ABSTRACT: Climate change causes warming of the oceans, and there is consensus that many marine ectotherms, including marine invertebrates and fishes, respond to the increase in temperature by showing latitudinal range shifts in their distribution. However, the effect of ocean warming on the bathymetric distribution of marine ectotherms remains largely theoretical, and few works evidence bathymetric range shifts. Since warming is not exclusive of surface waters, the depth distribution of species should also be affected by warming. Here, I exemplify bathymetric distribution ranges of marine ectotherms from the North Atlantic and advocate that there will be species-specific shifts in the fundamental ecological niches occupied in response to climate warming. Combined temperature and pressure acclimation to match oxygen capacity demands at physiological thresholds is key to this process. Species-specific tolerance of hydrostatic pressure and temperature determines depth distribution ranges of marine ectotherms.

气候变暖影响海洋外热的深度分布

摘要：气候变化导致海洋变暖，并且已经达成共识，许多海洋外温，包括海洋无脊椎动物和鱼类，通过显示其纬度分布范围的变化来应对温度的升高。但是，海洋变暖对海洋等温线等深线分布的影响仍然在很大程度上是理论上的，很少有研究证明等深线范围发生变化。由于变暖不仅仅限于地表水，因此物种的深度分布也应受变暖的影响。在这里，我举例说明了北大西洋海洋等温线的等深线分布范围，并主张应对气候变暖所占据的基本生态位将发生特定物种的转变。结合温度和压力适应以适应生理阈值上的氧气容量需求是此过程的关键。特定种类的静水压力和温度公差决定了海洋等温线的深度分布范围。
