Abstract

Climate change is predicted to increase the prevalence of marine heatwaves with an increase in heatwave frequency and intensity. While some studies have shown the effect of marine heatwaves in warm temperate climates and the effect of overall higher temperature in warm and cold temperate climates, it is yet not entirely understood how heatwaves impact marine urban communities in cold temperate climates. As thermal resistance might be related to selective pressures and acclimation, it seems reasonable to assume that they may have a strong impact on local fauna and flora. In the present study, we simulated an in situ high amplitude heatwave and observed the community structure and the metabolism of Bugula neritina at two time-steps after the heatwave and compared them to control communities and individuals. Contrary to our expectations, the community structure remained vastly unaffected, as did the total metabolome of B. neritina. This shows that the community was able to resist the disturbance of the heatwave. Bugula neritina additionally showed a certain metabolic resilience as the already minor differences in the metabolome between control and the heatwave treatment diminished even further between the tested time steps.

污垢群落对实验性高强度热浪表现出很强的抵抗力和新陈代谢复原力。

据预测，随着热浪频率和强度的增加，气候变化将使海洋热浪更加普遍。虽然一些研究显示了暖温带气候中海洋热浪的影响以及暖温带和寒温带气候中整体温度升高的影响，但热浪如何影响寒温带气候中的海洋城市群落还不完全清楚。由于热阻可能与选择性压力和适应性有关，我们有理由认为热浪可能会对当地动植物群产生强烈影响。在本研究中，我们模拟了一次原地高振幅热浪，并在热浪过后的两个时间阶段观察了Bugula neritina的群落结构和新陈代谢，并与对照群落和个体进行了比较。与我们的预期相反，群落结构和 B. neritina 的总代谢组都没有受到太大影响。这表明该群落能够抵御热浪的干扰。此外，由于对照组与热浪处理组之间的代谢组差异已经很小，在测试的时间步骤之间，差异进一步缩小，因此黑嘴蝇还表现出了一定的新陈代谢恢复能力。

期刊介绍： Marine Environmental Research publishes original research papers on chemical, physical, and biological interactions in the oceans and coastal waters. The journal serves as a forum for new information on biology, chemistry, and toxicology and syntheses that advance understanding of marine environmental processes. Submission of multidisciplinary studies is encouraged. Studies that utilize experimental approaches to clarify the roles of anthropogenic and natural causes of changes in marine ecosystems are especially welcome, as are those studies that represent new developments of a theoretical or conceptual aspect of marine science. All papers published in this journal are reviewed by qualified peers prior to acceptance and publication. Examples of topics considered to be appropriate for the journal include, but are not limited to, the following: – The extent, persistence, and consequences of change and the recovery from such change in natural marine systems – The biochemical, physiological, and ecological consequences of contaminants to marine organisms and ecosystems – The biogeochemistry of naturally occurring and anthropogenic substances – Models that describe and predict the above processes – Monitoring studies, to the extent that their results provide new information on functional processes – Methodological papers describing improved quantitative techniques for the marine sciences.
