This book was released on 2024-02-07 with total page 179 pages. Available in PDF, EPUB and Kindle. Book excerpt: The majority of global seafood production and mariculture activities take place in marine coastal water bodies, especially in areas of high primary productivity (from microalgae and plankton). This productivity sustains many forms of ecosystem services and promotes carbon dioxide absorption. However, climate change (ocean warming, acidification, oxygen loss, etc.) and anthropogenic disturbances (nutrients intrusion, aquaculture) have influenced the microalgae/plankton community assemblage and shifted it into a highly productive zone, causing a severe impact on the marine ecosystem, such as an increase in Harmful Algal Blooms, dead zone expansions, and coral-algal phase shifts. So far, there is still little knowledge on the mechanisms of microalgae/plankton community response to these changing environmental conditions. Harmful microalgae impair the marine ecosystem through the production of the so-called shellfish toxins, which cause shellfish contamination and poisoning to the vertebrates, including humans. In addition, some microalgae produce fish-killing toxins (ichthyotoxins), causing increasing damage to marine aquaculture. Besides that, the high productivity/bloom of microalgae in the water due to coastal eutrophication from anthropogenic activities is known to induce hypoxic-anoxic conditions causing a severe economic impact on aquaculture.

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 Plankton written by Iain Suthers and published by CSIRO PUBLISHING. This book was released on 2019-04-01 with total page 249 pages. Available in PDF, EPUB and Kindle. Book excerpt: Healthy waterways and oceans are essential for our increasingly urbanised world. Yet monitoring water quality in aquatic environments is a challenge, as it varies from hour to hour due to stormwater and currents. Being at the base of the aquatic food web and present in huge numbers, plankton are strongly influenced by changes in environment and provide an indication of water quality integrated over days and weeks. Plankton are the aquatic version of a canary in a coal mine. They are also vital for our existence, providing not only food for fish, seabirds, seals and sharks, but producing oxygen, cycling nutrients, processing pollutants, and removing carbon dioxide from our atmosphere. This Second Edition of Plankton is a fully updated introduction to the biology, ecology and identification of plankton and their use in monitoring water quality. It includes expanded, illustrated descriptions of all major groups of freshwater, coastal and marine phytoplankton and zooplankton and a new chapter on teaching science using plankton. Best practice methods for plankton sampling and monitoring programs are presented using case studies, along with explanations of how to analyse and interpret sampling data. Plankton is an invaluable reference for teachers and students, environmental managers, ecologists, estuary and catchment management committees, and coastal engineers.
Download or read book Long term Response of Marine Plankton to Climate Change in the North Atlantic Ocean During the Past 24 000 Years written by Tonke Strack and published by . This book was released on 2023 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: This cumulative doctoral thesis aims to comprehensively assess the long-term response of marine plankton biodiversity to climate change, comparable in magnitude to predicted future warming. For this, the fossil record of planktonic foraminifera, prolific marine calcifier, is analysed across the last ice age to the current warm period on global and local scales and compared to changes in reconstructed sea surface temperature (SST). By comparing the results with coccolithophore and dinoflagellate responses, two groups representing different functional groups, it is further assessed whether the response of planktonic foraminifera is representative of marine plankton. Asymmetric range shifts and poleward migrations of planktonic foraminifera assemblages are observed, leading to a surplus of species in the mid-latitudes and the emergence of novel assemblages with the beginning of the current warm period. Deviations between assemblage changes and SST changes during the current warm period are also evident in coccolithophores and dinoflagellates. This suggests the influence of other forcing factors such as ecological interactions in marine plankton responses, especially during periods of lower environmental forcing (i.e., the Holocene). Furthermore, local patterns of biodiversity change revealed potential inaccuracies in the SST reconstruction employed in the study to reflect true SST variations during the current warm period. This doctoral thesis sheds light on the complex dynamics of marine plankton biodiversity in response to climate change. It highlights the need for a critical evaluation of SST reconstructions before applying them to predict biodiversity change or test ecological concepts. Furthermore, while this study offers insights into the response of plankton communities to climate change similar in magnitude to projected future warming, the accelerated pace of modern global warming raises questions about whether these communities will respond similarly.
Download or read book Real time Coastal Observing Systems for Marine Ecosystem Dynamics and Harmful Algal Blooms written by Babin, Marcel and published by UNESCO. 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.

Book excerpt: This report explores the potential for mitigating the impacts of climate change by improved management and protection of marine ecosystems and especially the vegetated coastal habitat, or blue carbon sinks. The objective of this report is to highlight the critical role of the oceans and ocean ecosystems in maintaining our climate and in assisting policy makers to mainstream an oceans agenda into national and international climate change initiatives. While emissions' reductions are currently at the centre of the climate change discussions, the critical role of the oceans and ocean ecosystems has been vastly overlooked.
Download or read book Algal Biorefineries written by Aleš Prokop and published by Springer. This book was released on 2015-10-28 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Algae offer potential to produce renewable chemicals and fuels using solar energy and carbon dioxide from atmosphere or in flue gases while simultaneously reducing the generation of greenhouse gases. Since these can be grown on marginal lands with micronutrients and macronutrients often present in waste streams, algae-based chemicals and fuels do not compete with foods. Still large-scale production of algae-based fuels and chemicals faces considerable technological and economical challenges and it would by necessity require a biorefinery approach wherein all the possible algal components are converted into value-added compounds. The present series on algal biorefineries represents a forum for reporting the state of the art of different technologies as well as the latest advances in this field. The volume II of this series complements the volume I in terms of the current state of the art. Different chapters in this volume address diverse issues ranging from genetically modifies algae to new products to life-cycle analysis of algal products.

Download or read book Ocean Biogeochemistry written by Michael J.R. Fasham and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 324 pages. Available in PDF, EPUB and Kindle. Book excerpt: Oceans account for 50% of the anthropogenic CO2 released into the atmosphere. During the past 15 years an international programme, the Joint Global Ocean Flux Study (JGOFS), has been studying the ocean carbon cycle to quantify and model the biological and physical processes whereby CO2 is pumped from the ocean's surface to the depths of the ocean, where it can remain for hundreds of years. This project is one of the largest multi-disciplinary studies of the oceans ever carried out and this book synthesises the results. It covers all aspects of the topic ranging from air-sea exchange with CO2, the role of physical mixing, the uptake of CO2 by marine algae, the fluxes of carbon and nitrogen through the marine food chain to the subsequent export of carbon to the depths of the ocean. Special emphasis is laid on predicting future climatic change.
