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.

Pensoft Publishers has served as the communication and dissemination partner for the eLTER Research Infrastructure for the past six years. Pensoft has also always supported the activities of LTER Bulgaria.

For this 20th anniversary conference, all 55 abstracts for oral and poster presentations were organised and published in a special collection titled “Long-Term Ecosystem Research: Contributions, Challenges and Future Perspectives” on the ARPHA Conference Abstracts, and for less than a week it has already garnered over 6,000 views.

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.

Research stations across Europe presented in a photo exhibition in Sofia

The exhibition was organised by Pensoft as part of the communication and dissemination activities for the EC Horizon project eLTER (European Long-Term Ecosystem Research)

In the past months, a unique photo exhibition showcasing European long-term ecosystem research sites was presented in the Bulgarian capital: Sofia.

This visually striking exhibition was not only a celebration of science and nature, but also an illustrative example of Pensoft’s integrated approach to communication, dissemination, and community engagement under the EU-funded eLTER project.

Coordinated by Pensoft’s Communications team, the initiative demonstrates how a carefully curated campaign can be transformed into a multi-layered outreach success. From conceptualization to realization, the team worked closely with the eLTER Coordination and Head Office to create what is now known as the eLTER Grand Campaign—a journey across Europe to visually document the human and ecological stories behind the research stations.

The eLTER photo exhibition was displayed at the ‘Lover’s bridge’ in Sofia, Bulgaria.

Over the course of three months, photographer Evgeni Dimitrov and his team traveled across 23 European countries, visiting some of the continent’s most advanced long-term ecosystem research sites. Using both drone and handheld cameras, the team captured nearly 3,000 photographs and 50 videos, bringing an artistic lens to the world of environmental science. The visual materials created during the Grand Campaign will be integrated into the eLTER database, becoming a valuable resource for researchers and stakeholders across Europe. These assets will support ongoing efforts in data visualisation, educational outreach, and long-term documentation of ecosystem changes.

“During the trip, it was fascinating to observe the work of scientists—each team reflecting the specific national context, yet united by a shared goal: to collect increasingly detailed data that can help us create a better environment.

I aimed to portray the research stations not only from a technical perspective—showing the equipment and how it’s used—but also within the broader environment: the nature around them, the living beings they interact with, and the people behind the machines who bring meaning to otherwise dry data.

explained photographer Evgeni Dimitrov.

Seizing the momentum of the exhibition’s launch in Sofia, the Pensoft team also engaged with local media to broaden public awareness of the eLTER project. For example, the Bulgarian Telegraph Agency published a feature story, titled “Photo Exhibition Presents Research Stations across Europe in Sofia” in both Bulgarian and English, which highlights the exhibition, as well as the mission and goals of eLTER, with a special focus on the work of LTER-Bulgaria. Other local media also covered the news and promoting eLTER.

This strategic blend of visual storytelling, media engagement, and public outreach exemplifies Pensoft’s holistic approach to science communication.

From centrally managing a campaign, coordinating international logistics, and delivering high-quality media assets, to generating public interest and securing media coverage, this initiative shows how communication can become a vital extension of research impact.
