|
What is the role of ecological diversity and how does it affect productivity and stability?
|
Productivity - NPP; amount of plant material available to herbivores and decomposers
Stability - Two measures; resistance - measure of how much a disturbance affects a community; resilience - measure of how quickly a community recovers from disturbance |
|
|
What view does Gleason have on community?
|
Collection of individual species w. unique physiological tolerances
Individualistic view of community dynamics |
|
|
What view does Clements have on community?
|
Saw communities as superorganisms
Species worked cooperatively |
|
|
What is succession? What is the difference between primary and secondary succession?
|
The recovery of a community after a disturbance
Primary - all species left + soil removed - ex lava flow and glaciers Secondary - all species + soil removed - ex fire and strong storm |
|
|
What is early vs late vs climax successional communities?
|
Early - pioneer (high dispersal, fast growing, short-lived)
Late - long lived, slow growing, superior competitors Climax - stable persistent community |
|
|
What are the three species interactions during succession: facilitation, inhibition, tolerance?
|
Facilitation - one species makes it more tolerable for another
Inhibition - one species prevents the establishment of another Tolerance |
|
|
What are ecosystems? What are the four basic components? What is the difference of the flow of energy vs matter?
|
Groups of communities + chem and phys environment
Abiotic, producers, consumers, and decomposers Matter cycles, energy flows |
