8Tundra Temperature: Cold Precipitation: Low Growing season: Short – 4 monthsVegetation: small shrubs, mosses, lichensAdaptations: can grow in shallow waterlogged soil, survive short growing seasons and coldSoil nutrient level: LowPermafrost: impermeable, permanently frozen layer, prevents H20 from draining and roots from penetrating (no trees)Why does tundra have nutrient poor soil? Cold temperatures slow decomposition rates
9Boreal Forest Temperature: Precipitation: Growing season: Vegetation: Adaptations:Like the tundra, the boreal forest has nutrient poor soil. Why?
10Boreal Forest Temperature: Cold Precipitation: Low Growing season: ShortVegetation: Coniferous and deciduousAdaptations: Coniferous needles tolerate cold, deciduous drop leaves before coldLike the tundra, the boreal forest has nutrient poor soil. Why?Soils are nutrient poor so poorly suited for agriculture but important source of lumber
12Temperate Rain Forest Temperature: Moderate Precipitation: High Growing season: Long – 12 monthsVegetation: very large trees – fir, spruce, redwoodsSoil nutrient level: Low – due to coniferous needles that are slow to decomposeLocation: Coastal – oceans moderate temperature and provide water vaporThreats: Large trees are loggedNutrient poor soil due to coniferous needles that are slow to decompose – nutrients rapidly taken up or leached down through the soil
16Woodland/Shrubland Temperature: hot summer and mild winter Precipitation: dry summer and rainy winterGrowing season: 12 month – constrained by low rain in summer and low temps. in winterVegetation: yucca, scrub oak, sagebrushSoil nutrient level: Low – leaching by winter rainsAdaptations: plants adapted to fire and drought – seeds open after intense heat, plants resprout quickly after fire
17Temperate Grassland (Prairie, Steppes, Pampas) Temperature:Precipitation:Growing season:Vegetation:Soil Nutrient Level:Adaptations:Tall grass prairie vs. short grass prairie vs. cold desert
18Temperate Grassland (Prairie, Steppes, Pampas) Temperature: Cold winter, hot summersPrecipitation: Dry summersGrowing season: 12 month – constrained by low rain in summer and low temps. in winterVegetation: grasses and non woody flowering plantsSoil Nutrient Level: Rapid decomp. makes this biome very productiveAdaptations: wildfires and frequent grazing – deep roots store energy for quick regrowthTall grass prairie vs. short grass prairie vs. cold desert98% of tall grass prairie in the united states has been converted to agriculture
19Tropical Rainforest Temperature: Precipitation: Growing season: Vegetation:Soil Nutrient Level:Canopy vs. understoryEpiphytes and lianas
20Tropical Rainforest Temperature: High Precipitation: High Growing season: 12 monthsVegetation: More biodiversity than any other biomeSoil Nutrient Level: Warm and wet – rapid decomp. but nutrients are taken up quicklyCanopy vs. understoryEpiphytes and lianas
22Tropical Seasonal Forest Temperature: WarmPrecipitation: Wet and dry seasonsGrowing season: Long – but limited by rainVegetation: deciduous trees and grassesSoil Nutrient Level: Warm temps. allow rapid decomp. - fertile soilsAdaptations: drop leaves during dry season
24Desert Temperature: Hot Precipitation: Dry Growing season: Short – limited by rainVegetation: sparse vegetationAdaptations: small, thick waxy layer with few pores to conserve water. Spines to protect themselves from herbivores
