The effect of temperature on respiration rate has been established, using Cartesian divers, for the meiofaunal sabellid polychaeteManayunkia aestuarina, the free-living nematodeSphaerolaimus hirsutus and the harpacticoid copepodTachidius discipes from a mudflat in the Lynher estuary, Cornwall, U.K. Over the temperature range normally experienced in the field, i.e. 5-20° C the size-compensated respiration rate (R ) was related to the temperature (T) in °C by the equation Log R =-0.635+0.0339T forManayunkia, Log R =0.180+0.0069T forSphaerolaimus and Log R =-0.428+0.0337T forTachidius, being equivalent toQ values of 2.19, 1.17 and 2.17 respectively. In order to derive the temperature response forManayunkia a relationship was first established between respiration rate and body size: Log R=0.05+0.75 Log V whereR=respiration in nl·O·ind·h andV=body volume in nl.TheQ values are compared with values for other species derived from the literature. From these limited data a dichotomy emerges: species with aQ ≏2 which apparently feed on diatoms and bacteria, the abundance of which are subject to large short term variability, and species withQ ≏1 apparently dependent on more stable food sources.
利用笛卡儿浮沉子，对来自英国康沃尔郡林赫河口泥滩的小型多毛类沙蚕Manayunkia aestuarina、自由生活的线虫Sphaerolaimus hirsutus和猛水蚤Tachidius discipes进行了温度对呼吸率影响的研究。在该泥滩通常经历的温度范围内，即5 - 20°C，经体型校正后的呼吸率（R）与温度（T，单位为°C）的关系如下：对于Manayunkia，Log R = -0.635 + 0.0339T；对于Sphaerolaimus，Log R = 0.180 + 0.0069T；对于Tachidius，Log R = -0.428 + 0.0337T，其Q值分别相当于2.19、1.17和2.17。为了得出Manayunkia的温度响应，首先建立了呼吸率与体型之间的关系：Log R = 0.05 + 0.75 Log V，其中R为呼吸率（单位为nl·O·ind·h），V为个体体积（单位为nl）。将这些Q值与文献中其他物种的值进行了比较。从这些有限的数据中出现了一种二分法：Q值约为2的物种显然以硅藻和细菌为食，而硅藻和细菌的丰度存在较大的短期变异性；Q值约为1的物种显然依赖于更稳定的食物来源。
