Terrestrial Biomes Summary

Major Types of Terrestrial Biomes:

  • Tropical Rainforest

  • Temperate Forest

  • Taiga (Boreal Forest)

  • Desert (Hot & Dry, Semi-Arid, Coastal, Cold)

  • Grassland (Tropical and Temperate)

  • Chaparral

  • Tundra (Arctic and Alpine)

Tropical Rainforest

  • Location: Near the equator, hot and moist.

  • Climate: Temperatures 20-34°C, annual precipitation 125-660 cm.

  • Soil: Nutrient-deficit, mainly Oxisol and Utisol.

  • Layers: 1. Emergent 2. Canopy 3. Understory 4. Forest Floor.

  • Flora: High biodiversity, includes epiphytes, carnivorous plants.

  • Fauna: Rich in insects, birds, mammals like chimpanzees, large animals on the forest floor.

Temperate Forest

  • Location: Distinct seasons in temperature and precipitation.

  • Climate: 10°C in winter, 21°C in summer, 75-150 cm precipitation.

  • Soil: Fertile alfisols.

  • Flora: Deciduous trees, shrubs, diverse herb layers.

  • Fauna: Hibernation and migration strategies in bears, deer, foxes, etc.

Taiga (Boreal Forest)

  • Location: Northern circumpolar regions.

  • Climate: -10°C to few degrees above freezing, precipitation 30-50 cm.

  • Soil: Highly acidic spodosols.

  • Flora: Dominated by cone-bearing trees like spruces and pines.

  • Fauna: Adapted to cold; includes snowshoe hares and lynx.

Desert Biome

  • Classification: Hot & Dry, Semi-Arid, Coastal, Cold.

  • Hot & Dry: 29-46°C daytime temps, precipitation < 1.5 cm.

  • Semi-Arid: Moderate summer temperatures, precipitation 2-4 cm, similar fauna.

  • Coastal: Milder climate, summer temps 13-24°C, specialized flora.

  • Cold Desert: Long cold winters, short summers, diverse small mammals and reptiles.

Grassland Biome

  • Characteristic: Large areas of grass, flowers, and herbs.

  • Tropical: High temp (20-30°C), precipitation 50.8-127 cm, home to giraffes and cheetahs.

  • Temperate: Includes prairie (tall grasses) and steppe (short grasses).

Chaparral

  • Climate: Mild winters (10-12°C) and hot, dry summers.

  • Soil: Thin, rocky, nutrient-poor, prone to erosion.

  • Flora: Scrubby vegetation, drought-resistant plants like Yucca.

  • Fauna: Adapted to hot climates; includes night-active animals.

Tundra

  • Classification: Arctic and Alpine.

  • Arctic: Extremely cold; summer temps up to 12°C.

  • Alpine: Cold climate, flora adapted to harsh conditions, migratory fauna.

  • Soil: Permafrost in Arctic, specialized requirements for plant survival.

Summary

Terrestrial biomes have distinct climate, soil types, flora, and fauna that adapt to their environments. Overall, they are crucial ecosystems that support a wide variety of life forms and have significant impacts on global biodiversity and climate regulation.
