The publications so far include the grant proposal; conference abstracts, a workshop report, guidelines papers and deliverables submitted to the Commission.
The dynamic open-science project collection of BiCIKL, titled “Towards interlinked FAIR biodiversity knowledge: The BiCIKL perspective” (doi: 10.3897/rio.coll.105), continues to grow, as the project progresses into its third year and its results accumulate ever so exponentially.
Following the publication of three important BiCIKL deliverables: the project’s Data Management Plan, its Visual identity package and a report, describing the newly built workflow and tools for data extraction, conversion and indexing and the user applications from OpenBiodiv, there are currently 30 research outcomes in the BiCIKL collection that have been shared publicly to the world, rather than merely submitted to the European Commission.
Shortly after the BiCIKL project started in 2021, a project-branded collection was launched in the open-science scholarly journal Research Ideas and Outcomes(RIO). There, the partners have been publishing – and thus preserving – conclusive research papers, as well as early and interim scientific outputs.
The publications so far also include the BiCIKL grant proposal, which earned the support of the European Commission in 2021; conference abstracts, submitted by the partners to two consecutive TDWG conferences; a project report that summarises recommendations on interoperability among infrastructures, as concluded from a hackathon organised by BiCIKL; and two Guidelines papers, aiming to trigger a culture change in the way data is shared, used and reused in the biodiversity field.
At the time of writing, the top three of the most read papers in the BiCIKL collection is completed by the grant proposal and the second Guidelines paper, where the partners – based on their extensive and versatile experience – present recommendations about the use of annotations and persistent identifiers in taxonomy and biodiversity publishing.
Access to data and services along the entire data and research life cycle in biodiversity science. The figure was featured in the BiCIKL grant proposal, now made available from the BiCIKL project collection in RIO Journal.
What one might find quite odd when browsing the BiCIKL collection is that each publication is marked with its own publication source, even though all contributions are clearly already accessible from RIO Journal.
This is because one of the unique features of RIOallows for consortia to use their project collection as a one-stop access point for all scientific results, regardless of their publication venue, by means of linking to the original source via metadata. Additionally, projects may also upload their documents in their original format and layout, thanks to the integration between RIO and ARPHA Preprints. This is in fact how BiCIKL chose to share their latest deliverables using the very same files they submitted to the Commission.
“In line with the mission of BiCIKL and our consortium’s dedication to FAIRness in science, we wanted to keep our project’s progress and results fully transparent and easily accessible and reusable to anyone, anywhere,”
explains Prof Lyubomir Penev, BiCIKL’s Project Coordinator and founder and CEO of Pensoft.
“This is why we opted to collate the outcomes of BiCIKL in one place – starting from the grant proposal itself, and then progressively adding workshop reports, recommendations, research papers and what not. By the time BiCIKL concludes, not only will we be ready to refer back to any step along the way that we have just walked together, but also rest assured that what we have achieved and learnt remains at the fingertips of those we have done it for and those who come after them,” he adds.
Apart from science communication, Pensoft is also tasked with the development and maintenance of the CANOPY platform, whose aim is to support policymakers and national and regional authorities
Dedicated to bridging the gap between science, policy, industry and society, Pensoft is striving to maximise ForestPaths’ impact in meeting Europe’s climate and biodiversity targets
The backdrop
The European Union (EU) has set ambitious targets to reduce greenhouse gas emissions by at least 55% in 2030 and to become climate neutral by 2050, which require urgent and major societal and economic reforms.
In the meantime, the EU also aims to protect biodiversity and reverse the degradation of ecosystems, while using natural resources to mitigate climate change.
ForestPaths – a recently started Horizon Europe project will help meet Europe’s climate and biodiversity targets by providing clear policy options that enable European forests and the forest-based sector to contribute to climate change mitigation, while conserving their biodiversity and sustaining the services they provide to people.
As an experienced science communicator, Pensoft is dedicated to maximising ForestPaths’ impact. The team will do so by means of tailored communication, dissemination and exploitation strategies aimed at sharing the project’s results with relevant stakeholder groups.
Furthermore, Pensoft is tasked with the development and long-term maintenance of the CANOPY platform, whose aim is to support policymakers and national and regional authorities by granting them access to the knowledge and scientific evidence acquired within ForestPaths long after the project is finalised.
Building on these options, the project will collaborate with policymakers and key authorities through a series of Policy labs, where the partners will co-design policy pathways, which will then be analysed with next-generation integrated assessment techniques.
Lastly, ForestPaths will apply this framework for an all-round assessment of the climate mitigation potential of European forests and the forest-based sector.

The ForestPaths legacy
ForestPaths’ policy pathways – as well as their supporting information and evidence – will be made openly available through the project’s policy-support platform CANOPY, hosted on the ForestPaths website.
The platform, whose launch is scheduled for 2026, will feature an interactive policy analysis tool explaining the policy pathways and showcasing their implications, as well as providing detailed assessment results and policy recommendations in an easily accessible manner. Its long-term mission is to become the go-to place for easily accessible assessment results and policy recommendations.
“We are excited to be doing our part for Europe’s fight for climate neutrality by extending ForestPaths reach to policy, industry and society at large! As an open-access scientific publisher engaged in about 50 environmental research projects, Pensoft echoes ForestPaths’ aim to support the EU’s climate neutrality transition through what we are sure will be a prolific international research collaboration,” says ForestPaths’ WP7 leader Anna Sapundzhieva.
For the first time, self-sustaining populations of three non-native species of turtles were identified in south-western Germany by researchers at the University of Freiburg
For the first time, self-sustaining populations of three non-native species of turtles were identified in south-western Germany by researchers at the University of Freiburg
Three species of turtles native to North America have been successfully reproducing in the wild in Germany, report for the first time environmental researcher Benno Tietz and biologist Dr. Johannes Penner of the University of Freiburg, along with Dr. Melita Vamberger of the Senckenberg Natural History Collection in Dresden.
Their results were published in the open-access scientific journal NeoBiota.
The scientists examined a total of nearly 200 animals living in the wild in lakes in Freiburg and Kehl. Their findings suggest that the turtles have established themselves in a new habitat, where they could become a threat to the local ecosystem.
For two species, this is the first evidence of independent reproduction outside of their natural reproductive range. For the third species, this is the northernmost evidence of its presence up to now,
says Penner.

Turtles released into the wild
Invasive species do a great deal of economic damage world-wide. They also contribute to advancing global species extinctions.
Alien reptiles regularly make their way into the wild in Germany. Most often, this is because they have been released by pet owners.
Large numbers of North American pond sliders (Trachemys scripta) were imported into the European Union (EU) in the 1980s and 1990s as house pets. In 1997, their import into the EU was banned. By 2016, the sale of specimens born here was also made illegal. Since then, pet shops have replaced them with other freshwater turtles, such as the river cooter (Pseudemys concinna) and the false map turtle (Graptemys pseudogeographica).
Genetic analyses of specimens of all three species in a range of ages have now demonstrated that they are reproducing independently in local waters.
What’s surprising is that the invasive species have established themselves so far north. In Europe, successful reproduction and self-maintaining populations of Trachemys scripta were only known in the Mediterranean regions and the continental climate zone of Slovenia,
explains Benno Tietz.
Until recently, it had been assumed the turtles being examined couldn’t reproduce in Central Europe due to the colder climate. Especially the false map turtle is actually quite sensitive to the cold,
he says.

Consequences for local species unclear
The invasive turtles could become a problem for indigenous species.
The European pond turtle (Emys orbicularis), for example, is now only present in Germany in parts of Brandenburg.
In an experimental setup, the European pond turtle showed weight loss and an increased death rate when being kept together with Trachemys scripta,
reports Penner.
Penner says that could be caused by the larger, alien species forcing the smaller local turtles from places where they sun themselves, leading the local turtles to have problems with thermoregulation. Or perhaps the competition led to them having greater challenges when seeking food.
Beyond that, aquatic turtles could be hosts for viruses and parasites, leading them to play a role in the spread of diseases. This could potentially have a damaging influence on other parts of the ecosystem, including amphibians, fish, or aquatic plants.
On the other hand, in their study, the researchers consider the alien species could assume functions in damaged ecosystems that would otherwise go unreplaced.
Vamberger says these questions urgently need to be explored further.
We need to raise public awareness that people should not release – no matter what kind of species – any animals into the wild in future.”
she insists.

Benno Tietz has completed a Master’s degree in Environmental Sciences at the University of Freiburg. His thesis – finished in the Winter Semester of 2020/2021 – investigated alien turtles. Currently, he is a research assistant at the Freiburg Institute of Applied Animal Ecology.

OpenBiodiv is a biodiversity database containing knowledge extracted from scientific literature, built as an Open Biodiversity Knowledge Management System.
Apart from coordinating the Horizon 2020-funded project BiCIKL, scholarly publisher and technology provider Pensoft has been the engine behind what is likely to be the first production-stage semantic system to run on top of a reasonably-sized biodiversity knowledge graph.
OpenBiodiv is a biodiversity database containing knowledge extracted from scientific literature, built as an Open Biodiversity Knowledge Management System.
As of February 2023, OpenBiodiv contains 36,308 processed articles; 69,596 taxon treatments; 1,131 institutions; 460,475 taxon names; 87,876 sequences; 247,023 bibliographic references; 341,594 author names; and 2,770,357 article sections and subsections.
In fact, OpenBiodiv is a whole ecosystem comprising tools and services that enable biodiversity data to be extracted from the text of biodiversity articles published in data-minable XML format, as in the journals published by Pensoft (e.g. ZooKeys, PhytoKeys, MycoKeys, Biodiversity Data Journal), and other taxonomic treatments – available from Plazi and Plazi’s specialised extraction workflow – into Linked Open Data.
“I believe that OpenBiodiv is a good real-life example of how the outputs and efforts of a research project may and should outlive the duration of the project itself. Something that is – of course – central to our mission at BiCIKL.”
explains Prof Lyubomir Penev, BiCIKL’s Project Coordinator and founder and CEO of Pensoft.
“The basics of what was to become the OpenBiodiv database began to come together back in 2015 within the EU-funded BIG4 PhD project of Victor Senderov, later succeeded by another PhD project by Mariya Dimitrova within IGNITE. It was during those two projects that the backend Ontology-O, the first versions of RDF converters and the basic website functionalities were created,”
he adds.
At the time OpenBiodiv became one of the nine research infrastructures within BiCIKL tasked with the provision of virtual access to open FAIR data, tools and services, it had already evolved into a RDF-based biodiversity knowledge graph, equipped with a fully automated extraction and indexing workflow and user apps.
Currently, Pensoft is working at full speed on new user apps in OpenBiodiv, as the team is continuously bringing into play invaluable feedback and recommendation from end-users and partners at BiCIKL.
As a result, OpenBiodiv is already capable of answering open-ended queries based on the available data. To do this, OpenBiodiv discovers ‘hidden’ links between data classes, i.e. taxon names, taxon treatments, specimens, sequences, persons/authors and collections/institutions.
Thus, the system generates new knowledge about taxa, scientific articles and their subsections, the examined materials and their metadata, localities and sequences, amongst others. Additionally, it is able to return information with a relevant visual representation about any one or a combination of those major data classes within a certain scope and semantic context.
Users can explore the database by either typing in any term (even if misspelt!) in the search engine available from the OpenBiodiv homepage; or integrating an Application Programming Interface (API); as well as by using SPARQL queries.
On the OpenBiodiv website, there is also a list of predefined SPARQL queries, which is continuously being expanded.
“OpenBiodiv is an ambitious project of ours, and it’s surely one close to Pensoft’s heart, given our decades-long dedication to biodiversity science and knowledge sharing. Our previous fruitful partnerships with Plazi, BIG4 and IGNITE, as well as the current exciting and inspirational network of BiCIKL are wonderful examples of how far we can go with the right collaborators,”
Biologists at Eawag have identified ten species of whitefish in the lakes of the Reuss river system. Of these, seven have been described as distinct species for the first time – although in two cases this required inspection of specimens from historical collections, since eutrophication of lakes in the 20th century also led to the extinction of fish species in Central Switzerland.
These seven whitefish were described as separate species for the first time, including the “Albeli” from Lake Lucerne, which now bears the name Coregonus muelleri in memory of the whitefish expert Rudolf Müller. Image by Eawag
The “Edelfisch” (Coregonus nobilis) was, after the smaller “Albeli”, the second most commonly caught species of whitefish in Lake Lucerne until, in the second half of the 20th century, phosphate from domestic wastewater and nutrient-rich run-off from farmland led to a massive increase in algal blooms. Compared to the lakes of the Central Plateau, nutrient levels in Lake Lucerne were moderate, and eutrophication was short-lived; even so, due to algal decomposition, oxygen was depleted in the deeper layers of the lake. The “Edelfisch”, which reproduces in the late summer at a spawning depth of 80 metres or more, suffered as a result. Shortly before nutrient inputs decreased following the ban on phosphates in detergents and the expansion of wastewater treatment plants, stocks of this species collapsed and it was considered to be extinct in 1980. Only from the late 1990s were individual specimens caught once again, unequivocally identified as C. nobilis in 2000 by the whitefish specialist and Eawag researcher Rudolf Müller.

Five whitefish species in Lake Lucerne
Coregonus nobilis, Lake Lucerne, Switzerland.
As the “Edelfisch” is now a protected species, Lake Lucerne has not lost any of its historically recorded whitefish species. Indeed, in addition to the familiar “Edelfisch”, “Albeli” and “Bodenbalchen”, Eawag scientists have identified two new species – two large whitefish, differing from the previously known species in their habits, morphological characteristics and genetic composition. The pelagic “Schwebbalchen” (Coregonus suspensus) probably lives permanently in the open water, not only for foraging but also for reproduction – a spawning behaviour only previously observed in the “Blaufelchen” (C. wartmanni) of Lake Constance. Occupying a position intermediate to the pelagic “Schwebbalchen” (C. suspensus) and the “Bodenbalchen” (C. litoralis) is the littoral “Schwebbalchen” (C. intermundia).
Lake Zug survivor
Coregonus supersum.
Particularly affected by eutrophication in the mid-20th century were whitefish in Lake Zug, which – like other Central Plateau lakes – was exposed to higher nutrient levels, for a longer period, than waterbodies further upstream. As only the uppermost water layers of this 200-metre-deep lake maintained oxygen levels sufficient to support fish, two whitefish species spawning in the depths of the lake died out – the (Lake Zug) “Albeli” (C. zugensis) and “Albock” (C. obliterus). Indeed, the Lake Zug “Albock” would have been completely forgotten if specimens had not been found by Eawag scientists Oliver Selz and Ole Seehausen in the historical Steinmann-Eawag Collection. Its morphology and historical accounts indicate that the Lake Zug “Albock” was a deep‑water specialist – a specialisation only otherwise observed to the same degree in the (likewise extinct) Lake Constance Kilch (C. gutturosus) and the (still extant) Lake Thun Kropfer (C. profundus).
The only whitefish species still found in Lake Zug today, spawning near the shore, is the “Balchen”. Testifying to its survival is its new scientific name – Coregonus supersum (“I have survived”).
Species endemic to each lake
Also new are the scientific names of the Lake Lucerne “Bodenbalchen” (C. litoralis) and “Albeli” (C. muelleri). For the morphological and genetic studies carried out by Oliver Selz and Ole Seehausen in order to revise the taxonomy of whitefish showed that almost every lake in Central Switzerland has its own species of “Albeli” and “Bodenbalchen”.
Previously, the “Albeli” of Lakes Zug and Lucerne had been classified as members of the same species (C. zugensis), while the “Balchen” spawning near the shore of the various Central Swiss lakes were known as C. suidteri. These collective species names have now been inherited by the extinct Lake Zug “Albeli” (C. zugensis) and the Lake Sempach “Balchen” (C. suidteri).
The Lake Lucerne “Albeli” received the new name C. muelleri in honour of the fisheries biologist and whitefish specialist Dr Rudolf Müller (1944–2023).

A reflection of Switzerland
The lakes of the Reuss river system are a reflection of Switzerland as a whole. Since the last ice age, at least 35 whitefish species evolved in the pre-alpine lakes, usually two or more in each lake. Switzerland lost a third of these species during the period of lake eutrophication around the middle of the 20th century. Many of the lost species are known to researchers only thanks to historical collections, such as that created before the eutrophication period by the naturalist Paul Steinmann and currently curated by the Natural History Museum of Bern.

Non-native forest tree species can reduce native species diversity if they are planted in uniform stands. In contrast, the effects of introduced species on soil properties are small. This was found by an international review study with the participation of the Swiss Federal Institute for Forest, Snow and Landscape Research WSL.
Curse or blessing? Opinions are divided on non-native tree species. In addition to native species, many foresters also plant non-native species that can withstand the increasing summer drought. In various parts of Europe, the latter are already important suppliers of timber. However, conservationists fear ecological damage, for example if native species are displaced or tree pathogens and insect pests are introduced.

Now a team of European researchers, led by Thomas Wohlgemuth of WSL, has looked at the state of knowledge on the ecological consequences of alien tree species in Europe. They analysed the results of 103 studies on seven such species. All of these studies had investigated how stands dominated by non-native tree species affected biodiversity or soil condition under the trees compared to stands of native tree species. The organisms studied included plants, mosses, microorganisms and insects from the forest floor to the treetops.
Of the seven alien species studied, only the Douglas fir is currently planted in larger numbers in the Swiss forests. While foresters used to value its fast, straight growth and its versatile wood, today they appreciate its higher drought tolerance compared to spruce. Other species are problematic because they can spread uncontrollably. The North American Robinia, for example, is invasive and can displace native species. It was already introduced in Europe 400 years ago and used in Switzerland, among other things, to stabilise soils.

Negative effects on biodiversity predominate
Across the 103 studies, the consequences of non-native species for biodiversity were negative. Comparisons from 20 studies show, for example, that on average fewer insect species live on and in Douglas fir than in spruce or beech stands. Robinia also reduces the diversity of insects, eucalyptus that of birds. This is hardly surprising, says Wohlgemuth, head of the WSL Forest Dynamics Research Unit. Because: “These results apply to comparisons between pure stands.” In continuous, uniform plantations, many alien species clearly have worse impacts than native species.
Proportion of cases with increasing (green), decreasing (red) or non-significant (grey) effects of tree species non-native to Europe on diversity attributes (abundance, species richness or diversity) of different taxonomic groups in comparison to native vegetation. Numbers of cases are shown next to the NNTs names, below the diversity attributes and above the bars.
But alien species do not only have negative impacts. Most of them do not affect soil properties. The easily degradable needles of Douglas firs can even make more nutrients available than the poorly degradable spruce needles. “When it comes only to soil properties, the Douglas fir has no negative impact,” Wohlgemuth says. In general, an equal number of studies found positive and negative effects of the seven non-native species on the soil.
Douglas firs are attractive for forestry because of their fast growth, good wood properties and – in regard to climate change – their drought resistance. Photo by Thomas Reich
Furthermore, it makes a difference whether the alien species are more closely or more distantly related to European tree species. “Tree species without closer relatives, such as eucalyptus and acacia from Australia, reduce species diversity more strongly across all studies than closely related species, such as Douglas fir and wild black cherry from North America,” adds Martin Gossner, head of the WSL Forest Entomology Group and second author of the study.
Management has a significant influence on whether Douglas fir or other tree species are good or bad for a forest overall. Uniform and dense Douglas fir stands are unsuitable habitats for many organisms. However, the same is true for spruces, which have been planted extensively for timber production in lowland areas of Central Europe over the last 100 years. On the other hand, Douglas firs in stands of native forest trees, individually or in small groups, would hardly disturb the ecosystem, Wohlgemuth says: “We conclude that the impact on native biodiversity is low with mixed-in Douglas firs.”
Should foresters plant non-native tree species or not? Despite certain negative aspects, Wohlgemuth does not recommend total renunciation. “Particularly in the case of Douglas fir, the facts show that moderate admixture in stands has little impact on native biodiversity, while at the same time preserving ecosystem services such as the production of construction timber. This is especially true when other, less drought-resistant conifers are increasingly lacking with regard to unchecked climate change.”

In Thailand, more than 1,000 caddisfly species occur, and a recent study shows that their diversity in the country is even greater than previously suggested.
Caddisflies are an order of aquatic insects with high diversity. In Thailand, more than 1,000 caddisfly species are known to occur, and a recent study in the journal Check Listshows that their diversity in the country is even greater than previously suggested.
Scientists Rungnapa Somnark from Khon Kaen University and Narumon Sangpradub from the Center of Biodiversity Excellence, Chulalongkorn University recorded, for the first time, two caddisfly species that were previously not documented as part of Thailand’s fauna. They were able to catch the insects using black-light traps set up along water streams. The field study took place in the summer of 2017 at Thap Lan National Park, which is a part of Dong Phayayen–Khao Yai Forest Complex, a Natural World Heritage site in the north-eastern Thailand.
The two newly-recorded caddisfly species are Diplectrona erinya, a brown insect previously only known from Tam Dao in Vietnam, and Diplectrona extrema, yellowish-brown in colour and distributed in Borneo, Sumatra, and Java.
They both belong to the genus Diplectrona, which now has 10 documented representatives in Thailand.
The researchers suggest they are probably rare in the country.
“Our study suggests that two newly reported species occur at low densities, which highlights the continuing need for efforts to conserve the [Thap Lan National] park and to conduct more studies on the caddisfly fauna,” they say in conclusion.

Nestled amongst a chain of islands in the southern reaches of Southeast Asia, Timor-Leste occupies the eastern half of the island of Timor, the largest of the Lesser Sunda Islands that also include Bali and Komodo, the latter of which is home to the Komodo Dragon. In May 2002, Timor-Leste (officially the Democratic Republic of Timor-Leste) became the first sovereign nation in the 21st century and is currently the 4th youngest country in the world.

Even though the country lies in the highly biodiverse region of Wallacea, its biodiversity is relatively poorly known, partly because decades of pre-independence violence and conflict have hindered biological surveys. In August 2022, a partnership between the Lee Kong Chian Natural History Museum (Singapore), Conservation International, and the Ministry of Agriculture and Fisheries of Timor-Leste conducted preliminary biological surveys across the eastern part of the island. The surveys specifically targeted remote and underexplored areas, such as the isolated mountain of Mundo Perdido (“Lost World” in Portuguese) and Nino Konis Santana National Park (NKS)—the first and largest national park in Timor-Leste.

NKS is an enormous park that covers 1,236 square kilometers of land and is mainly characterized by lowland tropical forests. In it, there are several limestone caves of archaeological importance, and it was in one of those caves that a new gecko species was found.
While surveying the Lene Hara cave during the day, a member of the research team caught a glimpse of a lizard scurrying on the ground before disappearing into a crevice. Dr. Chan Kin Onn, a herpetologist at the Lee Kong Chian Natural History Museum and the lead author of a study published in ZooKeys, sprung into action. Soon, he found himself wedged into a tight crevice in hopes of capturing the lizard.

“I couldn’t get to the lizard because the crack was too narrow, but I saw the rear half of its body and could tell that it was a bent-toed gecko from the genus Cyrtodactylus. New species of bent-toed geckos are being discovered all across Southeast Asia and due to the remoteness of the cave, the potential for this gecko to be a new species was high,” explained Dr. Chan.
Several hours later, under the cover of darkness, the team was back in the cave, this time equipped with flashlights. “Bent-toed geckos are usually nocturnal and can be skittish during the day. Our best chance at capturing them would be at night,” says Dr. Chan.True enough, after just one hour of looking, they collected ten specimens. A few weeks later, the gecko from Lena Hara cave was confirmed to be a new species based on DNA analysis and external morphological characteristics.

The new species is named Cyrtodactylussantana, in reference to Nino Konis Santana National Park. The park’s name honors Nino Konis Santana, a freedom fighter who led the Falintil militia against the Indonesian occupation of Timor-Leste.
Even though past surveys have documented several populations of bent-toed geckos in Timor-Leste, none of them had been identified to the species level and thus, remain unnamed. Cyrtodactylussantana is the first bent-toed gecko in Timor-Leste formally described as a species.
The expedition also discovered several interesting plants and crabs that are currently being examined, all of which have the potential to be new species. “We have barely scratched the surface of Timor-Leste’s biodiversity. New discoveries can have profound impacts, because Timor-Leste is a substantial landmass bounded by deep sea trenches and is located at the fringe of the Wallacean Biodiversity Hotspot and Weber’s Line, a transitional zone between Oriental and Australasian fauna” remarked the researchers. Understanding the biodiversity of Timor-Leste could provide key insights into the divergence, evolution, and distribution of species, they believe.

Another year rolled by and we at Pensoft have a lot to celebrate! This year, we marked our 30th birthday, and what a ride it’s been! We thank all of you for sticking around and helping us put biodiversity science in the spotlight where it deserves to be.
The holiday season is always great fun, but for us, every biodiversity or conservation win is reason enough to celebrate. And we’ve had so many this year! We already showed you our top species for the first half of 2022. Here’s an update for the second half with the most exciting new species that we’ve published across our journals:
The elusive owl from a remote island
The Principe scops-owl (Otus bikegila) was discovered on the small island of Príncipe, just off Africa’s western coast. Its existence had been suspected since 1998, but locals said its presence on the island could be traced back to 1928.
The bird is endemic to the island of Príncipe. Furthermore, the research team behind its discovery noted that it can be found only in the remaining old-growth native forest on the island, in an area that largely remains uninhabited.
8/9 The discovery and the subsequent scientific description were the result of a long process requiring the contribution of many people. It was a privilege to be a part of this. Thanks in particular to An Bollen, Barbara, Bikegila and Martim for all the help & the hard work. pic.twitter.com/ufdDlIdFXz
Otus is the generic name given to a group of small owls sharing a common history, commonly called scops-owls. They are found across Eurasia and Africa, and include such widespread species as the Eurasian scops-owl (Otus scops) and the African scops-owl (Otus senegalensis).
The species epithet “bikegila”, in turn, was chosen in homage of Ceciliano do Bom Jesus, nicknamed Bikegila – a former parrot harvester from Príncipe Island and now a park ranger on the island.The new species quickly became insanely popular, generating memes (a true sign of its popularity!). One website even described it as “a flying meme-generator that sounds like a newborn puppy.”
Nepenthes pudicais a carnivorous plant that grows prey-trapping contraptions underground, feeding off subterranean creatures such as worms, larvae and beetles.
It belongs to pitcher plants – a group of carnivorous plants with modified leaves (called pitfall traps or pitchers) that help them catch their prey.
Pitcher plants usually produce pitfall traps above ground at the surface of the soil or on trees. N. pudica is the first pitcher plant known to catch its prey underground.
At first, the researchers thought the deformed pitcher protruding from the soil that they saw had accidentally been buried. Only later, when they found additional pitcherless plants, did they consider the possibility that the pitchers might be buried in the soil.
Then, as one of the researchers was taking photos, he tore some moss off the base of a tree and found a handful of pitchers.
The unique plant, however, could already be under threat. As it only lives in one small area of Indonesia, scientists believe it should be classed as Critically Endangered.
In November 2021, biologist Alejandro Arteaga and his colleagues were traveling through the cloud forests of Ecuador looking for toads, when a local woman told them she had seen odd snakes slithering around a graveyard. Based on her description, the team suspected they might be ground snakes from the genus Atractus, which had never been scientifically recorded in that area of Ecuador.
Indeed, they were able to discover three new snake species living beneath graves and churches in remote towns in the Andes mountains.
The “small, cylindrical, and rather archaic-looking” snakes all belong to a group called ground snakes. In general, not a lot of people are familiar with ground snakes, as they usually remain hidden underground.
Sometimes life gives you lemons, and sometimes you go looking for frogs and end up finding three new species of snake! In this episode we hear from Alejandro Arteaga about his new species from the Ecuadorian Andes.https://t.co/1YjQXSNJcJpic.twitter.com/8IKJGc2sCI
All three snakes were named in honor of institutions or people supporting the exploration and conservation of remote cloud forests in the tropics. Atractus zgap, pictured here, was named in honor of theZoological Society for the Conservation of Species and Populations (ZGAP), a program seeking to conserve unknown but highly endangered species and their natural habitats throughout the world.
However, the majority of the native habitat of these new snakes has already been destroyed. As a result of the retreating forest line, the ground snakes find themselves in the need to take refuge in spaces used by humans (both dead and alive), where they usually end up being killed on sight.
Unlike some other participants in this list, this one took a while before it was confirmed as a new species: “We did not discover that it was a new species overnight,” says Oscar Lasso-Alcalá, one of the people behind its discovery.
A. mikoljii is a new species for science, but it is not a “new species” for people who already knew it locally under the name of Pavona, Vieja, or Cupaneca in Venezuela or Pavo Real, Carabazú, Mojarra and Mojarra Negra in Colombia. Nor for the aquarium trade, where it is highly appreciated and has been known by the common name of Oscar.
Moreover, the species has been of great food importance for thousands of years for at least nine indigenous ethnic groups, and for more than 500 years to the hundreds of human communities of locals who inhabit the Orinoco River basin in Venezuela and Colombia. In the plains of Orinoco, it is considered a delicacy “due to its pleasant taste and enhanced texture”.
Oscar Lasso-Alcalá has a special relationship with this fish. “It is more than just a fish in an aquarium since it is considered a true pet,” he says.
Recently, Javier Lobon-Rovira, one of the people behind the discovery of this new gecko, told us what it was like to find this exciting new species: “That night we were tired, so we decided to have a short walk around the camp. And… there it was…! Like a ghost, this small, cryptic, and elusive gecko started showing up in every big rock boulder.”
Kolekanos spinicaudusis part of Kolekanos, a unique and iconic gecko genus that is only known from southwestern Angola.
Until this discovery, Kolekanos only had one species in the genus, known only from ~200km south of the new discovery, but that species had feathers on its tail, not spines like K. spinicaudus. Immediately, the researchers knew they were dealing with a Kolekanos… but they were astonished to see the spines.
GECKO SUNDAY! Another #NewSpecies of #gecko for 2022! Meet: Kolekanos spinicaudus • A new Feather-tailed Leaf-toed Gecko, Kolekanos (Squamata: Gekkonidae) from the poorly explored Savannah of western Angola 2022. link/summary: https://t.co/TWhm0JGhcypic.twitter.com/Z8wcug7IIt
The scientific name “spinicaudus” refers to the unique appearance of the tail of this new species.
K. spinicaudus’s home in southern Angola remains poorly explored, even as it has been considered as an important source of diversification and endemism in West Africa.
“Insects in general are so diverse and so important, yet we don’t have scientific descriptions or names for so many of them,” says Dr Kit Prendergast, from the Curtin School of Molecular and Life Sciences.
The new bee species she discovered, Leioproctus zephyris excellent proof that we still have a lot to learn about bee biodiversity.
The story behind L. zephyr’s name is quite interesting – it was named after Zephyr the Maremma dog, Dr Prendergast’s fellow companion. The researcher says Zephyr played an important role in providing emotional support during her PhD. The name also references the dog-like “snout” in the bee’s anatomy that she found rather unusual.

The bee species was in fact first collected in 1979, but it had to wait until 2022 to be officially described.
However, Dr Prendergast says its future remains uncertain, as it is highly specialised, and has a very restricted, fragmented distribution.
“The Leioproctus zephyr has a highly restricted distribution, only occurring in seven locations across the southwest WA to date, and have not been collected from their original location. They were entirely absent from residential gardens and only present at five urban bushland remnants that I surveyed, where they foraged on two plant species of Jacksonia.”
Honorable mention: Two scorpion species described by high-school citizen scientists
In 2019, California teenagers Harper Forbes and Prakrit Jain were looking at entries on the naturalist social network iNaturalist, when they noticed a mysterious scorpion that a citizen scientist had encountered near a lake in theMojave Desert. The species had remained unidentified since it was uploaded six years earlier.
The entry that they were looking at was a yet undescribed scorpion species whose name they would add to the fauna of California. Shortly after, they found another entry on iNaturalist that also appeared to be an unknown scorpion species.
The new species, Paruroctonus soda and Paruroctonus conclusus, are playa scorpions, meaning they can only be found around dry lake beds, or playas, from the deserts of Central and Southern California.
This is SUCH impressive work on 2 new-to-science #Scorpion species from California, published by high school students Prakrit Jain & Harper Forbes in collaboration with @ArachnologyNerd! #Arachnology 🦂
“These kids can find anything,” Dr Esposito told The Guardian. “You set them out in a landscape and they’re like: ‘Here’s every species of snake, here’s every scorpion, every butterfly,’ and it’s kind of incredible.”
Forbes and Jain were still in high school when they made their groundbreaking discoveries. Now they are in college: Forbes at the University of Arizona studying evolutionary biology and Jain at the University of California, Berkeley, for integrative biology.
While insect populations continue to decline, taxonomic expertise in Europe is at serious risk, confirms data obtained within the European Red List of Insect Taxonomists, a recent study commissioned by the European Union.
Expertise tends to be particularly poor in the countries with the richest biodiversity, while taxonomists are predominantly male and ageing
While insect populations continue to decline, taxonomic expertise in Europe is at serious risk, confirms data obtained within the European Red List of Insect Taxonomists, a recent study commissioned by the European Union.
Scientists who specialise in the identification and discovery of insect species – also known as insect taxonomists – are declining across Europe, highlights the newly released report by CETAF, International Union for Conservation of Nature (IUCN) and Pensoft. The authors of this report represent different perspectives within biodiversity science, including natural history and research institutions, nature conservation, academia and scientific publishing.
Despite the global significance of its taxonomic collections, Europe has been losing taxonomic expertise at such a rate that, at the moment nearly half (41.4%) of the insect orders are not covered by a sufficient number of scientists. If only EU countries are counted, the number looks only slightly more positive (34.5%). Even the four largest insect orders: beetles (Coleoptera), moths and butterflies (Lepidoptera), flies (Diptera) and wasps, bees, ants and sawflies (Hymenoptera) are only adequately ‘covered’ in a fraction of the countries.
To obtain details about the number, location and productivity of insect taxonomists, the team extracted information from thousands of peer-reviewed research articles published in the last decade, queried the most important scientific databases and reached out to over fifty natural science institutions and their networks. Furthermore, a dedicated campaign reached out to individual researchers through multiple communication channels. As a result, more than 1,500 taxonomists responded by filling in a self-declaration survey to provide information about their personal and academic profile, qualification and activities.
Then, the collected information was assessed against numerical criteria to classify the scientists into categories similar to those used by the IUCN Red List of Threatened SpeciesTM. In the European List of Insect Taxonomists, these range from Eroded Capacity (equivalent to Extinct) to Adequate Capacity (equivalent to Least Concern). The assessment was applied to the 29 insect orders (i.e. beetles, moths and butterflies etc.) to figure out which insect groups the society, conservation practitioners and decision-makers need not be concerned at this point.

On a country level, the results showed that Czechia, Germany and Russia demonstrate the most adequate coverage of insect groups. Meanwhile, Albania, Azerbaijan, Belarus, Luxembourg, Latvia, Ireland and Malta turned out to be the ones with insufficient number of taxonomists.
In most cases, the availability of experts seems to correlate to GDP, as wealthiest countries tend to invest more in their scientific institutions.
What is particularly worrying is that the lack of taxonomic expertise is more evident in the countries with the greatest species diversity. This trend may cause even more significant problems in the knowledge and conservation of these species, further aggravating the situation. Thus, the report provides further evidence about a global pattern where the countries richest in biodiversity are also the ones poorest in financial and human resources.
The research team also reminds that it is European natural history museums that host the largest scientific collections – including insects – brought from all over the globe. As such, Europe is responsible to the world for maintaining taxonomic knowledge and building adequate expert capacity.
Other concerning trends revealed in the new report are that the community of taxonomists is also ageing and – especially in the older groups – male-dominated (82%).
“One reason to have fewer young taxonomists could be due to limited opportunities for professional training (…), and the fact that not all professional taxonomists provide it, as a significant number of taxonomists are employed by museums and their opportunities for interaction with university students is probably not optimal. Gender bias is very likely caused by multiple factors, including fewer opportunities for women to be exposed to taxonomic research and gain an interest, unequal offer of career opportunities and hiring decisions. A fair-playing field for all genders will be crucial to address these shortcomings and close the gap.”

The European Red List of Taxonomists concludes with practical recommendations concerning strategic, science and societal priorities, addressed to specific decision-makers.
The authors give practical examples and potential solutions in support of their call to action.
For instance, in order to develop targeted and sustainable funding mechanisms to support taxonomy, they propose the launch of regular targeted Horizon Europe calls to study important insect groups for which taxonomic capacity has been identified to be at a particularly high risk of erosion.
To address specific gaps in expertise – such as the ones reported in the publication from Romania – a country known for its rich insect diversity, yet poor in taxonomic expertise – the consortium proposes the establishment of a natural history museum or entomological research institute that is well-fitted to serve as a taxonomic facility.
Amongst the scientific recommendations, the authors propose measures to ensure better recognition of taxonomic work at a multidisciplinary level. The scientific community, including disciplines that use taxonomic research, such as molecular biology, medicine and agriculture – need to embrace universal standards and rigorous conduct for the correct citation of scientific publications by insect taxonomists.
Societal engagement is another important call. “It is pivotal to widely raise awareness of the value and impact of taxonomy and the work of taxonomists. We must motivate young generations to join the scientific community” points Prof. Lyubomir Penev, Managing Director of Pensoft.

“Understanding taxonomy is a key to understanding the extinction risk of species. If we strategically target the gaps in expert capacity that this European Red List identifies, we can better protect biodiversity and support the well-being and livelihoods of our societies. With the climate crisis at hand, there is no time left to waste,”
added David Allen from the IUCN Red List team.
“As a dedicated supporter of the IUCN Red List, I am inspired by this call to strengthen the capacity, guided by evidence and proven scientific methods. However, Europe has much more scientific capacity than most biodiversity-rich regions of the world. So, what this report particularly highlights is the need for massively increasing investment in scientific discovery, and building taxonomic expertise, around the world,”
said Jon Paul Rodríguez, Chair of the IUCN Species Survival Commission.
