Using DNA to save Nature: Europe’s Next Biodiversity Frontier 

A landmark alliance of DNA experts across Europe signals the start of an unprecedented effort to build a continent-wide system that applies genomics for protecting European biodiversity.

That Europe’s biodiversity faces unprecedented challenges is nothing new: species are vanishing, ecosystems are degrading, and the policy-makers crafting the policies to address these challenges depend on data that is, at times, scarce. 

What is probably less known is that biodiversity genomics – the one that focuses not on humans, but on other living organisms, like animals and plants – is living a revolution that may well provide just the right knowledge that policy-makers need. Never before has DNA-based science been able to identify species, monitor ecosystems, and understand genetic diversity as cheaply, efficiently, and at scale as it can now.

The European Reference Genome Atlas (ERGA), the International Barcode of Life Europe (iBOL Europe), and the Consortium of European Taxonomic Facilities (CETAF) have signed a historic agreement for biodiversity genomics in Europe. These three large scientific communities have committed to building a coordinated European infrastructure for biodiversity genomics: one that will allow experts to work in a connected system of shared resources, technology, and data. 

The vision has taken shape through the Biodiversity Genomics Europe plus (BGE+) project, and aligns with the environmental goals of the European Commission, which has welcomed steps in this direction. In fact, Costas Kadis, EU Commissioner for fisheries and oceans, recently weighed in on the need for common protocols and comparable data, and pointed to the possibility of achieving this goal through an improved and dedicated biodiversity genomics infrastructure for Europe.

We are entering a new phase. Europe already has extraordinary expertise in taxonomy, genomics, bioinformatics, biodiversity collections, and environmental monitoring. The challenge now is bringing these strengths together in a way that allows us to work at scale in an interconnected system, beyond geographic and political limitations.

The initiative emphasises one of the biggest challenges for efficient biodiversity research today: scale. Although more than two million species have been formally described worldwide, scientists estimate that millions more remain unknown, and we all know what this means: we cannot protect what we do not know. But understanding and monitoring biodiversity at the speed required by today’s environmental challenges demands new approaches that boost scientific collaboration and interoperability. Initiatives like BGE+ show the way ahead.

In the words of Gabriela Dankova, BGE+ project manager:

Tackling current biodiversity challenges requires effective collaboration of our communities across Europe, open knowledge exchange, solid technical infrastructure, harmonised processes, and, above all, a shared vision. BGE+ brings these elements together, enabling and amplifying the work of biodiversity genomics communities in Europe and beyond.

Scientists know that discovering and documenting all species is only part of the work. They also need to understand how species adapt to environmental change. That is the reason why BGE+ brings together two different strands of genomics. DNA barcoding allows scientists to identify species quickly and accurately. Genome sequencing provides deeper insights into adaptation, evolution, and resilience. Combined with taxonomic expertise and advanced data systems, these tools are creating entirely new possibilities for understanding and protecting nature.

BGE+’s long-term ambition is to establish the services, standards, capacity, and infrastructure needed for biodiversity genomics to become a routine part of how Europe studies, monitors, manages, and restores nature. The stakes could not be higher.

Pensoft’s role in Biodiversity Genomics Europe plus (BGE+)

Within BGE+, Pensoft plays a leading role in knowledge sharing, skills development, and open publishing in biodiversity genomics. Working with research communities across Europe, the company will identify training needs, develop practical learning resources, and support capacity building for BGE+ cascade projects. At the same time, Pensoft will develop publishing workflows that make biodiversity genomics research easier to publish, discover, and reuse, integrating scientific articles with datasets and metadata via the ARPHA Writing Tool to support FAIR principles and ensure research outputs are more transparent, searchable, and interoperable.

Beyond training and publishing, Pensoft will help translate genomic research into policy-relevant evidence by supporting harmonised standards, open data practices, and clearer communication between researchers and decision-makers. The company will also support iBOL Europe’s community engagement and capacity building through training activities, strengthening collaboration between national and European networks, developing distributed DNA barcoding facilities, and promoting the growth of a comprehensive European DNA barcode reference library.

Curious isolation: new butterfly species discovered

Due to its specific ecological associations and low genetic diversity, this butterfly may soon face challenges with climate change adaptation.

In the heart of Canada’s Rocky Mountains, an unassuming yet remarkable butterfly has been quietly flying under our scientific radar for years. With a wingspan of an inch to an inch and a half, and wings that are brown on top and greyish brown with black spots below, this population was long thought to belong to the Half-moon Hairstreak (Satyrium semiluna). However, the isolated hairstreak butterflies of Blakiston Fan in Waterton Lakes National Park, Alberta, have now been recognized as a distinct species: Satyrium curiosolus, or the Curiously Isolated Hairstreak.

A recent study by an international collaborative team, published in ZooKeys, uncovered the unique evolutionary history of this population. The results were striking: Satyrium curiosolus has been completely isolated from its closest relatives for quite a while—possibly up to 40,000 years— becoming more and more genetically and ecologically unique along the way.

The science behind the discovery

“Our whole-genome sequencing of S. curiosolus revealed strikingly low genetic diversity and exceptionally high levels of historical inbreeding compared to the geographically nearest S. semiluna populations in British Columbia and Montana, more than 400 km distant,” says co-first author Zac MacDonald, a La Kretz postdoctoral researcher at University of California Los Angeles Institute of the Environment and Sustainability. Despite its small population size, genetic data suggest that S. curiosolus has likely maintained itself as a stable, independent lineage for tens of thousands of years. “Like the Channel Island Fox, S. curiosolus may have purged some of its harmful recessive genetic variation through a long, gradual history of inbreeding, allowing it to persist as a small and completely isolated population today,” MacDonald adds.

Satyrium curiosolus is found in a distinct habitat unlike any other population of S. semiluna that we know of. While its relatives thrive in sagebrush steppe, S. curiosolus occupies a single alluvial fan that is more accurately described as prairie-grassland, where it associates with different plants and ant species. Satyrium curiosolus relies exclusively on silvery lupine (Lupinus argenteus) for larval development, a plant not known to be used by S. semiluna populations in British Columbia.

“Furthermore, we recently discovered that S. curiosolus larvae have mutualistic relationships with a particular species of ant (Lasius ponderosae), which has not been observed in other S. semiluna populations,” says James Glasier of the Wilder Institute/Calgary Zoo, who was also part of the study. Satyrium curiosolus caterpillars provide the Lasius ants with a sugary excretion called honeydew to eat, while in return the ants protect the caterpillar from parasites and predators. Caterpillars also retreat into ant galleries when disturbed, or when it gets too hot out, and adult females have been observed laying eggs right near the entrances to Lasius colonies under Silvery Lupines.

Why it matters

The recognition of S. curiosolus as a species has important implications, highlighting its unique evolutionary trajectory and emphasizing an urgent need for tailored conservation strategies.

The discovery of S. curiosolus is a powerful demonstration of how genomics is revolutionizing taxonomy and conservation.

Satyrium curiosolus faces a somewhat unique challenge: its long-term isolation has resulted in very low genetic diversity, which means that the species has a reduced potential to adapt to changing climatic conditions. While conservationists often consider genetic rescue—introducing individuals from related populations to boost genetic diversity—as a solution to low genetic diversity, the distinctiveness of S. curiosolus raises concerns about potential outbreeding depression when mixed with S. semiluna. It is likely that the two species are not even reproductively compatible, meaning S. curiosolus may be on its own. Conservation efforts must now consider new solutions, such as establishing additional S. curiosolus populations, to help this butterfly persist as climate change threatens ecological change at Blakiston Fan.

“The discovery of S. curiosolus is a powerful demonstration of how genomics is revolutionizing taxonomy and conservation,” remarked co-first author Julian Dupuis, an Assistant Professor in the Department of Entomology at University of Kentucky. “While traditional taxonomic methods often rely on morphology alone, our study underscores the importance of integrating genomic and ecological data to uncover hidden diversity. With the rise of genomic tools, previously unrecognized species like S. curiosolus are being discovered, highlighting the need for conservation strategies that account for cryptic biodiversity.” Dupuis adds.

Collaboration in conservation

The Curiously Isolated Hairstreak reminds us that even the smallest and most overlooked species can hold extraordinary scientific and conservation significance.

“Our studies on S. curiosolus and S. semiluna highlight the importance of collaboration between academic scientists, nonprofit organizations, and conservation managers. All of this work was made possible through partnerships between academic researchers, Parks Canada, and the Wilder Institute/Calgary Zoo. By combining expertise in genomics, field ecology, and conservation management, we were able to produce findings that not only reshape our understanding of biodiversity but also provide actionable insights for species protection. Moving forward, these interdisciplinary collaborations will be critical for tackling complex conservation challenges and ensuring the long-term survival of species like S. curiosolus,” added MacDonald.

The future of Satyrium curiosolus

Recognizing S. curiosolus as a distinct species is just the beginning, the researchers say. Future research should explore its evolution and interactions with other species like host plants and ants. Additionally, long-term monitoring by Parks Canada and the Wilder Institute/Calgary Zoo will be essential to assess how this species copes with climate change and what conservation actions are appropriate. “This is a wonderful example of how such monitoring can connect diverse approaches and impactful answers to a simple question like ‘that’s odd – why is it there?’”, says anchor author Felix Sperling, a professor at the University of Alberta and curator of the U of A’s Strickland Museum of Entomology.

“For now, the Curiously Isolated Hairstreak reminds us that even the smallest and most overlooked species can hold extraordinary scientific and conservation significance,” the researchers say in conclusion.
