Research stations across Europe presented in a photo exhibition in Sofia

The exhibition was organised by Pensoft as part of the communication and dissemination activities for the EC Horizon project eLTER (European Long-Term Ecosystem Research)

In the past months, a unique photo exhibition showcasing European long-term ecosystem research sites was presented in the Bulgarian capital: Sofia.

This visually striking exhibition was not only a celebration of science and nature, but also an illustrative example of Pensoft’s integrated approach to communication, dissemination, and community engagement under the EU-funded eLTER project.

Coordinated by Pensoft’s Communications team, the initiative demonstrates how a carefully curated campaign can be transformed into a multi-layered outreach success. From conceptualization to realization, the team worked closely with the eLTER Coordination and Head Office to create what is now known as the eLTER Grand Campaign—a journey across Europe to visually document the human and ecological stories behind the research stations.

The eLTER photo exhibition was displayed at the ‘Lover’s bridge’ in Sofia, Bulgaria.

Over the course of three months, photographer Evgeni Dimitrov and his team traveled across 23 European countries, visiting some of the continent’s most advanced long-term ecosystem research sites. Using both drone and handheld cameras, the team captured nearly 3,000 photographs and 50 videos, bringing an artistic lens to the world of environmental science. The visual materials created during the Grand Campaign will be integrated into the eLTER database, becoming a valuable resource for researchers and stakeholders across Europe. These assets will support ongoing efforts in data visualisation, educational outreach, and long-term documentation of ecosystem changes.

“During the trip, it was fascinating to observe the work of scientists—each team reflecting the specific national context, yet united by a shared goal: to collect increasingly detailed data that can help us create a better environment.

I aimed to portray the research stations not only from a technical perspective—showing the equipment and how it’s used—but also within the broader environment: the nature around them, the living beings they interact with, and the people behind the machines who bring meaning to otherwise dry data.

explained photographer Evgeni Dimitrov.

Seizing the momentum of the exhibition’s launch in Sofia, the Pensoft team also engaged with local media to broaden public awareness of the eLTER project. For example, the Bulgarian Telegraph Agency published a feature story, titled “Photo Exhibition Presents Research Stations across Europe in Sofia” in both Bulgarian and English, which highlights the exhibition, as well as the mission and goals of eLTER, with a special focus on the work of LTER-Bulgaria. Other local media also covered the news and promoting eLTER.

This strategic blend of visual storytelling, media engagement, and public outreach exemplifies Pensoft’s holistic approach to science communication.

From centrally managing a campaign, coordinating international logistics, and delivering high-quality media assets, to generating public interest and securing media coverage, this initiative shows how communication can become a vital extension of research impact.

This June, the eLTER project will be holding its very first science conference with the aim to bring together scientists across disciplines who are striving to adopt a holistic approach to the understanding of the complex interactions between living organisms, humans, and their physical environment in the critical zone.

The event will take place on 23-27 June 2025 in Tampere, Finland. Abstracts submitted to the conference will be made permanently available in the eLTER Science Conference abstracts collection in the journal-like ARPHA Conference Abstract platform.

Pensoft is a project partner and a work package leader in the eLTER projects. eLTER receives funding from the European Union’s Horizon 2020 research and innovation programme under GA No 871126 (eLTER PPP) and GA No 871128 (eLTER PLUS), and the European Union’s Horizon Europe research and innovation programme under GA No 101131751 (eLTER EnRich).

Eight years of ruin: the legacy of the Mariana dam disaster

Researchers explore the ongoing devastation caused by Brazil’s worst environmental disaster.

Eight years since the collapse of the Fundão tailings dam in Mariana, Brazil, researchers have highlighted ongoing environmental and social devastation caused by the disaster.

A paper published in our open-access journal Nature Conservation underscores the persistent and growing impacts of the collapse, which ranks as one of the world’s most significant environmental tragedies.

Caused by the Samarco mining company, the 2015 collapse released approximately 50 million cubic meters of toxic mud, burying the village of Bento Rodrigues and severely contaminating over 600 kilometres of river channels and coastal habitats. More than 1 million people across 35 cities were affected, leading to 19 deaths, widespread health issues, and the displacement of hundreds of residents.

According to researchers, the environmental damage has only intensified over the years. High levels of heavy metals continue to threaten human and wildlife health, with significant bioaccumulation observed in endangered species like the Franciscana dolphin. Additionally, the disaster caused the introduction of numerous invasive species, further destabilising the ecosystem.

The paper, led by Dr Cássio Cardoso Pereira and Fernando Goulart of Universidade Federal de Minas Gerais, criticises the slow and controversial response by the Renova Foundation, an entity created by the responsible companies to address the disaster’s aftermath. While some compensation and restoration efforts have been made, the researchers argue that these actions are insufficient and often inadequate.

One of the most concerning findings, they say, is the ongoing risk posed by similar structures across Brazil, where hundreds of dams remain in poor condition. The study advocates for the replacement of these dangerous dams with safer alternatives like dry mining, which significantly reduces the risk of future collapses.

“Urgent, science-based public policies are needed that prioritise the restoration of the Rio Doce basin, in addition to comprehensive compensation for affected communities. To achieve this, we need collaborations involving local and government oversight and independent scientific expertise to prevent further ecological and human disasters.”

As the region continues to face the compounded effects of climate change, with increasing cyclones and heavy rains worsening the spread of pollutants, the paper reminds us that the legacy of the Fundão disaster is far from over.

Integration of ecosystem services in urban planning tools can directly contribute to the sustainability of ecosystems

Integrated ecosystem services can be a potent tool to inform and guide spatial decision-making.

Guest blog post by Zeynep Türkay

Ecosystem services’ (ES) integration into global policies is widely recognized as a hope for environmental sustainability, as they provide a robust framework for representing natural values. The role of healthy ecosystems in combating climate change-related risks and ensuring the sustainability of ecosystem services that are critical for human-natural life is well understood, and in this context, the protection and sustainability of Integrated ES areas, which represent the highest ecological functional areas in this sense, need to be highlighted. Integrated ES can be a potent tool to inform and guide spatial decision-making. However, presently, there is a need to improve the content of related conventional tools on how to introduce and involve their roles in decision-making processes.

Our paper, published in the journal One Ecosystem, investigates the incorporation of this problem, underlines ES significance as the Integrated ES, and transfers this information into spatial decision-making. The content of the paper discusses the potential contributions and limitations of the integration. It provides solid suggestions on how Integrated ES can be operationalized in Istanbul’s high-level plans.

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.

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.

Flooded cities: A flood-regulating ecosystem services assessment for heavy rainfalls in urban areas

Scientists from Germany developed a framework with indicator suggestions to quantify and compare flood-regulating ecosystem services supply and demand.

Extreme weather events – like heavy rainfall – are a major environmental risk. Only recently after the Ecosystem Services Partnership (ESP) 2022 Europe Conference on Crete (Greece) some conference attendees were able to directly experience the effects of heavy rainfall, when air traffic was stopped in Heraklion for many hours, streets were flooded, properties damaged, and even people died.

Heavy rainfall can occur anywhere and are usually highly localized. Cities are particularly vulnerable to pluvial flooding because of the high degree of surface sealing, the high population density and the high potential of socio-economic damage in urban areas. In this light, ecosystems are important natural flood-regulating elements that can relieve grey infrastructure such as sewer systems. They can buffer rain events and prevent flooding as their functions turn into a flood-regulating ecosystem service (ES) to protect society.

So far, flood-regulating ES supply and demand for heavy rainfall in urban areas have rarely been studied. Therefore, scientists from the Climate Service Center Germany and the Leibniz University Hannover (Germany) developed a framework with indicator suggestions to quantify and compare flood-regulating ES supply and demand. Interception by canopies and infiltration in the soil serve as essential indicators for urban flood-regulating ES supply. The indicators can be quantified based on the outputs of a hydrological model that has explicitly been developed for this study. The model is based on single, individual landscape elements. It considers vegetation-hydrological interaction, and 2D surface water routing. Social-economic indicators and the surface flooding indicate the related ES demand.

In their study, published in the journal One Ecosystem, they assessed the flood-regulating ES of an urban district in the City of Rostock (Germany) for a one-hour heavy rainfall event. They found the highest mean ES supply on greened areas of forests, woodlands and green areas, resulting in a supply surplus. Whereas, sealed areas (paved surface where water cannot infiltrate into the soil), such as settlements, urban dense areas, traffic areas and industry, showed an unmet demand resulting from both low supply and relatively high actual demand. The results indicated that vegetation plays an important part in flood regulation, if the soils are saturated or sealed and, thus, should be considered in urban flood-regulating ES assessments.

Budget of the flood-regulating ecosystem services supply and demand resulting in unmet demand and supply surplus.

Analysing the supply and demand for flood-regulating ES is particularly important for urban planning in order to identify ES supply-demand mismatches. Based on this information, adaptation measures such as Nature-based Solutions can be planned and their possible ES contributions can be quantified. Since heavy precipitation events are projected to become more frequent and intense in the future, the future functionality of current flood-regulating ES and the benefits of adaptation measures under changing climate conditions need to be assessed. This provides information about changing ES supply and the development of ES demand.

First discovery of microplastics from water trapped on plant leaves

“These phytotelmata are very small and have a short lifespan. The question is, therefore, how were they polluted with microplastics?”

Although they have not been around for long, microplastics have found their way to almost every ecosystem on the planet. They have been discovered in the soil, in rivers, in our food and bottled water, and even in the human body. Recently, a team of researchers found, for the first time, microplastics in water trapped in plant leaf axils.

The teasel Dipsacus.

Katarína Fogašová, Peter Manko, and Jozef Obona of the University of Prešov, Slovakia, initially set out to Eastern Slovakia to study the organisms living in the little water puddles forming in teasel leaf axils. 

Teasels of the genus Dipsacus have characteristic opposite leaves that grow on the stem above each other in several levels. As they clasp the stem, they form cup-like structures that collect water, known as telmata. 

“Teasel phytotelmata are a relatively common but overlooked aquatic microcosm with a very short-term occurrence of only 3 to 4 months.“

To their surprise, they found differently coloured fragments and fibers, some reaching 2.4 mm in length, which were identified as microplastics.

“These phytotelmata are very small and have a short lifespan,” the researchers write in their paper, which was published in the journal BioRisk. “The question is, therefore, how were they polluted with microplastics?”

Phytotelmata provided by teasel.

No other sources of contaminants were found in the studied area, so the fragments and fibers most likely came from polluted atmosphere, they suggest. Another theory is that snails may have transported them from the soil or from other plants, in or on their bodies. 

“The first finding of microplastics in small short-term water reservoirs created by plants is further evidence that contamination of this kind spreads through various pathways and probably no environment on Earth is safe, which of course makes our discovery quite disheartening,” the researchers say.

“On the other hand, the results of our research of teasel phytotelmata, as a very unusual and highly specific natural environment, offer many possibilities for use in researching the spatio-temporal characteristics of the spread of microplastic pollution and its potential impact on the plants themselves, as well as organisms bound to them by ecological relations.”

They suggest that, due to their abundance and theoretical ability to capture microplastics in several ways from the environment, teasel phytotelmata could be a good indicator of microplastic presence.

“Our publication therefore not only brings the first discovery of microplastic pollution of habitats of this type, but also the first proposal of a new approach to the use of teasel phytotelmata and similar micro-ecosystems provided by plants (or artificially created), as bioindicators of the presence of microplastics in the environment, possible sources and pathways of their spread through the environment and spatio-temporal changes in microplastic contamination.”

Novel research seeks to solve environmental challenges in BioRisk’s latest issue

The special issue features 35 studies presented at the International Seminar of Ecology 2021

Guest blog post by Prof. Stephka Chankova, PhD

The new special issue of BioRisk compiles materials presented at the International Seminar of Ecology – 2021. The multidisciplinary nature of modern ecology was demonstrated by the main topics of the Seminar: biodiversity and conservation biology, biotic and abiotic impact on the living nature, ecological risk and bioremediation, ecosystem research and services, landscape ecology, and ecological agriculture.

Research teams from various universities, institutes, organizations, and departments, both from Bulgaria and abroad, took part in the Seminar. Foreign participants included: Environmental Toxicology Research Unit (Egypt), Pesticide Chemistry Department, National Research Centre (Giza, Egypt); National Institute for Agrarian and Veterinary Research (Oeiras, Portugal), Centre for Ecology, Evolution and Environmental Changes (Lisbon, Portugal); Bach Institute of Biochemistry, Research Center of Biotechnology of the Russian Academy of Sciences (Moscow, Russia).

Biorisk’s latest issue: Current trends of ecology

Some of the reports presented joint research of Bulgarian scientists and scientists from Germany, the Czech Republic, Lithuania, Romania, Slovenia, Spain, and the USA. After assessment by independent reviewers, the articles published in the journal cover the topics presented and discussed at the Seminar. 

A set of reports were focused on the anthropogenic and environmental impacts on the biota. Soil properties were shown as a factor that can modulate the effect of heavy metals, present in chronically contaminated soils. Different ap­proaches to overcome environmental pollution were presented and discussed: zeolites as detoxifying tools, microalgae for the treatment of contaminated water bodies, and a newly developed bio-fertilizer, based on activated sludge combined with a bacte­rial strain with detoxifying and plant growth-promoting properties. The clear need for the enlargement of existing monitoring program by including more bioindicators and markers was pointed out.

It was shown that, by using various markers for the evaluation of environmentally induced stress response at different levels (microbiological, molecular, biochemical), it is possible to gain insights of the organisms’ protection and the mechanisms involved in resistance formation. The contribution of increased DNA repair capacity and AOS to the development of environmental tolerance or adaptation was also shown.

Important results for understanding the processes of photoprotection in either cyanobacteria or algae, and higher plants were obtained by in vitro reconstitution of complexes of stress HliA protein with pigments. The crucial role of the cellular physiological state, as a critical factor in determining the resistance to environmental stress with Q cells was demonstrated.

Several papers were focused on the action of bioactive substances of plants origin. The bioactivity was shown to depend strongly on chemical composition. Origanum vulgare hirtum essential oil was promoted as a promising candidate for the purposes of “green” technologies. Analyzing secondary metabolites of plants, it was shown that their productivity in vitro is a dynamic process closely related to the plant growth and development, and is in close relation with the interactions of the plant with the environment.

The influence of the agricultural system type on essential oil production and antioxidant activity of industrially-cultivated Rosa damascena in the Rose valley (Bulgaria) was reported, comparing organic vs conventional farming. The rose extracts from organic farming were shown to accumulate more phenolic compounds, corresponding to the higher antioxidant potential of organic roses.

A comparative study, based on official data from the statistics office of the EU and the Member countries, concerning viral infection levels in intensive and organic poultry farming, demonstrated that free-range production had a higher incidence of viral diseases with a high zoonotical potential.

Pollinators of Lavandula angustifolia, as an important factor for optimal production of lavender essential oil, were analyzed. It was concluded that, although lavender growers tend to place beehives in the fields for optimal essential oil production, it was crucial to preserve wild pollinators, as well.

Lavandula angustifolia inflorescence excluded from pollinators.

New data reported that essential oils and alkaloid-rich plant extracts had the strongest acetylcholinesterase inhibitory activity and could be proposed for further testing for insect control.

It was reported that the vegetation diversity of Bulgaria had still not been fully investigated. Grasslands, broad-leaved forests, and wetlands are the best investigated habitats, while data concerning ruderal, shrubland, fringe, and chasmophytic vegetation in Bulgaria are scarce.

Other important topics were reported and discussed in this session: the possibility of pest control using pteromalids as natural enemies of pests in various crops; the main reasons responsible for the population decrease of bumblebees – habitat destruction, loss of floral resources, emerging diseases, and increased use of pesticides (particularly neonicotinoids); the strong impact of temperature and wind on the distribution of zooplankton complexes in Mandra Reservoir, in Southeastern Bulgaria; an alternative approach for the ex-situ conservation of Stachys thracica based on in vitro shoot culture and its subsequent adaptation under ex vitro conditions.

New information was presented concerning pre-monitoring geochemical research of river sediments in the area of Ada Tepe gold mining site (Eastern Rhodopes). The obtained results illustrate that the explored landscapes have been influenced by natural geochemical anomalies, as well as, impacted by human activity. The forests habitat diversity of Breznik Municipality was revealed, following the EUNIS Classification and initial data from the Ministry of Environment and Water and the Forestry Management Plans. It was shown that, in addition to the dominant species Quercus dalechampii, Quercus frainetto, Fagus sylvatica, Carpinus betulus, some artificial plantations with Pinus nigra and Pinus sylvestris were also present, as well as non-native species, such as Robinia pseudoacacia and Quercus rubra.

Models for Predicting Solution Properties and Solid-Liquid Equilibrium in Cesium Binary and Mixed Systems were created. The results are of great importance for the development of strategies and programs for nuclear waste geochemical storage. In conclusion, many results in different areas of ecology were presented in the Seminar, followed by interesting discussions. A lot of questions were answered, however many others remained open. A good platform for further discussion will be the next International Seminar of Ecology – 2022, entitled Actual Problems of Ecology.

One Ecosystem calls for papers that report ecosystem accounts

To help implement ecosystem accounts, the One Ecosystem journal provides a platform for scientists and statisticians to publish newly compiled accounting tables.

In March 2021, the UN Statistical Commission adopted the System of Environmental-Economic Accounting Ecosystem Accounting (SEEA EA).

SEEA EA is a spatially-based, integrated statistical framework for organising biophysical information about ecosystems, measuring ecosystem services, tracking changes in ecosystem extent and condition, valuing ecosystem services and assets and linking this information to measures of economic and human activity. 

To help implement ecosystem accounts, the One Ecosystem journal provides a platform for scientists and statisticians to publish newly compiled accounting tables. 

The “Ecosystem Accounts” permanent collection welcomes articles that describe and report ecosystem accounting tables, compiled following the standards set by the SEEA EA. The current version of the framework is fully described in United Nations et al. (2021). System of Environmental-Economic Accounting—Ecosystem Accounting (SEEA EA), available as a white cover publication, pre-edited text subject to official editing at: https://seea.un.org/ecosystem-accounting.

This collection does not accept research papers on ecosystem accounting that solely report new developments on accounting methods, such as new models for ecosystem services, new indicators for ecosystem condition or new techniques for monetary valuation of ecosystems. 

The inclusion of a compiled ecosystem accounting table is mandatory for this collection. Otherwise, papers will be diverted to the regular issue of One Ecosystem. In such cases, the authors may also choose to submit their contributions to another topical collection.

  • This section describes which typologies or classifications have been used to classify ecosystems, ecosystem condition indicators, ecosystem services, or economic sectors. Preference should be given to different typologies proposed by SEEA EA, but deviations or other typologies are acceptable as well. 
  • The section provides a list of all ecosystem types, variables, indicators, or economic sectors used in the accounting tables and it provides references to the data sources used to quantify them. 
  • Optionally, papers justify the use of variables and indicators making reference to specific selection criteria. 
  • For ecosystem service accounts, this section describes or refers to the methods used to quantify ecosystem services.
  • For monetary accounts, this section describes or refers to the methods used to assign monetary values to ecosystem services.
  • The use of supplementary materials is recommended in case the description of data and methods is too long. In that case, this section contains a summary of the data and methods. 

Accounting tables and results

  • This section presents the accounting table(s). Ideally, this section presents the most aggregated version of the accounting table(s), while detailed versions with a high number of rows and columns can be easily published as a spreadsheet in the supplement section of the paper.
  • Stylised versions of accounting tables are available in the SEEA EA guidelines. A stylized example for each ecosystem accounting table is available in MS Excel. It is highly recommended to follow these examples to the maximum possible extent. 
  • Graphs or maps that illustrate the accounting tables or that provide key results used to compile the accounting table can be published as well in this section. 

Discussion 

In this section, authors are invited to add at least one of the following topics:

  • A short interpretation of the results: are the reported data comparable to other published data on ecosystem extent, condition or services or do they deviate substantially. 
  • Critique or comments on the SEEA EA framework. Identify issues with application of the framework. Highlight areas for improvement or further research.
  • Demonstration of how the accounts have been or can be used to support policy and decision making or implementation. Particular cases of interest are (however, not restricted to) agricultural, forestry, fishery and biodiversity policies, biodiversity and ecosystem monitoring and reporting, ecosystem restoration projects, demonstrating values of ecosystems, or environmental impact assessments.

Green backyards help increase urban climate resilience: Here is how

New study evaluates the effects of greenery on thermal comfort, biodiversity, carbon storage and social interactions.

Green spaces in cities have a number of positive effects: they’re good for our physical and mental health, they’re good for the environment, and they can even help fight off the effects of climate change.

To explore the impact of additional green structures in cities, Katja Schmidt and Ariane Walz, affiliated with the University of Potsdam, Germany, quantified their effects on different aspects such as thermal comfort, biodiversity, carbon storage and social interaction. Their study, published in the open-access, peer-reviewed journal One Ecosystem, combines knowledge from health research, ecology and socio-ecological research, and shows how the better we know a particular type of ecosystem, the better we can adapt to climate change.

Pursuing a multi-method approach that ranged from local climate measurements to habitat and tree mapping, the authors compared four green residential courtyards in Potsdam. The spaces were similarly built, but had different ratios and sizes of features (lawns, flowerbeds, paths, playgrounds and allotments), as well as different tree and shrub population. 

While doing their research, Schmidt and Walz saw how even small differences in the green structure affect the provision of benefits, but one thing was clear: the greener courtyards yielded more benefits. Trees have the vital ability to cool down the environment and increase thermal comfort. Remarkably, the researchers report additional cooling effects of up to 11°C in the greener court yards. This means that residential green structures can prove of great value for human health during summertime heat, when asphalt and buildings make hot days even hotter. Considering the ageing demographic and the likely increase of heatwaves in the area, this is likely to have even greater health implications in the coming years.

Urban green spaces can also be an important factor in carbon storage, as urban soils and trees have the capacity to act as a sink for atmospheric carbon dioxide. The residential yards with more and larger trees, logically, have the power to store more carbon. This is where proper maintenance comes in: when yards are managed sustainably, trees live longer and can store more carbon.

“Considering the trend of increasing quantity and magnitude of extreme weather events and the vulnerability of urban areas, green spaces are known to provide great potential to increase urban climate resilience. Our work highlights the widespread positive effects of additional green structures in residential open spaces, a type of urban green space that is frequently understudied,” points out Dr. Schmidt.

As a conclusion, the researchers point out that if land owners and leaseholders receive incentives to commit to climate adaptation, and neighbourhoods come up with deliberate management strategies, these benefits could be further enhanced, contributing to a more sustainable urban development.
