Marine Biology

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. ABOUT THE SERIES: The Very Short Introductions series from Oxford University Press contains hundreds of titles in almost every subject area. These pocket-sized books are the perfect way to get ahead in a new subject quickly. Our expert authors combine facts, analysis, perspective, new ideas, and enthusiasm to make interesting and challenging topics highly readable.

Marine biology is a branch of biology dedicated to the study of the marine environment and its life forms. This includes all marine organisms - from the smallest bacteria to the largest animals - and the interactions between them and their environment, the physical and chemical properties of marine ecosystems, the role of the oceans as a global system, among numerous other subjects. Separated into four distinct areas, this Marine Biology book introduces you to the fundamentals of marine biology, marine diversity, marine ecology, and the human impact on the marine environment. This Marine Biology Book begins with an introduction to the subject, its subfields, interrelationship with other disciplines and the main roles and responsibilities of a marine biologist. You'll discover theories that aim to explain the formation of the Earth's oceans and the development of the earliest life forms and explore the physical and chemical properties that enable the marine environment to support life. We'll observe marine diversity, beginning with organisms that are invisible to the naked eye, yet are essential to the oceans and contribute to the planet's oxygen production. You'll learn about marine invertebrates - how they are classified and how they've evolved to survive in the ocean - and marine vertebrates, including birds, fishes, reptiles, and marine mammals, and how they have adapted to ocean life. You'll learn about marine ecology - exploring the different ecosystems and habitats that exist within the marine environment, the populations and communities and the interactions that take place between them and their environment, and the food chain of marine organisms and its impact on the structure and productivity of the global system. Finally, the book looks at the impact humanity has had on the marine environment. We'll look at human activities such as overfishing, the introduction of invasive species, and different types of pollution. The book explains how the climate crisis impacts the ocean and the adaptation and survival of marine life, and what is being done to protect, recover, and conserve marine ecosystems and ensure the sustainable use of its resources.

We present you with an updated reference book aimed for upper-level undergraduate and graduate students interested in Marine Biology. The textbook is designed to introduce the fundamentals of marine organisms and their ecological roles in the world’s oceans, and is organized by functional groups, emphasizing marine biodiversity rather than systematics or habitats. Each chapter has been written and peer-reviewed by renowned international experts in their respective fields, and includes updated information on relevant topics, from the microbial loop and primary production in the oceans, to marine megafauna and the impacts of projected climate change on marine life and ecosystems.
