摘要/Abstract

摘要： 种群内生物个体间代谢表型的变异普遍存在于生活史的各个阶段，已成为一个新兴的重要研究领域。尽管这种代谢表型个体变异的现象随处可见，然而这种变异性是否稳定存在至今尚无定论。为了探讨鱼类代谢表型的个体变异及其可重复性，本研究以中华倒刺鲃（Spinibarbus sinensis）为动物模型，分别于不同时间尺度下（0 d、5 d、15 d、30 d）测定了实验鱼的静止代谢率（resting metabolic rate, RMR）。结果表明：在较短的时间尺度内（0～5 d, 0～15 d），实验鱼RMR的个体变异具有可重复性（P<0.05），而在较长的时间尺度内（0～30 d），RMR个体变异的重复性消失（P>0.05）；中华倒刺鲃代谢表型的个体变异仅具有相对的可重复性。

Abstract: Interindividual variation in metabolic phenotype is ubiquitous at all stages of life, which has been the focus of an emerging research area. Although the phenomenon of individual’s metabolic phenotypic variability is omnipresent, there is no consensus on the repeatability of this variability. To reveal the individual variation and its repeatability in metabolic phenotype of fish, we investigated the resting metabolic rate (RMR) of Spinibarbus sinensis at different time scales (0, 5, 15, and 30 days). Our results showed that individual variation in RMR was relatively repeatable over short term (0 to 15 days; P<0.05), while the repeatability disappeared over longer time periods (30 days; P>0.05). The results indicated that inter-individual variation in metabolic phenotype of S. sinensis was relatively repeatable.
