A new deep-sea chiton has been officially named by the public and described in the Biodiversity Data Journal. The name is the result of a viral, week-long collaboration between science communicator Ze Frank, Senckenberg, and Pensoft Publishers.
From over 8,000 suggestions submitted via social media, the research team responsible for describing the species selected the name Ferreiraella populi. The specific epithet populiis a Latin singular noun in the genitive case meaning “of the people”. Curiously, the name was independently suggested by 11 different contributors during the naming contest.
From a YouTube video to Taxonomy
It all began when Ze Frank featured the rare deep-sea chiton (genus Ferreiraella) in an episode of his “True Facts” YouTube series.
Equipped with an iron-clad radula (a rasping tongue) and eight protective shell plates, the chiton also hosts a tiny community of worms near its tail that feed on its excrements. Everyone was invited to propose a scientific name and justification; within a week the community responded with over 8,000 name suggestions.
“We were overwhelmed by the response and the massive number of creative name suggestions!” says Prof. Dr. Julia Sigwart, co-chair of SOSA at the Senckenberg Research Institute and Natural History Museum Frankfurt. “The name we chose, Ferreiraella populi, translates to “of the people”.
Other notable suggestions included Ferreiraella stellacadens meaning “Shooting star chiton” – named for its unique aesthete pattern and the fact that it “shot to fame” during the selection process.
Another was Fereiraella ohmu in reference to a chiton-like creature from Studio Ghibli, providing a nod to Japan, where the species was discovered.
A Specialized Resident of the Deep
Originally discovered in 2024 within the Izu-Ogasawara Trench at a depth of 5,500 meters, the new deep-sea chiton Ferreiraella populi belongs to the genus Ferreiraella, a rare and specialized group of mollusks that live exclusively on sunken wood in the deep sea.

The new species represents an addition to a lineage of chitons that has been little researched to date and provides further evidence that deep-sea wood-fall ecosystems host highly specialized and still largely undiscovered communities,
explains Sigwart
Chitons are often described as a cross between a snail and a beetle. However, unlike common mollusks with a single shell, chitons possess eight separate shell plates(valves). This unique anatomy allows them to roll into a protective ball or cling to the irregular surfaces of deep-sea wood-falls.
Found in both warm coastal waters and coral reefs as well as the deep sea, chitons can live at depths of up to 7,000 meters under extreme conditions and in absolute darkness.
How is a scientific name formed?
Ever wonder how a creature goes from “that deep-sea thing” to a formal scientific entry? Every newly discovered species is assigned a scientific name as part of its original taxonomic description.
This follows Carl Linnaeus’s principle of binomial nomenclature and consists of two parts: the genus name (the first part, capitalized and italicised) and the specific epithet (the second part, lowercase and italicised).
The name is assigned by the author(s) of the first description in a scientific publication, adhering to international codes such as the ICZN (zoology) or the ICN (botany). The name must be novel, unique, and latinized. Usually, epithets are often derived from characteristics like color or size, geographic locations, mythology, or personal names used to honor a specific individual.

Ferreiraella populi exemplifies the overwhelming biodiversity of the oceans, the vast majority of which remains unexplored. Many species go extinct before we even know they exist – this is especially true for marine invertebrates,
says Sigwart
“It can often take ten, if not twenty years, for a new species to be studied, scientifically described, named, and published. At SOSA, we have therefore made it our mission to streamline these processes while simultaneously engaging the public with these fascinating creatures. Finding a name for the chiton together on social media is a wonderful opportunity to do just that!” comments Sigwart.
“Ferreiraella populi has now been described and given a scientific name only two years after its discovery. This is crucial for the conservation of marine diversity, especially in light of the threats it faces such as deep-sea mining!” she says.

Prophy’s AI-driven discovery system will provide editors with a broader and more diverse pool of qualified peer reviewers based on automated semantic analysis.
In a new partnership between open-access scholarly publisher Pensoft and the AI-driven reviewer discovery system provider: Prophy, the editorial teams at all journals hosted on the publisher’s ARPHA Platform receive access to a broader and more diverse global pool of researchers.
The integration connects ARPHA’s editorial and peer review workflows with Prophy’s continuously updated database of millions of active, qualified researchers. As a result, editorial teams across more than 90 open-access peer-reviewed journals powered by ARPHA can now opt to enjoy data-driven reviewer recommendations based on structured analysis of researcher expertise and publication history, with matches based on each manuscript’s topic, field, and research focus.
This development responds to a growing challenge in scholarly publishing. As submission volumes rise, the pressure on a relatively small pool of frequently invited reviewers increases, which eventually leads to delays and reviewer fatigue. By expanding the pool of potential experts and improving how they are identified with the help of semantic analysis, the integration supports a more sustainable and balanced approach to peer review.
“By working with Prophy, we’re helping editors discover expertise that might otherwise be overlooked, opening the door to a more inclusive, well-distributed, and resilient peer review ecosystem. This is about using technology not to replace human judgment, but to support it in a smarter and more responsible way.”
Prof. Dr. Lyubomir Penev, founder and CEO of Pensoft and ARPHA.
“We’re excited to work with Pensoft and ARPHA to bring smarter reviewer discovery to their editorial teams. Peer review should be efficient and fair, and this partnership helps with both. Editors can find the right expertise faster, which means less time searching and fewer delays. This integration helps editorial teams manage growing submission volumes without burning out their reviewer networks.”
Oleg Ruchayskiy, CEO of Prophy.
To further support editorial teams and client journals’ owners, Pensoft and ARPHA are offering the Prophy integration free of charge to all journals on the platform until the end of 2026.
The partnership reflects Pensoft and ARPHA’s continued focus on equipping journals with practical, forward-looking tools that strengthen peer review, support editors, and help ensure the long-term sustainability of scholarly publishing.

Scientists compiled and summarized the largest dataset to date on the cladocerans of the Republic of Tyva—the result of almost thirty years of field work.
Guest blog post by Nadezhda Kirova, Valeria Kirova, Alexey Kotov and Dr. Petr Garibian
The functioning of freshwater ecosystems is impossible without cladocerans (water fleas), which play a key role in the food chains of most continental water bodies. Although the cladoceran fauna is relatively well-studied in the Palearctic as a whole, vast territories of Central Asia, including the Republic of Tyva, have until recently been only fragmentarily studied and required systematic survey.

The first mentions of water bodies in Tyva date back to the 16th century, with the first data on zooplankton appearing in the early 20th century in the works of the Norwegian researcher Georg Ossian Sars (1903) and the Soviet scientist Vyacheslav Rylov (1923, 1930). Historical events of the 20th century significantly influenced the development of hydrobiological research in the region: after the republic became part of the USSR in 1944, the study of water bodies was actively conducted within the framework of ichthyological and fisheries tasks.
Starting from the 1960s, under the leadership of Tomsk scientists Alexey Gundrizer and later Victor Popkov, large-scale ichthyological and hydrobiological research was carried out in the region. During this period, zooplankton was studied primarily as a food source.
Cladocerans — the invisible foundation of freshwater life

If you were to scoop up water from any lake, pond, or steppe salt marsh and examine it under a microscope, you would almost certainly see cladocerans among the first creatures—microscopic crustaceans, usually 0.2–6 mm in size, invisible to the naked eye, but playing a huge role in freshwater ecosystems.
What are they?
Cladocerans are small crustaceans with a characteristic rounded or oval body shape; in most species, the limbs are hidden behind paired valves or a carapace. Externally, they may resemble miniature droplets pulsating in the water. The most well-known representatives of cladocerans are from the genus Daphnia. When first discovered, they were called “pulex aquaticus” or “water flea,” a term still used in scientific publications.
What is their role in nature?

Cladocerans play a key role in the functioning of freshwater ecosystems. Primarily, they are a central link in food chains: continuously filtering water and consuming phytoplankton, bacteria, and organic particles, these tiny crustaceans regulate the intensity of algal blooms, maintain water transparency, and control algal numbers. Thanks to cladocerans, many processes in aquatic ecosystems remain balanced, and they themselves serve as a crucial food source for the fry of most freshwater fish and predatory insect larvae. Without them, many species simply could not survive their early stages of development.
Thus, cladocerans perform the function of ecosystem sanitizers. By filtering water, they cleanse it of fine organic debris and bacteria, acting as a natural “microbial vacuum” that maintains freshwater quality.
Finally, these crustaceans are very sensitive to changes in the aquatic environment. Some cladocerans quickly react to changes in salinity, the presence of heavy metals, toxic substances, and other types of pollution. Thanks to this sensitivity, cladocerans are widely used in water quality biotesting, making them a valuable tool for environmental monitoring.
How do they survive?

Cladocerans have an amazing life cycle. Under favorable conditions, they reproduce by parthenogenesis, without the participation of males—females simply clone themselves. This allows them to instantly colonize temporary water bodies after rains or snowmelt.
When “hard times” come—with the onset of cooling, shorter daylight hours, or the drying up of a water body—cladocerans produce resting eggs. These eggs are covered with a strong shell, can withstand drying, frost, and persist in bottom sediments for decades. Sometimes this “cladoceran archive” in the silt is used to study past climatic epochs—like a natural flash drive.
Where do they live?
Almost everywhere, on all continents including Antarctica. They can be found in diverse continental water bodies: rivers, lakes, swamps, ditches, puddles, and other temporary pools. There are even unique species living in leaf axils, tree hollows, damp moss, groundwater, and caves.
The cladocerans of Central Asia are very diverse, where fresh, slightly saline, and saline water bodies are in close proximity—each with its own unique crustaceans.
Why are they important for science?

Cladocerans are an ideal model for ecologists:
They reproduce quickly.
They are easily cultivated.
They instantly react to environmental changes.
They survive climatic changes.
They form the basis of freshwater communities.
Specimens found in permafrost allow scientists to literally “reconstruct zooplankton communities of the past,” comparing populations from different periods, researching evolution in real time, and tracing climate change processes.
Tyva
The Republic of Tyva is one of the most contrasting and unusual regions of Eurasia. Within a relatively small area, almost all of the Earth’s natural zones are found—from semi-deserts and dry steppes to alpine meadows and high-mountain tundras.
Republic of Tyva on the map
The climate in the region is sharply continental, with cold winters, hot summers, large daily temperature fluctuations (up to 30°C), and extremely low precipitation, especially in the steppe basins. The climate in the mountains is milder, with more precipitation, warmer winters, and cooler summers than in the basins. The highest peaks have eternal snow. The highest mountain, Mongun-Taiga, is 3976 meters above sea level. This diversity of natural and climatic conditions creates a wide ecological spectrum.
The landscape mosaic of Tyva is impressive—steppe plains with sand massifs, taiga slopes, high-mountain plateaus, swampy areas, and numerous lakes coexist here. There are about two thousand lakes in Tyva, from large ones like Chagytai and Azas to small brackish and freshwater lakes.
The Ubsunur Basin stands out among the natural landscapes—a unique transboundary natural complex included in the UNESCO World Heritage List. Here, in a small area, one can find desert, steppe, tundra, and alpine meadows, as well as many lakes with varying degrees of mineralization—from almost fresh to hyperhaline.
This combination of contrasting climatic zones, altitudinal gradients, types of water bodies, and salinity levels makes Tuva a natural laboratory for studying aquatic biota.
Dataset
In the course of the research, scientists compiled and summarized the largest dataset to date on the cladocerans of the Republic of Tyva—the result of almost thirty years of field work in the region (1993–2022). A total of 902 water bodies of various types were surveyed: permanent and temporary, differing in depth, altitude, and salinity.
Taiga
Mongun-Taiga is the highest mountain in Tyva
It is important to note that only a few of the lakes located in the basins can be reached by a comfortable road. Most of the water bodies are situated in the mountains, in hard-to-reach areas with difficult mountain roads. The work was incredibly labor-intensive but also exhilarating: our cars broke down high in the mountains far from any settlements, we experienced earthquakes, we had to spend nights near ancient burial mounds, wolves walked near our camp, and marals would occasionally approach us. We even once had to run quickly high in the mountains to escape a thundercloud whose lightning was striking the ground.

On one occasion, we fell into a glacial quickstream. These formations, which occur near high-mountain lakes due to the melting of relict ice, suck you into the depths like quicksand, and are incredibly difficult to escape! So this dataset is inextricably linked with a whole series of adventures.
The final dataset, published in Darwin Core Archive format on GBIF, includes 3,599 occurrence records and 76 species of cladocerans. It is noteworthy that not a single invasive species was found in Tyva, although such finds are not uncommon in studies of cladocerans in other regions.

The obtained materials significantly expand the understanding of the composition and spatial distribution of cladocerans in Tyva, which was previously poorly studied from a faunistic perspective.
Nadezda Kirova and Toby
A special mention must be made of the constant members of our expedition team — Toby the dog, who took part in the annual field trips from 2011 onward, growing from a playful puppy into a wise “scientist dog,” and Karkusha the raven, who joined us in 2016 after we found him as a chick with broken legs and decided to keep him. Without exaggeration, both became an integral part of the long-term history of our fieldwork and made their own contribution.
Toby passed away in November 2025, shortly after our research paper was published, at the age of fourteen. It would not be an overstatement to say that he truly devoted his life to these studies, accompanying us year after year and becoming a symbol of the expedition itself.

At ECN 2025, Pensoft spotlighted its journals in entomology, particularly the newly launched diamond open-access journal Natural History Collections and Museomics (NHCM), which welcomes research on the preservation, digitisation and analysis of natural history collections. Building on last year’s successful collaboration, the meeting again highlighted the Topical Collection “Entomological Outreach Collections and Community Engagement,” published in NHCM and inspired by the 2024 ECN programme.
Entomology 2025
Pensoft joined more than 3,200 insect science professionals at the Entomological Society of America’s annual meeting, Entomology 2025 (Ento2025), hosted at the Oregon Convention Center. Over four days, the conference offered symposia, workshops, networking sessions, mixers and a busy exhibit hall.
Pensoft showcased the EU pollinator projects VALOR and AGRI4POL at Entomology 2025.
Pensoft exhibited at booth #715, showcasing the publisher’s portfolio of entomology journals and promoting two key EU-funded projects on pollinators: VALOR and AGRI4POL. Featuring professional scientific illustrations, attractive open-access publishing opportunities, and results from Pensoft-partnered EU projects, the booth attracted considerable interest from attendees.
A highlight of Pensoft’s presence at Entomology 2025 was the participation of Lars Straub, Editor-in-Chief of the newly launched Diamond Open Access journal Advances in Pollinator Research (APR). Straub moderated two student 10-minute presentation competitions and presented his own research, “Neonicotinoid exposure reduces fitness of a widespread butterfly, Vanessa cardui.”

Following a fantastic week in Portland at both ECN 2025 and Entomology 2025, Pensoft looks forward to continuing its close collaboration with the entomological and collections communities. The Entomological Society of America’s next annual meeting, Entomology 2026, will take place on 8–11 November in Columbus, Ohio, where Pensoft plans to create more partnerships and continue its support for open science in insect research.
Published in the journal Subterranean Biology, the paper has become by far the most popular research article ever published across Pensoft’s scientific journal portfolio in terms of both news media coverage and overall online attention.
Issue 53 (2025) of Subterranean Biology, where the spider megacolony paper was published.
Thanks to an integration with our partners at Altmetric, we have quantifiable metrics that measure just how exceptional the attention to this article is. The paper’s Altmetric Attention Score of 2254 places it in the top 5% of all research outputs scored by Altmetric globally. For less than a month, it became more popular than nearly 27,000 research papers published by Pensoft and tracked by Altmetric.
The study was covered globally by major news outlets, reaching audiences far beyond niche scientific circles. The article garnered over 2,200 online mentions linking directly to the publication, with Altmetric tracking attention from 290 news outlets specifically. The story was featured by numerous top global news organizations, including The New York Times, BBC, The Washington Post, The Independent, Die Welt and NBC News,as well as popular science publications such as Smithsonian Magazine and Science Alert.
Beyond traditional media, the study gained significant traction on various social platforms, including YouTube, TikTok and Instagram, alongside mentions on Bluesky and X.
The paper details fascinating discovery from the Sulfur Cave, which sits on the border between Albania and Greece. There, the research team documented an extraordinary spider community centered around a massive communal web spanning more than 100 square meters. This giant structure, dense enough to resemble a living curtain, is home to an estimated total of over 110,000 spiders, comprised of approximately 69,000 Tegenaria domestica and 42,000 Prinerigone vagans individuals.

Crucially, this study marks the first documented instance of colonial behavior in both of these spider species, and the first recorded case of colonial web-building in a chemoautotrophic cave environment.
This unusual coexistence, where the larger, normally predatory T. domestica does not eat the smaller P. vagans, is believed to be facilitated by the cave’s total darkness and, most importantly, the overwhelming abundance of food resources. The ecosystem is sustained entirely without sunlight through chemoautotrophy, where sulfur-oxidizing bacteria form biofilms that support invertebrates that serve as the spiders’ primary, highly dense food source. This specialized, isolated environment has also driven the evolutionary adaptation of the spiders, which are genetically distinct from their surface relatives, illustrating the remarkable genetic plasticity that emerges under extreme environmental conditions.
We are proud that our journal Subterranean Biology is the platform for publishing such globally compelling research. This record success only confirms the widespread interest in high-quality, specialized scientific discoveries.
We continue our dedication to effective, high-reach science communication and look forward to sharing other compelling research with both scientists and the wider public.

Held from the 9th to 15th of September 2025, the event brought together over 10,000 participants from 189 countries under five central themes: Scaling Up Resilient Conservation Action; Reducing Climate Overshoot Risks; Delivering on Equity; Transitioning to Nature-Positive Economies and Societies; and Disruptive Innovation and Leadership for Conservation.
Represented by Prof Lyubomir Penev (Founder and CEO), Maria Kolesnikova (Marketing and Sales Manager), and Denitsa Peneva (Scientific Illustrator), Pensoft took part in the Congress with a dedicated booth, engaging attendees in conversation about how open science, innovative publishing, and collaborative research can drive conservation.

Pensoft’s exhibit placed a strong emphasis on restoration and ecological research, showcasing the publisher’s active role in international initiatives supporting biodiversity recovery and sustainable ecosystem management. Numerous illustrated materials were available for attendees to browse through and take home.
A key feature of the booth was Pensoft’s participation in Horizon 2020 projects such as REST-COAST, which aims to restore and safeguard coastal ecosystems through innovative, large-scale nature-based solutions. Alongside the company’s project involvement, visitors explored Pensoft’s diverse range of open-access journals, including Nature Conservation, One Ecosystem, Estuarine Management and Technologies, NeoBiota, and the newly launched Individual-based Ecology.
