Leaves are vital trees organs that support many important functions. A recent study published in PNAS found that each tree species in tropical rainforests possesses distinctive bacterial communities – called microbiomes – on their leaves. Understanding how leaf microbiomes vary among species may in the future be applied for maintaining healthy forests and predicting how forests will react to climate change.

Seagrass meadows form important parts of many ocean ecosystems, but is disappearing due to human impacts.
