Transcript

  • 1. BIOMES• Biome – physical environment that has characteristic plants & animals.• Example: Lizards + Cactus = Desert.
  • 2. Major Biomes• Tropical Rain Forest • Temperate Forest• Tropical Dry Forest • Northwestern• Tropical Savanna Coniferous Forest• Desert • Boreal Forest• Temperate Grassland • Tundra• Temperate Woodland & Shrupland Each biome is defined by a unique set of abiotic features, particularly climate, and has a characteristic ecological community.
  • 3. Tropical Savanna• Abiotic – Warm temperatures – Seasonal rainfall – Compact soil – Frequent fires due to lightening
  • 4. Tropical Savanna, cont.• Plants – Tall, perennial grasses – Drought tolerant and fire resistant trees & shrubs
  • 5. Tropical Savanna, cont.• Animals – Predators: lions, leopards, cheetahs, hyenas, jackals, aardvarks – Herbivores: elephants, giraffes, antelope, zebras, baboons – Birds: eagles, ostriches, storks – Reptiles: none – Insects: termites
  • 6. Tropical Savanna, cont.• Location – East Africa – Southern Brazil – Northern Australia
  • 7. Desert• Abiotic – Low precipitation – Variable temperatures – Soils rich in minerals but poor in organic material
  • 8. Desert, cont.• Plants – Cacti – Succulents – Creosote bush – Plants with short growth cycles
  • 9. Desert, cont.• Animals – Predators: mountain lions, gray foxes, bobcats – Herbivores: mule deer, pronghorn antelope, bighorn sheep, kangaroo rats, bats – Birds: owls, hawks, roadrunners – Reptiles: tortoises, rattlesnakes, lizards – Insects: ants, beetles, butterflies, flies, wasps
  • 10. Deserts, cont• Location – Africa – Asia – Middle east – South America – Australia
  • 11. Temperate Grassland• Abiotic – Warm to hot summers – Cold winters – Moderate seasonal precipitation – Fertile soil – Occasional fires
  • 12. Temperate Grassland, cont.• Plants – Lush perennial grasses and herbs
  • 13. Temperate Grassland, cont.• Animals – Predators: coyotes, badgers – Herbivores: mule deer, pronghorn antelope, rabbits, prairie dogs; formerly had bison – Birds: owls, hawks, bobwhite, prairie chickens – Reptiles: snakes – Insects: grasshoppers, ants
  • 14. Temperate Grassland, cont.• Location – South Asia – North America – Australia – Central Europe – South America
  • 15. Tropical Rain Forest• Abiotic – Hot and wet year round – Thin, nutrient-poor soil
  • 16. Tropical Rain Forest, cont.• Plants – Broad-leaf evergreen – Ferns – Large woody vines – Orchids – Bromeliads
  • 17. Tropical Rain Forest, cont.• Animals – Predators: jaguars, anteaters, monkeys – Herbivores: sloth, tapirs – Birds: toucans, parrots, parakeets – Reptiles: Caymans, boa constrictors, anaconda – Insects: butterflies, ants, beetles – Fish: piranhas
  • 18. Tropical Rain Forest, cont.• Location – South and Central America – Southeast Asia – Parts of Africa – Southern India – Northeast Australia
  • 19. Savanna• Abiotic – Generally warm year round – Alternating wet-dry seasons – Rich soils, easily eroded
  • 20. Savanna, cont.• Plants – Tall, deciduous trees – Orchids – Bromeliads – Aloes – Succulents
  • 21. Savanna, cont.• Animals – Predators: tigers, monkeys – Herbivores: elephants, Indian rhinocerous, hog deer – Birds: pelican, great pied hornbill, pied harrier – Reptiles: snakes, lizards – Insects: termites
  • 22. Savanna, cont.• Location – Parts of Africa – Southern & Central America – Mexico – India – Australia – Tropical Islands
  • 23. Temperate Forest• Abiotic – Cold to moderate winters – Warm summers – Year round precipitation – Fertile soils
  • 24. Temperate Forest, cont.• Plants – Broadleaf deciduous trees – Conifers – Flowering shrubs – Herbs – Ground layer of mosses and ferns
  • 25. Temperate Forest, cont.• Animals – Predators: black bear, bobcats – Herbivores: deer, squirrels, raccoons, skunks – Birds: songbirds, turkeys – Reptiles: – Insects: beetles
  • 26. Temperate Forest, cont.• Location – Eastern United States – Southeast Canada – Europe – Japan – China – Australia
  • 27. Tundra• Abiotic – Strong winds – Low precipitation – Short summers – Cold, dark winters – Poorly developed soils – Permafrost
  • 28. Tundra, cont.• Plants – Mosses – Lichens – Low-lying grasses
  • 29. Tundra, cont.• Animals – Migratory waterfowl – Shore birds – Musk ox – Arctic foxes – Caribou – Small rodents
  • 30. Tundra, cont.• Location – North America – Asia – Europe
