Fig. 1. Female lifespan characteristics (mean ± se) for the sexual A. tunisiana population from Bonmati (BMT) and the A. parthenogenetica
populations from La Mata (LMT) and La Trinidad (LTR) as a function of temperature. When error bars are not displayed standard errors are
smaller than symbol size.
Table 4. Two-way ANOVA analyses of lifespan components and the percentage of
encysted offspring given in Figs I and 4 for the parthenogenetic strains at 15 0, 24 °
and 29.5 0c. Significance level (S.L.). Abbreviations for populations are explained
in Table I.
