Not too hot, not too cold
- Every species can survive only within certain conditions.
- Too hot or too cold, too salty or too dry, and it cannot live.
- This range of survivable conditions is its ecological tolerance.
- Where a species lives depends on staying inside that range.
不太热,不太冷
- 每个物种都只能在某些条件内生存。
- 太热或太冷、太咸或太干,它就无法生活。
- 这个可生存的条件范围就是它的生态耐受性。
- 一个物种生活在哪里,取决于是否留在那个范围内。
The optimum range
- Ecological tolerance 生态耐受性 is the range of conditions a species can survive.
- In the middle is the optimum range 最适范围, where conditions are ideal.
- Here the population thrives and grows fastest.
- This is where you find the most of that species.
最适范围
- 生态耐受性(ecological tolerance)是一个物种能生存的条件范围。
- 中间是最适范围(optimum range),那里条件理想。
- 在这里种群繁盛、增长最快。
- 这是你找到那个物种最多的地方。
Ecological tolerance is… · 生态耐受性是……
Ecological tolerance is the range of conditions (like temperature) a species can survive. · 生态耐受性是一个物种能生存的条件范围(比如温度)。
Zones of stress
- Move away from the optimum and conditions get harder.
- In the zone of stress, individuals survive but struggle.
- They grow slower and reproduce less.
- Fewer of the species live in these tougher zones.
胁迫区
- 离开最适,条件就变得更艰难。
- 在胁迫区里,个体存活但很挣扎。
- 它们生长得更慢、繁殖得更少。
- 在这些更艰难的区域里,这个物种的数量更少。
Zones of tolerance · 耐受的各个区域
Step from the ideal centre out to the edges - a species thrives, then struggles, then cannot survive. · 从理想的中心走到边缘——一个物种繁盛,然后挣扎,然后无法生存。
Where does a population do best? · 一个种群在哪里表现最好?
A species thrives in its optimum range, where conditions are ideal. · 一个物种在它的最适范围繁盛,那里条件理想。
Outside its ____ range, a species cannot survive. · 在它的____范围之外,一个物种无法生存。
Beyond the tolerance range, conditions are too extreme and the species dies out there. · 在耐受范围之外,条件太极端,这个物种在那里灭绝。
Beyond the limits
- Near the edges of the range, conditions become too extreme.
- Past the limits of the tolerance range 耐受范围, the species cannot survive.
- It is simply absent from those places.
- So tolerance sets the boundary of where a species can live.
超出极限
- 接近范围的边缘,条件变得太极端。
- 越过耐受范围(tolerance range)的极限,这个物种无法生存。
- 它在那些地方就是缺席。
- 所以耐受性设定了一个物种能生活的边界。
A species with a narrow tolerance range is more vulnerable to environmental change. · 一个耐受范围窄的物种对环境变化更脆弱。
Narrow tolerance means even a small change can push conditions past what the species can survive. · 窄的耐受意味着即使一个小变化也能把条件推过这个物种能生存的范围。
Select all · 所有 true statements about ecological tolerance. · 选出关于生态耐受性的所有正确说法。
No species tolerates every condition — each has limits. The other three are correct. · 没有物种能耐受每一种条件——每个都有极限。其余三条正确。
A species with a narrow tolerance range is far more at risk. If it can only survive a small band of temperatures, even a small warming can push conditions past its limit. Wide-tolerance species cope with change; narrow-tolerance species can be wiped out.
一个耐受范围窄的物种风险大得多。如果它只能生存一小段温度,即使一个小的变暖也能把条件推过它的极限。宽耐受的物种能应对变化;窄耐受的物种可能被消灭。
Coral and warming seas:
- Corals have a narrow temperature tolerance.
- Their optimum is a fairly small band of warm water.
- Even a couple of degrees of ocean warming pushes many reefs past their limit, causing them to bleach and die — a narrow tolerance meeting a changing climate.
珊瑚与变暖的海:
- 珊瑚有一个窄的温度耐受性。
- 它们的最适是相当小的一段温暖的水。
- 即使海洋变暖几度,也会把许多珊瑚礁推过它们的极限,使它们白化并死亡——窄的耐受遇上变化的气候。
Ecological tolerance is the range of conditions a species can survive. It thrives in its optimum range, struggles in the zones of stress toward the edges, and cannot survive beyond its tolerance range. Species with a narrow tolerance are especially vulnerable to environmental change.
生态耐受性是一个物种能生存的条件范围。它在它的最适范围繁盛,在朝边缘的胁迫区里挣扎,在它的耐受范围之外无法生存。耐受范围窄的物种对环境变化尤其脆弱。
