|
|
First species to colonize an area after a disturbance |
Pioneer species |
|
|
No previous life existing Pioneer species Starts on bare rock Happens slow |
Primary succession |
|
|
Start as a result of a forest fire or flood Previously existing life Starts with previously existing soil Happens fast |
Secondary |
|
|
Two or more species use the same limited resource |
Competition |
|
|
Used to describe a situation in which one species is eliminated from a community because ofcompetition |
Competitive exclusion |
|
|
A species avoid competition with each other by using only a specific part of an available resource |
Resource partitioning |
|
|
Number of different species in a community |
Species richness |
|
|
All organisms have differences that result from differences in their genetic material |
Variation |
|
|
Organisms generally produce more offspring than can survive |
Overproduction |
|
|
Some variations all an individual to survive better than other individuals |
Adaptation |
|
|
Beneficial variations will be passed on more frequently and will become common |
Decent with modification |
|
|
Observable change in the allele frequencies of a population over time |
Microevolution |
