Biodiversity restated: > 99.9% of global species in Soil Biota

Soil’s vast biodiversity is under severe threat from topsoil erosion and poisoning, potentially leading to widespread extinctions.

More than 99.9% of global species diversity is found within soils, according to a new review paper published in ZooKeys.

Comparing different studies on soil biota, author Robert J. Blakemore challenges previous estimates, which suggested a much lower proportion of life in soils. “Most life is found in Soil and most is microbial, affected by the current mass extinction event having profound effects influencing all evolution on Earth,” he says.

From the review paper: “Micro monde” progressions with microbial proportions greatly increased from Blakemore after Larsen et al.

“Soil filters and stores freshwater stocks (being subject to Earth tides!) and, as well as ~ 99% of human food, it provides most building materials plus many of our essential medicines/antibiotics. Thus, an important metric must be the scope and snapshot status of living or dormant Soil biota.”

One of the most recent estimates suggests that the soil realm is home to approximately 2.1 x 10²⁴ taxa, which is thought to be more than 99.9% of global species biodiversity, mainly comprised of bacteria and other microbes.

The more you look, the more you find (lhs, pin-head after SCIENCE 2002; rhs, Bacteria on a pin tip courtesy Dr Kateryna Kon of Kharkiv National Medical University).

“Soil also supplies >99.7% of calorific food (just 0.3% from ocean plus 0.3% from aquaculture mostly fed with farmed stockfeed); with just about 6% total global protein from all fish; soil filters and stores most freshwater and is thus responsible for hydrological-recycle rainfall on land,” Blakemore says.

“My other paper last year on Biomass shows Soil houses >99% of organic carbon and it is the loss of this vital resources that is the greatest contributor to atmospheric carbon increase, despite the ‘greening’ effect on land.”

Blakemore, R. J. (2024). Biomass Refined: 99% of Organic Carbon in Soils. Biomass, 4(4), 1257-1300. https://doi.org/10.3390/biomass4040070.

However, this immense biodiversity is under threat. “Soil erosion is one of our greatest global issues of concern, and one of the most ignored. Droughts, floods, deserts, poisoning, capping and so on are affecting all soils and, due to this massive soil loss, plants are incapable of thriving. At the same time deforestation continues, mainly clearing for cattle pastures or soy fields to feed CAFO cows (or other stock),” the author says.

The loss of soil biodiversity has far-reaching consequences, leading to ecosystem degradation, reduced food production, and loss of potentially valuable resources, such as sources of medicines and antibiotics. Furthermore, soil loss inevitably results in silent species loss, mostly of microbes that are most dominant in soils, but also of more obvious soil macrobes, and specifically of earthworms, which are vital for soil health.

Around 7,000 ‘true’ earthworm species have been described, but estimates suggest the total number of earthworm species may be closer to 30,000-35,000 globally. “Due to their high endemicity and Soil’s heterogeneity, their unknowns are legion,” the author notes in his paper.

From the review paper: Global Soil Biodiversity Atlas (GBIF 2016) reporting ~ 667,000 soil biota or just about one third of known 2 million). Note that earthworms have 7,000 known and > 30,000 estimated species. Bacteria had 15,000 known species but estimated over one million (< 1.5% described). However, when microbes (excluding viruses) are properly considered and counted, as herein, soil unknowns are much higher (likely just < 0.0001% known at best). Vascular plants add ~ 400,000 species (cf. Anthony et al. 2023 with 466,000 angiosperm “Plantae”).

Earthworms enhance microbial activity, improve soil structure, and promote plant growth, which is why Blakemore suggests that “a simple solution to soil degradation is to attempt, in any way and at all times, to preserve and enhance earthworm populations.”

“Healthy soils are carbon-rich, hugely biodiverse and are a massive sponge for water – neither flooding nor drying during climatic extremes,” the author says, a reminder that healthy soils are not only vital for maintaining biodiversity, but also indispensable in supporting essential functions of planet and human survival.

“Due to the most pressing problem of topsoil erosion and irreversible extinction losses, a major shift should be realizing the overwhelming importance and fragility of our precious Soil,” Robert Blakemore writes in his paper.

Calling for a change in attitudes and funding to recognise the true scope of soil biodiversity, he encourages the formation of a dedicated Soil Ecology Institute that would catalogue, research and reverse the mass degradation of our planet’s most crucial, yet most neglected ecosystem – that of the Soil Realm.

Airport dogs can prevent invasive pests from entering new territories

Biosecurity inspectors and detector dogs are an effective combination in combatting the spread of invasive species.

Researchers at the University of Melbourne’s Centre of Excellence for Biosecurity Risk Analysis (CEBRA) have highlighted biosecurity risks posed by air passengers and emphasised the value of border interventions such as detector dogs in mitigating these threats.

Published in the open-access journal NeoBiota, the study focused on domestic air travel into Tasmania, Australia, an island state with an especially low pest presence due to its geographic isolation.

Airport sign reading 'biosecurity Tasmania'

Researchers utilised an extensive database of more than 66,000 biosecurity risk interceptions from over 6 million passengers entering Tasmania from mainland Australia. With this, they applied advanced statistical modelling tools to assess how effective different interventions are at catching risky material at the border.

Their analysis found that air passengers pose a significant biosecurity risk, with pests potentially introduced via items like fruits, vegetables, and animal products carried in luggage.

To combat this risk, border interventions using biosecurity inspectors and detector dogs were found to be effective, both by encouraging voluntary declarations by passengers and detecting risk items that passengers failed to declare.

While biosecurity inspectors play a significant role, detector dogs are especially effective, detecting a higher rate of risky items and targeting undeclared materials that might otherwise go unnoticed. The presence of detector dogs substantially increased interception rates, including for items linked to the spread of the invasive fruit fly.

Airport sign reading 'Help protect out beautiful island - biosecurity acheckpoint'

Lead author Dr Nicholas Moran said: “Dogs being great at sniffing things out might seem obvious, but measuring precisely how effective different interventions are, what they capture, and how, is incredibly valuable information for biosecurity operations.

“Fruit flies are a serious risk to Tasmania, and many parts of the world. So, this work is about knowing what biosecurity interventions to deploy, and where is best to deploy them to reduce the risk of outbreaks.”

The study is a part of the “Risk Analysis of Tasmanian Border Inspection Approaches and Procedures” project, conducted by CEBRA with Biosecurity Tasmania. The two-phase project investigated the invasive risk of five pest species that are common across Australia’s mainland but are not currently found in Tasmania.

Pensoft joins new Horizon Europe project to help tackle terrestrial invasive alien species

Pensoft will play a vital role in public awareness, engagement and promoting effective strategies for monitoring and managing IAS.

*The Chinese muntjac* *(Muntiacus reevesi)* *is an invasive alien species for Europe with established populations across the western part of the continent*. *Photo by Mario Shimbov (Pensoft).*

As one of the partners in charge of maximising the project’s impact, Pensoft will work on OneSTOP’s visual branding, communication, dissemination and exploitation, and the development of a data management plan for the project.

Invasive alien species (IAS) pose one of the most significant threats to global biodiversity, contributing to species extinctions, ecosystem degradation, and economic losses exceeding $400 billion annually.

To tackle this, the EU enforces Regulation (EU) 1143/2014 and the Biodiversity Strategy for 2030, aiming to prevent IAS introduction, enhance early detection, and manage their spread. Member States coordinate efforts with scientific support and citizen engagement to minimise their impact and protect Europe’s biodiversity. Addressing this urgent challenge, the EU Horizon project OneSTOP has officially launched as part of a coordinated European effort to combat biological invasions in terrestrial environments.

Comprehensive Approach to Tackling Invasive Alien Species

OneSTOP is one of two ambitious projects funded under the Horizon Europe programme, the other being GuardIAS, which focuses on marine and freshwater habitats. The two collaborative initiatives held their joint official kick-off meeting in January at the Joint Research Centre in Ispra, Italy. Together, these projects aim to develop innovative solutions for detecting, preventing, and managing invasive alien species across all ecosystem realms.

Coordinated by Dr Quentin Groom from Meise Botanic Garden, Belgium, and Prof Helen Roy from the UK Centre for Ecology and Hydrology, OneSTOP will integrate advanced scientific research, cutting-edge detection technologies, and policy-driven strategies to enhance biosecurity across Europe.

*The ОneSTOP project consortium at the project’s kick-off meeting held on 20-24 January 2025 in Ispra, Italy.*

The project is structured around four key objectives:

Improve species detection and response time by incorporating computer vision, environmental DNA (eDNA) analysis and citizen science initiatives.
Facilitate swift action against invasive species threats by openly sharing data in international standards for biodiversity data with stakeholders who need it.
Support policy-makers in making informed decisions about where and how to allocate resources for invasive species management by developing data-driven systems.
Ensure stakeholder collaboration and knowledge exchange by implementing Living Labs at the regional level and an international policy forum, thereby encouraging socio-political action.

OneSTOP aligns with the European Alien Species Information Network (EASIN) mission to protect EU biodiversity by improving IAS management through advanced biosecurity technologies and enhanced data integration. By fostering collaboration with the Joint Research Centre (JRC) and supporting Member States with innovative tools, the project strengthens the EU’s capacity to detect, respond to, and mitigate IAS threats in line with existing regulations.

Pensoft’s role in OneSTOP

As the leader of Work Package 1, Pensoft is responsible for shaping OneSTOP’s visual identity and developing a comprehensive strategy for communication, dissemination, and impact. This includes crafting a data and knowledge management plan to ensure the project’s findings are effectively shared and utilised. By fostering collaboration with key biosecurity networks, these efforts will strengthen OneSTOP’s long-term influence.

A key part of this work is to raise awareness about invasive alien species (IAS) and their pathways, ensuring that policymakers, researchers, and the public understand their impact and the importance of prevention. Pensoft will contribute to translating complex scientific findings into accessible content—including infographics, policy briefs, and interactive visualisations—to engage policymakers, researchers, and the public. These efforts will ensure that IAS knowledge is effectively shared, fostering collaboration and informed decision-making across sectors. Knowledge transfer materials will be shared through various channels, including OneSTOP’s five Living Labs across Europe, where stakeholders will be actively engaged in outreach and citizen science initiatives.

Pensoft will play a vital role in strengthening public awareness, fostering engagement, and promoting effective strategies for monitoring and managing IAS.

The Ghibli fish: new ‘painted’ species named after Princess Mononoke

The deepwater tilefish was first spotted by researchers on an online seafood market.

Picture in your mind the discovery of a new species.

What do you see? Researchers cutting through dense, untouched rainforests? Perhaps a submarine plunging into a deep-sea trench, illuminating a new world?

Well, it’s not always quite so dramatic. In fact, researchers in China discovered Branchiostegus sanae when they were scrolling through online seafood markets and noticed some deepwater tilefish with unique cheek patterns.

These red-and-white facial markings reminded the research team of the Studio Ghibli character San from Princess Mononoke, whom they chose to honour in their naming of the species.

Published in the open-access journal ZooKeys, Branchiostegus sanae is a deepwater tilefish belonging to the family Branchiostegidae. Researchers confirmed its new-species status using genetic analysis, and chose “sanae” as the specific epithet (that’s the part that differentiates species within a genus), in a nod to Hayao Miyazaki’s animated creation.

“Finding a new species in this group is a rare and fortunate event, especially one as distinctive as Branchiostegus sanae.

“In Princess Mononoke, San is a young woman raised by wolves after being abandoned by her human parents. She sees herself as a part of the forest and fights to protect it. The film delves into the complex relationship between humans and nature, promoting a message of harmonious coexistence between the two: something we hope to echo through this naming.”
Lead author, Haochen Huang.

The Chinese fishermen who sell the new-to-science species call it the“鬼马头鱼” (ghost horsehead fish), and this also contributed to the species name because, fittingly, “Mononoke” (もののけ) refers to supernatural spirits in Japanese folklore.

As their name suggests, deepwater tilefish are found at great depths, with some species found 600 m below the surface. They are important food fish, commonly found in seafood markets in East and Southeast Asia.

Branchiostegus sanae is far from the only new species discovered at a seafood market. Indeed, a new giant isopod was recently dicovered in the same way – and also recieved a pop-culture inspired name. Check it out below!

So far only 31 species are described in the family Branchiostegidae, and 19 species in the genus Branchiostegus. From 1990 to 2024, only three new species of Branchiostegus have been described.

The study, led by researchers from the South China Sea Institute of Oceanology, Chinese Academy of Science, Zhejiang University and Ocean University of China, involved a combination of morphological analysis and genetic sequencing. Specimens were deposited in prestigious marine biological collections in China to facilitate future research.

Take vegetation succession into account when planning solar parks, otherwise problems can grow up

The planning and sustainable management of ground-mounted solar parks can be enhanced by the consideration of vegetation succession.

Large-scale ground-mounted solar parks are relatively new phenomena. Over time, ideas have been put forward about how they can accommodate biodiversity, and some parks are indeed becoming more multifunctional, for example by providing habitats for plants, invertebrates and birds. From a background of studying idyllic ecosystems in dynamic change, Dr. Markus Zaplata, research technician at Anhalt University of Applied Sciences, Germany, has come to appreciate the biology of solar parks, and has found evidence that they can support a wide range of biodiversity.

His research, published in the open-access journal One Ecosystem, proves the previously overlooked fact that vegetation succession also takes place in solar parks, and that certain intrinsic technical structures can even help self-seeded woody plants live there. Vegetation succession refers to the directional development from easily spreading but low-competitive species such as herbs and grasses towards highly competitive species such as woody plants. Mowing alone is not enough to deal with woody plants, he argues. “The fact is that subsurface woody structures continue to grow after mowing, and may at some point massively interfere with the solar installations”, he says.

With 18 years of experience in studying vegetation succession, Dr. Zaplata has supported a research project on biodiversity in solar parks since 2021.

“I do the mowing myself, so I experience the very things I write about in this paper”, he says.

Mowing can also be expensive and labour-intensive, he adds, suggesting that other construction methods and grazing could provide a more sustainable alternative.

Including insights from succession research can make global solar energy landscapes more sustainable, he argues. “The universal and unstoppable ecological process of succession is here linked to a management recommendation that can bring society closer again, on the new or neutral territory of new energy landscapes. In fact, new and old professions are connected, for example solar park manager and livestock farmer.”

“Finally, and very importantly, my article points out that experts with in-depth predictive knowledge of dynamic vegetation processes must be consulted in the future on everything that has to do with the technical transformation of landscape units, including solar parks,” he says in conclusion.

The human dimensions of biological invasions – involving stakeholders in addressing invasive species

Can the knowledge and experience of recreational anglers in Iceland help us understand how far the invasive flounder has spread in the country?

Guest blog post by Theresa Henke

For centuries, all kinds of species have been transported by humans around the globe, allowing them to cross the boundaries of their native range and settle in new ecosystems. Over the past decades the numbers of these introduced species and the impacts they cause have been continuously increasing. Biological invasions nowadays represent one of the biggest threats to biodiversity worldwide.

Humans are and have always been an essential part of biological invasions and in order to fully understand the issue and how to tackle it, we need to understand and include the human dimensions in our research.

My research on European flounder in Iceland began in 2017 when I was writing my Master’s thesis. The flounder is a flatfish species that had been officially documented in the country since 1999 but not much was known on its impacts. In my thesis I looked at the flounder through ecological lenses, trying to identify how the presence of the flounder affects other species. Living in a small community in the Westfjords of Iceland during this time, I got to meet many local people who shared their personal stories, experiences and knowledge with me in every-day conversations. I truly enjoyed these conversations and learning about the species I study from different perspectives beyond the academic settings. These exchanges sparked my interest in exploring the human dimensions of biological invasions and, looking back, have really shaped my academic path going forward.

In our recently published NeoBiota study “Have you seen this fish? – Important contribution of stakeholder observations in documenting the distribution and spread of an alien fish species in Iceland” we wanted to explore how the knowledge and experience of recreational anglers in Iceland can help us understand how far the flounder has spread in Iceland. The flounder in Iceland had only received little scientific interest before and the available information was limited and scattered between different institutions and scientists. Recreational anglers, on the other hand, who chase after native salmon, trout, and char in the Icelandic rivers and lakes, often encounter the flounder.

In 2019, we asked anglers in Iceland to take part in an online survey, where we asked them different questions about the flounder, including where in Iceland they have seen or caught it. We then compared locations named by anglers to the locations that were available from different databases of the Marine and Freshwater Research Institute of Iceland. The locations we received included data collected during scientific surveys and research projects done by the institute as well as observations that were reported to the institute by the public (mostly recreational anglers and commercial fishermen).

Our goal was to evaluate whether observations made by stakeholders, in this case the recreational angling community in Iceland, could be a good source of additional information for monitoring of an alien fish species. Collecting information on the distribution and spread of an alien species is a very important step in addressing biological invasions but is often underdeveloped because not enough resources (i.e. money, time, scientists…) are made available.

We have shown that neither source offers a perfect solution to the monitoring of the flounder in Iceland. But we show that each of the sources has their own advantages and disadvantages and by combining them, we are able to get a much clearer picture of where in Iceland the flounder currently occurs and how fast it spread in the early years. Information that was shared by stakeholders, whether it was in our study or to the databases of the Marine and Freshwater Research Institute, played a big role in better understanding the flounder in Iceland.

The interactions with the recreational angling community in Iceland during my PhD have taught me a lot about the flounder in Iceland but even more about my own approach to science. I think as scientists, we should more often take a step outside of our academic bubble and take a look at the issue we are studying from the perspectives of the public and other stakeholders. In the case of biological invasions, we can learn a lot from those who are directly confronted by an invasive species, regardless of whether they have a scientific degree or not.

Anti-melanoma activity found in green-produced nanosilver-chlorhexidine complex

A trustful concentration range was established in which the active agent was effective against the cancer cells but remained non-toxic to the normal cells.

Melanoma is a fast-progressing skin cancer characterized by a high mortality rate after metastasis. Local chemotherapy could be considered a therapeutic approach only in stage 0 of progression (in situ melanoma) and in the postoperative phase after surgical removal of suspected skin lesions. For this purpose, drugs such as Imiquimod, 5-Fluorouracil, Dacarbazine, and Doxorubicin have been tested and shown positive effects. Recently, metal nanoparticles as separate therapeutic units or drug carriers have also fallen into the research focus.

Silver nanoparticles (AgNPs), in particular, are widely recognized as multifunctional tools in nanomedicine, drug delivery, and theranostics. They exert wide-spectrum antimicrobial and anti-tumor properties but their pharmacological effects are in a tight bond with the so-called “surface functionality”. For example, negatively charged and spherical particles are proven less toxic than positively charged particles, especially irregularly shaped (e.g., rods, wires, etc.). Still, because of this, the former are less potent anti-cancer agents.

Contemporary pharmaceutical development relies very much on eco-friendly technologies (often referred to as “green” technologies) that avoid the use of toxic solvents and reagents. This research has implemented one such method based on Camellia sinensis (green tea leaves) as a natural reducer of silver ions. To achieve enhanced antimicrobial and anti-tumor activity, the thus obtained AgNPs were further conjugated to chlorhexidine (Cx+) — a broad-spectrum antimicrobial agent and a cationic surfactant. Indeed, the AgNP-Cx+ complexes have shown highly increased antimicrobial properties, about 18-fold stronger anti-melanoma activity, and 3 times better tumor selectivity compared to the non-functionalized AgNPs.

The most valuable outcome of this new study, published in the journal Pharmacia, was the establishment of an adhesive patch prototype as a topical dosage form for the AgNP-Cx+ complex. The used polymers, Hydroxypropyl methylcellulose and Eudragit^® RS, demonstrated a lack of negative interference with the antiproliferative action of the active agent but also ensured twice as high activity and even better selectivity against the tumor cells.

Life cycle and climate adaptability of South Africa’s Cape autumn widow butterfly

A recent study published in the open-access journal African Invertebrates provides insights into the life history and behaviour of the endemic Cape autumn widow butterfly (Dira clytus), a species endemic to South Africa.

In the study, Silvia Mecenero of the Lepidopterists’ Society of Africa and Stephen Kirkman of Nelson Mandela University examine the species’ developmental stages and responses to environmental conditions, with implications for conservation efforts.

By rearing the subspecies Dira clytus clytus in controlled conditions, the researchers documented the butterfly’s complete life cycle, from egg to adult.

Two distinct pupation and adult emergence phases were identified over a period of a few months, influenced by cold temperatures, suggesting that environmental cues play a role in triggering these developmental events. The fact that two broods were found in a matter of months is interesting, because in the wild this species breeds only once a year.

The findings indicate that Dira clytus clytus could show some phenological plasticity in its response to climate change, by changing its timing of pupation and the number of broods within a year.

Such flexibility may not always be beneficial to butterflies, as shifts in phenology could lead to mismatches with the availability of their host plants. However, Dira clytus clytus is a generalist that feeds on a variety of grasses and may therefore be more adaptable to changes in its phenology.

The study was published as part of a commemorative collection of articles published in honour of the late ecologist Prof. Stefan H. Foord.

Slithering around in style.

Rhynchocalamus hejazicus is a recently discovered and secretive snake species from the Hejaz region of Saudi Arabia.

Upon the species’ discovery, researchers dubbed the stylish serpent “the missing piece of the puzzle” as it fills a large distribution gap for its genus.

The eyelash viper

Separating snake species.

An expedition into the jungles and cloud forests of Colombia and Ecuador revealed five dazzling new species of eyelash vipers, previously misidentified as one species.

Published in Evolutionary Systematics, the study received global attention from publications such as National Geographic thanks to the taxonomic importance and visual appeal of the research.

The shovel snake

Who ever said snakes can’t be cute?

Two species of African shovel-snout snakes, Prosymna confusa and Prosymna lisima, were published as new species in ZooKeys back in 2022.

Endemic to Angola, the snakes have unique beak-like snouts that allow them to dig into sandy soils. They also have backward pointed lancet-shaped teeth that they use for cutting open lizard eggs.

As they spend the majority of their time underground, these species were not the easiest to study, but they are certainly a treat for the eyes when they surface their wedge-shaped heads!
