Linking fungal traits to climate

What is it about?

This study investigates an important group of soil fungi called arbuscular mycorrhizal (AM) fungi, which associate with the roots of most land plants. These fungi help with plant nutrient uptake and stress tolerance, playing a vital role in plant growth and the health of ecosystems. We focused on the traits of their spores, which are tiny, seed-like structures fungi use to disperse and survive in the soil. Using a global database of spore traits along with climate and location data, we asked: how does climate influence these traits? We found that spore traits like volume, wall thickness, and color display climate-related patterns. For example, larger spores are more common in warm, wet areas. These large spores may help fungi establish quickly in rich soils but are less likely to spread across wide or variable environments. Our findings suggest that climate acts as a filter by favoring certain fungal traits under specific climatic conditions.

Why is it important?

These findings have significant implications for agriculture, restoration, and land management. AM fungi support plant nutrient uptake and stress resistance, but as climate changes, shifts in fungal traits could influence their ability to colonize roots, supply nutrients, and persist in soils. In agriculture, understanding climate-trait relationships can help match crops with compatible fungal partners and guide sustainable farming practices amid changing environmental conditions.
