物种丰富度的纬度下降是生物多样性的一种普遍空间模式，也适用于海洋物种。根据海洋物种丰富度的纬度梯度，预计低纬度地区的海洋生态系统服务潜力将因生物多样性的增加而增加。然而，海洋生态系统服务与纬度和生物多样性的关系知之甚少。我们估计了黑潮洋流区域（8°37 'N-33°24' N）从热带到温带的十个珊瑚栖息地的三种主要珊瑚礁鱼类生态系统服务（渔业生产、观赏鱼生产和休闲潜水）的纬度模式及其与潜在种群生物多样性的关系。使用实地调查数据和相关网站和管理统计数据的信息。我们发现，该地区的观赏鱼生产和潜水的潜在种群从南到北呈纬度下降趋势，而渔业生产的高峰出现在热带和亚热带地区。我们的研究结果还表明，生物多样性对三种生态系统服务的潜在种群产生了强有力的积极影响，突出了保护不同鱼类物种以维持高水平的多种服务的重要性。珊瑚礁鱼类为基础的生态系统服务的广泛空间格局是有用的基线，为未来的变化评估。由于气候变化对珊瑚礁鱼类的影响预计在不同的纬度带之间会有所不同，因此我们对生态系统服务的估计推断了各个区域应对气候变化的具体管理和经济行动。
The latitudinal decline of species richness is a general spatial pattern of biodiversity, and it applies to marine species as well. Based on a latitudinal gradient of marine species richness, potential stocks of marine ecosystem services are expected to be higher in lower latitudes through increment in biodiversity. However, little is known about the relationships of the marine ecosystem services with latitude and biodiversity. We estimated the latitudinal patterns and relationships with the biodiversity of potential stocks of three major reef fish‐based ecosystem services (fisheries production, aquarium fish production, and recreational diving) at ten coral habitats from tropical to temperate zones in the Kuroshio Current region (8°37′N–33°24′N) using field survey data and information from relevant websites and administrative statistics. We found a latitudinal declin from south to north in potential stocks of aquarium fish production and diving in this region, whereas the peaks of fisheries production were found around both tropical and sub‐tropical zones. Our results also showed strong positive effects of biodiversity on potential stocks of the three ecosystem services, highlighting the importance of conserving diverse fish species to sustain multiple services at high levels. Broad spatial patterns of the reef fish‐based ecosystem services are useful as baselines for future evaluation of their changes. As the effects of climate change on reef fishes are predicted to vary among different latitude zones, our estimates of the ecosystem services infer specific management and economic actions for the respective zones against climate change.
