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:

  1. 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.
  2. Develop and test a co-monitoring scheme for pesticides and pollinators across European cropping systems and landscapes, developing risk indicators and exposure information.
  3. Develop models for predicting pesticide toxicological effects on pollinators for chemicals and organisms, improve toxicokinetic/toxicodynamic (TKTD) and population models, and predict environment fate.
  4. 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.

Earth Observation meets in-situ biodiversity monitoring: Pensoft joins the OBSGESSION project

As a leader of the Work Package 6: “Dissemination, Multi-stakeholder outreach and synergies,” Pensoft is tasked to build an involved community around OBSGESSION.

Pensoft is to contribute to the OBSGESSION consortium with expertise in science communication by taking care of stakeholders engagement, thereby supporting its goal of improved terrestrial and freshwater biodiversity monitoring. As a leader of the Work Package 6: “Dissemination, Multi-stakeholder outreach and synergies,” Pensoft is tasked to build an involved community around OBSGESSION.

Terrestrial and freshwater biodiversity has been declining at an alarming rate due various factors such as intensification of anthropogenic activities and climate change.

To help protect and preserve precious ecosystems, the new research project OBSGESSION (Observation of Ecosystem Changes for Action) launched, jointly funded under the EU programme Horizon Europe, the UK Research and Innovation (UKRI) and the University of Zurich (UZH). 

Coordinated by the Finnish Environmental Institute (Syke), OBSGESSION aims to reveal the drivers of biodiversity loss, pinpoint important indicators of ecosystem health and inform sustainability policy.

The project

OBSGESSION launched in January 2024 and will wrap up in December 2027 with the support of ~7.3 million EUR of funding, provided by the European Union’s Horizon Europe program, The UK Research and Innovation program (UKRI), and the University of Zurich (UZH).

The OBSGESSION consortium at the kick-off meeting in January 2024 (Tuusula, Finland).

The project officially kicked off with the first consortium meeting in Tuusula, Finland, between 30th January and 2nd February.

For the coming four years, the joint mission before the newly formed consortium is to integrate biodiversity data sources, such as Earth Observation, with in-situ research, and also cutting-edge ecological models. These will all be made into a comprehensive product for biodiversity management in both terrestrial and freshwater ecosystems. 

The project will also spearhead an innovative approach for assessing Essential Biodiversity Variables (EBVs) and their resilience to errors. Through purposely propagating error into biodiversity estimates and comparing the resulting models with ones using correct estimates, the EBV case studies aim to investigate model uncertainties and identify approaches that are more sensitive. Thus, they will inform policy and management about the optimal EBVs, and their key thresholds for conservation.

To demonstrate the implementation of the techniques and methodologies they are to develop within the project; and to respond to the needs of the EU Biodiversity Strategy for 2030, the consortium will focus on six distinct pilot activities:

  1. Investigating and predicting biodiversity change in the European Alps: multi-scale, multi-modal and multi-temporal investigation using remote and in-situ data integration.
  2. Improving habitat classification models: going beyond state-of-the-art in terms of accurate high-resolution mapping of Europe’s habitats, powered by machine learning.
  3. Forecasting ecosystem productivity under disturbances & climate change: incorporating remote sensing EBVs to assess metrics of ecosystem structure and health.
  4. Supporting temperate and boreal forest protection & restoration: through assessing ecosystem conditions via eDNA & image spectroscopy.
  5. Monitoring freshwater ecosystems under disturbances & climate change: utilizing the novel Thematic Ecosystem Change Indices (TECIs).
  6. Ecosystem functioning of the Kokemäenjoki estuary – assessing freshwater & transitional water quality incorporating both in-situ and Earth Observation data.

Through its pilot studies, methodological assessments, data stream integration, and investigating land use cover changes across Europe, OBSGESSION will help improve our understanding of ecosystem vulnerability across a range of specific habitat types, identify drivers and pressures to ecosystem change and improve planning and prioritization of restoration measures.

“At Pensoft, we are eager to be part of the bright OBSGESSION consortium and look forward to offering our expertise and experience in raising awareness towards the project and contributing to the high impact of the resulting outputs, methodologies and policy recommendations that aim to strengthen our understanding of biodiversity change,”

says Gabriela Popova, science communicator at Pensoft and leader of the Work Package #6: “Dissemination, Multi-stakeholder outreach and synergies” at OBSGESSION.

International Consortium

The interdisciplinary OBSGESSION consortium consists of 11 partnering organisations from seven European countries, who bring diverse expertise spanning from remote sensing and Earth observation, to freshwater ecosystems, programming and science communication. Many partners represent acclaimed scientific institutions with rich experience in collaborative EU projects.

Brand new journal Estuarine Management and Technologies streamlines innovation in ecosystems conservation

There has been an increasing need to support the exchange of research related to the conservation and sustainable management of estuarine ecosystems by means of new-age technologies and approaches.

Where freshwater rivers meet seas and oceans lies a scientifically intriguing and ecologically important type of ecosystem. As estuarine ecosystems provide various and diverse services to humanity and the planet at large, including food security and natural buffers and filters in the events of storms and water pollution, there has been an increasing need to facilitate and support the exchange of research findings and ideas related to their conservation and sustainable management by means of new-age technology and novel approaches.

This is how a team of renowned and passionate scientists, headed by Dr. Soufiane Haddout (Ibn Tofail University, Morocco), took the decision to launch a brand new open-access, peer-reviewed scholarly, aptly titled Estuarine Management and Technologies. They explain the rationale behind the journal in a new editorial, published to mark the official launch of the journal.

Having already worked closely with the scientific publisher and technology provider Pensoft on the fine touches of the concept of the new academic title, the team opted to use Pensoft’s publishing platform of ARPHA. As a result, the new journal provides a seamless, end-to-end publishing experience, encompassing all stages between manuscript submission and article publication, indexation, dissemination and permanent archiving. 

Within the collaboration between the journal’s and Pensoft’s teams, Estuarine Management and Technologies will take advantage of various services offered by the ARPHA platform, including full-text automated export in machine-readable and minable JATS-XML format to over 60 relevant databases for scientific literature and data; semantically enriched and multimedia-friendly publications accessible in HTML; and rich statistics about the outreach and usage of each published article and its elements (e.g. figures and tables), including views, downloads, online mentions, and citations. 

The publishing platform’s in-house indexing team will continue their close work with the journal’s editors to ensure that the scholarly outlet retains highest quality and integrity, so that it covers the criteria for indexation at additional key databases that require individual evaluation. In the meantime, ARPHA’s technical and editorial teams will provide technical and customer support to authors, editors and reviewers. The marketing and promotion team of ARPHA will be also joining forces with the journal to boost the visibility and image of the new academic title.

During the launch phase, content accepted for publication following double-blinded peer review will be made public right away for free to both authors and readers, where the journal will be operating under a continuous publication model.

Estuarine Management and Technologies welcomes studies from a wide spectrum of disciplines, including physics, chemistry, geology, biology, and hydrology, with a focus on interdisciplinarity, multifaceted approaches and holistic perspectives.

“One crucial aspect of estuarine management is the sustainable use of resources to balance conservation with human needs. Striking this delicate equilibrium requires a holistic understanding of the intricate web of ecological interactions within estuarine environments. Advanced technologies, such as isotopic techniques, environmental DNA (eDNA) analysis, can provide insights into the biodiversity of estuarine ecosystems with unprecedented precision,”

explain Dr Haddout and his colleagues in the opening editorial.

Amongst the unique features of the new journal are several additional publication types, such as Expert View, Video Paper, Rapid Communication, Mini Review and Estuarine Scientists, where these have been added to traditional publication outputs (e.g. Research Paper, Review Paper, Data Paper) to foster collaboration between researchers and other stakeholders in the field.

The journal is also running an annual Trailblazing Talent in Estuarine Management and Technologies award intended to recognise and encourage young scientists and engineers at the forefront of cutting-edge research in estuarine management and technologies. Nominations and applications are currently open.

Estuarine Management and Technologies also welcomes applications for guest editors in order to further expand the journal and its immediate expert network.

“I am delighted to see the Estuarine Management and Technologies journal already live on the ARPHA platform. We are confident that this particularly important, yet so far quite overlooked area of study will greatly benefit from this highly promising journal,”

says Prof. Lyubomir Penev, CEO and founder of Pensoft and ARPHA.

“I am pleased to announce the launch of the Estuarine Management and Technologies journal on ARPHA, a decision rooted in our commitment to advancing the field. We believe that this strategic partnership will not only enhance the visibility and accessibility of our journal, but will also foster collaboration and innovation within the estuarine management and technologies community. We expect this alliance to be a catalyst for scholarly excellence, providing a robust platform for researchers and practitioners to share insights, address challenges, and propel the field forward. Together with ARPHA, we are confident in the positive impact our journal will have on shaping the future of estuarine management and technologies.”

says Dr. Soufiane Haddout, Editor-in-Chief and founder, Estuarine Management and Technologies.

One Ecosystem selected for inclusion in the Web of Science

“Not only does it mean that content is persistent in merit and quality, but that innovative research outputs are already appreciated within academia,” says Editor-in-Chief Prof Dr Benjamin Burkhard

Seven years after its official launch in May 2016, the One Ecosystem journal has successfully completed the rigorous quality and integrity assessment at Web of Science.

Scientific papers published in One Ecosystem from 2021 onwards will be indexed at the Emerging Sources Citation Index (ESCI) and the Journal Citation Reports (JCR), revealed the Indexing team at ARPHA Platform.

The news means that One Ecosystem might see its very first Journal Impact Factor (JIF) as early as 2024, following the latest revision of the metric’s policies Clarivate announced last July. According to the update, all journals from the Web of Science Core Collection are now featured in the Journal Citation Reports, and thereby eligible for a JIF.

“Giving all quality journals a Journal Impact Factor will provide full transparency to articles and citations that have contributed to impact, and therefore will help them demonstrate their value to the research community. This decision is aligned to our position that publications in all quality journals, not just highly cited journals, should be eligible for inclusion in research assessment exercises,” said back then Dr Nandita Quaderi, Editor-in-Chief and Editorial Vice President at Web of Science.

“We are happy to learn that Web of Science has recognised the value and integrity of One Ecosystem in the scholarly landscape. Not only does it mean that the scientific content One Ecosystem has been publishing over the years is persistent in merit and quality, but that innovative research outputs are already widely accepted and appreciated within academia.

After all, one of the reasons why we launched One Ecosystem and why it has grown to be particularly distinguished in the field of ecology and sustainability is that it provides a scholarly publication venue for traditional research papers, as well as ‘unconventional’ scientific contributions,”

comments Prof Dr Benjamin Burkhard, Executive Director at the Institute of Physical Geography & Landscape Ecology, Leibniz University Hannover (Germany) and founding Editor-in-Chief of One Ecosystem.

“These ‘unconventional’ research outputs – like software descriptions, ecosystem inventories, ecosystem service mappings and monitoring schema – do not normally see the light of day, let alone the formal publication and efficient visibility. We believe that these outputs can be very useful to researchers, as well as practitioners and public bodies in charge of, for example, setting up indicator frameworks for environmental reporting,”

says Prof Davide Geneletti, Department of Civil, Environmental and Mechanical Engineering of University of Trento, Italy, and Deputy Editor-in-Chief of One Ecosystem.

“In fact, last year, we also launched a new article type: the Ecosystem Accounting table, which follows the standards set by the the System of Environmental-Economic Accounting Ecosystem Accounting (SEEA EA). This publication type provides scientists and statisticians with a platform to publish newly compiled accounting tables,” 

adds Dr Joachim Maes, Policy analyst at the Directorate-General for Regional and Urban Policy of the European Commission and Deputy Editor-in-Chief of One Ecosystem.

***

Previously, One Ecosystem has been accepted for indexing at over 60 major academic databases, including Scopus, DOAJ, Cabell’s Directory, CABI and ERIH PLUS. In June 2022, the journal received a Scopus CiteScore reading 7.0, which placed it in Q1 in five categories: Earth and Planetary Sciences; Ecology; Nature and Landscape Conservation; Agricultural and Biological Sciences (miscellaneous); Ecology, Evolution, Behavior and Systematics.

Redefining nature-based decision-making: Pensoft joins EU project SELINA

“Ecosystem services is one of the topics that Pensoft has been involved in for over 10 years,” points out COO Prof Pavel Stoev.

Ambitious goals have been set by the European Union, in order to tackle the biodiversity conservation challenges over the coming decade. No less ambitious are the goals of the Horizon Europe project SELINA, which is one of the current major initiatives looking in the same direction. 

SELINA (Science for Evidence-based and Sustainable Decisions about Natural Capital) is a transdisciplinary project aimed at promoting the conservation of biodiversity, enhancing ecosystem conditions, and supporting the sustainable use of the environment through evidence-based decision-making.

As an experienced science communicator and open-science publisher, Pensoft will be leading the project’s communication and dissemination activities.

“Ecosystem services is one of the topics that Pensoft has been involved in for more than 10 years, so it was only natural for us to continue our work as a communicator of scientific information in the ambitious SELINA project as well,”

says Prof Pavel Stoev, COO at Pensoft.

“We have already collaborated with many of the partners within the earlier EC Horizon 2020 project ESMERALDA, which concluded with the launch of a pan-European network of scientific institutions engaged with biodiversity conservation and ecosystem services.

In addition, Pensoft has been strongly connected to the community through the scholarly journal One Ecosystem, which is supported by Ecosystem Services Partnership, and offers an opportunity for scientists in the field to publish their results in a new and innovative way.”

he adds.

The project

SELINA was launched in July 2022 and will run for 5 years. Having received EUR 13 million in funding, the project is seen as an unprecedented opportunity for smart, cost-effective, and nature-based solutions to historic societal challenges such as climate change, biodiversity loss, and food security. 

One of the project’s main objectives is to identify biodiversity, ecosystem condition, and ecosystem service factors that can be successfully integrated into decision-making processes in both the public and private sectors. 

To achieve this objective, SELINA will develop, test, and integrate new and existing knowledge, including methodological approaches to improve biodiversity, ecosystem condition, and ecosystem service information uptake by decision-makers. 

In addition, the project will utilise EU-wide workshops and multi-disciplinary Communities of Practice involving a wide range of stakeholders, including scientists, policymakers, business leaders, and civil society organisations. 

The project will also organise Demonstration Projects on biodiversity, ecosystem condition, and ecosystem service integration in decision-making and co-create a Compendium of Guidance that will allow stakeholders to make full use of the project’s results and fit-for-purpose recommendations with real-world applications in policy-making and business decisions. 

International consortium

SELINA project brings together experts from 50 partnering organisations across all European Union member states, Norway, Switzerland, Israel, and the United Kingdom.

The project comprises a Pan-European and transdisciplinary network of professionals from the academic and non-academic sectors with various (inter)disciplinary backgrounds – including ecologists, economists, social scientists – who have agreed to work collaboratively to support transformative change based on evidence-based decision-making related to the management of natural resources.

Citizen scientists help expose presence of invasive Asian bamboo longhorn beetle in Europe

A worryingly high number of Asian bamboo longhorn beetles turn out to have been emerging across Europe for about a century already, finds an international research team. Curiously, the records of the invasive, non-native to the Old Continent species are mostly sourced from citizen scientists and online platforms, which proves the power of involving the public in species monitoring. The study is published in the open-access, peer-reviewed scientific journal BioRisk.

A worryingly high number of Asian bamboo longhorn beetles (Chlorophorus annularis) turn out to have been emerging across Europe for about a century already, finds an international research team, headed by researchers from the Center of Natural History, University of Hamburg, Germany. Curiously, the recent records of the invasive, non-native to the Old Continent species are mostly sourced from citizen scientists and online platforms, which proves the power of involving the public in species monitoring. The study is published in the open-access, peer-reviewed scientific journal BioRisk.

In our globalised world, which has already become victim to climate change and biodiversity loss, non-native species present a further threat to our ecosystems. Thus, the rising accounts of newly recorded alien species are of serious concern to both scientists and (inter)national institutions. However, surveying non-native species remains limited to a small fraction of species: those known to be particularly invasive and harmful.

One of the multitude of non-native species that are currently lacking efficient and coordinated surveying efforts is the Asian bamboo longhorn beetle (Chlorophorus annularis). Naturally occurring in temperate and tropical Southeast Asia, the insect feeds on a variety of plants, but prefers bamboo. Thus, due to the international trade of bamboo and the insects ‘travelling’ with the wood, the species has continuously been expanding its distribution around the world. Its first appearance in Europe was recorded back in 1924, when it was identified in England.

Back to our days, during a fieldwork practice for students at the University of Hamburg, held within the city because of the COVID-19 travelling restrictions, the team stumbled across a longhorn beetle, later identified by scientists as the Asian bamboo borer. Furthermore, it became clear that there were even more recent records published across different citizen science platforms, such as iNaturalist, iRecord and Waarneming.nl. Having taken the contacts of the citizen scientists from there, the researchers approached them to ask for additional collection details and images, which were readily provided. As a result, the researchers formally confirmed the presence of the Asian bamboo borer in Belgium and the Netherlands. In total, they reported thirteen new introductions of the species in Europe, which translates to a 42% increase of the records of the species for the continent.

“In light of the warming climate and a growing abundance of ornamental bamboo plants in Europe, the beetle might get permanently established. Not only could it become a garden pest, but it could also incur significant costs to the bamboo-processing industry,”

comments Dr Matthias Seidel, lead author of the study.

Having realised the potential of citizen science for bridging the gaps in invasive species monitoring, the researchers now propose for specialised platforms to be established with the aim to familiarise non-professional scientists with non-native species of interest and provide them with more sophisticated reporting tools. The aim is to speed up the identification of important alien species by collating records of specific species of interest, which are flagged and regularly exported from other citizen science databases and platforms.

Failure to respond to a coral disease epizootic in Florida: causes and consequences

By 2020, losses of corals have been observed throughout Florida and into the greater Caribbean basin in what turned out to be likely the most lethal recorded case of Stony Coral Tissue Loss Disease. A Perspectives paper, published in the open-access peer-reviewed journal Rethinking Ecology, provides an overview of how Florida ended up in a situation, where the best that could be done is rescuing genetic material from coral species at risk of regional extinction.

Dredging projects conducted in association with coral reefs typically generate concern by environmental groups, resulting in careful monitoring by government agencies. Even though the aim of those dredge projects is to widen or deepen existing ship channels, while minimizing damage to coral reef resources, there are often the intuitive negative assumptions that dredging kills corals.

The recent Port Miami Dredge Project started as an uncomplicated case story. However, significant problems arose, caused by a concurrent and unprecedented coral disease epidemic that killed large numbers of corals, which was initiated following a regional thermal anomaly and coral bleaching event.

The coral disease, known as Stony Coral Tissue Loss Disease (SCTLD), was first observed in September 2014 near Virginia Key, Florida. In roughly six years, the disease has spread throughout Florida and into the greater Caribbean basin. The high prevalence of SCTLD and the resulting high mortality in coral populations, coupled with the large number of susceptible species affected, suggest that this disease outbreak is one of the most lethal ever recorded on contemporary coral reefs. The disease is still presently active and continues to ravage coral reefs throughout the region.

The initial response to this catastrophic disease by resource managers with purview over the ecosystem in Southeast Florida was slow. There is generally a noticeably short window of opportunity to intervene in disease amelioration or eradication in the marine environment. This slow response enabled the disease to spread unchecked. Why was the response to the loss of our coral reefs to a coral disease epidemic such a massive failure? This includes our failure as scientists, regulators, resource managers, local media, and policy makers alike. With this Perspectives paper, published in Rethinking Ecology, my intention was to encapsulate the numerous reasons for our failures during the first few years of the outbreak, reminiscent of the early failures in the U.S. response to the COVID-19 pandemic.

First, the Port Miami dredging project was ongoing when the coral disease epidemic began. Some managers and local environmental groups blamed dredging, rather than SCTLD for the coral losses, reported in the project’s compliance monitoring program. Second, this blame was amplified in the media, because dredging projects are intuitively assumed to be bad for coral reefs. Third, during this same time, the State of Florida prohibited government employees from acknowledging global warming in their work. This was problematic because ocean warming is a proximal cause of many coral diseases.

As a result, some managers ignored the well-known links between warming and coral disease. A consequence of this policy was that the dredging project provided an easy target to blame for the coral mortality noted in the monitoring program, despite convincing data that suggested otherwise. 

Specifically, the intensive compliance monitoring program, conducted by trained scientific divers, was statistically significant. SCTLD that was killing massive numbers of corals throughout the region was also killing corals at the dredge site. Further, this was happening in the same proportions and among the same suite of species. 

Finally, when the agencies responded to the outbreak, their efforts were too little and much too late to make a meaningful difference. While eradication of the disease was never a possibility, early control measures may have slowed its spread, or allowed for the rescue of significant numbers of large colonies of iconic species. Because of the languid management response to this outbreak, we are now sadly faced with a situation where much of our management efforts are focused on the rescue of genetic material from coral species already at risk of regional extinction.

The delayed response to this SCTLD outbreak in Southeast Florida has many similarities to the COVID-19 pandemic response in the United States and there are lessons learned from both that will improve disease response outcomes in the future, to the benefit of coral reefs and human populations.

Eurasian eagle owl diet reveals new records of threatened giant bush-crickets

Bird diets provide a real treasure for research into the distribution and conservation of their prey, conclude scientists after studying the Eurasian Eagle Owl in southeastern Bulgaria. In their paper, published in the open-access, peer-reviewed journal Travaux du Muséum National d’Histoire Naturelle “Grigore Antipa”, they report the frequent presence of the threatened Big-Bellied Glandular Bush-Cricket, and conclude that studies on the Eurasian Eagle Owl could be used to identify biodiversity-rich areas in need of protection.

Bird diets provide a real treasure for research into the distribution and conservation of their prey, such as overlooked and rare bush-cricket species, point out scientists after studying the diet of the Eurasian Eagle Owl (Bubo bubo) in southeastern Bulgaria.

In their paper, published in the open-access, peer-reviewed journal Travaux du Muséum National d’Histoire Naturelle “Grigore Antipa”, Dr Dragan Chobanov (Institute of Biodiversity and Ecosystem Research, Bulgaria) and Dr Boyan Milchev (University of Forestry, Bulgaria) report the frequent presence of the threatened with extinction Big-Bellied Glandular Bush-Cricket (Bradyporus macrogaster) in the diet of Eurasian Eagle Owls, and conclude that the predatory bird could be used to identify biodiversity-rich areas in need of protection.

While the Balkan Peninsula has already been recognised as the area with the highest diversity of orthopterans (grasshoppers, crickets and bush-crickets) in Europe and one of the generally most biologically diverse areas in the whole Palearctic realm, it is also home to a worrying number of threatened species. Additionally, a thorough and updated country assessment of the conservation status of the orthopterans found in Bulgaria is currently lacking. This is why the Bulgarian team undertook a study on the biodiversity of these insects by analysing food remains from pellets of Eurasian Eagle Owls, collected from 53 breeding sites in southeastern Bulgaria.

As a result, the scientists reported three species of bush crickets that have become a significant part of the diet of the studied predatory birds. Curiously enough, all three species are rare or threatened in Bulgaria. The case of the Big-Bellied Glandular Bush-Cricket is of special concern, as it is a species threatened by extinction. Meanwhile, the local decline in mammals and birds that weigh between 0.2 and 1.9 kg, which are in fact the preferred prey for the Eurasian Eagle Owl, has led the highly opportunistic predator to increasingly seek large insects for food. The researchers even suspect that there might be more overlooked species attracting the owls.

Taking into account the hereby reported interconnected inferences of conservation concern, as well as the vulnerability of the Big-Bellied Glandular Bush-Cricket, a species with a crucial role in the food chain, the scientists call for the newly provided data to prompt the designation of a new Natura 2000 site. Additionally, due to the species’ requirements for habitats of low disturbance and high vegetation diversity, and its large size and easy location via singing males, they point out that it makes a suitable indicator for habitat quality and species community health.

Scientists took a rare chance to prove we can quantify biodiversity by ‘testing the water’

Recent study conducted at a UK fishery farm provides new evidence that DNA from water samples can accurately determine fish abundance and biomass

Organisms excrete DNA in their surroundings through metabolic waste, sloughed skin cells or gametes, and this genetic material is referred to as environmental DNA (eDNA).

As eDNA can be collected directly from water, soil or air, and analysed using molecular tools with no need to capture the organisms themselves, this genetic information can be used to report biodiversity in bulk. For instance, the presence of many fish species can be identified simultaneously by sampling and sequencing eDNA from water, while avoiding harmful capture methods, such as netting, trapping or electrofishing, currently used for fish monitoring.

While the eDNA approach has already been applied in a number of studies concerning fish diversity in different types of aquatic habitats: rivers, lakes and marine systems, its efficiency in quantifying species abundance (number of individuals per species) is yet to be determined. Even though previous studies, conducted in controlled aquatic systems, such as aquaria, experimental tanks and artificial ponds, have reported positive correlation between the DNA quantity found in the water and the species abundance, it remains unclear how the results would fare in natural environments.

However, a research team from the University of Hull together with the Environment Agency (United Kingdom), took the rare opportunity to use an invasive species eradication programme carried out in a UK fishery farm as the ultimate case study to evaluate the success rate of eDNA sampling in identifying species abundance in natural aquatic habitats. Their findings were published in the open-access, peer-reviewed journal Metabarcoding and Metagenomics.

“Investigating the quantitative power of eDNA in natural aquatic habitats is difficult, as there is no way to ascertain the real species abundance and biomass (weight) in aquatic systems, unless catching all target organisms out of water and counting/measuring them all,”

During the eradication, the original fish ponds were drained and all fish, except the problematic invasive species: the topmouth gudgeon, were placed in a new pond, while the original ponds were treated with a piscicide to remove the invasive fish. After the eradication, the fish were returned to their original ponds. In the meantime, all individuals were counted, identified and weighed from experts, allowing for the precise estimation of fish abundance and biomass.

“We then carried out our water sampling and ran genetic analysis to assess the diversity and abundance of fish genetic sequences, and compared the results with the manually collected data. We found strong positive correlations between the amount of fish eDNA and the actual fish species biomass and abundance, demonstrating the existence of a strong association between the amount of fish DNA sequences in water and the actual fish abundance in natural aquatic environments,”

reports Di Muri.

The scientists successfully identified all fish species in the ponds: from the most abundant (i.e. 293 carps of 852 kg total weight) to the least abundant ones (i.e. one chub of 0.7 kg), indicating the high accuracy of the non-invasive approach.

“Furthermore, we used different methods of eDNA capture and eDNA storage, and found that results of the genetic analysis were comparable across different eDNA approaches. This consistency allows for a certain flexibility of eDNA protocols, which is fundamental to maintain results comparable across studies and, at the same time, choose the most suitable strategy, based on location surveyed or resources available,”

elaborates Di Muri.

“The opportunity of using eDNA analysis to accurately assess species diversity and abundance in natural environments will drive a step change in future species monitoring programmes, as this non-invasive, flexible tool is adaptable to all aquatic environments and it allows quantitative biodiversity surveillance without hampering the organisms’ welfare.”

Guest Blog Post: Researchers split the birdcatcher trees (genus Pisonia) into three

The birdcatcher trees – genus Pisonia – are infamous for trapping birds with their super-sticky seed pods that would frequently entangle the body of the ‘victim’. Left flightless, the poor feathered creatures eventually die either from starvation or fatigue, or predators. Similarly notorious are the birdcatcher trees for botanists, who have been baffled by their complicated classification for the last three centuries. 

Here’s why myself and graduate student Elson Felipe Rossetto of the Universidade Estadual de Londrina (Brazil) decided to take up the untangling of this issue with our recent taxonomic studies. You can find our research paper published in the open-access scholarly journal PhytoKeys.

We reestablished two genera: Ceodes and Rockia, where both had been previously merged under the name of Pisonia. Now, as a result, there are three distinct lineages of birdcatcher trees from the islands of the Pacific and Indian Oceans: Ceodes, Pisonia, and Rockia.

“Previous molecular studies on Pisonia species from around the world showed that species were clustered into three major groups, and here we assign names for each of them. With this new classification, a large number of the species known as Pisonia will be henceforth named Ceodes. This includes the Parapara (Ceodes brunoniana) and the Birdlime (Ceodes umbellifera) trees, both native to many islands, including Hawaii and New Zealand. They are commonly planted in gardens for their lush and sometimes variegated foliage, as well as their fragrant white flowers. However, the Cabbage tree (Pisonia grandis) will still be technically known as Pisonia.”

Birdcatcher trees have generated much controversy in the popular media because of their seed pods (technically called “anthocarps”) secreting a sticky substance that glues them to the feathers of seabirds or other animals for dispersal. Sometimes, though, too many seed pods can harm or kill birds, especially small ones, by weighing them down and rendering them flightless. This macabre practice has led to many controversies and local campaigns aiming to remove the trees, even illegally.

In spite of their forbidding reputation, however, we would like to stress that birdcatcher trees have positive effects on ecosystems and are important components of vegetation, especially for small islands. Sadly, there are many endemic and already endangered species of birdcatcher trees that only exist on a few small islands, where they are effectively placed at the mercy of local people.

Many species of birdcatcher trees are large and, thereby, tolerate harsh environments like seafronts and rocky cliffs, making them prime nesting spots for seabirds. Birdcatcher trees are also ecologically curious and could be regarded as keystone species in small islands, because their soft branches can sustain many types of invertebrates; their flowers are an important food source for bees and ants; their dense leaf litter nourishes the soil; and their roots have intimate interaction with native underground fungi (mycorrhiza).

All in all, clarifying the taxonomy of the birdcatcher trees is the first step to understanding how many species exist and how they relate to each other. 

Although most people relate birdcatcher trees with beaches and coastal habitats, there are species that are only found in mountains or rainforests. For example, the species now allocated to the genus Rockia is endemic to the Hawaiian archipelago. These are small trees able to grow in dry to mesic mountain forests. Using our new classification, future studies can explore in detail the hidden diversity of these enigmatic plants, and find out how trees with high dispersal capabilities evolve into species endemic to small island ecosystems.
