Optics--a field of physics focusing on the study of light--is also central to many areas of biology, including vision, ecology, botany, animal behavior, neurobiology, and molecular biology. The Optics of Life introduces the fundamentals of optics to biologists and nonphysicists, giving them the tools they need to successfully incorporate optical measurements and principles into their research. Sonke Johnsen starts with the basics, describing the properties of light and the units and geometry of measurement. He then explores how light is created and propagates and how it interacts with matter, covering topics such as absorption, scattering, fluorescence, and polarization. Johnsen also provides a tutorial on how to measure light as well as an informative discussion of quantum mechanics. The Optics of Life features a host of examples drawn from nature and everyday life, and several appendixes that offer further practical guidance for researchers. This concise book uses a minimum of equations and jargon, explaining the basic physics of light in a succinct and lively manner. It is the essential primer for working biologists and for anyone seeking an accessible introduction to optics.

A seagoing scientist explores how life thrives in one of the most mysterious environments on EarthThe open ocean, far from the shore and miles above the seafloor, is a vast and formidable habitat that is home to the most abundant life on our planet, from giant squid and jellyfish to anglerfish with bioluminescent lures that draw prey into their toothy mouths. Into the Great Wide Ocean takes readers inside the peculiar world of the seagoing scientists who are providing tantalizing new insights into how the animals of the open ocean solve the problems of their existence.Sönke Johnsen vividly describes how life in the water column of the open sea contends with a host of environmental challenges, such as gravity, movement, the absence of light, pressure that could crush a truck, catching food while not becoming food, finding a mate, raising young, and forming communities. He interweaves stories about the joys and hardships of the scientists who explore this beautiful and mysterious realm, which is under threat from human activity and rapidly changing before our eyes.Into the Great Wide Ocean presents the sea and its inhabitants as you have never seen them before and reminds us that the rules of survival in the open ocean, though they may seem strange to us, are the primary rules of life on Earth.

A marvelously illustrated guide to color in the natural worldRecent years have seen tremendous strides in the fields of vision, visual ecology, and our own multilayered experience of color in life and the world. These advances have been driven by astonishing discoveries in neuroscience and evolutionary biology as well as psychology and design. This beautifully illustrated book unlocks nature’s colorful purpose, revealing how creatures see color as well as shedding light on the important part that it plays in animal behavior, from reproduction and communication to aggression and defense. Color in Nature also places the human experience and uses of color in the context of all the colors around us, both in the natural world and in the world that we humans create for our own pleasure and purpose. A wide-ranging survey of a vibrant and compelling topic, Color in Nature will open your eyes to new ways of perceiving the world.Features a wealth of stunning color illustrationsExplains what color is and how it happensCovers the physics, genetics, chemistry, physiology, and psychology of animal color perceptionDiscusses colors humans don’t see or rarely useSheds light on the evolution of colors for mating, hunting, fighting, deceiving, and hidingProvides insights into color blindness, bio-inspired colors, and people’s appreciation for art and design

Visual ecology is the study of how animals use visual systems to meet their ecological needs, how these systems have evolved, and how they are specialized for particular visual tasks. Visual Ecology provides the first up-to-date synthesis of the field to appear in more than three decades. Featuring some 225 illustrations, including more than 140 in color, spread throughout the text, this comprehensive and accessible book begins by discussing the basic properties of light and the optical environment. It then looks at how photoreceptors intercept light and convert it to usable biological signals, how the pigments and cells of vision vary among animals, and how the properties of these components affect a given receptor's sensitivity to light. The book goes on to examine how eyes and photoreceptors become specialized for an array of visual tasks, such as navigation, evading prey, mate choice, and communication. A timely and much-needed resource for students and researchers alike, Visual Ecology also includes a glossary and a wealth of examples drawn from the full diversity of visual systems.* The most up-to-date overview of visual ecology available* Features some 225 illustrations, including more than 140 in color, spread throughout the text* Guides readers from the basic physics of light to the role of visual systems in animal behavior* Includes a glossary and a wealth of real-world examples
