呼吸器官的供氧解释了脊椎动物生命树的需氧模式。代谢率是从细胞动力学到生态系统结构和功能等一系列现象的基础。试图统计解释脊椎动物代谢率变化的模型主要基于体型和温度。出乎意料的是，这些模型忽略了鳃和肺的大小变化，而鳃和肺获取了有氧过程所需的氧气。在这里，我们使用新颖的系统发育贝叶斯多级建模框架以及代谢率和呼吸表面积的物种配对数据集来评估呼吸表面积在解释整个脊椎动物生命树的代谢率模式中的重要性。我们发现，在脊椎动物生命树中，呼吸表面积对代谢率变化的解释是温度的两倍。了解氧气获取和运输的结合为了解代谢率的进化历史和改进量化气候变化影响的模型提供了机会。
Oxygen supply from respiratory organs explains patterns of oxygen demand across the vertebrate tree of life. Metabolic rate underlies a wide range of phenomena from cellular dynamics to ecosystem structure and function. Models seeking to statistically explain variation in metabolic rate across vertebrates are largely based on body size and temperature. Unexpectedly, these models overlook variation in the size of gills and lungs that acquire the oxygen needed to fuel aerobic processes. Here, we assess the importance of respiratory surface area in explaining patterns of metabolic rate across the vertebrate tree of life using a novel phylogenetic Bayesian multilevel modeling framework coupled with a species-paired dataset of metabolic rate and respiratory surface area. We reveal that respiratory surface area explains twice as much variation in metabolic rate, compared to temperature, across the vertebrate tree of life. Understanding the combination of oxygen acquisition and transport provides opportunity to understand the evolutionary history of metabolic rate and improve models that quantify the impacts of climate change.
