This book was released on 2012 with total page 81 pages. Available in PDF, EPUB and Kindle. Book excerpt: This study determined the effects of selected algal species that commonly occur along the Southern California coast on purple urchin (Strongylocentrotus purpuratus) fertilization and embryo development. Algal blooms occur in Southern California with irregular intensity and timing and are monitored by the Harmful Algae and Red Tide Regional Monitoring Program, which is part of the Southern California Coastal Ocean Observing System (SCCOOS). The Scripps Institution of Oceanography (SIO), on the University of California, San Diego (UCSD) campus, discharges into an Area of Special Biological Significance (ASBS), as designated by the State Water Resources Control Board. As part of the discharge monitoring program, U.S. Environmental Protection Agency toxicity test methods are conducted on samples collected from the outfalls and receiving water twice a year, once during a storm event and once during dry weather. Five marine phytoplankton species were laboratory cultured for testing, including dinoflagellates (Lingulodinium polyedrum, Prorocentrum micans, and Akashiwo sanguinea) and diatoms (Thalassiosira rotula and Thalassiosira psuedonana). A naturally occurring bloom sample collected off of Scripps Pier of A. sanguinea was also used in this study. The hypothesis for this project was that toxic effects to sea urchin egg fertilization and embryo development will be observed at the highest environmentally relevant algal concentrations. Based on available literature, it is further hypothesized that the diatom T. pseudonana will show less of an effect than the dinoflagellates L. polyedrum and A. sanguinea as T. pseudonana is frequently used as a negative control. It is also anticipated that T. rotula, L. polyedrum, and A. sanguinea will have a greater effect than P. micans because of the lower level of biotoxin concentration created by P. micans. Additionally, it was anticipated that there would be an increase in the biotoxin effect after phytoplankton were in seawater overnight at 4 Celsius (oC). Results indicated that the presence through spiking of both laboratory cultured and naturally occurring populations of A. sanguinea in seawater decreased urchin fertilization potential and normal embryo development. The observed effects significantly increased with manual agitation of the algae. This study provides insight into the effects of naturally occurring algal blooms and the potential influence on mandated toxicity testing of the receiving waters in this ASBS.

Book excerpt: This paper provides an extensive review of different aspects of five shellfish-poisoning syndromes (paralytic, diarrhoeic, amnesic, neurologic and azapiracid), as well as one fish-poisoning syndrome (ciguatera fish poisoning), and discusses in detail the causative toxins produced by marine organisms, chemical structures and analytical methods of the toxins, habitat and occurrence of the toxin-producing organisms, case studies and existing regulations. Based on this analysis, risk assessments are carried out for each of the toxins, and recommendations are elaborated to improve the management of these risks in order to reduce the harmful effect of these toxins on public health.

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 460 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 Marine Algal Bloom Characteristics Causes and Climate Change Impacts written by Santosh Kumar Sarkar and published by Springer. This book was released on 2018-05-02 with total page 182 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the marine environment, single-celled, microscopic, plant-like organisms naturally occur in the well-lit surface layer of any body of water. These organisms, referred to as phytoplankton or microalgae, form the base of the food web upon which nearly all other marine organisms depend. Algal bloom is a rapid increase in or accumulation of the population of about 300 species of algae due to excess nutrients (eutrophication), and is of major global interest as it causes reduction in species diversity, abrupt changes in water quality, and discoloration of the water (green, yellow, brown or red) depending on the species of algae and the type of pigments they contain. Dying blooms can also be an environmental concern as when the cells sink and decay, bacteria break down the organic material, which in turn strips oxygen from the water. This microbial oxygen demand at times leads to very low oxygen levels in the bottom waters, harming aquatic life. Documentation of this sporadic high abundance of algae, together with the significant species richness of the diatoms, requires comprehensive studies in the Sundarban coastal environment, which is facing severe degradation due to natural & anthropogenic stressors. In addition, a better understanding of the effects of algal blooms on seafood quality, the complex biological, chemical and physical interactions and subsequent effects on trophodynamics is needed to develop strategies for effective coastal zone management. The book discusses the occurrence of harmful algal blooms (HABs) caused by the dinoflagellates of the genus Alexandrium and Karenia, or diatoms of the genus Pseudo-nitzschia, which have large and varied impacts on marine ecosystems (such as large-scale marine mortality events that have been associated with various types of shellfish poisonings) depending on the species involved, the environment where they are found, and the mechanism by which they exert negative effects. HABs represent a major environmental problem in all regions of the U.S., and their occurrence is on the rise due to increased nutrient pollution. HABs have severe impacts on human health, aquatic ecosystems, and the economy. Such blooms, known colloquially as red tides due to their red or brown hues, are increasing in frequency and magnitude worldwide as a result of changes in oceanic climate, increased coastal eutrophication and enhanced long-distance dispersal in ballast water. As such, the book offers an in-depth account of the complex biological, chemical and physical interactions of the algal blooms (both innocuous and harmful ones). It also discusses the highly topical issue of the impact of global climate change on the frequency and severity of HABs in the context of alterations in temperature, stratification, light and ocean acidification. Focusing on both basic and applied limnology, this book is a reliable and up-to-date reference resource for students, teachers and researchers engaged in the field of coastal research/management at regional and global scales.
