Global Underground Fungal Network Mapped by Scientists for the First Time

Mycorrhizal Networks: Breakthrough Insights

According to НВ — Техно: On June 13, researchers released a landmark study revealing a global map of the subterranean fungal web known as the mycorrhizal network-a system that has supported plant life for at least 450 million years. An international team compiled data from 322 scientific studies and analyzed over 16,000 soil samples to create this comprehensive map. They estimate that the top 15 centimeters of soil contain roughly 110 quadrillion kilometers of fungal threads, with the entire network weighing approximately 300 million tons.

The findings show that around 70% of all plant species depend on mycorrhizal symbiosis. The scientists used more than 4,000 measurements of fungal thread density and applied machine learning techniques to make predictions. Robotic systems measured the thickness of over 300,000 living fungal filaments.

Why Mycorrhizal Networks Matter

The highest density of these networks was found in grasslands, prairies, steppes, and wetlands, which harbor about 40% of the world's biomass of arbuscular mycorrhizal fungi. In contrast, agricultural lands show a 47% lower density of fungal webs. Notably, a single teaspoon of soil can contain up to 10 meters of mycorrhizal network.

“Mycorrhizal fungi have shaped life on Earth for hundreds of millions of years, but science still doesn't fully understand how these living transport systems are distributed across the planet.”

According to Justin Stewart, 'the importance and scale of these fungi can hardly be overstated.' This research opens new avenues for studying the mycorrhizal network and its impact on Earth's ecosystems.

The results highlight the critical role of mycorrhizal networks not only for plants but for entire ecosystems. Given that roughly 70% of plants rely on fungal symbiosis, understanding these networks could have far-reaching implications for agriculture and natural resource conservation. As climate change and population growth intensify, studying how fungi can boost the resilience of agroecosystems becomes increasingly urgent.

Understanding the vastness of the mycorrhizal network is crucial for appreciating its ecological significance. A related study highlights the immense scale of these underground fungal systems, revealing how they influence biodiversity and plant health.
