Responses of the Natural Phytoplankton Assemblage to Patagonian Dust Input and Anthropogenic Changes in the Southern Ocean

open access: yesEarth's Future, Volume 13, Issue 6, June 2025.
Abstract The cumulative effects of multi‐faceted changes on the phytoplankton community of the Southern Ocean (SO) are not yet known, which is a major limitation to predicting the future direction of the biological carbon pump. Thus, our study aimed to estimate the effects of intensified Patagonian dust inputs, warming and acidification on the growth ...

Intrathalline Fungal and Bacterial Diversity Is Uncovered in Antarctic Lichen Symbioses

open access: yesEnvironmental Microbiology Reports, Volume 17, Issue 3, June 2025.
Antarctic endemic lichens host a greater biodiversity and rare species of fungi and bacteria within the thallus than cosmopolitan lichens. ABSTRACT Although the Antarctic continent represents one of the most hostile environments on earth, microbial life has adapted to cope with these extreme conditions.

Bioavailable Dissolved Organic Carbon Serves as a Key Regulator of Phosphorus Dynamics in Stream Biofilms

open access: yesEnvironmental Microbiology Reports, Volume 17, Issue 3, June 2025.
We tested the effect of bioavailable DOC on P entrapment in biofilms and in biofilm P‐regulation mechanisms such as polyphosphate accumulation and alkaline phosphatase activity in semi‐natural experimental flumes. Our results show that intracellular P entrapment is limited by bioavailable DOC, while extracellular P entrapment is independent of ...

Adaptation of Marine Heterotrophic Protists to Long‐Term Warming Selection

open access: yesGlobal Change Biology, Volume 31, Issue 6, June 2025.
Our study unraveled profitable adaptations of marine protozoa to long‐term warming. The optimal temperature, maximum growth rates, cell homeostasis, and cell size significantly increased after warming adaptation, suggesting a resilient future for this functional group.
