Beneath the arid pre-Saharan zone of Morocco lies Aziza Cave, also known as Kef Aziza or Tazouguert Cave. The vast subterranean system stretches over 3.5 kilometers of surveyed galleries, making it Morocco’s fifth-largest cave system and one of the top ten most extensive caves in North Africa.

Beyond its sheer size and geological significance, Aziza Cave harbors a rich and diverse array of subterranean life that is only now beginning to be revealed widely. In a recent study in the journal Subterranean Biology, researchers cataloged the subterranean fauna of Aziza Cave and provided a detailed checklist of 26 different taxa potentially representing cave-restricted species. Among these are 22 troglobitic species, organisms that have adapted to life entirely within the cave environment, and four stygobitic species, which have specially evolved to live in the cave’s groundwater.

The discovery of such a variety of species highlights the cave as a critical biodiversity hotspot, not only in Morocco but for the African continent as a whole. One alarming aspect of this discovery is the large number of species that still need to be thoroughly studied or described.

Only about 34.6% of the species in Aziza Cave have been formally identified and described by scientists. Further research could lead to the identification and description of many new species. The fauna found in Aziza Cave includes a wide variety of life forms, with the richest groups being beetles (Coleoptera), spiders (Araneae), springtails (Entomobryomorpha), and woodlice (Isopoda). Some have evolved remarkable adaptations to their lightless, nutrient-scarce environment, such as reduced pigmentation, elongated appendages, and heightened sensory capabilities that help them navigate and survive in this extreme habitat.

Despite these discoveries, much of Aziza Cave remains unexplored. Large portions of this karstic system have yet to be surveyed, and researchers believe that the biodiversity uncovered so far is just the beginning. The cave’s unexplored depths likely hold many more secrets, including potentially new species that have yet to be seen by human eyes. This prospect has sparked great interest among speleologists and conservationists, who see Aziza Cave as an important research site for studying subterranean ecosystems.

The biodiversity of Aziza Cave is something to celebrate, but it also sheds light on the significant conservation challenges that subterranean habitats in Morocco and across North Africa are facing. Caves are delicate ecosystems that are highly sensitive to changes in their environment. Human activities such as pollution, mining, deforestation, and unsustainable tourism pose severe threats to these ecosystems and the species that depend on them. Once these habitats are damaged or destroyed, it is often impossible to restore them, and the species that inhabit them may face extinction.

Human-induced impacts have already begun to take their toll in Aziza Cave. Visitors can disrupt the delicate balance of the cave’s ecosystem, change water quality, or introduce pollutants and alien species. These pressures underscore the urgent need for conservation measures to protect this unique environment and its inhabitants. By highlighting the importance of Aziza Cave and similar habitats, the researchers hope to encourage further exploration and study of Africa’s subterranean ecosystems and develop effective conservation strategies to protect them. By protecting these fragile ecosystems and supporting scientific exploration, we can ensure that the incredible biodiversity of Aziza Cave and other subterranean habitats continues to thrive.

The thin, flexible, and mobile ovipositor of some female insects, perfected over thousands of years of evolution, can carry substances and drill into various substrates. Although its structure is well studied, many of its functions remain a mystery.
Researchers from Saratov State University and Moscow State University spotted interesting, unusual oviposition behaviour in the parasitoid wasp Eupelmus messene: it used its ovipositor to drill through the wall of a polystyrene Petri dish and lay an egg outside the dish.
Drilling with the ovipositor through a plastic wall of a Petri dish by Eupelmus messene (A), a newly laid egg into the external environment (B), and UV fluorescent biological substance inside the perforations (C). ov – ovipositor, per – perforation, egg – egg.
This is the first time such behaviour has been observed and recorded.
E.messene is a parasitoid of the gall wasp Aulacidea hieracii, which forms a gall on the stems of the hawkweed Hieracium×robustum. The female of E.messene then drills the walls of the gall with its ovipositor in search of a gall wasp larva and, upon finding it, lays an egg next to it.
The researchers reared 56 females from galls of H.×robustum collected near Saratov, Russia. Of them, they placed 18 in Petri dishes without host galls, and later observed five of those wasps drilling into the walls of the Petri dishes.
The team followed the behaviour of one wasp: drilling each perforation in the polystyrene wall took more than two hours, during which the insect often paused to eat, drink water, or wash. In the end, it managed to completely pierce the plastic wall and lay an egg on the outside of the Petri dish. It drilled multiple holes, even after being transferred to a different Petri dish.

“We distinguished four steps of drilling: pushing movements, rotational movements, ejection movements, as well as the cementing step. However, in natural gall, we never observed ejection movements. We suppose that such a type of movement is required to rake out plastic particles, which is unnecessary for more elastic plant gall substrate,” write the authors in their study, which was published in the Journal of Hymenoptera Research.
After laying the egg, the female carefully cemented the drilled perforation with an unknown biological substance, likely to keep it safe from the impacts of changing temperatures, water, and microorganisms.
Unlike galls, which usually have an opaque and dense structure, the transparent Petri dish provided a clear view of the whole drilling and oviposition process, allowing the researchers to study it closely.
It is still unknown why the wasp behaved this way, but the scientists believe we can learn a lot from this observation: “Studying in detail the drilling behavior of parasitic mycrohymenopterans can be useful in medicine for the creation of minimally invasive guided probes in neurosurgery, the development of orthopedic surgical instruments, needle biopsies using functionally graded tools,” they write in their paper.

Jake Lewis, an entomologist in the Environmental Science and Informatics Section at the Okinawa Institute of Science and Technology (OIST), is fascinated by weevils, a diverse group of beetles that includes many species with elephant trunk-like mouthparts (called a rostrum). Weevils provide various ecosystem services such as pollination and decomposition, but some species are serious pests known to decimate crop fields and timber forests.

Using x-ray microtomography, a 3D imaging technique that uses x-rays to visualize cross sections of the internal structure of objects, Lewis and his collaborators digitally removed scales that cover the cuticle of the weevils. They found that the underlying cuticle differs significantly between species and can therefore be used for taxonomic and classification purposes. Using this technique in combination with traditional light microscopy and DNA barcoding, they discovered, described, and named 12 new weevil species from Japan, Malaysia, Vietnam, and Taiwan. These species range from 1.5 – 3.0 mm in length and are comparatively quite small weevils.
Two of these new species are present in Japan: Aphanerostethus magnus (Oo-daruma-kuchikakushi-zoumushi) and Aphanerostethus japonicus (Nippon-daruma-kuchikakushi-zoumushi). One of these, Aphanerostethus japonicus, is also found in Yanbaru National Park, Okinawa. This is the first time x-ray microtomography has been used to remove obscuring scales to examine underlying differences in morphology for taxonomic purposes. The findings from this study have been published in the open-access journal ZooKeys.

The researchers showed that removing scales using x-ray microtomography reveals significant morphological differences between species, which cannot be easily observed using other methods. Consequently, this technique may gain more popularity as a tool for identifying new insect species, especially those covered in scales or debris.
Lewis, OIST’s Insect Collection Manager and lead author of the paper, examined specimens from collections in Canada, Germany, Japan, Malaysia, Taiwan, and the Netherlands. One of the primary goals was to investigate the use of x-ray microtomography as a tool in weevil taxonomy. The genus Aphanerostethus was poorly studied in the past, but many undescribed species were discovered in museum collections around the world, including the two new species from Japan.
X-ray microtomography generated 3D models of weevil species from the genus Aphanerostethus with the right elytron (forewing) removed, revealing differences in the length, width, and pattern of veins in the hindwing. A lateral view of the full body is shown below each closeup for reference. The red, blue, and yellow arrows indicate the base, midpoint, and apex of the hindwing, respectively.

Multiple methods to find new species
The researchers used traditional methods such as light microscopy and dissections to observe differences between species, including the scales along the elytra (back), leg spines, and the shape of the rostral canal (a canal that protects the rostrum). They also used DNA barcoding to analyze their genes and create a phylogenetic tree of eight of the species. Some species were not as easy to separate based on morphology alone, but as the gene sequences differ between species, the phylogenetic tree was informative and provided additional evidence of new species.

This helped Lewis and his team verify their predictions about species classification by using DNA analysis instead of only physical traits.

Although the above methods are standard practice in taxonomy, the researchers’ use of X-ray microtomography was novel and was successfully used to examine the structure of not only the hidden cuticle, but also the hindwings. Aphanerostethus weevils have lost the ability to fly due to the gradual reduction of their hindwings, however the degree of reduction was shown to differ between species. Normally, specimens would have to be dissected to view the hindwings, but because x-ray microtomography allows for non-destructive examination of internal anatomy, it is invaluable when working with rare or precious specimens that cannot be dissected or altered.

The presence of partially reduced wings in some species offers a fascinating glimpse into the ongoing process of evolutionary change: “Some species have almost completely lost their hindwings, while others still have non-functional half-wings with remaining vein patterns. The differing degrees in hindwing loss is not only useful for taxonomy and systematics, but also shows how different species within the same group can be at different stages of losing a historically highly important organ that played a crucial role in insect evolution,” Lewis explained.
Investing in Japan’s natural heritage
The discovery of new weevil species can be challenging for two main reasons. Firstly, weevils are incredibly diverse, making complete cataloging time consuming and tedious. Secondly, many weevil species are highly host-specific, may only inhabit very particular microhabitats, and may only be active for a short period of time as adults. For example, some species feed on a single tree species and may only occupy a certain part of a tree, such as the canopy. Furthermore, some species of weevils are strictly nocturnal and rarely observed during the daytime.

This extreme specialization and variation in natural history means that unless researchers investigate at night and day, across seasons, and focus on specific parts of many different plant species, they will inevitably overlook certain species.
Dr. Dan Warren, a research fellow at the Gulbali Institute for Applied Ecology and former leader of the Environmental Science and Informatics Section, emphasized the importance of investing in specimen collections: “These specimen collections are crucial for discovering new species and documenting biodiversity changes, both from human activities and natural cycles. They are essential tools for scientific research and conservation biology,” he stated. “Without proper support for them and the people who maintain them, we risk losing irreplaceable information on species and ecosystems, potentially before we even discover them.”

“These new weevil species are part of Japan’s natural heritage, and although still poorly known ecologically, discovering and naming them is the first step towards an understanding of their biology,” Lewis added. Protected areas like Yanbaru National Park, home to the newly discovered A. japonicus, are essential to the protection of the island’s rich and endemic biodiversity.

Decades after it was first found in Japan, a species of crustacean with unique black-and-white coloring that resembles a panda has been confirmed to be new to science. Melitid amphipods are shrimp-like crustaceans found worldwide. The newly classified Melita panda — named after the charismatic mammal — was first found in the 1990s. Details of the discovery and morphological analysis were published in a ZooKeysarticle on 21 September.

The discovery of the Melita panda highlights the importance of studying species taxonomy, which is the naming and classification of organisms, for conservation efforts. It is impossible to know if a species is in danger of disappearing if it hasn’t even been identified.
“Despite the fact that biodiversity conservation is a global issue, species diversity and other aspects of biodiversity are still not fully understood. As a first step toward species conservation, we conducted a taxonomic study of amphipod Crustacea, which boasts high species diversity around Japan,” said Ko Tomikawa, a professor at Hiroshima University’s Graduate School of Humanities and Social Sciences in Hiroshima, Japan.

Before the discovery of Melita panda, there were 63 known species of Melita amphipods, with 16 of those found in Japan. Melita panda was found in intertidal waters in Wakayama Prefecture, Japan. There are likely even more unidentified and undescribed species of Melita amphipods in Japan’s coastal waters.
“Study on the amphipod Crustacea in the coastal zone of Japan is lagging behind. In order to accurately assess species diversity, taxonomic studies are necessary. We hope the discovery of a new species of amphipod with the familiar coloring of the panda pattern will increase the public’s interest in biodiversity and taxonomy,” said Tomikawa.

To identify the Melita panda, researchers did both a morphological study and molecular phylogeny using genomic DNA. The morphological description of Melita panda found unique features including its panda-like colors and other physical characteristics, while molecular phylogeny is used to identify how closely related the Melita panda is to other Melita amphipods. This information is used to create a phylogenetic tree or evolutionary tree of the known Melita amphipods. Phylogenetic trees are diagrams that show the evolutionary relationships between species.

The molecular phylogeny found that Melita panda is closely related to two other Melita amphipods, the Melita nagatai and Melita koreana. The panda-like coloring distinguishes Melita panda from these two other amphipods, along with other physical differences. Its gnathopods, which are claws that extend from the second thoracic segment, sit more forward than other Melita amphipods, covering another one of its appendages. Its setae, which are hair-like structures that look like bristles, are also distinguishable from other Melita amphipods. Together, the Melita nagatai, Melita koreana, and newly discovered Melita panda form a monophyletic group. This means they have a common evolutionary ancestor. In this case, it is the Melita hoshinoi.
Looking ahead, researchers will continue to study the Melita panda.
“Hopefully, a detailed study of the ecology and behavior of Melita panda will reveal the reason for its panda pattern,” said Tomikawa.
Beyond Melita panda, Tomikawa emphasized that there is still more to study.
“Further taxonomic studies on amphipods in uninvestigated areas are expected to lead to the discovery of additional new species. Continued taxonomic studies are expected to elucidate the biodiversity in the coastal environments of the Japanese archipelago and provide important basic data for species conservation,” he said.

All available information on Enchodelus species is brought together. This will contribute to a more complete assessment of species diversity and distribution.
Guest blog post by Milka Elshishka and Vlada Peneva
The order Dorylaimida is the most diverse nematode group, with over 2640 valid species and more than 260 valid genera, with new taxa being described each year. They are the richest nematode order in number of species in natural soils. Dorylaims are often regarded as good environmental bio-indicators since the number of species/specimens drastically decreases following any significant disturbance in their habitat.
In our study, published in the Biodiversity Data Journal, we examined one intriguing free-living dorylaimid nematode taxon: the genus Enchodelus which is considered to have conservation value. The genus currently includes 28 species, which display a distinct distributional pattern, being spread mainly in high altitudinal enclaves of the Northern Hemisphere (with the exception of E. brasiliensis, only known to occur in Brazil). Its representatives are often associated with mosses and cliff vegetation. Although their feeding habits have not been studied with experimental protocols, it is traditionally assumed that they are omnivorous.
Distribution of Enchodelus species
The genus Enchodelus has not been recently revised; the descriptions of many ‘old species’ (that have been described long ago and have not been reported since their original discovery) are of poor quality, hardly discoverable, and do not conform to today’s taxonomical standards.
An Enchodelus species.
Actually, information available from databases often is limited to some of the species and usually incomplete as relevant data are missing. Consequently, a comprehensive compilation and analysis of literature data is indispensable to reach new insights into the taxonomy of the genus and to elucidate its evolutionary relationships.
Our work provides a cyber catalogue of Enchodelus species, where all available data for the species are accessible and collected in one place, which will greatly facilitate future research. It compiles available information from key European Research Infrastructures, such as TreatmentBank, the Swiss Institute of Bioinformatics Literature Services (SIBiLS), the Catalogue of Life (CoL), the Global Biodiversity Information Facility (GBIF), the European Nucleotide Archive (ENA) and the Biodiversity Literature Repository (BLR). Data about their distribution (geographical records and habitats) are incorporated too and all brought together. It is completed with discussion and notes for some species, along with information on species distributions and microhabitats.
Here, all available information on Enchodelus species is brought together. This will contribute to a more complete assessment of species diversity and distribution and support further biogeographical and ecological research.
The type species Enchodelus macrodorus is the most widely spread and reported Enchodelus species. It is a typical member of Palearctic nematode fauna, recorded in a myriad of countries and habitats and very sporadically recorded in Nearctic and Indomalayan enclaves. In our study we add new morphological and molecular data for this species collected from Spain.

Additionally, type material of Enchodelus vestibulifer, belonging to Edmond Altherr’s collection, deposited at the Museo Cantonale di StoriaNaturale di Lugano (Switzerland), is re-examined.
Enchodelus vestibulifer
This species was described by the Swiss nematologist Edmond Altherr in 1952 on the basis of a single female from Switzerland and no later record of it exists. The re-examination of this material revealed that several relevant traits are not compatible with those characterising the genus Enchodelus and we considered it as incertae sedis.
In our study we also present one new species, Enchodelus enguriensis. It was collected from moss on stone (Tortellasquarrosa) in Caucasus, Georgia (Samegrelo-Zemo Svaneti Region, Bogreshi, Enguri River, Tower of Love). The description of the new species was supported by a comprehensive phylogenetic analysis based on D2-D3 of 28S rRNA. When naming the new taxon, we selected the name of the place from which the material was collected, namely the River Enguri; it was recovered from the stone next to the Tower of Love on the bank of the river.

Founded in 1857 as the Berliner Entomologische Zeitschrift, Deutsche Entomologische Zeitschrift (DEZ), stands as one of the world’s oldest continuously published entomological journals. Throughout its 166-year history, DEZ has weathered significant challenges, navigating two world wars and internal societal divisions, consistently re-emerging to contribute to insect systematics.
In 2014, the journal transitioned to Open Access publishing under the auspices of Pensoft. Through this partnership, DEZ embraced a publishing model dedicated to transparency and global accessibility, making its content freely available to anyone, anywhere in the world.
As we celebrate 10 years of Open Access for the journals of Museum für Naturkunde Berlin (MfN), we look at some of the most interesting insect research published in the journal in the past decade.
Read our blog post celebrating 10 years of Open Access for all of Museum für Naturkunde Berlin’s journals here.
Caribbean pygmy jumping leaves
Published in 2023, one of DEZ’s most popular recent papers discusses the Caribbean pygmy jumping leaves, a tribe of pygmy grasshoppers called Choriphyllini. Their taxonomy has been historically confusing, with many unrelated but similar-looking tetrigids (pygmy grasshoppers) being grouped together. Authors Josip Skejo and Niko Kasalo call this group of leaf-resembling insects “a lovable mess,” referring to their confused taxonomy.
With common names such as “Jamaican Bitten Jumping Leaf” or “Old Cuban Dancing Leaf”, these insects are attractive to both researchers and laypeople.
Valalyllum folium, a member of the tribe Valalyllini, subfamily Cladonotinae.
“We can only guess what the future holds for these neglected animals,” the authors said, concluding their paper. Will we see another paper in DEZ dealing with pygmy jumping leaves?

Barcoding Taiwanese leaf litter beetles
Another important study published in DEZ focused on beetles found in Taiwan’s leaf litter. Researchers Martin Fikácek and Fang-Shuo Hu said that leaf litter is like an underwater coral reef, in that they support a huge amount of life that we don’t know much about. This is what motivated the Taiwanese Leaf Litter Beetles Barcoding project, a research effort aiming to create a DNA barcode library for the beetles that inhabit the forest floor in Taiwan.
As a rule, studying leaf litter beetles presents a number of challenges due to their vast numbers, diminutive size, and high endemism, but the DNA barcoding approach allows for faster, easier species identification. In their 2024 study in DEZ, the researchers reported the publication of 953 DNA barcodes of forest leaf litter beetles from central Taiwan, in total representing 334 species of 36 beetle families.

Revising Tropopterus
Tropopterus spp.
Having received more than 33,000 views, the paper titled “Revision of Tropopterus Solier: A disjunct South American component of the Australo-Pacific Moriomorphini (Coleoptera, Carabidae)” is the most popular DEZ article of the last decade.
Sole author Dr James K. Liebherr of Cornell University has published numerous important papers on beetle taxonomy in the journal, garnering close to 100,000 total views.

Established as Mitteilungen aus dem Museum für Naturkunde in Berlin, Geowissenschaftliche Reihe in 1998, the journal welcomed its 25th birthday last year, and today celebrates ten years of Open Access (OA) publishing. Unlike its sister journals, Fossil Record did not immediately partner with Pensoft upon its transition to OA. However, in 2022, following eight years of successful collaboration, Pensoft began publishing the journal on behalf of MfN.
In this blog post, we take a look back at some of the research that has defined Fossil Record’s Open Access era.

The most cited paper published in Fossil Record’s Open Access era is “The fossil history of pseudoscorpions (Arachnida: Pseudoscorpiones)” from 2017.
The paper reviews the sparse fossil record of pseudoscorpions, tiny arachnids first documented 390 million years ago. Most fossils are suspended in amber, preserving the specimens remarkably well.

With 21 citations, the 2022 paper “First fossil species of ship-timber beetles (Coleoptera, Lymexylidae) from Eocene Rovno amber (Ukraine)” is a great example of a highly cited recent paper.
Asked about the success of his team’s research, corresponding author of the paper Evgeny Perkovsky said: “finding this beetle in the Eocene of Ukraine indicates a very specific fossil climate, which explains a high visibility of the paper.”

The “accidentally discovered” ancient shark
The study attracted significant media attention.
Perhaps the most sensational publication in Fossil Record came when palaeontologist Jun Ebersole stumbled upon a 100-year-old box of teeth at the Geological Survey in Alabama, USA, which led to the discovery of a ‘new’ ancient shark species.
“A new species of Palaeohypotodus Glückman, 1964 (Chondrichthyes, Lamniformes) from the lower Paleocene (Danian) Porters Creek Formation, Wilcox County, Alabama, USA” was published in 2024 and attracted significant public and scientific attention.
Describing the study, T. Lynn Harrell Jr., one of the authors said: “this time period is understudied, which makes the discovery of this new shark species that much more significant.

For a journal with more than 125 years of history, a single decade may seem like a mere drop in the ocean. However, the last ten years have been significant for Zoosystematics and Evolution (ZSE) as they have seen the historic Museum für Naturkunde Berlin (MfN) journal transition to an open-access publishing model.
Established in 1898 as Mitteilungen aus dem Museum für Naturkunde in Berlin Zoologische Reihe, ZSE is one of the oldest zoological journals in Europe. But far from falling behind the times, the journal partnered with Pensoft in 2014 to make their research available and free to all. The move marked the beginning of a new era, enhancing the journal’s global reach, accessibility, and influence.
Here we take a look back and celebrate some of the publications that have defined Zoosystematics and Evolution’s decade of Open Access with Pensoft.
Read our blog post celebrating 10 years of Open Access for all of Museum für Naturkunde Berlin’s journals here.

ZSE’s most popular article, “A new species of green pit vipers of the genus Trimeresurus Lacépède, 1804 (Reptilia, Serpentes, Viperidae) from western Arunachal Pradesh, India” has been viewed more than 47,000 times at the time of writing.
Published in 2020, the article drew major mainstream attention due to the scientific name of the new species, Trimeresurus salazar, which was inspired by Salazar Slytherin of the Harry Potter franchise.
Spectacular pictures of the species accompanies the article, undoubtedly contributing to the success of the Indian researchers’ publication.
On his decision to publish with ZSE, lead author Zeeshan Mirza of the Max Planck Institute for Biology Department of Integrative Evolutionary Biology said: “Zoosystematics and Evolution is a reputed journal of the Museum Für Naturkunde, and I was happy that my work was published in it. I like the simple and excellent layout and the smooth experience throughout the article’s publication process.”

A ‘cute but deadly’ discovery
Recent years have seen an influx of media attention for research published in ZSE. A fantastic recent example of this came when a newly discovered velvet worm species was published in the journal.
More than 20 years in the making, the 2024 discovery represented the first study of Ecuadorian velvet worms for over 100 years. The cute appearance and fascinating behaviour of the species attracted plenty of attention from news outlets and social media users.
Describing the study, Diego Cisneros-Heredia, one of the authors and director of the USFQ Museum of Zoology, Ecuador said: “The research on this new species took several decades. I discovered the first individual of this new species in 2001, and we finally managed to describe it as part of Jorge Montalvo’s graduation thesis.
“To complete the description, we used not only macromorphological descriptions but also high-magnification images obtained with a scanning electron microscope.”

The League of Legends crab
While this crab discovered in coral reefs of the South China Sea may seem unassuming, it gained hundreds of thousands of views, likes and shares when it was published just a few months ago.
In a perfect example of the global reach of open-access publishing, the paper was shared extensively on the Chinese social media platform Weibo, and even resulted in Riot Games sending the lead author a goodie bag!

By adopting Open Access in 2014, Museum für Naturkunde Berlin (MfN) took an important step towards ensuring the research published in its journals can reach scientists, members of the public, and key decision-makers across borders.
Beginning with the two oldest journals, Zoosystematics and Evolution (ZSE) and Deutsche Entomologische Zeitschrift (DEZ), Pensoft began publishing research on behalf of MfN a decade ago, utilising professional expertise and the cutting-edge digital publishing tools of the ARPHA platform to increase the visibility and engagement of the journals.
Now, ten years and another journal later, Pensoft and MfN celebrate a decade of Open Access collaboration and look back on many years of success.
Zoosystematics and Evolution
Zoosystematics and Evolution (ZSE) holds a prestigious place in the history of zoological science. Established in 1898 as Mitteilungen aus dem Museum für Naturkunde in Berlin Zoologische Reihe, it is one of the oldest zoological journals in Europe and continues to publish exciting research to this day led by Editor-in-Chief Dr Thomas von Rintelen.
The first Open Access issue of ZSE, published by Pensoft.
The journal’s 2014 transition to an open-access (OA) model under the publishing expertise of Pensoft marked the beginning of a new era, enhancing its global reach, accessibility, and influence.
A recent issue of ZSE, published by Pensoft.
Over the years, Museum für Naturkunde Berlin, has covered entire article processing charges (APCs) for authors under specific terms. This support has lowered the barrier to publication for many researchers, particularly those from institutions or regions with limited funding, thus fostering a more inclusive and diverse authorship.
The transition of Zoosystematics and Evolution to Open Access has increased the journal’s visibility and impact. The number of views and the level of publicity have surged, demonstrating the success of the move. The following graphs display how article submissions, publications and views have increased over the past decade:
Finally, growth in journal’s citation count and Clarivate Impact Factor reflect the progress that has been made in the past decade:
An international community
Over the past decade, ZSE has increasingly attracted contributions from a global pool of researchers, reflecting the journal’s expanding international reputation.
Top nationalities who have published in ZSE since 2014.
Leading the pack of the journal’s most prolific authors is Wilson Costa, who has authored 16 papers, followed by Axel Katz, Frank Glaw, Mark-Oliver Rödel, and Davut Turan, each with 11 papers.
The journal’s editorial and review processes have also seen robust participation. Nicholas Hubert stands out as the most active editor, having handled 71 papers, with other prominent editors like Danilo Harms and Matthias Glaubrecht contributing significantly. The review process has been equally supported by dedicated reviewers such as Donald Taphorn and Felipe Ottoni, ensuring the maintenance of high academic standards.
Public engagement
The journal’s shift to Open Access has not only increased its academic reach but also its presence in news and social media. Since the journal moved to an OA model, numerous studies have attracted stories from major news publications such as the BBC and the Guardian.
ZSE has effectively utilised platforms like Twitter/X, Facebook and Instagram to engage with a broader audience, including scientists, the general public, and unlikely collaborations like this recent post from Riot Games.
Both social media and traditional media mentions of the journal continue to rise as can be seen in the graph below:
Looking ahead
As ZSE celebrates a decade of Open Access with Pensoft, the journal stands as a testament to the power of making scientific knowledge freely accessible. The past ten years have seen ZSE not only maintain its historic legacy, but adapt and thrive in the digital age. Moving forward, the journal is poised to continue its mission of advancing zoological science, supported by a growing international community of authors, editors, and readers.
“Zoosystematics and Evolution has come a long way since becoming an Open Access journal, transforming from a journal with a significant in-house focus, both regarding authors and the editorial board, to being highly diverse in both respects. Increasingly, the amazing increase in taxonomic expertise in the regions where it is most needed is reflected in the origin of those publishing their research in the journal.
“I am glad and thankful for having been part of this transformation over the last five years and I as well as the whole editorial team are looking forward to further strengthen ZSE’s role as a sought-after platform for making taxonomic and systematic research freely available and visible over the next decade.”
Thomas von Rintelen, Editor-in-Chief.
Deutsche Entomologische Zeitschrift
Founded in 1857 as Berliner Entomologische Zeitschrift, Deutsche Entomologische Zeitschrift (DEZ) is one of the world’s oldest international journals in systematic entomology. Published by Pensoft on behalf of the Museum für Naturkunde Berlin, it aims to advance understanding of the systematics and biology of insects. Since June 2023, the journal has been led by Editor-In-Chief Dr Matthias Seidel.
In 2014, in its 157th publishing year, the journal transitioned to an open-access (OA) model under the publishing expertise of Pensoft, thanks to which “the journal has opened up to scientists from all over the world employing the wide range of tools offered by the Pensoft platform,” as stated by Dr Dominique Zimmermann, the journal’s former Editor-in-Chief.
The first DEZ issue published by Pensoft.
The move to OA aligned with the journal’s long-standing commitment to fostering knowledge sharing and accessibility, going all the way back to DEZ’s founder, Ernst Gustav Kraatz, who was a fervent proponent of inclusive and facilitated access to knowledge.
A recent DEZ issue.
The partnership with Pensoft also provided next-generation technology and innovative tools for enhancing DEZ’s discoverability and reach.
The Museum für Naturkunde Berlin generously supports the publication of 300 pages in DEZ each year, meaning dozens of entomologists get to publish in the prestigious outlet for free. This policy offers extra support to authors from underfunded institutions or regions, and in general makes for a more diverse and inclusive range of contributors.
10 years together
The transition of DEZ to Open Access has increased the journal’s visibility and impact. There has been a notable rise in both viewership and overall exposure, highlighting the effectiveness of this change. The graphs below illustrate the growth in article submissions, publications, and views over the past ten years.
Right behind it, with just under 33,000 views, is the book review of “Insect morphology and phylogeny” by the journal’s then-Editor-in-Chief Dominique Zimmermann and subject editor Susanne Randolf.
Since 2014, the journal’s Impact Factor has more than doubled, standing at 1.3 and making DEZ very attractive to amateur and academic entomologists.
Going global
Over the last ten years, DEZ has drawn more submissions from researchers worldwide, highlighting the journal’s growing recognition on an international scale.
Top nationalities who have published in DEZ since 2014.
DEZ’s scientific community also engages strongly with the journal’s editorial and review processes, contributing their expertise and insights to ensure the publication of high-quality peer-reviewed research. Dominique Zimmermann, with 52 manuscripts, is the most prolific editor, while Susanne Randolf is the most active reviewer, with 8 reviewed manuscripts.
Connecting with insect lovers
The journal’s transition to an Open Access model has expanded its visibility beyond academic reach. For the past 10 years, there have been 2,300 mentions of DEZ articles in mainstream and social media.
Mentions of Deutsche Entomologische Zeitschrift in both social and traditional media have been steadily increasing since it opened the access to its articles.
DEZ constantly reaches out to researchers and the wider community, maintaining a presence on social media platforms such as Twitter/X, Facebook, and Instagram, in an effort to highlight the importance of taxonomic research.
DEZ’s transition to an Open Access model under Pensoft in 2014 marked a significant milestone in its commitment to open science principles and knowledge dissemination. Going forward, DEZ aspires to continue upholding its high editorial standards, promoting rigorous research, and facilitating scientific exchange on a global scale. By embracing innovative technology, DEZ aims to remain a leading scholarly outlet for entomological research, fostering collaboration, transparency, and accessibility.
The youngest of MfN’s journals, Fossil Record was founded in 1998 under the name Mitteilungen aus dem Museum für Naturkunde in Berlin, Geowissenschaftliche Reihe. The palaeontological journal, now led by Editor-in-Chief Florian Witzmann, followed ZSE and DEZ in 2022 by partnering with Pensoft in an open-access collaboration.
The publication of articles in Fossil Record is generously supported by funding from the Museum für Naturkunde, Berlin, who cover all article processing charges until their yearly budget is exhausted.
A new era
Since Fossil Record’s move to OA, the journal has enjoyed an increase in submissions, publicity and research impact.
Like all of MfN’s journals, Fossil Record boasts a wealth of international authors and actively encourages researchers from underrepresented nations to consider them for publication.

Baring bones
Fossil Record’s Open Access model promotes the sharing of and engagement with interesting research featured in the journal.
Using platforms such as Twitter/X, Facebook and Instagram, the journal promotes attractive and important research to professionals and enthusiasts alike.
Fossil Record’s 2014 transition to Open Access reinforced the journal’s dedication to open science. Looking ahead, the journal is committed to maintaining its high editorial standards, encouraging robust research, and enhancing global scientific communication. By adopting cutting-edge technologies, Fossil Record seeks to remain a premier platform for paleontological studies, promoting collaboration, transparency, and greater accessibility.
“On the 10th anniversary of the Fossil Record’s Open Access, it is clear that the path we have taken has been a great success. Fossil Record is a firmly established name among the best palaeontological journals and is attracting more and more authors and readers from all parts of the world. It is to be hoped that the journal will continue on this path in the future and remain a guarantor of high scientific standards and free access to scientific knowledge.”
Florian Witzmann, Editor-in-Chief
The decade ahead
In celebrating a decade of Open Access partnership between Museum für Naturkunde Berlin and Pensoft, the success of this collaboration is evident across the three journals.
Over the past ten years, the Open Access model has significantly increased the visibility, accessibility, and impact of research, fostering a more inclusive and international scientific community. As these journals continue to thrive, they remain committed to advancing knowledge sharing, scientific integrity, and global collaboration, ensuring a bright future for open-access publishing in their fields.
“We are proud to commit to the advancement of biodiversity research by providing open access to our journals. We believe that freely available scientific knowledge is crucial for fulfilling our vision to develop an open knowledge infrastructure for nature that promotes multi-perspective thinking and action. This includes awareness-raising work, infrastructure and services provision for researchers as central tasks of the Coordination Office for Scientific Publishing. I would like to thank Stefanie Paß and Clara Schindler from the Coordination Office, who work with great commitment and passion to promote open access and advance the journals as a research-oriented service that will be expanded even further in the future in order to extend its impact.”
Dr Frederik Berger, Head of Service & Impact Collection Future, MfN
“Back in 2014, Museum für Naturkunde Berlin became the first natural history institution to trust us with the publication of its very own journals as they moved to Open Access. Needless to say, as an open-access-born publisher whose roots lie in the science of natural history, this was a great honour, and we are delighted with its flourishing ever since. As much as we enjoy reflecting on what we have achieved together, we already have our eyes set on building on our partnership and sharing lots of novel discoveries and quality research with the wide world!”

Once you know where to look for them, lichens are everywhere! These composite organisms – fungal and photosynthetic partners joined into a greater whole, can survive on a vast array of surfaces, from rocks and trees to bare ground and buildings. They are known from every continent, and almost certainly every land mass on planet Earth; some species have even survived exposure to the exterior of the International Space Station. This hardy nature has long interested researchers studying what life could survive on Mars, and the astrobiologists studying life on Earth as an analog of our planetary neighbour. In the deserts surrounding two Mars analog stations in North America, lichens comprise such an important part of the local ecosystems that they inspired a biodiversity assessment with a unique twist: this collections-based inventory took place during a simulated mission to Mars!

The Mars Desert Research Station in Utah, USA (on Ute and Paiute Territory), and the Flashline Mars Arctic Research Station in Nunavut, Canada (in Inuit Nunangat, the Inuit Homeland) are simulated Martian habitats operated by The Mars Society, where crews participate in dress rehearsals for crewed Martian exploration. While learning what it would take to live and work on our planetary neighbour, these “Martians” frequently study the deserts at both sites, often exploring techniques for documenting microbial life and their biosignatures as a prelude to deploying these tools and methods off world. These studies are enhanced by a comprehensive understanding of the ecosystems being studied, even if they are full of Earthbound life. During the Mars 160 – a set of twin missions to both Utah and Nunavut in 2016 and 2017 – our team undertook a floristic survey of the lichen biodiversity present at each site.

During simulated extra-vehicular activities, Mars 160 mission specialists wearing simulated spacesuits scouted out various habitats at both stations, seeking out lichen species growing in various microhabitats. Collecting over 150 specimens, these samples were “returned to Earth”, and identified at the National Herbarium of Canada at the Canadian Museum of Nature. Through morphological examination, investigations of internal anatomy and chemistry, and DNA barcoding, “Mission Support” identified 35 lichen species from the Mars Desert Research Station, and 13 species from the Flashline Mars Arctic Research Station.

These species, along with photographs and a synopsis of their identifying characteristics, are summarized in a new paper out now in the open-access journal Check List. This new annotated checklist should prove useful to future crews working at both analog research stations, while also helping Earthly lichenologists better understand the distribution of these fascinating organisms, including new records of rarely reported or newly described species from some of Earth’s most interesting, and otherworldly habitats.
