气候变化影响海洋的物理和化学特性，这些变化影响海洋生物的生态。气候变化的一个重要生态后果是海洋物种的分布向高纬度转移。在这里，近150种鱼类和无脊椎动物的患病率进行了调查，以发现其分布的变化，沿着墨西哥湾内的亚热带海岸超过35年。我们的研究结果表明，90种增加了他们的占用概率，而33个下降（其余物种既不增加也不减少），和许多物种的范围扩大。使用稀疏分析，这使得物种多样性的估计，我们表明，物种多样性增加了整个德克萨斯州海岸。气候介导的环境变量与占用概率的变化有关，表明热带物种向该地区的扩张正在增加多样性。
Climate change impacts physical and chemical properties of the oceans, and these changes affect the ecology of marine organisms. One important ecological consequence of climate change is the distribution shift of marine species toward higher latitudes. Here, the prevalence of nearly 150 species of fish and invertebrates were investigated to find changes in their distributions over 35 years along a subtropical coast within the Gulf of Mexico. Our results show that 90 species increased their occupancy probability, while 33 decreased (remaining species neither increase or decrease), and the ranges of many species expanded. Using rarefaction analysis, which allows for the estimation of species diversity, we show that species diversity has increased across the coast of Texas. Climate-mediated environmental variables are related to the changes in the occupancy probability, suggesting the expansion of tropical species into the region is increasing diversity.
