title: Determinants of Life-history Evolution in Nematodes.
abstract: What are the determinants of parasite life-history evolution? Does life-history evolution of parasitic species differ from their free-living relatives? How and why do host and parasite life-history traits covary? Here, Serge Morand and Gabriele Sorci use recent comparative studies to investigate life-history evolution in nematodes which present both parasitic and free-living groups. Application of life-history theory to nematodes suggests that the conventional wisdom concerning the high fecundity of parasitic species could simply be the result of the larger body size of the latter when compared with free-living forms. The authors also emphasize, with the use of examples, that in most cases parasite life-history evolution depends on host features.
