Radiocaesium Contamination of Mushrooms at High- and Low-Level Chernobyl Exposure Sites and Its Consequences for Public Health

mycolabadmin

A study examined how much radioactive cesium collected in wild mushrooms from areas affected by the 1986 Chernobyl nuclear accident in Czech Republic. The findings showed that while mushrooms in the most contaminated area accumulated more radioactivity than those in less affected areas, eating these mushrooms would not cause significant health risks to most people. The research helps experts understand how to safely assess radioactive contamination in wild foods after nuclear accidents.

Plasticity of symbiotroph-saprotroph lifestyles of Piloderma croceum associated with Quercus robur L.

mycolabadmin

A fungus called Piloderma croceum can switch between two lifestyles: breaking down dead wood to get nutrients, and forming beneficial partnerships with living oak tree roots. This research shows that dead wood colonized by this fungus acts like a ‘bank’ of fungal spores that can later establish symbiotic relationships with new trees. This process helps forests thrive by improving how trees obtain nutrients from soil. Understanding this dual lifestyle reveals how deadwood plays an important role in forest health beyond just decomposition.

Plasticity of symbiotroph-saprotroph lifestyles of Piloderma croceum associated with Quercus robur L

This research reveals that a common forest fungus called Piloderma croceum can switch between two different lifestyles: breaking down dead wood to obtain nutrients, and forming beneficial partnerships with living oak tree roots. The study shows that dead wood colonized by this fungus serves as a natural ‘seed bank’ for these fungi, allowing them to later colonize new trees. This discovery suggests that protecting deadwood in forests may indirectly help forests grow healthier by supporting the fungi that help trees absorb nutrients.
