We are pleased to announce a forthcoming Special Issue of Diversity focused on freshwater lake microbial communities. Globally, freshwaters are scarce commodities and make up only 0.009% of the Earth’s total water. Natural freshwaters are found in rivers and lakes, having a unique microbial ecology. Microbial communities (bacteria, archaea, and microbial eukaryotes) significantly contribute to the biodiversity of aquatic ecosystems and play an important role in food webs and biogeochemical cycles. The role bacteria and other microorganisms play in ecosystems and in biogeochemical cycles has been thoroughly investigated. For instance, the concept of the microbial loop is well established in lakes, meaning that microorganisms in the pelagic zone play important roles as links between dissolved organic matter and higher trophic levels. This activity is, for example, contributing to the important role lakes play in the global carbon cycle through consumption and emission of carbon dioxide and thereby in the regulation of the global climate. However, in these studies, microbial communities were mainly tracked using large part measurements of activity and abundance, paying little attention to the role of diversity and the contribution of individual populations and taxa. The structure of microbial communities is affected by interspecies interactions and local physicochemical and regional conditions. Phytoplankton bloom is one of the major factors affecting the composition of bacterial communities. Co-occurrence and correlation patterns can be used to predict positive and negative ecological interactions between various species and environmental parameters in freshwater ecosystems.
Despite methodological developments that have led to an exponential increase in the amount of data over time, we still have only little knowledge of the diversity of freshwater bacteria, and few general patterns in diversity have emerged. Using molecular methods, which enables the study of unculturable microorganisms, new information regarding freshwater microbial ecology has emerged in recent times: there are more phylogenetic groups of bacteria than are observed by cultural methods; there is a unique and distinct bacterial group, which can be termed “typical freshwater bacteria”; marine–freshwater transitional populations exist in coastal waters. The need for further research is exemplified by some findings of bacterial alpha diversity that further indicate that microbial diversity may not always follow the same rules as in larger organisms, challenging some established textbook “truths” regarding what is influencing diversity in general. Much more research is needed for certain conclusions. Future work should also include the identification of the true (active) players and their possible importance for ecosystem functioning. This Special Issue is an exciting opportunity to combine and synthesize recent research on the biodiversity and structure of freshwater microbial communities, as well as patterns of coexistence of bacteria, microbial eukaryotes, and environmental factors.

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. Diversity is an international peer-reviewed open access monthly journal published by MDPI.
Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2600 CHF (Swiss Francs).
