Microbes shape life on Earth, from nutrient cycling in soils to human health. Over the past decade, millions of microbiome samples have been sequenced across environments. But differences in methods and processing have made global comparisons difficult.
Now, MicrobeAtlas, brings together 2.4 million uniformly processed microbial communities into a single, harmonised resource, enabling globe-spanning ecological discovery at an unprecedented scale.
This NCCR Microbiomes-supported effort integrates 16S/18S and metagenomic data, links taxa to genomes and culture collections, and provides rich environmental and geographic metadata, all explorable via an interactive website.
🔑 Key findings
➤ Microbial communities cluster strongly by environment (animal, aquatic, soil, plant), yet show striking fine-scale ecological structure.
➤ Soils and aquatic systems emerge as global diversity hotspots but remain heavily under-characterised taxonomically.
➤ The vast majority of detected taxa lack cultured representatives or genomes, highlighting the scale of microbial “dark matter.”
➤ Clear biogeographic trends appear across continents and latitudes, including tropical marine diversity peaks.
➤ Habitat generalism is unevenly distributed: some families (e.g., Pseudomonadaceae, Bacillaceae) contain highly adaptable generalists, while others are strongly specialised.
➤ Sampling biases are evident with overrepresentation of animal microbiomes and northern mid-latitudes, and undersampling of oceans, polar regions, and the Southern Hemisphere.
💡 Why this matters
Microbiome research has often been fragmented; siloed by habitat, sequencing method, or individual studies. MicrobeAtlas changes this by enabling:
- Cross-environment tracking of taxa
- Global biogeographic analyses
- Identification of ecological generalists and specialists
- Discovery prioritisation for uncultured and understudied lineages
- Detection of geographic and ecosystem blind spots
With an upcoming expansion to over 6 million samples, this resource lays the foundation for truly planetary-scale microbiome science
