Download or read book Analysis of Toxic and Non toxic Alexandrium Dinophyceae Species Using Ribosomal RNA Gene Sequences written by Christopher Alan Scholin and published by . This book was released on 1993 with total page 602 pages. Available in PDF, EPUB and Kindle. Book excerpt: Sequences of small subunit (Ss) and large subunit (Ls) ribosomal RNA genes (rDNA) from the marine dinoflagellates Alexandrium tamarense, A. catenella, A. fundyense, A. affine, A. minutum, A. lusitanicum and A. andersoni were compared to assess the organisms' relationships. Cultures represent isolates from North America, Western Europe, Thailand, Japan, Australia and the ballast water of several cargo vessels, and include both toxic and non-toxic strains. An emphasis was placed on the A. tamarense/catenella/fundyense "species complex," a group of morphotypically-similar organisms found in many regions of the world. Two distinct SsrRNA genes, termed the "A gene" and the "B gene," were found in a toxic A. fundyense isolated from eastern North America. The B gene is considered to be a pseudogene. A restriction fragment length polymorphism (RFLP) assay developed to detect the A and B genes revealed five distinct groups of Alexandrium isolates. Three subdivide the A. tamarense/catenella/fundyense complex, but do not correlate with morphospecies designations. The two remaining groups are associated with cultures that clearly differ morphologically from the A. tamarense/ catenella/fundyense group: the fourth group consists of A. affine isolates, and the fifth group is represented by A. minutum, A.lusitanicum and A. andersoni. The B gene was only found in A. tamarense/catenella/ fundyense, but not in all members of this species complex. The B gene is not uniformly distributed among global populations of Alexandrium. All A. tamarense/catenella/fundyense isolates from North America harbor this gene, but it has also been found in some A. tamarense from scattered locations in Japan, as well as in A. tamarense from the ballast water of one cargo vessel which was on a defined run from Japan to Australia. The B gene may be endemic to North American populations of A. tamarense/catenella/fundyense. It is possible that in the recent past North American A. tamarense were introduced to Japanese waters, and cysts of these organisms have been transported from Japan to Australia. A subset of isolates examined using the the RFLP assay were also compared by cloning and sequencing a fragment of their LsrDNA. Eight major classes of LsrDNA sequences, termed "ribotypes," were identified. Five ribotypes subdivide members of the A. tamarense/catenella!fundyense complex; all isolates containing the B gene cluster as one ribotype. The three remaining ribotypes are typified by: 1) A. affine; 2) A. minutum and A. lusitanicum; and, 3) A. andersoni. LsrDNAs from A. minutum and A. lusitanicum are indistinguishable. A. minutum!lusitanicum/andersoni may represent another Alexandrium species complex, analogous to the A. tamarense/catenella/fundyense group. An organisms' ability to produce toxin appears to be correlated with its LsrDNA phylogenetic lineage. Ribotypes ascribed by the LsrDNA sequences are in complete agreement with, and offer a finer-scale resolution of, groups defined by SsrDNA restriction patterns. The SsrDNA RFLP groups and LsrDNA ribotypes are useful species- and population-specific markers. Alexandrium tamarense/catenella/fundyense exist as geneticallydistinct "strains" (populations), not three genetically-distinct species: representatives collected from the same geographic region appear the most similar, regardless of morphotype, whereas those from geographicallyseparated populations are more divergent even when the same morphospecies are compared. Contrary to this general pattern, A. tamarense/catenella from Japan were found to be exceptionally heterogeneous. Ballast water samples show that viable cysts (resting spores) of toxigenic A. tamarense/catenella are being discharged into Australian ports from multiple, genetically-distinct source populations. The rDNA sequences were also used to test theories accounting for the evolution and global dispersal of A. tamarense/catenella/fundyense. Results suggest a monophyletic radiation of these organisms from a common ancestor that included, or gave rise to, multiple morphotypes. Populations appear to have diverged as a result of vicariance (geographic isolation). The co-occurrence of genetically-distinct strains of these organisms is an indication of dispersal. An example of this is seen in Japan where an introduction of North American A. tamarense appears likely. Determining the timing of dispersal events is problematic if based strictly on rDNA sequence similarities, since these molecules undergo change on a scale of millions of years

Download or read book Joint FAO IOC IAEA technical guidance for the implementation of early warning systems for harmful algal blooms written by Food and Agriculture Organization of the United Nations and published by Food & Agriculture Org.. This book was released on 2023-03-16 with total page 224 pages. Available in PDF, EPUB and Kindle. Book excerpt: Globally, there are 3 400 to 4 000 described species of marine microalgae but only 1 to 2 percent are considered to be harmful. Harmful algal blooms (HABs) have significant impacts on food safety and security through contamination or mass mortalities of aquatic organisms. The impacts and mass mortalities of marine species caused by harmful algae are not new and have been recorded for decades. However, there is growing concern that these events will increase due to accelerating global warming, climate change and anthropogenic activities. Indeed, if not properly controlled, aquatic products contaminated with HAB biotoxins are responsible for potentially deadly foodborne diseases and when rapidly growing, HAB consequences include reduced dissolved oxygen in the ocean, dead zones, and mass mortalities of aquatic organisms. Improving HAB forecasting is an opportunity to develop early warning systems for HAB events such as food contamination, mass mortalities, or foodborne diseases. Surveillance systems have been developed to monitor HABs in many countries; however, the lead-time or the type of data (i.e. identification at the species-level, determination of toxicity) may not be sufficient to take effective action for food safety management measures or other reasons, such as transfer of aquaculture products to other areas. Having early warning systems could help mitigate the impact of HABs and reduce the occurrence of HAB events. The Joint FAO-IOC-IAEA technical guidance for the implementation of early warning systems (EWS) for HABs will guide competent authorities and relevant institutions involved in consumer protection or environmental monitoring to implement early warning systems for HABs present in their areas (marine and brackish waters), specifically those affecting food safety or food security (benthic HABs, fish-killing HABs, pelagic toxic HABs, and cyanobacteria HABs). The guidance provides a roadmap for stakeholders on how to improve or implement an EWS for HABs and biotoxins, where appropriate. It is important to note that not all countries and institutions can implement the same level of EWS for HABs, and this guidance is intended mainly for those who seek to broaden existing early warning systems, or who are just beginning to consider putting a system in place.

Available in PDF, EPUB and Kindle. Book excerpt: Eutrophication in the transitional marine coastal waters has increased dramatically in many parts of the world, and this evolution has shifted attention to the anthropogenic factor. The problem has become the theme of many conferences and workshops, as well as being given priority in international organizations. This volume has been brought about by the desire to assess both our scientific understanding as well as the means and technologies available to combat the problem of marine coastal eutrophication. It discusses the results of research and surveillance programmes carried out in the last decades, confronting these results with experience gained elsewhere, and reviewing current proposals of what can be done about the problem. This volume will be invaluable to environmental scientists and marine ecologists, as well as to those who wish to resolve the many large-scale environmental problems, specifically marine eutrophication and marine pollution in general.

Download or read book Bioluminescent Marine Plankton written by Ramasamy Santhanam and published by Bentham Science Publishers. This book was released on 2022-06-16 with total page 264 pages. Available in PDF, EPUB and Kindle. Book excerpt: Bioluminescence, the “cold living light” or the “cold fire of the sea,” is extremely common in all oceans at all depths. However, this phenomenon is nearly absent in freshwater, with the exception of a freshwater limpet. More than 75% of deep-sea creatures have been reported to produce their own light. The luminescent marine plankton such as dinoflagellate, radiolarians, jellyfish, comb jellies, annelids, copepods, ostracods, mysids, amphipods, euphausiids, and tunicates form an important component in the marine food chain. Research on luminescent marine plankton is gaining momentum owing to its importance in life science research and medicine. The glowing Green Fluorescent Protein (GFP) extracted from the North Pacific jellyfish, Aqueorea victoria (for which the Japanese biologist, Osamu Shimonmura won the Nobel Prize in Chemistry in 2008) has helped shed light on key processes such as the spread of cancer, the development of brain cells, the growth of bacteria, damage to cells by Alzheimer's disease, and the development of insulin-producing cells in the pancreas. Therefore, it is difficult to underscore the importance of bioluminescence and the organisms associated with this phenomenon. Bioluminescent Marine Plankton is a unique reference that attempts to provide answers to questions about bioluminescence. The first of its kind, this book attempts to answer questions on the subject with a focus on planktonic organisms. 12 chapters provide information about the chemistry of bioluminescence, types of bioluminescent displays, distribution of bioluminescence among marine plankton, ecological functions and utility of planktonic bioluminescence. Chapters are dedicated to the biology and ecology of specific groups of plankton that span about 200 luminescent marine species. The detailed book is an essential compendium on marine plankton for a broad range of readers who want to learn about bioluminescent plankton. A list of detailed references is also provided for the benefit of teachers, students, researchers and enthusiasts interested in marine biology, aquaculture, and environmental sciences.
