Figure 9: Examples of Mollisols (grassland soils) formed from loess. Both soils have mean annual precipitation of 450 mm. The Ustoll (a) has an ustic soil moisture regime and the Xeroll (b) has a ...

Rapid erosion due to human activity, such as grazing livestock and farming, has stripped the Alps of almost all the soil formed since the retreat of the glaciers. This soil developed over millennia as ...

Shrinking glaciers expose new land in the Arctic, creating unique ecosystems. Researchers studied how microbes colonize these barren landscapes. The study reveals a crucial role for specific fungal ...

In certain trees, soils can form along branches and can support varied plant and animal life. However, what conditions these ‘canopy soils’ form in, and what kind of biodiversity they support, has ...

Shale Hills in central Pennsylvania is already a busy area in Penn State’s managed forest lands, but now a five-year $4.2 million National Science Foundation Grant will make it even busier as ...

Canopy soils that form on tree branches contain three times more carbon than soils on the ground in Costa Rica, potentially serving as an important carbon sink around the world. New research reveals a ...
