Download or read book The microbial ferrous wheel iron cycling in terrestrial freshwater and marine environments written by David Emerson and published by Frontiers E-books. This book was released on with total page 217 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the past 15 years, there has been steady growth in work relating to the microbial iron cycle. It is now well established that in anaerobic environments coupling of organic matter utilization to Fe reduction is a major pathway for anaerobic respiration. In iron-rich circumneutral environments that exist at oxic-anoxic boundaries, significant progress has been made in demonstrating that unique groups of microbes can grow either aerobically or anaerobically using Fe as a primary energy source. Likewise, in high iron acidic environments, progress has been made in the study of communities of microbes that oxidize iron, and in understanding the details of how certain of these organisms gain energy from Fe-oxidation. On the iron scarcity side, it is now appreciated that in large areas of the open ocean Fe is a key limiting nutrient; thus, a great deal of research is going into understanding the strategies microbial cells, principally phytoplankton, use to acquire iron, and how the iron cycle may impact other nutrient cycles. Finally, due to its abundance, iron has played an important role in the evolution of Earth’s primary biogeochemical cycles through time. The aim of this Research Topic is to gather contributions from scientists working in diverse disciplines who have common interests in iron cycling at the process level, and at the organismal level, both from the perspective of Fe as an energy source, or as a limiting nutrient for primary productivity in the ocean. The range of disciplines may include: geomicrobiologists, microbial ecologists, microbial physiologists, biological oceanographers, and biogeochemists. Articles can be original research, techniques, reviews, or synthesis papers. An overarching goal is to demonstrate the environmental breadth of the iron cycle, and foster understanding between different scientific communities who may not always be aware of one another’s work.
Download or read book Understanding Marine Biodiversity written by Committee on Biological Diversity in Marine Systems and published by National Academies Press. This book was released on 1995-03-10 with total page 129 pages. Available in PDF, EPUB and Kindle. Book excerpt: The diversity of marine life is being affected dramatically by fishery operations, chemical pollution and eutrophication, alteration of physical habitat, exotic species invasion, and effects of other human activities. Effective solutions will require an expanded understanding of the patterns and processes that control the diversity of life in the sea. Understanding Marine Biodiverity outlines the current state of our knowledge, and propose research agenda on marine biological diversity. This agenda represents a fundamental change in studying the ocean--emphasizing regional research across a range of space and time scales, enhancing the interface between taxonomy and ecology, and linking oceanographic and ecological approaches. Highlighted with examples and brief case studies, this volume illustrates the depth and breadth of undescribed marine biodiversity, explores critical environmental issues, advocates the use of regionally defined model systems, and identifies a series of key biodiversity research questions. The authors examine the utility of various research approaches--theory and modeling, retrospective analysis, integration of biotic and oceanographic surveys--and review recent advances in molecular genetics, instrumentation, and sampling techniques applicable to the research agenda. Throughout the book the critical role of taxonomy is emphasized. Informative to the scientist and accessible to the policymaker, Understanding Marine Biodiversity will be of specific interest to marine biologists, ecologists, oceanographers, and research administrators, and to government agencies responsible for utilizing, managing, and protecting the oceans.

Download or read book Progress in Ecological Stoichiometry written by Dedmer B. Van de Waal and published by Frontiers Media SA. This book was released on 2018 with total page 382 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ecological stoichiometry concerns the way that the elemental composition of organisms shapes their ecology. It deals with the balance or imbalance of elemental ratios and how that affects organism growth, nutrient cycling, and the interactions with the biotic and abiotic worlds. The elemental composition of organisms is a set of constraints through which all the Earth’s biogeochemical cycles must pass. All organisms consume nutrients and acquire compounds from the environment proportional to their needs. Organismal elemental needs are determined in turn by the energy required to live and grow, the physical and chemical constraints of their environment, and their requirements for relatively large polymeric biomolecules such as RNA, DNA, lipids, and proteins, as well as for structural needs including stems, bones, shells, etc. These materials together constitute most of the biomass of living organisms. Although there may be little variability in elemental ratios of many of these biomolecules, changing the proportions of different biomolecules can have important effects on organismal elemental composition. Consequently, the variation in elemental composition both within and across organisms can be tremendous, which has important implications for Earth’s biogeochemical cycles. It has been over a decade since the publication of Sterner and Elser’s book, Ecological Stoichiometry (2002). In the intervening years, hundreds of papers on stoichiometric topics ranging from evolution and regulation of nutrient content in organisms, to the role of stoichiometry in populations, communities, ecosystems and global biogeochemical dynamics have been published. Here, we present a collection of contributions from the broad scientific community to highlight recent insights in the field of Ecological Stoichiometry.
Download or read book Microbial Role in the Carbon Cycle in Tropical Inland Aquatic Ecosystems written by André Megali Amado and published by Frontiers Media SA. This book was released on 2017-03-15 with total page 146 pages. Available in PDF, EPUB and Kindle. Book excerpt: Aquatic microorganisms are tidily related to the carbon cycle in aquatic systems, especially in respect to its accumulation and emission to atmosphere. In one hand, the autotrophs are responsible for the carbon input to the ecosystems and trophic chain. On the other hand, the heterotrophs traditionally play a role in the carbon mineralization and, since microbial loop theory, may play a role to carbon flow through the organisms. However, it is not yet clear how the heterotrophs contribute to carbon retention and emission especially from tropical aquatic ecosystems. Most of the studies evaluating the role of microbes to carbon cycle in inland waters were performed in high latitudes and only a few studies in the tropical area. In the prospective of global changes where the warm tropical lakes and rivers become even warmer, it is important to understand how microorganisms behave and interact with carbon cycle in the Earth region with highest temperature and light availability. This research topic documented microbial responses to natural latitudinal gradients, spatial within and between ecosystems gradients, temporal approaches and temperature and nutrient manipulations in the water and in the sediment.
Download or read book The Responses of Marine Microorganisms Communities and Ecofunctions to Environmental Gradients written by Stefan M. Sievert and published by Frontiers Media SA. This book was released on 2019-04-05 with total page 295 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Provides an integrated new approach to understanding and managing the ocean Shows how biological diversity is the heart of functioning ecosystems Spans genes to earth systems, surface to seafloor, and estuary to ocean gyre Links species composition, trait distribution, and other ecological structures to the functioning of ecosystems Explains how fishing, fossil fuel combustion, industrial fertilizer use, and other human impacts are transforming the Anthropocene ocean An essential textbook for students and an invaluable resource for practitioners
Download or read book Systems Biology of Marine Ecosystems written by Manoj Kumar and published by Springer. This book was released on 2017-10-17 with total page 355 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book describes the latest advances in systems biology in four plant-based marine ecosystems: seaweeds, seagrasses, microalgae, and corals. Marine organisms that inhabit the oceanic environment experience a diverse range of environmental fluctuations, anthropogenic stress, and threats from invasive species and pathogens. System biology integrates physiology, genomics, transcriptomics, proteomics, and metabolomics into numerical models and is emerging as an important approach to elucidate the functional adaptations of marine organisms to adverse environmental conditions. This book focuses on how ecophysiology, omics platforms, their integration (a systems biology perspective), and next generation sequencing tools are being used to address the stress response of marine seaweeds, seagrasses, corals, marine microbe diversity, and micro-and macroalgae/corals-bacterial interactions to global climate change and anthropogenic activities. The contents of the book are of special interest to graduate and postgraduate marine biology students and marine biology researchers, particularly those interested in marine ecology, stress physiology of marine macrophytes/corals/phytoplankton, and environmental microbiology. This book would also be of interest to marine engineers engaged in the management and conservation of our valuable marine resources.

Download or read book Integrating Conservation Biology and Paleobiology to Manage Biodiversity and Ecosystems in a Changing World written by G. Lynn Wingard and published by Frontiers Media SA. This book was released on with total page 349 pages. Available in PDF, EPUB and Kindle. Book excerpt: Policy makers and resource managers must make decisions that affect the resilience and sustainability of natural resources, including biodiversity and ecosystem services. However, these decisions are often based on evidence or theory derived from highly altered systems and over short time periods of low-magnitude environmental and climatic change. Because natural systems change and evolve across multiple timescales from instantaneous to millennial, long-term understanding of how past life has responded to perturbations can inform resource managers. By using these natural laboratories of the past, conservation paleobiology and paleoecology provide the framework necessary to anticipate and plan for future changes. The goal of this Research Topic is to heighten awareness among conservation and restoration practitioners to the value and applications of long-term perspectives provided by conservation paleobiology and paleoecology. Most conservation studies focus on systems already impacted by anthropogenic change; these studies would benefit from paleontological data through expanded temporal scales, identification of baselines, and an understanding of how organisms have responded to past changes. However, resource management decisions rarely include input from paleontologists, and paleoecological research is rarely incorporated into conservation decision-making. We seek to bridge this research-implementation gap by highlighting the application of paleoecological data to issues such as biodiversity dynamics, extinction risks, and resilience to perturbations, among other topics. We hope to foster new cross-disciplinary synergies by encouraging conservation scientists and managers to collaborate with paleontologists to improve conservation decision-making and by increasing awareness among paleontologists to the needs of the resource management community. This Research Topic will provide a forum for both the paleontological and resource management communities to exchange ideas that will enhance restoration and conservation decision-making. We invite papers on conceptual advances, reviews of specific topics to guide efforts in research or practice, case studies of successful applications, articles describing datasets with applied value, and perspective papers summarizing a body of paleontological research with relevance to the resource management community. Topics can include but are not limited to: • Responses of species, communities, and ecosystems to perturbations • Strategies to achieve the direct integration of paleobiology and paleoecology into on-ground resource management • Identifying baselines and reference conditions • Increasing the robustness of forecasting models through the incorporation of paleontological data • Identifying key species, interactions, and other phenomena as indicators of impending change • New methodologies, analytical tools, and/or proxies in the application of paleontological data to conservation and restoration practice Lynn Wingard, Damien Fordham, and Greg Dietl have no conflicts of interest. Chris Schneider has a potential conflict of interest where manuscripts pertain to stakeholders in the petroleum industry, as she is an independent contractor in the Alberta Oil Sands mining area.

This book was released on 2015-01-22 with total page 185 pages. Available in PDF, EPUB and Kindle. Book excerpt: The causes and consequences of differences in microbial community structure, defined here as the relative proportions of rare and abundant organisms within a community, are poorly understood. Articles in “The Causes and Consequences of Microbial Community Structure”, use empirical or modeling approaches as well as literature reviews to enrich our mechanistic understanding of the controls over the relationship between community structure and ecosystem processes. Specifically, authors address the role of trait distributions and tradeoffs, species-species interactions, evolutionary dynamics, community assembly processes and physical controls in affecting ‘who’s there’ and ‘what they are doing.’
