海草床恢复为何失败率高，关键限制是什么？
Why do seagrass restorations often fail, and what limits them?
海草对水质浊度、温度、摄食和底质敏感；种苗移栽常因水文扰动、光照不足或草食动物啃食而低成活。需先改善水质与栖息条件再种植。
Seagrass is sensitive to turbidity, temperature, grazing and substrate; transplants often die from hydrodynamic disturbance, low light or herbivores. Improve water quality and habitat first, then plant.

珊瑚礁修复中常用的幼体移植与珊瑚苗圃技术原理是什么？
What are the principles of larval propagation and coral nurseries used in reef restoration?
收集珊瑚受精卵在可控环境中培育幼体，再固着到退化礁体；或先在苗圃中培养断枝再移植。配合耐热株系筛选，可提升修复礁对热胁迫的抵抗力。
Spawned gametes are reared in controlled settings and settled onto degraded reef, or fragments are grown in nurseries then transplanted. Selecting heat-tolerant genotypes improves restored reefs' resistance to thermal stress.

为何有些海洋保护区形同虚设，而有些能显著恢复渔业？其有效性由哪些因素决定？
Why are some marine protected areas ineffective while others markedly recover fisheries, and what determines effectiveness?
仅名义设立却缺乏执法的「纸面保护区」几乎无生态收益；真正有效的 MPA 需充分禁捕、面积足够大并保持栖息地连通性。个体向周边洄游产生的溢出效应才是惠益渔业的关键。
Nominal 'paper parks' with no enforcement yield little ecological gain; effective MPAs need full no-take status, adequate size, and habitat connectivity. Spillover from individuals migrating outward is what benefits fisheries.

珊瑚白化是怎么发生的？
How does coral bleaching occur?
当海水温度过高或光照过强时，珊瑚会排出共生的虫黄藻，露出白色骨骼。若压力持续，珊瑚将饥饿死亡；若环境恢复，部分珊瑚可重新获得虫黄藻。
Under high temperature or excess light, corals expel their symbiotic zooxanthellae and reveal white skeletons. Prolonged stress starves the coral, but if conditions recover some corals can regain symbionts.

人工鱼礁提升生物多样性的机理是什么？其生态风险有哪些？
What mechanisms let artificial reefs boost biodiversity and what ecological risks do they carry?
人工鱼礁通过提供硬质附着基与三维结构增加栖息地复杂度和庇护所。但若布局不当可能吸引过度捕捞或改变物种组成，需科学选址与监测。
Artificial reefs add habitat complexity and shelter by providing hard substrate and three-dimensional structure. Poor siting can attract overfishing or shift species composition, so scientific placement and monitoring are required.

海带森林恢复对近岸生态有何意义？
Why does kelp forest restoration matter for nearshore ecology?
海带森林是温带近岸的基石生境，为鱼类和无脊椎动物提供食物与庇护并吸收碳。海胆暴发和海水变暖导致其退化，需通过捕食者恢复等手段修复。
Kelp forests are temperate nearshore foundation habitats feeding and sheltering fish and invertebrates while absorbing carbon. Urchin outbreaks and warming drive decline, so restoration often rebuilds predator control.

海草床为什么被称为“海洋之肺”以外的“蓝碳宝库”？
Why is seagrass meadow called a 'blue-carbon treasury' beyond 'ocean's lungs'?
海草覆盖不到0.2%海床，却储存了约10%的海洋沉积物碳，且根状茎固沙护岸、为鱼类育幼。退化后碳库易释放。
Seagrass covers <0.2% of seafloor yet stores ~10% of ocean sediment carbon; its rhizomes stabilize sediment and shelter fish nurseries. Degradation releases that stock.

蓝碳生态系统的碳汇核算面临哪些方法学挑战？
What methodological challenges face carbon accounting for blue carbon ecosystems?
蓝碳核算需区分总固碳与净固碳，并考虑甲烷释放、沉积速率和可逆性。红树林与海草的碳大多存于土壤，扰动后易重新释放，因此持久性是核算核心。
Blue carbon accounting must separate gross from net sequestration and account for methane release, sedimentation, and reversibility. Most carbon sits in soils that re-emit when disturbed, making permanence central to accounting.

珊瑚与虫黄藻之间的共生关系是怎样运作的？
How does the symbiosis between corals and zooxanthellae work?
虫黄藻在珊瑚组织内进行光合作用，为宿主提供糖分等有机物；珊瑚则提供保护、营养盐和光照环境。这种互利是造礁珊瑚生长的基础。
Zooxanthellae photosynthesize within coral tissue, supplying the host with sugars and other organics, while the coral offers protection, nutrients, and light. This mutualism underpins reef-building coral growth.
