The scientific name and English-language common name acknowledge the importance of maintaining equitable and safe access to outdoor spaces for all people.

A new species of Australian bush tomato described from the Garrarnawun Lookout in Judbarra National Park provides a compelling example of the need to provide equal and safe access to natural places. Bucknell University postdoctoral fellow Tanisha Williams and biology professor Chris Martine led the study following a chance encounter with an unusual population of plants during a 2019 research expedition to the Northern Territory.
Martine, who has studied northern Australia’s bush tomatoes for more than 20 years, immediately sensed that the plants were representative of a not-yet-described species, so he, Angela McDonnell (St. Cloud State University), Jason Cantley (San Francisco State University), and Peter Jobson (Northern Territory Herbarium in Alice Springs) combed the local area for plants to closely study and make research collections from. The task was made easier by the fact that the Garrarnawun Lookout is accessible by a set of dozens of human-made stone steps running directly from the unpaved parking area to the peak of the sandstone outcrop – without which the new species might have otherwise gone unnoticed.
The botanists were able to collect numerous new specimens and have now published the new species description in the open-access journal PhytoKeys, choosing the name Solanum scalarium as a nod to the steps leading to the plant and the unusual ladder-like prickles that adorn the flowering stems. The Latin “scalarium” translates to “ladder”, “staircase” or “stairs.”

Tanisha Williams and Chris Martine. Photo by J. Hayes
“This Latin name does relate to the appearance of this species, how it looks,” says first-author Williams. “But it is also a way for us to acknowledge how important it is to create ways for people to interact with nature; not just scientists like us, but everyone.”

According to the authors, a recent study done by the Department of Local Government, Sport and Cultural Industries in Western Australia found that 8 in 10 people felt it is important to have access to natural spaces, both locally and outside of their current jurisdictions. However, one in three persons felt dissatisfied with the current outdoor spaces available to them and many identified barriers to access and participation in outdoor activities that include urbanization – which is especially credited for the growing number of Australians that lack outdoor experiences.
Importantly, the awareness of who has access and feels safe to participate in outdoor activities is being recognized throughout Australia and the lack of diversity in participation from culturally diverse and marginalized populations has been identified as an issue. Key indices such as ethnic background, socio-economic status, physical abilities and gender, are indicators of low outdoor recreation participation.
“These disparities of who are and are not participating and who feels safe and welcomed are artifacts of historic and current environmental and social injustices,” notes Williams. “To overcome these injustices and increase access and participation from diverse groups, intentional and targeted efforts are needed to provide a range of outdoor experiences that attract people from all of the 270 plus ancestries with which Australians identify with and special attention should be placed on groups historically excluded from outdoor spaces.”

Also now known as the Garrarnawun Bush Tomato, Solanum scalarium is a distant cousin of the cultivated eggplant and a close relative to a number of other Australian species recently discovered by Martine and colleagues that were also published in PhytoKeys including Solanum plastisexum, named to reflect the diversity of sex forms across Earth’s organisms; and Solanum watneyi, named for the space botanist of the book/film The Martian.
The scientists hope that the naming of this latest new species highlights the importance of building community around natural spaces.

“We suggest the use of Garrarnawun Bush Tomato for the English-language common name of the species,” the authors write, “In recognition of the Garrarnawun Lookout near where the type collection was made, a traditional meeting place of the Wardaman and Nungali-Ngaliwurru peoples whose lands overlap in this area.”
Access to nature is not just a concern in Australia.
“In the United States, where most of the authors of this paper are located, “access” is one thing but safety and equitability are another,” says Martine, “The U.S. National Parks Service reports that around 95% of those who visit federal parks are white. Meanwhile, African Americans, Latinos, women, and members of the LGBTQIA+ communities often report feeling unwelcome or unsafe in outdoor spaces.”
“If African Americans, for example, are already apprehensive in a country where they make up 13% of the population, it should be understandable that they are hesitant to be part of a community where they represent as little as 1% of participants.”

Williams suggests that James Edward Mills, author of The Adventure Gap (2014) put it best:
“It’s not enough to say that the outdoors is free and open for everyone to enjoy. Of course it is! But after four centuries of racial oppression and discrimination that systematically made Black Americans fear for their physical safety, we must also make sure that we create a natural environment where people of color can not only feel welcome but encouraged to become active participants as outdoor enthusiasts and stewards dedicated to the protection of the land.”
Recent Bucknell graduate Jonathan Hayes, who measured and analyzed the physical characters of the new species using plants grown from seed in a campus greenhouse, joins Williams, McDonnell, Cantley, Jobson, and Martine as a co-author on the publication.

All journals published by Pensoft – each using the publisher’s self-developed ARPHA Platform – provide extensive and transparent information about their costs and services in line with the Plan S principles.
In support of transparency and openness in scholarly publishing and academia, the scientific publisher and technology provider Pensoft joined the Journal Comparison Service (JCS) initiative by cOAlition S, an alliance of national funders and charitable bodies working to increase the volume of free-to-read research.
As a result, all journals published by Pensoft – each using the publisher’s self-developed ARPHA Platform – provide extensive and transparent information about their costs and services in line with the Plan S principles.
The JCS was launched to aid libraries and library consortia – the ones negotiating and participating in Open Access agreements with publishers – by providing them with everything they need to know in order to determine whether the prices charged by a certain journal are fair and corresponding to the quality of the service.
According to cOAlition S, an increasing number of libraries and library consortia from Europe, Africa, North America, and Australia have registered with the JCS over the past year since the launch of the portal in September 2021.
While access to the JCS is only open to librarians, individual researchers may also make use of the data provided by the participating publishers and their journals.
This is possible through an integration with the Journal Checker Tool, where researchers can simply enter the name of the journal of interest, their funder and affiliation (if applicable) to check whether the scholarly outlet complies with the Open Access policy of the author’s funder. A full list of all academic titles that provide data to the JCS is also publicly available. By being on the list means a journal and its publisher do not only support cOAlition S, but they also demonstrate that they stand for openness and transparency in scholarly publishing.
“We are delighted that Pensoft, along with a number of other publishers, have shared their price and service data through the Journal Comparison Service. Not only are such publishers demonstrating their commitment to open business models and cultures but are also helping to build understanding and trust within the research community.”
said Robert Kiley, Head of Strategy at cOAlition S.

Which one is the species that springs to mind when you think about the most awesome discoveries in recent times?
In an age where we more than ever need to appreciate and preserve the magnificent biodiversity inhabiting the Earth, we decided to go for a lighter and fun take on the work of taxonomists that often goes unnoticed by the public.
From the ocean depths surrounding Indonesia to the foliage of the native forests of Príncipe Island and into the soils of Borneo, we started with 16 species described as new to science in journals published by Pensoft over the years.
Out of these most amazing creatures, over the past several weeks we sought to find who’s got the greatest fandom by holding a poll on Twitter (you can follow it further down here or via #NewSpeciesShowdown).
Grand Finale – here comes the champion!
Truly, we couldn’t have a more epic final!
The two competitors come from two kingdoms, two opposite sides of the globe, and the “pages” of two journals, namely PhytoKeys and Evolutionary Systematics.
While we need to admit that we ourselves expected to crown an animal as the crowd-favourite, we take the opportunity to congratulate the botanists amongst our fans for the well-deserved win of Nepenthes pudica (see the species description)!
Find more about the curious one-of-a-kind pitcher plant in this blog post, where we announced its discovery following the new species description in PhytoKeys in June 2022:
Back then, N. pudica gave a good sign about its worldwide web appeal, when it broke the all-time record for online popularity in a competition with all plant species described in PhytoKeys over the journal’s 22-year history of taxonomic papers comrpising over 200 issues.
What’s perhaps even more curious, is that there is only one species EVER described in a Pensoft-published journal that has so far triggered more tweets than the pitcher plant, and that species is the animal that has ended up in second place in the New Species Showdown: a tiny amphibian living in Peru, commonly known as the the Amazon Tapir Frog (Synapturanus danta).Which brings us once again to the influence of botanists in taxonomic research.
Read more about its discovery in the blog post from February 2022:
Another thing that struck us during the tournament was that there was only one species described in our flagship journal in systematic journal ZooKeys: the supergiant isopod Bathynomus raksasa, that managed to fight its way to the semi-finals, where it lost against S. danta.
This makes us especially proud with our diverse and competitive journal portfolio full of titles dedicated to biodiversity and taxonomic research!
The rules
Twice a week, @Pensoft would announce a match between two competing species on Twitter using the hashtag #NewSpeciesShowdown, where everyone could vote in the poll for their favourie.
Disclaimer
This competition is for entertainment purposes only. As it was tremendously tough to narrow the list down to only sixteen species, we admit that we left out a lot of spectacular creatures.
To ensure fairness and transparency, we made the selection based on the yearly Altmetric data, which covers articles in our journals published from 2010 onwards and ranks the publications according to their online mentions from across the Web, including news media, blogs and social networks.
We did our best to diversify the list as much as possible in terms of taxonomic groups. However, due to the visual-centric nature of social media, we gave preference to immediately attractive species.
The first tie of the New Species Showdown was between the olinguito: Bassaricyon neblina (see species description) and the “snow-coated” tussock moth Ivela yini (see species description).
In the second battle, we faced two marine species discovered in the Indian Ocean and described in ZooKeys. The supergiant isopod B. raksasa (see species description) won against the Rose Fariy Wrasse C. finifenmaa (see species description) with strong 75%.
✨Tapir “chocolate” frog S. danta claims the #NewSpeciesShowdown victory against the transparent Glass frog H. yaku by 73%! 🙌Congrats to all who voted for the tiny but very pretty frog which was described only this year in @EvolSystematics! pic.twitter.com/kAFrmepyJa
In the third battle, we faced two frog species: the tapir ‘chocolate’ frog described in Evolutionary Systematics (see species description) winning against the ‘glass frog’ described in Zookeys (see species description) with 73%.
With 62% of the votes, the two-species tournament saw the Harryplax severus crab grab the win against another species named after a great wizard from the Harry Potter universe: the Salazar’s pit viper, which was described in the journal Zoosystematics and Evolution in 2020. The “unusual” crustacean was described back in 2017 in ZooKeys. As its species characters matched no genus known to date, the species also established the Harryplax genus.
Earlier this year, the 1st #plant to grow underground pitcher was described in @PhytoKeys & quickly became the most tweeted paper EVER published in our #botany#journal! So, it isn't too hard to see how it won with 68% against the Demon's orchid in this #NewSpeciesShowdown!🔝 1/3 pic.twitter.com/toC6epfVus
With the fifth battle in the New Species Showdown taking us to the Kingdom of Plants, we enjoyed a great battle between the first pitcher plant found to grow its pitchers underground to dine (see the full study) and the Demon’s orchid, described in 2016 from a single population spread across a dwarf montane forest in southern Colombia (read the study). Both species made the headlines across the news media around the world following their descriptions in our flagship botany journal PhytoKeys.
Next, we saw the primitive dipluran Haplocampa wagnelli (read its species description in Subterranean Biology) – a likely survivor of the Ice Age thanks to the caves of Canada – win the public in a duel against Xuedytes bellus (described in ZooKeys in 2017), also known as the Most cave-adapted trechine beetle in the world!
We had a close battle between the Principe Scops-owl Otus bikegila (see species description published in our ZooKeys earlier in 2022) and the blue-tailed Monitor lizard Varanus semotus (also first ‘known’ from the pages of ZooKeys, 2016). Being adorable species, but also ‘castaways’ on isolated islands in the Atlantic, they made great sensations upon their discovery.In fact, the reptile won with a single vote!
In the last battle of Round 1, the ‘horned’ tarantula C. attonitifer claimed the victory with a strong (80%) advantage from its competitor with a rebel name: the freshwater crayfish C. snowden (species description in ZooKeys from 2015). Described in African Invertebrates in 2019, the arachnid might be one amongst many ‘horned’ baboon spiders, yet there was something quite extraordinary about its odd protuberance. Furthermore, it came to demonstrate how little we know about the fauna of Angola: a largely underexplored country located at the intersection of several ecoregions.
In the first quarter-final round, in the close battle, the isopod ’emerged’ from the ocean depths of Indonesia B. raksasa (species description in Zookeys from 2020) claimed the victory with just a few votes difference (58%!) from its competitor: lovely olinguito B. neblina, also described in Zookeys but back in 2013.
After a challenging round, the ‘chocolate’ Tapir #frog S. danta (discovery published in @EvolSystematics) makes it to the semi-final leaving its competitor #crab Harryplax severus behind!
In the second round of the quarter-final, the tapir ‘chocolate’ frog S. danta (described in Evolutionary Systematics this year) claimed the victory with a significant advantage (69%) over its competitor crab H. severus described in Zookeys in 2017.
The third battle in Round 2 secured a place at the semi-finals for the only plant to get this far in the New Species Showdown. If you are dedicated to the mission of proving the plant kingdom superior: keep supporting Nepenthes pudica in the semi-finals and beyond! In the meantime, read the full description of the species, published in our PhytoKeys in June.
The last quarter-final send the Angolan ‘horned’ tarantula to the next round. Described in African Invertebrates in 2019, its discovery would have likely remained a secret had it not been for the local tribes who provided the research team with crucial information about the curious arachnid.
Curiously enough, by winning against the ‘supergiant’ isopod B. raksasa – also known around the Internet as the ‘Darth Vader of the seas’ – the Amazonian anuran S. danta outcompetes the last species in the New Species Showdown representing our flagship taxonomy journal: ZooKeys.
In a dramatic turn of events, the tight match between the Angolan tarantula C. attonitifer , whose ‘horn’ protruding from its back surprised the scientists because of its unique structure and soft texture, and the first pitcher plant whose ‘traps’ can be found underground in Borneo, ended up with the news that the New Species Showdown will be concluding with a battle between the kingdoms Animalia and Plantae! What a denouement!
If you have gone to the Pensoft website at any point in 2022, visited our booth at a conference, or received a newsletter from any of our journals, by this time, you must be well aware that in 2022 – more precisely, on 25 December – we turned 30. And we weren’t afraid to show it!
Pensoft’s team happy to showcase the 30-year story of the company at various events this year. Left: Maria Kolesnikova at the annual Biodiversity Information Standards (TDWG 2022) conference, hosted by Pensoft in Sofia, Bulgaria. Right: Iva Boyadzhieva at the XXVI International Congress of Entomology (ICE 2022) in Helsinki, Finland.
Indeed, 30 is not that big of a number, as many of us adult humans can confirm. Yet, we take pride in reminiscing about what we’ve done over the last three decades.
The truth is, 30 years ago, we wouldn’t have been able to picture this day, let alone think that we’d be sharing it with all of you: our journal readers, authors, editors and reviewers, collaborators in innovation, project partners, and advisors.
Long story short, we wanted to do something special and fun to wrap up our anniversary year. While we have been active in various areas, including development of publishing technology concerning open and FAIR access and linkage for research outcomes and underlying data; and multiple EU-supported scientific projects, we have always been associated with our biodiversity journal portfolio.
Besides, who doesn’t like to learn about the latest curious creature that has evaded scientific discovery throughout human history up until our days? 😉
For the 37th time, experts from across the world to share and discuss the latest developments surrounding biodiversity data and how they are being gathered, used, shared and integrated across time, space and disciplines.
Between 17th and 21st October, about 400 scientists and experts took part in a hybrid meeting dedicated to the development, use and maintenance of biodiversity data, technologies, and standards across the world.
For the 37th time, the global scientific and educational association Biodiversity Information Standards (TDWG) brought together experts from all over the globe to share and discuss the latest developments surrounding biodiversity data and how they are being gathered, used, shared and integrated across time, space and disciplines.
This was the first time the event happened in a hybrid format. It was attended by 160 people on-site, while another 235 people joined online.
The TDWG 2022 conference saw plenty of networking and engaging discussions with as many as 160 on-site attendees and another 235 people, who joined the event remotely.
“It’s wonderful to be in the Balkans and Bulgaria for our Biodiversity Information and Standards (TDWG) 2022 conference! Everyone’s been so welcoming and thoughtfully engaged in conversations about biodiversity information and how we can all collaborate, contribute and benefit,”
“Our TDWG mission is to create, maintain and promote the use of open, community-driven standards to enable sharing and use of biodiversity data for all,”
she added.
Prof Lyubomir Penev (Pensoft) and Deborah Paul (TDWG) at TDWG 2022.
“We are proud to have been selected to be the hosts of this year’s TDWG annual conference and are definitely happy to have joined and observed so many active experts network and share their know-how and future plans with each other, so that they can collaborate and make further progress in the way scientists and informaticians work with biodiversity information,”
said Pensoft’s founder and CEO Prof. Lyubomir Penev.
“As a publisher of multiple globally renowned scientific journals and books in the field of biodiversity and ecology, at Pensoft we assume it to be our responsibility to be amongst the first to implement those standards and good practices, and serve as an example in the scholarly publishing world. Let me remind you that it is the scientific publications that present the most reliable knowledge the world and science has, due to the scrutiny and rigour in the review process they undergo before seeing the light of day,”
he added.

In a nutshell, the main task and dedication of the TDWG association is to develop and maintain standards and data-sharing protocols that support the infrastructures (e.g., The Global Biodiversity Information Facility – GBIF), which aggregate and facilitate use of these data, in order to inform and expand humanity’s knowledge about life on Earth.
It is the goal of everyone at TDWG to let scientists interested in the world’s biodiversity to do their work efficiently and in a manner that can be understood, shared and reused.
It is the goal of everyone volunteering their time and expertise to TDWG to enable the scientists interested in the world’s biodiversity to do their work efficiently and in a manner that can be understood, shared and reused by others. After all, biodiversity data underlie everything we know about the natural world.
If there are optimised and universal standards in the way researchers store and disseminate biodiversity data, all those biodiversity scientists will be able to find, access and use the knowledge in their own work much more easily. As a result, they will be much better positioned to contribute new knowledge that will later be used in nature and ecosystem conservation by key decision-makers.
On Monday, the event opened with welcoming speeches by Deborah Paul and Prof. Lyubomir Penev in their roles of the Chair of TDWG and the main host of this year’s conference, respectively.
The opening ceremony continued with a keynote speech by Prof. Pavel Stoev, Director of the Natural History Museum of Sofia and co-host of TDWG 2022.
Prof. Pavel Stoev (Natural History Museum of Sofia) with a presentation about the known and unknown biodiversity of Bulgaria during the opening plenary session of TDWG 2022.
He walked the participants through the fascinating biodiversity of Bulgaria, but also the worrying trends in the country associated with declining taxonomic expertise.
He finished his talk with a beam of hope by sharing about the recently established national unit of DiSSCo, whose aim – even if a tad too optimistic – is to digitise one million natural history items in four years, of which 250,000 with photographs. So far, one year into the project, the Bulgarian team has managed to digitise more than 32,000 specimens and provide images to 10,000 specimens.
The plenary session concluded with a keynote presentation by renowned ichthyologist and biodiversity data manager Dr. Richard L. Pyle, who is also a manager of ZooBank – the key international database for newly described species.
Keynote presentation by Dr Richard L. Pyle (Bishop Museum, USA) at the opening plenary session of TDWG 2022.
In his talk, he highlighted the gaps in the ways taxonomy is being used, thereby impeding biodiversity research and cutting off a lot of opportunities for timely scientific progress.
“There are simple things we can do to change how we use taxonomy as a tool that would dramatically improve our ability to conduct science and understand biodiversity. There is enormous value and utility within existing databases around the world to understand biodiversity, how threatened it is, what impacts human activity has (especially climate change), and how to optimise the protection and preservation of biodiversity,”
he said in an interview for a joint interview by the Bulgarian News Agency and Pensoft.
“But we do not have easy access to much of this information because the different databases are not well integrated. Taxonomy offers us the best opportunity to connect this information together, to answer important questions about biodiversity that we have never been able to answer before. The reason meetings like this are so important is that they bring people together to discuss ways of using modern informatics to greatly increase the power of the data we already have, and prioritise how we fill the gaps in data that exist. Taxonomy, and especially taxonomic data integration, is a very important part of the solution.”
Pyle also commented on the work in progress at ZooBank ten years into the platform’s existence and its role in the next (fifth) edition of the International Code of Zoological Nomenclature, which is currently being developed by the International Commission of Zoological Nomenclature (ICZN).
“We already know that ZooBank will play a more important role in the next edition of the Code than it has for these past ten years, so this is exactly the right time to be planning new services for ZooBank. Improvements at ZooBank will include things like better user-interfaces on the web to make it easier and faster to use ZooBank, better data services to make it easier for publishers to add content to ZooBank as part of their publication workflow, additional information about nomenclature and taxonomy that will both support the next edition of the Code, and also help taxonomists get their jobs done more efficiently and effectively. Conferences like the TDWG one are critical for helping to define what the next version of ZooBank will look like, and what it will do.”

During the week, the conference participants had the opportunity to enjoy a total of 140 presentations; as well as multiple social activities, including a field trip to Rila Monastery and a traditional Bulgarian dinner.
TDWG 2022 conference participants document their species observations on their way to Rila Monastery.
While going about the conference venue and field trip localities, the attendees were also actively uploading their species observations made during their stay in Bulgaria on iNaturalist in a TDWG2022-dedicated BioBlitz. The challenge concluded with a total of 635 observations and 228 successfully identified species.
Amongst the social activities going on during TDWG 2022 was a BioBlitz, where the conference participants could uploade their observations made in Bulgaria on iNaturalist and help each other successfully identify the specimens.
“Biodiversity provides the support systems for all life on Earth. Yet the natural world is in peril, and we face biodiversity and climate emergencies. The consequences of these include accelerating extinction, increased risk from zoonotic disease, degradation of natural capital, loss of sustainable livelihoods in many of the poorest yet most biodiverse countries of the world, challenges with food security, water scarcity and natural disasters, and the associated challenges of mass migration and social conflicts.
Solutions to these problems can be found in the data associated with natural science collections. DiSSCo is a partnership of the institutions that digitise their collections to harness their potential. By bringing them together in a distributed, interoperable research infrastructure, we are making them physically and digitally open, accessible, and usable for all forms of research and innovation.
At present rates, digitising all of the UK collection – which holds more than 130 million specimens collected from across the globe and is being taken care of by over 90 institutions – is likely to take many decades, but new technologies like machine learning and computer vision are dramatically reducing the time it will take, and we are presently exploring how robotics can be applied to accelerate our work.”
In his turn, Dr Donat Agosti, CEO and Managing director at Plazi – a not-for-profit organisation supporting and promoting the development of persistent and openly accessible digital taxonomic literature – said:
“All the data about biodiversity is in our libraries, that include over 500 million pages, and everyday new publications are being added. No person can read all this, but machines allow us to mine this huge, very rich source of data. We do not know how many species we know, because we cannot analyse with all the scientists in this library, nor can we follow new publications. Thus, we do not have the best possible information to explore and protect our biological environment.”

At the closing plenary session, Gail Kampmeier – TDWG Executive member and one of the first zoologists to join TDWG in 1996 – joined via Zoom to walk the conference attendees through the 37-year history of the association, originally named the Taxonomic Databases Working Group, but later transformed to Biodiversity Information Standards, as it expanded its activities to the whole range of biodiversity data.
“While this presentation is about TDWG’s history as an organisation, its focus will be on the heart of TDWG: its people. We would like to show how the organisation has evolved in terms of gender balance, inclusivity actions, and our engagement to promote and enhance diversity at all levels. But more importantly, where do we—as a community—want to go in the future?”,
Then, in the final talk of the session, Deborah Paul took to the stage to present the progress and key achievements by the association from 2022.
🤩Year in review by @idbdeb at #TDWG2022: many wonderful achievements & even more in the works!🙌 E.g.✅Memorandum of Understanding with Genomic Standards Consortium ✅new Mineralogy Task Group ✅new vision & mission statement ✅collaboration with @GBIF on the new data model.. 1/ pic.twitter.com/RZx8hlePOm
Deborah Paul reminds that – apart from the conference abstracts – the TDWG journal: Biodiversity Information Science and Standards (BISS) also welcomes full-lenght articles that demonstrate the development or application of new methods and approaches in biodiversity informatics.
Launched in 2017 on the Pensoft’s publishing platform ARPHA, the journal provides the quite unique and innovative opportunity to have both abstracts and full-length research papers published in a modern, technologically-advanced scholarly journal. In her speech, Deborah Paul reminded that BISS journal welcomes research articles that demonstrate the development or application of new methods and approaches in biodiversity informatics in the form of case studies.
Amongst the achievements of TDWG and its community, a special place was reserved for the Horizon 2020-funded BiCIKL project (abbreviation for Biodiversity Community Integrated Knowledge Library), involving many of the association’s members.
Having started in 2021, the 3-year project, coordinated by Pensoft, brings together 14 partnering institutions from 10 countries, and 15 biodiversity under the common goal to create a centralised place to connect all key biodiversity data by interlinking a total of 15 research infrastructures and their databases.
Deborah Paul also reported on the progress of the Horizon 2020-funded project BiCIKL, which involves many of the TDWG members. BiCIKL’s goal is to create a centralised place to connect all key biodiversity data by interlinking 15 key research infrastructures and their databases.
In fact, following the week-long TDWG 2022 conference in Sofia, a good many of the participants set off straight for another Bulgarian city and another event hosted by Pensoft. The Second General Assembly of BiCIKL took place between 22nd and 24th October in Plovdiv.

The Pensoft team at TDWG 2022 were happy to become the hosts of the 37th TDWG conference.
By the time authors – who have acknowledged third-party financial support in their research papers submitted to a journal using the Pensoft-developed publishing platform: ARPHA – open their inboxes to the congratulatory message that their work has just been published and made available to the wide world, a similar notification will have also reached their research funder.
This automated workflow is already in effect at all journals (co-)published by Pensoft and those published under their own imprint on the ARPHA Platform, as a result of the new partnership with the OA Switchboard: a community-driven initiative with the mission to serve as a central information exchange hub between stakeholders about open access publications, while making things simpler for everyone involved.
All the submitting author needs to do to ensure that their research funder receives a notification about the publication is to select the supporting agency or the scientific project (e.g. a project supported by Horizon Europe) in the manuscript submission form, using a handy drop-down menu. In either case, the message will be sent to the funding body as soon as the paper is published in the respective journal.
“At Pensoft, we are delighted to announce our integration with the OA Switchboard, as this workflow is yet another excellent practice in scholarly publishing that supports transparency in research. Needless to say, funding and financing are cornerstones in scientific work and scholarship, so it is equally important to ensure funding bodies are provided with full, prompt and convenient reports about their own input.”
comments Prof Lyubomir Penev, CEO and founder of Pensoft and ARPHA.
“Research funders are one of the three key stakeholder groups in OA Switchboard and are represented in our founding partners. They seek support in demonstrating the extent and impact of their research funding and delivering on their commitment to OA. It is great to see Pensoft has started their integration with OA Switchboard with a focus on this specific group, fulfilling an important need,”
adds Yvonne Campfens, Executive Director of the OA Switchboard.

Recent botanical expeditions in Caquetá department (southeastern Colombia) have uncovered the enormous richness of plant species in this region. Research led by W. Trujillo in the Andean foothills has allowed the unveiling of at least 90 species of Piper in the region, highlighting northwestern Amazonia as one of the richest regions for the genus. Here, four new species of Piper new to science are described.

This publication is the result of a collaboration between three institutions and five researchers, each contributing their experience and strengths: main author William Trujillo (Fundación La Palmita), with M. Alejandra Jaramillo (Universidad Militar Nueva Granada), Edwin Trujillo Trujillo, Fausto Ortiz and Diego Toro (Centro de Investigaciones Amazónicas Cesar Augusto Estrada Gonzalez, Universidad de la Amazonia). W. Trujillo, a native of Caquetá, has dedicated the last ten years to the study of Piper species in his department. M. A. Jaramillo has been studying the phylogenetics, ecology and evolution of the genus for more than 20 years. Edwin Trujillo is a local botanist well versed in the flora of Caquetá and the Colombian Amazon. Fausto Ortiz and Diego Toro are trained in plant molecular biology methods and lead this area at Universidad de la Amazonia.

Caquetá is situated where the Andes and the Amazon meet in southern Colombia, in the northwestern Amazon. Several researchers have highlighted the importance of the northwest Amazon for high biodiversity and our lack of knowledge of the region. Fortunately, ongoing studies led by W. Trujillo and E. Trujillo are unveiling the immense diversity of plants in Caquetá, showing the importance of local institutions in the knowledge of Amazonian flora. There are many species in the region yet to be described and discovered. Leadership from local institutions and collaboration with experts are vital to appreciating the great relevance of plants from Caquetá.

Two of the species in this manuscript (Piper indiwasii and Piper nokaidoyitau) bear names inspired by the indigenous tribes that live in Caquetá. The name indiwasii comes from a Quechua word meaning “house of the sun” and is also the name of one of the National Parks where the species lives in southern Colombia. In its turn, nokaidoyitau comes from the Murui language and means “tongue of the toucan,” the way the Murui Indians of the Colombian Amazon call the species of Piper. In fact, local communities rely on these plants for medicinal purposes, using them against inflammations or parasites, or to relieve various ailments.

Furthermore, the other two new species (Piper hoyoscardozii and Piper velae) honor two Amazonian naturalists, the authors’ dear friend Fernando Hoyos Cardozo, and Dr. Vela. Fernando, who was a devoted botanist and companion in W. Trujillo’s botanical expeditions. Dr. Vela, a naturalist and conservation enthusiast who sponsored Trujillo’s trips, was killed in 2020. We miss him immensely. His death is a significant loss for the environment in Caquetá.

The team’s joint effort will continue to describe new species, explore unexplored regions, and inspire new and seasoned researchers to dive into the magnificent diversity of the Colombian Amazon.

While every Flora publication is an incredibly valuable scientific resource, Vol. 45 is the first in the series to be made available in digital format, following its publication in the open-access journal PhytoKeys
The 45th volume of the Flora of Cameroon pilots a novel “Flora” section in the journal to promote accessibility and novelty in plant taxonomy
Dedicated to Annonaceae, the 45th volume of the Flora of Cameroon is the result of over 15 years of work on the systematics of this major pantropical group, commonly known as the Custard apple family or the Soursop family, and its diversity in one of the most biodiverse African countries, whose flora has remained understudied to this date.
In their publication, the authors: Thomas L. P. Couvreur, Léo-Paul M. J. Dagallier, Francoise Crozier, Jean-Paul Ghogue, Paul H. Hoekstra, Narcisse G. Kamdem, David M. Johnson, Nancy A. Murray and Bonaventure Sonké, describe 166 native taxa representing 163 species in 28 native genera, including 22 species known solely from Cameroon. The team also provides keys to all native genera, species, and infraspecific taxa, while a detailed morphological description and a distributional map are provided for each species.

Amongst the findings featured in the paper is the discovery of a previously unknown species of a rare tree that grows up to 6 metres and is so far only known from two localities in Cameroon. As a result of their extensive study, the authors also report that the country is the one harbouring the highest number of African species for the only pantropical genus of Annonaceae: Xylopia.
While every Flora publication presents an incredibly valuable scientific resource due to its scale and exhaustiveness, what makes Volume 45 of the Flora of Cameroon particularly special and important is that it is the first in the series to be made available in digital format, following its publication in the peer-reviewed, open-access journal PhytoKeys.
Available in the open-access scholarly journal PhytoKeys, the latest volume of the Flora of Cameroon features perks like displaying occurrences of treated taxa side-by-side when reading the publication in HTML.
As such, it is not only available to anyone, anywhere in the world, but is also easily discoverable and minable online, as it benefits from the technologically advanced publishing services provided by the journal that have been specially designed to open up biodiversity data. While the full-text publication is machine-readable, hence discoverable by search algorithms, various data items, such as nomenclature, descriptions, images and occurrences, are exported in relevant specialised databases (e.g. IPNI, Plazi, Zenodo, GBIF). In their turn, the readers who access the HTML version of the publication may enjoy the benefits of this semantically enriched format, as they navigate easily within the text, and access further information about the mentioned and hyperlinked taxa.
In fact, the Annonaceae contribution is the first to use the newly launched publication type in PhytoKeys: Flora.
Yet, to keep up with the much treasured tradition, the new publication is also available in print format, accompanied by its classic cover design.

When we spoke with the team behind the Flora, we learnt that they are all confident that having the new volume in both print and open-access digital formats, is expected to rekindle the interest in the series, especially amongst younger botanists in Cameroon.
“The hybrid publication is a response to the reluctance to publish new volumes of these series. The hybrid version pioneered in Volume 45, is an opportunity for any scientist to freely access this fundamental work, and eventually use it in future studies. Also, the online and open access format is intended to stimulate botanists to author family treatments without the fear of not having their work published online in an academic journal with an Impact Factor,”
“The chosen format marks a qualitative leap in the presentation of the Flora of Cameroon and will be of interest to young botanists, who until now might have found the old presentation of the Flora unrewarding,” adds Prof. Bonaventure Sonké, last author and Head of the Biology Department of the Université de Yaoundé 1, Cameroon.

As an extensive contribution to a previously understudied area of research, the value of the new publication goes beyond its appreciation amongst plant taxonomists.
“The Flore du Cameroun series is considered as a showcase of the National Herbarium of Cameroon, which promotes knowledge of the flora of Cameroon at all levels. Being able to identify plants and trees is the first and foremost step to addressing the issue of ill-management of forest regions in Cameroon and the Congo Basin as a whole. If planning continues to rely on badly made identification, the forecasts about our resources are not good at all,” says Prof. Jean Betti Largarde, Head of the National Herbarium of Cameroon, and Editor-in-Chief of the Flora of Cameroon.

“Plant taxonomy is the basic discipline for the knowledge, conservation and sustainable management of biodiversity, including animals, plants and habitats. Young Cameroonian botanists, privileged to having such floristic richness in their country, are invited to take an interest in it. This is the field that opens the mind and makes it possible to address all other aspects of botanical research and development in relation to natural resources,”
adds Jean Michel Onana.

For almost 12 years now, PhytoKeys has been providing high-quality, peer-reviewed resources on plant taxonomy, phylogeny, biogeography and evolution, freely available open access.
PhytoKeys, Pensoft’s open-access, peer-reviewed botany systematics journal, has been around for over a decade. Since its launch in 2010, it has published almost 30,000 pages in more than 1,200 works. As PhytoKeys hits the milestone of its 200th issue – which presented a monograph of wild and cultivated chili peppers – there’s plenty to look back to.
For almost 12 years now, PhytoKeys has been providing high-quality, peer-reviewed resources on plant taxonomy, phylogeny, biogeography and evolution, freely available open access.
As our flagship botany journal, PhytoKeys is part of our concerted effort to help advance taxonomic studies. The more we know about biodiversity, the better we are equipped to protect it.
This is why, in a time when so many species are getting wiped out from the face of the Earth before we even become aware of their existence, it is truly exciting that we can sometimes be the bearer of good news.
Take the story of Gasteranthus extinctus from Ecuador – doesn’t its name sound a lot like extinct to you? That’s because the scientists named it based on specimens collected some 15 years earlier. So, they suspected that during the time in between, the species had already become extinct.
Yet, this is a happy-ending story: in a surprising turn of events, the plant was rediscovered 40 years after its last sighting. Gasteranthus extinctus is the hopeful message that we all needed: there’s still so much we can do to protect biodiversity.
Long believed to have gone extinct, Gasteranthus extinctus was found growing next to a waterfall at Bosque y Cascada Las Rocas, a private reserve in coastal Ecuador containing a large population of the endangered plant. Photo by Riley Fortier.
Over the time, we saw some ground-breaking botany research. We welcomed some record-breaking new plant species, such as the 3.6-meter-tall begonia, and the smallest Rafflesia that measures around 10 cm in diameter.
We witnessed the discoveries of some truly beautiful flowers.
We helped unveil some taxonomic mysteries – like the bamboo fossil that wasn’t a bamboo, or the 30-meter new species of tree that was “hiding in plain sight”.
Published less than two months ago, Nepenthes pudica broke all kinds of popularity records at PhytoKeys: it became the journal’s all-time most popular work, with thousands of shares on social media, more than 70 news outlets covering its story, and upward of 70,000 views on YouTube.
Publishing in PhytoKeys is always a pleasure. I appreciate the quick but rigorous peer review process and reasonably short time from initial submission to the final publication.
Every week, PhytoKeys publishes dozens of pages of quality botany research. Every week, we’re amazed at the discoveries made by botanists around the world. In a field that is so rapidly evolving, and with so much remaining to be unveiled, the future sure seems promising!
The three most important taxonomic ranks used to classify organisms are family, genus and species, especially the latter two, which make up the scientific binomials used to communicate about biodiversity, and indeed about all aspects of biology. While the description of a new plant family is now a very rare event, the same is not true for genera. Indeed, delimitation of genera within many plant families remains in a state of considerable flux, because many traditionally recognized genera do not correspond to evolutionary groups. This causes unwelcome instability in scientific names of species and is why work to delimit genera lies at the heart of much current research in systematic botany.
This is very much the case for subfamily Caesalpinioideae, the second largest subfamily of the legume family, which is the focus of this new special issue of the open-access, peer-reviewed journal PhytoKeys. With around 4,600 species of mostly trees, shrubs and lianas, distributed right across the tropics in rainforests, dry forests and savannas, Caesalpinioideae represent a spectacularly diverse lineage of tropical woody plants.
New analyses of DNA sequences of 420 species of Caesalpinioideae presented herereveal that 22 of the 152 currently recognized genera do not coincide with natural evolutionary groups, i.e., in phylogenetic terms, they are non-monophyletic. The aim of this special issue is to re-define as many of these problematic genera as possible in order to bring them into line with natural evolutionary lineages. To achieve this, nine new genera of Caesalpinioideae are described, five previously recognized genera are resurrected, and three genera shown to be nested within other genera are consigned to synonymy.
Many of the species in these new genera are important, conspicuous, ecologically abundant, and, in some cases, geographically widespread trees in tropical forests. For example, the three species of the new genus Osodendron are important large canopy trees in tropical rain forests and riverine gallery forests across a broad swathe of west and central Africa. In recent decades these species have been successively placed in different genera including Cathormion, Samanea and Albizia, among others. The neglected generic placement of these African trees has finally been resolved via analyses of DNA sequences, and a new generic home for them has been established.
In contrast, two of the genera newly described in this special issue, Mezcala and Boliviadendron, each with just a single species, are much more elusive plants occupying very narrowly restricted geographical ranges. Mezcala occurs across just a few square km of the central Balsas Depression in south-central Mexico and Boliviadendron is known from just two interior valleys of the Bolivian Andes. Establishing these two lineages as distinct genera highlights the importance of conserving these globally rare evolutionary lineages.
Choosing names for new taxa is one of the delights and privileges of the practising taxonomist. Derivations of the names of the nine new genera described in this special issue span features of the plants themselves and the locations where they grow, as well as names of fellow legume researchers honoured with genera named in recognition of their contributions. For example, Osodendron is named after ‘Oso’ a food that is prepared in West Africa from seeds of one of the species now placed in the new genus. Mezcala is named for the indigenous Mezcala culture of the Balsas region in Mexico where the genus is found. Boliviadendron is named as such because it is a tree that grows in Bolivia and nowhere else. The new genus name Heliodendron is derived from the Greek helios (sun) and dendron (tree) because it grows in the sunshine state of Queensland in Australia and its flowers are arranged in sun-like globose heads.

Finally, Naiadendron celebrates the Brazilian Amazon where the genus grows, and the famous German botanist Carl Friedrich Philipp von Martius (1794–1868), who named the Brazilian Amazon after the Naiads, Greek mythology’s nymphs of freshwater.
Four of the genera newly described in this Special Issue are named after prominent contemporary legume taxonomists, three women and one man: Gretheria for Rosaura Grether, a Mexican specialist on the genus Mimosa, Ricoa for Lourdes Rico, another Mexican botanist who worked on legumes based at Kew, Marlimorimia, in honour of Marli Pires Morim of the Jardim Botânico do Rio de Janeiro, Brazil in recognition of her contributions to the taxonomy of mimosoid legumes, and Gwilymia named for Gwilym Lewis, in honour of one of the world’s most experienced and productive legume taxonomists who is legume research leader in the Herbarium at the Royal Botanic Gardens, Kew.

One of the central achievements of the work on Caesalpinioideae presented in this Special Issue is that for the first time a truly pantropical analysis of this large group of plants has been accomplished. A global synthesis is essential to work out how many genera there are.
For example, by sampling across Asia, Africa, Madagascar, North and South America, it has become clear that the Old World species of the important pantropical genus Albizia are not closely related to Albizia in the Americas, prompting splitting of the genus and resurrection of the name Pseudalbizziafor the New World species. All elements of the former Albizia – the last so-called ‘dustbin’ genus in the mimosoid legumes – are accounted for in this special issue (here, here and here). Similarly, the genus Prosopis, one of the most important silvopastoral tree genera of the dryland tropics, has traditionally encompassed elements spanning the New and Old Worlds that are here shown to comprise four distinct evolutionary lineages, two in the Old World and two in the Americas, here treated as four separate genera.
Changes to the scientific names of species are not always immediately welcomed by users, but over time, establishment of a classification that is based on robust evidence about evolutionary history will result in greater nomenclatural stability and in named taxa that are aligned with natural groups and hence biologically more informative. This special issue, reshaping the generic system of a species-rich group of legumes, is an important step towards that goal.

What we thought we knew about carnivorous plants was swiftly called into question after scientists discovered a new species in the Indonesian province of North Kalimantan, on the island of Borneo. Nepenthes pudica is what scientists call a pitcher plant – it has modified leaves known as pitfall traps or pitchers, where it captures its prey. In a strategy so far unknown from any other species of carnivorous plant with pitfall traps, this one operates underground, catching its prey in the soil.

“We found a pitcher plant which differs markedly from all the other known species,”
says Martin Dančák of Palacký University in Olomouc, Czech Republic, lead author of the study, published in the journal PhytoKeys, where his team described the new species.
“In fact, this species places its up-to-11-cm-long pitchers underground, where they are formed in cavities or directly in the soil and trap animals living underground, usually ants, mites and beetles”, he adds.

Only three other groups of carnivorous plants are known to trap underground prey, but they all use very different trapping mechanisms and, unlike Nepenthes pudica, can catch only minuscule organisms.
The plant forms specialised underground shoots with entirely white, chlorophyll-free leaves. In addition to lacking their normal green pigmentation, the leaves supporting the pitchers are reduced to a fraction of their normal size. The pitchers, however, retain their size and often also their reddish colour.
If no cavity is available, the shoots grow directly into the soil, as seen here where a bunch of pitchers was excavated from the ground. Photo by Martin Dančák
“Interestingly, we found numerous organisms living inside the pitchers, including mosquito larvae, nematodes and a species of worm which was also described as a new species”,
explains Václav Čermák of the Mendel University in Brno, Czech Republic, who was also part of the research team.
The newly discovered species grows on relatively dry ridge tops at an elevation of 1100–1300 m. According to its discoverers, this might be why it evolved to move its traps underground. “We hypothesise that underground cavities have more stable environmental conditions, including humidity, and there is presumably also more potential prey during dry periods,” adds Michal Golos of the University of Bristol, United Kingdom, who also worked on this curious plant.

A series of lucky events back in 2012 led to the discovery of the species. Ľuboš Majeský of Palacký University Olomouc, part of the research team, recounts the key moment: “During a several-day trip with our Indonesian colleagues to a previously unexplored mountain, randomly chosen from a number of candidates, we noted plants which were undoubtedly Nepenthes but produced no pitchers. After a careful search, we found a couple of aerial pitchers, a few juvenile terrestrial ones, and one deformed pitcher protruding from the soil.”
“At first, we thought it was an accidentally buried pitcher and that local environmental conditions had caused the lack of other pitchers. Still, as we continued to find other pitcherless plants along the ascent to the summit, we wondered if a species of pitcher plant might have evolved towards loss of carnivory, as seen in some other carnivorous plants. But then, when taking photos, I tore a moss cushion from a tree base revealing a bunch of richly maroon-coloured pitchers growing from a short shoot with reduced leaves entirely lacking chlorophyll.”
The group then checked the other encountered plants and found that all of them had underground shoots with pitchers, confirming that this species specifically targets the underground environment.
The scientific name Nepenthes pudica points to the plant’s curious behaviour: it is derived from the Latin adjective pudicus, which means bashful and reflects the fact that its lower pitchers remain hidden from sight.
Nepenthes pudica is endemic to Borneo.
“This discovery is important for nature conservation in Indonesian Borneo, as it emphasises its significance as a world biodiversity hotspot. We hope that the discovery of this unique carnivorous plant might help protect Bornean rainforests, especially prevent or at least slow the conversion of pristine forests into oil palm plantations,”
concludes Wewin Tjiasmanto of Yayasan Konservasi Biota Lahan Basah, who helped discover the new species.
