Pensoft took a BiCIKL ride to Naturalis to report on a 3-year endeavour towards FAIR data

Three years ago, the BiCIKL consortium took to traverse obstacles to wider use and adoption of FAIR and linked biodiversity data.

Leiden – also known as the ‘City of Keys’ and the ‘City of Discoveries’ – was aptly chosen to host the third Empowering Biodiversity Research (EBR III) conference. The two-day conference – this time focusing on the utilisation of biodiversity data as a vehicle for biodiversity research to reach to Policy – was held in a no less fitting locality: the Naturalis Biodiversity Center.

On 25^thand 26^thMarch 2024, the delegates got the chance to learn more about the latest discoveries, trends and innovations from scientists, as well as various stakeholders, including representatives of policy-making bodies, research institutions and infrastructures. The conference also ran a poster session and a Biodiversity Informatics market, where scientists, research teams, project consortia, and providers of biodiversity research-related services and tools could showcase their work and meet like-minded professionals.

BiCIKL stops at the Naturalis Biodiversity Center

The main outcome of the BiCIKL project: the Biodiversity Knowledge Hub, a one-stop knowledge portal to interlinked and machine-readable FAIR data.

The famous for its bicycle friendliness country also made a suitable stop for BiCIKL (an acronym for the Biodiversity Community Integrated Knowledge Library): a project funded under the European Commission’s Horizon 2020 programme that aimed at triggering a culture change in the way users access, (re)use, publish and share biodiversity data. To do this, the BiCIKL consortium set off on a 3-year journey to build on the existing biodiversity data infrastructures, workflows, standards and the linkages between them.

Many of the people who have been involved in the project over the last three years could be seen all around the beautiful venue. Above all, Naturalis is itself one of the partnering institutions at BiCIKL. Then, on Tuesday, on behalf of the BiCIKL consortium and the project’s coordinator: the scientific publisher and technology innovator: Pensoft, Iva Boyadzhieva presented the work done within the project one month ahead of its official conclusion at the end of April.

As she talked about the way the BiCIKL consortium took to traverse obstacles to wider use and adoption of FAIR and linked biodiversity data, she focused on BiCIKL’s main outcome: the Biodiversity Knowledge Hub (BKH).

Key results from the BiCIKL project three years into its existence presented by Pensoft’s Iva Boyadzhieva at the EBR III conference.

Intended to act as a knowledge broker for users who wish to navigate and access sources of open and FAIR biodiversity data, guidelines, tools and services, in practicality, the BKH is a one-stop portal for understanding the complex but increasingly interconnected landscape of biodiversity research infrastructures in Europe and beyond. It collates information, guidelines, recommendations and best practices in usage of FAIR and linked biodiversity data, as well as a continuously expanded catalogue of compliant relevant services and tools.

At the core of the BKH is the FAIR Data Place (FDP), where users can familiarise themselves with each of the participating biodiversity infrastructures and network organisations, and also learn about the specific services they provide. There, anyone can explore various biodiversity data tools and services by browsing by their main data type, e.g. specimens, sequences, taxon names, literature.

While the project might be coming to an end, she pointed out, the BKH is here to stay as a navigation system in a universe of interconnected biodiversity research infrastructures.

To do this, not only will the partners continue to maintain it, but it will also remain open to any research infrastructure that wishes to feature its own tools and services compliant with the linked and FAIR data requirements set by the BiCIKL consortium.

On the event’s website you can access the BiCIKL’s slides presentation as presented at the EBR III conference.

What else was on at the EBR III?

Indisputably, the ‘hot’ topics at the EBR III were the novel technologies for remote and non-invasive, yet efficient biomonitoring; the utilisation of data and other input sourced by citizen scientists; as well as leveraging different types and sources of biodiversity data, in order to better inform decision-makers, but also future-proof the scientific knowledge we have collected and generated to date.

Project’s coordinator Dr Quentin Groom presents the B-Cubed’s approach towards standardised access to biodiversity data for the use of policy-making at the EBR III conference.

Amongst the other Horizon Europe projects presented at the EBR III conference was B-Cubed (Biodiversity Building Blocks for policy). On Monday, the project’s coordinator Dr Quentin Groom (Meise Botanic Garden) familiarised the conference participants with the project, which aims to standardise access to biodiversity data, in order to empower policymakers to proactively address the impacts of biodiversity change.

Dr France Gerard (UK Centre for Ecology & Hydrology) talks about the challenges in using raw data – including those provided by drones – to derive habitat condition metrics.

MAMBO: another Horizon Europe project where Pensoft has been contributing with expertise in science communication, dissemination and exploitation, was also an active participant at the event. An acronym for Modern Approaches to the Monitoring of BiOdiversity, MAMBO had its own session on Tuesday morning, where Dr Vincent Kalkman (Naturalis Biodiversity Center), Dr France Gerard (UK Centre for Ecology & Hydrology) and Prof. Toke Høye (Aarhus University) each took to the stage to demonstrate how modern technology developed within the project is to improve biodiversity and habitat monitoring. Learn more about MAMBO and Pensoft’s involvement in this blog post.

MAMBO’s project coordinator Prof. Toke T. Høye talked about smarter technologies for biodiversity monitoring, including camera traps able to count insects at a particular site.

The EBR III conference also saw a presentation – albeit remote – from Prof. Dr. Florian Leese (Dean at the University of Duisburg-Essen, Germany, and Editor-in-Chief at the Metabarcoding and Metagenomics journal), where he talked about the promise, but also the challenges for DNA-based methods to empower biodiversity monitoring.

Amongst the key tasks here, he pointed out, are the alignment of DNA-based methods with the Global Biodiversity Framework; central push and funding for standards and guidance; publication of data in portals that adhere to the best data practices and rules; and the mobilisation of existing resources such as the meteorological ones.

Prof. Dr. Florian Leese talked about the promise, but also the challenges for DNA-based methods to empower biodiversity monitoring. He also referred to the 2022 Forum Paper: “Introducing guidelines for publishing DNA-derived occurrence data through biodiversity data platforms” by R. Henrik Nilsson et al.

He also made a reference to the Forum Paper “Introducing guidelines for publishing DNA-derived occurrence data through biodiversity data platforms” by R. Henrik Nilsson et al., where the international team provided a brief rationale and an overview of guidelines targeting the principles and approaches of exposing DNA-derived occurrence data in the context of broader biodiversity data. In the study, published in the Metabarcoding and Metagenomics journal in 2022, they also introduced a living version of these guidelines, which continues to encourage feedback and interaction as new techniques and best practices emerge.

Exploring ‘sufficiency’: an overlooked strategy for protecting biodiversity?

Decision makers are urged to re-evaluate their priorities.

A study from the Technical University Berlin suggests ‘sufficiency’ should be a more prominent strategy for protecting biodiversity.

Published in the open-access journal Nature Conservation, the paper analyses the intersection between biodiversity conservation and sufficiency strategies aimed at reducing consumption and resource use.

Study author Marianne Hachtmann notes that despite the established connection between excessive resource use by humans and biodiversity loss, there is limited explicit focus on how sufficiency strategies can support biodiversity preservation.

Reviewing literature from 2017 to 2021 and publications by nature conservation associations, the research identifies a notable gap in discussions linking sufficiency directly with biodiversity outcomes. Possible reasons for this may be the term’s political implications, lack of descriptiveness, and the use of other terms.

Methodology diagram — Research methodology

Furthermore, the lack of connection between sufficiency and biodiversity could be because they belong to different ‘scientific spheres’. Linking the two terms thus requires a reflective, interdisciplinary perspective.

The study proposes a detailed sufficiency typology to foster a systematic approach towards integrating the term in biodiversity conservation efforts.

“The sufficiency typology developed here allows for a systematic integration of sufficiency into biodiversity conservation and thus a joint consideration of social and nature conservation concerns.”
Marianne Hachtmann, Technical University Berlin

Policymakers, conservationists, and researchers are urged to prioritise sufficiency for the broader strategy for biodiversity conservation and sustainable living. The paper calls for further investigation into how sufficiency strategies can be crucial in conserving biodiversity and promoting sustainability.

Melting glaciers provide new ground for invasive species

A case study on the island of South Georgia.

Invasive species spread through human activities are one of the main causes of the ongoing biodiversity crisis.

Even on South Georgia, a remote island located in the very south of the Atlantic Ocean, exotic species are present. Many of which were inadvertently introduced by whalers and sealers in the 19^th and early 20^th century.

The invasive carabid ground beetle, Merizodus soledadinus, is present on sites that have been recently exposed by melting glaciers.

In a new study published in the open-access journal Neobiota and funded by Darwin Plus, researchers explored how living organisms colonise new ground provided by melting glaciers.

Like other cold regions of the world, South Georgia is losing its glaciers because of climate change, leaving behind large areas of newly uncovered bare ground.

Invasive annual meadow grass colonising ground only a few years after the glacier disappeared.

Researchers surveyed the foreland biodiversity of six glaciers, creating an inventory of the flora and fauna that colonise forelands at different stages of glacial retreat.

A survey site near a former whaling station (Grytviken).

They found that, just a few years after bare ground is exposed by a glacier melting, pioneer plants arrive, progressively covering more ground with time, followed by an increasing number of species.

Native and exotic plants, as well as invertebrates, take advantage of this opportunity. Surprisingly, two temperate plant species from the Northern Hemisphere, annual meadow grass and mouse-ear chickweed, colonise sites faster than any other species.

The team suggests their results indicate invasive species will likely spread on South Georgia as fast as glaciers are retreating. Whether this has or will have negative consequences on local species needs to be investigated to help protect this unique ecosystem.

Orchard meadows: reviving Europe’s forgotten landscapes

Researchers call for political and public support to protect these areas.

A study spearheaded by researchers at the Helmholtz Centre for Environmental Research and Macquarie University has highlighted the important ecological role of traditional orchard meadows, calling for political and public support and incentives for farmers to protect these landscapes.

The paper, published in the open-access journal Nature Conservation, reviews the effects of management, habitat and landscape characteristics on the biodiversity of these areas in Central Europe.

Orchard meadow management graphic. — Schematic figure illustrating the effects of management intensification on species richness. The graph illustrates the potential effect of management intensity (from high over intermediate to abandonment/rewilding) on species richness in orchard meadows.

Orchard meadows, characterised by the combination of cultivated grasslands and scattered fruit trees, exhibit high flora and fauna biodiversity. Despite their ecological value, these habitats have been in decline since the mid-19th century due their decreasing economic worth. They now face threats from land abandonment and intensification of agriculture.

The study emphasises the importance of moderate management intensity, connectivity to neighbouring habitats, and the preservation of structural diversity to maintain and enhance the conservation value of orchard meadows. The findings also advocate for a nuanced understanding of management impacts across taxonomic groups and points out the limitation of available studies on these habitats in Central Europe.

Currently loose in definition, the research team advocated for a clear definition of orchard meadows to create a common term in Europe, which would make their assessment and protection more straightforward. They suggest orchard meadows should be listed in the Habitats Directive of the Council of the European Union and farmers should get incentives for their maintenance. Finally, the research team calls for political and public support to prevent the loss and abandonment of these biodiverse landscapes.

“One way the public support the protection of these habitats is through consumer behaviour, specifically by purchasing local products from orchard meadows. However, it is crucial to subsidise these local products and prioritize them at local markets.

“As long as fruits from orchard meadows are treated as ‘by-products’ in the market, it will be challenging to convince people to buy local products. This change is necessary to close the economic gap between intensified fruit production and extensive orchard meadows.”
Cornelia Sattler, lead author.

Discovering Van Gogh in the wild: scientists unveil a new gecko species

Males of the species have a yellow head and forebody and light blue spots on the back and they live in low elevation forests of the Southern Western Ghats.

You’ve probably seen nature depicted in art, but how often do you see an artwork hiding in nature?

When they saw the back of a lizard in the Southern Western Ghats, a group of scientists from the Thackeray Wildlife Foundation in India were reminded of Van Gogh’s The Starry Night. As soon as they figured out it was a new species, it was only apt to name it in honour of the famous painter.

“Cnemaspis vangoghi is named for Dutch painter Vincent Van Gogh (1853–1890) as the striking colouration of the new species is reminiscent of one of his most iconic paintings, The Starry Night,” explains Ishan Agarwal, who took part in the study to describe the new lizard. Males of the species have a yellow head and forebody and light blue spots on the back and they live among rocks and occasionally buildings and trees.

Together with his fellow researchers Akshay Khandekar and Tejas Thackeray, they found the new species during an expedition in April 2022 to the the Southern Western Ghats in Tamil Nadu, India. Now, they have published their findings in the peer-reviewed journal ZooKeys.

“Tamil Nadu is an exceptionally biodiverse state and we expect to name well over 50 new species of lizards by the time we are done [with our expeditions]!,” Ishan Agarwal says.

“I also had more than 500 tick bites during that summer trip, with the highest densities in the low-elevation, dry forests of Srivilliputhur, where the new species are found,” he adds.

Cnemaspis vangoghi is a small-sized gecko that can reach 3,4 cm in length. It was described as new to science together with another species of its genus, Cnemaspis sathuragiriensis, named for its type locality the Sathuragiri Hills.

“The two new species are distributed in low elevation (250–400 m asl.), deciduous forests of Srivilliputhur, and add to the five previously known endemic vertebrates from Srivilliputhur-Megamalai Tiger Reserve, Tamil Nadu, India,” Ishan Agarwal explains. They are diurnal and mainly active during the cool hours of the early morning and evening, found largely on rocks. So far, they have only been found in very restricted localities, “an interesting case of micro-endemism in low-elevation species,” he notes.

Rare bee species discovery links the French Alps to Turkey and Iraq

The new species has a narrow ecological niche, making it vulnerable to climate change and agricultural practices.

European researchers have discovered a new species of osmiine bee with an unusual geographic distribution.

Hoplitis onosmaevae is currently found exclusively in the Mercantour National Park in the French Alps and disparate mountainous regions in Turkey and Northern Iraq. The distance of more than 2000 km between these areas highlights a significant biogeographic disjunction.

New bee species distribution. — Distribution map of *Hoplitis* *onosmaevae*.

Described in the open-access journal Alpine Entomology, the new bee species demonstrates unique ecological characteristics such as its distinct nesting behaviour in dead wood.

Presumed to only harvest pollen from Onosma species, it has a long proboscis, which is likely an adaptation to collect nectar from the long-tubed flowers of this genus.

The strongly disjunct distribution of Hoplitis onosmaevae has important implications for conservation. The species likely has a very narrow ecological niche, making it highly susceptible to future changes in its habitats, for example due to changes in agricultural practices or to climate change.

New bee species habitat. — Nesting habitat in the Alps, with dead trunks of larch.

New bee species in flower. — Female *Hoplitis* *onosmaevae* in a flower of *Onosma tricerosperma*.

“The consideration of the few known populations of this species in France is very important in the conservation field,” says lead author Matthieu Aubert, freelance entomologist and member of the Observatoire des Abeilles association.

“This study highlights the incredible diversity of wild bees and that we still have a lot to learn from our environment, even in western Europe,” he continues.

The researchers emphasise the need for detailed conservation plans in the southwestern Alps to ensure the survival of Hoplitis onosmaevae, considering its highly specialised ecological niche and consequently its vulnerability to habitat changes. Their proposals for initial conservation steps can be found in the full research paper.

“Tiny, beautiful, and completely unknown animals”: Citizen scientists discover new beetles from the Borneo forest

The field trip allowed laypeople to participate in the study of biodiversity, and to discover and name a new species.

The undiscovered small beetles in the tropical rainforest are probably endless. But that did not discourage citizen scientists on expeditions to the Ulu Temburong forest in Borneo to keep adding them to scientific records, one at a time. Together with a team of researchers, they published a new species, Clavicornaltica mataikanensis in the open-access peer-reviewed Biodiversity Data Journal.

The minute, two-mm-long leaf beetle that lives on the forest floor is the latest discovery of Taxon Expeditions, which organises scientific field trips for teams consisting of both scientists and lay people. Unlike other science/adventure trips, Taxon Expeditions organises real scientific expeditions for lay people, guiding them in the discovery of new species of animals, by focusing on the thousands of ‘little things that run the world’.

Clavicornaltica mataikanensis, named for the stream Mata Ikan (“fish eye”) that runs in the valley where it was found, is one of a plethora of tiny beetle species that live in the leaf litter of tropical forests—and most of them have not yet been scientifically described and named. At 2 mm long, the flea beetle is actually one of the largest among its relatives – which might explain why so little is known about their ecology and diversity.

The field trip, in which local students and researchers also took part, gave untrained lay people the opportunity to participate in the study of this hidden world of biodiversity and in the process of naming and publishing new species. Participant Lehman Ellis, from the US, says it was “exciting and beautiful” to be part of the discovery.

Providing solutions to restoring the natural water retention function of landscapes: Pensoft joins the SpongeBoost project

At SpongeBoost, Pensoft is to take charge of the project’s identity, while building a strong network, and providing comprehensive knowledge and well-packaged information.

In recent years, Europe’s landscapes have become the victims of extreme events – ranging from floods to droughts – that have caused considerable damage to nature as well as human society.

With the aim to tackle such severe circumstances, the newly-started Horizon Europe-funded project SpongeBoost will be working towards protecting and promoting natural sponge landscapes.

Within SpongeBoost, the functional capacity of sponge landscapes is to be enhanced through building upon existing solutions and their large-scale implementation, but also through innovative approaches.

Pensoft is among the partnering institutions within SpongeBoost and serves as the leader of Work Package #5: “Communication, dissemination, exploitation, showcasing best practices and networking”. WP5 will aim to contribute to the project’s mission by building the overall project identity, building a strong network, and providing comprehensive knowledge and well-packaged information to targeted stakeholders.

The project

Funded by the European Union’s Horizon Europe research and innovation programme with a budget of EUR ~3 million, the project is coordinated by the Helmholtz Centre for Environmental Research (UFZ) and will be developed with the active participation of 10 partnering institutions from seven countries across Europe. Having been officially launched in January 2024, SpongeBoost is to wrap up in December 2027.

The project is part of the EU mission “Adaptation to Climate Change”, whose task is to support EU regions, cities and local authorities in their efforts to build resilience against the impacts of climate change.

“The protection and revitalisation of wetlands, particularly through peatland rewetting and river floodplain restoration, plays a central role in this,“
says project manager Mathias Scholz from the UFZ.

SpongeBoost held its official kick-off meeting in late February (2024) in Leipzig, Germany.

To officially kickstart the project, the first consortium meeting took place on 21-23 February in Leipzig, Germany. The kick-off meeting saw all 10 partnering institutions meet in person to officially lay the foundation of a promising collaboration that will flourish over the next four years.

The joint mission before the newly formed consortium is to enhance the natural sponge function of wetlands and soils in Europe, aligning with EU policies for climate adaptation, disaster risk reduction and biodiversity. To achieve that, the project plans to employ both bottom-up and top-down approaches, which will foster networking and synergy at the regional and EU level.

SpongeBoost will focus on five main objectives over the next four years:

Conduct a comprehensive literature review to create a standard reference catalogue for securing and enhancing sponge functions in adaptation to climate change. This catalogue will integrate social, economic, technical, and ecological effects and serve as a widely used resource across Europe and beyond.

Build a knowledge base on existing approaches for enhancing sponge functions, and highlight the reasons for success or failure. The goal is to enable regions and communities to replicate effective transformative solutions. Meanwhile, the consortium is to facilitate networking initiatives with other projects and identify suitable pilot sites for monitoring long-term success using the results of previous projects.

Work on the implementation, tests, refinement, and adjustment of best practices and innovative solutions through EU-wide case studies. The goal is to enhance climate resilience to extreme events and enable upscaling from local to EU levels.

Develop a roadmap with practical tools to empower stakeholders, drive transformative change, and integrate sponge solutions into regional, national and European climate adaptation processes to achieve EU Green Deal targets.

Connect communities and compile online resources for climate change adaptation. The goal is to facilitate access and combine a library of tools for restoration and share research findings on soil, water, and groundwater interconnection for replication across Europe.

In addition to leading the “Communication, dissemination, exploitation, showcasing best practices and networking” work package at SpongeBoost, Pensoft is to also assist the Environmental Action Germany (DUH) in the implementation of different innovative communications methods and ideas meant to support the project’s goals.

As part of the creative communication strategy, DUH will take the lead in the development of a “SpongeBooster superhero” character. By creating such a character that will be also featured in comics, the team will translate complex concepts into clear visuals and engaging narratives, thereby shaping the project’s visual identity and letting non-experts join the discourse. The Sponge Booster is to serve as an innovative method to disseminate project knowledge and address barriers with humour while fostering dialogue and avoiding potential conflicts.

International Consortium

The SpongeBoost project brings together a team of 10 partners from seven European countries, spanning research, policy, and management fields. The consortium members, who individually represent various restoration projects, will join forces and expertise to promote collaboration, knowledge exchange and synergies across European regions, to ultimately instil a lasting positive impact on sponge restoration for climate change adaptation.

Eyes open and toes out of water: how a giant water bug reached the island of Cyprus

A new visitor was reported on the coast of Cyprus, thanks to the growing power of citizen science.

The island of Cyprus, although considered a hotspot for biodiversity in the Mediterranean, is more famous for its beautiful sunny coasts than for its insect fauna. Nevertheless, some visitors of its highly populated beaches, with their observations and curiosity, have provided important information for a species never recorded before on the island: a giant water bug, also known as a toe biter.

Scientists Michael Hadjiconstantis from the Association for the Protection of Natural Heritage and Biodiversity of Cyprus, Iakovos Tziortzis from the Ministry of Agriculture, Rural Development and Environment of Cyprus, and Kadir Boğaç Kunt from the Cyprus Wildlife Research Institute collected information and specimens from an increasing number of records of the giant water bug on the east coastline of the island in late spring and summer of 2020 and 2021. The species, known for inhabiting ponds and slowly moving freshwaters, had never been recorded on the island before, although established populations are known in adjacent Mediterranean countries such as Greece, Turkey, and Israel.

Locations of the reported Giant water bug sightings in Cyprus.

Also referred to as Electric light bug, this giant water bug is described as a vicious hunter, praying on invertebrates, fish, turtles, and even birds. What is even scarier, as the largest European true bug and the largest European water insect and measuring up to 12 cm, it has a reputation of inflicting very painful bites when handled carelessly.

Its appearance, mainly on the eastern coastal front of the island, was initially recorded by swimmers, who were surprised by the fearsome looks and size of the bug. They either directly contacted the experts or published photos and videos online, mainly on Facebook groups related to biodiversity. The authors collected some of the specimens for further study. They also proceeded with an extensive online search on relevant online observation platforms (i.e. iNaturalist) in order to track any other reports of the species on the island. In addition, they sampled nearby wetlands, but did not spot the bug. End to end, a total of seven sightings were eventually recorded: five from social media and two after direct communication with the author team. Two specimens were obtained and examined morphologically to verify the species. The observations were recorded in a research article in the open-access journal Travaux du Muséum National d’Histoire Naturelle “Grigore Antipa”.

Having in mind that the toe biter is an iconic species accompanied by creepy stories concerning its encounters with humans, the authors assume that it is unlikely that it had gone unnoticed for too long. They consider it possible that several migration events might have been triggered in a short period of time by nearby countries hosting the species, such as Israel, Lebanon, and Syria. The specimens could have been transferred by wind or sea currents, as assumed by other researchers, or could have been driven by a decrease in food resources in their initial area of distribution.

Despite the number of recordings in a short timeframe, no conclusions can be drawn for the moment on the establishment of a population of the species on the island. This is further to be investigated, and as the initial recording of the species, citizen science can have an important role in this. The authors urge the public to be alert: “Naturalists looking for alien-like critters can provide valuable information on the presence and a possible establishment of the species through citizen science.” Until then, they warn: “Cypriots should keep their eyes open and their toes out of the water”.

Ocean treasures: Two new species from ZooKeys highlighted by WoRMS

Two of 2023’s top marine species were first introduced to the scientific world on the pages of our journal ZooKeys.

Where would we be without taxonomists? We wouldn’t even want to imagine such a scenario, even though experts in taxonomy are declining at an alarming rate, just like some of the threatened species they describe.

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

This Taxonomist Appreciation Day is a great excuse to marvel at the amazing species that biodiversity specialists continue describing across the globe. The World Register of Marine Species does that by publishing a selection of the top 10 marine species published each year – we’re proud to share with you that two of 2023’s top marine species were first introduced to the scientific world on the pages of our journal ZooKeys!

One of them is Tetranemertes bifrost, a beautiful ribbon worm from the Carribean whose description was published in ZooKeys.

The most spectacularly colored nemertean in the Caribbean, if not the world, it has a long, thin, thread-like body that can stretch much more than 200 mm long. Its head has a characteristic, narrow diamond or spearhead shape, vaguely reminiscent of a viper’s head.

Its name refers to the bright, colorful iridescent stripes and spots characterizing it. Bifrost, the rainbow bridge in the Norse mythology, reaches between Midgard, the human Earth, and Asgard, the realm of the gods. Some authors state that the name Bifrost means “shimmering path” or “the swaying road to heaven”, and that it might be inspired by the Milky Way.

This benthic marine worm usually lives in coral rubble, gravel, and shell hash. It can often be found stretched between nooks and crannies of the substratum.

Found near Bocas del Toro, Panamá, it is one of the first records of this genus in the Carribean sea.

In the 1970s, some 50 years before it was scientifically described, Smithsonian photographer Kjell Sandved took a picture of it draped over an unknown fan coral off Puerto Rico.

The second ZooKeys species featured in the selection is the whimsical Nautilus samoaensis.

Nautiloids were in fact quite plentiful throughout the oceans at one point, based upon the fossil record. Today, they are represented by just a handful of species. Nautilus samoaensis and two other species got described as new to science in ZooKeys in early 2023, proving that Nautilus are more diverse than one could think.

Nautilus samoaensis has a beautiful shell; in fact, its shell color pattern is the most unique of all Nautilus species. It is composed of multiple, branching stripes that have a rearward projection after descending from the venter. No other known Nautilus species shows this color pattern. It lives near Pago Pago, American Samoa, where it has been found at depths between 200 and 400 m.

This marine species also ranked second in Pensoft’s Top 10 New Species selection for 2023.
