To show how dramatic global climate change affects marine ecosystem species in different habitats. We used a joint species distribution model (SDM) and an ecological niche model (ENM) to investigate the suitable habitat shifts and ecological niche overlaps of the Tridentiger fishes. In the present study, the SDM results showed that 5 hotspots were identified for T. trigonocephalus and T. barbatus, and 4 hotspots for T. bifasciatus. The study on center-of-mass transfer revealed notable reductions in the habitual range of the three Tridentiger species with future climate change and no significant bipolar shifts in the center of mass. The ENM results indicated that T. trigonocephalus and T. barbatus exhibited the greatest ecological niche overlap with Schoener's D (D) and Hellinger-based I (I) values of 0.4719 and 0.7690, respectively. Both SDM and ENM results have suggested that T. trigonocephalus occupied a wider distribution and greater adaptability to future climate change. This study sought to measure the variations in the effects of global climate change on marine species in different habitats. Our study first found that intertidal species with specific life histories may be more resilient to environmental change.
为了展示全球气候变化对不同生境海洋生态系统物种的影响有多么剧烈，我们使用联合物种分布模型（SDM）和生态位模型（ENM）来研究三齿鲨属鱼类的适宜栖息地转移和生态位重叠。在本研究中，SDM 结果表明，已确定有 5 个热点区域适合 T. trigonocephalus 和 T. barbatus，有 4 个热点区域适合 T. bifasciatus。对质心转移的研究表明，在未来的气候变化下，三种三齿鲨的惯常范围显著减少，而质心没有明显的两极转移。ENM 结果表明，T. trigonocephalus 和 T. barbatus 与 Schoener 的 D（D）和基于 Hellinger 的 I（I）值的生态位重叠最大，分别为 0.4719 和 0.7690。SDM 和 ENM 的结果都表明，T. trigonocephalus 占据了更广泛的分布范围，对未来的气候变化有更强的适应能力。本研究旨在衡量全球气候变化对不同生境海洋物种的影响变化。我们的研究首次发现，具有特定生活史的潮间带物种可能对环境变化更具弹性。
