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.

This June, the eLTER project will be holding its very first science conference with the aim to bring together scientists across disciplines who are striving to adopt a holistic approach to the understanding of the complex interactions between living organisms, humans, and their physical environment in the critical zone.

The event will take place on 23-27 June 2025 in Tampere, Finland. Abstracts submitted to the conference will be made permanently available in the eLTER Science Conference abstracts collection in the journal-like ARPHA Conference Abstract platform.

Pensoft is a project partner and a work package leader in the eLTER projects. eLTER receives funding from the European Union’s Horizon 2020 research and innovation programme under GA No 871126 (eLTER PPP) and GA No 871128 (eLTER PLUS), and the European Union’s Horizon Europe research and innovation programme under GA No 101131751 (eLTER EnRich).

Boosting the reproducibility of research: Pensoft joins the EU-funded project TIER2

As an experienced science communicator and open-science publisher, Pensoft is joining this promising project on its mission within its acronym: Trust, Integrity, and Efficiency in Research, through next-level Reproducibility

Recent years have seen perceptions of a “reproducibility crisis” grow in various disciplines. Scientists see poor levels of reproducibility as a severe threat to scientific self-correction, the efficiency of research processes, and societal trust in research results. 

Now, a newly launched Horizon Europe-funded project: TIER2 brings together 10 major European organisations and proponents of open science to dig deeper into the issues surrounding reproducibility in research work with the aim to improve practices and policies across diverse scientific fields. 

In its capacity as an experienced science communicator and open-science publisher, Pensoft is joining this promising project on its mission within its acronym: Trust, Integrity, and Efficiency in Research, through next-level Reproducibility (TIER2).

TIER2’s interdisciplinary, expert project team will use co-creative methods to work with researchers in social, life and computer sciences, research funders, and publishers to further understand and address the causes of poor reproducibility. 

The project will produce and test new tools, connect initiatives, engage communities, and test novel interventions to increase reuse and overall quality of research results. 

“It is very exciting to take part in such significant work for the benefit of scientific rigor and integrity. As an open-access publisher, the goals of Pensoft and TIER2 are very much aligned – increasing the trust and efficiency of the research apparatus on a large scale. We are looking forward to collaborating on this mutual goal.”

said Teodor Metodiev, TIER2 Principal Investigator for Pensoft.
The project

TIER2 launched in early January 2023 and will be running until December 2025 with the support of EUR 2 millions in funding, provided by the European Union’s Horizon Europe program and the United Kingdom’s Research & Innovation

TIER2 will study reproducibility in diverse contexts by selecting three broad research areas (i.e. social, life and computer sciences) and two cross-disciplinary stakeholder groups (i.e. research publishers and funders). Reaching different contexts will allow the project team to systematically investigate the causes and implications of the lack of reproducibility across the research spectrum. Together with curated co-creation communities of these groups, the project will design, implement, and assess systematic interventions – addressing critical levers of change (tools, skills, communities, incentives, and policies) in the process.

In 3 years’ time, TIER2-led activities will have significantly boosted knowledge on reproducibility, created valuable tools, engaged communities, and implemented interventions and policies across science. As a result, the reuse of resources and the quality of research results in the European research landscape and beyond will be improved and increased, and so will trust, integrity, and efficiency in research overall.
