The marine environment is the largest, most important, and yet most mysterious habitat on our planet. It contains more than 99% of the world's living space; produces half of its oxygen; plays a critical role in regulating its climate; and supports a remarkably diverse and exquisitely adapted array of life forms, from microscopic viruses, bacteria, and plankton to the largest existing animals. As the 21st century progresses human activities, such as overfishing, coastal development, plastic pollution, oil spills, nutrient pollution, the spread of exotic species, and the emission of climate changing greenhouse gases are posing a significant threat to the marine environment and to many of its life forms. In this unique Very Short Introduction, Philip Mladenov provides a comprehensive overview of marine biology, providing a tour of marine life and marine processes that ranges from the polar oceans to tropical coral reefs; and from the intertidal to the hydrothermal vents of the deep sea.

The oceans are our planet's most distinctive and imposing natural habitat. They cover 71 per cent of its surface; support a remarkably diverse and exquisitely adapted array of life forms, from microscopic viruses, bacteria, and plankton to the largest existing animals; and possess many of Earth's most significant, intriguing, and inaccessible ecosystems. In an era in which humans are significantly altering the global environment, the oceans are undergoing rapid and profound changes. The study of marine biology is thus taking on added importance and urgency as people struggle to understand and manage these changes to protect our marine ecosystems. Healthy oceans produce half of the oxygen we breathe; stabilize our climate; create ecosystems that protect our coasts from storms; provide us with abundant food; and host diverse organisms that provide us with natural products for medicine and biotechnology. In this Very Short Introduction, marine biologist Philip Mladenov provides an accessible and up-to-date overview of marine biology, offering a tour of marine life and marine processes that ranges from the unimaginably abundant microscopic organisms that drive the oceans' food web to the apex predators that we exploit for food; from polar ocean ecosystems to tropical coral reefs; and from the luxurious kelp beds of the coastal ocean to deep-ocean hydrothermal vents where life exists without the energy of the sun. Throughout the book he considers the human impacts on marine life including overfishing, plastic and nutrient pollution, the spread of exotic species, and ocean warming and acidification. He discusses the threats these pose to our welfare, and the actions required to put us on a path to a more sustainable relationship with our oceans so that they can be restored and protected for future generations. Mladenov concludes with a new chapter offering an inspiring vision for the future of our oceans in 2050 that can be realised if we are wise enough to accelerate actions already underway and be bold with implementing new approaches. The next decade will decide the state of the oceans that we leave behind for future generations.

In this expanded and revised edition of Sea Stars of British Columbia, originally published in 1981, Philip Lambert describes 43 species and subspecies of sea stars in the coastal waters of northwestern North America. Lambert has expanded the geographic area to include the region from Glacier Bay in southeastern Alaska to the waters of Juan de Fuca Strait and Puget Sound of northern Washington. The sea star fauna of this region is the most diverse of all the temperate waters of the world. The great age of the Pacific Basin, and the varied habitats along this complex coastline, created by scouring glaciers and other natural forces, have stimulated the evolution of many new forms. Although he covers the coastal waters down to 200 metres below the surface, Lambert lists 26 more species that live below 200 metres and 14 others that occur just outside the region covered by this book.

From folk music to worldbeat, world music holds the power to evoke the exotic and give voice to the voiceless. This new edition shows how dramatic political changes are affecting the ways in which people produce and listen to world music, and addresses how new technologies and the internet alter the way we disseminate and listen to it.
Very Short Introductions: Brilliant, Sharp, Inspiring Violence is part and parcel of human history and of human nature. It is one of our most distinctive traits, the one thing that all cultures and societies, across time, share in common. It has defined not only the ways in which individuals relate to each other, but also how collective entities and states have interacted with each other over the millennia. All societies are violent and all individuals have the capacity for violence. However, not all societies and not all individuals are equally violent, and nor does violence exist with the same intensity across cultures. This Very Short Introduction examines the more visible, physical acts of violence - interpersonal, gendered, collective, religious, sexual, criminal, and political - in the modern world. It explores how violence in the pre-modern world was different from the modern world, and what is significant about those differences. It also discusses what violence is by examining understandings of the ideas, values, and cultural practices embedded in an act of violence, and considering acts of violence as the outcome of a process dependent on the cultural context in which they take place. Along the way Dwyer considers some core questions, asking whether violence is always 'bad', and if there are any limits to human violence? Why is it that what was once considered acceptable - wife beating, duelling, slavery - at some point becomes unacceptable in some societies and cultures, and yet continues in others? And finally, are we becoming more or less violent? ABOUT THE SERIES: The Very Short Introductions series from Oxford University Press contains hundreds of titles in almost every subject area.

What is Nanotechnology and how will it affect us? Nanobots, nanoprobes, nanoswarms, nanogenes the list goes on. Nanotechnology is a staple of science fiction and has a rather chequered history when it comes to public perception: will swarms of sentient nanomachines ultimately take over the world or will nanotech give us nothing more than improved sun creams? As this Very Short Introduction shows, the science underpinning nanotechnology is equally as fascinating as the best nano-inspired sci-fi. In this book, Philip Moriarty introduces the key scientific themes and concepts underpinning the field, including interatomic and intermolecular forces, single atom imaging, quantum confinement, self-assembly, molecular machinery, and nanomagnetism. Moriarty includes results from ground-breaking scientific studies, such as scanning probe microscope images of atomic and molecular “landscapes”, providing visceral and intuitive insights into the nanoscopic world.

The Sun, as our nearest star, is of enormous importance for life on Earth - providing the warm radiation and light which allowed complex life to evolve. The Sun plays a key role in influencing our climate, whilst solar storms and high-energy events can threaten our communication infrastructure and satellites. This Very Short Introduction explores what we know about the Sun, its physics, its structure, origins, and future evolution. Philip Judge explains some of the remaining puzzles about the Sun that still confound us, using elementary physics, and mathematical concepts. Why does the Sun form spots? Why does it flare? As he shows, these and other nagging difficulties relate to the Sun's continually variable magnetism, which converts an otherwise dull star into a machine for flooding interplanetary space with variable radiation, high-energy particles and magnetic ejections. Throughout, Judge highlights the many reasons that the Sun is important, and why scientists engage in solar research.

No one wants to live in poverty. Few people would want others to do so. Yet, millions of people worldwide live in poverty. According to the World Bank, over 700 million people lived on less than US $2 a day in 2013. Why is that? What has been done about it in the past? And what is being done about it now? In this Very Short Introduction Philip N. Jefferson explores how the answers to these questions lie in the social, political, economic, educational, and technological processes that impact all of us throughout our lives. The degree of vulnerability is all that differentiates us. He shows how a person's level of vulnerability to adverse changes in their life is very much dependent on the circumstances of their birth, including where their family lived, the schools they attended, whether it was peacetime or wartime, whether they had access to clean water, and whether they are male or female. Arguing that whilst poverty is ancient and enduring, the conversation about it is always new and evolving, Jefferson looks at the history of poverty, and the practical and analytical efforts we have made to eradicate it, and the prospects for further poverty alleviation in the future.

Through the centuries, Russia has swung sharply between successful expansionism, catastrophic collapse, and spectacular recovery. This illuminating history traces these dramatic cycles of boom and bust from the late Neolithic age to Ivan the Terrible, and from the height of Communism to the truncated Russia of today. Philip Longworth explores the dynamics of Russia's past through time and space, from the nameless adventurers who first penetrated this vast, inhospitable terrain to a cast of dynamic characters that includes Ivan the Terrible, Catherine the Great, and Stalin. His narrative takes in the magnificent, historic cities of Kiev, Moscow, and St. Petersburg; it stretches to Alaska in the east, to the Black Sea and the Ottoman Empire to the south, to the Baltic in the west and to Archangel and the Artic Ocean to the north. Who are the Russians and what is the source of their imperialistic culture? Why was Russia so driven to colonize and conquer? From Kievan Rus'---the first-ever Russian state, which collapsed with the invasion of the Mongols in the thirteenth century---to ruthless Muscovy, the Russian Empire of the eighteenth century and finally the Soviet period, this groundbreaking study analyses the growth and dissolution of each vast empire as it gives way to the next. Refreshing in its insight and drawing on a vast range of scholarship, this book also explicitly addresses the question of what the future holds for Russia and her neighbors, and asks whether her sphere of influence is growing.
