阿克里尼乌斯方程已成为最受欢迎的模型，用于描述温度依赖性的消费在捕食者-猎物模型。为了研究这个方程的相关性，我们对功能反应参数和温度之间的关系进行了荟萃分析。我们发现，当绘制在线性对数空间中，温度依赖性的攻击率和最大摄入率表现出驼峰形的关系，而不是一个线性的预测由Arrhenius方程。该关系仍然显着向下凹，即使当数据从温度高于峰的驼峰被丢弃。攻击率对温度的依赖性比最大摄食率强，但热最佳值没有不同。我们的结论是，使用的Arkyius方程来描述消费的捕食者-猎物模型需要的假设，温度以上的热最佳是不重要的人口和社区动态，假设是站不住脚的现有数据。
The Arrhenius equation has emerged as the favoured model for describing the temperature dependence of consumption in predator-prey models. To examine the relevance of this equation, we undertook a meta-analysis of published relationships between functional response parameters and temperature. We show that, when plotted in lin-log space, temperature dependence of both attack rate and maximal ingestion rate exhibits a hump-shaped relationship and not a linear one as predicted by the Arrhenius equation. The relationship remains significantly downward concave even when data from temperatures above the peak of the hump are discarded. Temperature dependence is stronger for attack rate than for maximal ingestion rate, but the thermal optima are not different. We conclude that the use of the Arrhenius equation to describe consumption in predator-prey models requires the assumption that temperatures above thermal optima are unimportant for population and community dynamics, an assumption that is untenable given the available data.
