Dams or barriers are among the most significant anthropogenic threats to global freshwater ecosystems, although they provide invaluable services for shipping, hydropower generation, flood protection, and storage of drinking and irrigation water. River fragmentations due to dams and barriers lead the aquatic landscape into isolated river sections, resulting in hydromorphological discontinuities along longitudinal or lateral gradients. Fragmented river habitats are unstable. They experience uncertain disturbances in both time and space with random and complex hydrological and environmental processes, such as water flow, particulate matter sedimentation, reservoir regulation, and terrestrial input. The diversity, composition, functionality, and activity of microbial communities are important indicators of river ecosystem functions and services. Yet, river fragmentations are likely to disrupt and reconstruct microbial communities, redirecting the patterns of biogeochemical cycles of biogenic elements. Methodology, such as mathematical models, is still limited to describing and elucidating microbial processes under changing hydrological environments in the fragmented rivers. Thus, how do the riverine microbial communities and ecosystem functions respond to the fragmentation in rivers? This Research Topic represents a collective focus on microbial ecology, functional diversity, and new microbial modeling in fragmented rivers. We wish to present new findings in community assembly mechanisms, biotic interactions, functional diversity, and ecosystem functioning responses to the river fragmentations. New perspectives will also provide us with deep insights into the ecological effects of river fragmentation. This Research Topic aims to present the original research articles and reviews to provide new findings on microbial diversity and ecosystem functioning in fragmented rivers worldwide. We welcome original research, reviews, mini-reviews, opinions, methods, hypotheses and theories, and perspectives. The directions include but are not limited to the following aspects: - The continuum of the microbial community in responses to dams or barriers. - Novel microbial community assembly mechanisms, functional traits, and biotic interactions in fragmented rivers at local, regional, and global scales. - Functional genes, functional groups, and functional diversity in driving biogenic element cycles. - Mathematical modeling in aquatic microbial ecology.

This contributed volume deals with the various aspects of freshwater microbiology including diverse habitats, associated microorganisms, their ecological interactions, and industrial applications. Freshwater ecosystems are dynamic natural resources, providing sources of potable water, food, animal habitats, and recreation. Perspectives of microbial dynamics in freshwater bodies, covered in this title, provide a comprehensive and systematic analysis of microbial ecology in these ecosystems. These microbes are at the hub of biogeochemical cycles (carbon, nitrogen, phosphorus, potassium, and other elements). Moreover, they are an integral part of the aquatic food web and control the quality of freshwater bodies. Chapters in this title also discuss the issue of pollution in freshwater bodies and put forward available strategies for eco-friendly solutions. The book is a perfect documentation of primary and secondary data-based information on the latest research findings, case studies, experiences, and innovations in the field of freshwater microbiology. The book is of great use to students, researchers, and professionals studying aquatic sciences.

This book with 10 chapters (following an Introduction) covers the major questions of forest fragmentation as general questions affecting the world's forest biodiversity, ecosystem function and ecosystem services. These are not merely case studies from particular places in the world, confirming what we already know. Rather, these are carefully selected topics that provide a broad overview of the major questions confronting forest ecologists, conservation biologists and environmental policy makers. Among the key themes throughout the book are whether land sharing or land intensification represents a better way to protect biodiversity, if subsidies from carbon sequestration programmes such as REDD (reducing emissions from deforestation and forest degradation) can provide a permanent solution to forest conservation and how forest fragments will be able to persist during a changing climate. An additional topic is the extent to which government policies can reverse the effects of forest fragmentation and rebuild the forest systems that can protect biodiversity. As such, this book will make excellent reading for graduate students seeking to understand the general topic of forest fragmentation and to discern which are the major questions of current concern. Furthermore, this will provide a valuable reference for environmental policy makers, while conservation biologists and ecologists can use these essays to develop a cutting-edge research agenda.

Global Change Ecology promotes the understanding of how globally important changes in the environment, disrupt all aspects of ecological systems. Especially, the environmental changes that are driven by human influences and natural processes (e.g., climate change, urbanization, biological invasion, and pollution), resulting in biodiversity loss and eco-evolutionary deleterious impacts at the scales of populations, communities, or ecosystems. Alternatively, the recognition of ecological responses can enhance their resilience and resistance to environmental disturbances in different ecological systems. For example, the implications of these environmental threats on biodiversity and ecosystems can boost the interventions of strategies and the development of new techniques. The management solutions developed aim to increase environmental sustainability and mitigate the ecological impacts on biota in the Anthropocene. By collecting multi-disciplinary efforts in the form of primary research articles or perspective reviews, we can comprehensively understand how global change influences the biota and, consequently, construct valuable adaptation strategies. This Research Topic will examine the effects of a variety of environmental stresses on different organisms (e.g., plants, vertebrates, invertebrates, microorganisms) in a range of biomes (e.g., terrestrial, freshwater, and marine systems). In addition, our collection of articles will assemble studies on the ecological and evolutionary responses and influences of organisms, populations, communities, and ecosystems under experimental, modeled, or observed environmental change. These efforts can be devoted to the environmental events and the associated impacts at global and regional scales on a long-term or short-term bases. The scope of our Research Topic includes, but is not limited to, the following interests: • Ecological responses to climate change and extreme weather • Land use change and ecological connectivity • Sustainable agriculture and biodiversity • Urbanization and ecological influences • Ecological impacts of contaminants and pollutants • Ecological changes to biological invasions • Climate-change mitigations and the shifting distribution of species • Mechanisms of eco-evolutionary resilience and resistance • Environmental protection and restoration techniques and policies • Research and datasets for future assessments and modeling • Ecological monitoring through the linkages and networks on long-term or large-scale bases.

This book is about phylogenetic diversity as an approach to reduce biodiversity losses in this period of mass extinction. Chapters in the first section deal with questions such as the way we value phylogenetic diversity among other criteria for biodiversity conservation; the choice of measures; the loss of phylogenetic diversity with extinction; the importance of organisms that are deeply branched in the tree of life, and the role of relict species. The second section is composed by contributions exploring methodological aspects, such as how to deal with abundance, sampling effort, or conflicting trees in analysis of phylogenetic diversity. The last section is devoted to applications, showing how phylogenetic diversity can be integrated in systematic conservation planning, in EDGE and HEDGE evaluations. This wide coverage makes the book a reference for academics, policy makers and stakeholders dealing with biodiversity conservation.
