Grassland butterflies: important indicators of the state of nature

With the Grassland Butterfly Index for Germany, UFZ scientists are providing important input for the implementation of the EU Nature Restoration Regulation.

One of the goals of the EU Nature Restoration Regulation, which came into force in 2024, is to halt species loss and preserve important ecosystem services provided by agricultural landscapes.

Scientists at the Helmholtz Centre for Environmental Research (UFZ), in collaboration with the Senckenberg German Entomological Institute (SDEI), have now calculated the Grassland Butterfly Index for Germany – an indicator of the state of biodiversity proposed in the EU regulation.

The results, published in the open-access journal Nature Conservation, show a negative trend, especially in recent years. For their calculations, the researchers were able to draw on 4 million observation data collected at the UFZ over the last 20 years as part of the ‘Butterfly Monitoring Germany’ programme.

Agricultural landscapes are among the most degraded habitats worldwide. Their restoration is one of the key measures for halting global biodiversity loss and preserving important ecosystem services.

“The Nature Restoration Regulation (NRR), which came into force in 2024, is an essential instrument for achieving the restoration targets set for the European Union,” says Prof. Josef Settele, agroecologist at the UFZ. The objectives also include increasing biodiversity in agricultural ecosystems (Article 11 of the NRR), taking into account climate change, the needs of rural areas and sustainable agricultural production. To implement the overall objectives, EU Member States are required to develop national restoration plans and implement concrete measures in terrestrial, freshwater, coastal and marine habitats.

The extent to which the specific measures are effective and the ecosystems develop positively will be determined using indicators. For agricultural landscapes, these are (a) the grassland butterfly index, (b) the stock of organic carbon in cropland mineral soils, and (c) the share of agricultural land with high diversity landscape features. For at least two of these three indicators, the EU regulation calls for an upward trend towards a satisfactory level by 2030. Since natural conditions vary across EU countries and there is a wide range of different land management practices, Josef Settele argues that all EU countries should start by recording all three indicators so that none of them is prematurely dropped.

With the ‘Grassland Butterfly Index’, a research team led by the UFZ has now calculated one of the three indicators for Germany for the first time and published the results in the journal Nature Conservation. The data for this analysis comes from Butterfly Monitoring Germany (Tagfalter-Monitoring Deutschland – TMD), a long-term programme coordinated by the UFZ and the Society for Butterfly Conservation (GfS). Every week during the summer, volunteers count butterflies at fixed locations using a standardised European method.

“Since the TMD was launched in 2005, this has resulted in around four million data records being collected, which provide information on the development of butterfly populations in Germany,” explains one of the co-authors of the publication, biologist Elisabeth Kühn, who coordinates the German Butterfly Monitoring programme at the UFZ.

What does the index show for Germany?

The ‘Grassland Butterfly Index’ tracks the development of populations of 15 butterfly species from 2006 to 2023 that are considered typical inhabitants of various grassland biotopes.

Of the 15 indicator species, four are increasing (green), five are declining (red) and no significant trend could be identified for six species (grey). ©UFZ.

“Four species have increased, five species show a declining trend. For six species, the trend is uncertain, which is probably due to insufficient data and large differences between the locations where they were found,” says the study’s lead author, bioinformatician Alexander Harpke. In the first decade of the period analysed (2006 to 2016), the index for Germany as a whole shows a slightly positive trend – which does not rule out the possibility that this may vary greatly for individual species.

However, if we look only at recent years (2016 to 2023), the index shows a significant decline overall. This mainly affects specialised species such as the Small Blue (Cupido minimus) or the Dingy Skipper (Erynnis tages); generalists such as the Small Copper (Lycaena phlaeas) or the Meadow Brown (Maniola jurtina) are hardly affected.

These results show that the trend for grassland butterflies in Germany during the comparison period corresponds to the trend at European level, which was last determined by Butterfly Conservation Europe in 2025 for all 27 member states.

Butterflies as indicators

Butterflies are known to be sensitive to changes in their environment. Land use plays a decisive role in this. “The loss and fragmentation of habitats have a proven negative effect on the long-term survival of butterfly populations. Intensive mowing, nitrogen inputs and pesticides contribute to a deterioration in habitat quality or increased mortality. Species that depend on specific habitats, such as nutrient-poor grasslands, also suffer from a lack of use, e.g. through grazing or mowing,” explains Prof. Thomas Schmitt from the Senckenberg German Entomological Institute (SDEI) in Müncheberg, who is also co-author of the study.

In addition to land use, climate change is increasingly contributing to changes in butterfly fauna. Higher temperatures favour the spread of heat-loving or tolerant species, while species adapted to cooler conditions are in decline.

These dependencies of butterflies on land use and climate change make them excellent indicators of the state of our ecosystems. In addition, they are easy to record – especially by qualified volunteers. Together, these two factors have provided an invaluable database for butterfly monitoring in Germany, which scientists are now evaluating to calculate trends and indicators for reporting under European environmental legislation.

“The significance and representativeness of the indicator could be further increased if government programmes such as Habitats Directive monitoring or nationwide insect monitoring were integrated into the analysis,” says UFZ biologist and co-author of the publication Dr Martin Musche. The same would apply if data from neighbouring countries were included.

The work on this publication was funded by the UFZ and the GfS, as well as by the National Monitoring Centre for Biodiversity and the Federal Agency for Nature Conservation (BfN) as part of the FAMos project, with funds from the Federal Ministry for the Environment, Climate Protection, Nature Conservation and Nuclear Safety (BMUKN).

Hornet invaders: British public urged to report yellow-legged bee killers

Originating from Asia, invasive yellow-legged hornets have spread across western Europe, threatening bee populations.

Researchers have emphasised the vital role of public reporting in controlling the invasive yellow-legged hornet (also known as the Asian hornet) in Great Britain.

Indigenous to Southeast Asia, the hornet (scientific name: Vespa velutina nigrithorax) was first detected in France in 2004 and has since rapidly spread across western Europe, including Great Britain.

Tracking an invasion – a single Asian hornet sparked the ongoing spread across Europe

This species poses a serious danger to native pollinators, especially honeybees (Apis mellifera), which lack natural defenses against the hornet’s predation. The hornet’s arrival threatens both biodiversity and the beekeeping industry, with intense predation leading to depleted colony reserves and deaths.

A new research paper published in the open-access journal NeoBiota presents a simulation model that predicts the hornet’s dispersal and gauges how long official nest-detection efforts could remain effective before being overwhelmed. The model considers natural dispersal, genetic factors such as the production of diploid (and therefore infertile) males and the realistic distribution of public observers in the landscape.

Without public reporting, the study found that hornet populations in Britain could become unmanageable within 3–7 years of undetected spread, overwhelming resources for nest detection and destruction. However, when public and beekeeper reports are incorporated, control efforts can remain effective for at least 10 years, with this window extending based on reporting rates and observer density.

Three maps of Great Britain showing a decreasing density of hornet sightings correlating with increasing public reports.
Mean density of undetected nests (per km2), estimated at year six for scenarios involving two incursions per year. A) Average density in scenarios where control is absent B) Under the lowest national reporting probability C) Under the highest national reporting probability. Each scenario was estimated across all 100 simulations.

Proximity to populated areas greatly increases the likelihood of successful nest discovery and destruction as they are much better protected due to frequent sightings and reports. Conversely, nests in remote or sparsely populated zones pose a greater risk of escaping detection and fueling further invasion.

Public awareness campaigns, online reporting tools, and targeted outreach to beekeepers have proved highly effective. For instance, in 2023, nearly 21,000 public reports led to 72 nests being destroyed. Now researchers call for continued improvement of such engagement strategies, especially in vulnerable low-density regions.

New agamid lizard described from China

At 6–7 cm long with a wheat-coloured tongue and distinct markings, it’s the 47th Diploderma species recorded in China.

Researchers from China just described a new species of mountain lizard from the upper Dadu River Valley in the Hengduan mountains of Sichuan Province.

Since 2018, the research team conducted numerous surveys in the upper reaches of the Dadu River. There, they encountered a lizard species that showed unique characteristics not previously observed among known Diploderma species in the region. Through molecular biological analyses and morphological studies, they confirmed that this was indeed a previously unrecognized species and gave it the name Diploderma bifluviale, referencing the location where it was found: the confluence of two rivers, Chuosijia and Jiaomuzu.

Diploderma bifluviale is the 47th species of Diplodermain China. The genus Diplodermais distributed across East Asia and the northern part of the Indochinese Peninsula.

With a length of 6-7 cm, D. bifluviale has many distinctive features, such as its wheat-coloured tongue and unique coloration. Unlike its closest relatives, it lives in semi-arid shrublands in warm-dry valleys at elevations of 2,100 to 2,500 m, residing in arid shrublands with small leaves and scattered rock piles.

A camouflaged lizard rests on a rocky, sandy surface.

“This discovery highlights the understudied biodiversity of the upper Dadu River,” the researchers say in their paper, which was published in the open-access journal ZooKeys.

Scientists call for a global alliance to place biodiversity at the heart of the UN Pact for the Future

A new white paper delivers a clear message: protecting biodiversity is not just an environmental issue. It is essential for food security, public health, climate stability, and the global economy.

A new white paper: “From Knowledge to Solutions: Science, Technology and Innovation in Support of the UN SDGs”, published in the open-science scholarly journal Research Ideas and Outcomes (RIO), brings together leading voices from Europe’s biodiversity and data science communities to deliver a clear message: protecting biodiversity is not just an environmental issue. It is essential for food security, public health, climate stability, and the global economy. 

The authors make a call for a decisive shift: from fragmented initiatives to a holistic, global approach to biodiversity research and policy, already demonstrated during a workshop at the 79th United Nations General Assembly and the Science Summit (UNGA79). A key part of this transformation concerns the role of research infrastructures in connecting science, technology, and policy: from vast biodiversity collections and genomic observatories, to ecosystem “digital twins” powered by supercomputers.

Behind the paper are a network of legal entities based in Europe and holding global interests, which includes biodiversity, ecology, and engineering communities, coordinated by the LifeWatch European Research Infrastructure Consortium (ERIC). 

With their combined expertise and through European initiatives, such as Research Infrastructures, e-Infrastructures, the European Open Science Cloud (EOSC), the Digital Twin projects and academic publishers, these communities provide a basis for collaboration in strategically contributing to the implementation of the Kunming-Montreal Global Biodiversity Framework (K-M GBF) targets.

Biodiversity needs to be placed at the centre of the upcoming 2026 UN Summit of the Future and become a core pillar of the agenda after the 2030 deadline for the United Nations Sustainable Development Goals (UN SDGs).

The UN Pact for the Future should include biodiversity as a core pillar: “not only of environmental sustainability, but of equity, security, and intergenerational justice”.  

urges the team.

To do this, the authors propose the establishment of a global alliance that will strategically integrate biodiversity conservation into the core priorities of the UN Summit of the Future and the post-SDG agenda.

This alliance is meant to join the voices of researchers, policymakers, indigenous knowledge holders, civil society, and industry to ensure that biodiversity underpins peace, prosperity, and justice as a universal enabler.

The white paper also demonstrates how the research infrastructures collectively contribute to the seven Strategic Considerations of the K-M GBF, outlined here in brief and further detailed in the full publication:

  1. Contribution and rights of Indigenous Peoples and local communities: Ensuring fair recognition and sharing of benefits with indigenous peoples and local communities, thus integrating their knowledge into biodiversity science.
  2. Collective efforts towards the targets of the K-M GBF: Coordinating biodiversity monitoring, databases, and digital infrastructures to track progress towards global conservation targets.
  3. Fulfilment of the three principal objectives of the Convention on Biological Diversity (CBD) and its protocols: Studying or supporting the study of all aspects of biodiversity; and providing public and streamlined access to biodiversity information.
  4. Implementation through science, technology, and innovation: Developing and offering technologically advanced and novel solutions for research, data sharing and management to various users; and promoting open science by publishing research findings and increasingly sharing more facets of the research process.
  5. Ecosystem approach: Developing and implementing technologies that enable a cross-domain, multidisciplinary approach to studying biodiversity and ecosystems; and using holistic, cross-disciplinary methods to understand and predict biodiversity and environmental dynamics.
  6. Cooperation synergies: Collaborating with organisations responsible for implementing the CBD, policy agents, international research projects; and participating in international forums and social, scientific and technical initiatives.
  7. Biodiversity and health linkages: Demonstrating how healthy ecosystems support human health, food security, and resilience to pandemics by supporting interdisciplinary research through bringing together knowledge and data and uncovering links and interactions between humans and the environment.

“With the UN’s ‘Pact for the Future’ currently being shaped, we see a unique opportunity to anchor biodiversity as a unifying thread across global goals that will transform how societies respond to the intertwined crises of climate change, nature loss, and pollution,” say the authors.

The white paper is the latest contribution to the LifeWatch ERIC Strategic Working Plan Outcomes open-science collection meant to provide a one-stop access point to the most important deliverables by the European biodiversity and ecosystem research infrastructure, which is currently undergoing a significant upgrade as a response to the needs of its target communities and stakeholders.

The bee’s knees: a new, non-lethal way to study pollinator networks

Guest blog post by Alexander Edwards, lead author of the paper ‘Case study of non-lethal sampling for plant-pollinator networks via barcoding and metabarcoding on bumble bees in Germany‘ published in Metabarcoding and Metagenomics.

“Who are you and what have you done?”

That’s not just a question for crime shows. It’s also exactly what we want to ask every pollinating insect we catch. Who are you – which species? And what have you done – which flowers have you visited, carrying pollen from one to the next? And these questions are important!

Do you like chocolate? Or maybe coffee? How about apples, strawberries, or cherries? All of them need insect pollinators. Unfortunately, many insects are in decline, threatening the stability of ecosystems. Studying them is more important than ever. Traditionally, researchers relied on field observations of foraging behaviour. But these are time-consuming and can never capture the full picture. That’s why many groups now use genetic approaches, studying the pollen carried by insects. This method is called pollen-metabarcoding, where a short genetic sequence from a specific region (in our case, ITS2) can identify the plant species that pollen belongs to.

There’s just one catch: collecting pollen often means killing the insect. Lethal sampling does have its merits – the preserved specimen can be used to answer other questions in the future, for example. But in our case, it felt counterintuitive. We want to study species that might already be endangered, and killing them could worsen their situation. So we had to find another way.

the genetic material we need for our analyses. Credit: Willi Müller.

Enter: the queen-marker cage. This tool – borrowed from beekeepers – is a plastic tube with a mesh at one end and a plunger at the other. We used it to capture a bumble bee, immobilize it, and remove its pollen. The mesh is also large enough to clip one of the bee’s feet – in insects, this part is called the tarsus. That may sound harsh, but it doesn’t significantly affect the animal. During our collection, we observed those five-footed bumble bees visiting flowers and gathering pollen in the days after release, with no difference to their six-footed counterparts.

The mesh of the queen-marker cage is just big enough for a fine pair of scissors
to fit through the holes and allow for precise clipping of the bumble bee’s tarsus, here
Bombus lucorum agg.

But why take a bee’s foot in the first place? Many animal groups include cryptic species – species that look almost identical, even to experts. Bumble bees are no exception. The only reliable way to tell these look-alike species apart is through DNA barcoding, often using the COI gene. A single clipped foot provides just enough tissue to barcode the bee itself, in addition to analyzing the pollen it carried.

Of course, the work doesn’t end in the field. Once we had the samples, the real detective work started in the lab. And as everyone with hay fever knows: pollen gets everywhere. To avoid contamination, we processed everything in a special clean lab, wearing full-body protective suits. It may seem over the top, but when you’re working with invisible grains of pollen, even the smallest contamination can skew the results.

As pollen is everywhere, we had to use a special clean lab with the
corresponding attire.

And in the end, it worked! Our results matched expectations: we detected a cryptic species (fittingly named Bombus cryptarum), we saw that the longest flowers were visited only by bumble bees with the longest tongues, and the pollen we identified came from plants flowering at our study sites during collection.

Now we have a simple and non-lethal way to gather the genetic material needed to identify pollinators and the flowers they visit, answering ‘Who are you, and what have you done?’ – without adding pressure to vulnerable insect populations.

Pensoft to co-host a session on knowledge transfer & continuity at Living Data 2025

Pensoft is a co-organiser of a four-hour session, titled: “Long Live Biodiversity Data: Knowledge Transfer and Continuity across Research Projects”. 

In October 2025, four major institutions in the biodiversity research landscape: TDWG, GBIF, OBIS and GEO BON, will come together as the organisers of the Living Data 2025 conference. 

The event is set to be among one of the most crucial international gatherings of the year for experts and stakeholders in the field of biodiversity data. Set to take place in the Colombian capital of Bogotá between 21st and 24th, Living Data 2025 will centre around four core themes:

  • Open data
  • Data integration
  • Biodiversity data application
  • Community engagement and capacity-building

As an academic publisher with experience and commitment to all these thematic areas, Pensoft will participate in the event in the capacity of an exhibitor and an award sponsor, as well as a symposium host. 

The conference delegates will have the chance to learn more about the publisher, its exclusively open-access scholarly portfolio and participation at various international scientific projects when they visit the company’s branded stand. 

During the event, the scientific publisher and technology provider will also present the Pensoft Award for the Best Student Oral Presentation, which grants the winner a free publication in an open-access, peer-reviewed journal from our portfolio. 

Crucially, Pensoft’s involvement in the Living Data 2025 programme also includes a dedicated four-hour session titled “Long Live Biodiversity Data: Knowledge Transfer and Continuity across Research Projects”. 

The symposium will be jointly co-organised by Pensoft, LifeWatch ERIC and the Naturalis Biodiversity Centre. As the title suggests, the session will focus on the longevity of scientific outputs as they are generated, shared and re-used across disciplines, organisations and initiatives. In this context, tools, information hubs and workflows enabling exchanges that truly consolidate the global biodiversity data space over time will be showcased.

In a broader sense, the session will also seek to demonstrate how targeted communication can help transform science results into actionable knowledge by raising awareness among agenda-setters. This will speak to the potential of a multi-level approach to information sharing to bridge the gap between science and policy in relation to increasingly ambitious global environmental objectives.

Multiple projects affiliated with Pensoft will be represented in these deliberations, in order to share a diverse array of relevant insights:

The symposium will be divided into two sessions:

  • 22 October (Wednesday): 10:45 AM – 12:45 PM (UTC/GMT-5)
  • 23 October (Thursday): 10:45 AM to 12:45 PM (UTC/GMT-5)

You can find out more about Living Data, including the details on registering for an in-person or virtual attendance, on the conference’s website. Our session is listed on this page under ID number 6788879.

As an additional note, the organisers of the conference have launched a call for extended abstracts for all speakers at Living Data 2025 that will remain open until 1st October 2025. The participants who opt to publish their conference abstracts in the Biodiversity Information Science and Standards (BISS) journal will enjoy permanent and far-reaching accessibility and discoverability for their conference contributions.

The TDWG network, who launched BISS as their official scholarly outlet in 2017 in collaboration with long-time partner Pensoft, have posted a list of the advantages for submitting an extended abstract, even though they have already had their abstracts accepted by the Living Data 2025 organisers. Amongst the reaslons are many perks typically associated with a conventional research article, such as DOI registration, indexation at dozens of scientific databases, embedded media, tables and supplementary materials, and usage metrics.

Til moth do us part: new species marks 42 years of marriage

“It is without a doubt the prettiest species I have encountered in my long scientific career,” said Huemer, who named the moth after his wife.

European Lepidoptera (butterflies and moths) are generally considered well-known and thoroughly researched. Nevertheless, researchers discover new species every year; most of which are inconspicuous, so-called ‘cryptic’ species, previously overlooked.

Colourful species, on the other hand, have been largely catalogued in Europe as they attract a lot of attention, which made the surprise and delight at the discovery of an extraordinarily striking, and previously unnamed, moth all the greater.

A newly discovered, pink species has now been named Carcina ingridmariae by Peter Huemer, a scientist at the Tyrolean State Museum Ferdinanduem (Innsbruck, Austria). Huemer published his discovery in the open-access journal Alpine Entomology.

According to current knowledge, the moth is widespread in the eastern Mediterranean region: distributed from Croatia across large parts of Greece and Cyprus to Turkey. However, more detailed studies on its distribution are still pending.

Seemingly unmistakable

Ingrid-Maria’s carcina belongs to a species-poor group of butterflies. In Europe, there is only one other species of the same genus, the oak carcina (Carcina quercana).

This widespread moth was described as early as 1775 by the famous naturalist Johann Christian Fabricius based on specimens from Saxony, and is distributed from North Africa across large parts of Europe to the Balkans.

Due to its unusual colour, the species has always been considered unmistakable. In fact, it is so popular even among amateur researchers that it adorns the cover of an important British identification book.

But, hiding in plain sight, was a second species, mistaken for the oak carcina for more than 100 years.

As a result of its apparent unmistakability, Carcina ingridmariae was always misidentified and was first published – incorrectly – as the oak wood carcina from Crete in 1916.

It was only the introduction of new molecular identification methods that put researchers at the Ferdinandeum on the trail of the nameless moth. DNA barcodes, also known as genetic fingerprints, showed huge differences of more than 6% between the two species.

Subsequent morphological examination of the sexual organs led to the famous “wow” effect. And, upon closer inspection, the two species could not be confused at all, despite the confusingly similar external appearance of the species: namely, a wingspan of about 2 centimeters, a pink base colour with yellow spots, and strikingly long antennae.

A special gift for a 42nd wedding anniversary

Peter Huemer has described more than 200 species from Europe in 35 years, but is particularly enthusiastic about this new species. He said: “It is without doubt the prettiest species I have encountered in my long scientific career, even though it was still unnamed.”

It was therefore obvious to Huemer that he should dedicate the new species to his wife, Ingrid Maria, on their 42nd wedding anniversary. The researcher justifies this choice of name above all with his wife’s decades of support for his work.

Hidden in sacred forests: A newly described microendemic gecko from Madagascar

Reserves managed by local communities are essential for the survival of species like P. tsaranoro.

A team of international herpetologists has described a new gecko species that has managed to hide in plain sight among the granite boulders around the western flanks of the Andringitra Massif, in south-eastern Madagascar. “Paragehyra tsaranoro is named after the Tsaranoro valley, where it was first observed,” explains first author Francesco Belluardo from the Department of Bioscience and Territory at the University of Molise (Italy). “It is not only endemic to Madagascar, but also what we describe as a microendemic species—restricted to an extremely small range.”

A close-up photo of a gecko against a blurred natural background.

In this case, P. tsaranoro has only been found in three small forest fragments, all located within approximately 15 kilometers of one another. These patches are remnants of a once-larger and continuous forest that has been destroyed by the widespread deforestation that continues to impact Madagascar’s biodiversity.

“The findings emphasise the importance of conducting research on small forest fragments, as they are essential for completing the inventory of Malagasy herpetofauna,” the researchers write in their study, which was published in the journal ZooKeys.

Given its very limited range and the ongoing threats to its habitat, the authors recommend listing this new gecko as Critically Endangered on the IUCN Red List. Like many endemic species in Madagascar, its existence might be threatened by deforestation, which means destruction and fragmentation of its already limited habitat. The research team, composed also of Angelica Crottini, Javier Lobón-Rovira, Gonçalo M. Rosa, Franco Andreone, Malalatiana Rasoazanany, Costanza Piccoli and Ivo Oliveira Alves call for stronger support for local communities in conserving the species. In fact, most of its known range lies outside Madagascar’s network of protected areas, and the only conservation measures come from reserves managed by local communities—areas created to support sustainable livelihoods and protect local biodiversity.

“Building on previous research in the region, it appears that this landscape is full of hidden biodiversity gems, including other microendemic reptile species found nowhere else in the country. These community-managed reserves act as important refuges for local wildlife,” says Belluardo. “Interestingly, many of these small forest fragments are known locally as ‘Forêts sacrées’, or sacred forests, because they host boulders that serve as ancestral tombs for the local Betsileo people. Protecting this cultural heritage has also helped safeguard local species, suggesting once again that conserving biodiversity often goes hand-in-hand with preserving cultural traditions.”

Manga mollusc: new deep-sea species named after ONE PIECE character

Found 6 km beneath the Pacific, the limpet’s unusually large size inspired its name.

Whether its naming a spider after Venom (and Tom Hardy), a crab after a League of Legends raccoon-thing, or a giant isopod after Darth Vader, researchers have a long history of honouring their favourite pop-culture characters when naming new species.

So, when researchers from the Japan Agency for Marine-Earth Science and Technology (JAMSTEC) discovered a new limpet species deep below the northwestern Pacific Ocean, it should come as no surprise that they looked to a nautical manga series for inspiration.

Published as a new species in the open-access journal Zoosystematics and Evolution (follow the journal on Bluesky here), the deep-sea limpet was found on hard volcanic rock 500 kilometres southeast of Tokyo at a depth of almost 6 km, the deepest known habitat for any true limpet (subclass Patellogastropoda).

The gastropod measures up to 40.5 mm in shell length, which is a remarkably large size for a true limpet from such depths and another source of inspiration for the species’ name.

So, what is that name?

The research team named the new species Bathylepeta wadatsumi, which is both a reference to Wadatsumi, the god of the sea in Japanese mythology, and the character “Large Monk” Wadatsumi, from the manga series ONE PIECE.

In ONE PIECE,”Large Monk” Wadatsumi is a giant fish-man and a member of the Sun Pirates. To avoid spoilers, that’s all we will say about the character, but as far as the reference goes: Wadatsumi is big, the limpet is big, and the authors love ONE PIECE.

So much so, that they paid further homage to the world’s most popular manga series in the acknowledgements section of their paper, writing:

“We also take this opportunity to salute Eiichiro Oda for continuing to chart the epic voyage of ONE PIECE (1997–), which reminds us that the greatest voyages are driven by freedom, camaraderie, and an insatiable thirst for discovery.”

Their own discovery was made possible by access to sophisticated submersible technology.

The new species was collected using the crewed submersible DSV Shinkai 6500, making it the first time a member of the genus Bathylepeta has been observed and photographed live on its natural rocky substrate, rather than being dredged using a net. The use of submersibles is instrumental in accessing these habitats, allowing for direct observation and collection of previously overlooked organisms.

“Even in an age of sophisticated remotely operated vehicles, there’s often an edge to the human eye on the seafloor. Crewed submersibles like Shinkai 6500 let us explore with intention and nuance—spotting lifeforms like Bathylepeta wadatsumi that might otherwise be missed entirely.”

Dr Chong Chen, lead author.

Beyond its taxonomic significance, the study has broader ecological implications as B. wadatsumi appears to graze on sediment layers over rock, indicating a specialised role in processing organic matter in deep-sea ecosystems.

The findings underscore the need for more comprehensive explorations of rocky abyssal habitats using submersibles to reveal the true diversity and distribution of Bathylepeta and other animals relying on such habitats.

While it remains to be seen whether Luffy and co. will ever find the “One Piece,” we can be sure that their adventures will continue to inspire researchers in their own journies of discovery.

In June, Pensoft joined the 2025 largest meeting for conservation experts

We attended the International Congress for Conservation Biology to present the REST-COAST and SELINA Horizon-funded projects, as well as our scholarly journals and books portfolio.

Over 1,200 people from more than 90 countries, including conservation and social science researchers, students, practitioners, government and NGO professionals, policy specialists and leaders from indigenous groups attended the 32nd International Congress for Conservation Biology (ICCB 2025), hosted by the SCB Oceania Region from 15th to 19th June 2025 in Brisbane/Meanjin, Australia.

A special focus seen across the talks and overall rhetoric of the event was on indigenous peoples, culture and knowledge, and how they can be recognised and further engaged in the study and protection of the environment in a sustainable and culturally appropriate manner. Other topics popular during the week included biocultural diversity and wildlife trade and traffic.

Throughout the week, the delegates enjoyed three sets of plenary talks, and got to choose from upwards of ten parallel sessions taking place three times each day. Multiple workshops and business meetings would also take place every day around lunch time. Then, each day of the congress would conclude with a poster session at the Exhibition hall. Additionally, multiple social events scheduled throughout the week – such as a nature documentary movie night, a science comedy night, and a closing reception, held amongst the exhibits of the Queensland Museum Kurilpa – would take care of the attendees’ entertainment after long days of talks and presentations. 

Our team at Pensoft was proud to join this amazing event as one of the 14 exhibitors at ICCB 2025. At our stand, Pensoft’s Head of Journal development and PR: Iva Boyadzhieva would invite delegates to elaborate on their scientific interests and latest research endeavours, as well as wants and needs concerning the publication, communication and outreach of their work.

Then, visitors would leave the Pensoft stand with helpful advice concerning scholarly publishing and multiple recommended titles from the Pensoft open-access journal portfolio fitting the scope of their research. If you have met us at any event in the past couple of years, you would also know that it is next to impossible for a visitor of ours to leave without at least one of our signature stickers featuring captioned scientific illustrations of species studied in papers from across our journals.

At every event in the past two years, Pensoft has been handing out stickers featuring detailed scientific illustrations of species studied in papers published in Pensoft’s scholarly portfolio. This is our ‘thank you’ to the authors who have trusted our journals with their work. 

Many would also become intrigued to know more about the latest activities and results of the two European Union-funded projects that enjoyed prominent visibility at the Pensoft stand, namely: SELINA (an acronym for Science for Evidence-based and Sustainable Decisions about Natural Capital) and REST-COAST (Large scale RESToration of COASTal ecosystems through rivers to sea connectivity). At both projects, our team takes pride in leading work packages dedicated to the communication and dissemination of the projects’ outputs.

Having started in 2022 and set to run until 2027, SELINA comprises 50 partner organisations coordinated by the Leibniz University Hannover. This transdisciplinary project provides smart, cost-effective, and nature-based solutions to historic societal challenges, such as climate change, biodiversity loss, and food security. A main objective is to identify biodiversity, ecosystem condition, and ecosystem service factors that can be successfully integrated into decision-making processes in both the public and private sectors.

Most recently, the consortium launched SELINA’s Communities of Practice initiative to promote collaborative learning and knowledge integration across Europe. This digital platform provides a forum for scientists, policymakers, practitioners, and business representatives to exchange knowledge and further engage with its real-life application. On the Communities of Practice webpage, visitors may explore how SELINA is driving change across Europe.

Meanwhile, the mission of the EU Horizon’s Green Deal-funded REST-COAST is to address today’s challenges to coastal ecosystems caused by a long history of environmental degradation of rivers and coasts. Bringing together 38 European institutions, led by the Catalonia University of Technology UPC-BarcelonaTech (Spain), the project is set to demonstrate to key stakeholders and decision-makers that large-scale restoration of river deltas, estuaries and coastal lagoons is necessary to sustain the delivery of vital ecosystem services.

A prominent output by the REST-COAST project is a policy brief addressing the EU Nature Restoration Regulation, and serving to provide scientifically-informed policy recommendations and targets.

At the Pensoft stand, ICCB2025 participants had the opportunity to browse through nine fact sheets produced within the project. Each provides a neat snapshot of the story of one of the pilot sites selected by REST-COAST as representatives of particularly vulnerable hotspots for the main EU regional seas (Baltic, Black, North Atlantic and the Mediterranean). On display was also a recent policy brief addressing the EU Nature Restoration Regulation. It serves to provide a concise summary of the issues and challenges at hand, in addition to scientifically-backed policy recommendations and targets.

Both the pilot site factsheets and the policy briefs produced by the consortium are made public in the Media Center on the project website. Further project outputs, including research articles, data papers and project reports, are permanently available from the REST-COAST’s open-science project collection in the Research Ideas and Outcomes (RIO) journal.

On the final day, the ICCB 2025 did not disappoint either. The day started with a touching plenary talk by Amy Van Nice of the Wildlife Alliance, where she shared a lot of her own experience as a wildlife rescuer, but also as a human with her own personal battles along the way. Throughout her talk she remained fully transparent about the current situation in wildlife trafficking, which remains, sadly, a crisis yet to be tackled.

The day continued with a full programme of parallel sessions before everyone gathered for the closing session and the closing ceremony, where delegates could look back at the last year in conservation, and learn about what is to come. The closing ceremony also announced and celebrated the SCB 2025 Global Service Awards and the ICCB awards.

Following the ICCB tradition, the organisers also waited until the end of the event to announce the location of the next international congress. It will take place in 2027 some 12,000 km (7,500 miles) away from Brisbane: in Mexico, where it will be jointly hosted by the North American (SCBNA) and the Latin America and Caribbean (SCB-LACA) regions of the Society for Conservation Biology.
