In future, it will be increasingly important to be able to predict the yields of individual varieties of cereals such as wheat as accurately as possible in a given environment. An international research team led by the IPK Leibniz Institute has compiled, processed and analyzed extensive data sets for this purpose. Ultimately, Big Data was able to double the prediction accuracy for yield.
3D tumors that disintegrate within a few days thanks to the action of a well-known omega-3 (DHA, found mainly in fish) -- this is the exceptional discovery by University of Louvain researchers. Hungry for fatty acids, tumor cells in acidosis gorge themselves on DHA but are unable to store it correctly and literally poison themselves. The result? They die.
New research by Monash University scientists from the School of Biological Sciences published today in Ecological Solutions and Evidence shows that the richness and abundance of birds is much reduced in areas with dense Pittosporum canopies.
Plants are constantly exposed to microbes: pathogens that cause disease, commensals that cause no harm or benefit, and mutualists that promote plant growth or help fend off pathogens. For example, most land plants can form positive relationships with arbuscular mycorrhizal fungi to improve nutrient uptake. How plants fight off pathogens without also killing beneficial microbes or wasting energy on commensal microbes is a largely unanswered question.
Plant species with thick and dense roots are more likely to occur in warm climates, while species with thin and low density roots are more likely to occur in cold climates -- a classic trade-off. By contrast, forest species with large-diameter roots and high root tissue density were more commonly associated with dry climates, but species with the opposite trait values were not associated with wet climates. Instead, a diversity of root traits occurred in warm or wet climates.
Since the 1990s, mid-infrared testing of milk urea nitrogen (MUN) has been the most efficient and least invasive way to measure nitrogen use by dairy cows in large numbers. In a recent article in the Journal of Dairy Science, researchers from Cornell University report the development of a robust new set of MUN calibration reference samples to improve accuracy of MUN measurement.
Researchers at the University of Central Florida have published a first- of-its-kind study that shows that near-infrared (NIR) spectrum cameras can help python hunters more effectively track down these invasive snakes, especially at night.
Global ecosystem restoration efforts are often measured by billions of trees planted or square kilometers of land restored. But there is a critical void in the agenda: the social and political dimensions that make restoration a success.
In a new study, an international team of plant researchers including the Institute of Botany at TU Dresden has discovered an unusual and previously unknown reproductive strategy in plants: the Greek pipevine species 'Aristolochia microstoma' produces a unique mixture of volatiles that resembles the smell of dead and decaying insects to attract the pollinating fly genus 'Megaselia' (also known as 'coffin flies') to its trap-flowers. The study was recently published in the open-access journal 'Frontiers'.
The Exeter team's review summarizes and critically appraises the current approaches that study the concentrations of antimicrobials that increase AMR. By collating and assessing available data, they have recommended what these safe thresholds could be, to enable governments to act to reduce them.
