New Study Outlines How Countries Can Build Effective DNA Barcoding Networks

New research in Metabarcoding and Metagenomics provides a blueprint for building a robust, globally adaptable network of DNA barcoding practitioners. 

Aligning with the International Day for Biological Diversity‘s theme of “Acting locally for global impact,” researchers have released a comprehensive blueprint for building a robust, globally adaptable network of DNA barcoding practitioners.

DNA barcoding has become a cornerstone for modern species identification and biodiversity monitoring, proving vital for applications ranging from ecological research to conservation and environmental policy. Since its inception, the DNA barcoding community worldwide has been convening under the aegis of the International Barcode of Life (iBOL), which provides necessary global coordination. To implement barcoding at scale, build local capacity, and translate scientific advances into actionable practice, iBOL national nodes have been established since the 2010s

Published in the open-access journal Metabarcoding and Metagenomics, the article “Empowering national capacity for a DNA-based approach to species identification and biodiversity monitoring” by E. Kaitetzidou et al. provides strategic advice on establishing iBOL national nodes. 

Drawing on a survey and workshop conducted under the Horizon Europe Biodiversity Genomics Europe project, this research synthesises experiences from 20 countries, including 17 in Europe, and examines how national nodes are initiated, governed, and sustained. Common challenges included defining scope, securing sustainable funding, harmonising methodologies, and engaging stakeholders. For example, a particularly striking finding was how rarely node coordinators sought guidance from established networks before setting up their own.

The decision-making process and steps taken were almost entirely based on intuition and the experience from other within-country activities, as well as their perceptions of the activities of other nations’ barcoding nodes,

Central to the paper are ten practical recommendations to ensure the establishment and long-term success of national DNA barcoding nodes. The authors emphasise several key priorities, primarily the construction of comprehensive DNA barcode reference libraries and the critical need to align scientific activities with practical biomonitoring requirements.

Furthermore, they strongly advocate for promoting FAIR (Findable, Accessible, Interoperable, and Reusable) and CARE data principles, alongside implementing focused strategies for capacity building, methodological standardisation, communication, and diverse stakeholder engagement.

Stronger national infrastructures will enhance Europe’s capacity for DNA-based biodiversity monitoring and support metabarcoding and metagenomic research. Building on milestones such as the establishment of iBOL Europe in 2022, these local efforts add up to real progress on species discovery, conservation, and environmental management worldwide.

First Bulgarian DNA barcoding symposium brought over 120 researchers

The symposium took place on 5 December 2025 at the Headquarters of the Bulgarian Academy of Sciences, organised by the Bulgarian Barcode of Life.

The first national symposium on DNA barcoding took place on 5 December 2025 at the Headquarters of the Bulgarian Academy of Sciences, where it was attended by renowned Bulgarian scientists in the field, in addition to early-career researchers and PhD students representing different institutions.

The event was organised by the Bulgarian Barcode of Life (BgBOL): a national node, part of the International Barcode of Life, which was established in October 2023 by  the Institute of Plant Physiology and Genetics (BAS), Institute of Biodiversity and Ecosystem Research, National Museum of Natural History (BAS), Sofia University “St. Kliment Ohridski”, AgroBioInstitute (Agricultural Academy), University of Forestry, and Pensoft in its role of a scientific publisher and tech innovator well-known in the field of biodiversity science.

The event saw a day-long series of lectures and a poster session, during which the participants had the opportunity to get acquainted with the work of their colleagues in various fields of biology. 

Amongst the topics were the development of the Bulgarian molecular laboratory in Antarctica; the study of the invertebrate fauna currently underrepresented in DNA reference libraries; the return of the beaver to Bulgaria; and research on phytopathogenic fungi on agricultural crops.

During the coffee breaks sponsored by the National Museum of Natural History, the delegates had the chance to network and exchange experience between institutions and fields of expertise.

Teodor Georgiev, CTO at Pensoft held a presentation about the 2.0 version of the ARPHA Writing Tool. In its greatly improved version, it will feature many new, refined and elaborated workflows that help and simplify data publishing, discoverability, reusability and overall FAIRness. 

The event was opened and closed by Prof. Dr. Lyubomir Penev, who was elected as the Chair of the Governing Board at the Bulgarian Barcode of Life last year. He is also the founder and CEO of Pensoft.

In his closing speech, Penev expressed his hopes for the development of BgBOL and confirmed the plans of the consortium to turn the symposium into an annual tradition. Congratulations were extended to BgBOL’s newest member: the Institute of Oceanology “Fridtjof Nansen” at BAS. 

He also announced the launch of a new special collection in the Biodiversity Data Journal, which will welcome scientific papers related to the Bulgarian and Balkan biota and using DNA barcoding methods. The authors of the first five papers to be submitted and accepted at the collection will take advantage of free publication.

Finally, he thanked the hosts of the Bulgarian Academy of Sciences Headquarters: Stefania Kamenova and Assoc. Prof. Dr. Georgi Bonchev, who are also Vice-Chair and Chair of the Executive Board at BgBOL, respectively. A special thanks went also to Prof. Pavel Stoev, Director of the National Museum of Natural History.
