Tundra  Caribou Body hair traps air that acts as insulator. Migrate during the winter in search of food and water  Wolves Take advantage of caribou movement patterns Prey on burrowers. ○ Lemmings (rodent) ○ Mice ○ Hares

Camouflage

Taiga- Coniferous Forests  Adaptations Hibernation Burrowers Thick body hair  Recall: Snow acts as an insulator

Coniferous Forests Some animals thrive in the winter conditions.

Deciduous Forests Stratification also exists within deciduous forests, Less tree biodiversity than found in rain forests.

Forest Floor  Decaying leaves provide a deep, rich layer of soil.  Insects and other invertebrates live in the soil and debris, feeding on abundant organic matter

Deciduous Forests  Winter Adaptations Migration ○ Many birds fly south to find warmer temperatures and food Hibernation ○ Some mammals reduce their metabolic activity so that they do not need as much food for energy.

Winter Adaptations in Deciduous Forests

Rain Forest  Recall Stratification

Niche Occupation  Two factors create enormous biodiversity in animal species. Stratification Diversity of tree species.

Rain Forest  Conditions vary at each forest level.  Different communities evolve to occupy each habitat.

Deserts  Recall: water is very limited.

Desert Reptiles  Have thick, scaly skin that prevents water loss

Desert Amphibians  Burrow in ground and sleep through the dry season. Tiger salamander fff ISN’T SCHOOL TOADALLY AWESOME!! RIGHT...JACOB & ANDY?? Sonoran Desert Toad

Invertebrates

Nocturnal Behavior Active at night ○ Hunting/feeding at night avoids the daytime heat.

Temperate Grasslands  Steppes  Prairies

Adaptations  During colder months, some animals hibernate in search of food and warmer temperatures.  During warmer months, large herbivores are supported by the abundant grasses.  Many smaller animals burrow to avoid fires and extreme temperatures throughout the year.

Prairie Dog Towns

Bison

Tropical Grasslands AKA Savanna  Animal populations concentrate around streams and watering holes. Recall: streams and watering holes are sources of water and more vegetation.  vertical feeding patterns: Animals eat vegetation at different heights to avoid competition for limited resources.

Vertical Feeding Pattern

More Adaptations  Many animals, such as zebras, migrate long distances in search of water.  Predators follow their migration patterns.
