Fungal Spore Seasons Advanced Across the US Over Two Decades of Climate Change

Scientists studied fungal spores in the air across the United States from 2003 to 2022 and found that spore seasons are starting earlier due to climate change, particularly from warmer temperatures. These airborne fungal spores can trigger allergies and asthma symptoms in sensitive people. The research shows the amount of spores in the air is decreasing, but they arrive sooner in the year, which has important implications for managing allergies and public health.

Advancing automated identification of airborne fungal spores: guidelines for cultivation and reference dataset creation

Scientists developed systematic methods to grow and collect fungal spores in controlled conditions, then test them with automated air monitoring devices. Using two different monitoring systems that analyze spore images and fluorescence properties, they trained computer algorithms to recognize different fungal species. This work creates standardized guidelines that will help hospitals, allergy clinics, and agricultural services automatically detect and identify airborne fungal spores, which are important for managing allergies and plant diseases.

Diurnal Release of Airborne Pathogen Spores in Greenhouses via the Synergistic Effects of Relative Humidity and Wind

In greenhouses, cucumber and vegetable diseases spread explosively due to the combined effects of changing humidity and wind. This research reveals that when humidity drops during the day, fungal spores shrink and detach from diseased leaves through jerking movements. Even gentle wind can carry these detached spores to healthy nearby plants, causing rapid disease spread. By understanding this mechanism, farmers can implement better disease control by managing humidity and ventilation strategically.
