The dolphinfish (Coryphaena hippurus Linnaeus, 1758) is an epipelagic top-predator that is globally distributed in tropical and subtropical waters. In the Eastern Tropical and Subtropical Pacific, this fish represents a target species for commercial and recreational fisheries. Climate change is affecting biodiversity, and a poleward expansion was suggested for dolphinfish due to its affinity for warm waters. Considering that hypothesis, the objective of this research is to model the historical distribution of dolphinfish within the northern limit of its distribution in the Eastern Tropical Pacific and to evaluate the potential distribution shift along the North American temperate coast due to environmental changes under climate change scenarios. According to the Ecological Niche Model, a poleward shift in dolphinfish distribution is expected during this century as a consequence of gradual northern displacement of the sea surface temperature isotherm along the North American coast.

沿南加州洋流系统的海豚鱼 (Coryphaena hippurus) 的潜在极地分布转移

海豚鱼 (Coryphaena hippurus Linnaeus, 1758) 是一种远洋顶级捕食者，全球分布于热带和亚热带水域。在东热带和亚热带太平洋，这种鱼是商业和休闲渔业的目标物种。气候变化正在影响生物多样性，由于海豚对温暖水域的亲和力，建议向极地扩张。考虑到这一假设，本研究的目的是模拟海豚在热带东太平洋分布的北部界限内的历史分布，并评估气候变化情景下环境变化导致的沿北美温带海岸的潜在分布变化. 根据生态位模型，
