Conferences across the continents: Pensoft’s events in Autumn 2023

Pensoft participated in several events all around the world in October and November 2023.

October and November 2023 were active months for the Pensoft team, who represented the publisher’s journals and projects at conferences in Europe, North America, South America, Oceania and Asia.

Let’s take a look back at all the events of the past two months.

The Biodiversity Information Standards Conference 2023

The Biodiversity Information Standards (TDWG) Conference, held from October 9-13 in Tasmania, Australia, brought together experts and stakeholders from the global biodiversity research community.

The annual gathering is a crucial platform for sharing insights, innovations, and knowledge related to biodiversity data standards and practices. Key figures from Pensoft took part in the event, presenting new ways to improve the management, accessibility, and usability of biodiversity data. 

Prof. Lyubomir Penev, founder and Chief Executive Officer of Pensoft, gave two talks that highlighted the importance of data publishing. His presentation on “The Biodiversity Knowledge Hub (BKH): A Crosspoint and Knowledge Broker for FAIR and Linked Biodiversity Data” underscored the significance of FAIR (Findable, Accessible, Interoperable, and Reusable) data standards. BKH is the major output from the Horizon 2020 project BiCIKL (Biodiversity Community Integrated Knowledge Library) dedicated to linked and FAIR data in biodiversity, and coordinated by Pensoft.

Many authors and editors at Biodiversity Data Journal also spoke at the TDWG conference, including Vince Smith, the journal’s editor-in-chief, who is Head of Digital, Data, and Informatics at the Natural History Museum. He delivered insightful presentations on digitising natural science collections and utilising AI for insect collections.

GEO BON Global Conference 2023

GEO BON’s Global Conference on Biodiversity and Monitoring took place from 10-13 October 2023 in Montreal, Canada.

Metabarcoding and Metagenomics editor-in-chief, Florian Leese.

The theme of the conference was “Monitoring Biodiversity for Action” and there was particular emphasis on the development of best practices and new technologies for biodiversity observations and monitoring to support transformative policy and conservation action.

Metabarcoding & Metagenomics’ editor-in-chief, Florian Leese, was one of the organisers of the “Standardized eDNA-Based Biodiversity Monitoring to Inform Environmental Stewardship Programs” session. Furthermore, the journal was represented at Pensoft’s exhibition booth, where conference participants were able to discuss metabarcoding and metagenomics research.

Following the conference, Metabarcoding & Metagenomics announced a new special issue titled “Towards Standardized Molecular Biodiversity Monitoring.” The special issue is accepting submissions until 15th March 2024.

Asian Mycological Congress 2023

Mysterious new moth species discovered in Europe

The moth, named Mirlatia arcuata, by a research team from Germany, Austria, and the United Kingdom, is one of the most remarkable discoveries in Lepidoptera of recent decades.

European Lepidoptera (butterflies and moths), with a currently known inventory of approximately 11, 000 species, are generally considered well-researched. However, a new genus and species from the Geometrid moth family described in the scientific journal ZooKeys tell a different story. The moth, named Mirlatia arcuata by a research team from Germany, Austria, and the United Kingdom, is one of the most remarkable discoveries in Lepidoptera of recent decades.

Decades-old UFO

In the early 1980s, Austrian amateur entomologist Robert Hentscholek collected three specimens of a moth species in southern Dalmatia, Croatia, which were integrated into his collection or given to colleagues without being identified. Decades later, the collection was sold to Toni Mayr, another hobbyist researcher from Austria, who immediately noticed the unusual insect that stood out from all known European species and couldn’t even be assigned to a known genus.

An adult female of Mirlatia arcuata.

The collector was contacted to provide more information, and it turned out that a male and a female specimen of the same species had been given to another collector who had since passed away. The female specimen was rediscovered in 2015 in the collection of the Natural History Museum in Vienna, while the whereabouts of the other specimen remained unknown. The unique male was finally presented to the Tyrolean Federal State Museums by Toni Mayr.

In 2022, a research team was formed to identify this enigmatic moth, and it was finally described as a new genus and species in early November 2023. It was given the name Mirlatia arcuata, where Mirlatia is an aggregate of the stems of two Latin words that translate loosely as “bringing a surprise,” a reference to the surprising discovery of this curious new moth.

Cold-adapted or introduced?

The discovery of such a large and distinctive moth species in a well-explored region like southern Croatia might seem unlikely. However, according to researcher Peter Huemer of the Tyrolean State Museums (Ferdinandeum), who took part in the study, there was surprisingly little research conducted in that area during the moth’s flight season in March. “It’s possible that Mirlatia arcuata is a cold-adapted, winter-active species that would need to be sought in the middle of winter,” he says.

The hypothesis of introduction from other continents was discarded by the study authors for several reasons. Axel Hausmann from the Zoological State Collection in Munich examined all known moths from cold regions in the northern and southern hemisphere and could not identify a similar species from these regions. Furthermore, the collecting location in Podgora is not in close proximity to a port, and during the Yugoslavian era, the traffic in Dalmatian ports was rather limited. Also, Split and other Croatian ports were rarely visited by ships from other continents during the communist period. Additionally, Robert Hentscholek had never collected in the tropics, ruling out the possibility of a labeling error.

Many questions, few answers

Despite all efforts, the relationships of the new genus and species have not been definitively clarified. Even the assignment to the subfamily Larentiinae is not entirely secure and is based on a few features like wing venation. Initial genetic data from the mitochondrial COI barcode, as well as characteristics of the tympanal organ (auditory organ), point to a largely independent systematic position of the species. Further investigations of the entire genome could provide more clarity.

Even less is known about the biology of the new species, apart from the fact that its known habitat consists of coastal rock biotopes with Mediterranean vegetation. In March 2022, Slovenian lepidopterologist Stane Gomboc initiated a comprehensive search, but it turned out to be unsuccessful. It’s possible that the moth’s flight season has already ended due to climate warming.

The study authors hope they will soon rediscover Mirlatia arcuata and know more about its habitat requirements and biology.

A decade of empowering biodiversity science: celebrating 10 years of Biodiversity Data Journal

Together, we have redefined scientific communication, and we will continue to push the boundaries of knowledge.

Today, 16 September 2023, we are celebrating our tenth anniversary: an important milestone that has prompted us to reflect on the incredible journey that Biodiversity Data Journal (BDJ) has been through.

From the very beginning, our mission was clear: to revolutionise the way biodiversity data is shared, accessed, and harnessed. This journey has been one of innovation, collaboration, and a relentless commitment to making biodiversity data FAIR – Findable, Accessible, Interoperable, and Reusable.

Over the past 10 years, BDJ, under the auspices of our esteemed publisher Pensoft, has emerged as a trailblazing force in biodiversity science. Our open-access platform has empowered researchers from around the world to publish comprehensive papers that seamlessly blend text with morphological descriptions, occurrences, data tables, and more. This holistic approach has enriched the depth of research articles and contributed to the creation of an interconnected web of biodiversity information.

In addition, by utilising ARPHA Writing Tool and ARPHA Platform as our entirely online manuscript authoring and submission interface, we have simplified the integration of structured data and narrative, reinforcing our commitment to simplifying the research process.

One of our most significant achievements is democratising access to biodiversity data. By dismantling access barriers, we have catalysed the emergence of novel research directions, equipping scientists with the tools to combat critical global challenges such as biodiversity loss, habitat degradation, and climate fluctuations.

We firmly believe that data should be openly accessible to all, fostering collaboration and accelerating scientific discovery. By upholding the FAIR principles, we ensure that the datasets accompanying our articles are not only discoverable and accessible, but also easy to integrate and reusable across diverse fields.

As we reflect on the past decade, we are invigorated by the boundless prospects on the horizon. We will continue working on to steer the global research community towards a future where biodiversity data is open, accessible, and harnessed to tackle global challenges.

Ten years of biodiversity research

To celebrate our anniversary, we have curated some of our most interesting and memorable BDJ studies from the past decade.

  • Recently, news outlets were quick to cover a new species of ‘snug’ published in our journal.

  • Who could forget this tiny fly named after the former Governor of California?
  • Or this snail named after climate activist Greta Thunberg?
Craspedotropis gretathunbergae

New discoveries are always exciting, but some of our favourite research focuses on formerly lost species, back where they belong.

  • Like the griffon vulture, successfully reintroduced to Bulgaria after fifty years.

Citizen science has shown time and time again that it holds an important position in biodiversity research.

  • This group, for example, who found a beetle the size of a pinhead in Borneo.

New grasshopper species from central Texas honor Willie Nelson and Jerry Jeff Walker

These findings highlight the rich biodiversity of the region, emphasizing the importance of conservation efforts in the area.

The central region of Texas is a known hotspot of biological wonders. For the last five years, Dr. JoVonn Hill, an Assistant Professor and Director of the Mississippi Entomological Museum (MEM) at Mississippi State University, and his colleagues have made scientific expeditions to the area that have now revealed an extraordinary find.

The team uncovered seven previously unknown flightless grasshopper species, six of them endemic to the Edwards Plateau, which underscores the region’s extraordinary biodiversity.

With this discovery, Dr. Hill is paying tribute to two iconic musicians. In recognition of the “immense contributions” of Texas legends Willie Nelson and Jerry Jeff Walker, he has named two of these flightless grasshopper species after them.

“Melanoplus nelsoni and Melanoplus walkeri immortalize the enduring contributions of these legendary musicians and their connection to Texas,” he says.

Melanoplus walkeri.

“After these last few summers [of field studies], just like Mr. Nelson, we too have a little Texas in our souls,” he writes in his study, which was just published in the journal ZooKeys.

On Melanoplus walkeri, he writes: “Walker’s songs such as Hill Country Rain, Leavin’ Texas, and Sangria Wine brought me and my field team joy while traveling between field sites and added to the amazing ambiance of the Edwards Plateau.” In fact, the artist recorded his most influential album not far away from the spot where the new species was discovered.

Additionally, the team acknowledges the cultural heritage and deep connection to the region of the Comanche and Tonkawa tribes, naming two species after them, Melanoplus commanche and Melanoplus tonkawa respectively.

“These designations recognize the profound historical and cultural significance of the tribes in the region,” Dr. Hill explains.

Melanoplus tonkawa.

“These seven newly described species, alongside two preexisting ones, form a cohesive species group, highlighting their shared characteristics and evolutionary relationships,” Dr. Hill says in conclusion. “The formation of this new species group presents a significant contribution to our understanding of the diverse ecosystems present in central Texas,” he adds.

The discovery of these seven flightless grasshopper species and the formation of a new species group underscore the ecological uniqueness of central Texas, Dr. Hill says. He and the staff of the Mississippi Entomological Museum remain committed to scientific exploration and understanding, promoting the conservation of biodiversity, and inspiring a sense of wonder and appreciation for the natural world.

New African Invertebrates issue celebrates the work of Dr Jason G. H. Londt

For more than 50 years, Londt has made a notable impact on South African and international entomology.

The latest issue published in African Invertebrates is a special one: it honours the career and achievements of South African entomologist Dr Jason G. H. Londt. In celebration of Londt’s prolific and inspiring work, the issue was published to coincide with his 80th birthday in 2023.

For more than 50 years, Londt has made a notable impact on South African and international entomology, collecting large numbers of Diptera and other insect orders. He has made outstanding contributions to the entomological research on flies, especially assassin or robber flies (Diptera, Asilidae), on hangingflies (Mecoptera, Bittacidae), and field collections of insects, primarily in South Africa.

Throughout his career, he has described more species of Afrotropical Asilidae and Bittacidae (Mecoptera) than any other author.

“Today, some 952 Asilidae species are recognised from southern Africa and thanks to Jason’s exceptional collecting efforts and detailed revisionary taxonomic publications these species can be easily identified,“ write African Invertebrates editors John Midgley and Torsten Dikow in the editorial to the Festschrift.

The Festschrift includes nine articles celebrating Dr Londt’s career by authors from three continents, covering the broad contributions that he has made to Afrotropical entomology. It also introduces five new species described in his honour, one hangingfly and four true flies.

The amazing diversity of the Caribbean pygmy jumping leaves

Pygmy grasshoppers come in many shapes and colors and are often exciting to see, but their taxonomy is a mess.

Guest blog post by Josip Skejo & Niko Kasalo

A lovable mess

Tetrigidae, commonly known as pygmy grasshoppers, are an ancient and diverse family, currently numbering about 2000 species. As their name suggests, tetrigids are very small; their largest representatives are barely several centimeters long, so they might be difficult to spot on a casual stroll through tropical vegetation. However, when they are spotted, they are immediately recognizable by their elongated pronotum, a hard structure that starts behind the head and covers the entire body like a hood. They come in many shapes and colors and are often exciting to see, but this comes with a price—the taxonomy of Tetrigidae, the way they are organized into natural groups, is a mess. This is where we come in.

The mini grasshoppers that outlived dinosaurs: the fascinating world of Tetrigidae

In our latest paper, we dealt with Choriphyllini, a small Caribbean tribe that belongs to the subfamily Cladonotinae. This subfamily had been filling up with unrelated but similar-looking tetrigids for more than a century. It had never been clearly defined so almost everything wingless and robust was assigned to Cladonotinae. We decided to put an end to this by slowly removing the superficially similar genera from the subfamily and describing tribes to group the genera that are clearly related to each other. We piloted this system just last year, when we described the tribe Valalyllini from Madagascar, with only two endemic (and endangered) genera and species.

The diversity and the distribution of the tribe Valalyllini, the Malagasy dead-leaf-like Cladonotinae. Both species are endemic to small areas and are likely endangered because of deforestation. Both species most probably inhabit rainforest leaf litter.

Put the species of Choriphyllini and Valalyllini together, mix them up, and try to guess which belongs where—this is no simple task; they are all doing their impressions of dead leaves that our primate brains struggle to differentiate. And there’s more: such leaf-like grasshoppers live in Africa and South East Asia as well, and then there are those that look like twigs and spiky tree bark.

Only now that we have an idea of what the true Cladonotinae are can we be properly amazed by the duality they represent to us. On the one hand, they are incredibly diverse with every species having its own variation on the basic shape. On the other, they are so alike that they either represent the best example of convergent evolution ever documented or they all stem from a common ancestor that is currently supposed to have lived during the Mesozoic. The evolutionary history of Cladonotinae will take many years to unravel, but the work can only begin after we define what to call by that name.

Valalyllum folium, a member of the tribe Valalyllini, subfamily Cladonotinae. This species, endemic to Madagascar, is a relative of Choriphyllini.

It only took 250 years

The first species of Choriphyllini, Phyllotettix rhombeus, was described in 1765 as Cicada rhombea, that is, as a member of an entirely different order of insects. Continuing in this manner, many authors (including the great Linnaeus himself) made many taxonomic and nomenclatural mistakes that compounded over the centuries and made these grasshoppers difficult to identify and refer to. It didn’t help that new species and new records kept being reported without being contextualized by comprehensive literature reviews. Like detectives, we followed the scattered crumbs of data and arrived at a synthesis that will make future research in the region much more pleasant.

Hancock’s plate I from the “Tettigidae of North America” shows leaf-like Caribbean species under the numbers 1), 2) and 7), but has many taxonomic and nomenclatural errors. 1) – Phyllotettix foliatus (= female holotype of Hancock’s Choriphyllum foliatum), 2) – Phyllotettix rhombeus (= Hancock’s Choriphyllum westwoodi), 7) – Choriphyllum saussurei. (= Hancock’s Phyllonotus saussurei). Source: Biodiversity Heritage Library, available at https://www.biodiversitylibrary.org/item/25899#page/10.

This is not where interesting facts about Phyllotettix rhombeus stop. While looking through the literature, we tried to extract the measurements of drawings. Most of the drawings had a scale bar printed next to them, but the archaic usage of “lines” as the standard measurement initially gave us some trouble. That is why at first we doubted one of our most fascinating discoveries: with the pronotal length measuring nearly 3 centimeters, Phyllotettix rhombeus is the largest tetrigid ever recorded! Many, many authors dealt with this species over the last 250 years, but this record was never made explicit.

It should not go unnoticed now that its proposed common name is “Jamaican Colossal Jumping Leaf”. Inspired by this, we took the measurements of the other species as well and made a figure where all the specimens are resized to a common scale, which shows the diversity of both shapes and sizes.

The genera and species of the tribe Choriphyllini. All specimens are drawn to scale.

Besides P. rhombeus, there are three more species in the genus Phyllotettix: P. plagiatus, P. foliatus, and P. compressus. All four of them are known only from Jamaica. P. foliatus and P. compressus are known from the Blue Mountains, but for the other two no precise localities are known; we still don’t know where exactly the largest tetrigid lives. The other genus of the tribe is Choriphyllum, also with four species. Three of them, C. sagrai, C. saussurei, and C. wallaceum live in Cuba, while C. bahamense is all alone on Hummingbird Cay island in the Bahamas. The easiest way to differentiate these two genera is a little strange but practical, the tallest point of the leaf-like crest in Choriphyllum species is in the front, while in Phyllotettix species it is in the back.

A map of all known Choriphyllini records. For three species, not a single precise locality is known.

Some Caribbean leaves dance and jump

For each species, we proposed a common name as a means to give these animals even more character. Names, such as “Jamaican Bitten Jumping Leaf” and “Old Cuban Dancing Leaf” may not be “official”, but they have certainly found their audience. The tweet in which we shared the collage of all the species was viewed over 17000 times; everyone was amazed by the pretty shapes and some even noted that they especially liked the crazy common names. We were very glad to see our scientific and artistic package that is Choriphyllini be so warmly received.

Another hit on Twitter, with over 20000 views, is the post showcasing the newly-described species from Cuba, Choriphyllum wallaceum. The holotype of this species has been awaiting description for a long time. We found it in Museo Nacional de Ciencias Naturales in Madrid, Spain, with a note from Ignacio Bolívar, the father of the Tetrigidae classification system. He referred to it as “Choriphyllum Seoanei” but never managed to publish it.

This “new” species presented us with the perfect opportunity to honor the 200th anniversary of Alfred Russel Wallace’s birth. Wallace is often called the “father of biogeography” but is all too often neglected when discussing the origins of the theory of evolution, with which Charles Darwin is considered synonymous. Wallace, with his independent arrival at the key concepts of the evolutionary theory, his correspondence with Darwin, and his staunch defense of Darwin’s ideas, was (and is) at the very least equal to Darwin and deserves much more recognition than he currently gets.

Choriphyllum wallaceum, a newly-described species from Cuba, named after Alfred Russel Wallace.

This is just the start

Choriphyllini are a pretty package, but one that merely introduces the real problem. The history of this tribe is long, yet we have very few specimens to work with. Although we have an understanding of how morphology varies within species, P. compressus and P. foliatus are not only suspiciously similar to each other, but they also live in the same general area of the Blue Mountains. It remains to be seen if they are in fact a single species.

Much more pressing is that we have only a vague idea of where these animals live and how their populations are impacted by various factors such as human activity and climate change—we do not have a baseline against which to assess their conservation status. Then there is the fact that there are many more islands in the Caribbean, making the possibility of discovering new Choriphyllini species on them real and exciting. We can only guess what the future holds for these neglected animals.

The stage is set; everything we know about this group is laid out in the paper and now there is no path but forward. Research is expensive, dedication to this work takes a certain kind of soul, and everything takes time. It is our sincere hope that someone someday takes this further. The pygmy jumping leaves will wait for as long as they can, on their islands, hopping without a care in the world.

Interoperable biodiversity data extracted from literature through open-ended queries

OpenBiodiv is a biodiversity database containing knowledge extracted from scientific literature, built as an Open Biodiversity Knowledge Management System. 

The OpenBiodiv contribution to BiCIKL

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,”

concludes Prof Lyubomir Penev.

Where did all those insects come from? Tracking the history of insect invasion in Chile

Going through centuries-old literature, researchers compiled a database of the exotic insects established in the country.

Guest blog post by Daniela N. López, Eduardo Fuentes-Contreras, Cecilia Ruiz, Sandra Ide, Sergio A. Estay

Understanding the history of non-native species arrivals to a country can shed light on the origins, pathways of introduction, and the current and future impacts of these species in a new territory. In this sense, collecting this information is important, and sometimes essential, for researchers and decision makers. However, in most cases, reconstructing this history takes a lot of work. Finding antique references is hard work. To add more complexities, changes in the taxonomy of species or groups could be frustrating as we try to track the moment when a species was referenced in the country for the first time, sometimes centuries ago. Of course, we only learned about these issues when, almost seven years ago, we thought that compiling a database for the exotic insects established in Chile would be interesting to people working on invasive species in the country.

First, we collected information from physical and electronic books and journals available in our institutional libraries, but soon we noticed that we needed a more significant effort. In Chile, the National Library and The National Congress library allowed us to review and collect information from texts, in many cases, over a hundred years old. We also had to request information from foreign specialized libraries and bookstores. Sometimes, we had to negotiate with private collectors to buy antique books or documents. When we figured the first version of the database was ready, we began a second step for detecting errors, correcting the taxonomy, and completing the information about the reported species.

The analysis began when we finally completed the database. What types of questions could we answer using this data? Was the database complete enough to detect historical, biogeographic, and ecological patterns? Two competing hypotheses were the starting point for the study at this stage. On the one hand, the species that dominated the non-native insect assemblage could have come from original environmental conditions that matched Chile’s. Or, the pool of non-native insects arrived using pathways associated with the country’s economic activities, regardless of their origin.

We found records of almost 600 non-native insect species established in continental Chile. Most species corresponded to Hemiptera (true bugs and scales, among others) from Palaearctic origin and were linked to agriculture and forestry, as we initially hypothesized. These characteristics point to the central role of intercontinental human-mediated transport in structuring non-native insect assemblages in Chile. Non-native insect introductions began immediately after the arrival of Europeans to the central valley of Chile and have shown an enormous acceleration since 1950. Using data on the economic history of Chile, we can preliminary link this acceleration with the strong development in agriculture and forestry in Chile after World War II and the increase in intercontinental air traffic.

The development and analysis of this database gave us some preliminary answers about the ecology of invasive insect species and opened the door to new questions. Also, this is a work in progress. We need the scientific community’s support to improve and correct the records, provide new reports and collect further references to support the database. Our data and analysis may be representative of other countries in South America. Similarities between our countries can facilitate using this information to manage recent introductions and prevent significant economic, social, or environmental damage.

Two newly recorded species join Thailand’s aquatic insect fauna

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.

Experts in insect taxonomy “threatened by extinction” reveals the first European Red List of Taxonomists

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.
