As featured on BBC News and TIME'The potential of seaweed, or marine algae, to transform our world is huge… excellent book'New ScientistThe seaweed revolution is a fresh hope for tomorrow.Seaweed develops in water everywhere, from the eternal glaciers to lagoons heated by the sun, from seas saturated with salt to the fresh water of our rivers. Yet we only know how to cultivate a few dozen varieties, at most. Incredibly diverse, seaweed could help to bring back balance in our ecosystems through a wide range of applications. It could allow us to better feed human beings and animals, replace plastic and fertilizers, boost medical innovations, mitigate global warming, repair biodiversity and support economies in coastal communities where fish stocks are declining.Although seaweed has supported our development for millions of years, we have lost our connection with it and focused our efforts purely on land cultivation. Today a fast-growing global population, combined with climate, social and environmental crises, gives us compelling reasons to reconsider this forgotten treasure.‘This book is a must-read for anyone who cares about our planet's future'Mark Lynas, journalist and author of Our Final Warning: Six Degrees of Climate Emergency‘An essential read for anyone who is curious about the extraordinary powers of seaweed to change the world'Alexandra Cousteau, Head of Oceans 2050, and Jacques Cousteau's granddaughter‘Seaweeds and algae have an essential role to play in the solutions available to us and Vincent Doumeizel's The Seaweed Revolution shows us how'Ambassador Peter Thomson, UNSG's Special Envoy for the Ocean and former President of the UN General Assembly‘Seaweed holds the key to help solve many of the crises the world is facing'Carlos M.

A charming deep dive into the hidden world of seaweed, filled with fascinating facts and beautiful illustrations of the most sensuous family of water plants.Seaweed is so familiar, and yet we know so little about it. Even its names—pepper dulse, sea lettuce, bladderwrack—are mystifying.In this exquisitely illustrated portrait, poet and artist Miek Zwamborn shares discoveries of seaweed's history, culture, and science. We encounter its medicinal and gastronomic properties and long history of human use, from the Neolithic people of the Orkney islands to sushi artisans in modern Japan. We find seaweed troubling Columbus on his voyages across the Atlantic and intriguing Humboldt in the Sargasso Sea. We follow its inspiration for artists from Hokusai to Matisse, its collection by Victorians as pressed specimens in books, its adoption into fashion and dance, and its potential for combating climate change, as a sustainable food source and a means of reducing methane emissions in cattle.And, of course, we learn how to eat seaweed, through a fabulous series of recipes based around these “truffles of the seas.”

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 referenceresource for students, teachers and researchers engaged in the field of coastal research/management at regional and global scales.

This comprehensive book provides a unique overview of advances in the biology and ecology of marine protists. Nowadays marine protistology is a hot spot in science to disclose life phenomena using the latest techniques. Although many protistological textbooks deal with the cytology, genetics, ecology, and pathology of specific organisms, none keeps up with the quick pace of new discoveries on the diversity and dynamics of marine protists in general. The bookMarine Protists: Diversity and Dynamics gives an overview of current research on the phylogeny, cytology, genomics, biology, ecology, fisheries, applied sciences, geology and pathology of marine free-living and symbiotic protists. Poorly known but ecologically important protists such as labyrinthulids and apostome ciliates are also presented in detail. Special attention is paid to complex interactions between marine protists and other organisms including human beings. An understanding of the ecological roles of marine protists is essential for conservation of nature and human welfare. This book will be of great interest not only to scientists and students but also to a larger audience, to give a better understanding of protists'diverse roles in marine ecosystems.

Seaweeds, also known as macroalgae, are among the most important primary producers and act as ecological engineers on rocky coasts of the world's oceans. In addition to their extreme ecological importance they are also of high economic relevance. Complementing available textbooks with its more research-oriented approach, this volume contains 22 chapters by renowned experts, grouped in five parts. In Part I fundamental processes and acclimation strategies of seaweeds towards the abiotic environment are covered. Part II focuses on the multitude of biotic interactions in seaweed communities, and in Part III the reader is introduced to the structure and function of the main seaweed systems of the world. The chapters of Part IV highlight and discuss the effects of global and local environmental changes on seaweeds and their communities. In the final Part V a comprehensive overview of developments in seaweed aquaculture, industrial applications and the overall economic importance of seaweeds is provided. Summarizing the advances in seaweed biology achieved within the last few decades, this book also identifies gaps in the present knowledge and needs for future research.
