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.
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!
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.
Last year, we told you about the peculiarities of studying nautilus species, but these animals are actually under a serious threat from illegal fishing, as they are highly prized for their shells.
The Top 10 Marine Species is an initiative that brings awareness to the importance of the work of biodiversity scholars, so announcing it on Taxonomist Appreciation Day is only fitting; but it also highlights the need to better protect our oceans and the unique life that hides in there.
In 2023, the world of biodiversity saw some amazing discoveries . Our taxonomy journals published hundreds of new species, so selecting a Top Ten was tough, but here we go – get to know these beautiful new species, and maybe think about all the amazing diversity that still remains unexplored on our planet.
10. The walking leaf
It’s very often that undescribed species hide in plain sight for years, but it’s easy to understand why when they look like that! Leaf insects look confusingly similar to leaves – this sophisticated camouflage provides excellent protection from predators, but also presents a challenge to researchers.
“There are around 3,500 known species of stick and leaf insects and there are currently just over 100 described species of leaf insect,” researcher Dr Sven Bradler says. This is why when Phyllium ortizi and six other leaf insect species were found, it made for a really special discovery.
Lime-green in colour, Phyllium ortizi is so far only known from Mindanao Island, Philippines.
The Eastern Forest Hedgehog (Mesechinus orientalis) was discovered in southwestern China. It is a small-bodied hedgehog, smaller than most of the other species in its genus, its spines as short as 1.8-2 cm. It has a brown nose, with black whiskers that shorten towards the nose.
The species is currently known from southern Anhui and northwestern Zhejiang, where it lives in scrubland and subtropical broad-leaf evergreen forests at elevations from 30 to 700 m.
The researchers found out that genus Mesechinus, to which the new species belongs, dates back to the early Pleistocene and started appearing around 1.71 million years ago, while M. Orientalis diverged from its congeners some 1.1 million years ago.

8. The bumpy salamander
Tylototriton zaimengwas found in the eponymous Zaimeng lake in Manipur, India. It is a medium-sized salamander has a massive wide head that could take up as much as a quarter of its total length. Its most distinctive feature are the knob-like warts along its body.
The salamander has an earthy-brown body with orange markings along its head and orange-brown warts down its back and sides. Its tail fades from brown at the base to yellow-orange at the tip.
Even though it has just been discovered as a species for science, locals know a lot about it and have different names for it.
Because its known range is limited and threatened by deforestation and human interference, the species should be considered vulnerable.
An unexpected discovery, this new treefrog species was found in the Amazon lowlands of central Peru. The research team, led by Germán Chávez, was surprised that a new species could be hiding in plain sight in an otherwise well-explored part of the Amazon. No matter how many times they returned to the site, they only found two specimens, which made its scientific description challenging.
Its name, Scinax pyroinguinis, literally means “groins of fire”. It is a reference to the orange, flame-like pattern on the groins, thighs and shanks, but also to the wildfires in the area where it was found, which are a serious threat to its habitat.
Pinguicula ombrophila is part of the butterwort family, a group of insectivorous flowering plants consisting of around 115 species. Its leaves have a sticky texture, enabling it to capture and digest small insects.
For carnivorous plants, insects can be an additional source of nutrients to help them compensate the nutrient deficiency of the substrate they’re growing in. This gives them a competitive advantage over other plants and enables them to thrive in challenging habitats.
While the majority of butterworts are found in the northern hemisphere, this species was discovered in the elevated regions of southern Ecuador, near the Peru border. The research team found it on a nearly vertical rock face at 2,900 metres. Its name means “rain-loving butterwort”, highlighting the plant’s preference for very wet conditions.
Sinocyclocheilus longicornus(from the Latin words “longus”, meaning long, and “cornu”, meaning horn) comes from Southern China. It is only known from a dark vertical cave at an elevation of 2,276 m in the province of Guizhou. It is around 10-15 centimeters long and lacks pigmentation in its scales, which gives it it a ghostly whitish appearance. Since its eyes are small and probably not much help in a completely dark environment, it relies on barbels that look like tiny whiskers to feel its way around.
The researchers that found it are not quite sure what its “horn” is used for, but it might have something to do with navigating its way in the dark and dreary environment it inhabits.
Sinocyclocheilus longicornus is also featured in the SHOALS report on freshwater fish species described in 2023.
Sibon irmelindicaprioae was described as a new species together with four more tree-dwelling snake species from jungles of Ecuador, Colombia, and Panama. They all belong to Dipsadinae —a subfamily of snakes found in North and South America.
Also known as DiCaprio’s snail-eating snake, this species was named after actor and film producer Leonardo DiCaprio’s mother, Irmelin DiCaprio. The actor himself chose the name to honour his mother and raise awareness about the threats these snakes face.
Its habitat in Panama is affected by large-scale copper mining. The open-pit mines, some of them visible from space, make the areas uninhabitable for snail-eating snakes.
“These new species of snake are just the tip of the iceberg in terms of new species discoveries in this region, but if illegal mining continues at this rate, there may not be an opportunity to make any future discoveries,” says Alejandro Arteaga, who led the study to describe them.

3. The Tolkien frog
You probably guessed it by now – this stream frog from the Ecuadorian Andes was named after J.R.R. Tolkien, the author of The Hobbit and The Lord of the Rings.
At about 66 millimeters (2.5 inches) long, Hyloscirtus tolkieniis tiny enough to fit in the palm of your hand, but that doesn’t stop it from being simply stunning. With pale pink eyes and gold-speckled toes, it looks like it came straight out of Middle-earth. It was found at an elevation of 3190 meters in Río Negro-Sopladora National Park, a protected area of páramo and cloud forests.
“The new species of frog has amazing colours, and it would seem that it lives in a universe of fantasies, like those created by Tolkien. The truth is that the tropical Andes are magical ecosystems where some of the most wonderful species of flora, funga, and fauna in the world are present. Unfortunately, few areas are well protected from the negative impacts caused by humans. Deforestation, unsustainable agricultural expansion, mining, invasive species, and climate changes are seriously affecting Andean biodiversity”, said Diego F. Cisneros-Heredia, one of the researchers behind this discovery.

2. The enigmatic Nautilus
2023 was a great year for nautilus biodiversity: three species were described as new to science, including Nautilus samoaensis, which you see here. Like its name tells you, it was found off the coast of American Samoa.
Studying nautilus diversity is no easy feat – with setting spiky traps, hauling them over on board, and, eventually, burping nautiluses, it is surely a memorable experience.
Judging by the fossil record, nautiloids were once quite plentiful throughout the oceans. Today, however, they are represented by just a handful of species.
In addition, these fragile animals remain threatened by wildlife trade as they are hunted for their shells, which according to Mongabay can sell for up to about $1,000 each on the black market.
Found in Thailand’s Phang-Nga province, Chilobrachys natanicharum features an enchanting phenomenon: a neon blue-purple coloration that gives it a unique look.
There is no blue pigment in this tarantula’s body: the secret behind its striking color comes from the unique structure of its hair, which incorporates nanostructures that manipulate light in an effect that creates the blue appearance. Depending on the light, it can also appear violet.
Before it was described as a new species, Chilobrachys natanicharum was actually known to experts from the commercial tarantula trade market as “Chilobrachys sp. Electric Blue Tarantula,” but this is the first time that it’s discovered in its natural habitat.
Its name, in fact, resulted from an auction campaign, the proceeds from the auction have been channeled to bolster the education of Lahu children in Thailand and to aid impoverished cancer patients.
Pensoft will lead the communication, dissemination and exploitation activities of the Horizon Europe project, which aims to reverse pollinator population declines and reduce impacts of pesticides.
Plant protection products (PPP), also known as pesticides, have been identified as one of the primary triggers of pollinator decline. However, significant knowledge gaps and critical procedural limitations to current pesticide risk assessment require attention before meaningful improvements can be realised. The functional group is currently represented by only one species, the honey bee, which does not necessarily share other species’ biological and ecological traits.
Coordinated by The Social-Ecological Systems Simulation (SESS) Centre, Aarhus University and Prof. Christopher J. Topping, PollinERA (Understanding pesticide-Pollinator interactions to support EU Environmental Risk Assessment and policy) aims to move the evaluation of the risk and impacts of pesticides and suggestions for mitigationbeyond the current situation of assessing single pesticides in isolation on honey bees to an ecologically consistent assessment of effects on insect pollinators.
This will be achieved through the development of a new systems-based environmental risk assessment (ERA) scheme, tools and protocols for a broad range of toxicological testing, feeding to in silico models (QSARS, toxicokinetic/toxicodynamic, and ALMaSS agent-based population simulations).
The One System framework builds on the recent roadmap for action on the ERA of chemicals for insect pollinators, developed within the IPol‐ERA project, funded by the European Food Safety Authority (EFSA). The framework will expand the ERA tools currently used for honey bees to include wild bees, butterflies, moths and hoverflies.
Fill ecotoxicological data gaps to enable realistic prediction of the source and routes of exposure and the impact of pesticides on pollinators and their sensitivity to individual pesticides and mixtures.
Develop and test a co-monitoring scheme for pesticides and pollinators across European cropping systems and landscapes, developing risk indicators and exposure information.
Develop models for predicting pesticide toxicological effects on pollinators for chemicals and organisms, improve toxicokinetic/toxicodynamic (TKTD) and population models, and predict environment fate.
Develop a population-level systems-based approach to risk and policy assessment considering multiple stressors and long-term spatiotemporal dynamics at a landscape scale and generate an open database for pollinator/pesticide data and tools.
With more than 20 years of experience in science communication, Pensoft is leading Work Package 6: Communication, Dissemination and Exploitation, that will ensure the effective outreach of PollinERA to its multiple target audiences. Based on the tailor-made communication, dissemination, exploitation and engagement strategies, Pensoft will provide a recognisable visual identity of the project, along with a user-friendly website, social media profiles, promotional materials, newsletters, infographics and videos. Pensoft will also contribute to the stakeholder mapping process and the organisation of various workshops and events.
Coordinated by Prof. Denis Michez (University of Mons), WildPosh aims to significantly improve the evaluation of risk to pesticide exposure of wild pollinators, and enhance the sustainable health of pollinators and pollination services in Europe.
The PollinERA consortium comprises partners from eight European countries that represent a diverse range of scientific disciplines spanning from pollinator ecology, pesticide exposure and toxicological testing, to stakeholder engagement and communications.
Conservationists have initiated breeding programmes in Vietnam to recover spotted softshell turtle populations threatened by overconsumption and habitat loss.
Based on a literature study, field surveys across Vietnam, and genetic screenings of collected samples, researchers estimated the range and conservation status of Pelodiscus variegatus, the spotted softshell turtle. The data were then used to model the species’ potential range in Vietnam.
Alarmingly, although several protected areas in Vietnam appear to harbour suitable habitats for the species, no populations were identified in any of the sites, indicating it is especially susceptible to extinction.
To recover natural populations of the species, the Institute of Ecology and Biological Resources and Cologne Zoo, Germany, initiated an in-country breeding programme. In late 2023, they released 50 young and healthy turtles to a site with suitable climate and habitat in northern Vietnam.
It is hoped that additional individuals will be reintroduced to protected areas in north-central Vietnam, the sanctuary of spotted softshell turtles, to reverse its declining trend and further contribute to the global Reverse the Red movement, a target best accomplished by applying the IUCN’s One Plan Approach to Conservation.
Softshell turtles of the genus Pelodiscus are broadly distributed from southeastern Siberia through China to Vietnam. However, their range is currently extended to Indonesia, northern Australia, western Europe, North America, Hawaii, and Mauritius as a result of human transportation and breeding activities.
The turtles are considered a delicacy in China and some Southeast Asian countries. In China alone, each year hundreds of million turtles are traded, making them the most widely consumed turtles in the world.
Traditionally, this genus had been considered monotypic with only one recognised species, the Chinese softshell turtle (Pelodiscus sinensis). However, recent research has shown that the genus is much more diverse with at least seven species known to science.
Due to their morphological similarity, widespread farming activities, overharvesting, and their aquatic lifestyle, it is often difficult to study them in their natural habitat to better understand their distribution as well as their population and conservation status.
Like other congeners, the spotted softshell turtle is facing tremendous threats, from habitat loss to overharvesting for food and genetic pollution because the Chinese softshell turtle has been farmed across the country, imperilling the native genetic sources.
As the result, the Turtle Taxonomy Working Group, the global authority on taxonomic and conservation status of turtles worldwide, provisionally classifies the species as Critically Endangered, the highest ranking for taxa most vulnerable to extinction.

As a leader of the Work Package 6: “Dissemination, Multi-stakeholder outreach and synergies,” Pensoft is tasked to build an involved community around OBSGESSION.
Pensoft is to contribute to the OBSGESSION consortium with expertise in science communication by taking care of stakeholders engagement, thereby supporting its goal of improved terrestrial and freshwater biodiversity monitoring. As a leader of the Work Package 6: “Dissemination, Multi-stakeholder outreach and synergies,” Pensoft is tasked to build an involved community around OBSGESSION.
Terrestrial and freshwater biodiversity has been declining at an alarming rate due various factors such as intensification of anthropogenic activities and climate change.
Coordinated by the Finnish Environmental Institute (Syke), OBSGESSION aims to reveal the drivers of biodiversity loss, pinpoint important indicators of ecosystem health and inform sustainability policy.
The project officially kicked off with the first consortium meeting in Tuusula, Finland, between 30th January and 2nd February.
For the coming four years, the joint mission before the newly formed consortium is to integrate biodiversity data sources, such as Earth Observation, with in-situ research, and also cutting-edge ecological models. These will all be made into a comprehensive product for biodiversity management in both terrestrial and freshwater ecosystems.
The project will also spearhead an innovative approach for assessing Essential Biodiversity Variables (EBVs) and their resilience to errors. Through purposely propagating error into biodiversity estimates and comparing the resulting models with ones using correct estimates, the EBV case studies aim to investigate model uncertainties and identify approaches that are more sensitive. Thus, they will inform policy and management about the optimal EBVs, and their key thresholds for conservation.
To demonstrate the implementation of the techniques and methodologies they are to develop within the project; and to respond to the needs of the EU Biodiversity Strategy for 2030, the consortium will focus on six distinct pilot activities:
Investigating and predicting biodiversity change in the European Alps: multi-scale, multi-modal and multi-temporal investigation using remote and in-situ data integration.
Improving habitat classification models: going beyond state-of-the-art in terms of accurate high-resolution mapping of Europe’s habitats, powered by machine learning.
Forecasting ecosystem productivity under disturbances & climate change:incorporating remote sensing EBVs to assess metrics of ecosystem structure and health.
Supporting temperate and boreal forest protection & restoration: through assessing ecosystem conditions via eDNA & image spectroscopy.
Monitoring freshwater ecosystems under disturbances & climate change: utilizing the novel Thematic Ecosystem Change Indices (TECIs).
Ecosystem functioning of the Kokemäenjoki estuary – assessing freshwater & transitional water quality incorporating both in-situ and Earth Observation data.
Through its pilot studies, methodological assessments, data stream integration, and investigating land use cover changes across Europe, OBSGESSION will help improve our understanding of ecosystem vulnerability across a range of specific habitat types, identify driversand pressures to ecosystem change and improve planning and prioritization of restoration measures.
International Consortium
The interdisciplinary OBSGESSION consortium consists of 11 partnering organisations from seven European countries, who bring diverse expertise spanning from remote sensing and Earth observation, to freshwater ecosystems, programming and science communication. Many partners represent acclaimed scientific institutions with rich experience in collaborative EU projects.
The indexing is one of the major outcomes from the partnerships within the Horizon 2020-funded project Biodiversity Community Integrated Knowledge Library (BiCIKL)
In a joint effort between the Swiss-based Text Mining group of Patrick Ruch at SIB (developing SIBiLS), the text- and data-mining association Plazi and scientific publisher Pensoft, the long-time collaborators have started feeding full-text content of over 500,000 taxonomic treatments extracted by Plazi and tens of thousands full-text articles from 40 well-renowned biodiversity journals published by Pensoft to the SIBiLS database.
What this means is that users at SIBiLS – be it human or AI – have now gained access to advanced text- and data-mining tools, including AI-powered factoid question-answering capacities, to query all this full-text indexed content and seek out, for example, species traits and biotic interactions.
To index and directly feed the content from its 40+ academic outlets at SIBiLS, Pensoft relies on advanced and full-text TaxPub JATS XML journal publication workflow, powered by the ARPHA publishing platform. Meanwhile, Plazi uses its GoldenGate text- and data-mining software to harvest taxon treatments from over 80 journals stored at TreatmentBank and the Biodiversity Literature Repository, and then further re-used by GBIF, OpenBiodiv and now by SiBILS.
Seen as a pilot, the indexing – the partners believe – could soon be extended with other journals relying on modern publishing or converted legacy publications.
However, there were still gaps left to bridge before SIBiLS could indeed be dubbed “the Biodiversity PMC”, and those have mostly been about volume and breadth of content. While the above-mentioned five journals by Pensoft had long been indexed by SIBiLS through harvesting PMC, those had been quite an exception since, several years ago, a reorganisation at PMC moved the focus of the database to almost exclusively biomedical content, thus leaving biodiversity journals out of the scope of the database.
In the meantime, while Plazi has been feeding SIBiLS a growing volume of taxonomic treatments and visual data, as it was exponentially increasing the number of publishers and journals it mined data from, a lot of biodiversity data (e.g. genetic, molecular, ecological) published in the article narratives that were not taxon treatments could not make it to the portal.
“For far too long, scientific knowledge about biodiversity has been imprisoned in a continuously growing corpus of scientific outputs, which – most of the time – are published in unstructured formats, such as PDF, or as paywalled content, and often locked by both! This means that they are – at best – difficult to access and comprehend by computer algorithms. In the meantime, we need all that knowledge, in order to accelerate our understanding of the dynamics of the global biodiversity crisis and to efficiently assess the impact of climate change. This is why the need for advanced workflows and tools to annotate, mine, query and discover new facts from the available literature is more than obvious,”
SIB is an internationally recognized non-profit organisation, dedicated to biological and biomedical data science. SIB’s data scientists are passionate about creating knowledge and solving complex questions in many fields, from biodiversity and evolution to medicine. They provide essential databases and software platforms as well as bioinformatics expertise and services to academic, clinical, and industry groups. With the recent creation of the Environmental Bioinformatics group, led by Robert Waterhouse, SIB is engaged in an unprecedented effort to streamline data across molecular biology, health and biodiversity. SIB also federates the Swiss bioinformatics community of some 900 scientists, encouraging collaboration and knowledge sharing.

Pensoft is amongst the participants of a new Horizon Europe project aiming to better evaluate the risk to wild pollinators of pesticide exposure, enhancing their health & pollination services.
Wild fauna and flora are facing variable and challenging environmental disturbances. One of the animal groups that is most impacted by these disturbances are pollinators, which face multiple threats, driven to a huge extent by the spread of anthropogenic chemicals, such as pesticides.
WildPosh (Pan-european assessment, monitoring, and mitigation of chemical stressors on the health of wild pollinators) is a multi-actor, transdisciplinary project whose overarching mission and ambition are to significantly improve the evaluation of the risk to wild pollinators of pesticide exposure, and enhance the sustainable health of pollinators and pollination services in Europe.
This aligns with the objectives of the European Green Deal and EU biodiversity strategy for 2030, emphasising the need to reduce pollution and safeguard pollinators. WildPosh focuses on understanding the routes of chemical exposure, evaluating toxicological effects, and developing preventive measures. By addressing knowledge gaps in pesticide risk assessment for wild pollinators, the project contributes to broader efforts in biodiversity conservation.
As a leader of Work Package #7: “Communication, knowledge exchange and impact”, Pensoft is dedicated to maximising the project’s impact by employing a mix of channels in order to inform stakeholders about the results from WildPosh and raise further public awareness of wild and managed bees’ health.
Pensoft is also tasked with creating and maintaining a clear and recognisable project brand, promotional materials, website, social network profiles, internal communication platform, and online libraries. Another key responsibility is the development, implementation and regular updates of the project’s communication, dissemination and exploitation plans, that WildPosh is set to follow for the next four years.
For the next four years, WildPosh will be working towards five core objectives:
1) Determine the real-world agrochemical exposure profile of wild pollinators at landscape level within and among sites
2) Characterise causal relationships between pesticides and pollinator health
3) Build open database on pollinator traits/distribution and chemicals to define exposure and toxicity scenario
4) Propose new tools for risk assessment on wild pollinators
5) Drive policy and practice.
Consortium:
The consortium consists of 17 partners coming from 10 European countries. Together, they bring extensive experience in Research and Innovation projects conducted within the Horizon programmes, as well as excellent scientific knowledge of chemistry, modelling, nutritional ecology, proteomics, environmental chemistry and nutritional biology.
Researchers have discovered two new freshwater hyphomycete (mould) species, Acrogenospora alangii and Conioscypha yunnanensis, in southwestern China.
This discovery, detailed in a study published in MycoKeys, marks the addition of these species to the Acrogenospora and Conioscypha genera, further enriching the diversity of freshwater fungi known in the region.
A research team consisting of Lu Li, Hong-Zhi Du and Ratchadawan Cheewangkoon from Chiang Mai University, Thailand, as well as Vinodhini Thiyagaraja and Rungtiwa Phookamsak from Kunming Institute of Botany, China, and Darbhe Jayarama Bhat from King Saud University, Saudi Arabia, employed comprehensive morphological analysis and multi-gene phylogenetic assessments in their study.
Notably, Acrogenospora alangii was identified on submerged branches of the medicinal plant Alangium chinense, highlighting a unique ecological association.
Freshwater fungi are highly diverse in China and frequently reported from submerged wood, freshwater insects, herbaceous substrates, sediments, leaves, foams, and living plants.
Most species are well-known as saprobes (organisms that live on decaying organisms) and they play an important role in ecological functioning as decomposers, but also can be pathogens as well as symbionts on humans and plants.
This research underscores the ecological and taxonomic richness of freshwater fungi in China, a country already recognised for its diverse fungal habitats. The findings contribute valuable insights into the roles these organisms play in freshwater ecosystems and emphasise the importance of ongoing biodiversity studies in these environments.

Zoosystematics and Evolution kicked off the year with research papers introducing 12 exciting new species from around the world. The journal, published by Pensoft on behalf of Museum für Naturkunde, is known for being at the forefront of animal research and, in particular, for sharing exciting new discoveries like those below.
Four jumping spiders from India
Four new species of Phintella were discovered in India. Generally striking in appearance, the genus now has 18 recognised species in India – second only to China.
Pleurobranchaea britannica, a newly discovered sea slug, is the first of its genus found in British waters. The unusual translucent creature also represents the second valid Pleurobranchaea species from European seas.
In the Tenasserim Mountain Range of western Thailand, researchers discovered Bungarus sagittatus, a new species of venomous elapid snake. The name sagittatus is derived from sagittata meaning arrow, referencing the dark triangular shape on its subcaudal scales which resembles a barbed arrow.
Researchers described two new species, Ariosoma gracile and Ariosoma kannani, from Indian waters, based on the materials collected from the Kochi coast, Gulf of Mannar and the West Bengal coast, along the Bay of Bengal.
Xanthomelon amurndamilumila was discovered on the North East Isles, offshore from Groote Eylandt, Australia. Its conservation status is of concern on North East Island because of habitat degradation caused by feral deer.
A new Eurasian minnow, Phoxinus radeki, was discovered in the Ergene River (Aegean Sea Basin). Salmo brunoi, a new species of trout, was discovered in the Nilüfer River, a tributary of the Susurluk River.
Ditha shivanparaensis may look like a scorpion, but looks can be deceiving. Rather, it is an arachnid, newly discovered from the tropical montane cloud forests or ‘sholas’ of the Western Ghats of India.
A team of experts has created the first database of field studies on the impacts of invasive plants on native species, communities and ecosystems in Europe.
The dataset comprises 266 peer-reviewed publications reporting 4,259 field studies on 104 invasive species across 29 European countries. It is the first harmonised database of its kind at continental scale, and is freely accessible to the scientific community for future studies. Notably, one third of the studies focused on just five species that invade several central European countries.

The comprehensive database indicates that invasive plants impact other plants, animals and microbes, all trophic levels (herbivores, parasites, plants, pollinators, predators, omnivores, decomposers and symbionts) and numerous ecosystem processes.

More than half of the studies were conducted in temperate and boreal forests and woodlands and temperate grasslands. Major knowledge gaps are found in Baltic and Balkan countries, in desert and semi-arid shrublands, subtropical forests and high mountains.
Prof. Montserrat Vilà, coordinator of this task, highlights that the database provides information on whether the invasive species increase, decrease or have a neutral effect on the ecological variable of study. This allows investigation into the circumstances in which the invader has contrasting effects.

The database will be updated as new field studies on the ecological impacts of invasive species are published. “We hope for more studies on species that are still locally rare and with restricted distribution,” Prof. Montserrat Vilà says, “this database is of interest for academic, management and policy-related purposes.”
