Study Notes
Biomes Overview
- Biomes are broad categories of ecosystems sharing common traits.
- Major examples include Desert, Rainforest, and Tundra.
- Biome identity is largely determined by plant species and climate.
Climate Influence on Biomes
- Climate is the primary factor affecting the location of biomes.
- Key climate influencers:
- Latitude affects energy input and sun angle.
- Continental Position shapes climate through land and sea interaction.
- Altitude impacts temperature due to adiabatic cooling.
- Orographic Effect changes precipitation patterns based on geography.
Soil Characteristics
- Soil is a complex mixture impacting biomes, composed of living and non-living materials.
- Influencing factors include local geology, climate, and the biotic community.
- Soil classification is based on horizons:
- O horizon: Organic material layer.
- A horizon: Mixture of minerals and organic matter.
- B horizon: Clay and leached materials containing plant roots.
- C horizon: Weathered parent material.
Tropical Rainforest
- Found within 20° latitude of the equator.
- Experiences little temperature fluctuation and receives 2,000 - 4,000 mm of rainfall annually.
- Rapid soil nutrient leaching occurs; mycorrhizae assist in nutrient acquisition.
- Heightened biodiversity with arboreal animals and diverse insect populations.
Tropical Dry Forest
- Located between 10° and 25° latitude, seasonal climate with richer soils than rainforests.
- Subject to deforestation for agriculture.
- Shares flora and fauna with tropical rainforests.
Tropical Savanna
- Positioned within 10° to 20° latitude with wet and dry seasonal alternation.
- Drought conditions lead to wildfires; soils have low water retention.
- Characterized by two-dimensional landscapes due to livestock pressures.
Desert Biome
- Predominant at 30° N and 30° S latitude, covering 20% of Earth's land.
- Water loss exceeds precipitation; soils retain low organic matter.
- Low animal abundance with high biodiversity due to adaptive behaviors.
Chaparral Biome
- Found in Mediterranean climates across all continents except Antarctica.
- Cool and moist off-seasons with hot, dry summers.
- Soil is fragile yet moderately fertile; vegetation includes fire-resistant plants.
Temperate Grassland
- Extensively distributed with annual rainfall between 300 - 1,000 mm.
- Experiences periodic droughts; soils are nutrient-rich and deep.
- Dominated by herbaceous plants; large grazing animals common, e.g., bison and cattle.
Temperate Forest (Old Growth)
- Majority located between 40° and 50° latitude with rainfall of 650 - 3,000 mm.
- Fertile soils promote long growing seasons dominated by deciduous and coniferous plants.
Boreal Forest (Taiga)
- Restricted to the Northern Hemisphere, covering 11% of Earth's land area.
- Features thin, acidic soils with low fertility and is dominated by evergreen conifers.
- Relatively high density of animal populations.
