Many soil microbes play a vital role in ecosystems, as they help plants access nutrients and water and assist in stress tolerance such as during drought and to defend against pathogens. One such group of soil microbes are arbuscular mycorrhizal, aka AM, fungi, which are associated with the roots of approximately 70% of plant species on land. new Dartmouth-led study reports on how global climate conditions affect AM fungal spore traits and the species biogeographic patterns. The results are published in the Proceedings of the National Academy of Sciences.
Researchers have devised a new machine learning method to improve large-scale climate model projections and demonstrated that the new tool makes the models more accurate at both the global and regional level. This advance should provide policymakers with improved climate projections that can be used to inform policy and planning decisions.
Tiny droplets of sea spray generated at the ocean surface can affect the intensity and evolution of hurricanes and other tropical storms.
Their impact, however, is not well understood because of the difficulty of measuring spray concentration and the size and velocity of individual droplets under high wind conditions.
At The University of Texas at Dallas, researchers are studying sea spray, particularly spume, or foam, droplets, in the lab to develop a model based on machine learning to improve hurricane forecasting. The model incorporates the effects of the spray generation function, which quantifies the rate at which droplets form.
