Caribou gut parasites indirectly create a greener tundra
Caribou merely sickened by parasites eat less vegetation, allowing plants to flourish.

Fungi may be crucial to storing carbon in soil as the Earth warms
Fungi help soil-making bacteria churn out carbon compounds that are resilient to heat, keeping those compounds in the ground, a study suggests.
