Nutrient enrichment typically causes local plant diversity declines. A common but untested expectation is that nutrient enrichment also reduces variation in nutrient conditions among localities and selects for a smaller pool of species, causing greater diversity declines at larger than local scales and thus biotic homogenization. Here we apply a framework that links changes in species richness across scales to changes in the numbers of spatially restricted and widespread species for a standardized nutrient addition experiment across 72 grasslands on six continents. Overall, we find proportionally similar species loss at local and larger scales, suggesting similar declines of spatially restricted and widespread species, and no biotic homogenization after 4 years and up to 14 years of treatment. These patterns of diversity changes are generally consistent across species groups. Thus, nutrient enrichment poses threats to plant diversity, including for widespread species that are often critical for ecosystem functions.

Climate change is challenging agriculture and food security due to the limited adaptability of domesticated crops. While plant range shifts along latitudinal and altitudinal gradients are well-documented, their impacts on belowground microbial communities and plant adaptability remain poorly understood.

This exploratory study surveyed seven contaminated brownfields and Superfund sites in Southern California to identify locally adapted species tolerant of mixed organic and metal contamination under arid and semi-arid conditions. Five novel native plants, including Brickellia californica, Baccharis salicifolia, Baccharis sarothroides, Eriogonum fasciculatum, and Heterotheca grandiflora were identified as hyperaccumulators of copper (Cu), alongside a non-native species from the Asteraceae family, Helminthotheca echioides. Additional metal-accumulating plants (including native plants) for lead (Pb), chromium (Cr), arsenic (As), and nickel (Ni) were identified, and warrant further evaluation for their phytoremediation potential.

Livestock wastewater is a critical reservoir of antibiotic resistance genes (ARGs) that poses significant public health risks. This study comprehensively evaluated the seasonal dynamics and associated risks of ARGs in a full-scale livestock wastewater treatment plant using an integrated metagenomic and metatranscriptomic approach. The results showed that untreated livestock wastewater harbored high abundance (4.

The coordination of floral developmental stages with the environment is important for reproductive success and the optimization of crop yields. The timing of different developmental stages contributes to final yield potential with optimal adaptation enabling development to proceed without being impacted by seasonal weather events, including frosts or end of season drought. Here we characterise the role of FLOWERING LOCUS T 3 (FT3) in hexaploid bread wheat (Triticum aestivum) during the early stages of floral development.
