迁地保护和就地保护有什么不同？
How does ex-situ differ from in-situ conservation?
就地保护在原栖息地建立自然保护区维持生态过程；迁地保护把物种移入动物园、植物园或种子库等人工环境作为备份，二者互为补充。
In-situ conservation protects species in their natural habitat and ecological context; ex-situ moves them to zoos, botanic gardens or seed banks as a backup—the two complement each other.

为什么一个物种的灭绝，有时比它彻底消失更值得警惕？
Why can a species' functional extinction be more alarming than its total disappearance?
功能性灭绝指物种数量已低到无法在生态中发挥原有作用（如不再传粉、不再被捕食），即使个体尚存，食物链和生态功能已经受损，预警意义更早也更关键。
Functional extinction means numbers are too low for a species to play its ecological role (no longer pollinating or preyed upon); even with individuals alive, food webs and functions are already damaged, giving an earlier and crucial warning.

把宠物鳄龟、清道夫鱼放生到野外，为什么反而成灾？
Why does releasing pet turtles or catfish into the wild become a disaster?
这些外来种在新环境往往缺乏天敌、适应力强且食性广，会挤占本土物种的生存空间和食物，破坏当地食物链与生态。
Such exotics often lack local predators and are broadly adapted and voracious, outcompeting natives for space and food and disrupting local food webs.

城市里种本地花草，为什么比种外来观赏植物更利于生态？
Why are native flowers and grasses better for urban ecology than exotic ornamentals?
本地植物与当地的昆虫、传粉者和鸟类协同演化，更能支撑本土食物链和传粉网络；外来观赏种常无法给本地生物提供合适的食物或栖息地。
Native plants co-evolved with local insects, pollinators and birds, better supporting regional food webs and pollination; exotic ornamentals often fail to provide suitable food or habitat.

什么是公民科学，普通人怎么参与生物保护？
What is citizen science, and how can ordinary people help conservation?
公民科学让公众参与记录物种分布、参与鸟类普查和入侵种监测，积累的数据能帮科学家追踪变化、制定保护策略。
Citizen science engages the public in recording species, bird counts and invasive monitoring; the data help scientists track changes and shape conservation.

大熊猫从濒危降为易危，为什么算保护成功？
Why is the giant panda's downlisting from Endangered to Vulnerable seen as a success?
数十年栖息地恢复与人工繁育使野生种群回升、分布区扩大；但栖息地碎片化和低繁殖率仍是长期挑战，降级不代表可以松懈。
Decades of habitat recovery and captive breeding raised wild numbers and range; but habitat fragmentation and low reproductive rate remain long-term challenges, so downlisting is not a reason to relax.

朱鹮曾全世界只剩7只，后来怎么又飞回了中国的天空？
The crested ibis dropped to just 7 birds worldwide—how did it return to China's skies?
1981年在陕西洋县重新发现仅存的7只野生朱鹮后，中国建立保护区、禁止农药、人工繁育并补食，逐步扩大到野化放飞，如今种群已恢复到数千只。
After the last 7 wild ibis were found in Yang County, Shaanxi in 1981, China set up reserves, banned pesticides, bred them in captivity and supplemented feeding, later releasing them. The population has recovered to thousands.

保护生物多样性，对人类自己有什么好处？
How does conserving biodiversity benefit humans themselves?
生物多样性支撑授粉、净水、土壤形成和气候调节等生态系统服务，是人类粮食、药物和清洁环境的根基，失去它代价极高。
Biodiversity underpins ecosystem services like pollination, clean water, soil formation and climate regulation—the foundation of our food, medicine and clean environment.

濒危物种红色名录是做什么用的？
What is the IUCN Red List for?
世界自然保护联盟依据种群趋势和威胁程度评估物种灭绝风险并分级（如极危、濒危、易危），帮助政府和公众确定保护的优先次序。
The IUCN assesses extinction risk from population trends and threats, ranking species (e.g. Critically Endangered, Endangered, Vulnerable) to guide conservation priorities.
