European researchers have discovered a new species of osmiine bee with an unusual geographic distribution.
Hoplitis onosmaevae is currently found exclusively in the Mercantour National Park in the French Alps and disparate mountainous regions in Turkey and Northern Iraq. The distance of more than 2000 km between these areas highlights a significant biogeographic disjunction.

Described in the open-access journal Alpine Entomology, the new bee species demonstrates unique ecological characteristics such as its distinct nesting behaviour in dead wood.
Presumed to only harvest pollen from Onosma species, it has a long proboscis, which is likely an adaptation to collect nectar from the long-tubed flowers of this genus.

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

“The consideration of the few known populations of this species in France is very important in the conservation field,” says lead author Matthieu Aubert, freelance entomologist and member of the Observatoire des Abeilles association.
“This study highlights the incredible diversity of wild bees and that we still have a lot to learn from our environment, even in western Europe,” he continues.
The researchers emphasise the need for detailed conservation plans in the southwestern Alps to ensure the survival of Hoplitis onosmaevae, considering its highly specialised ecological niche and consequently its vulnerability to habitat changes. Their proposals for initial conservation steps can be found in the full research paper.

In a leap towards managing the ecological challenge posed by alien plant species, a recent study outlines a methodology for integrating and harmonising data on plant invasions across Australia.
Published in NeoBiota, the researchers created a standardised and unified database at the Australian national level, known as the Alien Flora of Australia, which will help monitoring and early-warning of alien flora, prevent species introduction, streamline decision-making, and bolster biosecurity efforts.

Focusing on Australia, a federally managed country, they identified mismatches in definitions and records of invasion status for vascular plant taxa across different jurisdictions. They then proposed prioritisation procedures to tackle those mismatches and to integrate information from ten data sources into a harmonised workflow at the national scale.
“The importance of harmonising terminology on biological invasions cannot be overstated. It is not merely an academic pursuit but a practical necessity, essential for realising meaningful advancements in invasion ecology.”
Dr Irene Martín-Forés
The authors recognise that the words used to describe alien species profoundly influence how humans perceive, study, and manage biological invasions. In federally managed countries, the problem is worse, as fragmented terminologies across different jurisdictions create confusion and inconsistencies in species classification and invasion statuses, therefore hindering effective communication among researchers, policymakers, and stakeholders.

The benefits of harmonising terminology on invasion ecology and combining contrasting data sources into a unified dataset at the Australian national scale extend far beyond semantic clarity. It enhances the accuracy of available datasets, and subsequently the reliability of scientific research focused on plant invasion. It also streamlines communication across jurisdictional borders and disciplines and empowers evidence-based decision-making in biosecurity management.
The workflow developed and its associated R script can be easily adapted to be used in any federally managed country, saving future efforts into trying to deal with inconsistencies in species’ invasion statuses.

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

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

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

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

At SpongeBoost, Pensoft is to take charge of the project’s identity, while building a strong network, and providing comprehensive knowledge and well-packaged information.
In recent years, Europe’s landscapes have become the victims of extreme events – ranging from floods to droughts – that have caused considerable damage to nature as well as human society.
With the aim to tackle such severe circumstances, the newly-started Horizon Europe-funded project SpongeBoost will be working towards protecting and promoting natural sponge landscapes.
Within SpongeBoost, the functional capacity of sponge landscapes is to be enhanced through building upon existing solutions and their large-scale implementation, but also through innovative approaches.
Pensoft is among the partnering institutions within SpongeBoost and serves as the leader of Work Package #5: “Communication, dissemination, exploitation, showcasing best practices and networking”. WP5 will aim to contribute to the project’s mission by building the overall project identity, building a strong network, and providing comprehensive knowledge and well-packaged information to targeted stakeholders.
The project
Funded by the European Union’s Horizon Europe research and innovation programme with a budget of EUR ~3 million, the project is coordinated by the Helmholtz Centre for Environmental Research (UFZ) and will be developed with the active participation of 10 partnering institutions from seven countries across Europe. Having been officially launched in January 2024, SpongeBoost is to wrap up in December 2027.
The project is part of the EU mission “Adaptation to Climate Change”, whose task is tosupport EU regions, cities and local authorities in their efforts to build resilience against the impacts of climate change.
“The protection and revitalisation of wetlands, particularly through peatland rewetting and river floodplain restoration, plays a central role in this,“
says project manager Mathias Scholz from the UFZ.
SpongeBoost held its official kick-off meeting in late February (2024) in Leipzig, Germany.
To officially kickstart the project, the first consortium meeting took place on 21-23 February in Leipzig, Germany. The kick-off meeting saw all 10 partnering institutions meet in person to officially lay the foundation of a promising collaboration that will flourish over the next four years.
The joint mission before the newly formed consortium is to enhance the natural sponge function of wetlands and soils in Europe, aligning with EU policies for climate adaptation, disaster risk reduction and biodiversity. To achieve that, the project plans to employ both bottom-up and top-down approaches, which will foster networking and synergy at the regional and EU level.
SpongeBoost will focus on five main objectives over the next four years:
Conduct a comprehensive literature review to create a standard reference catalogue for securing and enhancing sponge functions in adaptation to climate change. This catalogue will integrate social, economic, technical, and ecological effects and serve as a widely used resource across Europe and beyond.
Build a knowledge base on existing approaches for enhancing sponge functions, and highlight the reasons for success or failure. The goal is to enable regions and communities to replicate effective transformative solutions. Meanwhile, the consortium is to facilitate networking initiatives with other projects and identify suitable pilot sites for monitoring long-term success using the results of previous projects.
Work on the implementation, tests, refinement, and adjustment of best practices and innovative solutions through EU-wide case studies. The goal is to enhance climate resilience to extreme events and enable upscaling from local to EU levels.
Develop a roadmap with practical tools to empower stakeholders, drive transformative change, and integrate sponge solutions into regional, national and European climate adaptation processes to achieve EU Green Deal targets.
Connect communities and compile online resources for climate change adaptation. The goal is to facilitate access and combine a library of tools for restoration and share research findings on soil, water, and groundwater interconnection for replication across Europe.
In addition to leading the “Communication, dissemination, exploitation, showcasing best practices and networking” work package at SpongeBoost, Pensoft is to also assist the Environmental Action Germany (DUH) in the implementation of different innovative communications methods and ideas meant to support the project’s goals.
As part of the creative communication strategy, DUH will take the lead in the development of a “SpongeBooster superhero” character. By creating such a character that will be also featured in comics, the team will translate complex concepts into clear visuals and engaging narratives, thereby shaping the project’s visual identity and letting non-experts join the discourse. The Sponge Booster is to serve as an innovative method to disseminate project knowledge and address barriers with humour while fostering dialogue and avoiding potential conflicts.
International Consortium
The SpongeBoost project brings together a team of 10 partners from seven European countries, spanning research, policy, and management fields. The consortium members, who individually represent various restoration projects, will join forces and expertise to promote collaboration, knowledge exchange and synergies across European regions, to ultimately instil a lasting positive impact on sponge restoration for climate change adaptation.
Stay tuned for more project information on the SpongeBoost website coming soon at: www.spongeboost.eu/. In the meantime, you can follow SpongeBoost on social media on X and Linkedin.
The island of Cyprus, although considered a hotspot for biodiversity in the Mediterranean, is more famous for its beautiful sunny coasts than for its insect fauna. Nevertheless, some visitors of its highly populated beaches, with their observations and curiosity, have provided important information for a species never recorded before on the island: a giant water bug, also known as a toe biter.
Giant water bugs.
Scientists Michael Hadjiconstantis from the Association for the Protection of Natural Heritage and Biodiversity of Cyprus, Iakovos Tziortzis from the Ministry of Agriculture, Rural Development and Environment of Cyprus, and Kadir Boğaç Kunt from the Cyprus Wildlife Research Institute collected information and specimens from an increasing number of records of the giant water bug on the east coastline of the island in late spring and summer of 2020 and 2021. The species, known for inhabiting ponds and slowly moving freshwaters, had never been recorded on the island before, although established populations are known in adjacent Mediterranean countries such as Greece, Turkey, and Israel.
Locations of the reported Giant water bug sightings in Cyprus.
Also referred to as Electric light bug, this giant water bug is described as a vicious hunter, praying on invertebrates, fish, turtles, and even birds. What is even scarier, as the largest European true bug and the largest European water insect and measuring up to 12 cm, it has a reputation of inflicting very painful bites when handled carelessly.
A giant water bug found in Paralimni.
Its appearance, mainly on the eastern coastal front of the island, was initially recorded by swimmers, who were surprised by the fearsome looks and size of the bug. They either directly contacted the experts or published photos and videos online, mainly on Facebook groups related to biodiversity. The authors collected some of the specimens for further study. They also proceeded with an extensive online search on relevant online observation platforms (i.e. iNaturalist) in order to track any other reports of the species on the island. In addition, they sampled nearby wetlands, but did not spot the bug. End to end, a total of seven sightings were eventually recorded: five from social media and two after direct communication with the author team. Two specimens were obtained and examined morphologically to verify the species. The observations were recorded in a research article in the open-access journal Travaux du Muséum National d’Histoire Naturelle “Grigore Antipa”.

Having in mind that the toe biter is an iconic species accompanied by creepy stories concerning its encounters with humans, the authors assume that it is unlikely that it had gone unnoticed for too long. They consider it possible that several migration events might have been triggered in a short period of time by nearby countries hosting the species, such as Israel, Lebanon, and Syria. The specimens could have been transferred by wind or sea currents, as assumed by other researchers, or could have been driven by a decrease in food resources in their initial area of distribution.
Despite the number of recordings in a short timeframe, no conclusions can be drawn for the moment on the establishment of a population of the species on the island. This is further to be investigated, and as the initial recording of the species, citizen science can have an important role in this. The authors urge the public to be alert: “Naturalists looking for alien-like critters can provide valuable information on the presence and a possible establishment of the species through citizen science.” Until then, they warn: “Cypriots should keep their eyes open and their toes out of the water”.

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.
Tetranemertes bifrost
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.
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.
#NewSpecies! New crocodile newt from India just snuck in:
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.
I'm at a nerd convention today so here's the nerdiest frog I could find. Frog of the day is Hyloscirtus tolkieni, named for J. R. R. Tolkien. Photo is from the paper describing its recent discovery! https://t.co/DsQmzm7Np2pic.twitter.com/fpKBST6Uux
— LadyLasergun | Teatuber (@LadyLasergun) August 3, 2023
“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.
A comprehensive study of the floristic diversity of Agguttinni Territorial Park has documented 141 vascular plant, 69 bryophyte, and 93 lichen species from this unique protected area.
Encompassing over 16 000 km2 of towering mountains, long fiords, lush valleys, and massive ice caps, Agguttinni Territorial Park is a protected area on northern Baffin Island, Nunavut, Canada. This park, and all of Nunavut, is Inuit Nunangat – Inuit homeland in Canada – and the park protects sites and biodiversity stewarded by Inuit since time immemorial.
Agguttinni means “where the prevailing wind occurs” in the Inuktitut local dialect. The park includes important bird areas, key habitats for polar bears and caribou, and numerous important Inuit cultural sites. It is very remote: no roads lead to it, and access is only by helicopter, boat in the summer, or snowmobile in the winter.
Over five weeks in the summer of 2021, Dr. Gillespie’s team traveled across Agguttinni, exploring the vicinity of four base camps in the park on foot and further afield by helicopter. Across this large area, they studied many different habitats from the interior Barnes Ice Cap to the coast of Baffin Bay.
The heads of the long fiords, sheltered far inland, hosted the greatest plant diversity in the park, including numerous species rare on Baffin Island and two species previously only known from farther south in Canada: Lapland Diapensia (Diapensia lapponica) and Flame-tipped Lousewort (Pedicularis flammea). Conversely, the interior plateau near the ice cap was less diverse, but still held new records for Nunavut, such as Powdered Matchstick Lichen (Pilophorus caerulus), Starke’s Fork Moss (Kiaeria starkei) and Sprig Moss (Aongstroemia longipes).
This intensive fieldwork resulted in over a thousand new specimens deposited at the National Herbarium of Canada at the Canadian Museum of Nature and other herbaria worldwide. These pressed and preserved plants and lichens serve as proof that these species were found at this specific place and time and are the foundation for our knowledge of botanical diversity in the park.
Dr. Gillespie and her team also examined over 300 existing herbarium specimens from the park area, most of which were collected in 1950, the last time botanists intensively studied this part of Baffin Island. Combining data from these old and new specimens has resulted in an annotated checklist of the park’s plant and lichen diversity, describing the 141 vascular plant, 69 bryophyte, and 93 lichen species documented in Agguttinni, all native to the Arctic.
This checklist, immensely valuable to park managers and botanists, is filled with descriptions and photos useful to anyone interested in Arctic botany and is out now in the open-access, peer-reviewed journal Check List. With information on which species are present, where they are distributed, and which ones are rare, it will help the conservation and management of the protected area.

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).
Using a strong stakeholder co-development approach, these models will be combined in a One System framework for risk assessment and policy evaluation including an international long-term monitoring scheme for pollinators and pesticides.
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.
With an overall goal of reversing pollinator population declines and reducing the harmful impacts of pesticides, for the next four years, PollinERA will follow four specific objectives:
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.
Between 17 and 18 January 2024, experts from various realms of knowledge – from pollinator ecology, pesticide exposure and toxicological testing, to stakeholder engagement and communications – gathered in Aarhus, Denmark, to officially launch PollinERA. The two-day event seeded fruitful discussions on the project’s specific objectives, mission, methodology, outcomes and expected results.
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.
PollinERA’s coordinator Prof. Christopher J. Topping (The Social-Ecological Systems Simulation Centre, Aarhus University) gave a warm welcome during the kick-off meeting of the project in Aarhus, Denmark.
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.
Collaboration mechanisms between the PollinERA and the WildPosh projects include joint communication activities and events, joint data management strategy and alignment of activities to solidify the quality of final outputs.
Prof. Denis Michez (University of Mons), the coordinator of PollinERA’s sister-project WildPosh, presented the missions, objectives and methods, as well as the similarities, differences and collaboration potential between the two projects at PollinERA’s kick-off meeting in Aarhus, Denmark.
“It is fantastic that the European Commission puts so much effort into preserving wild pollinators and the countless benefits they bring to our society! The One System framework will hopefully become a fundamental part for the environmental risk assessment of chemicals for insect pollinators. I am really looking forward to implementing this insightful project, in close collaboration with its sister project WildPosh, where Pensoft is leading the dissemination efforts as well.”
says Teodor Metodiev, Principal Investigator for Pensoft at both PollinERA and WildPosh.
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.
A burrowing owl is overwintering on a Tennessee River peninsula near New Johnsonville, Tennessee, marking the first sighting of the species in the state.
STARKVILLE, Miss.—Birds migrating from north to south are a given but migrating from the southwest to the southeast is a little rarer. A burrowing owl is overwintering on a Tennessee River peninsula near New Johnsonville, Tennessee, marking the first sighting of the species in the state, and a Mississippi State wildlife ecologist is researching the fascinating oddity.
As the burrowing owl made its first home on a former Tennessee Valley Authority fossil fuel plant in 2020, Scott Rush, a scientist in the MSU Forest and Wildlife Research Center, was called in by TVA to study the bird of prey found hundreds of miles outside of its range.
“Burrowing owls are found west of Central Texas and Oklahoma, all the way up into Canada. There is also a non-migratory population in Florida, so you’ll occasionally see them in Alabama but never in Tennessee,” Rush said, explaining a continuing struggle for the birds is a loss of habitat.

“They live inside burrows created by prairie dogs and other animals,” he said. “They’re declining across the range in part because we’re losing some of those historic systems like undisturbed prairie dog colonies as more grasslands are being developed.”
Rush, an associate professor in MSU’s Department of Wildlife, Fisheries and Aquaculture, and his research team have studied the bird and its diet to learn more about where the novel creature came from and why he makes his winter home in the Volunteer State.

The team collected plumage from the owl’s feathers and determined it was a male belonging to the subspecies A.c. hypugaea. They studied pellets to determine its diet, identifying six different species including insect, mammalian and plant remnants. They also conducted an isotopic analysis of its feathers to determine the bird’s home range. Details from the sightings were recently published in Check List, a journal of biodiversity data.
“We could see from various kinds of elemental components that the bird is probably from Texas, relatively near Dallas, according to our analysis,” said Rush, who noted the bird has been banded and this year, scientists hope to outfit it with a GPS tracker. “If we can put a GPS tracker on the owl, we can confirm its home range.”
The owl, which again has overwintered this season in the same location, was first spotted by a TVA employee, and Liz Hamrick, a terrestrial zoologist with TVA reached out to Rush.
“A security guard at the site who happened to be an amateur birder came across it. Once I was alerted of its presence, I connected with our natural resources team who had already been working with Dr. Rush studying ospreys and vultures,” Hamrick said. “My role is to review TVA’s actions and ensure potential impacts to common wildlife and rare animals are avoided or minimized, and that includes protecting this owl. We need to make sure we follow all the state and federal laws, including the Endangered Species Act and the Executive Order for Migratory Birds.”
Hamrick said that as species assemblages change geographies, her team must be vigilant in identifying new species moving to the area like the burrowing owl and doing their best to protect them on TVA sites.
“It’s been exciting to learn about a whole new species and try to solve a mystery of why on earth this bird is repeatedly selecting to come to this industrial site out of its normal range,” she said.
