The Response of Microalgae and Plankton to Climate Change and Human Activities by Zhaohe Luo,Yanpei Zhuang,Kieng Soon Hii,Hala F. Mohamed Pdf

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.

Changing Plankton Communities: Causes, Effects and Consequences by Kristian Spilling,Letizia Tedesco,Riina Klais,Kalle Olli Pdf

Marine ecosystems are changing at an unprecedented rate. In addition to the direct effects of e.g. warming surface temperatures, the environmental changes also cause shifts in plankton communities. Plankton makes up the base of the marine food web and plays a pivotal role in global biogeochemical cycles. Any shifts in the plankton community composition could have drastic consequences for marine ecosystem functioning. This Research Topic focuses on causes, effects and consequences of such shifts in the plankton community structure.

Marine Algal Bloom: Characteristics, Causes and Climate Change Impacts by Santosh Kumar Sarkar Pdf

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.

Phytoplankton Whispering: An Introduction to the Physiology and Ecology of Microalgae by Patricia M. Glibert Pdf

Phytoplankton, or algae, are the engines of the Earth. They form the base of the aquatic food web and, although microscopic, they produce 50% of the oxygen in the air. Many of our ideas of what makes these cells “tick” come from ideas developed decades ago. But, lakes and oceans are changing- and so, too are phytoplankton. Our understanding has to change accordingly. Nutrient pollution is a major problem worldwide, and climate is changing, altering temperature, CO2 and pH, as well as the physics that control water stratification. All of these factors control which species of phytoplankton may grow well at any particular time. While algae grow in all types of aquatic systems, not all algae are favorable for the production of fish and other food resources. The prevalence of harmful algal blooms (HABs) has increased. At the core of this effort is a drive to understand–and to convey to researchers, students and managers–what kinds of phytoplankton are likely to thrive as conditions change and why this matters. There has not yet been a synthetic summary that unravels the mysteries of phytoplankton in a modern world. This book aims to provide such a resource.

Plankton Ecology of the Southwestern Atlantic by Mónica S. Hoffmeyer,Marina E. Sabatini,Frederico P. Brandini,Danilo L. Calliari,Norma H. Santinelli Pdf

This book integrates a variety of issues such as regional settings of productivity and nutrient cycling; plankton of coastal and shelf systems; plankton, climate change and human-induced changes; harmful algae and their impacts; and gelatinous zooplankton. This book explores the intriguing marine plankton communities of the SWA region of South America encompassing low to high latitude environments, framed by a complex hydrographic background and global climate change. This vast and iconic region has been largely under-recognized and under-studied. However, in recent years a strong interest has emerged along with the acknowledgment of its high biological productivity. The book concludes by discussing conservation in the region, highlighting regional biodiversity hotspots where the challenges of climate change, habitat loss, and other threats to biodiversity may be particularly acute. Plankton Ecology of the Southwestern Atlantic is a timely synthesis of the field, setting a new baseline for future research. It will be important reading for both researchers and graduate students, and will also be of interest and use to a professional audience of oceanographers, conservation biologists, stake holders and educated science enthusiasts

Marine Ecosystems and Global Change by Manuel Barange,John G. Field,Roger P. Harris,Eileen E. Hofmann,R. Ian Perry,Francisco Werner Pdf

Global environmental change (including climate change, biodiversity loss, changes in hydrological and biogeochemical cycles, and intensive exploitation of natural resources) is having significant impacts on the world's oceans. This book advances knowledge of the structure and functioning of marine ecosystems, and their past, present, and future responses to physical and anthropogenic forcing. It illustrates how climate and humans impact marine ecosystems, providing a comprehensive review of the physical and ecological processes that structure marine ecosystems as well as the observation, experimentation, and modelling approaches required for their study. Recognizing the interactive roles played by humans in using marine resources and in responding to global changes in marine systems, the book includes chapters on the human dimensions of marine ecosystem changes and on effective management approaches in this era of rapid change. A final section reviews the state of the art in predicting the responses of marine ecosystems to future global change scenarios with the intention of informing both future research agendas and marine management policy. Marine Ecosystems and Global Change provides a detailed synthesis of the work conducted under the auspices of the Global Ocean Ecosystems Dynamics (GLOBEC) programme. This research spans two decades, and represents the largest, multi-disciplinary, international effort focused on understanding the impacts of external forcing on the structure and dynamics of global marine ecosystems.

Future Of Marine Life In A Changing Ocean, The: The Fate Of Marine Organisms And Processes Under Climate Change And Other Types Of Human Perturbation by M Debora Iglesias-rodriguez Pdf

This book brings together the state of our knowledge on the interactions between climate change and marine biota. It focusses broadly on the environmental stressors during the Anthropocene period; when human activities started to have a significant global impact on earth's geological imprint and ecosystems. This period of rapid change is accompanied by rising carbon dioxide levels, increasing global temperatures, loss of oxygen in aquatic systems, and the fast release of pollutants into the environment among many other environmental stressors originating from large scale human activities, such as widespread overfishing.The Future of Marine Life in a Changing Ocean starts by providing the reader with a brief background on fundamental concepts in ocean science and climate. It then moves on to a brief description of recent changes in marine chemistry such as ocean acidification, a decline in oxygen levels in the oceans, ocean warming, and marine pollution, with some examples of shifts in ecosystem diversity. The chapters discuss these topics in the context of how a changing ocean impacts ecosystem health, the biological carbon pump, the sequestration of carbon dioxide from the surface ocean into the deep sea, and the perceived notion of the ocean's unlimited resilience to maintain its role as a 'carbon reservoir'. Topics include threats to marine diversity, ecosystem function, latitudinal shifts in productivity and diversity, and changes in global cycling of elements such as carbon. It concludes with an analysis of the impact of climate change on food security.Written for undergraduate and graduate students, and researchers in the natural and social sciences, this book provides a science background to study environmental change in marine ecosystems as well as a science framework to study policy, marine law and the economics of climate change. This book is an essential read for anyone hoping to understand key challenges facing our oceans.

Plankton by Iain Suthers,David Rissik,Anthony Richardson Pdf

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.

Global Ecology and Oceanography of Harmful Algal Blooms by Patricia M. Glibert,Elisa Berdalet,Michele A. Burford,Grant C. Pitcher,Mingjiang Zhou Pdf

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.
