In our recent Current Biology paper [1], we describe an ocean warming experiment in which we manipulated the temperature of panels set on the seafloor to provide a realistic and relevant indication of how benthic communities may change under future ocean warming. We describe increases in growth associated with warming by 1°C, with growth rates up to doubled in some species. The definition of Q is a measure of the temperature sensitivity of an enzymatic reaction rate or a physiological process due to an increase by 10°C; doubling of growth rates with a 1°C change gives Qs around 1,000. In his correspondence, Jaap van der Meer [2] questions our methods and provides alternative analyses which lead him to conclude that our observed increases in growth rate were in fact much lower and in accordance with previous studies from temperate zones. We provide justification for our use of absolute growth rate, justification for not using instantaneous growth rate (or a measure of growth in proportion to previous growth) and encourage the on-going discussion of how to measure and compare growth rates.
在我们最近发表于《当代生物学》的论文中[1]，我们描述了一项海洋升温实验，通过控制放置在海底的面板温度，为未来海洋升温条件下底栖生物群落可能发生的变化提供了现实而相关的指示。我们发现，升温 1°C 会导致生物生长增加，一些物种的生长率甚至增加了一倍。Q 值的定义是由于温度升高 10°C 而导致酶反应速率或生理过程的温度敏感性的度量；生长率的翻倍变化与 1°C 的变化相对应，得出 Q 值约为 1000。在他的信件中，雅普·范德米尔[2]对我们的方法提出了质疑，并提供了替代分析，使他得出结论，即我们观察到的生长率增加实际上要低得多，并且与来自温带地区的先前研究一致。我们为使用绝对生长率提供了理由，也为不使用瞬时生长率（或与以前生长成正比的生长度量）提供了理由，并鼓励就如何衡量和比较生长率进行持续讨论。
