海洋潮间带的特点是温度、pH值、溶解氧以及营养物和食物的供应在季节和每日时间尺度上变化很大。这些海洋波动驱动的生态过程，如招聘，竞争和消费者-猎物的相互作用，主要是通过生理机制。因此，要了解沿海生态系统的动态和对气候变化的反应，关键是要了解这些机制。在这里，我们利用转录组分析贻贝加州贻贝在不同的空间尺度的生理反应，以深入了解这些机制。我们使用贻贝栖息在不同的垂直位置内草莓山的Perpetua角，OR和锅炉湾的Foulweather角，OR研究间和网站内的基因表达的变化。结果突出了两个不同的基因表达的签名相关的代谢活动的循环和扰动细胞内稳态。中间的空间尺度显示出强烈的影响，海洋学差异的食物和应力环境之间的网站分开约65公里。总之，这些对基因表达的环境控制的新见解可能有助于理解人群内和人群间的重要生理驱动因素。
The marine intertidal zone is characterized by large variation in temperature, pH, dissolved oxygen and the supply of nutrients and food on seasonal and daily time scales. These oceanic fluctuations drive of ecological processes such as recruitment, competition and consumer-prey interactions largely via physiological mehcanisms. Thus, to understand coastal ecosystem dynamics and responses to climate change, it is crucial to understand these mechanisms. Here we utilize transcriptome analysis of the physiological response of the mussel Mytilus californianus at different spatial scales to gain insight into these mechanisms. We used mussels inhabiting different vertical locations within Strawberry Hill on Cape Perpetua, OR and Boiler Bay on Cape Foulweather, OR to study inter- and intra-site variation of gene expression. The results highlight two distinct gene expression signatures related to the cycling of metabolic activity and perturbations to cellular homeostasis. Intermediate spatial scales show a strong influence of oceanographic differences in food and stress environments between sites separated by ~65 km. Together, these new insights into environmental control of gene expression may allow understanding of important physiological drivers within and across populations.
