, China.

Because the type locality sits so close to the Nepalese border, the researchers consider it highly likely that the species also lives on the other side, thus pending further fieldwork.

Pensoft at TDWG2026: Pushing the boundaries of innovation in biodiversity data management forward

Last week marked another annual meeting of the Biodiversity Information Standards network, otherwise known as TDWG, with the Norwegian capital Oslo hosting the event between 20 and 25 September.

Last week marked another annual meeting of the Biodiversity Information Standards network, otherwise known as TDWG, with the Norwegian capital Oslo hosting the event between 21 and 25 September.

TDWG is the international, non-profit organisation formerly known as the Taxonomic Databases Working Group, which develops and maintains the standards, such as Darwin Core, that allow biodiversity data to be shared, integrated and understood across institutions worldwide.

The six-day programme was a meeting point for over 300 stakeholders from research, practitioner and corporate circles, with proceedings centred around one central topic – “Research and Robot-Ready Biodiversity Data Standards”. In that sense, the themes of accessibility, responsibility, innovation and collaboration were foremost on the minds of participants as they contemplated how information on the biosphere should be extracted, consolidated and shared in the years to come.

As a long-standing partner of TDWG, Pensoft Publishers served as both a sponsor and an exhibitor for the event. In the latter capacity, the company contributed with a joint booth for three of the EU-funded projects it is leading the outreach efforts for:

  • BMD – an initiative working towards a Biodiversity Explorer for high-throughput biodiversity monitoring tools, biodiversity data and biodiversity analyses for better conservation across Europe
  • TETTRIX – a new arrival building a next-generation taxonomic system connecting knowledge, expertise and innovation for all across the Old Continent
  • ANERIS – a pan-European effort to mobilise a network of operational marine biology via a new technological infrastructure
The Pensoft team at the joint booth of the BMD, TETTRIX and ANERIS projects.

A number of other projects from Pensoft’s communication portfolio also found a place in the display, including BEAGLE, OneSTOP, B-Cubed, MAMBO, OBSGESSION and BioAgora. Furthermore, 14 of the company’s journals were in the spotlight, including Biodiversity Information Science and Standards (BISS), the official journal of the TDWG community (where all of the conference’s abstracts are set to be published).  

Crucially, the event also saw the official launch of ORPHO, Pensoft’s new collaborative workspace for scientific writing. Founder and CEO Prof. Lyubomir Penev and CTO Teodor Georgiev conducted live demos of the tool, showcasing how manuscripts crafted within it with full version control for authors become discoverable, interoperable and FAIR-compliant.

In the context of TDWG2026’s agenda, they also presented ORPHO’s integrated semantic annotation and communication instruments as part of the workshop “How Literature Services can Support & Benefit from Biodiversity Publication and Data Standards?” on 24 September. The workspace was received with anticipation and enthusiasm by attendees, with many expressing a desire to test it out for themselves.

They were also treated with a tease of Pensoft’s next large-scale endeavour, as Senior Communications Officer Peter Bozakov pulled the curtain behind the forthcoming communication platform for research projects Scientiana.

As for other notable contributions to the wider conference agenda by researchers affiliated with Pensoft’s publishing or project activities:

  • The session “Operationalising Biodiversity Digital Twins within Data Space Ecosystems”, which was co-led by BMD coordinator and long-time author and reviewer across several Pensoft journals, including Biodiversity Data Journal and Research Ideas and Outcomes, Niels Raes, and showcased a number of innovative outputs from the project. As such, it was an important occasion to assess the initiative’s progress towards unifying Europe’s Data Space within a single Biodiversity Explorer.

  • The symposium “Publishing and Communications Promoting Biodiversity, Natural History Collections, People, Data and Data Standards”, for which Deborah Paul (co-Editor-in-Chief of the Natural History Collections and Museomics (NHCM) journal) had the role of co-organiser. Within it, the TETTRIX project’s vision for the automated tracking of taxonomic research activities was laid out by consortium member David Fichtmüller. Moreover, Shelley James (co-Editor-in-Chief for NHCM) delivered an insightful talk on the creative promotion of biodiversity data and standards for success and recognition.

Notably, the Biodiversity Information Science and Standards (BISS) journal is the home for TDWG conference abstracts. TDWG 2026 presenters can currently submit their abstracts there and publish them in an extended abstract or mini-paper format completely free of charge. The journal also hosts abstracts from conferences held over the past decade. You can browse the TDWG 2026 collection here.

Last but not least, the company’s sponsorship supported two awards at TDWG2026 (with a free publication in a Pensoft journal as an accompanying prize):

  • Best Student Oral Presentation – awarded to Yeshan Qui for “Reporting structure and sampling-bias correction in citizen-science bird data across Asian cities”
  • Best Student Poster – awarded to Claudia Campanini for “Improving marine fieldwork documentation and metadata with Adaptable Standardised Methods Reporting (ASMR)”
Claudia Campanini receiving the Pensoft Best Student Poster Award at TDWG 2026.

Overall, TDWG2026 proved itself a crucial forum for mapping out the future of biodiversity monitoring and the management of the myriad data streams that emerge from it. Pensoft is proud to be an important actor in this process, contributing with innovative tools and solutions at the heart of the interface between research and practice. As summarised by Prof. Penev:

“Given its status as a large-scale conference centred around the future of biodiversity sciences in the age of AI, TDWG2026 was a crucial venue for unveiling Pensoft’s forward-looking vision for academic publishing and science communication. The “pearl” of these pursuits is undoubtedly the ORPHO workspace, a tool that is well-placed to introduce a new standard when it comes to collaborative AI-FAIR research in Europe and beyond.”

New click beetle species named after Dominican Republic’s Indigenous Arawak people

Lissomus arawak measures under a centimetre long and is easily recognised by its shining and almost hairless black body, alongside its pale-yellow antennae segments.

A new species of click beetle with a glossy and highly domed black body has been described from cloud forest sites in the mountains of the Dominican Republic, and named in honour of the Arawak peoples who lived on the island before European colonisation.

Lissomus arawak measures under a centimetre long and is easily recognised by its shining and almost hairless black body, alongside its pale-yellow antennae segments. It is only the third species of the genus Lissomus known from Hispaniola, and the third recorded anywhere in the Greater Antilles.

The study, published in the open-access journal Alpine Entomology, was carried out by Paul J. Johnson of South Dakota State University and Jiri Hodecek of the Swiss Human Institute of Forensic Taphonomy, as part of an ongoing survey of Dominican insect life. Specimens were found at three sites in montane broadleaf and cloud forest between roughly 600 and 700 metres, near the Sierra de Bahoruco and in the Cordillera Septentrional.

Rather than resembling the two other Lissomus species already known from Hispaniola, the new beetle turned out to be structurally closer to species from Central and northern South America.

“The morphological differences suggest that the Lissomus species of Hispaniola may not all descend from a single colonisation event.

One possible explanation is therefore that ancestors of these beetles reached the Greater Antilles on at least two separate occasions. This remains a testable hypothesis rather than a demonstrated evolutionary history.”

The Research Team

The species is known from just five specimens, collected individually between 1985 and 2024, all of them female.

“With such a small sample, chance and the opportunistic nature of the collecting are probably the simplest explanations. This does not seriously weaken our confidence that L. arawak is distinct. All five females share a consistent and unique combination of morphological characters.”

Type locality of Lissomus arawak in Pedernales province (el. 700 m).

The name is a deliberate tribute to the island’s first inhabitants:

“We chose the name arawak to recognise the Indigenous history and continuing cultural heritage of the Antilles. We wanted the name of this distinctive endemic species to connect the biological history of the island with its human history.”

The discovery forms part of a wider effort, they added, “to document the island’s still incompletely known insect diversity,” with at least 15 further click beetle species thought to await description in the Dominican Republic alone.

The discovery forms part of EntomoDR, a long-term field and taxonomy project documenting the still incompletely known insect diversity of the Dominican Republic through repeated expeditions and collaboration with an international network of taxonomic specialists.

Pensoft at the Nordic Oikos-GfÖ 2026 conference: Integrating the Diversity of Ecology

Between 13-17 September 2026, Pensoft Publishers joined the Nordic Oikos-GfÖ 2026 conference in Odense, Denmark.

Between 13-17 September 2026, Pensoft Publishers joined the Nordic Oikos-GfÖ 2026 conference, jointly organised by the Nordic Society Oikos and the Ecological Society of Germany, Austria and Switzerland (GfÖ) in Odense, Denmark.

Themed “Integrating the Diversity of Ecology”, the event welcomed over 1,000 researchers in the field from across career stages, who had the opportunity to enjoy conference talks across 36 thematic sessions, as many as six keynote talks, two poster sessions, several open society meetings and quite a few social events, including excursions and a conference dinner. 

Conference delegates enjoying the musical clock installation mounted on an elevated balcony on the glass façade of the ODEON building, where the Nordic Oikos-GfÖ 2026 conference took place between 13 and 17 September 2026.

Throughout the scientific event, conference delegates had the opportunity to also explore the various publishing services offered by Pensoft to authors of research, journal managers, conference organisers; the diverse portfolio of almost 100 open-access peer-reviewed journals published on Pensoft’s ARPHA Publishing Platform.

Beyond publishing solutions, a key focus was given to OBSGESSION: a Horizon Europe-funded project where Pensoft is actively involved. To better understand and predict changes in terrestrial and freshwater ecosystems, the OBSGESSION consortium integrates multi-source Earth Observation data (such as high-resolution satellite imagery and drone monitoring) with ground-based in-situ research, including advanced environmental DNA (eDNA) sampling. By coupling these data streams with cutting-edge detection-attribution modelling and machine learning algorithms, the project generates scalable Essential Biodiversity Variables (EBVs). These ecological approaches and analytical frameworks are actively tested and validated through six biodiversity pilots across diverse European ecosystems. In the open-science Research Ideas and Outcomes journal, you can find a collection of project outputs, including research papers, project reports and deliverables, and guideline papers published across journals and platforms.

At the Pensoft-OBSGESSION-branded booth, conference participants would stop by to chat with Pensoft’s Head of Journal development and PR: Iva Boyadzhieva and Senior Communications Officer: Desislava Raykova.

As a leader of the “Dissemination, Multi-stakeholder outreach and synergies” work package at OBSGESSION, Pensoft is tasked with stakeholder engagement and community building, ultimately contributing to the high impact of the resulting outputs, methodologies and policy recommendations that aim to strengthen public understanding of biodiversity change.

One of the six keynote talks was presented by Prof. Dr. Isabell Hensen (Martin Luther University Halle, Germany), who received the GfÖ Honorary Medal 2026 for her leading, forward-looking contributions to ecological research and the scientific community. Her work examines how genetic variation, environmental conditions, disturbance, and plant-animal interactions shape plant populations, with particular emphasis on rare species, biological invasions, and the regeneration of degraded forests.

In her talk, titled “One spark is enough: regeneration ecology of Andean forests under global change”, she reported on post-fire regeneration processes in tropical Andean forests, based on long-term field experiments and observational studies. 

Hensen focused on the well-studied endemic plant genus Polylepis, which forms the world’s highest-elevation forests and illustrates how fire has shaped ecosystem dynamics over millennia. Her talk also mentioned a 2022 monograph of the genus, published in the Pensoft journal PhytoKeys by Tatiana Erika Boza Espinoza (Pontificia Universidad Católica del Perú) and Michael Kessler (University of Zurich), which brought together results from 35 years of field and herbarium experience.

On Wednesday, Pensoft’s Iva Boyadzhieva delivered a presentation titled “Scholarly Communication: Lessons from the Publisher’s Kitchen”. She highlighted the vital role publishers play in helping researchers communicate their insights not only to peers, but also to decision-makers and the public. Emphasizing the publisher’s responsibility to support authors with robust infrastructure and dedicated human expertise, she outlined how Pensoft works to FAIRify scholarly publishing and future-proof scientific knowledge in an era of rapid AI development and expanding research output.

*

Pensoft’s team was delighted to meet up with dedicated readers, authors, reviewers, and editors from across Pensoft’s portfolio, as well as introduce Pensoft journals to attendees discovering them for the first time.

Unsurprisingly, well-established society journals published by Pensoft, such as Frontiers of Biogeography, NeoBiota, Vegetation Classification and Survey, Vegetation Ecology and Diversity and Italian Botanist drew plenty of attention, alongside long-standing Pensoft’s own titles like Nature Conservation, PhytoKeys, One Ecosystem and the Biodiversity Data Journal. 

Visitors were also particularly intrigued by several newly launched Pensoft journals. Developed in close collaboration with passionate researchers, these fresh outlets directly address key gaps in academic publishing. 

One of the newly launched journals in the spotlight was Agricultural and Environmental Modelling (AEM), which provides a unique scholarly outlet thanks to its modern approach to publishing by increasing transparency, giving credit to research objects across the entire modelling research lifecycle. This is achieved through publishing specialised article types, such as: Formal Model, Model Testing and Calibration, Model Implementation and Documentation, Data Papers and Software Descriptions. These new publishing formats are designed to keep pace with advances in Modelling research and to make it FAIR (Findable, Accessible, Interoperable, and Reusable) by enabling scholarly credit for diverse research outputs, often created by different groups of authors. For the time being, AEM remains a Diamond Open Access journal, meaning that it will not charge authors for open-access publication. 

Other recently founded journals addressing emerging and fast-developing disciplines within the ecological field that took the spotlight were:

  • Individual-Based Ecology: launched to support understanding and predicting ecological systems’ response to rapidly changing and novel conditions by linking individual responses to responses at higher levels of organisation.
  • Advances in Pollinator Research: a multidisciplinary journal publishing research on pollination ecology, pollinator-plant interactions, pollinator health and drivers of pollinator declines, crop and wild flower pollination, pollinator conservation practices, molecular ecology of pollinators, pollinator and pollination monitoring, decision support for policy and socio-economics.
  • Journal of Regeneration: a multidisciplinary journal for the dissemination of research results on regeneration and tissue repair across phyla. These mechanisms can be framed within an evolutionary framework and integrate a variety of cellular processes involving stem cells, dedifferentiating or even transdifferentiating cells. 

All of these journals operate with no article fees for either authors, nor readers.

Supporting European Policy Through Priority Essential Biodiversity Variables (EBVs)

Delegates at the event showed strong interest in OBSGESSION’s first policy brief: “Prioritising Essential Biodiversity Variables (EBVs) to support European Union (EU) policy needs based on the EU’s Biodiversity Strategy for 2030.” To tackle a critical challenge in environmental monitoring, OBSGESSION focuses on prioritising key EBVs to directly support the EU Biodiversity Strategy 2030 – a roadmap designed to put Europe’s biodiversity on a path to recovery through 102 specific actions and sub-actions.

To align these policy needs with actionable data, the OBSGESSION team conducted an assessment to identify priority EBV candidates. By categorising EBV-applicable actions and indicators across different ecosystem realms and implementation stages, the project pinpointed the most essential variables needed to strengthen monitoring, reporting, and policy execution. The document is based on a deliverable by the project (D1.1 Policy Landscape and Needs Assessment).

This policy brief is part of a broader, ongoing effort within OBSGESSION to bridge the gap between biodiversity data and policy execution. To dive deeper into the science behind this topic, the project has hosted a dedicated seminar series exploring key aspects of the framework:

Bringing Methodologies to Life Across European Ecosystems

Beyond theoretical frameworks, OBSGESSION grounds its research in six biodiversity validation pilots across Europe. The case studies represent European biodiversity and ecosystem conservation challenges at scales varying from local to regional. Full details on each ecosystem pilot are now available in a collection of newly published pilot factsheets, which made their debut at the conference, where people could take a look at their digital versions. 

Reading those materials gives an insight into the practical testing environment to demonstrate how Earth observation, field research, and ecological modelling come together to deliver actionable biodiversity insights. You can also check out OBSGESSION’s biodiversity pilots on the project’s website.

The OBSGESSION in a Nutshell video presents a concise overview of the project’s overarching mission and components.

Pensoft at the European Small Mammal Conservation Conference 2026

The inaugural conference took place in Sofia, Bulgaria, bringing together researchers, conservationists and practitioners to address gaps in small mammal research and monitoring. 

The inaugural European Small Mammal Conservation Conference (SMCC 2026) took place in Sofia, Bulgaria, from 21 to 25 September 2026, bringing together researchers, conservationists and practitioners from across Europe and beyond to address gaps in small mammal research and monitoring. 

Table of Contents

Organised jointly by the Habitat Foundation, the Institute of Biodiversity and Ecosystem Research at the Bulgarian Academy of Sciences, the Dutch Mammal Society and Mammal Conservation Europe, with support from the Faculty of Biology at Sofia University, the conference formed part of the Life for Falcons project, funded by the EU LIFE Programme.

This year’s conference was held jointly with the 33rd Hamster Working Group and the VIII European Ground Squirrel Meeting, making hamsters and sousliks the primary focus, alongside broader topics including renewable energy development, agricultural impacts, reintroductions, predator–prey interactions and innovative methodologies in small mammal research.

Pensoft’s Participation

We were delighted to participate in SMCC 2026 with an exhibition booth, showcasing the breadth of publishing services we offer to the biodiversity and conservation community. It was a pleasure to present our portfolio of journals dedicated to advancing research across ecology, biodiversity and conservation.

  • Pensoft’s booth at SMCC 2026.

We were particularly proud to present the following journals:

Conference Highlights

The scientific programme was exceptional, and we were privileged to attend many outstanding presentations that demonstrated the importance of innovative monitoring approaches and conservation action.

Lessons from Citizen Science for Small Mammal Conservation Monitoring in Great Britain

We were delighted to attend a talk by Matt Larsen-Daw, Chief Executive of the Mammal Society (UK), which presented a portfolio of citizen science programmes designed to address distribution knowledge and population monitoring across Great Britain. The programmes, united by the Mammal Mapper smartphone app, included the National Harvest Mouse Survey, the Searching for Shrews initiative, and the University Mammal Challenge. 

The presentation highlighted the value of standardised effort data, the differing trade-offs between structured and opportunistic recording, and the potential for these approaches to be applied across European contexts.

Strong Decline of Hamster Populations in Bulgaria

We were equally impressed by Nedko Nedyalkov’s presentation documenting the significant decline in distribution and abundance of both the common hamster (Cricetus cricetus) and the Romanian hamster (Mesocricetus newtoni) across Bulgaria. The research revealed that population reductions, detected through owl pellet analysis and trapping methods, likely began in the 1950s with agricultural intensification and continue today. 

Given that both species are strictly protected under the EU Habitats Directive yet lack active conservation projects, the presentation substantiated the urgent need for targeted conservation measures. We are also pleased to note that Nedko serves as a subject editor for two of our open-access journals, ZooKeys and the Biodiversity Data Journal.

Reintroduced Saker Falcons and Their Dependence on European Ground Squirrels

Yana Andonova’s presentation on the diet of Bulgaria’s reintroduced saker falcon population provided compelling evidence of the breeding birds’ overwhelming dependence on the European ground squirrel (Spermophilus citellus) as a primary food source.

Through food-remain analysis, visual observations and camera-trap monitoring, the research documented that ground squirrels comprised over 80 per cent of identified prey items, with small rodents accounting for 89 per cent overall! It is also worth mentioning that Andonova is an author in our open-access Biodiversity Data Journal.

Looking Forward

Attending SMCC 2026 was a genuine pleasure and particularly meaningful given that the conference took place in Sofia, the city in which our company is based. Connecting with researchers and conservationists working at the forefront of small mammal conservation, and sharing our commitment to advancing biodiversity research through open-access publishing, reinforced our dedication to supporting this important field. 

We look very much forward to engaging with this community again at future events!
