As more people settled in the American west, however, condors lost much of their habitat to human development. By 1982, fewer than 25 California condors lived in the wild. Read this book to find out more about California condors, how they came close to extinction, and what people are doing do help make sure condors stay...

The bald eagle is known to people around the world as a symbol of the United States. In the early 1800s, as many as 100,000 bald eagles lived in the United States.

Termites can invade homes and cause a lot of damage. Termites that invade new countries can damage more than just homes. The Formosan subterranean termite was accidentally brought to the United States on infested ships. These invaders have disrupted ecosystems and caused billions of dollars in damage to buildings, crops, and trees. Look inside to learn more about these termite invaders and find out what experts are doing to fight back.

Swarms of the dinner-plate-size invasive Australian Spotted Jellyfish have been reported from East Texas to Florida in the Gulf of Mexico and along the Atlantic coastlines of Florida and South Carolina. These creatures present a major threat to the shrimp fishery. Readers will be introduced to the concepts of invasive species and challenged to think critically about the cause, effect, and control of dangerous creatures.

Following the scientific process, this title provides instructions on how to conduct experiments that help students gain a better understanding of plants and plant life.
