The variety of life
- A rainforest teems with thousands of species; a car park has almost none.
- This variety of life is what we call biodiversity.
- More variety usually means a healthier, stronger ecosystem.
- Protecting it is one of biology's biggest challenges.
生命的多样性
- 一片雨林充满着成千上万个物种;一个停车场几乎没有。
- 这种生命的多样性,就是我们所说的生物多样性。
- 更多的多样性通常意味着一个更健康、更强壮的生态系统。
- 保护它是生物学最大的挑战之一。
What biodiversity is
- Biodiversity 生物多样性 is the variety of living things in an area.
- It counts the number of different species and how even their numbers are.
- It also includes variety of genes and of whole ecosystems.
- A place rich in species has high biodiversity.
什么是生物多样性
- 生物多样性(biodiversity)是一个区域里生物的多样性。
- 它数不同物种的数量,以及它们的数量有多均匀。
- 它也包括基因和整个生态系统的多样性。
- 一个物种丰富的地方有高生物多样性。
Biodiversity · 生物多样性 is… · 生物多样性是……
Biodiversity · 生物多样性 is the variety of species (and genes and ecosystems) in an area. · 生物多样性是一个区域里物种(以及基因和生态系统)的多样性。
Why it matters
- High biodiversity makes an ecosystem 生态系统 more stable and resilient.
- If one species is lost, others can often fill its role.
- Diverse ecosystems also give us food, medicines, and clean air and water.
- A biodiverse world is more able to survive change.
它为什么重要
- 高生物多样性让一个生态系统(ecosystem)更稳定、更有韧性。
- 如果失去一个物种,其他的常常能填补它的角色。
- 多样的生态系统还给我们食物、药物,以及干净的空气和水。
- 一个生物多样的世界更能在变化中生存。
Why does high biodiversity help an ecosystem? · 高生物多样性为什么对一个生态系统有帮助?
High biodiversity makes an ecosystem more stable — if one species is lost, others can fill the gap. · 高生物多样性让一个生态系统更稳定——如果失去一个物种,其他的能填补空缺。
A species that has an especially large effect on its community is a ____ species. · 一个对它的群落有特别大影响的物种是一个____种。
A keystone species holds the community together; losing it can collapse the whole ecosystem. · 关键种把群落维系在一起;失去它可能让整个生态系统崩溃。
Keystone species
- Some species matter far more than their numbers suggest.
- A keystone species 关键种 holds its whole community together.
- Remove it, and the ecosystem can collapse.
- Threats like habitat loss, pollution, and climate change all reduce biodiversity.
关键种
- 有些物种的重要性远超它们的数量所暗示的。
- 一个关键种(keystone species)把它整个群落维系在一起。
- 移除它,生态系统就可能崩溃。
- 栖息地丧失、污染和气候变化这类威胁都减少生物多样性。
High or low biodiversity? · 高还是低生物多样性?
Sort each place by how much variety of life it holds - high or low biodiversity. · 按照每个地方容纳多少生命的多样性——高还是低生物多样性——给它们分类。
Habitat loss and pollution are threats that can reduce biodiversity. · 栖息地丧失和污染是能减少生物多样性的威胁。
Habitat loss, pollution, and climate change all reduce biodiversity by wiping out species. · 栖息地丧失、污染和气候变化都通过消灭物种来减少生物多样性。
Select all · 所有 true statements about biodiversity. · 选出关于生物多样性的所有正确说法。
A car park has low · 低 biodiversity — almost no species. The other three are correct. · 停车场有低生物多样性——几乎没有物种。其余三条正确。
Biodiversity is not just a "nice to have". High biodiversity makes an ecosystem more stable — able to recover from disease, weather, or the loss of a species. A low-biodiversity system, like a single-crop field, is fragile: one pest can wipe out everything.
生物多样性不只是"锦上添花"。高生物多样性让一个生态系统更稳定——能从疾病、天气或一个物种的丧失中恢复。一个低生物多样性的系统,像一块单一作物的田地,是脆弱的:一种害虫就能把一切消灭。
The sea otter, a keystone species:
- Sea otters eat sea urchins, which would otherwise devour the kelp forests.
- Remove the otters, and urchins explode and strip the kelp bare.
- The whole community — fish, seals, and more — collapses. A single keystone species held it all together.
海獭,一个关键种:
- 海獭吃海胆,否则海胆会吞食海带林。
- 移除海獭,海胆就爆发,把海带啃得精光。
- 整个群落——鱼、海豹等等——都崩溃。一个单一的关键种把这一切维系在一起。
Biodiversity is the variety of living things in an area. High biodiversity makes an ecosystem more stable and resilient, and supplies food, medicine, and clean air. A keystone species has an outsized effect — losing it can collapse a community. Habitat loss, pollution, and climate change all threaten biodiversity.
生物多样性是一个区域里生物的多样性。高生物多样性让一个生态系统更稳定、更有韧性,并提供食物、药物和干净的空气。一个关键种有着超乎寻常的影响——失去它可能让一个群落崩溃。栖息地丧失、污染和气候变化都威胁着生物多样性。
