气候变化正在导致沿海鱼类物种的地理分布向更高纬度转移。然而，今天在高纬度地区发现的当地鱼类群落不只是过去在低纬度地区发现的鱼类群落，因为物种对不同环境条件的敏感性不同。鱼类对环境条件的反应取决于它们的生活史特征，如最大种群增长率、成熟期和世代时间，因为这些特征受到环境条件的限制。在这里，我们研究有无(发病率)数据中的时间模式、物种的生活史特征和环境条件之间的关联，以阐明气候变化对沿海鱼类群落影响的潜在机制。在这项研究中，使用广义加性模型对1982年至2019年在墨西哥湾西北部八个主要海湾每半年收集一次的鱼类监测数据进行了分析。估计了77个物种的发病数据中随季节和年份的平滑格局，并将这些数据与环境变量相关联。此外，这些时间模式与物种的生活史特征有关。结果表明，夏季常见的物种(非冬季产卵者)呈增加趋势，春季常见的物种(冬季产卵者)呈减少趋势，这表明夏季条件在推动热带化中的重要性。盐度总体上对物种有显著影响，寿命较长的物种往往受温度的影响。这些结果表明，在不同的生活史策略中，环境条件的影响和对环境条件的敏感度的差异存在季节差异。这些发现是朝着理解河口群落热带化背后的机制迈出的重要一步。
Climate change is causing shifts in the geographic distributions of coastal fish species toward higher latitudes. However, local fish communities found in higher latitudes today are not simply those found in lower latitudes in the past because the sensitivity of species to various environmental conditions is different. Responses of fish to environmental conditions differ depending on their life‐history traits such as the maximum population growth rate, age of maturity, and generation time because these traits are constrained by environmental conditions. Here, we investigate associations among temporal patterns in presence–absence (incidence) data, life‐history traits of species, and environmental conditions to elucidate the potential mechanisms behind the effects of climate change on coastal fish communities. In this study, fish monitoring data collected semi‐monthly between 1982 and 2019 from eight major bays in the northwestern Gulf of Mexico were analyzed with generalized additive models. Smooth patterns over seasons and years in the incidence data of 77 species were estimated, and the data were associated with environmental variables. Further, these temporal patterns were associated with the life‐history traits of species. The results show that species that are more common in the summer months (non‐winter spawners) tend to exhibit an increasing trend and that species common during the spring (winter spawners) tend to exhibit a decreasing trend, suggesting the importance of summer conditions in driving tropicalization. Salinity had significant effects on species in general, and longer‐lived species tended to be affected by temperature. These results suggest seasonal differences in the effects of environmental conditions and variation in sensitivity to environmental conditions among different life‐history strategies. These findings represent major steps toward understanding the mechanisms behind the tropicalization of estuarine communities.
