The Mediterranean Sea is a highly susceptible area to climate change, that facilitates the introduction of warm-affinity exotic species, contributing to the expansion of their biogeographical range. One such thermophilic species is the Atlantic fish Seriola fasciata, which has colonised this area over the past three decades. The present study analyzed its spatial distribution in the Mediterranean Sea to identify aggregation areas and dynamics over time, and the environmental predictors influencing its presence. The utilized statistical tools and the Species Distribution Model proved effective in identifying specific spatial and temporal distribution patterns, as well as discerning some environmental variables influencing the species presence, with distinctions recorded between juveniles and adults. S. fasciata was observed to be established in the central Mediterranean, with Fishing Aggregating Devices potentially influencing its presence, particularly of juveniles. Sea floor temperature and habitats emerged as the primary factors driving species distribution. An aggregation area in the Levant Sea, conducive mainly for the adults, was identified and is expected to intensify over time. These findings contribute valuable insights into a relatively understudied species and its presence in the Mediterranean Sea, where climate change is affecting marine biodiversity.
地中海是一个极易受到气候变化影响的地区，这使得温暖偏好的外来物种更容易引入，并促进了它们生物地理范围的扩张。其中一种嗜热物种是大西洋鱼类黄鳍鲷，它在过去三十年中已经在该地区繁殖。本研究分析了其在地中海的空间分布，以确定其聚集区和随时间的动态变化，并确定影响其存在的环境预测因子。所使用的统计工具和物种分布模型在确定特定的时空分布模式以及识别影响物种存在的一些环境变量方面非常有效，在幼鱼和成鱼之间记录到了一些区别。黄鳍鲷已在中地中海地区建立了种群，渔捞聚集装置可能会影响其存在，尤其是对幼鱼的存在有影响。海底温度和生境是驱动物种分布的主要因素。在黎凡特海发现了一个主要有利于成鱼的聚集区，预计随着时间的推移，该聚集区会加剧。这些发现为气候变化影响海洋生物多样性的地中海地区一个相对研究较少的物种及其存在提供了有价值的见解。
