Special Issue Information

Dear Colleagues,

Despite the efforts of governments and conservation organizations to protect rivers, lakes, wetlands, and subsurface aquifers, many of them are being severely damaged by human activities. Consequently, monitoring, planning, or assessing the performance of remediation measures to guard freshwater ecosystems constitutes an urgent need and a challenge in environmental protection.

Microbial communities are sensitive to all disturbances of their habitat. The recent development of new methods for estimating microbial biodiversity and function enables detecting factors responsible for shaping specific microbial community composition and role in relation to environmental factors, including those of anthropogenic origin.

Therefore, searching for indicators of ecosystem function, and assessing community structure to identify microorganisms uniquely associated with it, may be crucial for understanding unwanted changes and help to solve the problem of reservoir contamination and subsequent restoration.

The special issue “Microbiodiversity profiling as a first step towards better management of freshwater ecosystems” within Sustainability aims to highlight those aspects of the biodiversity of microbial communities in freshwater ecosystems (lakes, rivers, and subsurface environments) that may be used to develop better practices for their conservation and management. All researchers in the field are invited to contribute with their original, unpublished works. Both research and review papers are welcome.

Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Sustainability is an international peer-reviewed open access semimonthly journal published by MDPI.

Bacteria, an integral part of aquatic ecosystems, are responsible for the circulation of matter and flow of energy. Since bacterioplankton rapidly responds to any natural and human-induced disturbances in the environment, it can serve as a bioindicator of these changes. Knowing factors that shape the microbial community structure may help the sustainable management of the water environment. However, the identification of environmental signals affecting the structure and function of bacterioplankton is still a challenge. The study analyses the impact of environmental variables on basic microbial parameters, which determines the effectiveness of ecological processes in rivers. Measurements of bacterioplankton abundance (BA) and extracellular enzyme activity (EEA) were based on fluorescent markers. The bacterial community structure was determined by 16S rRNA gene amplicon sequencing (Illumina). The results indicate spatial variation in bacterioplankton abundance. Temporal variation was not significant. Lipase and aminopeptidase had the highest level of activity. EEA was not correlated with bacterial abundance but was significantly correlated with temperature. Moreover, differences in lipase, α-glucosidase and β-glucosidase activity levels between spring and summer were noted. At the same time, the location of sampling site had a significant influence on aminopeptidase activity. The taxonomic analysis of bacterioplankton communities in the Brda River indicated that, although different numbers of OTUs were recorded in the studied river sections, bacterioplankton biodiversity did not change significantly along the river with distance downstream. Anthropogenically modified river sections were characterized by the dominance of Flavobacterium (Bacterioidetes) and hgcl clade (Actinobacteria) taxa, known for their ability to produce extracellular enzymes. PCoA analysis revealed that the sites located in the lower river course (urban area) had the most similar bacterial community structure (β-diversity). The study provides new insight into the changes in microbial communities along the river and emphasizes the potential impact of anthropogenization on these processes. Full article
