Fungal Assemblages in Northern Elms—Impacts of Host Identity and Health, Growth Environment, and Presence of Dutch Elm Disease

mycolabadmin

This study examined the different fungi living in elm tree shoots to understand why some elm species are more resistant to Dutch elm disease than others. Researchers found that healthy elms host fewer fungal species compared to diseased trees, and that fungal communities differ significantly between elm species and urban versus rural locations. Importantly, a fungus called Sphaeropsis ulmicola appears to be a significant emerging threat to elms in northern Europe, separate from the classic Dutch elm disease pathogen.

This study examined the fungi living in elm tree shoots to understand how different elm species, tree health, and location affect fungal communities. Researchers found that diseased elms had more diverse fungi than healthy ones, and that a fungus called Sphaeropsis ulmicola may be as damaging as the classic Dutch elm disease pathogen. Urban elm trees hosted more different types of fungi than rural ones, suggesting that city conditions influence which fungi can grow on elms.

Genomic Exploration of Climate-driven Evolution and Evolutionary Convergence in Forest Pathogens

This study examined three fungal diseases that harm forests to understand how they adapt to different climate conditions. Researchers found that all three pathogens rely on similar genetic changes to adapt to wet and humid environments, despite being very different species. Using computer models, they predicted how these diseases might spread differently as climate changes in the future, which could help forest managers prepare and protect trees.
