Book excerpt: Algae are an important component of aquatic benthic ecosystems because they reflect the health of their environment through their density, abundance, and diversity. This comprehensive and authoritative text is divided into three sections to offer complete coverage of the discussion in this field. The first section introduces the locations of benthic algae in different ecosystems, like streams, large rivers, lakes, and other aquatic habitats. The second section is devoted to the various factors, both biotic and abiotic, that affect benthic freshwater algae. The final section of the book focuses on the role played by algae in a variety of complex freshwater ecosystems. As concern over environmental health escalates, the keystone and pivotal role played by algae is becoming more apparent. This volume in the Aquatic Ecology Series represents an important compilation of the latest research on the crucial niche occupied by algae in aquatic ecosystems. Presents algae as the important player in relation to environmental health Prepared by leading authorities in the field Includes comprehensive treatment of the functions of benthic algae as well as the factors that affect these important aquatic organisms Acts as an important reference for anyone interested in understanding and managing freshwater ecosystems

Download or read book The Drava River written by Dénes Lóczy and published by Springer. This book was released on 2018-08-24 with total page 399 pages. Available in PDF, EPUB and Kindle. Book excerpt: This monograph summarizes the environmental issues concerning the channel and the floodplain of the Drava River. It describes the diverse forms of human impact (river regulation, damming and reservoirs, dredging etc.) and the environmental changes of hydrological regime, sediment transport, biodiversity etc. involved. The transboundary nature of the river is emphasized and the resulting problems are outlined. Special attention is devoted to the evolution and present condition of the floodplain (drainage pattern, oxbow lakes and their vegetation). The possible solutions to environmental problems are illustrated by a review of ongoing and planned rehabilitation measures. The book is amply illustrated with maps, cross/sections, diagrams and photographs. The international team of authors (representing all countries crossed by the Drava River: Austria, Slovenia, Croatia and Hungary) approach the topic from different aspects. Thus, the reader is provided with a comprehensive picture of this, up until now, little studied European river.

A final section explores diatom use in other fields of study such as forensics, oil and gas exploration, nanotechnology, and archaeology. Sixteen new chapters have been added since the first edition, including introductory chapters on diatom biology and the numerical approaches used by diatomists. The extensive glossary has also been expanded and now includes over 1,000 detailed entries, which will help non-specialists to use the book effectively.
Download or read book Competition and Coexistence written by Ulrich Sommer and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 232 pages. Available in PDF, EPUB and Kindle. Book excerpt: The question "Why are there so many species?" has puzzled ecologist for a long time. Initially, an academic question, it has gained practical interest by the recent awareness of global biodiversity loss. Species diversity in local ecosystems has always been discussed in relation to the problem of competi tive exclusion and the apparent contradiction between the competitive exclu sion principle and the overwhelming richness of species found in nature. Competition as a mechanism structuring ecological communities has never been uncontroversial. Not only its importance but even its existence have been debated. On the one extreme, some ecologists have taken competi tion for granted and have used it as an explanation by default if the distribu tion of a species was more restricted than could be explained by physiology and dispersal history. For decades, competition has been a core mechanism behind popular concepts like ecological niche, succession, limiting similarity, and character displacement, among others. For some, competition has almost become synonymous with the Darwinian "struggle for existence", although simple plausibility should tell us that organisms have to struggle against much more than competitors, e.g. predators, parasites, pathogens, and envi ronmental harshness.

Book excerpt: The problems related to the process of industrialisation such as biodiversity depletion, climate change and a worsening of health and living conditions, especially but not only in developing countries, intensify. Therefore, there is an increasing need to search for integrated solutions to make development more sustainable. The United Nations has acknowledged the problem and approved the “2030 Agenda for Sustainable Development”. On 1st January 2016, the 17 Sustainable Development Goals (SDGs) of the Agenda officially came into force. These goals cover the three dimensions of sustainable development: economic growth, social inclusion and environmental protection. The Encyclopedia of the UN Sustainable Development Goals comprehensively addresses the SDGs in an integrated way. It encompasses 17 volumes, each one devoted to one of the 17 SDGs. This volume is dedicated to SDG 14 “Conserve and sustainably use the oceans, seas and marine resources for sustainable development". Marine and coastal bio-resources, play an essential role in human well-being and social and economic development. This volume addresses this sustainability challenge providing the description of a range of terms, which allows a better understanding and fosters knowledge about it. Concretely, the defined targets are: Prevent and significantly reduce marine pollution of all kinds, in particular from land-based activities, including marine debris and nutrient pollution Sustainably manage and protect marine and coastal ecosystems to avoid significant adverse impacts, including by strengthening their resilience, and take action for their restoration in order to achieve healthy and productive oceans Minimize and address the impacts of ocean acidification, including through enhanced scientific cooperation at all levels Effectively regulate harvesting and end overfishing, illegal, unreported and unregulated fishing and destructive fishing practices and implement science-based management plans, in order to restore fish stocks in the shortest time feasible, at least to levels that can produce maximum sustainable yield as determined by their biological characteristics Conserve at least 10 per cent of coastal and marine areas, consistent with national and international law and based on the best available scientific information Prohibit certain forms of fisheries subsidies which contribute to overcapacity and overfishing, eliminate subsidies that contribute to illegal, unreported and unregulated fishing and refrain from introducing new such subsidies, recognizing that appropriate and effective special and differential treatment for developing and least developed countries should be an integral part of the World Trade Organization fisheries subsidies negotiation 16 Increase the economic benefits to small island developing states and least developed countries from the sustainable use of marine resources, including through sustainable management of fisheries, aquaculture and tourism Increase scientific knowledge, develop research capacity and transfer marine technology, taking into account the Intergovernmental Oceanographic Commission Criteria and Guidelines on the Transfer of Marine Technology, in order to improve ocean health and to enhance the contribution of marine biodiversity to the development of developing countries, in particular small island developing states and least developed countries Provide access for small-scale artisanal fishers to marine resources and markets Enhance the conservation and sustainable use of oceans and their resources by implementing international law as reflected in the United Nations Convention on the Law of the Sea, which provides the legal framework for the conservation and sustainable use of oceans and their resources, as recalled in paragraph 158 of “The future we want” Editorial Board Ulisses M.

Download or read book Diatom Ecology written by Nora I. Maidana and published by John Wiley & Sons. This book was released on 2024-10-08 with total page 467 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book offers a comprehensive, unique and up-to-date exploration of diatom ecology spanning from fundamental molecular aspects to the intricate dynamics of metacommunities. In recent years there has been a considerable increase in the amount of research devoted to diatom ecology, with a wide spectrum of approaches. This large amount of information, published in many different journals and books, makes it very difficult to keep up to date, both for the trained researcher and for students. Eduardo A. Morales (d. May 2023) had the original idea to assemble chapters on various subjects within diatom ecology. The questions he posed to potential contributors framed the current book consisting of 12 chapters. Are diatoms suitable tools for ecological restoration? What would be the features that make them reliable in this context? What makes diatoms ecologically successful? In an ecological sense, why is there such variability in diatom reproductive strategies and why are they worth considering? What do new approaches in ecological synthesis provide to diatom ecology, biogeography and metacommunities? Are all diatoms widely spread and each species uniquely characterized by its own, unaltered phenotype? Can we really make any ecological consideration without knowing (with a high degree of certainty) the identity of taxa? Are urban ecosystems important repositories of biodiversity? What are the benefits and the progress in diatom ecology made by the diatom guild perspective? Why, how and when are soil diatoms used in bioindication and what are the benefits of such an approach? Are diatoms bona fide indicators of climate change? Are diatom communities in temporary rivers important for these lotic ecosystems as they are subjected to the effects of climate change? Do diatoms in peatlands behave differently from their terrestrial and aquatic (rivers, lakes, others) counterparts? Audience The book is intended primarily for professionals in the fields of diatom research, algal research (phycology), organismal, population and community ecology, limnology, microbiology, organismal biology, paleoecology and paleolimnology. The book will also serve as a reference for graduate students seeking guidance on terminology, techniques, and current methods in diatom research.

Download or read book Ocean Acidification written by National Research Council and published by National Academies Press. This book was released on 2010-09-14 with total page 200 pages. Available in PDF, EPUB and Kindle. Book excerpt: The ocean has absorbed a significant portion of all human-made carbon dioxide emissions. This benefits human society by moderating the rate of climate change, but also causes unprecedented changes to ocean chemistry. Carbon dioxide taken up by the ocean decreases the pH of the water and leads to a suite of chemical changes collectively known as ocean acidification. The long term consequences of ocean acidification are not known, but are expected to result in changes to many ecosystems and the services they provide to society. Ocean Acidification: A National Strategy to Meet the Challenges of a Changing Ocean reviews the current state of knowledge, explores gaps in understanding, and identifies several key findings. Like climate change, ocean acidification is a growing global problem that will intensify with continued CO2 emissions and has the potential to change marine ecosystems and affect benefits to society. The federal government has taken positive initial steps by developing a national ocean acidification program, but more information is needed to fully understand and address the threat that ocean acidification may pose to marine ecosystems and the services they provide. In addition, a global observation network of chemical and biological sensors is needed to monitor changes in ocean conditions attributable to acidification.
