Primary productivity declines when species composition and climate are mismatched

The paper examines how community-climate disequilibrium affects net primary productivity in rangeland ecosystems, finding that mismatched communities are less productive.

Taking genomics outdoors: linking local adaptation, trait variation, and gene expression in grass ecotypes across a rainfall gradient

The paper links gene expression and trait variation to drought responses in grass ecotypes across a rainfall gradient, confirming local adaptation and identifying adaptive strategies.

Interaction of plant-derived metabolites and rhizobiome functions enhances drought stress tolerance

This study shows that plant-derived metabolites interact with rhizobiome functions to enhance drought stress tolerance by recruiting microbes with stress-relief capabilities.

Plant host identity drives Andropogon gerardii rhizobiome assembly strategies under increasing abiotic stress

This study shows that regional precipitation significantly influences the microbial communities in the rhizosphere of Andropogon gerardii, with arid regions showing more stochastic microbial assembly and host-benefiting taxa.

Bacterial but not fungal rhizosphere communities differ among perennial grass ecotypes under abiotic environmental stress

This study compares bacterial and fungal rhizobiomes across three ecotypes of Andropogon gerardii under drought stress, finding distinct bacterial communities but not fungal ones.
