上升流区域是各种海洋掠食者和工业渔业的高生产力生境。在这项研究中，我们跟踪八种海鸟的迁徙运动，从大西洋两岸;量化与加那利电流大型海洋生态系统（CCLME）的重叠，并确定驱动这种关联的栖息地特征。我们的研究结果表明，CCLME是一个生物多样性的热点迁徙海鸟;所有跟踪的物种和超过70%的个人使用这个上升流区域。相对物种丰富度在平均海表温度在15至20摄氏度之间的地区达到峰值，并与叶绿素a呈正相关，这表明海鸟自下而上产生营养效应的最佳条件。海洋脊椎动物不受国际边界的限制，这使得保护具有挑战性。然而，通过将多样性与海洋生产力联系起来，我们的研究揭示了CCLME对大西洋沿岸海鸟种群的重要性，使其成为保护行动的优先事项。
Upwelling regions are highly productive habitats targeted by wide-ranging marine predators and industrial fisheries. In this study, we track the migratory movements of eight seabird species from across the Atlantic; quantify overlap with the Canary Current Large Marine Ecosystem (CCLME) and determine the habitat characteristics that drive this association. Our results indicate the CCLME is a biodiversity hotspot for migratory seabirds; all tracked species and more than 70% of individuals used this upwelling region. Relative species richness peaked in areas where sea surface temperature averaged between 15 and 20°C, and correlated positively with chlorophyll a, revealing the optimum conditions driving bottom-up trophic effects for seabirds. Marine vertebrates are not confined by international boundaries, making conservation challenging. However, by linking diversity to ocean productivity, our research reveals the significance of the CCLME for seabird populations from across the Atlantic, making it a priority for conservation action.
