<The Long-Term Stability of Ecosystems>
[문단정리]
1문단
#Communities 1) pioneer 2) climax
succession : refer to change
-> 1) pioneer = successional plant communities
- first
- change over periods from 1 to 500 years
->changes in plant numbers and the mix of species are cumulative
2) climax
- the long-lived community at the end of succession
- change but over period of time greater than about 500 years
2문단
#Ecosystem
Ecologist may end it relatively unchanged in year’s time.
생태학자는 일년이 지나면 연못을 상대적으로 변화지 않은 상태로서 끝마칠 것이다.
individual fish = change
the number of fish = same from one year to the next
∴ properties of ecosystem are more stable than the nay individual organism
3문단
#Diversity
At one time -> Not now : diversity made ecosystems stable
support -> long-lasting climax communities more complex and diversity than pioneer
stability depend on their complexity
ex) single crop farmlands -> unstable -> destroy the entire crop
<-> complex climax community will tolerate damage
4문단
#Stability
ecologist do not all agree what “stability” means
stability can be defined as simply lack of change -> climax community : the most stable
stability can be defined as the speed -> resilience -> climax community : the most fragile
5문단
#Diversify -> climax(complicated system) -> the most stability (x) -> simple system (o)
Maximum diversity is often found -> mid-successional stages
diversity does not ensure stability -> just the opposite : 다양성은 안정성을 보장하지 않는다 -> 사실상 (일반적으로) 단일성이 안정성을 보장할 수 있다. : simple system -> child’s tricycle
6문단
#Factors
destruction : 자연 <<<<<<< … <<< 인간
7문단
#Patchiness
Organism and Environment : varies from place to place > uniform
A local population is replaced by immigrants the new population can fill the niche(a local population goes extinct) and keep the food web intact.
