Abstract
The effect of temperature on respiration rate has been established, using Cartesian divers, for the meiofaunal sabellid polychaete Manayunkia aestuarina, the free-living nematode Sphaerolaimus hirsutus and the harpacticoid copepod Tachidius 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 (Rc) was related to the temperature (T) in °C by the equation Log10Rc=-0.635+0.0339 T for Manayunkia, Log10Rc=0.180+0.0069 T for Sphaerolaimus and Log10Rc=-0.428+0.0337 T for Tachidius, being equivalent to Q10 values of 2.19, 1.17 and 2.17 respectively. In order to derive the temperature response for Manayunkia a relationship was first established between respiration rate and body size: Log10R=0.05+0.75 Log10V where R=respiration in nl·O2·ind-1·h-1 and V=body volume in nl. The Q10 values are compared with values for other species derived from the literature. From these limited data a dichotomy emerges: species with a Q10{difference between}2 which apparently feed on diatoms and bacteria, the abundance of which are subject to large short term variability, and species with Q10{difference between}1 apparently dependent on more stable food sources.
