Term
| name the macroscale drivers of vegetation communities: |
|
Definition
| global climate (including global wind patterns and global climate change) and physiograpy |
|
|
Term
|
Definition
| Climate is the long-term weather of a certain place on earth. It is determined by air temperature and precipitation. |
|
|
Term
| name the two most important factors that determine climate: |
|
Definition
| air temperature and precipitation |
|
|
Term
|
Definition
| Physiography is the physical features of the earth's surface. |
|
|
Term
| name some of the factors contributing to clumping of species across a landscape: |
|
Definition
-dispersal of seed
-reproduction
-variations in the environment |
|
|
Term
| name the seven main vegetation communities of North America: |
|
Definition
1-Boreal/Taiga
2-Rocky Mountain
3-Pacific Coast
4-Southwest Interior
5-Pine-Hardwood
6-Central Hardwood
7-Northern Hardwood |
|
|
Term
| name the microscale drivers of vegetation communities: |
|
Definition
-soils
-local physiography (elevation, aspect, slope, topography)
-natural range
-succession
-disturbance
-biota
-humans
|
|
|
Term
| name the four factors of local physiography: |
|
Definition
| elevation, aspect, slope, topography |
|
|
Term
|
Definition
| Natural range is where conditions are suitable for growth of a species. |
|
|
Term
|
Definition
| Succession is the gradual subplanting of one community of plants by another. |
|
|
Term
| define the role of disturbance in plant succession: |
|
Definition
| Disturbance influences which plants grow in an area because plants are often adapted to disturbance regimes in an area. |
|
|
Term
| describe how biota impacts succession and vegetation communities: |
|
Definition
| Biota can include other species that compete for a habitat. Some biota, such as invasive species, can prevent succession by completely dominating a habitat. |
