MAkiNg Technology work for moNitoring polliNAtors: Pensoft joins ANTENNA

Pensoft is to maximise the project’s impact by informing stakeholders about results and raising public awareness about pollinators.

Pensoft joins the newly funded Biodiversa+ project ANTENNA focused on making technology work for monitoring pollinators and is tasked with the communication, dissemination and exploitation activities.

The overarching goal of ANTENNA is to fill key monitoring gaps through advancing innovative technologies that will underpin and complement EU-wide pollinator monitoring schemes, and to provide tested transnational pipelines from monitoring activities to curated datasets and enhanced indicators that support pollinator-relevant policy and end-users.

The ANTENNA project answers the BiodivMon call, which was launched in September 2022 by Biodiversa+ in collaboration with the European Commission. The BiodivMon call sought proposals for three-year research projects to improve transnational monitoring of biodiversity and ecosystem change, emphasising innovation and harmonisation of biodiversity data collection and management methodologies, addressing knowledge gaps on biodiversity status and trends to combat biodiversity loss, and the effective use of existing biodiversity monitoring data.

Supporting the work of Work Package #5: “Project coordination, and communication”, Pensoft is dedicated to maximising the project’s impact by employing a mix of channels to inform stakeholders about the results from ANTENNA and raise public awareness about pollinators.

Pensoft is also tasked with creating and maintaining a clear and recognisable project brand, promotional materials, website, social network profiles, internal communication platform, and online libraries. Another key responsibility is the development, implementation and regular updates of the project’s communication, dissemination and exploitation plans, that ANTENNA is set to follow for the next four years.

On 14-15 March 2024, ANTENNA held its official kick off meeting. Project partners came together in Halle, Germany for two days to outline objectives, discuss strategies, and set the groundwork for this venture.

Specifically, the combined expertise of the consortium will address the following objectives:

Advance automated sample sorting and image recognition tools from individual prototypes to systems that can be adopted by practitioners
Expand pollinator monitoring to under-researched pollinator taxa, ecosystems, and pressures
Quantify the added value of novel monitoring systems in comparison and combination with ‘traditional’ methods in terms of cost effectiveness
Provide a framework for integrative monitoring by combining multiple data streams and. The framework will also support the development of near real-time forecasting models as bases for early warning systems;
Upscale local demonstrations into the implementation of large-scale transnational pipelines and provide context-specific guidance to the use of policy-makers and other users who might need to select monitoring methods and indicators.

Moving towards a systems-based Environmental Risk Assessment for wild bees, butterflies, moths and hoverflies: Pensoft joins PollinERA

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.

The European Green Deal, the EU biodiversity strategy, the EU zero pollution action plan, and the revised EU pollinators initiative all indicate the need to protect pollinators and address insect and pollinator declines.

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 mitigation beyond 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.

To support the proactive, open-science transfer of results and scientific achievements, two PollinERA topical collections of articles will be established in Pensoft’s Food and Ecological Systems Modelling Journal (FESMJ) and the Research Ideas and Outcomes (RIO) journal.

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.

In a joint effort to maximise impact and ensure sustainability of results, PollinERA will unfold in close collaboration with the sister Horizon Europe-funded project WildPosh, where Pensoft is also leading the Communication, dissemination and exploitation work package.

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.

Assessment, monitoring, and mitigation of chemical stressors on the health of wild pollinators: Pensoft joins WildPosh

Assessment, monitoring, and mitigation of chemical stressors on the health of wild pollinators: Pensoft joins WildPosh

Pensoft is amongst the participants of a new Horizon Europe project aiming to better evaluate the risk to wild pollinators of pesticide exposure, enhancing their health & pollination services.

Wild fauna and flora are facing variable and challenging environmental disturbances. One of the animal groups that is most impacted by these disturbances are pollinators, which face multiple threats, driven to a huge extent by the spread of anthropogenic chemicals, such as pesticides.

WildPosh (Pan-european assessment, monitoring, and mitigation of chemical stressors on the health of wild pollinators) is a multi-actor, transdisciplinary project whose overarching mission and ambition are to significantly improve the evaluation of the risk to wild pollinators of pesticide exposure, and enhance the sustainable health of pollinators and pollination services in Europe.

On 25 and 26 January 2024, project partners from across Europe met for the first time in Mons, Belgium and marked the beginning of the 4-year endeavour that is WildPosh. During the two days of the meeting, the partners had the chance to discuss objectives and strategies and plan their work ahead.

This aligns with the objectives of the European Green Deal and EU biodiversity strategy for 2030, emphasising the need to reduce pollution and safeguard pollinators. WildPosh focuses on understanding the routes of chemical exposure, evaluating toxicological effects, and developing preventive measures. By addressing knowledge gaps in pesticide risk assessment for wild pollinators, the project contributes to broader efforts in biodiversity conservation.

During the kick-off meeting in Mons, WildPosh’s project coordinator Prof. Denis Michez (University of Mons, Belgium) gave an introductory presentation.

As a leader of Work Package #7: “Communication, knowledge exchange and impact”, Pensoft is dedicated to maximising the project’s impact by employing a mix of channels in order to inform stakeholders about the results from WildPosh and raise further public awareness of wild and managed bees’ health.

Pensoft is also tasked with creating and maintaining a clear and recognisable project brand, promotional materials, website, social network profiles, internal communication platform, and online libraries. Another key responsibility is the development, implementation and regular updates of the project’s communication, dissemination and exploitation plans, that WildPosh is set to follow for the next four years.

“It is very exciting to build on the recently concluded PoshBee project, which set out to provide a holistic understanding of how chemicals affect health in honey bees, bumble bees, and solitary bees, and reveal how stressors interact to threaten bee health. WildPosh will continue this insightful work by investigating these effects on wild pollinators, such as butterflies, hoverflies and wild bee species, with the ultimate goal of protecting these small heroes who benefit the well-being of our planet,”
says Teodor Metodiev, WildPosh Principal Investigator for Pensoft.

For the next four years, WildPosh will be working towards five core objectives:

1) Determine the real-world agrochemical exposure profile of wild pollinators at landscape level within and among sites

2) Characterise causal relationships between pesticides and pollinator health

3) Build open database on pollinator traits/distribution and chemicals to define exposure and toxicity scenario

4) Propose new tools for risk assessment on wild pollinators

5) Drive policy and practice.

Consortium:

The consortium consists of 17 partners coming from 10 European countries. Together, they bring extensive experience in Research and Innovation projects conducted within the Horizon programmes, as well as excellent scientific knowledge of chemistry, modelling, nutritional ecology, proteomics, environmental chemistry and nutritional biology.

Scientists unravel the evolution and relationships for all European butterflies in a first

For the first time, a complete time-calibrated phylogeny for a large group of invertebrates is published for an entire continent. A German-Swedish team of scientists provide a diagrammatic hypothesis of the relationships and evolutionary history for all 496 European species of butterflies currently in existence. Their study provides an important tool for evolutionary and ecological research, meant for the use of insect and ecosystem conservation.

In a recent research paper in the open-access, peer-reviewed academic journal ZooKeys, a German-Swedish team of scientists provide a diagrammatic hypothesis of the relationships and evolutionary history for all 496 European species of butterflies currently in existence. Their study provides an important tool for evolutionary and ecological research, meant for the use of insect and ecosystem conservation.

In order to analyse the ancestral relationships and history of evolutionary divergence of all European butterflies currently inhabiting the Old continent, the team led by Martin Wiemers – affiliated with both the Senckenberg German Entomological Institute and the Helmholtz Centre for Environmental Research – UFZ, mainly used molecular data from already published sources available from NCBI GenBank, but also contributed many new sequences, some from very local endemics for which no molecular data had previously been available.

The phylogenetic tree also includes butterfly species that have only recently been discovered using molecular methods. An example is this Blue (*Polyommatus celina*), which looks similar to the Common Blue. It used to be mistaken for the Common Blue in the Canary Islands and the southwestern part of the Mediterranean Region.

Butterflies, the spectacular members of the superfamily Papilionoidea, are seen as an important proponent for nature conservation, as they present an excellent indicator group of species, meaning they are capable of inferring the environmental conditions of a particular habitat. All in all, if the local populations of butterflies are thriving, so is their habitat.

Furthermore, butterflies are pollinating insects, which are of particular importance for the survival of humans. There is no doubt they have every right to be recognised as a flagship invertebrate group for conservation.

While many European butterflies are seriously threatened, this one: Madeiran Large White (Pieris wollastoni) is already extinct. The study includes the first sequence of this Madeiran endemic which was recorded in 1986 for the last time. The tree demonstrates that it was closely related to the Canary Island Large White (Pieris cheiranthi), another threatened endemic butterfly, which survives only on Tenerife and La Palma, but is already extinct on La Gomera.

In recent times, there has been a steady increase in the molecular data available for research, however, those would have been only used for studies restricted either to a selected subset of species, or to small geographic areas. Even though a complete phylogeny of European butterflies was published in 2019, also co-authored by Wiemers, it was not based on a global backbone phylogeny and, therefore, was also not time-calibrated.

In their paper, Wiemers and his team point out that phylogenies are increasingly used across diverse areas of macroecological research, such as studies on large-scale diversity patterns, disentangling historical and contemporary processes, latitudinal diversity gradients or improving species-area relationships. Therefore, this new phylogeny is supposed to help advance further similar ecological research.

The study includes molecular data from 18 localised endemics with no public DNA sequences previously available, such as the Canary Grayling (Hipparchia wyssii), which is only found on the island of Tenerife (Spain).

A new hope: One of North America’s rarest bees has its known range greatly expanded

The Macropis Cuckoo Bee is one of the rarest bees in North America, partly because of its specialized ecological associations. It is a nest parasite of oil-collecting bees of the genus Macropis which, in turn, are dependent on oil-producing flowers of the genus Lysimachia.

In fact, the cuckoo bee – which much like its feather-bearing counterpart does not build a nest of its own, but lays its eggs in those of other species instead – is so rare that it was thought to have gone extinct until it was collected in Nova Scotia, Canada, in the early 2000s. As a result, the Macropis Cuckoo Bee was brought to the attention of the Committee on the Status of Endangered Wildlife in Canada (COSEWIC).

Recently, an individual reported from Alberta, Canada, brought new hope for the survival of the species. In addition to previously collected specimens from Ontario, this record greatly expands the known range of the cuckoo.

Scientists Dr Cory S Sheffield, Royal Saskatchewan Museum, Canada, who was the one to rediscover the “extinct” species in Nova Scotia, and Jennifer Heron, British Columbia Ministry of Environment & Climate Change Strategy, present their new data, and discuss the conservation status of this species in their paper, published in the open access journal Biodiversity Data Journal.

“This species has a very interesting biology,” they say, “being a nest parasite – or cuckoo – of another group of bees that in turn have very specialized dietary needs.”

The hosts, bees of the genus Macropis (which themselves are quite rare) are entirely dependent on plants of the primrose genus Lysimachia. Moreover, they only go after those Lysimachia species whose flowers produce oil droplets, which the insects collect and feed to their larvae. Thus, Macropis bees require these oil-producing flowers to exist just like Macropis cuckoo bees need their hosts and their nests. Curiously, this reliance, as suggested by previous studies on related European species, has made the female cuckoos develop the ability to find their host’s nests by the smell of the floral oils.

“This level of co-dependence between flower, bee, and cuckoo bee, makes for a very tenuous existence, especially for the cuckoo,” the authors comment. “The recent specimen from Alberta lets us know that the species is still out there, and is more widespread than we thought.”

In conclusion, the authors suggest that continuing to monitor for populations of rare bees, and documenting historic records, are crucial for conservation status assessments of at-risk species.

“Biodiversity Data Journal provides a great venue to share this type of information with our colleagues for regional, national, and international efforts for species conservation,” they note.

Claims that declines of pollinator species richness are slowing down in Europe revisited

Having conducted a thorough interpretation of the results of a recent study that inferred decrease in the biodiversity loss among pollinators across Europe, Dr Tom J. M. Van Dooren reveals that this conclusion cannot in fact be drawn. It is only supported for the bee fauna in the Netherlands. His study is published in the open access journal Nature Conservation.

Changes in pollinator abundances and diversity are of major concern. Pollinator diversity is quantified by their species richness: the number of species from a specific taxonomic group of pollinating animals present at a given time in a given area. A recent study, adopted in the recent UN IPBES Pollination Report draft summary, inferred that pollinator species richnesses are decreasing more slowly in recent decades in several taxonomic groups and European countries.

However, Dr Tom J. M. Van Dooren, affiliated with both Naturalis Biodiversity Center, the Netherlands, and the Institute of Ecology and Environmental Sciences of Paris, France, has now published his own study to show in detail the inaccuracies that the earlier conclusion has been based on.

Among other points, the scientist notes that the earlier study contained no explicit statistical comparisons between species richness changes in different periods. The earlier study also treated richness changes at country level and small spatial resolution as equivalent, while they probably represent different processes.

“Plants in Great Britain at the smallest spatial scales suggest a reduced rate of changes, but the results for larger spatial scales are not significant,” he illustrates. “The same holds for butterflies in the Netherlands.”

Dr Tom J. M. Van Dooren only finds support in the results of the earlier publication for a decelerating decline in bumblebees and other wild bees in the Netherlands. “This is in fact one taxon, the bees Anthophila, in a single country, the Netherlands”, he notes.

“The lack of robustness points again to the possibility that results found in the data can be due to changes in the shapes of species accumulation curves,” Dr Tom J. M. Van Dooren summarises. “Therefore the status of the statement on decelerating declines in the Pollination Report should be adjusted accordingly.”

Bee populations expanded during global warming after the last Ice Age

The Australian small carpenter bee populations appear to have dramatically flourished in the period of global warming following the last Ice Age some 18,000 years ago.

The bee species is found in sub-tropical, coastal and desert areas from the north-east to the south of Australia. Researchers Rebecca Dew and Michael Schwarz from the Flinders University of South Australia teamed up with Sandra Rehan, the University of New Hampshire, USA, to model its past responses to climate change with the help of DNA sequences. Their findings are published in the open access Journal of Hymenoptera Research.

“You see a rapid increase in population size from about 18,000 years ago, just as the climate began warming up after the last Ice Age,” says lead author Rebecca Dew. “This matches the findings from two previous studies on bees from North America and Fiji.”

“It is really interesting that you see very similar patterns in bees around the world,” adds Rebecca. “Different climate, different environment, but the bees have responded in the same way at around the same time.”

In the face of future global warming these finding could be a good sign for some of our bees.

However, the news may not all be positive. There are other studies showing that some rare and ancient tropical bees require cool climate and, as a result, are already restricted to the highest mountain peaks of Fiji. For these species, climate warming could spell their eventual extinction.

“We now know that climate change impacts bees in major ways,” says Rebecca, “but the challenge will be to predict how those impacts play out. They are likely to be both positive and negative, and we need to know how this mix will unfold.”

Bees are major pollinators and are critical for many plants, ecosystems, and agricultural crops.
