Book Description
In Diatoms to Dinosaurs, Chris McGowan takes the reader on a fascinating journey through the natural world, and examines life in all its various forms. He imparts the excitement of discovery and the joy of understanding as he demonstrates the central importance of size and scale to the survival of living organisms. McGowan investigates a wide range of size-related phenomena, from the gliding mechanism of diatoms to blood pressure problems of dinosaurs. Questions asked -- and answered -- include: Will we ever see giant insects the size of pterodactyls? Why are ants so much stronger relative to body size than elephants? What do a clam, a condor, a tortoise, and a sturgeon have in common? How did the skeleton of a 28-ton Apatosaurus support its weight? How can blood get from the heart to the head of a giraffe without rupturing blood vessels? The author explicates the scientific concepts -- both physical and biological -- needed to inform the relevant phenomena: area/volume relations, metabolism and other basic physiology, kinetic energy, inertial forces, the biology of senescence, boundary layers, and Reynolds numbers. Numerous illustrations scattered throughout the text make the biophysical principles easily comprehensible to readers, regardless of their scientific sophistication.

Book Description
The aim of this new book series (Diatoms: Biology and Applications) is to provide a comprehensive and reliable source of information on diatom biology and applications. The first book of the series, Diatoms Fundamentals & Applications, is wide ranging, starting with the contributions of amateurs and the beauty of diatoms, to details of how their shells are made, how they bend light to their advantage and ours, and major aspects of their biochemistry (photosynthesis and iron metabolism). The book then delves into the ecology of diatoms living in a wide range of habitats, and look at those few that can kill or harm us. The book concludes with a wide range of applications of diatoms, in forensics, manufacturing, medicine, biofuel and agriculture. The contributors are leading international experts on diatoms. This book is for a wide audience researchers, academics, students, and teachers of biology and related disciplines, written to both act as an introduction to diatoms and to present some of the most advanced research on them.

Book Description
A fascinating study of the thousands of new animal species that walked in the footsteps of the dinosaurs—and the climate changes that brought them forth. The fascinating group of animals called dinosaurs became extinct some 65 million years ago (except for their feathered descendants). In their place evolved an enormous variety of land creatures, especially mammals, which in their way were every bit as remarkable as their Mesozoic cousins. The Age of Mammals, the Cenozoic Era, has never had its Jurassic Park, but it was an amazing time in earth’s history, populated by a wonderful assortment of bizarre animals. The rapid evolution of thousands of species of mammals brought forth many incredible creatures―including our own ancestors. Their story is part of a larger story of new life emerging from the greenhouse conditions of the Mesozoic, warming up dramatically about 55 million years ago, and then cooling rapidly so that 33 million years ago the glacial ice returned. The earth’s vegetation went through equally dramatic changes, from tropical jungles in Montana and forests at the poles. Life in the sea underwent striking evolution reflecting global climate change, including the emergence of such creatures as giant sharks, seals, sea lions, dolphins, and whales. Engaging and insightful, After the Dinosaurs is a book for everyone who has an abiding fascination with the remarkable life of the past.

Book Description
This book introduces you to creatures from the protist kingdom, from microscopic protozoans to seaweedlike algae. It examines the parts, life cycle, and reproduction of various types of protists. It also looks at the harmful effects some protists have on humans. Did You Know? The deadly disease malaria is caused in part by the protist Plasmodium. The fossils of one type of protist, the red algae, date back more than 500 million years. Paramecium, a well known protist, uses hairlike cilia to sweep food into its mouth.

Book Description
Over half a billion years ago life on earth took an incredible step in evolution, when animals learned to build skeletons. Using many different materials, from calcium carbonate and phosphate, and even silica, to make shell and bone, they started creating the support structures that are now critical to most living forms, providing rigidity and strength. Manifesting in a vast variety of forms, they provided the framework for sophisticated networks of life that fashioned the evolution of Earth's oceans, land and atmosphere. Within a few tens of millions of years, all of the major types of skeleton had appeared. Skeletons enabled an unprecedented array of bodies to evolve, from the tiniest seed shrimp to the gigantic dinosaurs and blue whales. The earliest bacterial colonies constructed large rigid structures - stromatolites - built up by trapping layers of sediment, while the mega-skeleton that is the Great Barrier Reef is big enough to be visible from space. The skeletons of millions of coccolithophores that lived in the shallow seas of the Mesozoic built the white cliffs of Dover. These, and insects, put their scaffolding on the outside, as an exoskeleton, while vertebrates have endoskeletons. Skeletons may be hydrostatic, or, as is common, made of calcium phosphate, or from carbonate, or silica - the latter used to create delicate and elegant designs by diatoms and radiolarians. They need to be light and strong for flight. Plants use tubes of dead tissue for rigidity and transport of liquids - which in the case of tall trees need to be strong enough to extend 100 m or more from the ground. Others simply stitch together a coating from mineral grains on the seabed. In Skeletons, Jan Zalasiewicz and Mark Williams explore the incredible variety of the skeleton innovations that have enabled life to expand into a wide range of niches and lifestyles on the planet. Discussing the impact of climate change, which puts the formation of some kinds of skeleton at risk, they also consider future skeletons, including the possibility that we might increasingly incorporate metal and plastic elements into our own, as well as the possible materials for skeleton building on other planets.
