Boreal forests are heading for an open state.
Proc Natl Acad Sci U S A

The boreal forest biome is warming four times faster than the global average. Changes so far are moderate, but time lags in responses may transiently maintain forest states which are no longer supported by current environmental conditions. Here, we explore whether tree cover dynamics hint at the state to which the biome may be shifting.

The North American boreal forest is a massive ecosystem, and its keystone herbivore is the snowshoe hare (Lepus americanus). Hares are exposed to considerable environmental extremes in diet and weather, food availability, and predation risk. Gut microbiomes have been suggested to facilitate adaptive animal responses to environmental change, but severe environmental challenges to homeostasis can also disrupt host-microbiome relationships.

Article Synopsis
- Restoration of peatlands can lead to shifts in plant communities similar to natural, pristine conditions.
- Traditional field monitoring of vegetation is too labor-intensive for all sites; instead, remote sensing offers a more efficient option.
- Using data from Finnish peatlands and satellite imagery, researchers found that certain optical satellite images effectively track vegetation changes, especially in less densely forested areas.
Phylogenomic analyses shed new light on the spatiotemporal evolution of global larches: Implications for the dynamics of boreal forests.

As the Earth warms, understanding the long-term dynamics of forest ecosystems is essential for guiding forest management and biodiversity conservation. Insights from past dynamics may provide valuable lessons for managing today's forests. Here, we investigated the spatiotemporal evolution of global larches to gain further insights into how boreal forests change over time.

Boreal forests form the largest terrestrial biome globally. Climate change is expected to induce large changes in vegetation of high latitude ecosystems, but there is considerable uncertainty about where, when, and how those changes will occur. Such vegetation change produces major feedback to the climate system, including by modifying albedo (reflectivity).
