物种的生态位是什么概念？
What is the concept of a species' ecological niche?
生态位描述物种在环境中如何生存和繁衍，包括它利用的资源、活动时间和与其他物种的关系，而不只是地理分布。哈钦森将其定义为物种能够存活繁殖的多维环境空间。竞争排斥原理指出两个物种难以长期占据完全相同的生态位。
A niche describes how a species survives and reproduces, including the resources it uses, its timing and its relationships with other species, not merely its geographic range. Hutchinson defined it as the multidimensional environment space in which a species can persist. The competitive exclusion principle says two species cannot occupy the same niche indefinitely.

生境破碎化的危害为什么不能只用面积损失来衡量？
Why can't the harm of habitat fragmentation be measured by area loss alone?
破碎化在同等面积下改变了空间格局：斑块变小使种群规模低于最小存活阈值，边缘比例上升带来光照、湿度和风的改变以及捕食者与入侵植物入侵，斑块间隔离则阻断扩散和基因交流。长期实验表明，破碎化的负面效应会随时间累积，物种数在数十年内继续衰减，出现所谓灭绝债务。因此保护规划必须同时考虑面积、形状、连通性与基质质量，廊道和踏脚石栖息地的作用就在于恢复个体流动。
Fragmentation changes spatial configuration at a given area: smaller patches push populations below minimum viable size, a higher edge ratio alters light, humidity, and wind while admitting predators and invasive plants, and isolation between patches blocks dispersal and gene flow. Long-running experiments show these effects accumulate, with species numbers continuing to fall for decades in what is called extinction debt. Conservation planning therefore has to weigh area, shape, connectivity, and matrix quality together, which is why corridors and stepping-stone habitats matter for restoring movement.

什么是“再野化”？它和传统生态修复有何不同？
What is rewilding, and how does it differ from traditional ecological restoration?
再野化强调恢复自然过程的自我驱动能力，让生态系统的关键过程重新自行运转。其核心手段之一是重新引入狼、海狸、美洲野牛等关键种，例如顶级捕食者的级联效应会重新调节食草动物与植被的关系，同时允许自然演替占据主导。与传统修复相比，再野化干预更少、空间尺度更大、目标周期更长。其核心挑战是需要足够大的连片栖息地以及公众的接受度。
Rewilding focuses on restoring self-driving natural processes, letting key ecosystem processes run on their own again. Its core tool is reintroducing keystone species such as wolves, beavers, and bison; for example, predator cascades re-regulate herbivores and vegetation, while natural succession is allowed to take the lead. Compared with traditional restoration, rewilding involves less intervention, larger spatial scales, and longer horizons. Its key challenges are the need for large, connected habitats and public acceptance.

DNA条形码如何用于生物多样性监测？
How is DNA barcoding used to monitor biodiversity?
与传统形态鉴定不同，DNA条形码通过比对特定基因片段来鉴定物种，动物通常使用线粒体COI基因。该方法能以参考数据库为对照，识别幼体、组织残片和形态相似的隐存种，弥补形态学的局限。环境DNA（eDNA）则更进一步，直接从水、土壤或空气样本中提取生物遗留的DNA，无需捕捉即可检出物种。eDNA因此特别适合入侵物种的早期预警和稀有物种的野外调查。
Unlike morphology-based identification, DNA barcoding identifies species by matching a standardised gene segment against reference databases; for animals, the mitochondrial COI gene is commonly used. The method recognises larvae, tissue fragments, and morphologically similar cryptic species, overcoming the limits of morphology. Environmental DNA (eDNA) goes a step further, extracting DNA that organisms leave in water, soil, or air so species can be detected without capture. eDNA is therefore especially suited to early warning of invasive species and surveys of rare species.

IPBES (the Intergovernmental Science-Policy Platform on Biodiversity and Ecosystem Services) is an independent intergovernmental body analogous to the IPCC but for biodiversity. Its 2019 Global Assessment concluded that around one million plant and animal species are at risk of extinction and that human activity has profoundly altered most terrestrial and marine ecosystems, calling for transformative change to reverse decline.

矿区复垦从“绿化”升级为“生态重建”，这意味着什么？
What does it mean for mine reclamation to upgrade from greening to ecological reconstruction?
早期复垦常把废弃矿坑填平、种上单一草种，只形成表面绿化。现代复垦则先修复土壤结构，包括覆土、接种菌根真菌、调节酸碱度和重金属含量。在此基础上，再按地形重建水文过程与本土植被的演替序列，并持续监测动物群落是否回归。真正的复垦目标是恢复水源涵养、碳汇和栖息地等可持续的生态系统功能，而非仅仅追求绿色景观。
Early reclamation often flattened abandoned pits and sowed a single grass species, producing little more than surface greening. Modern reclamation first rebuilds soil structure — capping, inoculating mycorrhizal fungi, and adjusting pH and heavy-metal levels. Only then does it reconstruct hydrological processes and native vegetation succession according to terrain, while monitoring whether animal communities return. The true goal is restoring sustainable ecosystem functions such as water retention, carbon storage, and habitat, not just a green surface.

岛屿生物地理学理论（MacArthur 与 Wilson）如何预测栖息地碎片上的物种丰富度？
How does island biogeography theory (MacArthur & Wilson) predict species richness on habitat fragments?
该理论指出，片段越大、离种源越近，物种数越多，达到的平衡由迁入率与灭绝率决定。它预测破碎化森林中较小、孤立的斑块会更快丧失物种，为保护区的设计提供依据。
The theory holds that larger, nearer-to-source fragments hold more species, with richness set by a balance of immigration and extinction rates. It predicts that small, isolated patches in fragmented forests lose species faster, guiding reserve design.

德国保护区飞行昆虫生物量二十七年下降七成多的研究为何影响巨大？
Why was the study showing a 76% drop in flying insect biomass in German reserves so influential?
该研究使用马氏网在多个保护区按统一方法连续采样二十七年，测量的是生物量而非难以标准化的物种计数，因此趋势不易被分类学差异干扰。结果显示夏季飞行昆虫生物量下降约 76%，且发生在受保护的地点，说明压力来自区域尺度的农业强度、农药与生境退化而非保护区内部管理。它把昆虫衰退从零散观察提升为公共议题，也推动了后续对方法学、基线选择与全球代表性的激烈讨论。
The work used Malaise traps with a consistent protocol across multiple reserves for twenty-seven years and measured biomass rather than species counts that are hard to standardise, so the trend is less vulnerable to taxonomic inconsistency. Flying insect biomass in midsummer fell about 76%, and it happened inside protected sites, implying pressures from regional agricultural intensity, pesticides, and habitat degradation rather than reserve management. The paper turned scattered observations of insect decline into a public issue and also triggered vigorous debate about methodology, baseline choice, and global representativeness.

为什么说我们可能正处于“第六次大灭绝”，当前的灭绝速率约为背景值的多少倍？
Why is it said we may be in a 'sixth mass extinction,' and how many times the background rate is current extinction?
化石记录显示地球曾发生五次自然大灭绝；如今由于栖息地破坏、气候变化和过度开发，物种灭绝速率估计为背景（自然）速率的100至1000倍。许多科学家据此认为人类活动正驱动第六次大灭绝，尽管它比以往更慢、但范围同样广泛。
The fossil record shows five past natural mass extinctions; today, driven by habitat loss, climate change, and overexploitation, species are vanishing at an estimated 100 to 1,000 times the background (natural) rate. Many scientists argue human activity is driving a sixth mass extinction—slower than past events but comparably broad in scope.

草原退化后，仅靠“围封禁牧”能否完全恢复？关键措施有哪些？
Can degraded grassland fully recover through fencing and grazing exclusion alone, and what measures are key?
围封禁牧能让植被覆盖和土壤碳储量回升，短期效果明显。但长期完全禁牧会引发枯草堆积、可燃物增多和物种单一化，因为草食动物的适度啃食与踩踏本身就是草原生态过程的一部分。现代草原修复因此主张轮牧、补播乡土草种、科学火烧管理，并恢复大型有蹄类与土壤动物的相互作用。只有把封育与适度利用结合起来，才能重建功能完整的草原。
Fencing and grazing exclusion let vegetation cover and soil carbon recover, with clear short-term gains. But prolonged total exclusion causes litter buildup, fuel accumulation, and species simplification, because moderate grazing and trampling by herbivores are themselves part of grassland ecosystem processes. Modern grassland restoration therefore combines rotational grazing, reseeding native grasses, and scientific fire management, while restoring interactions between large ungulates and soil fauna. Only by combining protection with moderate use can fully functional grasslands be rebuilt.

什么是“第六次大灭绝”？

科学家认为地球正经历由人类活动驱动的第六次物种大灭绝，其灭绝速率远高于自然背景水平。前五次大灭绝由小行星撞击、火山等自然灾变造成，而这一次主要源于栖息地破坏、气候变化和过度开发。阻止它需要在全球范围采取紧急的保护行动。
Scientists argue Earth is undergoing a sixth mass extinction driven by human activity, with extinction rates far above the natural background. The previous five were caused by natural catastrophes like asteroid impacts and volcanoes, while this one stems mainly from habitat destruction, climate change, and overexploitation. Stopping it requires urgent global conservation action.

岛屿生物地理学理论如何影响了自然保护区的设计？
How did island biogeography theory reshape the design of nature reserves?
麦克阿瑟与威尔逊 1967 年提出，岛屿物种数由迁入率与灭绝率的动态平衡决定，面积越大灭绝率越低，距大陆越近迁入率越高，可用物种-面积关系刻画。保护生物学家把破碎化生境视为陆地上的岛屿，据此主张保护区宜大、宜近、宜有廊道相连，并尽量减少边缘效应。这一推论也引发了著名的单个大保护区还是若干小保护区之争，后续研究表明答案取决于目标物种的扩散能力与干扰格局。
MacArthur and Wilson argued in 1967 that species number on an island reflects a dynamic equilibrium between immigration and extinction, with larger area lowering extinction and proximity to a mainland raising immigration, summarised by species-area relationships. Conservation biologists treated fragmented habitats as terrestrial islands and inferred that reserves should be large, close together, connected by corridors, and shaped to minimise edge effects. The framework also sparked the single-large-or-several-small debate, and later work showed the answer depends on target species' dispersal ability and disturbance regimes.

亚马逊雨林的临界点假说说的是什么？为什么与降水自循环有关？
What does the Amazon tipping point hypothesis claim, and why does it hinge on rainfall recycling?
亚马逊约有三到五成的降水来自森林自身的蒸腾，水汽随信风向内陆逐级再循环，形成所谓飞行的河流。若森林砍伐与火灾把树冠覆盖削减到某个阈值，蒸腾输入不足会缩短旱季降水、加剧火险，使东南部逐步转为稀树草原，这一自我强化过程就是临界点假说。Lovejoy 与 Nobre 提出在叠加升温背景下，20% 至 25% 的森林损失就可能触发转变，而航空观测已发现亚马逊东南部在部分年份转为净碳源。
Between a third and a half of Amazon rainfall is generated by the forest's own transpiration, with moisture recycled inland stage by stage in what are called flying rivers. If deforestation and fire cut canopy cover past a threshold, reduced transpiration shortens the wet season and raises fire risk, converting the south-east progressively toward savanna — a self-reinforcing process that is the tipping point hypothesis. Lovejoy and Nobre argued that with added warming a loss of 20–25% of the forest could trigger the shift, and aircraft measurements have already found the south-eastern Amazon acting as a net carbon source in some years.

新烟碱类农药为何被欧盟限制户外使用？它对传粉昆虫的影响机制是什么？
Why did the European Union restrict outdoor use of neonicotinoids, and how do they affect pollinators?
新烟碱类是选择性作用于昆虫烟碱型乙酰胆碱受体的神经毒剂，作为种子包衣被植物吸收后进入木质部并出现在花粉与花蜜中，使传粉者长期低剂量暴露。田间尺度研究发现，暴露会损害蜜蜂的导航与学习能力、降低蜂王产卵与野生蜂群建群成功率，属于亚致死但影响种群续存的效应。欧洲食品安全局的评估支持了风险结论，欧盟自 2018 年起禁止吡虫啉、噻虫嗪和噻虫胺的户外使用。
Neonicotinoids are neurotoxins that act selectively on insect nicotinic acetylcholine receptors; applied as seed coatings, they move systemically through the xylem and appear in pollen and nectar, giving pollinators prolonged low-dose exposure. Field-scale studies found impaired navigation and learning in honeybees and reduced queen production and colony establishment in wild bees — sublethal effects that nonetheless undermine population persistence. After European Food Safety Authority assessments supported those risk conclusions, the EU banned outdoor use of imidacloprid, thiamethoxam, and clothianidin from 2018.

生态修复中的“参照生态系统”起什么作用？为什么不能简单照抄？
What role does a reference ecosystem play in restoration, and why can't it simply be copied?
参照生态系统指目标地区历史上存在或残存至今的健康生态系统，它为修复提供物种组成、结构和功能的基准，相当于给修复设置一个靶心。参照系统的价值在于让修复有据可依，避免随意拼凑植物。但气候与土地利用已经发生变化，原样照搬历史状态既不现实，也难以适应未来条件。因此现代修复把参照当作基线，再结合目标物种与未来气候设计多目标方案，即参照加目标导向的修复。
A reference ecosystem is a historical or remnant healthy system in the target region that provides baselines for species composition, structure, and function — the bullseye for restoration. Its value is giving restoration a benchmark, avoiding arbitrary plant mixes. But climate and land use have changed, so copying the historical state is unrealistic and poorly suited to future conditions. Modern practice therefore uses references as baselines while designing multi-objective schemes around target species and future climate — reference plus target-driven restoration.

外来入侵物种的根除成功率在岛屿上远高于大陆,繁殖压力与再传入通道是如何解释这道鸿沟的?
Eradication of alien invasive species succeeds far more often on islands than on continents: how do propagule pressure and reinvasion pathways explain that gap?
岛屿边界明确、面积有限,毒饵投放、隔离围栏与口岸检疫可以一次性切断残存个体及其外部补给,新西兰离岛鼠类清除项目已反复验证该模式。大陆拥有连续的陆生扩散走廊和海量未查验的货运通道,一旦每次引入个体数越过种群建立阈值,根除之后数年内定殖便会重演。防控重心因此整体前移到边境拦截以及早期发现加快速响应。
Islands present bounded, finite terrain where toxic baiting, exclusion fencing, and port inspection can sever both surviving individuals and outside replenishment in a single operation, as repeated rodent eradications on New Zealand offshore islands demonstrate. Continents carry continuous terrestrial corridors plus enormous volumes of uninspected freight, and whenever introduction events exceed the establishment threshold, colonization recurs within just a few years of any successful eradication. Management emphasis has consequently shifted upstream toward border interception paired with early detection and rapid response.

功能多样性（functional diversity）比物种数量更能预测生态系统功能吗？
Does functional diversity predict ecosystem function better than species count?
是的。物种丰富度只计'有多少种'，而功能多样性衡量性状覆盖（如根系深度、固氮能力）是否足以支撑生产力、养分循环等过程。实验显示功能冗余低时，失去个别物种即可导致功能骤降。
Yes. Species richness only counts 'how many,' while functional diversity measures whether trait coverage (root depth, N-fixation, etc.) sustains productivity and nutrient cycling. Experiments show that with low redundancy, losing a single species can collapse a function.

地球生命力指数下降七成多，是否意味着野生动物数量减少了七成？
Does a 73% decline in the Living Planet Index mean wildlife numbers have fallen by 73%?
并不是。地球生命力指数追踪数千个脊椎动物种群的相对变化，报告的是所监测种群规模变化率的几何平均值，而不是个体总数的加和。因此少数急剧崩溃的种群会显著拉低平均值，而指数上升的种群不会等量抵消。世界自然基金会 2024 年报告给出 1970 至 2020 年间约 73% 的平均降幅，正确读法是被监测种群的平均衰减幅度很大，淡水与热带地区最严重。
No. The Living Planet Index tracks relative change in thousands of vertebrate populations and reports the geometric mean of those rates of change, not a sum of individual animals. A few collapsing populations therefore pull the average down sharply, while recovering populations do not offset them proportionally. WWF's 2024 report gives an average decline of about 73% from 1970 to 2020, which should be read as a large average shrinkage among monitored populations, worst in freshwater systems and the tropics.

什么是“生态位”？相近的物种为什么能在同一片森林里共存？
What is a niche, and why can similar species coexist in the same forest?
生态位是一个物种在生态系统中做什么的完整画像，包括它吃什么、何时活动、住在哪一层、与谁竞争或互利。相近物种通过“生态位分化”错开利用资源，比如不同鸟在树冠的不同高度觅食，就能避免直接竞争、和平共存。理解生态位，是保护和管理生物多样性的基础。
A niche is the full job description of a species in an ecosystem — what it eats, when it is active, which layer it inhabits, and whom it competes with or helps. Similar species coexist through niche differentiation: birds that feed at different heights of the same tree, for example, avoid direct competition. Understanding niches underpins biodiversity conservation and management.

什么是伞护种？
What is an umbrella species?
伞护种是需要大面积栖息地的大型物种，保护它就能顺带庇护同区域内的许多其他物种，如东北虎和灰熊。它不像关键种那样靠生态功能，而靠空间需求发挥保护作用。选定伞护种可简化保护区的规划。
An umbrella species needs large habitat and protecting it shelters many co-occurring species, such as the Amur tiger or grizzly bear. Unlike keystones, it protects via spatial needs rather than ecological function. Choosing one simplifies reserve planning.

传粉昆虫数量下降对粮食安全有何影响？
How does the decline of pollinating insects affect food security?
约七成农作物依赖动物传粉，蜜蜂、蝴蝶等数量下降会直接降低果实和种子产量。这威胁坚果、水果和部分油料作物的供给并推高价格。保护野花带和减少杀虫剂是缓解途径。
Roughly 70 percent of crops rely on animal pollination, so declines in bees and butterflies directly cut fruit and seed yields. This threatens supplies of nuts, fruits and some oil crops and raises prices. Protecting wildflower strips and cutting pesticides help.

基因多样性对物种适应气候变化为何重要？
Why does genetic diversity matter for climate adaptation?
种群内基因多样性越高，面对变暖、病害等新压力时出现适应个体的概率越大，避免近交衰退并维持进化潜力；单一栽培作物正是因基因狭窄而易遭疫病横扫。
Higher within-population genetic diversity raises the odds that some individuals withstand warming or disease, avoiding inbreeding depression and preserving evolutionary potential; uniform crops fail exactly because their narrow genetics let epidemics sweep through.

关键种是对生态系统结构和稳定影响远大于其数量比例的物种，移除后群落会剧烈变化。典型例子是海獭，它捕食海胆从而保护海带森林；还有非洲象通过取食塑造稀树草原。保护关键种能撬动整个生态网络的存续。
A keystone species has an impact on ecosystem structure and stability far greater than its abundance; removing it triggers dramatic community change. A classic example is the sea otter, which eats sea urchins and protects kelp forests, and the African elephant, which shapes savanna through feeding. Protecting keystones sustains the whole ecological network.

关键种与伞护种在保护规划中的作用有何不同？
How do keystone and umbrella species differ in their roles in conservation planning?
关键种对生态系统有不成比例的巨大影响，移除它会引起连锁崩溃，例如海獭消失导致海藻林被海胆啃光；伞护种则需要大面积完整栖息地，保护它便顺带保护了同区域的其他物种。规划中，关键种用于维持生态过程，伞护种用于划定保护区的范围。
A keystone species exerts a disproportionately large influence — removing it triggers cascading collapse, as when sea otters vanish and urchins devour kelp forests. An umbrella species needs large intact habitat, so protecting it incidentally protects co-occurring species. In planning, keystone species guide maintaining ecological processes, while umbrella species guide reserve sizing.

物种丰富度相同的两个群落，为什么多样性指数可能不同？
If two communities have the same species richness, why can their diversity indices still differ?
丰富度只统计物种数目，而香农指数还考虑各物种个体数的均匀度：一个“1种占90%”的群落，信息量和稳定性都低于“10种各占10%”的群落。香农指数 H'=-Σpi·ln(pi)，个体分布越均匀数值越大，因此它是比单纯物种数更完整的多样性度量。
Richness only counts species; the Shannon index also accounts for the evenness of individuals: a community with one species holding 90% of individuals carries less information and stability than one with ten species at 10% each. Shannon H'=-Σ pi·ln(pi) grows as individuals are more evenly spread, making it a fuller measure of diversity than a plain species count.

什么是物种的“特有性”？
What is species endemism?
特有性指某个物种仅天然分布于很狭窄的地理范围，如某座岛屿或某段山脉。特有物种往往对栖息地变化极为敏感，一旦当地生境被破坏就极易灭绝。
Endemism means a species occurs naturally only in a very limited area, such as a single island or mountain range. Endemics are highly sensitive to habitat change and can go extinct quickly if their local habitat is destroyed.

珊瑚礁修复中的“珊瑚移植”有什么局限？
What are the limitations of coral transplantation in reef restoration?
珊瑚移植只是修复的一种工具：被漂白或退化的珊瑚礁，如果水温升高、酸化与污染没有改善，移植的珊瑚仍难以长期存活。近年更强调先培育耐热珊瑚苗圃，再配合海洋保护区的整体管理。修复不是万灵药，预防退化和减少压力源才是根本。
Coral transplantation is only one restoration tool: on bleached or degraded reefs, transplanted corals struggle to survive long-term if warming, acidification, and pollution persist. Recent efforts emphasise heat-tolerant coral nurseries combined with integrated management of marine protected areas. Restoration is not a silver bullet — preventing degradation and reducing stressors is fundamental.

为什么食物链越往上，能量越少？这跟人类吃什么有关吗？
Why does energy shrink up the food chain, and does it matter what humans eat?
能量在食物链每一级传递时，大约只有10%转化为新的生物量，其余都在呼吸和代谢中散失，所以能量金字塔逐级收窄，顶级捕食者数量最少。这也意味着吃肉比吃素占用更多土地和水，因为粮食要先喂动物。理解这个比例，是选择低碳饮食的科学起点。
Only about 10 percent of energy is converted into new biomass at each step of the food chain; the rest is lost to respiration and metabolism, so the energy pyramid narrows upward and top predators are fewest. This is also why meat demands far more land and water than plants — crops must feed animals first. Understanding that ratio is the scientific starting point for a lower-footprint diet.

生物之间除了吃与被吃，还有哪些重要的关系？
Besides eating and being eaten, what other important relationships exist between species?
种间关系主要有捕食、竞争、寄生和共生。共生包括互利共生，比如豆科植物与根瘤菌合作固氮、小丑鱼与海葵互保；也包括一方受益、另一方不受影响的共栖。这些关系共同调节种群数量、驱动演化，是生态系统的“隐形骨架”。
Species interact through predation, competition, parasitism and symbiosis. Symbiosis includes mutualism — legume plants and nitrogen-fixing bacteria, or clownfish sheltered by anemones — and commensalism, where one partner benefits and the other is unaffected. Together these relationships regulate populations and drive evolution, forming the hidden skeleton of every ecosystem.

为什么“遗传多样性”是生物多样性中被低估的一层？
Why is genetic diversity an underappreciated layer of biodiversity?
遗传多样性是物种内部的基因差异，决定了物种适应环境变化的潜力：基因库越丰富，越可能涌现抗病、耐旱的个体。在农业上，现代单一高产品种使许多传统作物品种消失，风险高度集中；挪威斯瓦尔巴全球种子库正是为保存这一层多样性而建立的。
Genetic diversity is the variation within a species and sets its adaptive potential: richer gene pools make disease-resistant or drought-tolerant individuals more likely to emerge. In agriculture, modern uniform high-yield varieties have displaced many traditional cultivars, concentrating risk; the Svalbard Global Seed Vault exists precisely to preserve this layer.

为什么“自然恢复”有时优于大规模植树？
Why is natural regeneration sometimes better than large-scale tree planting?
自然恢复利用土壤中残留的种子库和邻近森林的天然扩散，成本低、遗传多样性强，形成的林分结构更复杂，能支撑更完整的食物网。而大规模单一树种人工林在干旱地区可能因缺水而死亡，生态功能也有限。科学实践常把被动恢复与辅助措施结合，而非一刀切地植树。
Natural regeneration relies on the dormant seed bank in soil and seed dispersal from nearby forests — it is cheap, genetically diverse, and produces structurally complex forests that support fuller food webs. Large monoculture plantations can die from water stress in dry regions and provide limited ecological function. Good practice blends passive regeneration with assisted measures rather than one-size-fits-all planting.

入侵物种造成的经济损失为何常被低估？
Why are the economic costs of invasive species usually underestimated?
多数统计只记录看得见的直接支出，例如清除斑马贻贝堵塞的取水管道、修复电站冷却系统或扑灭疫情，而生态系统服务退化、渔业与农业长期减产、以及本地物种灭绝造成的不可逆损失很难货币化。数据缺口也偏向富裕国家和已引起关注的物种，热带地区与土壤生物群的成本几乎空白。基于全球数据库的综合研究估算 1970 至 2017 年累计成本已超过一万亿美元，且报告值随年份快速上升。
Most tallies capture only visible direct spending — clearing zebra mussels from intake pipes, repairing power-plant cooling systems, or eradicating outbreaks — while degraded ecosystem services, sustained losses in fisheries and agriculture, and irreversible native extinctions resist monetisation. Reporting gaps also skew toward wealthy countries and charismatic or notorious species, leaving tropical regions and soil biota nearly unquantified. A synthesis built on a global cost database put cumulative costs from 1970 to 2017 above one trillion US dollars, with reported figures rising steeply over time.

1995 年狼群回归后，研究者观察到马鹿数量下降并改变觅食行为，河谷柳树和白杨恢复，河岸稳定、河狸与鸣禽增多，被称为营养级级联乃至景观尺度的营养级级联。争论在于这些变化难以与同期的干旱波动、灰熊与美洲狮压力、麋鹿管理政策和河流地貌自然演替区分开来，长期样地数据显示柳树恢复在不同河段差异很大。这个案例提醒人们，自然实验缺少对照，因果归属需要谨慎的统计设计。
After wolves returned in 1995, researchers recorded declining elk numbers and altered browsing, recovering willow and aspen in valley bottoms, more stable banks, and increases in beaver and songbirds — described as a trophic cascade of landscape scale. The dispute is that these shifts are hard to separate from concurrent drought variability, predation by bears and cougars, elk harvest policy, and natural channel evolution, and long-term plots show willow recovery varying strongly between reaches. The case is a reminder that natural experiments lack controls, so causal attribution demands careful statistical design.

生物多样性为何有助于生态系统的气候韧性？
Why does biodiversity help ecosystems resist climate change?
物种多样的生态系统通常功能更冗余、恢复力更强，更能承受干旱、高温等扰动。不同物种对环境变化的响应各异，可避免系统整体崩溃。保护生物多样性因此也是增强气候适应能力的策略。
Species-rich ecosystems tend to have redundant functions and greater resilience, better withstanding disturbances like drought and heat. Different species respond differently to change, preventing whole-system collapse. Protecting biodiversity is thus also a climate-adaptation strategy.

就地保护与迁地保护有何区别？为什么迁地保护不能替代就地保护？
What is the difference between in-situ and ex-situ conservation, and why can't ex-situ replace in-situ?
就地保护在物种原生境中保护种群和生态过程（保护区、国家公园），是最根本的方式；迁地保护（动物园、植物园、种子库）在野外濒临灭绝时兜底，例如华南虎和苏铁。迁地种群小、遗传多样性低、缺少自然选择压力，最终目标是放归并恢复野生种群，所以它只能补充而不能替代就地保护。
In-situ conservation protects populations and ecological processes in their native habitats through reserves and national parks and is fundamental. Ex-situ conservation — zoos, botanic gardens, and seed banks — is a safety net when species near extinction in the wild, e.g., the South China tiger and cycads. Ex-situ populations are small, genetically poorer, and lose natural selection pressure; the ultimate goal is reintroduction to restore wild populations, so it complements but never replaces in-situ protection.

什么是特有物种？
What is an endemic species?
特有物种是指只在世界某一特定地区自然分布、别处找不到的物种，如澳大利亚的考拉、中国的大熊猫。由于分布范围狭小，它们对环境变化和栖息地破坏格外脆弱。保护特有物种往往也是保护当地独特生态的标志。
An endemic species occurs naturally only in one specific region and nowhere else, such as the koala in Australia or the giant panda in China. Because their ranges are narrow, they are especially vulnerable to environmental change and habitat loss. Protecting endemics also protects a region's unique ecology.

入侵物种为什么能让本地生态系统“伤筋动骨”？
Why can invasive species wreak havoc on native ecosystems?
入侵物种被有意或无意带入缺乏天敌的新环境后，可能快速繁殖、抢占食物和空间、改变生境结构，甚至直接导致本地物种减少或灭绝，还带来农业和健康损害。水葫芦、红火蚁等都是著名案例。防控的最佳时机是入侵早期，靠检疫和快速清除；一旦站稳脚跟，清除代价将成倍上升。
Invasive species, carried deliberately or by accident into places with no natural enemies, can breed explosively, monopolise food and space, restructure habitats and drive local species down or out — while damaging farming and health. Water hyacinth and red imported fire ants are famous examples. The best window for control is early invasion, through quarantine and rapid removal; once established, eradication becomes vastly costlier.

为什么岛屿上的物种更容易灭绝？
Why are island species more vulnerable to extinction?
岛屿面积小、种群数量有限，且许多物种在隔离环境中进化、缺乏天敌防御，外来物种或环境变化很容易把它们推到灭绝边缘。
Islands have small areas and limited populations, and many species evolved in isolation without defenses against predators, so introduced species or change can quickly drive them extinct.

什么是“生态系统服务”，它通常被分为哪几类？
What are ecosystem services, and how are they typically classified?
生态系统服务是自然生态系统为人类提供的惠益，千年生态系统评估将其分为供给服务（食物、水、木材）、调节服务（气候、洪水、授粉）、文化服务（休闲、精神）和支持服务（土壤形成、养分循环）。它强调保护自然不仅是伦理需要，也具有实际经济与生存价值。
Ecosystem services are the benefits nature provides to people; the Millennium Ecosystem Assessment groups them into provisioning (food, water, timber), regulating (climate, floods, pollination), cultural (recreation, spiritual), and supporting services (soil formation, nutrient cycling). It frames nature protection as not only ethical but also of practical economic and survival value.

What is genetic diversity?
遗传多样性指同一物种内部不同个体之间基因的差异，是物种适应环境变化和抵御疾病的根本。遗传单一的作物品种一旦遭遇新病害就可能大面积绝收。保护遗传多样性对农业和野生种群的长期生存都至关重要。
Genetic diversity is the variation in genes among individuals of the same species, the basis for adapting to change and resisting disease. A genetically uniform crop can be wiped out by a new disease. Preserving genetic diversity is vital for both agriculture and the long-term survival of wild populations.

珊瑚白化在细胞层面发生了什么？为什么白化不等于立即死亡？
What happens at the cellular level during coral bleaching, and why is bleaching not immediate death?
珊瑚组织内共生着虫黄藻，为宿主提供大部分光合产物并赋予颜色。水温异常升高时，藻类光系统受损产生活性氧，珊瑚为避免氧化损伤将共生藻排出体外，组织随之透出碳酸钙骨骼的白色，这就是白化。此时珊瑚仍然活着，若热应力在数周内缓解，可以重新获取共生藻并恢复，但长时间高温会导致饥饿死亡与藻类覆盖。美国国家海洋和大气管理局的珊瑚礁观察项目在 2024 年确认了有记录以来的第四次全球白化事件。
Coral tissue hosts symbiotic zooxanthellae that supply most of the host's photosynthetic energy and give the colony its colour. When water warms abnormally, the algal photosystem is damaged and generates reactive oxygen species, so the coral expels its symbionts to limit oxidative injury and the white calcium carbonate skeleton shows through — that is bleaching. The animal is still alive, and if heat stress eases within weeks it can reacquire symbionts and recover, but prolonged heat leads to starvation, mortality, and algal overgrowth. NOAA's Coral Reef Watch confirmed the fourth global bleaching event on record in 2024.

什么是“生态系统服务”？为什么经济学家也在研究它？
What are ecosystem services, and why are economists studying them?
生态系统服务是自然系统为人类提供的各种惠益：供给服务如粮食和淡水，调节服务如气候、洪水与传粉，支持服务如养分循环，文化服务如美景与游憩。把森林、湿地、珊瑚礁的服务折算成经济价值，可以让保护决策进入算账体系，例如一片湿地净化污水的价值，往往高于把它填平开发。
Ecosystem services are the benefits nature provides: provisioning (food, freshwater), regulating (climate, flood control, pollination), supporting (nutrient cycling) and cultural (scenery, recreation). Putting a monetary value on the services of forests, wetlands and reefs brings conservation into cost–benefit decisions — a wetland's water-purifying value often outweighs the profit from draining and developing it.

Roads cut continuous habitat into isolated patches, so small populations struggle to move and exchange genes, raising inbreeding and local extinction risk. Ecological corridors — green bridges, culverts, and riparian strips — reconnect the fragments so wildlife can cross safely and gene flow resumes, and also help species track shifting climates.

城市绿地、屋顶花园、社区菜园以及传粉者友好的种植（蜜源植物、减少农药）能为蜜蜂、蝴蝶和鸟类提供碎片化但可用的栖息地，一些城市物种甚至比乡村适应得更好。通过本土植物种植和生态化养护等社区行动，居民与自然重新连接，城市也能成为物种扩散的“跳板”。
Urban green spaces, rooftop gardens, community gardens, and pollinator-friendly planting (nectar plants, less pesticide) provide fragmented but usable habitat for bees, butterflies, and birds — some species even thrive better in cities. Through community actions like native planting and ecological gardening, residents reconnect with nature, and cities become stepping stones for species dispersal.

湿地生态修复时，为什么优先种植本土水生植物而不是外来观赏植物？
Why are native aquatic plants preferred over introduced ornamental species when restoring wetlands?
本土水生植物长期适应当地水文与气候，能固定底泥、净化水质，并为鸟类和鱼类提供食物与繁殖生境；外来观赏植物则可能疯长扩散、挤压本地物种。修复的目标是重建能自我维持的湿地生态系统，而非单纯追求景观效果，因此本土植物成活率高、生态收益更大。
Native aquatic plants are adapted to local hydrology and climate; they stabilise sediment, purify water, and provide food and breeding habitat for birds and fish. Introduced ornamentals can spread aggressively and displace natives. Because restoration aims to rebuild self-sustaining wetland ecosystems rather than scenery, native species give higher survival and greater ecological returns.

The Red List ranks extinction risk from lowest to highest: Least Concern, Near Threatened, Vulnerable, Endangered, Critically Endangered, Extinct in the Wild, and Extinct. Assessments use population size and trend, geographic range, and threats. Critically Endangered is riskier than Endangered, which is riskier than Vulnerable; higher categories receive higher conservation priority.

About three-quarters of crop species depend on animal pollination — apples, strawberries, coffee and nuts all rely on bees, butterflies and other pollinators. These insects face habitat loss, pesticide exposure, disease and climate change all at once. Protecting them can start with wildflower strips, avoiding sprays during bloom, and ecological corridors — safeguarding both nature and harvests.

互花米草为何能在中国东部沿海滩涂迅速扩张并压制芦苇等本土挺水植物?
Why has Spartina alterniflora been able to spread so rapidly across eastern China's coastal mudflats and outcompete native emergent plants such as Phragmites australis?
互花米草兼具耐盐、耐淹能力并拥有泌盐组织,可在从光滩到高潮缘的宽潮位带上定居,这是本土芦苇难以企及的低潮带生态位。其根状茎克隆生长能快速锁定新淤裸滩,大量种子又借涨落潮流远距离播种。繁殖与生理优势叠加,使其在苏闽等地形成排他性的单优群落。
The cordgrass combines salinity and submergence tolerance with salt-excreting glands, letting it settle across a tidal range from open mudflat to high-marsh margins, a niche the native reed cannot occupy on lower flats. Rhizomatous clonal growth quickly locks onto newly formed bare flats, while abundant seeds are broadcast long distances by tidal currents. These physiological and reproductive advantages stack up into exclusive monodominant stands along the Jiangsu and Fujian coasts.

什么是指示物种？科学家为何监测它们？
What is an indicator species and why do scientists monitor them?
指示物种对环境变化（如污染或温度）特别敏感，其数量变化能提前反映生态系统健康。例如河蚌与两栖类常被用作水质与湿地退化的哨兵。
Indicator species are especially sensitive to environmental change such as pollution or temperature, so their population shifts flag ecosystem health early. Mussels and amphibians, for example, act as sentinels for water quality and wetland decline.

栖息地破碎化如何影响物种生存？
How does habitat fragmentation affect species survival?
道路、农田和城市把连片栖息地切成小块，使种群被隔离、基因交流减少。小块栖息地更易受边缘效应和外来干扰，局部灭绝风险上升。修建生态廊道可帮助动物重新连通。
Roads, farmland and cities split continuous habitat into patches, isolating populations and reducing gene flow. Small patches suffer stronger edge effects and disturbances, raising local extinction risk. Ecological corridors help animals reconnect.

IUCN 红色名录中「濒危」与「极危」有什么区别？
What is the difference between Endangered and Critically Endangered on the IUCN Red List?
两者都属于受威胁级别，但「极危」（CR）比「濒危」（EN）面临更高的近期灭绝风险，其种群下降或分布收缩幅度更大。IUCN 用定量标准（如三代内下降 ≥80%）来划分等级。
Both are threatened categories, but Critically Endangered (CR) faces a far higher near-term extinction risk than Endangered (EN), with steeper population or range decline. IUCN uses quantitative criteria such as ≥80% decline over three generations.

生物多样性包含哪三个层次？
What are the three levels of biodiversity?
生物多样性通常分为三个层次：遗传多样性（同一物种内部的基因差异）、物种多样性（物种的数量和丰富度）和生态系统多样性（不同生态系统类型的多样程度）。这三个层次相互支撑，缺一不可。保护生物多样性需要在三个层面同时努力。
Biodiversity is usually divided into three levels: genetic diversity (gene variation within a species), species diversity (number and abundance of species), and ecosystem diversity (variety of ecosystem types). These levels support one another and none can be neglected. Conservation must work at all three.

珊瑚白化是由什么原因引起的？
What causes coral bleaching?
珊瑚与虫黄藻共生，后者为珊瑚提供颜色和养分。当海水异常升温或遭受其他环境胁迫时，珊瑚会排出虫黄藻而变白，失去主要能量来源。若高温持续，珊瑚将饥饿死亡，礁生态系统随之崩溃。
Corals live with zooxanthellae that give them colour and nutrients. When seas warm abnormally or face other environmental stressors, corals expel these algae and turn white, losing their main energy source. If heat persists, corals starve and the reef ecosystem collapses.

入侵物种是如何造成生态损失的？
How do invasive species cause ecological damage?
入侵物种在新环境中缺少天敌制约，会快速繁殖并抢占本地物种的食物和空间。它们可能改变土壤、水文甚至引发火灾模式，导致本地物种衰退。防治关键在于源头把关和早期快速清除。
Invasive species lack natural predators in new environments, so they multiply fast and seize the food and space of natives. They can alter soils, hydrology and even fire regimes, driving native decline. Prevention at the source and early rapid removal are key.

“多样性-稳定性”假说认为生物多样性高的生态系统更稳定吗？
Does the diversity–stability hypothesis say more diverse ecosystems are more stable?
一般认为物种越多，功能冗余与互补越强，面对干旱、病害等扰动时总体生产力与功能更不易崩溃；但也有研究指出多样性提升“稳定性”而非所有维度的“不变”。
More species usually mean more functional redundancy and complementarity, so productivity and function resist drought or disease better; some note diversity boosts 'stability' but not invariance in every dimension.

外来入侵物种为什么常常造成大问题？
Why do invasive alien species often cause big problems?
外来入侵物种被带到新地方后，往往没有天敌制约，会迅速繁殖并挤占本地物种的生存空间和食物。它们每年给农业、渔业和生态系统带来巨大损失，是全球生物多样性下降的主要原因之一。
Invasive alien species moved to new places often lack natural enemies, so they spread fast and crowd out native species for space and food. They cost agriculture, fisheries and ecosystems dearly each year and are a leading driver of biodiversity loss.

蜜蜂消失的话,我们的餐桌会发生什么?
What happens to our dinner table if bees disappear?
很多水果蔬菜都要靠蜜蜂传粉:苹果、草莓、西瓜、黄瓜都会大减产,餐桌上只剩米饭和土豆,冰淇淋也没了香草口味(香草也要虫媒授粉)。爱因斯坦那句没说过的名言虽然夸张,但蜜蜂确实扛着全球三分之一的食物生产。
Bees pollinate much of our produce: apples, strawberries, watermelon and cucumbers would shrink badly, leaving mostly rice and potatoes — even vanilla ice cream suffers since vanilla needs insect pollination too. The famous Einstein warning? He never said it — but bees truly carry about a third of world food production.

什么是物种丰富度？
What is species richness?
物种丰富度是指一个地区内物种数目的多少，是衡量生物多样性的最直接指标之一。它只考虑“有多少种”，并不区分每种数量的多少。热带地区的物种丰富度通常远高于寒带和极地。
Species richness is the number of species in a given area, one of the most direct measures of biodiversity. It counts only how many kinds and does not weigh their abundance. Tropical regions typically have far higher species richness than cold or polar areas.
