Researchers who study Earth’s biosphere tend to operate from one of three scientific cultures, each with distinct ways of conducting science, and which have been operating mostly independently from one another. The authors identify and explain the three cultures, and suggest that reconnecting them could help accelerate biosphere science. ​Researchers who study Earth’s biosphere tend …

Oases are important habitats and water sources for dryland regions, sustaining 10% of the world’s population despite taking up about 1.5% of land area. But in many places, climate change and anthropogenic activities threaten oases’ fragile existence. New research shows how the world’s oases have grown and shrunk over the past 25 years as water …
