“…In the season of summer, N2 is transported in the form of DON and nitrogen particulate matter in the suspension where the amount of nitrate is less than 1μmol/L. Not only nitrogen but also different turnover of carbon, methane, methanotropic community and other substances have been seen that all are influence greatly by the soil microbes [63][64][65][66][67][68][69][70][71][72].…”

There is a wide range of diverse soil and aquatic microbes reside in different deltas of the world that mainly exhibit in various forms such as bacteria, fungi, parasites, archaeans, actinomycetes, virus etc. They contribute to the environment in various ways to maintain the balance of natural elements, bio geological components and also help in protecting the ecological components. Microbes that are living in the soil provide plants along with environmental and natural protection from diseases and pests. They are very much essential for transforming nitrogen and nutrients into the forms that is consumable for plants. Decomposition, production of Oxygen, evolution, as well as symbiosis are the vital roles that are played by different soil and aquatic microbes. Some river deltas show maximum populations of saline soil dependent bacterial and fungal community, where as some river deltas are enriched with some specific microbes that are responsible for soil remediation. In some cases some species of hydrocarbon degrading microorganisms contribute to differences in C, N, P ratios. As the microbes are also responsible for producing different antigens as well as allergens that are mainly causative agents for varying infectious diseases, in need of its curative drugs and antibiotic medicines some microbes are involved in research studies for production of medicinal drugs and anti-allergens.

In connection with climate change and the development of natural resources in the Arctic, increasingly relevant is the problem of revealing the response of tundra vegetation to various natural and anthropogenic impacts, as well as the search for indicators for developing a system of monitoring the state of ecosystems in the Far North. The aim of this work was to describe the floristic composition and structure of plant communities, as well as to search for relationships between agrochemical indicators of soils and the species composition of plants in certain key sites of the Lena River Delta. A total of ten key sites of the Lena delta were studied. Agrochemical analysis of the soil samples was performed using standard methods. The content of biogenic and abiogenic elements was measured using an emission spectrometer. The relationship between the soil parameters and floristic composition was studied using cluster analysis. It was shown that the clustering of sites by standard agrochemical indicators was weakly expressed, while in terms of the content of elements in the mineralized samples and in water extracts the sites were grouped into two clusters at the level of 40 %÷60 % of the differences. The clustering of sites by plant species composition was very weak, and it was not possible to identify clusters with high or medium level of similarity, nor was it possible to detect similarity between cluster diagrams constructed by soil parameters and by plant species composition. As a result of the study, it is shown that the species composition of vascular plants weakly correlates with the properties of the soils of the key sites. The individual features identified manifest themselves in the form of trends and no clear patterns of interrelation of vegetation and soil parameters are discerned.
