Up-to date scientific and technological research is vital to allow humans to adapt appropriately to our changing global environment, and current rates of environmental degradation and resource depletion. Effective research policies are essential to maintain or improve the standard of life for future populations – in Europe and globally.

Grasslands cover 30–40% of European agricultural areas. Agri-environmental schemes leading to even small changes in grassland biodiversity could elicit extensive benefits. A new study on working farms in southwest England highlights the contribution of the plant diversity of the grassland to the abundance and diversity of insect pollinators and their potential to increase crop yields. The researchers make recommendations for which species to include in seed mixes.

Assessing threats to biodiversity is necessary for effective spatial planning and balancing sustainable development with conservation. This study details a fine-scale assessment of the effect of a range of threats to coastline habitats within a Marine Protected Area (MPA) in the Mediterranean Sea. The study provides an example of how local-scale assessments can contribute to national conservation policy.

Land-use changes in the arid south-eastern Iberian Peninsula impact on the supply of various ecosystem services that support human well-being. Research into perceptions of the rapid expansion of greenhouse horticulture and the abandonment of rural and mountainous areas has highlighted trade-offs between conservation efforts and economic development.

Eradication of invasive mammal species is a strategy used to help conserve biodiversity on islands and restore populations of native species. Researchers have now assessed the success of this strategy globally, highlighting the importance of controlling invasive species to protect biodiversity on islands and achieve global conservation targets.

Biodiversity scenarios are a useful tool to help policymakers predict how flora and fauna will likely respond to future environmental conditions. Although changes to land use are a major driver of biodiversity loss, scenarios focus overwhelmingly on climate change, a new study shows. The researchers say this imbalance makes scenarios less credible, and make recommendations for developing more plausible projections.

A new approach to modelling the spread of mammal populations under climate change has been developed. The method overcomes the problem of missing ecological data for most species by using information on species characteristics, or ‘traits’, associated with population demographic rates and individual movements to deduce which species move too slowly to escape climate change’s effects on their habitat. The model’s results suggest that around 30% of mammal species may not be able to disperse quickly enough to survive.

Scientists have developed a new way of monitoring Ponto-Caspian gobies, a group of widely invasive fish species, by detecting traces of the fishes’ DNA in river water. They say, in a recent research paper, that it offers a quicker, easier and cheaper way of monitoring the fish than conventional catching or sighting methods.

A new long-term monitoring study is the first to demonstrate that climate changes are having divergent effects on populations of bird species across Europe and the United States. The study identifies broad-scale impacts on the abundance of common bird species over a 30-year period, to show that, overall, populations of bird species across both continents are being affected by changes in climate. The research adds to a growing body of evidence that climate change is affecting biodiversity either positively or adversely, depending on species’ climate preferences.

The risk of alien species introduction via trade in plants is higher if the plants are from poorly regulated countries with high forest cover, calculates a recent study. For introductions via the vehicle and timber trades, the risk is higher if the exporting country is politically unstable. These findings could help border controls focus their surveillance efforts on imports from countries with risky socioeconomic profiles.

A new study has analysed marine litter on beaches across the UK, indicating that the fishing industry is responsible for large quantities of marine rubbish. The researchers recommend a combination of better enforcement of regulations covering waste disposal, and incentives for fishing vessels to reduce marine litter.

Sustainable drainage systems (SuDS) could be made better for biodiversity and local people with the help of two new evaluation methods presented by a recent study. The methods, which assess the value of SuDS sites for wildlife habitat, carbon sequestration, recreation and education, are described by the study’s authors as cost-effective, quick and reliable, and could help designers plan and retrofit SuDS that are wildlife-friendly and socially inclusive.

A UK solar park has been found to change the local microclimate, reports recently published research. Moreover, the microclimate coupled with management activities had an impact on greenhouse gas emissions and plant-community diversity and productivity under the solar panels. The study’s authors say their research provides a starting point for considering how to improve solar-park design in order to deliver co-benefits for biodiversity and farming, and minimise any negative environmental effects.

Transport infrastructure is so widespread in Europe that half of the land area is within 1.5 kilometres (km) of paved roads and railway lines, researchers have calculated. The researchers found that in Spain, transport infrastructure has an impact on the abundance of birds in almost half of the country and is affecting the abundance of mammals across almost all of the land area.

The coverage of ‘Important Bird and Biodiversity Areas’ (IBAs) in relation to Special Protection Areas (SPAs) for birds in the EU has been assessed in a new study. Overall, 66% of the IBA network is covered by SPAs. SPAs were found to cover 23% of the distributions of 435 EU bird species as well as 25% of the distributions of mammals, reptiles and amphibians.

This study is one of few to assess the genetic diversity of crops in an agroecosystem over several years. Researchers analysed the genetic makeup of oilseed rape plants within and outside crop fields over four years. They found similarity between cultivars of field plants in one year and those of feral plants (unplanted) in the following year. They also found persistence of the cultivars within the feral plants, which suggests that feral populations with genetically modified (GM) traits might result from persistent GM traits within field seed banks. The researchers say their findings could aid impact assessments of GM crops.

The black locust tree can be economically valuable and offer certain environmental benefits, but its dominant and invasive nature in Europe can have an adverse impact on biodiversity. A recent study, which presents an overview of this species’ ecological and socio-economic impacts in Central Europe, recommends tolerating the tree in some areas and eradicating it in others, in order to balance its co-existence with people and nature.

The influence of light-emitting diodes (LED) on grassland invertebrate communities has been assessed in a recent study. White LEDs increased the total abundance and changed the species of spiders and beetles recorded. Dimming lights and switching lights off during the middle of the night were the best ways of reducing the effects on beetle and spider numbers.

Agri-environment schemes (AES) have been implemented throughout Europe to mitigate against the negative effects of agricultural intensification. Although these schemes have shown positive effects on the abundance and richness of certain species and taxa, the impact of AES on reproduction of target species at the local and landscape scale is poorly understood. This large-scale study looked for the effect of selected AE measures on bumblebee reproduction. Results indicate that bumblebee reproduction is significantly higher on sown flower patches when compared to conventional management. Although the increase is most pronounced at the plot scale, higher reproduction was found in landscapes surrounding larger sown plots (at least one hectare) compared to smaller sown plots.

Habitat fragmentation is a threat to biodiversity, especially in agricultural land where there are also many endangered species. Corridors between habitats are one way to counteract its effects. A study suggests that grassy field margins — established throughout Europe to improve water quality — could act as corridors. The study, which measured the effects of field margins on butterflies, concludes that agricultural schemes should include this corridor function.

A new study has investigated the effects of set-aside management —when fields are taken out of agricultural production — on common invertebrate decomposers in soil. The diversity of woodlice species was higher in set-aside fields compared to neighbouring wheat fields and this effect increased in older set-asides. This study highlights the importance of set-aside areas as habitats for soil invertebrates, which are important for soil health.

This study assessed the implementation of the ‘Flowering Meadows’ agri-environment scheme in France, a results-based scheme which encourages farmers to conserve meadows in the Bauges, Haut Jura and Vercors natural parks. While there was limited change in agricultural practices, the scheme did help to maintain meadow habitats. Farmers also welcomed the results-based payments approach, which gave them greater responsibility for and flexibility in managing their farms.

Results-based agri-environment measures are an alternative to management-based measures that, in certain circumstances, could be both more effective and more cost-efficient, since their payment depends on the provision of the desired conservation outcome. This study reviews the success of a scheme, introduced in Germany in 2000, to preserve biodiversity in species-rich grassland.

Researchers have developed a new metric to predict the ecological impacts of invasive alien species. The metric was calculated for a number of known invasive alien species and successfully predicted their impact on native species. The tool could be used to help inform the global management of invasive alien species.

A new study suggests that Earth’s ongoing mass extinction episode is more severe than generally perceived. Rather than focusing on the complete extinction of entire species, researchers analysed the losses and declines of populations in a sample of 27 600 vertebrate species. Population declines and losses are often a prelude to species extinctions. Researchers also conducted a more in-depth analysis of population losses between 1900–2015 in 177 mammal species. The results reveal that rates of population loss and decline in vertebrates are extremely high, even in common “species of low concern”. The data indicates that, in addition to significant species extinction rates, the Earth is experiencing a huge episode of population decline and loss, which will have a significant effect on ecosystem functioning and services. The researchers warn that the window for effective action is closing rapidly and emphasise the need for an urgent response.

Invasive alien species (IAS) pose a threat to native European biodiversity and cost the EU annual damages worth EUR 12 billion as a result of IAS effects on human health, damaged infrastructure, and agricultural losses. IAS are the focus of Target 9 of the Convention of Biological Diversity (CBD) and Target 5 of the EU Biodiversity Strategy: ‘By 2020, IAS and their pathways are identified and prioritised… pathways are managed to prevent the introduction and establishment of new IAS.’ The EU framework for action against IAS is set out in a Regulation adopted in 2014. This provides for the adoption of a list of IAS of Union concern that will be subject to restrictions across the EU. The first step in order to consider a species for listing is to undertake a risk assessment.

Energy demand is on the rise globally, and this is predicted to continue in coming decades. Increasing energy production to meet this demand requires materials — both metals and non-metal minerals — from a number of countries. As some materials are in short supply, it is important to consider material dependency and availability when developing national energy plans for the future. This study is the first to address material dependency effects on a nation’s energy development plans, with the UK and Turkey as case studies.

The warmer, drier conditions expected under on-going climate change will reduce the rates at which soil fauna and microbes decompose plant litter, suggests new research from Germany. This may have important implications for agriculture and natural ecosystems worldwide, as litter decomposition is a key process in cycling and distributing nutrients throughout ecosystems.

Considering the impact on soil carbon, biodiversity and ecotoxicity is important when assessing the environmental footprint of dairy products, suggests a new study, which explored the impacts of organic and conventional milk production in three types of system established in Western Europe. The study found that organic milk production had a significantly lower impact on ecotoxicity and biodiversity than conventional milk production, and suggests that including soil carbon changes in the assessment would result in greater reductions in the carbon footprint of organic, rather than conventional, milk — in some cases by up to 18%.

As the threat of novel corona virus COVID-19 spreads through the world, we live in an increasingly anxious time. While healthcare workers fight the virus in the front line, we do our part by practicing social distancing to slow the pandemic. Today's guest blogger, Toshi Takeuchi, would like to share how he spends his time by analyzing data in MATLAB.... read more >>

New research demonstrates how nanoparticles of silver in antibacterial socks and other fabrics may be released into the environment by washing. The study suggests that the release of silver from the textiles depends to a large extent on the way the silver has been incorporated into the fabric and that producers have possibilities for minimising release.

A comprehensive analysis of pharmaceuticals in Spanish wastewater has indicated that they are widespread pollutants. The majority of pharmaceuticals present in incoming wastewater were still present in both treated water and in the river waters receiving the treated water.

A new study has combined two research methods to assess the risk of pesticide contamination within a river basin and identify locations of risk. Six groups of pesticides were identified in a French river basin and one specific area was labelled as 'high risk' due to intense agriculture.

A new study from Austria shows that ozonation, a more advanced form of waste water treatment, may be required to further reduce levels of trace pollutants, called micropollutants, in addition to longer treatment times.

Researchers have developed the first biology-based model to predict the sub-lethal effects of chemical mixtures on organisms. Sub-lethal effects do not cause death but can damage processes such as growth and reproduction. The model provided accurate predictions of the sub-lethal impacts of a chemical mixture on water fleas.

Assessing the cumulative human health risk caused by multiple toxic substances is a major challenge. New research has reported on developments in the US, where the Environmental Protection Agency (EPA) is creating a tool that will provide maps and other information to depict exposure data and risks at both a national and a local level.

New research has supported a more thorough integration of toxic mixture assessments into two major pieces of EU legislation: REACH and the Water Framework Directive. It recommended constructing a database of harmful chemicals in the environment which, among other uses, could assess mixture toxicity using a 'Concentration Addition' method.

The United Nation's Globally Harmonised System of Classification and Labelling of Chemicals (GHS) is an international initiative to standardise how chemicals are managed across the world. A recent study has proposed a suite of indicators which measure progress in implementing the GHS.

A recent report calls for an urgent, worldwide ban on the mining and use of asbestos. It argues that there is no safe use of asbestos that can prevent occupational and environmental exposure and urges all countries to use safer alternatives to asbestos in order to protect the health of their citizens.

Governments and industry must act quickly to address the impacts of rapidly rising volumes of 'nanowaste', according to research. The study warns against continuing unabated release of nanomaterials into the environment and outlines a number of practical steps that should be taken in order to start dealing with the problem.

Light Emitting Diodes (LEDs) are an energy efficient and mercury-free source of lighting, but like other electronic goods they could have some negative environmental impacts, according to research. A US study tested a selection of LEDs and found that they could be classified as hazardous waste owing to levels of lead, copper, nickel and silver. Their use of rare earth metals could also increase pressure on natural resources.

In line with EU legislative requirements, new research has developed models to assess the toxicity of chemicals in terms of their effects on human development. One of the models has been made freely accessible online, so that it is easy to use for industry and regulators.

A new approach to assessing the risk posed by 500 organic chemicals potentially found in the surface waters of river basins across Europe has been developed. It allows pollutants of concern, including emerging substances, to be identified and prioritised by Member States for monitoring and action as required by the Water Framework Directive.

By ranking the ‘hazard potential’ of a wide range of chemicals used to make common plastics, Swedish researchers have highlighted which plastic polymers are made from the most hazardous chemicals. These should be prioritised for assessing the risk of causing human or environmental harm.

A recent study has considered the levels at which active pharmaceutical ingredient (API) residues are safe when released into water bodies from drug manufacturing plants. It proposes that environmental reference concentrations and maximum tolerable concentrations are adopted for each API.

Comparative toxic assessments across regions and countries are needed to minimise human exposure to harmful chemicals associated with consumer products. A new study has developed a US version of the EU Toxic Potential Indicator (TPI) and compared the two models for over 500 chemicals. Differences in results exist, indicating a need for more harmonisation between regulatory thresholds and guidelines.

Commercial bottom trawling, the technique of pulling fishing gear across the seabed to catch fish and other seafood, releases pollutants trapped in the seabed, which can negatively affect local marine life and ecosystems. Recent findings from a Norwegian fjord show how mussels can take up high levels of contaminants released by trawling, with important health implications for consumers.

The use of nanomaterials in consumer goods is growing, as is their presence in waste. A new study is the first to follow the fate of engineered nanoparticles through the entire waste incineration chain. The results indicate current filter technology is effective in removing nanoparticles from flue gas, but that nanoparticles also bind to residues, such as fly ash and slag, which eventually end up in landfill.

A new study has evaluated disinfection by-products (DBPs) formed during the treatment of ballast water. As some of the DBPs produced are hazardous, the study concludes that more information is needed to ensure DBPs from treatment methods do not harm human health or aquatic environments.
