    Study Notes

    Climate and Biomes

    • Climate refers to long-term averages of weather conditions including temperature, humidity, and precipitation, crucial for understanding ecosystems.
    • Abiotic factors like temperature, wind, and rain significantly influence the characteristics of biomes, such as desert and rainforest formations.

    Terrestrial Biomes

    • A biome is a collection of similar ecosystems defined by shared abiotic factors and primary producers.
    • Major terrestrial biomes include tundras, temperate forests, grasslands, chaparral, temperate and tropical deserts, and tropical forests.

    Climate Characteristics

    • Climate is defined as the average weather over time, while weather focuses on short-term conditions.
    • Temperature gradients exist from the equator (hot) to the poles (cold), categorized into tropical, temperate, and arctic zones.
    • Coastal regions experience moderate temperatures due to water's slow heat absorption and release, contrasting with inland areas.

    Moisture and Precipitation

    • Climates are classified based on moisture levels: arid (dry), semi-arid, humid (wet), and semi-humid.
    • Factors affecting precipitation include air mass movement, temperature (warm air holds more moisture), and geographical features like mountains.
    • Rain shadows occur when moist air rises over mountains, cools, and loses moisture, leading to dry conditions on the leeward side.

    Plant Growth and Climate

    • Plants, the primary producers in biomes, require air, warmth, sunlight, water, and nutrients, all influenced by climate.
    • The growing season varies from year-round in tropical climates to just a few months in colder or drier regions.
    • Soils rich in nutrients are ideal for plant growth, but decomposition rates differ across climates, affecting soil quality.

    Biodiversity

    • Biodiversity tends to increase from polar to equatorial regions and is generally higher in humid climates.
    • The disparity between desert and rainforest biomes exemplifies how climate impacts the diversity of life forms within terrestrial biomes.

    Organism Adaptations

    • Species evolve specialized adaptations for survival in their respective climates; desert plants may store water, while cold-climate species might undergo dormancy.
    • Examples of adaptations include:
      • Aloe and cactus storing water in specialized tissues.
      • Gila monsters storing water in their fat tails.
      • Kangaroo rats with efficient kidneys to minimize water loss.
      • Polar bears using thick fur and blubber for insulation against cold.

    Summary of Climate Influence

    • The climate determines key ecological aspects like plant growth, biodiversity, and organism adaptations in terrestrial biomes, illustrating the interconnectedness of environmental factors and living organisms.
