Short summary
Short summary
The "two water-worlds hypothesis" has attracted significant public attention because it is an accessible way to describe the partitioning of water sources within catchments. This manuscript adds a new degree of complexity to that idea by recognizing that co-occurring tree species, which root at different depths, also use different water sources. So it leads to at least three water worlds.

Short summary
Short summary
Ecological processes respond to changes in rainfall conditions. Competition and stress created by water availability are two primary components at two ends of the rainfall gradient. In wetter areas, plants compete for resources, while in drier regions, stress limits growth. The complex interaction between plant characters and their response to growth conditions governs ecosystem processes. These findings can be used to understand how future rainfall changes could impact ecosystems.

Short summary
This study found climate to be a driving force for increasing per area emissions of greenhouse gases and removal of important nutrients from high-latitude forests due to wildfire. It used detailed direct measurements over a large area to uncover patterns and mechanisms of restructuring of forest carbon and nitrogen pools that are extrapolatable to larger regions. It also takes a step forward in filling gaps in global knowledge of northern forest response to climate-change-strengthened wildfires.
