Researchers in Malaysia have discovered a tiny and distinctive plant that steals its nutrients from underground fungi.
Published as a new species in the open-access journal PhytoKeys, Thismia malayana belongs to a group of plants known as mycoheterotrophs. Unlike most plants, mycoheterotrophs do not perform photosynthesis. Instead, they act as a parasite, stealing carbon resources from the fungi on their roots.

The 2 cm-long plant’s unusual adaptation takes advantage of the mycorrhizal symbiosis, which is usually a mutually beneficial relationship between colonising fungi and a plant’s root system.

By stealing nutrients from fungi, it can thrive in the low-light conditions of dense forest understories where its highly specialised flowers are pollinated by fungus gnats and other small insects.
A team of botanists from the Forest Research Institute Malaysia (FRIM) collaborated with local naturalists and stakeholders to make the discovery in the tropical rainforests of Peninsular Malaysia. It was there they found the miniscule species hidden amongst leaf litter and growing near tree roots and old rotten logs.
The research team identified Thismia malayana in two locations: the lowlands of Gunung Angsi Forest Reserve in Negeri Sembilan and the hilly dipterocarp forests of Gunung Benom in the Tengku Hassanal Wildlife Reserve, Pahang.

Despite its small size, Thismia malayana is very sensitive to environmental changes and has been classified as Vulnerable according to the IUCN Red List criteria. Its limited distribution and the potential threat from trampling due to its proximity to hiking trails underscore the importance of continued conservation efforts.

Nothing like the common red, black, or brown ants, a stunning blue ant has been discovered from Yingku village in Arunachal Pradesh, northeastern India. This new species belongs to the rare genus Paraparatrechina and has been named Paraparatrechinaneela. The word “neela” signifies the color blue in most Indian languages – a fitting tribute to the ant’s unique coloration.
Entomologists Dr. Priyadarsanan Dharma Rajan and Sahanashree R, from Ashoka Trust for Research in Ecology and the Environment (ATREE) in Bengaluru, along with Aswaj Punnath from the University of Florida, collaborated to describe the remarkable new species. Their scientific description of the ant is published in the open-access journal ZooKeys.

“While exploring a tree hole about 10 feet up in a steep cattle track in the remote Yinku village one evening, something sparkled in the twilight. With the dim light available, two insects were sucked into an aspirator. To our surprise, we later found they were ants” said the researchers.
The ant was found during an expedition to Siang valley in Arunachal Pradesh to resurvey its biodiversity after the century-old ‘Abhor expedition’. The original Abor expedition from the period of colonial rule in India was a punitive military expedition against the indigenous people there in 1911-1912. A scientific team also accompanied the military expedition, to document the natural history and geography of the Siang Valley. Тhis expedition encountered several challenges, including hostile terrain, difficult weather conditions, and resistance from local tribes. Despite the challenges, it managed to explore and map large parts of the Siang Valley region, cataloguing every plant, frog, lizard, fish, bird & mammal and insects they found, with the discoveries published in several volumes from 1912 to 1922 in the Records of the Indian Museum.

Now, a century later, a team of researchers from ATREE and a documentation team from Felis Creations Bangalore have embarked on a series of expeditions under the banner “Siang Expedition”, to resurvey and document the biodiversity of the region. This expedition was funded by the National Geographic Society through the wildlife-conservation expedition grant.
“Nestled within a Himalayan biodiversity hotspot, Arunachal Pradesh’s Siang Valley presents a world of unparalleled diversity, much of it yet to be explored. However, this very richness, both cultural and ecological, faces unprecedented threats. Large-scale infrastructure projects like dams, highways, and military installations, along with climate change, are rapidly altering the valley. The impact extends beyond the valley itself, as these mountains play a critical role not only in sustaining their own diverse ecosystems but also in ensuring the well-being of millions of people living downstream”, said Priyadarsanan Dharma Rajan, corresponding author of the paper.
Paraparatrechina neela is a small ant with a total length of less than 2mm. Its body is predominantly metallic blue, except for the antennae, mandibles, and legs. The head is subtriangular with large eyes, and has a triangular mouthpart (mandible) featuring five teeth. This species has a distinct metallic blue colour that is different from any other species in its genus.

Blue is relatively rare in the animal kingdom. Various groups of vertebrates, including fish, frogs, and birds, as well as invertebrates such as spiders and flies and wasps, showcase blue coloration. In insects, it is often produced by the arrangement of biological photonic nanostructures, which create structural colours rather than being caused by pigments. While blue coloration is commonly observed in some insects like butterflies, beetles, bees, and wasps, it is relatively rare in ants. Out of the 16,724 known species and subspecies of ants worldwide, only a few exhibit blue coloration or iridescence.
The discovery of Paraparatrechina neela contributes to the richness of ant diversity and represents the unique biodiversity of the Eastern Himalayas, and its blue coloration raises intriguing questions. Does it help in communication, camouflage, or other ecological interactions? Delving into the evolution of this conspicuous coloration and its connections to elevation and the biology of Paraparatrechina neela presents an exciting avenue for research.

One of the main problems of the world’s oceans, reported by many scientific studies, is microplastic pollution. It is also one of the main sources of pollution in the Black Sea. Our new study in BioRiskdetails microplastic contamination in five fish species important for commercial fishing (Garfish, Мullet, Knout goby, Pontic shad, and Mediterranean horse mackerel). The fish were collected from the Sozopol area of the Bulgarian Black Sea coast.

Our results show a wide variety of micropollutants originating from commonly used items such as plastic cups, stirrers, bags, soft drink bottles, fishing nets, packaging, аnd personal hygiene products. These objects systematically enter the Black Sea and degrade into microplastic particles. Microplastics (MPs) were found in all studied tissues of the fish in the form of pellets, fibers and fragments. Pellets were found most frequently, followed by irregularly shaped fragments, while fibers were the least numerous.
Stereomicroscope picture of morphological types of microplastics (arrowheads) recognized in the studied specied from: A) Garfish; B) Mullet C) Pontic shad and D) Mediterranean horse mackerel.
The bulk of the isolated plastics are made of polyethylene (PE) and polyethylene terephthalate (PET). PE is found in plastic bottles, cups, stirrers, and plastic bags. This polymer is very light and floats on the surface of the sea because its density is lower than that of water. PET, on the other hand, is denser than water and more likely to sink and accumulate in it and in organisms living on the seafloor. These polymers are widely used in fabrics, nets, ropes, and strings used for fishing, one of the main economic activities in the Black Sea. The predominant polymer type, PE, corresponds to the content of manufactured plastics all around Europe, as almost half of the plastics produced in Europe are reported as PE.
The sinking and sedimentation of plastics relate to the fact that the upper layer of the Black Sea is less dense than that of other seas. Furthermore, the weight of these particles increases due to the accumulation of marine plants and nutrients on them, and this can affect the distribution of plastics and their sedimentation on the seabed.

Judging by the obtained results and the amount and type of polymers found in the study and the literature, the source of contamination, in our opinion, can be mainly attributed to domestic wastewater discharges coming from the washing of synthetic fabrics. In Bulgaria, wastewater is discharged – directly or after purification – into marine and freshwater ecosystems, as is the case in other neighbouring countries along the Black Sea coast. However, detailed studies are needed to prove this hypothesis.
Considering the wide variety of MP types detected in the digestive tracts of the fish, we assume that they regularly ingested MPs during feeding. Many nutrients are also held on the plastic particles, which deceives the fish into perceiving them as food.

It has been reported that plastics smaller than 1000 μm can reach the digestive tract or the gills of fish, and in turn can cause adverse effects such as a weak immune response or reduced fertility.
MPs can also accumulate in predatory fish species. Unfortunately, very limited research was performed on bioaccumulation and biomagnification in food webs, therefore more studies are needed to reach this conclusion.
MPs enter seawater food chains in different pathways and threaten entire ecosystems through their ability to transport pollutants, pathogenic microorganisms, and alien species. Bearing in mind the intensifying economic activity on the Black Sea coast and the consequent influence on the riverine water quality, river mouths can be considered potential sources of MPs. Particularly concerning is the area near the Kamchia River mouth, which is the biggest intra-territorial river in Bulgaria, entering directly into the Black Sea, with a catchment area of more than 5 300 km2 . This catchment and the entire Black Sea coast, where agriculture is well developed is a potential source of MPs, which have the ability to absorb and release toxic chemicals of organic and inorganic origin such as bisphenol A, PCBs and DDT, creating an additional potential risk to human health.

Humans are exposed to BPA in the environment they live in, from the air we breathe to the food and drinks we consume. So, even if BPA intake is below accepted limits, this does not guarantee that the additive will not accumulate and cause more pronounced effects and chronic toxicity in the food chain, given its tendency to accumulate.
It is important that future research determines the toxicological side effects of plastic ingestion for fish communities in both benthic and pelagic habitats. However, even if we stop introducing plastics into the water system, both groups of fish will continue to be impacted, since the number of microplastics can increase due to the breakdown of larger plastics in the environment.
This study shows the need to carry out further studies of microplastics using different types of microscopic and spectral analysis. Even though microplastics may not pose a risk to humans who consume fish, these contaminants pose a potential risk to marine food webs and endangered species. We found particles of different sizes, types and colours in different fish species, and believe the variability of polymer types in fish can indicate the polymer types in water to some extent. Our results show that fish are important as ecological bioindicators and serve as a basis for future studies on microplastic pollution in tourist sandy beaches.

Researchers have discovered a new distinctive and secretive snake species in the Hejaz region of Saudi Arabia.
Rhynchocalamus hejazicus is a small snake bearing a black collar and reddish colouration. A completely black variation of of the species known as a ‘melanistic morphotype’ was also discovered.
Melanistic morphotype of Rhynchocalamus hejazicus.
The snake’s genus Rhynchocalamus previously had a large distribution gap, stretching between the Levant and coastal regions of Yemen and Oman. However, the new species is widely distributed between these areas, prompting the research team to dub it “the missing piece of the puzzle.”

Rhynchocalamus hejazicus inhabits sandy and stony soils with varying vegetation cover and is found in habitats disturbed by humans, suggesting the species should not be categorised as threatened according to IUCN criteria.
Habitats of the holotype and two paratype specimens of R.hejazicus.
The species’ natural history and behaviour remain unclear, and further monitoring and conservation efforts are necessary to better understand its ecological dynamics. However, it appears that Rhynchocalamus hejazicus is predominantly nocturnal as all encountered individuals were active at night.
“The discovery of a new species of snake widespread in the central-western regions of Saudi Arabia is surprising and gives rise to the hope that more undiscovered species might be present in the Kingdom,” the authors say.

Most observations of the new species are the result of intense sampling efforts in a vast area around the ancient Arabic oasis city of AlUla, fostered by the Royal Commission for AlUla, Saudi Arabia, which is pushing forward scientific activities and explorations to promote conservation in the region. Recent research in Saudi Arabia has led to fruitful collaborations and findings like this study, to which many experts from multiple teams contributed significantly.
The discovery of such a distinctive snake highlights the existing gap in knowledge of rare and secretive species, and the need to enhance sampling efforts and monitoring strategies to fully capture species diversity in unexplored areas.

Late May 2024 saw the whole content ever published in VCS added to the Core Collection of the renowned academic platform, further boosting its discoverability, accessibility and reliability to researchers and other stakeholders alike, confirms the Indexing team of Pensoft and the ARPHA scholarly publishing platform.
“Many thanks to IAVS as owner and Pensoft as publisher, who made this success story possible. However, most of all, this early inclusion into the Web of Science Core Edition is due to the good articles of our authors and the great volunteer service our Associate Editors, Guest Editors, Linguistic Editors, Editorial Review Board members, and other reviewers did and do for VCS,”
the Chief Editors comment on the latest success.
The news means that VCS is soon to receive its very first Journal Impact Factor (JIF): allegedly the most popular and sought after journal-level metric, which annually releases the citation (or “impact”) rate of a given scholarly journal over the last period. By the end of next month, for example, we will know how different journals indexed by WoS have performed compared to each other, based on the number of citations received in 2023 (from other journals indexed by WoS) for papers published in 2021 and 2022 combined.
In 2022, VCS and its all-time publications were also featured by the largest and similarly acclaimed scientific database: Scopus, thus receiving its very first Scopus CiteScore* last June. At 2.0, the result instantly gave a promise of the widely appreciated content published in the journal.
In an editorial, published in the beginning of 2024, the Chief Editors assessed the performance of the journal and analysed the available data from Scopus to predict the citation rates for the journal in the next few years. There, the team also compared the journal’s latest performance with similar journals, including the other two journals owned by the IAVS (i.e. Applied Vegetation Science and Journal of Vegetation Science). Given that as of May 2024 the Scopus CiteScoreTracker for VCS reads 2.5, their optimistic forecasts seem rather realistic.
“The VCS articles of 2023 were on average even better cited than those in Applied Vegetation Science of the same year and had reached about the same level as Journal of Vegetation Science and Biodiversity and Conservation,”
they concluded.
In a recent post, published on the IAVS blog, on behalf of the four VCS Chief Editors, Prof. Dr. Jürgen Dengler further comments on the latest achievements of the journal, while also highlighting particularly valued recent publications.
The team also uses the occasion to invite experts in the field of vegetation science to submit their manuscripts in 2024 to make use of the generous financial support by the IAVS. Given the increasing interest in VCS, the journal also invites additional linguistic editors, as well as reviewers who wish to join the Editorial Review Board.

About Vegetation Classification and Survey:
Vegetation Classification and Survey (VCS) is an international, peer-reviewed, online journal on plant community ecology published on behalf of the International Association for Vegetation Science (IAVS). It is devoted to vegetation survey and classification at any organisational and spatial scale and without restriction to certain methodological approaches.
The scope of VCS is focused on vegetation typologies and vegetation classification systems, their methodological foundation, their development and their application. The journal publishes original papers that develop new typologies as well as applied studies that use such typologies, for example, in vegetation mapping, ecosystem modelling, nature conservation, land use management, or monitoring. Particularly encouraged are methodological studies that design and compare tools for vegetation classification and mapping, such as algorithms, databases and nomenclatural principles, or are dealing with the conceptual and theoretical bases of vegetation survey and classification.
VCS also includes two permanent collections (or sections): “Ecoinformatics” and “Phytosociological Nomenclature”.

Ecosystem services’ (ES) integration into global policies is widely recognized as a hope for environmental sustainability, as they provide a robust framework for representing natural values. The role of healthy ecosystems in combating climate change-related risks and ensuring the sustainability of ecosystem services that are critical for human-natural life is well understood, and in this context, the protection and sustainability of Integrated ES areas, which represent the highest ecological functional areas in this sense, need to be highlighted. Integrated ES can be a potent tool to inform and guide spatial decision-making. However, presently, there is a need to improve the content of related conventional tools on how to introduce and involve their roles in decision-making processes.
A map of Istanbul showing the integrated ecosystem services potential of the current situation.
Our paper, published in the journal One Ecosystem, investigates the incorporation of this problem, underlines ES significance as the Integrated ES, and transfers this information into spatial decision-making. The content of the paper discusses the potential contributions and limitations of the integration. It provides solid suggestions on how Integrated ES can be operationalized in Istanbul’s high-level plans.

Within theBiodiversity Community Integrated Knowledge Library (BiCIKL) project, 14 European institutions from ten countries, spent the last three years elaborating on services and high-tech digital tools, in order to improve the findability, accessibility, interoperability and reusability (FAIR-ness) of various types of data about the world’s biodiversity. These types of data include peer-reviewed scientific literature, occurrence records, natural history collections, DNA data and more.
By ensuring all those data are readily available and efficiently interlinked to each other, the project consortium’s intention is to provide better tools to the scientific community, so that it can more rapidly and effectively study, assess, monitor and preserve Earth’s biological diversity in line with the objectives of the likes of the EU Biodiversity Strategy for 2030 and the European Green Deal. Their targets require openly available, precise and harmonised data to underpin the design of effective measures for restoration and conservation, reminds the BiCIKL consortium.
Since 2021, the project partners at BiCIKL have been working together to elaborate existing workflows and links, as well as create brand new ones, so that their data resources, platforms and tools can seamlessly communicate with each other, thereby taking the burden off the shoulders of scientists and letting them focus on their actual mission: paving the way to healthy and sustainable ecosystems across Europe and beyond.
Now that the three-year project is officially over, the wider scientific community is yet to reap the fruits of the consortium’s efforts. In fact, the end of the BiCIKL project marks the actual beginning of a European- and global-wide revolution in the way biodiversity scientists access, use and produce data. It is time for the research community, as well as all actors involved in the study of biodiversity and the implementation of regulations necessary to protect and preserve it, to embrace the lessons learned, adopt the good practices identified and build on the knowledge in existence.
This is why amongst the BiCIKL’s major final research outputs, there are two Policy Briefs meant to summarise and highlight important recommendations addressed to key policy makers, research institutions and funders of research. After all, it is the regulatory bodies that are best equipped to share and implement best practices and guidelines.
Most recently, the BiCIKL consortium published two particularly important policy briefs, both addressed to the likes of the European Commission’s Directorate-General for Environment; the European Environment Agency; the Joint Research Centre; as well as science and policy interface platforms, such as the EU Biodiversity Platform; and also organisations and programmes, e.g. Biodiversa+ and EuropaBON, which are engaged in biodiversity monitoring, protection and restoration. The policy briefs are also to be of particular use to national research funds in the European Union.
One of the newly published policy briefs, titled “Uniting FAIR data through interlinked, machine-actionable infrastructures”, highlights the potential benefits derived from enhanced connectivity and interoperability among various types of biodiversity data. The publication includes a list of recommendations addressed to policy-makers, as well as nine key action points. Understandably, amongst the main themes are those of wider international cooperation; inclusivity and collaboration at scale; standardisation and bringing science and policy closer to industry. Another major outcome of the BiCIKL project: the Biodiversity Knowledge Hub portal is noted as central to many of these objectives and tasks in its role of a knowledge broker that will continue to be maintained and updated with additional FAIR data-compliant services as a living legacy of the collaborative efforts at BiCIKL.
The second policy brief, titled “Liberate the power of biodiversity literature as FAIR digital objects”, shares key actions that can liberate data published in non-machine actionable formats and non-interoperable platforms, so that those data can also be efficiently accessed and used; as well as ways to publish future data according to the best FAIR and linked data practices. The recommendations highlighted in the policy brief intend to support decision-making in Europe; expedite research by making biodiversity data immediately and globally accessible; provide curated data ready to use by AI applications; and bridge gaps in the life cycle of research data through digital-born data. Several new and innovative workflows, linkages and integrative mechanisms and services developed within BiCIKL are mentioned as key advancements created to access and disseminate data available from scientific literature.
While all policy briefs and factsheets – both primarily targeted at non-expert decision-makers who play a central role in biodiversity research and conservation efforts – are openly and freely available on the project’s website, the most important contributions were published as permanent scientific records in a BiCIKL-branded dedicated collection in the peer-reviewed open-science journal Research Ideas and Outcomes (RIO). There, the policy briefs are provided as both a ready-to-print document (available as supplementary material) and an extensive academic publication.
Currently, the collection: “Towards interlinked FAIR biodiversity knowledge: The BiCIKL perspective” in the RIO journal contains 60 publications, including policy briefs, project reports, methods papers, conference abstracts, demonstrating and highlighting key milestones and project outcomes from along the BiCIKL’s journey in the last three years. The collection also features over 15 scientific publications authored by people not necessarily involved in BiCIKL, but whose research uses linked open data and tools created in BiCIKL. Their publications were published in a dedicated article collection in the Biodiversity Data Journal.
The proposed model of an entomological block is ready for printing on a standard 3D printer. In addition to the usual positioning of glue boards and labels along the Z-axis, the model also offers targeting devices that enable precise positioning of the entomological pin along the X- and Y-axes.
Dimensions of the entomological pinning block with metal rail.
The model is offered in two variants – one for immediate use after printing and another that requires the fabrication of an additional steel rail measuring 100 × 30 × 5 mm, against which the tip of the pin rests during positioning along the Z-axis. The rail is also used to increase the overall mass of the fixture. The overall dimensions of the device are 100 mm in length, 35 mm in width and 37 mm in height.
The proposed entomological block is intended for widespread use by entomologists, particularly those using insect glue boards. It is applicable to large entomological collections with individual specimen numbering and its use can ensure that entomological pins are positioned on the label so as not to disrupt the integrity of the number or barcode. It can also be modified to suit the needs of the user and can be sliced and printed directly on a 3D printer.

As climate change continues its relentless march, the world faces not only rising temperatures and extreme weather, but also an insidious threat to our homes: invasive termites. And the bill could be steep – invasive termites currently cost over 40 billion USD annually.
In a new study published in the open-access journal Neobiota, PhD student Edouard Duquesne and Professor Denis Fournier from the Evolutionary Biology & Ecology lab (Université libre de Bruxelles) unveil the unsettling reality of invasive termites’ potential expansion into new territories.
Their research reveals that as temperatures rise and climate patterns shift, cities worldwide, from tropical hotspots like Miami, Sao Paulo, Lagos, Jakarta or Darwin to temperate metropolises like Paris, Brussels, London, New York or Tokyo, could soon find themselves under siege by these tiny yet destructive pests.
But how do termites, typically associated with tropical climates, find their way into cities far beyond their natural habitat? The answer lies in the interconnectedness of our modern world. Urbanisation, with its dense populations and bustling trade networks, provides the perfect breeding ground for termite invasions.
Moreover, the global movement of goods, including wooden furniture transported by private vessels, offers unsuspecting pathways for these silent invaders to hitch a ride into our homes.
“A solitary termite colony, nestled within a small piece of wood, could clandestinely voyage from the West Indies to your Cannes apartment. It might lurk within furniture aboard a yacht moored at the Cannes Film Festival marina.”
“Mating is coming. Termite queens and kings, attracted by lights, may initiate reproduction, laying the groundwork for new colonies to conquer dry land.”
Researchers Edouard Duquesne and Denis Fournier.
Duquesne and Fournier’s research emphasises the need for a paradigm shift in how we approach invasive species modelling. By integrating connectivity variables like trade, transport, and population density, their study highlights the importance of understanding the intricate interactions that facilitate termite spread.
In light of these findings, the researchers urge swift action from policymakers and citizens alike. Major cities, regardless of their climate zone, must implement strict termite control measures to protect homes and infrastructure.
“Citizens can play a crucial role by leveraging technology, such as AI-assisted apps like iNaturalist, to detect and report potential termite sightings, turning ordinary residents into vigilant guardians of their environment,” say the researchers.
“As we confront the challenges of a rapidly changing climate, awareness and proactive measures are our best defence against the creeping menace of invasive termites,” they conclude.

Research from Wageningen University and Research, the Netherlands, reveals invasive lionfish are rapidly expanding their territory in the Mediterranean sea, causing severe ecological damage.
Published in the open-access journal NeoBiota, the study shows the lionfish species Pterois miles – known as the devil firefish – has established presence in the eastern Mediterranean, with observations now extending to colder waters previously thought to be unsuitable for the species.

Originating from the Indo-Pacific region, the lionfish species Pterois miles and Pterois volitans are regarded as the most successful and lethal invasive fishes in marine ecosystems, with the capacity to drastically affect local fish communities and biodiversity in invaded areas.
The invasion of Pterois miles in the Mediterranean Sea began around ten years ago. Genetic studies reveal the invasive fish originated from the Red Sea and likely entered through the Suez Canal.

Lionfish are generalist predators and impact ecosystems by preying extensively on local fishes, including endemics of high conservation value. As they are unaccustomed to lionfish, native prey species usually do not flee from this new predator.
“After years studying these predators, I find it amazing how they can easily adjust to so many different environments and be successful in areas so different from where they evolve.”
“It is always impressive to see how such a flamboyant and–to us–conspicuous predator can approach its prey without being noticed”
The study’s lead author, Davide Bottacini.
The fin spines of Pterois miles are highly venomous. A sting can cause extreme pain, sickness, convulsions, minor paralysis, and breathing difficulties in humans. Immediate emergency medical attention is recommended for anyone stung by the species.
By reviewing existing scientific data, researchers identified gaps in current understanding of the lionfish’s interactions with Mediterranean ecosystems.
They suggest that, while they consider the eradication of invasive lionfish impossible, tackling questions such as the community-level impact of them in the Mediterranean, and the evolutionary and learned responses in prey, will add to the body of knowledge on the best documented invasion in marine ecosystems.

Such information provides insights vital for biodiversity conservation, with practical implications for policy makers aiming to devise efficient mitigation plans.
Citizen science initiatives for tracking and reporting lionfish sightings are encouraged to provide valuable data that supports ongoing research efforts. Such community involvement is essential for enhancing understanding of the invasion dynamics and devising effective control measures.
