Atacama Desert Hosts Surprising Nematode Diversity Amid Extremes

3/5/2026

Summary

Story summary

University of Cologne researchers report that the Atacama Desert in Chile, the world's driest non-polar desert, hosts diverse nematode communities.
Across six environments, the study identified 36 genera of nematodes despite minimal rainfall and high salinity.
Areas with more moisture and seasonal temperature variation support greater nematode biodiversity.
Nematodes at higher elevations reproduce asexually, suggesting an adaptive strategy in extreme conditions.
