In recent years it has become increasingly clear that chemical interactions play a fundamental role in aquatic habitats and have far-reaching evolutionary and ecological consequences. A plethora of studies have shown that aquatic organisms from most taxa and functional groups respond to minute concentrations of chemical substances released by other organisms. However, our knowledge of this "chemical network" is still negligible. Chemical interactions can be divided into two larger sub-areas based on the function of the chemical substance. First, there are interactions where chemical substances are toxic to other organisms and are used as a defence against consumers (including both herbivores and predators) or a weapon against competitors (allelopathy). Second, chemical substances may be used as a source for information of the environment; for example: how can I find the optimal habitat, the best food, the nicest partner, and avoid being eaten? Aquatic organisms are able to detect and respond to extremely low concentrations of chemical cues to answer all these questions. The book aims at connecting these intriguing chemical interactions with traditional knowledge of organism interactions. Chemical Ecology of Aquatic Systems covers a wide range of studies, both plant and animal, from different geographic regions and habitats - pelagic as well as benthic. Most of the chemical interactions are similar in freshwater and marine habitats and this book therefore strives at integrating work on both systems.

Being essential to the survival of civilisations, rivers run through mythology - think of ancient Egypt - and religion - think of the Ganges and Hinduism. And they continue to inspire writers and artists - think of Mark Twain's Mississippi and John Steinbeck's Salinas. From the Ganges rising in the Himalayas to the Nile Delta, from the Amazon rainforest to the Bow River flowing out of the Rocky Mountains, from the Rhine to the Rhone, Yangtze to the Mekong, Danube to the Volga to the Ebro, Rivers explores the grandest and most interesting rivers around the world. Arranged by continent, the book reveals the fascinating stories of how rivers have supported and shaped civilisations, the significance that rivers have gained in religion and myth, the battles that have been fought over them, the borders that they have marked, and how rivers have altered their courses, thus changing lives and livelihoods. Illustrated with more than 200 spectacular colour photographs supported by expert captions, Rivers is a fascinating journey from the mountains to the sea.

BBC R4 Book of the Week 'Brilliant' Guardian 'Fascinating and often delightful' The Times What if intelligent life on Earth evolved not once, but twice? The octopus is the closest we will come to meeting an intelligent alien. What can we learn from the encounter? In Other Minds, Peter Godfrey-Smith, a distinguished philosopher of science and a skilled scuba diver, tells a bold new story of how nature became aware of itself - a story that largely occurs in the ocean, where animals first appeared. Tracking the mind's fitful development from unruly clumps of seaborne cells to the first evolved nervous systems in ancient relatives of jellyfish, he explores the incredible evolutionary journey of the cephalopods, which began as inconspicuous molluscs who would later abandon their shells to rise above the ocean floor, searching for prey and acquiring the greater intelligence needed to do so - a journey completely independent from the route that mammals and birds would later take. But what kind of intelligence do cephalopods possess? How did the octopus, a solitary creature with little social life, become so smart? What is it like to have eight tentacles that are so packed with neurons that they virtually 'think for themselves'? By tracing the question of inner life back to its roots and comparing human beings with our most remarkable animal relatives, Godfrey-Smith casts crucial new light on the octopus mind - and on our own.

This book makes the connection between the tourism industry - as a major engine of the world economy - and the realm of artificial reefs, often inaccessible and forgotten by the public. By stimulating both those who work and in tourism and in artificial reefs to share experiences, transmit testimonies, make efforts, and develop new innovative and value-creating possibilities for society. This theme has great potential and impact. It allows knowledge transfer between research science on artificial reefs, companies, and the tourism sector, generating wealth for society. This book is of interest to all entrepreneurs, researchers, academics and students who work or are interested in exploring new ways of developing and practicing tourism, using structures that are submerged. The use of technologies developed by Industry 4.0 may have enormous potential in facilitating the establishment of bridges between tourism and reef structures and maximizing this potential.

In today's environmental and economic climate, it is important for businesses to drive development towards sustainable and zero-waste industries, responsibly leveraging renewable low-cost inputs to generate high-value outputs for the global market. Marine macroalgae presents modern businesses with opportunities for the development of a new and vibrant industry sector that largely fulfills these requirements. Harnessing Marine Macroalgae for Industrial Purposes in an Australian Context: Emerging Research and Opportunities provides emerging perspectives on the theoretical and practical aspects of developing a new business sector within the bio-marine industry. Featuring coverage on a broad range of topics such as competitive advantage, food industry, and production systems, this publication is ideally designed for environmental researchers, business students, engineers, and academicians seeking current research on the economics, regulation, and policy in supporting the development of the macroalgal industry sector in the global market.

The increasingly widespread production of toxins by marine and freshwater microalgae raises serious concerns regarding seafood and drinking water safety. This book compiles studies on the influence of climate change on the spreading of toxin-producing species in aquatic systems. The chemistry and biology of toxin production is revised and an outlook on control and prevention of the toxins' impact on human and animal health is given.
