In Biome Beasts: Desert Animals, readers will discover how desert animals survive and thrive in the driest places on the planet. Photos, text, and sidebars describe how these animals adapt to the challenging climate of these regions. Earth’s four desert biomes – hot, semiarid, coastal, and cold – each have their own set of challenges for the living things within them.
In Biome Beasts: Grassland Animals, readers will discover how these animals survive in prairies, steppes, and savannas around the world. Grassland biomes are home to a wide variety of animals. Whether grazing on grasses, building communities underground, or sailing overhead, animals have adapted to the challenges found in both temperate and tropical grassland biomes.
In Biome Beasts: Boreal Forest Animals, readers will discover how boreal beasts survive the harsh climate. The boreal forest teems with wildlife during the short, mild summer. This changes quickly when fall arrives. Only the living things that have adapted to the region’s freezing temperatures and frozen land can remain in the forest year-round.
In Biome Beasts: Deciduous Forest Animals, readers will discover how deciduous beasts rise to the challenges of the climate in each biome. Deciduous forests around the world are home to a variety of animals. Animals that are part of the temperate deciduous forest biome must adapt to the conditions of all four seasons to survive. Animals that are part of the tropical and subtropical deciduous forest biomes must adapt to both the wet and dry seasons.
In Biome Beasts: Tundra Animals, readers will discover how animals survive and thrive in the treeless tundra. Tundra biomes have the harshest climates in the world. From the tiny Arctic bumblebee to the huge polar bear, every animal that lives in the Arctic or alpine tundra biome has adapted physically or socially to the harsh conditions.
In Biome Beasts: Ocean Animals, readers will discover how animals survive in saltwater biomes and the skies above them. Most of Earth is covered by oceans and seas that are home to an amazing variety of animals. Some have adapted to life in the cold, dark aphotic zone. Others live in the disphotic zone where predators attack from above or below. Still others live in the top layer, the euphotic zone, where food is plentiful but competition for it is fierce.
In Biome Beasts: Estuary Animals, readers will discover how and why animals survive and thrive in these sheltered biomes. Life in the estuary is always changing. Ocean tides of saltwater flow in and out of the estuary and mix with the fresh water that flows from rivers and streams. The animals that swim or wade in the waters or make the mudflats their homes must have physical or social adaptations that allow them to live in the salty mix.
