Interactive effects of UV radiation and water deficit on production characteristics in upland grassland and their estimation by proximity sensing Open
Since water deficit (WD) and ultraviolet radiation (UV) trigger similar protective mechanisms in plants, we tested the hypothesis that UV modulates grassland acclimation to WD, mainly through changes in the root/shoot (R/S) ratio, enhances…

Disentangling climate from soil nutrient effects on plant biomass production using a multispecies phytometer Open
Plant community biomass production is co‐dependent on climatic and edaphic factors that are often covarying and non‐independent. Disentangling how these factors act in isolation is challenging, especially along large climatic gradients tha…
