High-resolution images of phytoplankton cells such as diatoms or desmids, which are useful for monitoring water quality, can now be provided by digital microscopes, facilitating the automated analysis and identification of specimens. Conventional approaches are based on optical microscopy; however, manual image analysis is impractical due to the huge diversity of this group of microalgae and its great morphological plasticity. As such, there is a need for automated recognition techniques for diagnostic tools (e.g. environmental monitoring networks, early warning systems) to improve the management of water resources and decision-making processes. Describing the entire workflow of a bioindicator system, from capture, analysis and identification to the determination of quality indices, this book provides insights into the current state-of-the-art in automatic identification systems in microscopy.
This 2-volume set constitutes the refereed proceedings of the 9th Iberian Conference on Pattern Recognition and Image Analysis, IbPRIA 2019, held in Madrid, Spain, in July 2019. The 99 papers in these volumes were carefully reviewed and selected from 137 submissions. They are organized in topical sections named: Part I: best ranked papers; machine learning; pattern recognition; image processing and representation. Part II: biometrics; handwriting and document analysis; other applications.
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 o...
EURECA-PRO is the global educational core hub and interdisciplinary research and innovation leader in qualitative environmental and social framework development for responsible consumption and production. Through its novel approach, on the one hand, it holistically contributes to the highly topical issue of Sustainable Consumption and Production under the umbrella of Sustainable Development Goal 12, and on the other hand it effectively contributes to the development of the European Higher Education Area complimentary to Sustainable Development Goal 4. In this book readers will find the discussion results among professionals, academics and scientists on responsible consumption and production,...
The enduring changes in the aquatic environment and the increasing influx of contaminants call for novel conceptual and methodological approaches to relating chemical pollution and ecological alterations in ecosystems. This volume highlights the latest advances concerning the sampling, analyses, occurrence, bioavailability, and effects of emerging and priority pollutants in European rivers, the current status of the River Management Plans in Europe, and the applicability of the newly developed techniques for water monitoring purposes. The topics are discussed in the context of the EU Water Framework Directive, evaluating their shortcomings and providing a basis for doing away with them. Linking scientific research and river management practices, this book is an invaluable source of information for environmental chemists, aquatic scientists, ecologists and water managers.
Genuine ecotourism can have many positve impacts, particularly the conservation of biodiversity and cultural heritage and the creation of economic opportunities for local communities. While promoting these, it aims to eleminate negative impacts such as environmental degradation, cultural commoditisation and playground effects. Unfortunately, the concept is broadly misunderstood and its true definition is widely debated. It is often used as a marketing tool, with some operators taking advantage of the ecotourism label to attract more business while behaving in environmentally irresponsible ways. This book considers the important topic of quality control and accreditation in ecotourism, describing the mechanisms that can be implemented to ensure quality in all aspects of the industry, namely protected areas, businesses, producs and tour guides.
Industrial wastewater can contain many toxic pollutants as well as varying concentrations of organic and inorganic matter. These pollutants can be carcinogenic, mutagenic, or hardly biodegradable, which could cause serious human health risks and also affect other aquatic and terrestrial biota as well. Biological treatment techniques for industrial wastewater, including aerobic and anaerobic digestion, are known to be environmentally friendly, clean, and generally superior to other physicochemical techniques. Aerobic and Anaerobic Microbial Treatment of Industrial Wastewater presents the latest information on multiple bioremediation treatment techniques; summarizes the sources, occurrence, and removal of industrial pollutants; and suggests the most appropriate treatment options for different scenarios. Describes the biochemistry of pollutant removal by aerobic and anaerobic digestion. Highlights emerging pollutants as well as resource recovery techniques from contaminated industrial wastewater. Emphasizes the role of both conventional and innovative novel technologies in aerobic and anaerobic microbial bioremediation of pollutants originated from industrial wastewater.
The papers showcase the breadth of discrete geometry through many new methods and results in a variety of topics. Also included are survey articles on some important areas of active research. This volume is aimed at researchers in discrete and convex geometry and researchers who work with abstract polytopes or string C C-groups. It is also aimed at early career mathematicians, including graduate students and postdoctoral fellows, to give them a glimpse of the variety and beauty of these research areas. Topics covered in this volume include: the combinatorics, geometry, and symmetries of convex polytopes; tilings; discrete point sets; the combinatorics of Eulerian posets and interval posets; symmetries of surfaces and maps on surfaces; self-dual polytopes; string C C-groups; hypertopes; and graph coloring.
