Across 74 temperate grassland plots in Germany, 28 coexisting herbaceous species consistently differ in water uptake depth, with niche differentiation strongest in drier conditions within the upper 30 cm of soil.
- Why it matters: Hydrological niche differentiation depends on whether coexisting species partition water use vertically in the shallow soil they share, but the conditions and resolution of this partitioning remain unclear.
- What they did: In three German regions, the study measured soil water content at multiple depths and used oxygen stable isotopes to quantify water uptake depth for 28 species across 74 plots.
- The result: Uptake depth differences were largely confined to the upper 30 cm and increased as overall soil moisture declined, while soil moisture vertical distribution was unrelated to uptake depth or species differentiation; broad functional groups overlapped substantially.
