Abstract
    Measurements of population growth, generation time, fecundity and respiration in laboratory culture have been made, in relation to temperature and salinity, for the nematode Diplolaimelloides bruciei Hopper, a species normally associated with decayed material of the marsh grass Spartina. The intrinsic rate of increase (r) is high: it is related to temperature between 5 degree and 25 degree C by a sigmoid function which is steepest between 10 degree and 15 degree C, and is maximum at 26ppt. salinity. Generation time is related to temperature by a power function and is shortest at 26ppt. salinity. The effect of temperature on generation time is consistent with other data for marine nematodes, and the steep slope of r against temperature is largely due to the marked effect of temperature on fecundity. A sex ratio of 2:1 in favour of males is maintained regardless of culture conditions or population density. Respiration increases exponentially with temperature between 5 degree and 25 degree C, with a very high Q10 (3.94), but is not affected by salinity.
