As extreme fires transform Alaska’s boreal forest, deciduous trees put a brake on carbon loss and how fast the forest burns

A new study finds more deciduous trees like aspen are growing in after severe fires in the region, and that has some unexpected impacts.

Plants thrive in a complex world by communicating, sharing resources and transforming their environments

We may think of plants as passive life forms, but they can cooperate, share resources, send one another warnings, and distance themselves from their communities when survival depends on it.
