New research reveals that paperbarks, among other trees, host abundant, specialized, and metabolically active bark-dwelling microbial communities that modulate climatically relevant gases, including methane, hydrogen, and carbon monoxide. Learn more this week in Science: scim.ag/4bp9hgl
This photograph, taken at the ephemeral wetland study site in Bogangar, Australia, shows a paperbark tree (Melaleuca quinquenervia)—a hardy, iconic Australian wetland species that is recognized by its layered, papery bark.

Tree bark has a total surface area similar to all of the land area on Earth. It is home to a wide range of microbial species unknown to science, and they can either take up or emit gases that have a warming effect on the climate
