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: 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 investigated the spread of antimicrobial resistance determinants (ARD) in a gentoo penguin and an Antarctic fur seal on Livingston Island. The results showed the presence of glycopeptide resistance genes in both samples, and additional resistance genes in the penguin's sample. These findings suggest a potential ocean pollution with antibiotic resistant bacteria (ARB).

Summary: In this article, empirical models for estimating daily mean air temperature in the Hurd Peninsula of Livingston Island (Antarctica) were presented using MODIS LST data and spatiotemporal variables. The models were obtained and validated using in situ meteorological stations' data and MODIS data. The results showed that the models were accurate and useful for estimating long-term trends in air temperature.

Summary: The summer climate in Maritime Antarctica is characterized by high humidity, cloudiness, and slightly above zero temperatures, which limit photosynthetic activity and result in plant communities formed by a few species. Research on pigment dynamics in two representative species in Antarctic plant communities revealed high levels of environmental stress.

Summary: Despite a long research history, knowledge of Antarctic marine benthic diatoms is fragmentary. This study reports on the species distribution of marine benthic diatoms in different coastal habitats in South Bay, Livingston Island. The study found that diatom communities are influenced by habitat type, but not by seasonality, and there are significant differences in communities between different substrata types. However, the identification of diatom species is challenging due to limited studies and confusing nomenclature history.

Summary: Research shows that the southeastern area of Livingston Island is built up by igneous rocks of the Eocene Barnard Point Pluton and related or younger dykes, with different rock varieties indicating magma mixing processes. The presence of magmatic foliation and solid-state foliation parallelizing the main foliation of the metamorphic host rocks suggests tectonically active setting for room creation and magma emplacement.

Summary: The quartz-polymetallic veins from Caleta Argentina, Livingston Island, Antarctica contain abundant minerals such as pyrite, chalcopyrite, galena, and sphalerite. Among them, chalcopyrite is the most common ore mineral, with significant concentrations of silver (average 240.51 ppm). Sphalerite contains silver (average 50.82 ppm) and gold (average 0.31 ppm), while pyrite contains trace amounts of gold (ranging from undetectable to 1.03 ppm, average 0.59 ppm) and silver (ranging from undetectable to 54.33 ppm, average 32.52 ppm). Caleta Argentina, as one of the ore occurrences in Hurd Peninsula, is correlated with other research areas such as the Bulgarian Antarctic Base, the Bulgarian Beach, and Sally Rocks.

Summary: This study examined the decomposition indicators of carbohydrates in polar soils under different vegetation cover in Livingston Island, Antarctica. The findings showed that soils with vegetation cover had higher microbial biomass and enzyme activity compared to soils without vegetation. The type of vegetation also influenced the activity of specific enzymes. The study emphasized the importance of organic carbon and nitrogen in driving the soil microbial processes.

Summary: This study aimed to compare the nutritional benefits of edible Malaysian fishes from Terengganu, Malaysia, while also conducting a taxonomical characterization and metal assessment. The heavy metal assessment revealed that the detected elements were within regulatory limits, and the fatty acids composition in the fish fillet tissues was comparable to species in similar marine ecosystems. High fatty acid values can be useful for comparing the nutritional benefits of these biodiverse and non-toxic edible Malaysian fishes.

Summary: Fishes are a valuable source of essential fatty acids for preventing cardiovascular diseases. However, the increase in fish consumption has led to a rise in fish waste, making waste disposal and recycling an important issue in line with circular economy principles. This study investigated the fatty acid profiles of different fish tissues and found that fish waste, such as liver and ovary, could be a sustainable source of high value-added nutraceuticals.
