A comparative study of the life strategies of two bacterial-feeding nematodes under laboratory conditions. 1, Influence of culture conditions on selected life-history parameters of Acrobeloides nanus (de Man 1880) Anderson 1968 and Dolichorhabditis dolichura (Schneider 1866) Andrássy 1983

Pages 29-43 : illustrations 27 cm Bibliographical references (pages 41-43) Selected life-history parameters like age of maturity, fecundity, egg development time, pattern of growth and reproduction, longevity and intrinsic rate of natural increase (r) were compared for two bacterial-feeding nematode species in xenic (with a several bacterial species as food) and monoxenic (with a bacteria Sporosarcina sp. as a food organism) agar cultures at 20° C.There were pronounced differences in the life-history patterns of the two species in both types of culture conditions. D. dolichura showed a higher growth and development rate than A. nanus. D. dolichura had a shorter pre-reproductive period, a shorter reproductive period but more intensive pattern of reproduction, a shorter total life span and a considerably greater r than A. nanus.The differences in life-history traits of the two nematode species were discussed with reference to their adaptive significance for habitat properties. While D. dolichura represents short-lived habitats with temporarily high food supply, A. nanus can be found in habitats of various food abundance.
