Pliocene–Pleistocene Redox Evolution of the Peruvian Margin: A Multi‐Proxy Approach

Paleoceanography and Paleoclimatology, Volume 41, Issue 2, February 2026.
Abstract Due to upwelling of nutrient‐rich waters, the Peruvian Margin is one of the most productive regions of the global ocean, hosting one of the most pronounced and shallowest oxygen minimum zones. This combination of high productivity and low oxygen makes the Peruvian margin a critical site for reconstructing past environmental changes.

Reconstructing Environmental and Microbial Ecosystem Changes Across the Permian–Triassic Mass Extinction at Lusitaniadalen, Svalbard

Paleoceanography and Paleoclimatology, Volume 41, Issue 2, February 2026.
Abstract The Permian–Triassic environmental crisis triggered fundamental changes in marine ecosystems, culminating in the most severe biodiversity crisis of the Phanerozoic. Yet, the environmental and geochemical conditions governing the crisis and ecosystem recovery remain debated.

Airborne Bacterial Communities: Diversity, Survival Strategies and Functional Roles in the Atmosphere

Environmental Microbiology Reports, Volume 18, Issue 1, February 2026.
This mini‐review synthesises evidence on the taxonomic patterns of airborne microorganisms and the selective pressures they face. We highlight key conserved physiological traits, such as DNA repair and desiccation tolerance, which enable stress‐tolerant members to survive and suggest their potential for activity within the atmospheric environment ...
