Summary: This study analyzed the phylogeny, ecology, and biogeography of the "marine Geitlerinema" cluster representatives and identified two subclusters with distinct distributions. The ecological and geographical diversity of the Sodalinema genus was expanded, leading to the proposal of three new species. Additionally, a new genus and species, Baaleninema simplex gen. et sp. nov., were described within the PCC7105 Glade, contributing to the clarification of the confusion surrounding the "marine Geitlerinema" group.

Summary: Two cyanobacterial morphotypes isolated from Signy Island, Antarctica were characterized as belonging to the genus Wilmottia, specifically within the clade of W. murrayi. This extends the known distribution of W. murrayi in Antarctica and suggests a new combination, W. arthurensis.

Summary: Desert regions are highly sensitive to climatic changes, especially in terms of precipitation. The study found that physiological properties of biocrusts, such as photosynthetic pigments and antioxidant enzyme activities, are significantly influenced by the amount of annual precipitation. Both moss and cyanobacteria crusts exhibit strong adaptability to changes in precipitation, indicating their potential resilience in the face of climate change.

Summary: Understanding the community structure of Arctic phytoplankton is crucial for predicting the response of Arctic ecosystems to ocean warming. This study investigated the diversity and biogeography of diatoms in the Svalbard area and found that they exhibit different biogeographic distribution types and are structured by local environmental gradients. The finer biogeographic patterns observed within certain genotypes suggest that they can serve as indicators of the influence of Atlantic waters on the phytoplankton community in the region.

Summary: This study utilized benthic communities of hydroids as a model to investigate the biodiversity-biogeographic connections between southern South America and Antarctica, identifying hotspots of rich biodiversity at risk of depletion and critical regions susceptible to loss of diversity. The analysis revealed a more stratified and complex biogeographic structure, with the Magellan area and Scotia Arc showing transitional characteristics.

Summary: Badnaviruses are serious pathogens of global crops, and their endogenous sequences pose challenges to nucleic acid-based diagnostic methods and international germplasm movement. Yam is a major affected food security crop, and this study developed a PCR-DGGE method to detect and analyze endogenous badnaviral sequences in yam.

Summary: This paper describes the biodiversity of cyanobacteria and microalgae in biological soil crusts (BSC) in different mountain vegetation types at the Northern Urals. The study found that the species diversity and composition of these algae are influenced by environmental factors such as altitude, soil pH and humidity, and illumination. The classification diversity of algae varies with different vegetation types at different altitudes. The dominant species of BSC algae is specific to each type of plant community and reflects habitat conditions. Furthermore, the species diversity and morphological organization of BSC algae can be used as a criterion for assessing climatic changes in high latitudes and mountain regions.

Summary: This study evaluated the distribution of chironomids in the Arctic region and found that environmental controls play a major role in influencing chironomid assemblages within each region, while spatial controls are significant only when crossing between regions. Environmental gradients, especially temperature, define species distributions within each region, with spatial processes combining with environmental gradients in determining the mix of species characterizing each broad and unique island region.

Summary: The feasibility of using biogas to enhance oil recovery in the hypersaline Qinghai oil field was studied. The use of molasses as a carbon source effectively promoted gas production. Addition of nitrate eliminated sulfate-reducing bacteria, which had a significant impact on the application of MEOR.

Summary: The study found that AgNPs affected the structure and tolerance of SBC, but did not increase tolerance on a second exposure. AgNO3 was more effective in inhibiting SBC growth than AgNPs, both in a dose-dependent manner.

Summary: Nitrification-denitrification is an environmentally friendly and cost-effective method for treating landfill leachates. This study found that the nitritation rates of nitrifying biomass were reduced after adaptation to landfill leachates with heavy metals and high salt concentrations. The analysis of biomass samples revealed the presence of specific bacterial genera and families involved in nitritation and denitrification processes.

Summary: The present study showed that dietary supplementation of PHB did not affect the growth parameters of rainbow trout fingerlings, but significantly reduced total coliform counts and increased intestinal villus length and width. This suggests that PHB can be used as an alternative microbial control agent for improving intestinal health in rainbow trout.

Summary: Agronomic practices such as long-term plastic film mulching and fertilization significantly influence soil microbial communities. Ammonia-oxidizing archaea dominate in areas where these practices are employed, especially in non-fertilized treatments, leading to increased bacterial richness.

Summary: Research on the cyanobacterial strain 'Fischerella ambigua 108b' unveiled new bioactive compounds and led to the classification of the strain as Symphyonema bifilamentata sp. nov. 97.28 through a polyphasic approach. This newly classified strain sheds light on the bioactive metabolites of heterocytous and true-branching cyanobacteria, suggesting its placement into a separate genus.

Summary: This study identified the taxonomic position of strain PCC 6712 using morphology, genome analysis, and phylogeny, as well as detected shared genes with its closest relative and potential bioactive gene clusters. The presence of a full set of nitrogen fixation genes in PCC 6712, despite its inability to grow on nitrogen-free medium, was also highlighted. Additionally, a comparison of genes responsible for multicellularity revealed important aspects of cyanobacterial taxonomy.

Summary: This study aims to determine a potential niche concept for the genus Cyanocohniella based on salt tolerance. Results showed that C. rudolphia sp. nov. and C. crotaloides strains exhibited optimum growth at 4% NaCl concentration, supporting the hypothesis that the genus may have a marine origin and expanded colonization to salty terrestrial habitats. The ecological and biotechnological relevance of the findings were discussed.
