This study investigates how horizontal gene transfer and selection drive microbial adaptation in Antarctic soils, finding widespread HGT of aerotrophy-related genes and strong purifying selection.

This study shows that Antarctic soil bacteria can consume trace gases like H2 and CO across wide temperature ranges, with potential increases in activity under future climate scenarios.

This study identifies aridity as the primary driver of microbial community structure and biogeochemical activities in deserts across seven continents.

This study identifies aerotrophy as a primary energy source in caves, revealing microbial use of atmospheric trace gases for continuous primary production.

The paper reveals a global north-south increase in bird endemism, driven by southern hemisphere landmass fragmentation and diversity peaks.

The paper analyzes 115 years of alien species introduction data in Antarctica to assess the effectiveness of biosecurity policies, finding slowing introduction rates and highlighting the need for stricter enforcement.

This study tests whether an economic spectrum explains variation in ant ecological strategies, finding parallels with plant leaf economics spectra.

The paper assesses Antarctica's wilderness and finds it has declined, excluding much biodiversity, but suggests increased regulation could reverse this trend.
