(Press-News.org) Villages, often separated from larger towns and cities, consist of clusters of households and a few public buildings. Despite their long history, the biodiversity of European villages has been understudied compared to urban areas, forests, grasslands, or agricultural fields. A new study reveals their biodiversity potential and how nearby landscapes influence biodiversity patterns and human well-being.
This research was led by an international team from the HUN-REN Centre for Ecological Research with 20 other institutes contributing from Hungary, Romania, Germany, and Italy. Published in Nature Sustainability, the study examines how landscape complexity and proximity to cities affect village biodiversity and socioeconomic conditions. The findings show higher biodiversity in villages within forest-dominated landscapes compared to agricultural settings, while city proximity boosts human well-being.
The researchers surveyed biodiversity in 64 villages around 16 mid-size cities in Hungary and Romania. Half of the villages were near cities, the other half farther away, and were either in agriculture- or forest-dominated landscapes. The team conducted botanical surveys, used pitfall traps for ground-dwelling arthropods, employed D-vac suction sampling for vegetation-dwelling arthropods, and set trap nests for cavity-nesting bees and wasps, as well as point counts for birds.
They documented 1,164 species across nine taxonomic groups. Multitrophic diversity, a measure of overall biodiversity, was 15% lower in villages surrounded by agricultural fields than by forests. Lead author Dr. Péter Batáry explains, “This underscores the importance of landscape-wide species pools in shaping village biodiversity. City proximity had little impact on species numbers and overall diversity, suggesting other factors have a greater influence.”
The team also collected socioeconomic data for Hungarian villages to calculate the Better Life Index, reflecting human well-being through living conditions and quality of life. The Better Life Index was 27% higher in villages in the agglomerations of cities and 14% higher in villages in forest-dominated landscapes than those in agricultural ones. Co-author Dr. Katalin Szitár notes, “Proximity to urban areas brings better access to services, while forested landscapes offer cleaner air and more green spaces, enhancing living standards and quality of life.”
Using GIS, the researchers measured the Human Footprint Index (HFI) to assess environmental impact from infrastructure and land use. Villages with a higher Better Life Index also had a higher HFI, especially near cities, indicating that better living standards can increase environmental impacts. A higher HFI was linked to lower multitrophic diversity, revealing a trade-off between human development and biodiversity. However, forest-dominated landscapes maintained higher biodiversity despite increased human activity, suggesting complex landscapes can mitigate biodiversity loss. Dr. Edina Török notes, “Our findings highlight the delicate balance needed to enhance human well-being without compromising the ecological health of rural landscapes.”
To be effective, sustainable village management should integrate landscape context into development plans. For villages near cities, minimizing soil sealing and green infrastructure intensification can help protect biodiversity. In villages predominantly surrounded by forests, limiting agricultural expansion is crucial. Increasing the connectivity of villages centres with forests and upgrading green infrastructure in agricultural areas can boost biodiversity and well-being. Collaboration between residents, authorities, and landowners, combining policy-driven and community-driven actions, is vital. Dr. Péter Batáry emphasizes, “The EU Rural Development Strategy should prioritize biodiversity management to improve conservation and landscape quality in and around villages.”

Planned hydrogen refuelling stations may lead to millions of euros in yearly losses
2025-07-04
As hydrogen infrastructure is rolled out in the EU, refuelling stations must be distributed according to the same principle in all countries. But now a study from Chalmers University of Technology in Sweden points to shortcomings in EU regulations. Using an advanced model, the researchers show that the distribution of refuelling stations may both be incorrectly dimensioned and lead to losses of tens of millions of euros a year in some countries.
By 2030, EU countries must have built hydrogen refuelling stations at least every ...
Planned C-sections increase the risk of certain childhood cancers
2025-07-04
Children born by planned C-section have an increased risk of developing acute lymphoblastic leukaemia (ALL) later in life. This is shown by a study conducted by researchers at Karolinska Institutet. The researchers emphasise that the risk remains low.
The study, published in The International Journal of Cancer, covers nearly 2.5 million children born in Sweden during two periods, 1982 to 1989 and 1999 to 2015. Of these, 15.5 per cent were born by C-section, i.e. nearly 376,000 children. In the entire group, 1,495 children later developed leukaemia.
Using the Medical Birth Register, the ...
Adults who have survived childhood cancer are at increased risk of severe COVID-19
2025-07-04
People who have survived cancer as children are at higher risk of developing severe COVID-19, even decades after their diagnosis. This is shown by a new study from Karolinska Institutet published in the journal The Lancet Regional Health – Europe.
Thanks to medical advances, more and more children are surviving cancer. However, even long after treatment has ended, health risks may remain. In a new registry study, researchers investigated how adult childhood cancer survivors in Sweden and Denmark were affected by the COVID-19 pandemic.

New genetic finding uncovers hidden cause of arsenic resistance in acute promyelocytic leukemia
2025-07-04
Researchers at Zhejiang University School of Medicine have identified a single point mutation in the normal PML gene that can block the effect of arsenic trioxide, a frontline drug for acute promyelocytic leukemia. This discovery uncovers a hidden cause of treatment failure and suggests a new target for genetic screening in relapsed patients. This work addresses the urgent issue of why some patients relapse despite a therapy that otherwise greatly improves survival.
Mutation Explains Why a Small Portion of Leukemia Patients Relapse on Arsenic Therapy
Arsenic trioxide cures most acute promyelocytic leukemia patients, but some patients relapse without an ...
Native habitats hold the key to the much-loved smashed avocado’s future
2025-07-04
The future of smashed avocado might depend on patches of native vegetation preserved alongside farmland, as new Curtin research reveals the hidden role of these habitats in supporting the insects that keep crops - and brunch menus - thriving.
The research, published this week, found that insect communities in avocado orchards adjacent to native remnant vegetation foraged on more than twice as many plant species at times when crop flowering was limited, compared to those in orchards bordered by pasture.
Insects with more diverse food sources are more likely to survive and pollinate crops so this finding offers a potential clue to safeguarding ...
Using lightning to make ammonia out of thin air
2025-07-04
University of Sydney researchers have harnessed human-made lightning to develop a more efficient method of generating ammonia – one of the world’s most important chemicals. Ammonia is also the main ingredient of fertilisers that account for almost half of all global food production.
The team have successfully developed a more straightforward method to produce ammonia (NH3) in gas form. Previous efforts by other laboratories produced ammonia in a solution (ammonium, NH4+), which requires more energy and processes to transform it into the final gas product.
The current method to generate ammonia, the Haber-Bosch process, comes at great ...
Machine learning potential-driven insights into pH-dependent CO₂ reduction
2025-07-04
Some of the most encouraging results for reaction-enhancing catalysts come from one material in particular: tin (Sn). While Sn's overall utility as a catalyst is well-known, its underlying structure-performance relationship is poorly understood, which limits our ability to maximize its potential. To address this knowledge gap, researchers at Tohoku University's Advanced Institute for Materials Research (WPI-AIMR) used machine learning to characterize Sn catalyst activity. The highly accurate simulations could be a game-changer that helps researchers swiftly and simply ...
Physician associates provide safe care for diagnosed patients when directly supervised by a doctor
2025-07-03
Physician associates provide safe and effective care when they work under the direct supervision of doctors and care for patients who have already been diagnosed, or when they undertake procedures for which they have been highly trained, finds a rapid review published in The BMJ today.
However, the rapid review on the safety and effectiveness of physician associates found insufficient evidence to support them assessing undiagnosed patients under indirect supervision—when seeing undiagnosed patients in primary care, for example.
Patient satisfaction levels ...
