Four new #mushroom species discovered in Sweden phys.org/news/2024-12-mushroom

The genus Phellodon (Basidiomycota #Fungi) in Europe: Four #NewSpecies, one new combination, four new typifications and a first European record ingentaconnect.com/content/wfb

"They live in #symbiosis with different host #trees on different types of #soil, some in calcareous beech #forests, others in acidic pine #bogs. However, one environmental requirement unites all the new species—their association with #OldGrowthForests."

Scottish #bog gets world heritage status bbc.com/news/articles/cv2gz1p2

After an almost 40-year campaign, a stunning but little-known UK landscape has been awarded world heritage status. The #FlowCountry of Caithness and Sutherland in the far north of #Scotland covers almost 2,000 sq km of one of the most intact and extensive blanket bog systems in the world. Blanket #bogs are wetland ecosystems created when #peat, a #soil made up of partially decayed matter, accumulates in waterlogged conditions.

Measurements from stations around the world show that #methane levels have increased significantly since the early 2000s.

According to the report, the main reason is that more methane has been released from wetland areas such as #bogs, shallow #wells , #ponds, and #lakes in tropical regions.

And as it gets warmer, more is released.

“The temperature change leads to increased microbiological activity,” researcher Stephen Matthew Platt says. He is one of the researchers behind the new study.

Processes like #decomposition in wetlands happen faster when it gets warmer.

Another reason for the increase in methane emissions is that #permafrost has begun to #thaw in the north.

“When the permafrost thaws, it also leads to more water on the surface, and this development is underway,” explains Platt.
