Asexual fitness
In males, asexual fitness was significantly affected by treatment (LRT, Negative binomial GLMM with linear parametrization, λ2= 26.96, p < 0.001). The number of buds produced increased if polyps were exposed to a simulated summer heat wave and if they were cultured under elevated winter temperatures, or they received both treatments compared to a cold summer-cold winter scenario (Table 1, Fig. 4A.). In females, by contrast, treatment had no effect on asexual fitness (LRT, Negative binomial GLMM with quadratic parametrization, λ2 = 6.11, p = 0.106).
