利用生境适宜性指数（HSI）模型，研究了1950-2015年西北太平洋虹膜飞乌贼（Ommastrephes bartramii）和东南太平洋巨型飞乌贼（Dosidicus gigas）栖息地格局的年代际变化。HSI模型涉及两个环境驱动因素导致了ofO的发生。bartramiiandD。gigas：海面温度（SST）和海面高度异常（SSHA）。结果表明，两种鱿鱼的环境变异性和生境变化具有明显的“跷跷板”特征，与正、负太平洋年代际涛动（PDO）的变化相一致。在PDO负相位，o渔场海温异常和SSHA增加。bartramii。o适宜栖息的区域。由于适当的SST和SSHA的减少，bartrimi明显收缩。与此相反，d渔场海温降温，SSHA减小。负PDO阶段的gigas导致了更适宜的海温和SSHA的形成，产生了更广阔的适宜栖息地forD。牡蛎。此外，最有利的海温为o。bartramiiandD。在负PDO状态下，gigasas向北移动，两种乌贼的适宜栖息地也向北部地区转移。当气候变化进入PDO正相位时，两种鱿鱼的响应与PDO负相位相反。我们的研究结果表明，o栖息地模式的年际-年代际变化。bartramiiandD。可以从太平洋的气候变化中探测到gigasas。
Trans-Pacific changes in the habitat patterns of neon flying squid (Ommastrephes bartramii) in the Northwest Pacific Ocean and jumbo flying squid (Dosidicus gigas) in the Southeast Pacific Ocean during 1950–2015 were examined on a decadal scale using a habitat suitability index (HSI) model. The HSI model involved two environmental drivers for the occurrence ofO. bartramiiandD. gigas: sea surface temperature (SST) and sea surface height anomaly (SSHA). Significant seesaw-like patterns of environmental variability and habitat changes, consistent with the regime shift of positive and negative Pacific Decadal Oscillation (PDO), were observed for the two squid species. In a negative PDO phase, SST anomaly and SSHA increased on the fishing grounds ofO. bartramii. The areas of suitable habitat ofO. bartramiicontracted markedly due to the decrease in suitable SST and SSHA. In contrast, cooling SST and decreasing SSHA on the fishing grounds ofD. gigasduring a negative PDO phase led to the formation of more suitable SST and SSHA, yielding expansive suitable habitats forD. gigas. Moreover, the most favorable SST forO. bartramiiandD. gigasmoved northward in the negative PDO regime, and the suitable habitat for both squids shifted into the northern regions as well. When the climate regime shifted into a positive PDO phase, the responses of the two squids were opposite to those in the negative PDO phase. Our findings indicate that interannual-to-decadal variability in habitat patterns ofO. bartramiiandD. gigascan be detected from climate regime shifts in the Pacific Ocean.
