Two of every five mammals on Earth are rodents, yet most people know little about this amazingly diverse order of animals. Rats and mice may be all too familiar, but what about gundis and degus? And did you know that porcupines are rodents, but rabbits are not? The Rodent Order explores the world of rodents, from prehistoric guinea pigs the size of horses to the Laotian rock rat, a "living fossil" recently found alive in the forests of Southeast Asia. The Rodent Order also examines the long relationship between people and rodents. For thousands of years, rodents have influenced human life as pests, food, pets, and carriers of disease. Today human activities are threatening the survival of some rodent species, but other rodents are flourishing-sometimes right under our noses. Book jacket.

The Bird Class sounds a warning about the threats that many of the world''s ten thousand bird species now face, and describes some of the actions being taken to protect them. Book jacket.

Ethology is the scientific study of animal behavior. It was widely thought that animal play, mostly in mammals, was part of Darwinian natural selection and somehow fit into survival of the fittest. However, animal researchers believe that animals play out of pure joy, rather than aiding in their survival. This jovial book about animal play, tells the secrets of, and the science behind, clever baboons that know which cars to break into for snacks, mighty elephants that grieve, tricky octopuses that squirt water, and beetles that read messages through their feet. This book includes explanative text by award-winning author Rebecca Stefoff and an extensive bibliography. Key scientific terms and phrases are explained and includes procedures for scientific observation.

Can animals feel empathy or have a consciousness? Through the extensive work from ethologists like Charles Darwin and Jane Goodall, it is widely thought that some animals do feel empathy. Research is ongoing, however, dogs, birds, elephants, rodents, and dolphins are thought to all have a moral compass. In what ways do these animal species show empathy or feeling? Through explanative based text by award-winning author Rebecca Stefoff, your readers will be challenged to notice animal behavior in a myriad of ways. Key scientific terms and phrases are explained and step-by-step guidance for scientific observation procedures are included.

Monerans, the most numerous life-forms on earth, are better known as bacteria. They are prokaryotes, organisms that consist of a single cell without a nucleus. Invisible to ordinary sight, bacteria were discovered in the seventeenth century, after the invention of the microscope. Then, in the 1970s, scientists using the new tool of DNA sequencing discovered another group of prokaryotes called the archaea. The Moneran Kingdom explains the differences between bacteria and archaea-two of the three domains of life on Earth-and provides an overview of milestones in microbiology. The reader is introduced to the structure and life cycle of the prokaryotes, the role of bacteria in the origins of life on earth, and the many ways monerans influence life for human beings-from disease to digestion to decomposing waste. Bacteria may be "germs," but they are vital to our continued survival. Book jacket.

The impact and ramifications of cases argued before the Supreme Court are felt for decades, if not centuries. Only the most important issues of the day and the land make it to the nine justices, and the effects of their decisions reach far beyond the litigants.
