Brazil is home to equatorial, tropical, semi-arid, highland tropical, and subtropical climatic regions. The semiarid region of Northeastern Brazil, considered an area of drought polygon, has distinctive scrub vegetation referred to as Caatinga that covers over 10% of the Brazilian territory with approximately twenty million inhabitants. The Caatinga is considered one of the 37 Wilderness Areas of the World, and it plays an important role in the maintenance of regional macro-ecological processes, as well as indirectly supporting regions with biodiversity and endemism. The Brazilian semiarid region is also home to Neotropical fish species that occur in diversified aquatic ecosystems, exhibiting different strategies to survive and reproduce. In this scenario of fantastic diversity there exists an intensive and yet insufficiently known interaction of environmental factors and fish communities. To fully understand this it is necessary to know the details about how it works. For completed book description please visit our website at the link below.

As with other books in the Series, the emphasis is on the unique physiological characteristics of the fish, but with applications to questions of broad relevance in physiological ecology. A preliminary chapter introduces the aquatic environment and gives a general description of fish biology, evolution, and taxonomy. Subsequent sections discuss the particular problems of living in water, life in extreme environments, techniques for studying fish ecophysiology, and future research directions.

Marine and freshwater biotoxins are a well-known problem in food safety, mainly for filter-feeding mollusks and for freshwater aquaculture. This is a challenging matter since, in recent years, toxic algal blooms seems to grow in frequency and duration, leading to longer closure of harvesting areas, disruption in trade, mortality in farmed fish and a growing concern in producers, consumers and health authorities. Unfortunately, in recent years toxins from far latitudes are emerging, leading to new human health problems. Research and exhaustive knowledge of a problem makes it easier to draw a scenario where the best management strategies are gathered. This book combines all if the information related to food-borne illness associated with marine or freshwater biotoxins, the anthropogenic and environmental factors that cause the appearance of toxic episodes and all available analytical procedures for phycotoxins detection.

Georgie Codd is scared of fish. Really, really scared. She has spent her life beside the water, but won't so much as paddle in it. Even on dry land there's no escape: Georgie sees sharks in the dining room, squid tentacles in the street, has nightmares of being stranded at sea. She decides that the answer to overcoming this fear lies in travelling to Thailand, learning to dive and swimming with the biggest fish in the world: the massive, mighty whale shark. Could this immersive therapy actually work? There's only one way to find out. Georgie quits her job, leaves her life behind and plunges into a realm of strange creatures, hidden depths and intrepid diving adventurers. But as her quest expands across the oceans, her shark remains elusive and everything else starts to fall apart around her. For readers of The Outrun and The Salt Path, We Swim to the Shark is a meditation on diving, grief and what it takes to face our greatest fears. What readers are saying about We Swim to the Shark: 'Part travelogue, part odyssey and completely engaging. A must read' 'This book is so easy to devour . . . Plus it's full of fascinating facts about fish and how we can save our oceans' 'Adventurous, insightful, informative and entertaining'

A thrilling tour of the sea's most extreme species, coauthored by one of the world's leading marine scientists The ocean teems with life that thrives under difficult situations in unusual environments. The Extreme Life of the Sea takes readers to the absolute limits of the ocean world-the fastest and deepest, the hottest and oldest creatures of the oceans. It dives into the icy Arctic and boiling hydrothermal vents-and exposes the eternal darkness of the deepest undersea trenches-to show how marine life thrives against the odds. This thrilling book brings to life the sea's most extreme species, and tells their stories as characters in the drama of the oceans. Coauthored by Stephen Palumbi, one of today's leading marine scientists, The Extreme Life of the Sea tells the unforgettable tales of some of the most marvelous life forms on Earth, and the challenges they overcome to survive. Modern science and a fluid narrative style give every reader a deep look at the lives of these species. The Extreme Life of the Sea shows you the world's oldest living species. It describes how flying fish strain to escape their predators, how predatory deep-sea fish use red searchlights only they can see to find and attack food, and how, at the end of her life, a mother octopus dedicates herself to raising her batch of young. This wide-ranging and highly accessible book also shows how ocean adaptations can inspire innovative commercial products-such as fan blades modeled on the flippers of humpback whales-and how future extremes created by human changes to the oceans might push some of these amazing species over the edge.

Lagoons and estuaries are transition spaces between earth and sea. Beyond their expanse, geographic repartition, geomorphological, hydroclimatic and ecobiological diversity and biodiversity, they play an important role in regional economies and are some of the ecosystems most vulnerable to global change. Reinforced by numerous references, this book studies Mediterranean lagoonal and estuarine fishes whose diversity largely depends on the composition of neighboring marine and continental ichtyofauna. The authors describe their morphological, biological, ecological and behavioral characteristics by evoking their distinctive features and differences with their marine or freshwater homologues. Their adaptation strategies, elucidated thanks to recent advances in morphology, genetics and molecular biology, are recognized as a major advantage in the context of climate change. This book is for natural environment managers, engineers, teachers, students and researchers.

The species of hake, making up the genus Merluccius, are commercially important and currently largely over exploited, with many stocks badly depleted and showing only limited signs of recovery. From the end of the 1990s, concepts such as sustainability, ecosystem-based approaches to fisheries management, a code for the responsible conduct for fisheries, governance and others have emerged or have been considered by politicians, stakeholders and society. Moreover, new tools for stock assessment have been developed. But many hake stocks of the genus Merluccius show no sign of restoration. Hakes: Biology and Exploitation brings together a wealth of important information on the biology and exploitation of hake and hoki stocks around the world. Each chapter provides an overview of the fisheries of each species in an ecological and environmental context, looking at stock distribution, characteristics of the environment, life history, reproduction, diet, growth, mortality, pricing and markets of each geographical region and the hake species found there. With chapters written by regional experts on hake species and included within Wiley-Blackwell s prestigious Fish and Aquatic Resources Series, Hakes: Biology and Exploitation provides up-to-date and comparative information, including new approaches to fisheries management, for all those involved in fisheries management, aquatic ecology and biological sciences.

Lake Tanganyika, situated in the western rift system of East Africa, is the largest in volume of the African Great Lakes and the second deepest lake in the world.

The aquatic flora and fauna are remarkable for their diversity and high degree of endemicity, as well as for the numbers of species and genera present. The lake has attracted international interest and much has been written about it. With its comprehensive bibliography, this book should provide a foundation of information that will be useful in further studies.

This and the companion volume describe and illustrate more than 2000 species, form selected protozoans to fishes, found in the coastal waters of the British Isles and north-western Europe. They cover all benthic habitats, from the intertidal zone to approximately 30 metres depth, and also includes representatives of estuarine and supralittoral faunas. Each major animal group is briefly introduced, with notes on the morphology, biology, and ecology of representative species, together with suitable techniques for their collection and study. Short bibliographies list the most important specialist literature for each group. Identification is facilitated by dichotomous keys, first to families, and then to genera or species. Short diagnostic accounts are given for each family and higher taxon; descriptions of all species treated are followed by notes on their ecological and geographical distribution. All species are illustrated by line drawings, with related species grouped together to facilitate comparisons. The two volumes comprise the most comprehensive account of the marine fauna of British and adjacent waters ever produced. It is intended as a bench work for both the professional and amateur marine biologist, as well as for undergraduate and postgraduate students. It is essentially a practical work; taxonomic and synonymic detail is deliberately kept to a minimum, with emphasis given to identification procedures.

Aquaculture exemplifies the ongoing global struggle to strike a sustainable balance between the conflicting needs of a rapidly increasing world population, human health, ecosystem health, the welfare of wild and domesticated animals, and the economic principles of globalized economies. On the one hand, aquaculture has great potential for providing us with a healthy and nutritious food supply whilst alleviating pressure on captive fisheries and reducing fisheries-induced habitat destruction, overfishing, genetic modification of wild populations, and wholesale waste of bycatch. On the other hand, aquaculture relies heavily on clean water, an increasingly precious (and dwindling) resource that is subject to intense pressure of being used for many competing objectives. This concise primer introduces students to the basic concepts, opportunities, and challenges of aquaculture with an emphasis on ecological considerations. It provides a critical assessment of current aquaculture practices from a broad, interdisciplinary perspective and from the standpoint of how best to align the two major (and often conflicting) goals of future aquaculture development: minimizing reliance on ecosystem services whilst maximizing productivity. A Primer of Ecological Aquaculture provides an accessible and authoritative overview for a wide range of undergraduate majors ranging from biology, engineering, and environmental policy to business and management. It will also appeal to a more general academic audience who wish to gain a current overview of the field.
