Current models of microbial primary succession postulate that stochasticity dominates the early stages of soil community assembly, generating phylogenetically random patterns that are lost as abiotic and biotic filters gain relevance. We hypothesized that, under severe environmental stress, abiotic filters may override stochasticity from early successional stages, inducing phylogenetic clustering due to the overrepresentation...

Soil is a major terrestrial carbon reservoir, and enhancing its carbon stock is a central strategy to mitigate climate change. Earth system models project a net soil carbon sink by 2100, the magnitude of which is still under debate, differing significantly between approaches. Radiocarbon‐based studies often suggest a limited soil carbon accumulation capacity, but these estimates are biased by the presence of ancient, radiocarb...

The growing contamination of urban areas by antimony (Sb) has sparked interest in microbial processes that modulate Sb speciation in ecosystems. The bacterial antimonite oxidase AnoA is the only oxidase known so far whose gene expression is specifically induced by Sb(III), but its annotation in public databases is currently lacking. Here, the computational search for AnoA orthologs predicted an unexpected phylogenetic distribu...
