Summary: In the South Shetland Islands, geological studies have greatly contributed to the understanding of its geological evolution. However, little research has been done on the correlation of geological units throughout the archipelago. This study provides a lithostratigraphical correlation and a new geological map for the South Shetland Islands, revealing three main stages of geological and environmental evolution.

Summary: This study characterized the virome fraction of Antarctic freshwater ecosystems using shotgun metagenomic analysis. The results showed that DNA viruses were dominant, with Caudovirales being the most prevalent viral order. Additionally, uncategorized ssRNA(+) viruses were found in the lakes of Ardley Island. Bacterio-phages infecting the phylum Firmicutes and Siphoviridae were predominant in most lakes. Functional analysis revealed a prevalence of unknown proteins in the virome.

Summary: This study investigated the composition of diatom communities in Antarctic macroalgae, revealing a higher species richness of epiphytic diatoms on Deception Island and richer diatom assemblages on individual macroalgal specimens on Livingston Island. The unique volcanic environment of Deception Island may contribute to the higher diversity of ecological niches and the overall species richness and diversity observed in this study.

Summary: Despite human contamination in Whalers Bay soil, the volcanic soil heavy metal concentration of Deception Island has little biological influence on resistome genes. Whalers Bay has a higher diversity of antibiotic, biocide, and heavy metal resistance classes in its microbiomes compared to other areas.

Summary: Microdebris are present in the Southern Ocean, and this study assessed the distribution and composition of microdebris in two bays of Livingston Island. The results indicate that nearshore waters of Livingston Island are susceptible to the accumulation and retention of microdebris, with local activities being the main source of contamination.

Summary: Contaminant levels are lower in Antarctica due to low anthropogenic activities, with the northern region of the Antarctic Peninsula experiencing the most pressure. Penguins in different locations and species showed variations in trace element concentrations and stable isotope values influenced by geographical, intraspecific (ontogenetic and gender-related), and interspecific differences in feeding habits. The bioaccumulation of trace elements in penguins may also be influenced by natural enrichment in the environment as well as human activities.

Summary: Pinnipeds are found to act as biovector organisms of trace elements and rare earth elements through feces in remote environments. Further studies are needed to explore their actual impacts and long-term fate in the environment.

Summary: This research reports on the concentrations of PBDEs and MeO-PBDEs in three species of notothenioid fish from the South Shetland Islands in Antarctica. The study found significant differences in the accumulation of MeO-BDEs among the species, with feeding ecology traits explaining the patterns of accumulation. The accumulation of PBDEs was not specific to species or tissues, highlighting the importance of species-specificity in MeO-PBDE accumulation.

Summary: The Northern region of the Antarctic Peninsula has the highest human presence in West Antarctica, which poses a potential risk of chemical pollution. This study conducted monitoring of POPs in surface sediment to evaluate the environmental status of this ecologically relevant and sensitive area. Although some evidence of pollution was found in certain areas, a clear pollution pattern was not identified.

Summary: Research on protease-producing bacteria in Antarctic soil revealed that these bacteria mainly secrete serine proteases and metalloproteases, with predominant genera such as Arthrobacter, Chryseobacterium, Flavobacterium, and Pseudomonas, showing a large distribution in activity.

Summary: Monitoring and inventorying of proglacial lakes in the Maritime Antarctica region is important for understanding the impact of climate change. This study used Landsat images to create a map of lakes in ice-free areas of the South Shetlands Islands and found that the number and area of lakes have been increasing over time. The study also observed changes in elevation and distance from glaciers and the sea.

Summary: This study identified fungi on archaeological sealers' artifacts from the 19th century on Livingston Island in Antarctica. Various types of fungi were found, some likely contaminated during laboratory processes, while others were cold-tolerant and could continue growing on the objects at low temperatures. Preventive measures should be taken to avoid microbial contamination and preserve the Antarctic archaeological heritage.

Summary: This study used DNA metabarcoding to assess uncultured algal diversity at two sites on Deception Island, Antarctica, finding significant differences in algal diversity, richness, and abundance between a protected site and a site heavily impacted by human activities. The presence of DNA from non-native species raises concerns about how human impacts may affect future biological colonization processes in Antarctica.

Summary: This study presents the results of excavations and analyses of two abandoned rookeries in the South Shetland Islands, West Antarctica. The findings provide insights into the taxonomic composition, transport and preservation of bones and eggshells, and inform the reconstruction of past nesting areas.
