Summary
Growth and respiration were measured in a species of Anonchus (Nematoda: Plectidae) at 5°C, 10°C, 15°C, 20°C and 25°C. At 5°C no growth was measurable but the organisms remained active. Maximum production occurred at 15°C, but the highest rate of growth occurred at 20°C. Thus, adult size attained is dependent on the temperature of growth. Respiratory energy losses derived from Cartesian diver microrespirometry, increased with temperature up to 25°C. Regression coefficients (b values) derived from a log log linear regression of weight against oxygen consumption varied between 0.574–1.793, the lowest value being attained at 5°C, the highest at 20°C. Based on Q10, production and respiratory energy losses the optimum temperatures for Anonchus appears to lie between 10°C–15°C.
