| The large nematode <i>Oncholaimus oxyuris</i> Ditlevsen, 1911 is a dominant predator in a shallow polyhaline brackish-water pond in Belgium. The reproductive potential of this species was calculated as the intrinsic rate of natural increase r = 1/<i>G</i> ln <i>pN<sub>e</sub></i>, in which <i>D</i> is the generation time, <i>p</i> is the percentage of females, and <i>N<sub>e</sub></i> is the number of eggs per female. The generation time varies between 570 days at 5°C and 101 days at 25°C and is the main factor in the determination of <i>r</i>. The relationship between <i>r</i> and temperature is nearly linear and is given by... |
