项目摘要

In animals, metabolism is measured by uptake of oxygen and secretion of carbon dioxide. Either direct changes in the environment (e.g. climate change, hypoxia or changes in salinity) or by exposure to environmental toxicants such as hydrocarbons, pharmaceuticals and other pollutants can change availability of either gas in the environment. Oxygen and carbon dioxide levels may change over the short term, but they have also changed over earth's history. Tolerances of modern animals to different levels of these gases can therefore be informative about the evolution of early animals. In this proposal, 5 University of Alberta scientists with a history of cross-disciplinary engagement and collaboration request a system of sensors, meters and chambers to be constructed as a combined system to measure and also deliver precise levels of oxygen and carbon dioxide gases to animals. The research equipment will provide the ability to measure oxygen and carbon dioxide in environmental chambers ranging in size from a 200 microlitres to whole ocean ecosystems at depth. This will allow us the flexibility to measure oxygen and carbon dioxide use in animals and environments at multiple scales. The proposed system will be used collaboratively by a wide variety of researchers in the aquatic sciences (physiology, toxicology, ichnology and earth sciences) but also be available to other disciplines.

动物的新陈代谢是通过吸收氧气和分泌二氧化碳来衡量的。环境的直接变化（例如气候变化、缺氧或盐度变化）或暴露于碳氢化合物、药物和其他污染物等环境毒物都可能改变环境中任一种气体的可用性。氧气和二氧化碳的含量可能会在短期内发生变化，但它们也会在地球的历史中发生变化。因此，现代动物对不同水平的这些气体的耐受性可以为早期动物的进化提供信息。在这项提案中，阿尔伯塔大学的5位具有跨学科参与和合作历史的科学家要求将传感器，仪表和室系统构建为一个组合系统，以测量并向动物提供精确的氧气和二氧化碳气体水平。研究设备将提供测量环境舱中氧气和二氧化碳的能力，这些环境舱的大小从200微升到深处的整个海洋生态系统。这将使我们能够灵活地测量动物和环境在多个尺度上对氧气和二氧化碳的使用。拟议的系统将由水生科学（生理学、毒理学、技术和地球科学）的各种研究人员协作使用，但也可用于其他学科。
