Article Synopsis
- * Sites with warmer, wetter conditions and more species generally saw increased biomass, while arid, species-poor areas experienced declines, alongside notable changes in seasonal plant growth patterns.
- * Factors like grazing and nutrient input didn't consistently predict biomass changes, indicating that grasslands are undergoing substantial transformations that could affect food security, biodiversity, and carbon storage, particularly in dry regions.
Phosphorus (P) for carbon (C) exchange is the pivotal function of arbuscular mycorrhiza (AM), but how this exchange varies with soil P availability and among co-occurring plants in complex communities is still largely unknown. We collected intact plant communities in two regions differing c. 10-fold in labile inorganic P.

In semiarid cropping systems of the Northern Great Plains, there is a lack of knowledge to how ground beetles are affected by diversified cover crop rotations. In a 2-yr study (2018 and 2019), our experiment was a restricted-randomization strip-plot design, comprising summer fallow, an early-season cover crop mixture (five species), and a mid-season cover crop mixture (seven species), with three cover crop termination methods (i.
