Study Notes
Biomes of North America
- The tundra is recognized as the coldest biome in North America.
- The desert is the hottest biome, characterized by extremely high temperatures and low precipitation.
- Tropical rainforests receive the most rainfall among the biomes.
Rainfall and Temperature Relationships
- Coniferous forests experience low temperatures and minimal rainfall.
- Tropical rainforests have the highest temperatures and rainfall.
- Generally, higher rainfall correlates with higher temperatures, while lower rainfall correlates with lower temperatures.
Temperature Similarities Among Biomes
- Grasslands and deciduous forests maintain similar average temperatures.
Types of Forests
- Three distinct forest types in North America include:
- Coniferous Forest (Taiga)
- Temperate Deciduous Forest
- Tropical Rainforest
Biodiversity and Equatorial Proximity
- Proximity to the equator significantly increases species diversity within a biome.
Major North American Biomes
- North America consists of six primary biomes:
- Tundra
- Desert
- Deciduous Forest
- Coniferous Forest
- Grasslands
- Tropical Rainforest
Latitude and Biodiversity
- Biodiversity is affected by latitude:
- Higher latitudes tend to be colder.
- Lower latitudes are typically warmer, with regions closer to the equator receiving abundant sunlight.
Ecological Succession Definitions
- Primary Succession: Occurs on new substrates without soil, such as volcanic ash or glacial deposits; pioneer plants create new soil.
- Secondary Succession: Involves changes in an existing ecosystem following a disturbance, preserving some soil.
- Pioneer Community: The initial collection of organisms, including plants, animals, and decomposers, establishing in an area undergoing primary succession.
- Seral Stage: Any community that occurs between the pioneer and the climax communities.
- Climax Community: The stable end point of ecological succession, representing a mature ecosystem.
Human Impact on Succession
- Deflected Succession: Occurs when human actions alter the natural progression of ecological succession, preventing the development of a climatic climax community.
- Plagioclimax: A human-influenced community that disrupts the natural climax community from being formed.
