Hidden biodiversity underfoot: DNA barcoding of Taiwanese forest beetles

The intricate world beneath our feet holds secrets that are only now being unveiled, as researchers embark on a groundbreaking project to explore the hidden diversity of forest leaf litter beetles in Taiwan.

Guest blog post by the research team led by Martin Fikácek and Fang-Shuo Hu, based on their paper published in Deutsche Entomologische Zeitschrift.

Forest leaf litter, often likened to terrestrial coral reefs, supports an astonishing variety of life. Among the myriad arthropods dwelling in this ecosystem, beetles emerge as the most common and speciose group. Despite their abundance, our understanding of leaf litter beetles remains limited due to the challenges posed by their sheer numbers, small sizes, and high local endemism.

Unlocking the Mystery with DNA Barcoding

To overcome these challenges, a team of researchers has initiated the Taiwanese Leaf Litter Beetles Barcoding project. Leveraging DNA barcoding, the project aims to create a comprehensive reference library for these elusive beetles. DNA barcoding, a technique using short mitochondrial fragments, accelerates the analysis of entire faunas and aids in the identification of species. The goal is to provide a valuable resource for researchers, ecologists, conservation biologists, and the public.

A Collaborative Journey with Taxonomists

The success of the Taiwanese Leaf Litter Beetles Barcoding project hinges on the invaluable contribution of taxonomists, who play a pivotal role in this groundbreaking research. Recognizing the specialized knowledge required for precise genus and species identifications, the researchers diligently consulted with specialists for each family represented in the extensive dataset.

In cases where these taxonomic experts provided crucial assistance, they were not merely acknowledged but offered co-authorship, acknowledging the significant commitment and expertise they bring to the project. Many taxonomists devote their entire lives to the meticulous study of specific beetle groups, and this collaboration underscores the importance of their dedication. The researchers emphasize the fairness of extending co-authorship to these taxonomic experts, acknowledging their indispensable role in advancing our understanding of Taiwan’s leaf litter beetle fauna.

Rich Beetle Diversity in Taiwan

Taiwan, nestled in the western Pacific, boasts a rich biodiversity resulting from its location at the crossroads of the Oriental and Palearctic biogeographical regions. Beetles, with over 7,700 recorded species belonging to 119 families, stand out as a particularly diverse insect order on the island. Despite this wealth of species, taxonomic research on beetles in Taiwan has been fragmented, and the study of leaf litter beetles has relied heavily on collections from past decades.

The current dataset, based on specimens collected in the Huisun Recreation Forest Area in 2019–2021, comprises 4,629 beetles representing 334 species candidates from 36 families. The DNA barcoding approach has not only allowed for efficient species identification but has also provided a glimpse into the intricate world of beetle larvae, enhancing our understanding of their biology and ecological roles. This comprehensive dataset marks a significant step forward in unraveling the mysteries of Taiwan’s diverse beetle fauna.

Project Goals, Progress, and Future Outlook

The Taiwanese Leaf Litter Beetles Barcoding project is dedicated to a three-fold mission: conducting an extensive study of leaf litter beetles, documenting their diversity in Taiwan, and providing a reliable tool for quick identification. The researchers have published the first set of DNA barcodes, unveiling taxonomic insights such as the description of a new species and several newly recorded taxa.

While the dataset is geographically limited to a single forest reserve in central Taiwan, it efficiently demonstrates the challenges of studying subtropical and tropical leaf litter beetle faunas. The integration of DNA barcoding and morphology proves instrumental in unraveling the mysteries of this species-diverse ecosystem. Looking ahead, the team plans to expand their sampling across Taiwan, covering diverse regions, altitudinal zones, and forest types.

Continuous updates to the DNA barcode dataset will serve as a valuable resource for future studies, maintaining a balanced approach that recognizes DNA barcoding as an efficient complement to traditional taxonomic methods.

New reptile on the block: A new agamid lizard species discovered in China

Measuring less than 9 cm with an orange tongue, it inhabits subtropical and tropical forests, thriving in various landscapes including urban areas.

A new agamid joins Asia’s rich reptile fauna, officially described as new to science in the open-access journal ZooKeys.

Calotes wangi.

“From 2009 to 2022, we conducted a series of field surveys in South China and collected a number of specimens of the Calotes versicolor species complex, and found that the population of what we thought was Calotes versicolor in South China and Northern Vietnam was a new undescribed species and two subspecies,” says Yong Huang, whose team described the new species.

Calotes wangi hainanensis, a newly discovered subspecies of Calotes wangi.

Wang’s garden lizard (Calotes wangi) is less than 9 cm long, and one of its distinguishing features is its orange tongue.

Calotes wangi is found in subtropical evergreen broad-leaved forests and tropical monsoon forests in southern China and northern Vietnam, mostly in mountainous areas, hills and plains on forest edges, arable land, shrub lands, and even urban green belts. It is active at the edge of the forest, and when it is in danger, it rushes into bushes or climbs tree trunks to hide. Investigations found that the lizards lie on sloping shrub branches at night, sleeping close to the branches,” says Yong Huang.

It is active from April to October every year, while in the tropics it is active from March to November or even longer, and eats a variety of insects, spiders, and other arthropods.

For now, the researchers estimate that the new species is not threatened, but they do note that in some areas its habitat is fragmented.

“In addition, their bodies are used medicinally and the lizards are also eaten,” they write in their research paper.

This is why they suggest that the local government strengthen the protection of their ecological environment and pay close attention to the population dynamics.

Same and different: A new species of pit viper from Myanmar

In a collaborative study involving institutions from Singapore, Malaysia, Germany, and the UK, scientists have discovered a new species of pit viper from Myanmar that is both similar and different from its adjacent sister species.

Finding and describing new species can be a tricky endeavor. Scientists typically look for distinctive characters that can differentiate one species from another. However, variation is a continuum that is not always easy to quantify. At one extreme, multiple species can look alike even though they are different species—these are known as cryptic species. At the other extreme, a single species can be highly variable, creating an illusion of being different species. But what happens when you encounter both extremes simultaneously?

Herpetologist Dr Chan Kin Onn (previously at the Lee Kong Chian Natural History Museum, Singapore, now with the University of Kansas Biodiversity Institute and Natural History Museum, USA) led a study describing a new species of pit viper from Myanmar that is both similar and different from its sister species. The discovery is published in the open-access journal ZooKeys.

“Asian pit vipers of the genus Trimeresurus are notoriously difficult to tell apart, because they run the gamut of morphological variation. Some groups contain multiple species that look alike, while others may look very different but are actually the same species,” they say.

The redtail pit viper (Trimeresurus erythrurus) occurs along the northern coast of Myanmar and is invariably green with no markings on its body. A different species called the mangrove pit viper (Trimeresurus purpureomaculatus) occurs in southern Myanmar. This species typically has distinct dorsal blotches, and incredibly variable dorsal coloration including gray, yellow, brown, and black, but never green. Interestingly, in central Myanmar, sandwiched between the distribution of the redtail pit viper and the mangrove pit viper, a unique population exists that is green with varying degrees of blotchiness, which appears to be a blend between the redtail pit viper and the mangrove pit viper.

“This mysterious population in central Myanmar baffled us and we initially thought that it could be a hybrid population,” the researchers said. In a separate paper, Dr Chan used modern genomic techniques and determined that the population in central Myanmar was actually a distinct species and not a hybrid population.

But this was not the end of the story. The researchers discovered another surprise when they examined the snake’s morphological features: they found that the new species was also highly variable. Certain populations are dark green with distinct blotches, easily distinguishable from its closest relative, the redtail pit viper, which is bright green with no blotches. However, some populations of the new species are bright green with no blotches and look virtually identical to the redtail pit viper.

“This is an interesting phenomenon, where one species is simultaneously similar and different from its closest relative (the redtail pit viper). We think that at some point in the past, the new species may have exchanged genes with the redtail pit viper from the north and the mangrove pit viper from the south,” says Dr Chan.

The new species is called the Ayeyarwady pit viper (Trimeresurus ayeyarwadyensis) in reference to the Ayeyarwady River, which is the largest and one of the most important rivers in Myanmar. The river forms an expansive delta that is bounded by the Pathein River to the west and the Yangon River to the east. These rivers and their associated basins also mark the westernmost and easternmost distribution boundaries of the Ayeyarwady pit viper.

Ecuador’s newest tarantulas: just discovered, two new species face imminent threats

In the depths of Ecuador’s wilderness, scientists have unveiled the presence of two new tarantula species from the slopes of the Andes in the western part of the country.

In the depths of Ecuador’s wilderness, scientists have unveiled the presence of two new tarantula species. Researchers of Universidad San Francisco de Quito found them on trees on the slopes of the Andes in the western part of the country.

Meet Ecuador’s newest tarantulas

One of them was found in late February 2023, 1.5 m above the forest floor in the foothill evergreen forest of the Cordillera Occidental . Just discovered, it is already seriously threatened as people use its habitat for mining and agriculture. Its scientific name reflects this vulnerability: the tarantula is called Psalmopoeus chronoarachne, from the Greek words for “time” and “spider.”

Psalmopoeus chronoarachne.

“The compound word refers to the adage that these spiders could ‘have their time counted’ or reduced by impactful anthropogenic activities. The name addresses conservation concerns about the survival and prevalence of spider species in natural environments,” they write in their paper, which was just published in the open-access journal ZooKeys.

The other newly discovered tarantula has an even more curious name: Psalmopoeus satanas. “It is appropriately named because the initial individual that was collected had an attitude!” says researcher Roberto J. León-E, who first spotted it in a bamboo fence in San José de Alluriquín. The spider immediately exhibited defensive behavior; “this behavior then transformed into fleeing, where the spider made quick sporadic movements, nearly too fast to see.”

Psalmopoeus satanas.

It was the first tarantula he ever caught.

“The members of the Mygalomorphae Research Group in the Laboratory of Terrestrial Zoology at Universidad San Francisco de Quito grew very fond of this individual during its care, in spite of the individual’s bad temperament and sporadic attacks (reason for the nickname),” he writes in the paper.

The species, which can be found in in the north of the Cordillera Occidental of the Andes at about 900 m above sea level, is facing serious threats as its habitat is degraded, ever declining, and severely fragmented by cropland and mining concessions and expanding urban and agricultural territories.

Critically endangered: threats to tarantula survival

“It is important to consider that the areas in which these arthropods live are not under legal protection. The implementation of protected areas in these localities is essential to maintain the remaining population of these endangered species and to encourage research on the remaining undescribed or unknown tarantula species in the area,” says Pedro Peñaherrera-R, who led the research on these animals.

This makes the region highly vulnerable to both legal and illegal mining operations that extract metals such as copper, silver, and gold, introducing pollutants to its ecosystems.

The implementation of stricter regulations and penalties for illegal mining or other extracting-related activities, including specimen smuggling, might help these species survive. Likewise, the engaging and educating of local communities about the importance of biodiversity conservation is essential to avoid further extinction.

 “We encourage future work by Ecuadorian and international researchers, organisations, and governments to effectively understand the reality about the threat of tarantula smuggling and the required conservation status of each species in the country.” Says Roberto J. León-E.

Based on initial conservation assessments, both tarantulas meet the criteria for being considered Critically Endangered by International Union for Conservation of Nature.

“It is essential to consider the potential loss of both P. chronoarachne and P. satanas and the ecological consequences that would result from their extinctions. These species may serve essential roles in the stratified micro-ecosystems in their respective areas,” the researchers write in their paper.

The dark side: illegal trade in wild tarantulas

Illegal trade in wild tarantulas as pets is also a latent threat, not only to these two species, but to Ecuadorian tarantulas in general. Many tarantula species can be found for sale online on various websites and Facebook groups. “During the writing of this article and the publication of another article, we found that a species that we described (Neischnocolus cisnerosi) is currently in the illegal pet trade!” says Pedro Peñaherrera-R.

After studying papers on wild-caught pet-trade specimens, the researchers conclude that the issue has been going on for more than 30 years in the country. “Although this series of publications encouraged research on Ecuadorian tarantulas previously ignored for centuries, they also functioned as catalysts within the exotic pet-trade hobby, aiding in obtaining these species and further encouraging people to collect undescribed species,” says Pedro Peñaherrera-R with concern.

Novel bacteria identification methods might help speed up disease diagnosis

The technique, applied on turtle skin in this study, allows for the rapid detection of Pseudomonas bacteria, which can cause various human diseases.

Why is it important to study bacteria?

Pseudomonas aeruginosa is a bacterial strain that can be responsible for several human diseases: the most serious include malignant external otitis, endophthalmitis, endocarditis, meningitis, pneumonia, and septicemia.

The environments in which these bacteria are most frequently found include soil, plants, and water. They can even be found on human and animal skin, without causing illness, in a process known as bacterial colonisation. Microbiological research can help establish the cause of certain infectious diseases, making it easier to choose the best treatment. This is why it is important to find a quick and easy way to identify these bacteria. A new study, published in the open-access journal BioRisk, explored this by applying spectroscopic techniques for quick analysis directly from an object, which, in this case, was turtle skin.

“Microbial organisms play key roles in animal health and ecology. The European pond turtle often lives in city Zoo gardens and private houses. Often, the most commonly found bacteria from turtle skin surfaces was Pseudomonas species,” says Aleksandrs Petjukevics of Daugavpils University, whose team conducted the study.

What is Raman spectroscopy?

“Classical microbiological research techniques have several disadvantages: first of all, it is a rather lengthy process. The minimum period is 3-4 days, but many days and even weeks may pass before the isolated pathogen is accurately identified, and it uses expensive chemicals and resources,” says Aleksandrs Petjukevics. As an alternative, spectrometry makes it possible to identify a prepared sample of a microorganism while reducing the identification time to 5-30 minutes.

Raman spectra represent an ensemble of signals that arise from the molecular vibrations of individual cell components of gram-negative bacteria, integrating over proteins, lipids, and carbohydrates. “This non-destructive chemical analysis technique provides detailed information about chemical structure, phase and polymorphy, crystallinity, and molecular interactions. It is based on the interaction of light with the chemical bonds within a material,” he says.

Research results and implications

The study’s findings showed that Pseudomonas bacteria can be quickly identified using this detection technology, with excellent analytical and diagnostic sensitivity, making it a dependable technique.

Unlike other methods, this technique does not require long-term bacterial sample preparation and expensive reagents, which makes it promising for studying other strains of bacteria.

“This study demonstrated the ability to obtain fast and high-quality Raman spectra of bacterial cells using vibrational spectroscopy,” says Aleksandrs Petjukevics. “Raman spectroscopy can be considered an express method for identifying microorganisms. It holds great potential for future research involving different microorganisms.”

Smithsonian’s Dr Torsten Dikow appointed Editor-in-Chief of ZooKeys

Dikow, an esteemed entomologist specialising in Diptera and cybertaxonomy, is the new Editor-in-Chief of the leading scholarly journal in systematic zoology and biodiversity

Esteemed entomologist specialising in true flies (order Diptera) and cybertaxonomy, Dr Torsten Dikow was appointed as the new Editor-in-Chief of the leading open-access peer-reviewed journal in systematic zoology and biodiversity ZooKeys.

Dikow is to step into the shoes of globally celebrated fellow entomologist and colleague at the Smithsonian and founding Editor-in-Chief of ZooKeys Dr Terry Erwin, who sadly passed away in May, 2020, leaving behind hefty scientific legacy and immeasurable admiration and fond memories

Today, Dikow is a Research Entomologist and Curator of Diptera and Aquatic Insects at the Smithsonian National Museum of Natural History (Washington, DC, USA), where his research interests encompass the diversity and evolutionary history of the superfamily Asiloidea – or asiloid flies – comprising curious insect groups, such as the assassin flies / robber flies and the mydas flies. Amongst an extensive list of research publications, Dikow’s studies on the diversity, biology, distribution and systematics of asiloid flies include the description of 60 species of assassin flies alone, and the redescription of even more through comprehensive taxonomic revisions.

Dikow obtained his M.S. in Zoology from the Universität Rostock (Germany) and Ph.D. in Entomology from Cornell University (New York, USA) with three years of dissertation research conducted at the American Museum of Natural History (AMNH). 

During his years as a postdoc at the Field Museum (Illinois, USA), Dikow was earnestly involved in the broader activities of the Encyclopedia of Life through its Biodiversity Synthesis Center (BioSynC) and the Biodiversity Heritage Library (BHL). There, he would personally establish contacts with smaller natural history museums and scientific societies, and encourage them to grant digitisation permissions to the BHL for in-copyright scientific publications. Dikow is a champion of cybertaxonomic tools and making biodiversity data accessible from both natural history collections and publications. He has been named a Biodiversity Open Data Ambassador by the Global Biodiversity Information Facility (GBIF).

Dikow is no stranger to ZooKeys and other journals published by the open-access scientific publisher and technology provider Pensoft. For the past 10 years, he has been amongst the most active editors and a regular author and reviewer at ZooKeysBiodiversity Data Journal and African Invertebrates.

“Publishing taxonomic revisions and species descriptions in an open-access, innovative journal to make data digitally accessible is one way we taxonomists can and need to add to the biodiversity knowledge base. ZooKeys has been a journal in support of this goal since day one. I am excited to lend my expertise and enthusiasm to further this goal and continue the development to publish foundational biodiversity research, species discoveries, and much more in the zoological field,”

said Dikow.

Dikow took on his new role at ZooKeys at a time when the journal had just turned 15 years on the scholarly publishing scene. In late 2020, the scientific outlet also marked the publication of its 1000th journal volume.

All good things come from above! DNA-based food analysis in the Leisler’s bat

Through the analysis of DNA traces in the droppings of a Leisler’s bat colony, researchers at LIB have now identified over 350 different insect species that were consumed by the bats.

Adequate food supply is a fundamental need and requirement for survival. To protect a species, it is often very helpful to know what that species prefers and frequently consumes. Through the analysis of DNA traces in the droppings of a Leisler’s bat colony, researchers at LIB (Leibniz Institute for the Analysis of Biodiversity Change) have now identified an astonishingly high number —over 350— different insect species that were consumed by the bats.

Especially for small animal species and those that are nocturnal, it can be extremely difficult to determine what they feed on. Identifying small prey insects or their remains is also rarely possible down to the exact species or family. In the case of the studied bat species, there is the additional challenge that it is a forest bat species that needs to be located first. “Following bats equipped with radio transmitters in the forest at night is quite special,” says Martin Koch, co-initiator of the study.

Design and installation of the guano trap (3 m) and roost entrance (9 m).

Fortunately — but also complicating matters — there are about 13 different bat species living in the investigated area near Bonn, in the forests of the Natura 2000 area ‘Waldreservat Kottenforst.’ Initially, as part of an EU Life+ project, roosts — the trees where the bats live — of the Leisler’s bats were identified, from which the study’s starting material was then obtained. This was done using a specially developed “guano trap.” The trap consists of approximately 2.2 square meters of mosquito netting stretched rectangularly.

It was installed about 3 meters high on the tree trunk, below the entrance to the roosting cavity at about 9 meters high. During the so-called “twilight swarming” after the nightly insect hunt, the bats return to the roosting cavity and initially circle the tree. They frequently perch briefly next to the cavity entrance and stick a small guano pellet to the trunk. Regularly, pellets fall and land in the mosquito netting under the cavity entrance. This “bat guano” was collected, fixed, and further processed in the laboratory.

“It’s fascinating how much DNA you can extract from a small amount of droppings and how much information we can draw from the DNA: from which bat species does the droppings come, and what has the bat eaten?” explains Dr. Kathrin Langen. Using the DNA contained in the droppings, our researchers were able to determine nine samples from nine different nights when only the target species swarmed around the roosting tree. On six other nights, other bats and a species of mouse were also active around the roosting tree. From the nine samples containing only the guano of the evening bat, an astonishingly rich menu was then reconstructed: the group consumed at least 126 different species of moths, 86 different species of flies and mosquitoes, 48 species of beetles, and a few dozen other various species of bugs, mayflies, caddisflies, and lacewings. Occasionally, spiders, harvestmen, lice, and other small animals were also consumed.

Timeline showing arthropod community composition at order level in the guano of N. leisleri, all three markers combined (COImldg, COIArt, 16S). With the exception of plots showing RRA assigned to major groups depending on sampling date (4C and 4F), read counts were not taken into account. A, D Number of species of each arthropod order detected at each time point; B, E Relative number of species per arthropod order as a percentage of the diet; C, F Species detected in each arthropod order, based on relative read abundances.

From the results, the team was able to deduce which of the three molecular genetic markers used worked best and provided the most species detections, a total of 358. “It’s incredibly satisfying to see what species lists come out at the end of all the lab work and bioinformatics,” says Dr. Sarah Bourlat, Head of the Metabarcoding Section at LIB, Bonn. However, the temporal course of the composition of the consumed insects was also interesting to observe: from late March to late June, the number of species in the guano steadily increases, only to decrease again by mid-August. This aligns very well with the activity patterns of certain insect groups.

The beech moth was the most frequently consumed butterfly, and a mayfly known as the transient virgin or ‘Uferaas’, was the most frequently consumed mayfly. The author team has listed the most important ecological parameters for the 18 key prey species in the study to contribute to better protecting the Leisler’s bat and the habitats needed by its prey insects.

Entangled “her”stories – How to create an open multi-linked dynamic dataset of plant genera named for women

Which plant genera do you know that are named for women? Who were/are they?

Guest blog post by  Siobhan Leachman, Sabine von Mering, Heather Lindon & Carmen Ulloa Ulloa

How it all began

A post on social media asked about plant genera named for women and sparked a lively discussion with many contributors. This simple question was not as easily answered as initially thought. The resulting informal working group tackled this topic remotely during the COVID-19 pandemic and beyond. The team was motivated by the desire to amplify the contribution of women to botany through eponymy. The work of this team has so far resulted in a paper in Biodiversity Data Journal, presentations at several conferences, and a linked open dataset.

Prior to our international collaboration, no dataset was available to answer these simple questions and the required information was scattered in many different data sources. We set out to bring these data together and in doing so developed and refined our workflow. Our data paper documents this innovative workflow bringing together the various data elements needed to answer our research questions. Ultimately we created a Linked Open Data (LOD) dataset that amplified the names of women and female mythological beings celebrated through generic names of flowering plants.

Linking the Data

During our research process we focused on pulling data from a wide variety of sources while at the same time proactively sharing the data generated as widely as possible. This was done by adding and linking it to multiple public databases and sources (push-pull) including the International Plant Name Index (hereafter IPNI), Tropicos®, Wikidata, Bionomia and the Biodiversity Heritage Library (hereafter BHL).

Visualisation of our workflow to create a working list of flowering plant genera named for women. 

For our list of genera, each of the protologues were reviewed to confirm the etymology or eponymy. To find the generic prologues, we searched botanical databases such as IPNI and Tropicos, openly accessible providers of digital publications and other digital libraries and websites that provide free access to such publications. Here the BHL was invaluable as the majority of protologues and many other relevant publications were openly accessible through this digital library. Where no digital publication was available we accessed scientific literature through our affiliated institutions.

For the women, our starting point was the “Index of Eponymic Plant Names – Extended Edition” by Lotte Burkhardt (2018). We manually extracted all genera honouring women.  This dataset was supplemented with other sources including IPNI (2023), Mari Mut (2017-2021), a 2022 updated version of Burkhardt’s document (Burkhardt 2022), as well as suggestions received from colleagues and generated from our own research.

We collected the following information as structured data: information on the woman honoured, the genera named in honour of the woman, the year and place of the protologue or original publication (the nomenclatural reference), the author(s) of the genus name, and the link to the protologue or original publication if available online.

Wikidata

Wikidata was the central data repository and linking mechanism for this project as it provided structured data that can be read and edited by humans and machines and it acts as a hub for other identifiers. As such Wikidata played a central role in semantic linking and enriching of our data.

Wikidata items for the plant genera were created or enriched with information about the name, the author(s) of the genus and the year of publication. Those statements were referenced using the original publication. If the protologue was available on BHL, the BHL bibliographic or page number was added to that reference, thus creating a digital link improving access to the protologue. While undertaking this work we also collated a list of all those public domain publications that appeared to be absent from BHL. We passed on this list to BHL and requested these texts be scanned and added to BHL for the benefit of everyone.

We then added a named after statement to the Wikidata item for the appropriate plant genera linking that item to the Wikidata item for the woman honoured. Wikidata items for the women honoured were newly created or enriched. We researched each person and her contributions, plus information on mythological figures where necessary, and added this information to Wikidata items. Our work also included disambiguating the woman from other people with identical or similar names. 

To amplify the women’s contributions to science and to enrich the wider (biodiversity) data ecosystem, we linked to other Wikidata items and websites or databases by adding other relevant identifiers. For example if the women were botanists, botanical collectors or other naturalists, we used the author property to link the women to publications written by them. In addition, we added the women to Bionomia and attributed specimens collected or identified by them to their profiles.

Our work also included enriching Wikidata items of taxon authors. IPNI and Tropicos were searched for these author names, and websites such as BHL, the Global Biodiversity Information Facility (GBIF) or other specialist databases were consulted. Corrections or newly researched information on taxon authors was placed not just in Wikidata but was also sent together with the corresponding references to IPNI and Tropicos. This information was then used by those organizations to update these databases accordingly. 

As a result of our data being placed in Wikidata it is available to be queried via the Wikidata Query Service.  

Our Goal Achieved

As a result of our project, we published a dataset of 728 genera honouring women or female beings. This was a nearly twenty-fold increase in the number of genera linked to women in Wikidata. Our analysis paper on this data is forthcoming.

Notable Women 

Monsonia L.

All of us came away from this research with a favourite story. One that stood out was Ann Monson, for whom Linnaeus named Monsonia. Linnaeus wrote a delightful letter to her about their creating, platonically of course, a kind of plant love-child between them, in the form of this new genus.

Translated from Latin : “….Lock these [seeds] in a pot, and place them in the window of the chamber towards the sun, when it bursts forth in February, and in the first summer the sun blooms and lasts the most beautiful Alstromeria, which no one has seen in England, and you bring forth no flowers. If it should come to pass, as I wish, if you offer our flames, I would only wish to beget with you an only child, as a pledge of my love, little Monsonia, by which you may perpetuate the fame of Lady in the kingdom of Flora, who was the Queen of Women.”

Fittonia Coem.

Two eponymous women with an interesting story are Sarah Mary Fitton and her sister Elizabeth. They wrote Conversations on Botany in 1817 accompanied by colour engravings of flowers which popularised botany with women. The genus Fittonia was named in their honour.

Chanekia Lundell

Another woman honoured in a plant genus was Mercedes Chanek, a Mayan plant collector who worked in the 1930’s for Cyrus Longworth Lundell and collected for the University of Michigan in British Honduras, today Belize. Very little is known about her life and work. However, her collections are detailed in Tropicos and Bionomia, and you can see the genus named for her by Lundell in IPNI under Chanekia.

Medusa Lour. and other genera

Medusa (c. 1597), by Caravaggio

An example of a mythological female being honoured in several plant names is that of Medusa, who has the most genera named after her, six, more than any real woman!

We hope that our data paper inspires others to use the methodology and workflow described to create other linked open datasets, e.g. celebrating and amplifying the contributions of underrepresented or marginalised groups in science.
