This book was released on 2001 with total page 268 pages. Available in PDF, EPUB and Kindle. Book excerpt: One challenge in phytoplankton ecology is to measure species-specific physiological responses to changes in environmental conditions. Of importance are species such as the toxic dinoflagellate Alexandrium fundyense which inhabit coastal regions and are not usually dominant. The aim of this thesis was to identify physiological and behavioral diagnostics of A. fundyense from the Gulf of Maine, and use these indicators to evaluate field populations. Using a surface-specific monoclonal-antibody two methods, flow cytometry and immunomagnetic bead-separation, were developed to identify and separate A. fundyense. Flow-cytometric techniques successfully detected and separated Alexandrium from co-occurring organisms. Using immunomagnetic-separation live A. fundyense cell were separated from spiked field samples and then used to obtain accurate chlorophyll, protein and biomass estimates. Laboratory water columns, nitrogen-(N)-starved batch cultures, and N-limited, semi-continuous cultures, were used to identify indicators of different N-nutritional states. Prolonged N-stress caused dramatic changes intracellular biochemistry, specifically toxin content and composition, however behavioral modifications were not observed. The indicators, specifically toxin ratios of different derivatives, were then used to examine toxin variability in field populations. Toxin compositional changes did occur that were generally consistent with N-stress as the bloom progressed. Overall, these results suggest that these approaches could provide valuable species-specific physiological information.

Available in PDF, EPUB and Kindle. Book excerpt: This volume is a source book of protocols for studying, monitoring and managing harmful marine microalgae. Proliferation of microalgae in marine, brackish or fresh waters can cause massive fish kills, contaminate seafood with toxins and alter ecosystems in ways humans perceive as harmful. About 300 species of microalgae are reported to form mass occurrences, so-called 'blooms', and nearly one-fourth of these species are known to produce toxins.This manual covers the fields of harmful algal sampling, identification, culturing, toxin analysis, toxicology and management.

This book was released on 2008-06-05 with total page 880 pages. Available in PDF, EPUB and Kindle. Book excerpt: The proliferation of harmful phytoplankton in marine ecosystems can cause massive fish kills, contaminate seafood with toxins, impact local and regional economies and dramatically affect ecological balance. Real-time observations are essential for effective short-term operational forecasting, but observation and modelling systems are still being developed. This volume provides guidance for developing real-time and near real-time sensing systems for observing and predicting plankton dynamics, including harmful algal blooms, in coastal waters. The underlying theory is explained and current trends in research and monitoring are discussed.Topics covered include: coastal ecosystems and dynamics of harmful algal blooms; theory and practical applications of in situ and remotely sensed optical detection of microalgal distributions and composition; theory and practical applications of in situ biological and chemical sensors for targeted species and toxin detection; integrated observing systems and platforms for detection; diagnostic and predictive modelling of ecosystems and harmful algal blooms, including data assimilation techniques; observational needs for the public and government; and future directions for research and operations.

Download or read book Global Ecology and Oceanography of Harmful Algal Blooms written by Patricia M. Glibert and published by Springer. This book was released on 2018-04-26 with total page 461 pages. Available in PDF, EPUB and Kindle. Book excerpt: Harmful algal blooms (HABs) - blooms that cause fish kills, contaminate seafood with toxins, or cause human or ecological health impacts and harm to local economies - are occurring more often, in more places and lasting longer than in past decades. This expansion is primarily the result of human activities, through increased nutrient inputs and various aspects of climate change. The Global Ecology and Oceanography of Harmful Algal Blooms (GEOHAB) programme promoted international collaboration to understand HAB population dynamics in various oceanographic regimes and to improve the prediction of HABs. This volume introduces readers to the overarching framework of the GEOHAB programme, factors contributing to the global expansion of harmful algal blooms, the complexities of HABs in different habitats, and the forward-looking issues to be tackled by the next generation of GEOHAB, GlobalHAB. The programme brought together an international team of contributing scientists and ecosystem managers, and its outcomes will greatly benefit the international research community.

Download or read book Eutrophication causes consequences and control written by Abid A. Ansari and published by Springer Science & Business Media. This book was released on 2010-10-17 with total page 402 pages. Available in PDF, EPUB and Kindle. Book excerpt: Eutrophication continues to be a major global challenge to water quality scientists. The global demand on water resources due to population increases, economic development, and emerging energy development schemes has created new environmental challenges to global sustainability. Eutrophication, causes, consequences, and control provides a current account of many important aspects of the processes of natural and accelerated eutrophication in major aquatic ecosystems around the world. The connections between accelerated eutrophication and climate change, chemical contamination of surface waters, and major environmental and ecological impacts on aquatic ecosystems are discussed. Water quality changes typical of eutrophication events in major climate zones including temperate, tropical, subtropical, and arid regions are included along with current approaches to treat and control increased eutrophication around the world. The book provides many useful new insights to address the challenges of global increases in eutrophication and the increasing threats to biodiversity and water quality.
Download or read book Marine and Freshwater Toxins written by P. Gopalakrishnakone and published by Springer. This book was released on 2016-03-14 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: In recent years, the field of Toxinology has expanded substantially. On the one hand it studies venomous animals, plants and micro organisms in detail to understand their mode of action on targets. While on the other, it explores the biochemical composition, genomics and proteomics of toxins and venoms to understand their three interaction with life forms (especially humans), development of antidotes and exploring their pharmacological potential. Therefore, Toxinology has deep linkages with biochemistry, molecular biology, anatomy and pharmacology. In addition, there is a fast developing applied subfield, clinical toxinology, which deals with understanding and managing medical effects of toxins on human body. Given the huge impact of toxin-based deaths globally, and the potential of venom in generation of drugs for so-far incurable diseases (for example, Diabetes, Chronic Pain), the continued research and growth of the field is imminent. This has led to the growth of research in the area and the consequent scholarly output by way of publications in journals and books. Despite this ever growing body of literature within biomedical sciences, there is still no all-inclusive reference work available that collects all of the important biochemical, biomedical and clinical insights relating to Toxinology. The Handbook of Toxinology aims to address this gap and cover the field of Toxinology comprehensively.
