Researchers propose a more effective method to predict floods

A team of researchers from Xi'an Jiaotong-Liverpool University and other institutions has identified a flexible and user-friendly model for predicting flood frequency in a changing environment. The fractional polynomial-based regression method is more effective than existing models, which often fail to account for factors like climate ...

Less intensively managed grasslands have higher plant diversity and better soil health, research shows for first time

Researchers found that less intensively managed grasslands had greater diversity of plant species and correlated with better soil health, including increased nitrogen and carbon levels. In contrast, intensively farmed plots showed fewer plant species, but some saw improvements in soil health over time.

Gully erosion prediction tools can lead to better land management

Researchers developed a modeling framework using remote sensing data to predict gully erosion susceptibility. They found that spatiotemporal changes in land cover and precipitation were crucial in predicting gully formation in agricultural areas, with 7.4% of the study area having an elevated risk of developing gullies.

Half of replanted tropical trees don’t survive, new study finds

A recent study found that on average, about half of trees planted in tropical and sub-tropical forest restoration efforts do not survive more than five years. However, survival rates varied greatly amongst sites and species, with some sites seeing over 80% of trees still alive after five years.

Has a beautiful songbird become an invasive species in Britain?

A new study finds the Red-billed Leiothrix, a small songbird native to subtropical Asia, has become an invasive non-native species in Britain. The species' potential impact on local wildlife and ecosystems is being highlighted by researchers, who note that it could cause significant changes if widely established.

​​​​​​​Vocal non-native songbird could change Britain’s dawn chorus as we know it

A new study warns that the Red-billed Leiothrix, a loud and brightly coloured bird from subtropical Asia, could become established in Britain, altering the country's dawn chorus. The species has already been spotted in several parts of Europe and is kept as a cage bird, potentially leading to its escape into the wild.

Seasonal variations of methane (CH4) consuming and methane producing microbial communities contribute to CH4 emissions in wetlands

Researchers investigated the impact of seasonal variations in methanogenic and methanotrophic communities on CH4 emissions in wetlands. They identified a keystone species that plays a pivotal role in mediating CH4 fluxes, providing substantial evidence for understanding microbial driving mechanisms.

Climate change affects landscape freeze-thaw but not in the same way everywhere, a new Concordia study shows

A new Concordia study reveals that climate change affects the province-wide analysis of landscape freeze-thaw cycles, leading to increased greenhouse gas emissions in northern regions and transitional days in southern areas. This can have significant impacts on infrastructure and greenhouse gas emissions.

New study aims at calculating terrestrial carbon’s role in river and stream emissions

A new Yale University-led study calculates the amount of terrestrial carbon emitted into streams and rivers, highlighting the importance of hydrology. The research reveals that monthly emissions fluxes vary more in Arctic and northern temperate rivers than in tropical and southern temperate rivers.

Swiss rivers on track to overheat by the end of the century

According to a new EPFL study, Swiss rivers are at risk of overheating by the end of the century. If greenhouse gas emissions are reduced, river temperatures may only rise by 1°C and discharge decreases by 5% in mountain catchments. Inaction could lead to extreme consequences, including glacier loss and decreased biodiversity.

Beetles in Climate Change

A study found that beetles in German forests shifted their diversity to Red-Ash trees when European Ash trees died due to drought stress. This suggests that non-native trees can provide opportunities for insects during times of climate change.

Water as a precious commodity: Competition for natural resources prevents sustainable development and excludes entire communities from water resources

A study by Politecnico di Milano reveals that large-scale land acquisitions for agriculture lead to increased water scarcity, impacting local users. The research analyzed 160 acquisitions and found that 105 resulted in competition for water, often at the expense of local communities.

Air pollution significantly reduces pollination by confusing butterflies and bees

Common air pollutants from urban and rural environments reduce pollinating abilities of insects, leading to fewer flower visits and overall pollination reductions. The study observed up to 70% fewer pollinators, 90% fewer flower visits, and a 31% reduction in pollination when common ground-level air pollutants were present.
