Contrasting stability of fungal and bacterial communities during long-term decomposition of fungal necromass in Arctic tundra

Scientists studied how dead fungal material breaks down in Arctic soil over three years. They found that melanized fungi, especially Pseudogymnoascus, are key decomposers that help break down tough fungal material containing melanin. While bacterial diversity increased over time, the fungal community remained relatively stable. Even after three years, about 20% of the fungal material remained undecomposed, suggesting it can help store carbon in Arctic soils.

Warming and Reduced Rainfall Alter Fungal Necromass Decomposition Rates and Associated Microbial Community Composition and Functioning at a Temperate–Boreal Forest Ecotone

Scientists studied how climate change affects the breakdown of dead fungal material in forest soils. They found that warmer temperatures and less rainfall initially speed up decomposition in the first two weeks, but then slow it down later. The microbial communities eating the dead fungi also changed over time, with different bacteria and fungi becoming dominant depending on soil moisture and temperature conditions.
