Increasing overlap of fire weather between Australia and North America complicates international firefighting efforts Climate change is increasing the risk of wildfires in many regions of the world. This is due partly to specific weather conditions – known as fire weather – that facilitate the spread of wildfires. Researchers from the Helmholtz Centre for Environmental Research (UFZ) and Australian colleagues have found that fire weather seasons are increasingly overlapping between eastern Australia and western North America. The research team examined…
Thornless, disease-resistant, and tastier blackberries could be on the horizon — thanks to new genetic research from the University of Florida. New UF blackberry varieties could provide a boon for farmers looking to rebound after the decline of Florida citrus and who see an opportunity to meet the growing demand for blackberries, which have soared in popularity in recent years. “Overall, this study not only advances our understanding of blackberry genetics, but it sets the stage for significant improvements in…
Discovered genes provide strategies to protect rice crops against climate change and to domesticate wild relatives that can grow in currently unproductive habitats A new study, seen in Nature Genetics and led by researchers at King Abdullah University of Science and Technology (KAUST; Saudi Arabia) and Wageningen University & Research (the Netherlands), provides new insights on rice evolution, showing how the DNA of this valuable crop has changed across species. The findings are expected to not only help with improving…
Chinese scientists have discovered that fragile swamp forests in the Pearl River Delta (PRD) region suddenly collapsed around 2.1 thousand years ago (ka)—with human activity as the cause. The study, led by researchers from the Guangzhou Institute of Geochemistry and the Institute of Oceanology of the Chinese Academy of Sciences, sheds new light on the role of human activity in ecosystem collapse. Published in Science Advances, the study focuses on Glyptostrobus pensilis (G. pensilis), a critically endangered species of Chinese swamp cypress that once…
By analyzing DNA from different cells in nearly 200 lines of maize plants, research led by the University of Michigan has revealed insights that could help growers better adapt their crops to a fast-changing environment. The new study led by Alexandre Marand reveals previously hidden information about the activity of genes inside different cell types. This provides essential context that helps better understand how the molecular biology of a lineage connects to its readily visible traits, or its phenotype. This…
Farmers apply nitrogen fertilizers to crops to boost yields, feeding more people and livestock. But when there’s more fertilizer than the crop can take up, some of the excess can be converted into gaseous forms, including nitrous oxide, a greenhouse gas that traps nearly 300 times as much heat in the atmosphere as carbon dioxide. About 70% of human-caused nitrous oxide comes from agricultural soils, so it’s vital to find ways to curb those emissions. Before they can recommend practices…
In the largest study of its kind, researchers at the Florida Museum of Natural History have used data from a 120-year-old program managed by the U.S. Department of Agriculture to quantify the effects of introduced species. The researchers included more than 5 million measurements from individual trees across much of eastern North America and showed the rate at which introduced species are spreading has increased over the last two decades. Additionally, native tree diversity is on the decline in areas…
Is sauerkraut more than just a tangy topping? A new University of California, Davis, study published in Applied and Environmental Microbiology suggests that the fermented cabbage could help protect your gut, which is an essential part of overall health, supporting digestion and protecting against illness. Authors Maria Marco, professor with the Department of Food Science and Technology, and Lei Wei, a postdoctoral researcher in Marco’s lab, looked at what happens during fermentation — specifically, how the metabolites in sauerkraut compared to those…
In a groundbreaking study published in Science, a research team led by Prof. YE Jian from the Institute of Microbiology of the Chinese Academy of Sciences has identified the first mechanism of citrus resistance to citrus greening disease, or huanglongbing (HLB). Utilizing artificial intelligence (AI), the team has also developed antimicrobial peptides that offer a promising therapeutic approach to combat the disease. This discovery addresses a long-standing challenge in the agricultural community—the absence of naturally occurring HLB-resistant genes in citrus….
A new study maps how specific lactic acid bacteria can enhance both the flavour and nutritional quality of plant-based dairy alternatives. The findings may have wide-reaching perspectives for the further development of sustainable foods. Plant-based dairy alternatives – such as soy, oat, and almond drinks – are produced without animal ingredients for consumers seeking plant-based substitutes for milk and yoghurt. However, many of these products have the similar shortcomings: flavours that do not always appeal to consumers, and nutritional profiles…
A study recently published in Nature indicates that human activities have a negative effect on the biodiversity of wildlife hundreds of kilometres away. A research collaboration led by the University of Tartu assessed the health of ecosystems worldwide, considering both the number of plant species found and the dark diversity – the missing ecologically suitable species. For the study, over 200 researchers among them one scientist from the Helmholtz Centre for Environmental Research (UFZ) and the German Centre for Integrative…
Images taken from an unmanned aerial vehicle, processed with free software, help assess water stress parameters in corn experiments and select varieties that are better adapted to water shortages. A method using free software and a drone with a low-cost camera has made it possible to select drought-tolerant corn plants. The tool contributes to the selection of plants that can better withstand water stress, one of the impacts of climate change on agriculture. The results of the experiments were published in an…
This Sea Grant publication will serve as a valuable resource for fish farmers and policymakers navigating the complex legal environment of aquaculture Fish farmers across the Great Lakes states can face a confusing web of permits, policies and regulations that can hinder the growth of their operations. A new Sea Grant publication, Aquaculture Regulations in the Great Lakes, offers much-needed clarity. The report breaks down complex legal frameworks and provides practical insights to help aquaculture producers understand and navigate state and…
Fruit coated with the material developed by researchers at the University of São Paulo showed 11% less weight loss during storage and took longer to start becoming contaminated by fungi An edible biofilm, obtained from agricultural and fishing waste and developed by researchers at the São Carlos Institute of Chemistry of the University of São Paulo (IQSC-USP) in Brazil, allows the shelf life of strawberries (Fragaria x ananassa Duch.) to be extended. In laboratory tests, the researchers found that over 12…
Nitrate, pesticides, metals, plastic – agricultural soils often contain pollutants. But are there sustainable and climate-friendly ways to restore and promote soil health in agricultural land? Yes, says a research team from the Helmholtz Centre for Environmental Research (UFZ). Specific plant species could be used as cover plants for phytoremediation, i.e. to relief agricultural land from adverse pollutant impacts. In their article published in Trends in Plant Sciences, the researchers summarise the results of more than 100 scientific studies and…
Suppression of the CcMCA1 gene has potential in halting invasive plant species The parasitic vine Cuscuta campestris grows by latching onto the stems and leaves of plants and inserting organs called haustorium into the host plant tissues to draw nutrients. The haustorium is formed when ion channels in the cell membrane are stimulated during coiling and induce a reaction within the cell. Further, Cuscuta campestris has many types of ion channels, but which ones were linked to the development of…
