Study Notes
Biomes
- Biome definition: A distinct physical environment with ecologically similar organisms having similar adaptations. Biomes are often characterized by the dominant type of vegetation.
Factors Determining a Biome
- Physical environment: Soils, natural or human-induced disturbances (e.g., fire, grazing).
- Climate and climatic variability: Temperature, precipitation, and seasonality are crucial.
Global Climate Patterns and Biomes
- Global climate patterns strongly influence biome distribution. These patterns link to major wind systems and precipitation patterns.
Key Drivers: Temperature and Precipitation
- Average temperature and precipitation levels influence biome types. The interplay of these factors determines the dominant life forms, such as forests, grasslands, or deserts. Climate diagrams (Walter climate diagrams) are valuable tools for biome analysis; they display temperature and precipitation patterns over the year.
Walter Climate Diagrams
- These diagrams illustrate temperature and precipitation patterns.
- The temperature line (red) and precipitation line (blue) on a Walter climate diagram are vital indicators of water availability
- Ecosystem water limitations arise when precipitation lines are lower than the temperature lines.
- The x-axis usually represents months, starting in January in the Northern hemisphere and July in the Southern hemisphere. The y-axis displays temperature (degrees Celsius) and precipitation (millimeters).
- White-colored areas denote frozen conditions and are inhospitable to most life.
- Effective growing season occurs where temperature remains above 0°C.
Specific Biomes
- Tropical Rain Forest: High rainfall, stable temperatures, extremely biodiverse.
- Desert: Low precipitation, varying temperatures (hot or cold). Plants are adapted to conserve water. Animals concentrate urine.
- Tundra: Cold, very low temperatures with brief, cold summers; little rainfall. Plants are low growing (e.g., cushion plants, lichens, moss), often have anti-freeze proteins.
- Boreal Forest (Taiga): Long, cold winters; significant precipitation that falls as snow. Soils are generally poor, but have an abundance of conifer trees.
- Temperate Forest: Distinct winter season with frost and snow; summer usually moist; fertile soils.
- Temperate Grassland/Shrubland: Hot summers and cold winters; few trees; dominated by grasses. May become forests if precipitation increases.
- Tropical Savanna/Seasonal Forest: Temperature varies little; characteristic of distinct wet/dry seasons, and tree/grass codominance. Often requires disturbance to maintain diverse structures.
General Biome Summary
- Distributions of various biomes are shown on maps demonstrating their geographic prevalence. Key environmental factors (temperature & precipitation) determine biome types. Adaptations of organisms reflect the needs associated with particular biomes.
