Ridge Flank Hydrothermal Systems have discrete pockets of fluid discharge that mimic climate-induced ocean warming. Unlike traditional hydrothermal fluids, those discharged by Ridge Flank Hydrothermal Systems have a chemical composition indistinguishable from background water, enabling evaluation of the effect of warming temperature. Here we link temperature and terrain variables to community composition and biodiversity by combining remotely operated vehicle images of vent and non-vent zone communities with associated environmental variables. We show overall differences in composition, family richness, and biodiversity between zones, though richness and diversity were only significantly greater in vent zones at one location. Temperature was a contributing factor to observed greater biodiversity near vent zones. Overall, our results suggest that warming in the deep sea will affect species composition and diversity. However, due to the diverse outcomes projected for ocean warming, additional research is necessary to forecast the impacts of ocean warming on deep-sea ecosystems.
脊侧翼热液系统有离散的流体排放口袋，模拟气候引起的海洋变暖。与传统的热液流体不同，脊侧翼热液系统排放的流体在化学成分上与背景水无法区分，这使得可以评估变暖温度的影响。在这里，我们通过将遥控潜水器拍摄的喷口和非喷口区域群落的图像与相关环境变量相结合，将温度和地形变量与群落组成和生物多样性联系起来。我们表明，尽管在一个地点，喷口区的丰度和多样性仅显著更高，但在各个区域之间存在组成、科丰富度和生物多样性的总体差异。温度是导致在喷口区附近观察到更高生物多样性的一个因素。总的来说，我们的结果表明，深海的变暖将影响物种组成和多样性。然而，由于对海洋变暖的预测结果各不相同，因此有必要进行更多的研究来预测海洋变暖对深海生态系统的影响。
