Aquatic ecosystems are currently experiencing unprecedented levels of impact from human activities including over-exploitation of resources, habitat destruction, pollution and the influence of climate change. The impacts of these activities on the microbial ecology of aquatic environments are only now beginning to be defined. One of the many implications of environmental degradation and climate change is the geographical expansion of disease- causing microbes such as those from the Vibrio genus. Elevating sea surface temperatures correlate with increasing Vibrio numbers and disease in marine animals (e.g. corals) and humans. Contamination of aquatic environments with heavy metals and other pollutants affects microbial ecology with downstream effects on biogeochemical cycles and nutrient turnover. Also of importance is the pollution of aquatic environments with antibiotics, resistance genes and the mobile genetic elements that house resistance genes from human and animal waste. Such contaminated environments act as a source of resistance genes long after an antibiotic has ceased being used in the community. Environments contaminated with mobile genetic elements that are adapted to human commensals and pathogens function to capture new resistance genes for potential reintroduction back into clinical environments. This research topic encompasses these diverse topics and describes the affect(s) of human activity on the microbial ecology and function in aquatic environments and, describes methods of restoration and for modelling disturbances.

Microorganisms are a major part of the Earth’s biological diversity. Although a lot of research has been done on microbial diversity, most of it is fragmented. This book creates the need for a unified text to be published, full of information about microbial diversity from highly reputed and impactful sources. Recent Advancements in Microbial Diversity brings a comprehensive understanding of the recent advances in microbial diversity research focused on different bodily systems, such as the gut. Recent Advancements in Microbial Diversity also discusses how the application of advanced sequencing technologies is used to reveal previously unseen microbial diversity and show off its function. Gives insight into microbial diversity in different bodily systems Explains novel approaches to studying microbial diversity Highlights the use of omics to analyze the microbial community and its functional attributes Discusses the techniques used to examine microbial diversity, including their applications and respective strengths and weaknesses

This book discusses how aquatic microbial communities develop interactive metabolic coordination both within and between species to optimize their energetics. It explains that microbial community structuration often includes functional stratification among a multitude of organisms that variously exist either suspended in the water, lodged in sediments, or bound to one another as biofilms on solid surfaces. The authors describe techniques that can be used for preparing and distributing microbiologically safe drinking water, which presents the challenge of successfully removing the pathogenic members of the aquatic microbial community and then safely delivering that water to consumers. Drinking water distribution systems have their own microbial ecology, which we must both understand and control in order to maintain the safety of the water supply. Since studying aquatic microorganisms often entails identifying them, the book also discusses techniques for successfully isolating and cultivating bacteria. As such, it appeals to microbiologists, microbial ecologists and water quality scientists.

Freshwater Microbiology: Perspectives of Bacterial Dynamics in Lake Ecosystems provides a comprehensive and systematic analysis of microbial ecology in lakes. It offers basic information on how well the bacterial community composition varies along the spatio-temporal and trophic gradients along with the evaluation of the bioindicator species of bacteria so as to act as a key to predict the trophic status of lake ecosystems. The book helps to identify the factors of potential importance in structuring the bacterial communities in lakes as it delves into the dynamics and diversity of bacterial community composition in relation to various water quality parameters. It helps to identify the possibility of bioremediation plans and devising future policy decisions, with better conservation and management practices. Provides a comprehensive and systematic analysis of microbial ecology Helps to identify the factors of potential importance in structuring the bacterial community composition Gives insight into the bacterial diversity of freshwater lake ecosystems along with their industrial potential Caters to the needs and aspirations of students and professional researchers

This book provides examples of pollutants, such as accidental oil spills and non-degradable plastic debris, which affect marine organisms of all taxa. Terrestrial runoff washes large amounts of dissolved organic materials from agriculture and industry, toxic heavy metals, pharmaceuticals, and persistent organic pollutants which end up into rivers, coastal habitats, and open waters. While this book is not intended to encyclopaedically list all kinds of pollution, it rather exemplifies the problems by concentrating on a number of serious and prominent recent developments. The chapters in this book also discuss measures to decrease and remove aquatic pollution to mitigate the stress on aquatic organisms. Aquatic ecosystems provide a wide range of ecological and economical services. In addition to providing a large share of the staple diet for a fast growing human population, oceans absorb most of the anthropogenically emitted carbon dioxide and mitigate climate change. As well as rising temperatures and ocean acidification, pollution poses increasing problems for aquatic ecosystems and organisms reducing its functioning and services which are exposed to a plethora of stress factors.

Marine environments are fluid. Microorganisms living in the ocean experience diverse environmental changes over wide spatiotemporal scales. For microorganisms and their communities to survive and function in the ocean, they need to have the capacity to sense, respond to, adapt to and/or withstand periodic and sporadic environmental changes. This eBook collates a variety of recent research reports and theoretical discussions on the ecoenergetic strategies, community structure, biogeochemical and ecosystem functions as well as regulatory processes and mechanisms that marine microorganisms employ in response to environmental gradients and variations.
