Eggs collected from mothers raised on S. obliquus (Scen), S. obliquus supplemented with either handle liposomes ( lipo) or liposomes containing ARA or EPA (ARA, EPA), N. limnetica (Nanno), or Cryptomonas sp. (Crypto). Data are presented on a logarithmic scale as implies of 3 replicates s.d.Cryptomonas sp. contained the three C18 PUFAs LIN, ALA, and STA and, moreover, considerable amounts of EPA, albeit in a lot reduced concentrations than N. limnetica, and small amounts of DHA.PUFA profiles of D. magna eggsdetected in eggs made on ARA- or EPA-supplemented S. obliquus, indicating that these supplemented PUFAs were allocated into the eggs (Figure 1).Susceptibility of the hostEggs essentially reflected the PUFA composition of their mothers’ food supply. In eggs created on a S. obliquus diet program no PUFAs of far more than 18 C atoms could possibly be detected (Figure 1). Eggs of N. limnetica-consuming mothers contained considerable amounts of ARA and EPA. When mothers exactly where raised on Cryptomonas sp., their eggs contained EPA and also low amounts of ARA, even though ARA couldn’t be detected in Cryptomonas sp. Supplementation of S. obliquus with manage liposomes didn’t affect the PUFA composition of the made eggs. In contrast, low amounts of ARA or EPA wereThe parasite’s accomplishment in establishing an infection in spore-exposed hosts varied with food top quality, irrespective of irrespective of whether the meals sources had been consumed directly (aspect “food”, df = 5, deviance = 16.58, p 0.01; Figure 2a) or had been experienced only as maternal provisioning in the second generation experiment, where all offspring had been raised on S. obliquus, irrespective of the food regimes their mother had been raised on (aspect “food”, df = 5, deviance = 37.65, p 0.001; Figure 2b). However, direct and maternal effects differed substantially in pattern and extent. When animals had been raised directly around the unique food sources, the infection efficiency dropped significantly on aFigure two Infection efficiency of P. ramosa in D. magna. a) Animals raised on distinct food sources directly. b) Animals raised exclusively on S. obliquus, but mothers raised on unique food sources.
