Abundances and biomasses in different treatments in the 32 day experiment. (A) Mean total (B) adult and (C) juvenile abundances (± SE) of Daphnia magna in uninfected control populations fed with P-sufficient (HP, denoting for high P) or P-limited (LP, denoting for low P) green algae and in populations infected with a microsporidian Glugoides intestinalis (HPinf and LPinf), (D) Mean carbon biomass mg C L-1 (± SE) in all four treatments and relative biomass (± SE) of the infected populations for the P-sufficient (HP) and P-limited (LP) treatments during the experiment, (E) Mean individual size of adult, and (F) juvenile Daphnia μg C (± SE). The populations were started with 10 juveniles each born to uninfected mothers fed with P-sufficient algae, and half of the animals were infected before allocation to feeding treatments. See Materials and methods for calculation of relative biomass. Note that the abundances are given per population in 0.5 L vials to emphasise the actual densities, while biomass is given per L to aid comparison with previously published results. The legend in panel (A) applies to treatments in all panels (A) - (F), while the legend in panel (D) indicates the relative biomass in panel (D).
