Marinbiologi

Marine Biology covers the basics of marine biology with a global approach, using examples from numerous regions and ecosystems worldwide. This introductory, one-semester text is designed for non-majors. Authors Castro and Huber have made a special effort to include solid basic science content needed in a general education course, including the fundamental principles of biology, the physical sciences, and the scientific method. This science coverage is integrated with a stimulating, up-to-date overview of marine biology.

A concise but comprehensive introduction to the biology of standing waters (lakes and ponds). As with other books in the Biology of Habitats Series, the emphasis in this book is on the organisms that dominate freshwater environments. Management and conservation aspects are also considered. The first edition of the book published in 1998 with a second, revised edition in 2005. There has been significant development in the field since the last revision appeared, particularly in the ecology of lakes and ponds in subtropical and tropical areas, and a new revision of this now classic text is timely.

I denna bok beskrivs majoriteten av världens 534 hajar systematiskt i ordningar och familjer. Boken är ett referensverk för alla som vill lära sig om hajar och innehåller även mängder av illustrationer. Dessutom förekommer några inledande kapitel om hajbiologi och vad som definierar en haj samt en ordlista. Varje år upptäckts det i snitt 10 nya arter av hajar. Visste du att det finns nio arter av hammarhajar? Den senaste hammarhajarten beskrevs 2013. I Sverige har 15 hajarter rapporterats och den största uppnår 10 meter i längd. En av dessa svenska hajar är håkäringen som kan uppnå 7 meter i längd och bli 400 år gammal. Under 2004 beskrevs en nära släkting till håkäringen, den antarktiska håkäringen som uppskattas bli 6 meter lång vilket gör den till en av världens största rovfiskar. Än idag finns stora hajar kvar att upptäcka i de gränslösa oceanerna. I Guide till världens hajar berättar, marinbiologen David C. Bernvi, om den otroliga diversitet som förekommer hos hajfiskar. Han har tidigare skrivit Världens Hajar Del 1 och Världens Hajar Del 2 samt Vithajen. David C. Bernvi har en masterexamen i marinbiologi från Stockholms universitet och forskar på vithaj i Sydafrika.

Dive into this uniquely elegant visual exploration of the sea An informative and utterly beautiful introduction to marine life and the ocean environment, The Science of the Ocean book brings the riches of the underwater world onto the printed page.Astounding photography reveals an abundance of life, from microscopic plankton to great whales, seaweed to starfish. Published in association with the Natural History Museum, the book explores every corner of the oceans, from coral reefs and mangrove swamps to deep ocean trenches.Along the way, and with the help of clear, simple illustrations, it explains how life has adapted to the marine environment, revealing for example how a stonefish delivers its lethal venom and how a sponge sustains itself by sifting food from passing currents. It also examines the physical forces and processes that shape the oceans, from global circulation systems and tides to undersea volcanoes and tsunamis.To most of us, the marine world is out of reach. But with the help of photography and the latest technology, The Science of the Ocean brings us up close to animals, plants, and other living things that inhabit a fantastic and almost incomprehensibly beautiful other dimension.

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.

The follow-up to the BBC Radio 4 Book of the Week Other MindsA Times and Sunday Times Book of the YearA Waterstones Best Book of 2020 The scuba-diving philosopher explores the origins of animal consciousness. Dip below the ocean’s surface and you are soon confronted by forms of life that could not seem more foreign to our own: sea sponges, soft corals and flower-like worms, whose rooted bodies and intricate geometry are more reminiscent of plant life than anything recognisably animal. Yet these creatures are our cousins. As fellow members of the animal kingdom – the Metazoa – they can teach us about the evolutionary origins of not only our bodies, but also our minds.In his acclaimed book, Other Minds, Peter Godfrey-Smith explored the mind of the octopus – the closest thing to an intelligent alien on Earth. In Metazoa, he expands his inquiry to animals at large, investigating the evolution of experience with the assistance of far-flung species. Godfrey-Smith shows that the appearance of the first animal body form well over half a billion years ago was a profound innovation that set life upon a new path. He charts the ways that subsequent evolutionary developments – eyes that track, for example, and bodies that move through and manipulate the environment – shaped the lives of animals. Following the evolutionary paths of a glass sponge, soft coral, banded shrimp, octopus and fish, then moving onto land and the world of insects, birds and primates like ourselves, Metazoa gathers these stories together to bridge the gap between matter and mind and address one of the most important philosophical questions: what is the origin of consciousness?Combining vivid animal encounters with philosophy and biology, Metazoa reveals the impossibility of separating the evolution of our minds from the evolution of animals themselves.

Seaweed is so familiar and yet its names - pepper dulse, sea lettuce, bladderwrack - are largely unknown to us. In this short, exquisitely illustrated portrait, the Dutch poet and artist Miek Zwamborn shares her discoveries of its history, culture and use, from the Neolithic people of the Orkney Islands to sushi artisans in modern Japan. Seaweed troubled Columbus on his voyages across the Atlantic, intrigued von Humboldt in the Sargasso Sea and inspired artists from Hokusai to Matisse. Covering seaweed's collection by Victorians, its adoption into fashion and dance and its potential for combating climate change, and with a fabulous series of recipes based around the 'truffles of the sea', this is a wonderful gift for every nature lover's home.

Korallernas planet är en personlig och initierad skildring av korallreven och deras betydelse för både människor och miljö.

Koraller är några av planetens viktigaste arkitekter och byggmästare. De har inte bara byggt upp de färgsprakande och artrika korallrev vi ser i naturfilmer eller när vi snorklar i tropikerna på semestern. De finns dessutom i gotländska raukar och i dopfunten på Drottningholms slott. I Sverige finns det ett litet hotat men levande korallrev, på hundra meters djup utanför Kosteröarna på den svenska västkusten.

Det finns fortfarande ungefär hundra gånger fler koraller än människor på vår planet. Men medan vi människor har blivit dubbelt så många de senaste 40 åren, har korallerna halverats på samma tid. FN:s klimatpanel IPCC har slagit fast att 99 procent av världens korallrev förväntas att dö om den globala medeltemperaturen höjs med två grader.

Vilka är bovarna i dramat? Är det för sent att göra något åt problemen? Hur gör forskarna för att ställa diagnos och komma på vilken medicin som behövs för att rädda reven?

Fredrik Moberg är korallrevsforskare och hållbarhets-expert. Han debuterade med Den uppfinningsrika planeten (2021).

An engaging and richly illustrated exploration of the natural history of seaweeds and other algaeAs photosynthetic organisms, seaweeds and other algae transfer billions of tons of carbon globally from the atmosphere to the deep ocean each year. Coming in all manner of colors, shapes, and sizes, from bioluminescent single-celled algae to giant kelps, they form the basis of most marine food webs, and are found in almost all environments on the planet. Touted as the biofuel of the future, seaweeds and algae also hold promise for biodegradable packaging, offer a nutritious food source, and exhibit antiviral and antitumor properties.Combining accessible text with stunning images and graphics, this book takes a deep dive to explore the unique characteristics of seaweeds and other algae, outlining their extraordinary evolution as well as their morphology, life histories, ecology, and uses. Offering rare insights into the algal world, The Lives of Seaweeds is essential reading for naturalists and marine life enthusiasts.

Reconceives whale songs as a sophisticated sonar system, revealing incredible insights into these creatures' intelligence and behavior.With breathtaking complexity and haunting beauty, the songs of whales have long fascinated scientists. Whales are the only mammals that can sing continuously for ten hours or more, changing the unique songs they sing every year. In Why Whales Sing, bioacoustician and cognitive scientist Eduardo Mercado transforms our understanding of these enigmatic sounds and proposes a groundbreaking theory that challenges decades of established science. Fifty years of field research have led most scientists to conclude that humpback whales sing for the same reason that birds do: to advertise their sexual fitness. But if whale songs are nothing more than tools of attraction, why do whales sing even when they're alone and there are no listeners nearby? In light of modern advances in neuroscience and ocean acoustics, Mercado reaches the surprising conclusion that whales may not actually be "singing," but rather engaging in an activity more commonly associated with dolphins and bats—echolocating—which enables them to see their world with sound. By incessantly streaming sounds while listening closely to the returning echoes, whales may be actively tuning their brains in ways that allow them to monitor the movements of silent whales located miles away.Sophisticated, long-range sonar can enable whales to perceive their vast underwater worlds in unimaginable ways. From the military origins of whale song recordings to the persistent mysteries of cetacean communication, this book displays the wonder of whales and reshapes how we view their intelligence, behavior, and acoustic mastery.

From the author of the international Bestseller BreathCovering a diving championship in Greece on a hot and sticky assignment for Outside magazine, James Nestor discovered free diving. He had stumbled on one of the most extreme sports in existence: a quest to extend the frontiers of human experience, in which divers descend without breathing equipment, for hundreds of feet below the water, for minutes after they should have died from lack of oxygen. Sometimes they emerge unconscious, or bleeding from the nose and ears, and sometimes they don't come up at all. The free divers were Nestor's way into an exhilarating and dangerous world of deep-sea pioneers, underwater athletes, scientists, spear fishermen, billionaires and ordinary men and women who are poised on the brink of some amazing discoveries about the ocean. Soon he was visiting the scientists who live 60ft underwater (and are permanently high on nitrous dioxide), swimming with the notorious man-eating sharks of Réunion and descending thousands of feet in a homemade submarine. And on the way down, he learnt about the amazing amphibious reflexes activated in the human body under deep-water conditions, why dolphins were injected with LSD in an attempt to teach them to talk, and why sharks like AC/DC. The sea covers seventy per cent of Earth's surface, and still contains answers to questions about the world we are only beginning to ask: Deep blends science and adventure to uncover its amazing secrets.

On dry land, most organisms are confined to the surface, or at most to altitudes of a hundred meters - the height of the tallest trees. In the oceans, though, living space has both vertical and horizontal dimensions: with an average depth of 3,800 meters, the oceans offer 99 percent of the space on Earth where life can develop. And the deep sea, which has been immersed in total darkness since the dawn of time, occupies 85 percent of ocean space, forming the planet's largest habitat. Yet, these depths abound with mystery. The deep sea is mostly uncharted - only about 5 percent of the seafloor has been mapped with any reasonable degree of detail - and we know very little about the creatures that call it home. Current estimates about the number of species yet to be found vary between ten and thirty million. The deep sea no longer has anything to prove; it is without doubt Earth's largest reservoir of life. Combining the latest scientific discoveries with astonishing color imagery, "The Deep" takes readers on a voyage into the darkest realms of the ocean.Revealing nature's oddest and most mesmerizing creatures in crystalline detail, "The Deep" features more than two hundred color photographs of terrifying sea monsters, living fossils, and ethereal bioluminescent creatures, some photographed here for the very first time. Accompanying these breathtaking photographs are contributions from some of the world's most respected researchers that examine the biology of deep-sea organisms, the ecology of deep-sea habitats, and the history of deep-sea exploration. An unforgettable visual and scientific tour of the teeming abyss, "The Deep" celebrates the incredible diversity of life on Earth and will captivate anyone intrigued by the unseen - and unimaginable - creatures of the deep sea.

Aquatic systems exhibit incredible diversity - from mountain streams to deep oceans, from lakes and ponds to the estuaries that link river and sea. Despite their distinct characters, however, these systems share common properties and, at the level of ecology, are not all that different after all. But how can this be?Ecology of Aquatic Systems brings together coverage of freshwater and marine systems to illustrate the principles and properties that unify aquatic systems. Using examples drawn from a wide geographical range, the book presents a broad survey of the field that acts as the ideal foundation for further study.Opening with a review of the different types of aquatic system and their interconnected nature, and the diversity of life within aquatic systems, the book goes on to explore the key types of aquatic habitat, emphasising the ecological themes that pervade each system.Written with students in the centre of the frame, Ecology of Aquatic Systems retains the succinct, lucid style for which the first edition was praised, and includes cross-references throughout, a substantial glossary, and extensive index, to help readers engage with, and fully understand, the material presented.With the global importance of aquatic systems becoming more apparent - and the need for effective management of these systems becoming increasingly clear - there has never been a more important time for students to fully grasp the fundamentals of aquatic systems. Ecology of Aquatic Systems is the ideal course companion to achieve this goal.Online Resources:For registered adopters of the text:- Figures from the book in electronic format, ready to download;- A testbank of multiple-choice questions, for use in formative or summative assessmentFor students:- Hyperlinks to literature articles cited in the text

SHORTLISTED FOR THE WOMEN'S PRIZE FOR NON-FICTIONLONGLISTED FOR THE BAILLIE GIFFORD PRIZE FOR NON-FICTIONNo matter where we live, 'we are all ocean people,' Helen Scales observes in her bracing yet hopeful exploration of the future of the ocean. Beginning with its fascinating deep history, Scales links past to present to show how prehistoric ocean ecology holds lessons for the ocean of today.In elegant, evocative prose, she takes us into the realms of animals that epitomize current increasingly challenging conditions, from emperor penguins to sharks and orcas. Yet despite these threats, many hopeful signs remain, in the form of highly protected reserves, the regeneration of seagrass meadows and giant kelp forests and efforts to protect coral reefs.Offering innovative ideas for protecting coastlines and cleaning the toxic seas, Scales insists we need more ethical and sustainable fisheries and must prevent the other existential threat of deep-sea mining. Inspiring us all to maintain a sense of awe and wonder at the majesty beneath the waves, she urges us to fight for the better future that still exists for the ocean.
