When a species is introduced to a new habitat, the sequence of events that follows exhibits the fragility of the food chain and the connections between all living organisms. In Invasive Mammals, cases like the rabbit in Australia provide evidence to readers of how adaptations give some animals advantages over others. The causes and effects of human interaction teach students to appreciate their impact on the environment and what can be done when invasive species start to take over.

In Invasive Reptiles and Amphibians, readers are shown examples of invasive snakes, frogs, and lizards to reveal the pattern of species introduction and habitat takeover. Identifying the adaptations of species like the Cane Toad, the title teaches students to compare the strengths and weaknesses of Earth's animals. The susceptibility of habitats such as Florida's emphasizes the delicacy of the food chain. By analyzing and comparing cases of invasive species, readers discover how humans impact the natural world and the work that must be done to keep the balance.

Capybaras are the largest rodents on Earth. Learn about their history, behavior, lifecycle, and the conservation efforts that are being done to protect these furry creatures.

Saltwater Crocodiles are among the largest reptiles on Earth. Learn about their history, behavior, lifecycle, and the conservation efforts that are being done to protect these prehistoric hunters descended from dinosaurs.

This book provides in-depth explorations of genetic cloning, including the history of cloning and the types of artificial cloning for both plants and animals, with fascinating examples. It also explains the possibility of using the gene therapy to cure diseases.

This study of macroeconomics combines treatment of opposing theories with a presentation of evidence to point the way toward a reconstructed macro research and policy programme.

The field of genetics is constantly in the news, and it is a major part of national and state standards for science education - both for learning the scientific concepts and principles themselves, and for enhancing critical thinking and providing students with a bigger picture of how science and scientific inquiry change the world. Written by a widely-respected author and teacher, "Genetics: The Science of Life" is designed to supplement the information provided in science textbooks and provide a platform for student discussions and debate on the latest developments in this fast-growing field. Each highly illustrated book focuses on a particular aspect of genetics in language that will appeal to readers ages 12 and up. Full-color line-art illustrates complex scientific concepts, and a variety of thematic sidebars highlight particular elements of genetics studies with engaging, real-life examples.
