Animal Science

Animal scientists have long considered domestic livestock to be too dumb to know how to eat right, but the lifetime research of animal behaviorist Fred Provenza and his colleagues has debunked this myth. Their work shows that when given a choice of natural foods, livestock have an astoundingly refined palate, nibbling through the day on as many as fifty kinds of grasses, forbs, and shrubs to meet their nutritional needs with remarkable precision.

Since the 1970s, the science of primatology has been dominated by women—a unique reversal, as men usually outnumber women in science, technology, engineering and math (STEM) fields. Today, one of those women is primatologist Keriann McGoogan, who has traveled to the far corners of the earth in search of wild primates. In Sisters of the Jungle, McGoogan combines stories about her own studies of howler monkeys (the loudest living primate) and lemurs (the most endangered group of animals on the planet) with those of the women who paved the way.

At first Conor is excited to return to his old home, but when the four young heroes are betrayed by a familiar face, the hunt for the Great Beast becomes a race for their lives. But the real danger may be lying just ahead....

There is more than one way for animals to prepare for winter. Some, such as mice, foxes, and moose, simply tolerate the cold. Of course, black bears hibernate, but chipmunks, wood frogs, and garter snakes do, too. And then there are the creatures that migrate, including hummingbirds, blue whales, and even earthworms!

Whenever middle-aged desert tour guide Forrest Bryant Johnson went out on his daily walks into the Mojave, all was usually peaceful and serene. But one beautiful summer day in 1987, Forrest heard a cry of distress. Following the cries, he came upon a small bobcat kitten, injured, orphaned, and desperately in need of help. So Forrest took his new feline friend home for a night.

Rex Dexter is itching to have a dog. His parents surprise him with a box. A box with holes. A box with holes and adorable scratchy noises coming from inside. Could it be? Yes! It has to be! A...a...chicken? One hour and 14 minutes later, the chicken is dead (by a steamroller), Rex is cursed (by the Grim Reaper), and wild animals are haunting Rex's room (hounding him for answers). Even his best friend, Darvish, is not going to believe this, and that kid believes everything.

Because winter drastically affects the most elemental component of all life---water---radical changes in a creature's physiology and behavior must take place to match the demands of the environment.

Rachel's got some pretty strange stuff happening. She can't control her morphing. One minute, she's doing homework. The next, she's morphing a full-grown crocodile, and - without returning to human form - she becomes an elephant. That's when the floor gives way and Rachel finds herself looking up at what used to be the kitchen ceiling. What's going on? No one's sure, but Rachel and the other Animorphs have to figure it out - quickly. Because if someone sees Rachel's out-of-control morphing, the other Animorphs are in for some serious trouble.

No matter how cushy their lives, dogs live on our terms. They compromise their freedom and instinctual pleasure, as well as their innate strategies for coping with stress and anxiety, in exchange for the love, comfort, and care they get from us. But it is possible to let dogs be dogs without wreaking havoc on our lives, as biologist Marc Bekoff and bioethicist Jessica Pierce show in this fascinating book. They begin by illuminating the true nature of dogs and helping us "walk in their paws".

As Charles Darwin suggested more than a century ago, the differences between animals and humans are of degree and not of kind. Not long ago, ethologists denied that animals had emotions or true intelligence. Now, we know that rats laugh when tickled, magpies mourn as they cover the departed with greenery, female whales travel thousands of miles for annual reunions with their gal pals, seals navigate by the stars, bears hum when happy, and crows slide down snowy rooftops for fun.

The last time Rachel and her friends entered the giant Yeerk pool beneath their town things went very bad. This time they plan to be careful, and sneak in as roaches, just to spy. Once they're inside, though, the team gets caught. But right as things are looking their most dire, everything stops. Everything. Then Rachel and the Animorphs hear a voice. It belongs to a very old, very powerful being, and it says it can save them. But if it does, the Earth will be defenseless.
